HYDRAULIC PUMPS

Hydraulic pumps are utilized in hydraulic drive systems and can be either hydrostatic or hydrodynamic. A hydraulic pump is a mechanical power source that transfers mechanical power into hydraulic energy (hydrostatic energy, which includes flow and pressure). It provides flow with sufficient power to counteract the pressure caused by the load at the pump output. When a hydraulic pump functions, it creates a vacuum at the pump inlet, forcing liquid from the reservoir into the pump's input line and mechanically delivering this liquid to the pump output and forcing it into the hydraulic system.Hydrostatic pumps are positive displacement pumps, whereas hydrodynamic pumps are either fixed displacement pumps, in which the displacement (flow through the pump per pump rotation) cannot be adjusted, or variable displacement pumps, which have a more complicated construction that allows the displacement to be adjusted. Hydrodynamic pumps are more common in everyday life. Pascal's law is the underlying principle behind all hydrostatic pumps.

Gear Pumps

Gear pumps contain very few moving components, run smoothly, and perform effectively at pressures of roughly 210 bar. It is the pump with higher speeds, up to 3000-6000 rpm.

Type of gear pumps:

1. External gear pumps

2. Internal gear pump

3. Gear ring pump

4. Screw spindle pump

2. Axial piston pump, variable displacement

3. Radial piston pump, fixed displacement

4. Radial piston pump, variable displacement

Vane Pumps

Hydraulic vane pumps function with significantly lower flow pulsation, or continuous flow. As a result, vane pumps generate less noise while maintaining a high speed.

Type of Vane Pumps:

1. Vane pumps, variable displacement

2. Vane pumps, fixed displacement

HYDRAULIC VALVES

A hydraulic valve regulates the flow of a liquid medium, typically oil, through your hydraulic system. The direction of oil flow is determined by the position of a spool. Only valves can allow a hydraulic system to function properly. As a result, you should constantly look for the right type of hydraulic valve for your specific application. The needed size is determined by the hydraulic system's maximum flow through the valve and the maximum system pressure.

Directional Control Valves

Directional control valves can control the start, stop, and direction of flow of a pressure medium (such as hydraulic oil). For this reason, they are also known as switching valves. Directional control valves are classified as spool valves, poppet valves, or rotary slide valves. Due to its low operating pressure (up to 70 bar), rotary slide valves are no longer widely employed. Switching valves are directional control valves that do not provide proportional control.

Type of directional control valves:

1. Directional poppet valves

2. Directional spool valves

3. Check and non-return valves

Pressure Control Valves

Every pressure control valve operates at a predefined pressure setting. The switching pressure is often a changeable setting on the valve itself. The pressure control valve's position (open or closed) can change gradually (by control) or quickly (by switch). Pressure shut-off and pressure sequence valves are hydraulic valves with fixed throttles, whereas relief and lowering valves have variable throttles.

Type of pressure control valves:

1. Pressure valves, relief function

2. Pressure valves, reducing function

3. Pressure valves, fixed throttle

Proportional Control Valves

Proportional hydraulic valves can control the opening such that flow occurs proportionally rather than gradually, as most normal hydraulic valves do. The most basic sort of proportional hydraulic valve is a variable throttle operated by a manual lever. When your hydraulic application necessitates precise flow control, hydraulic valves can be outfitted with modern control electronics that include integrated measurement and feedback devices.

Type of proportional control valves:

1. Proportional directional control valves

2. Proportional pressure control valves

3. Proportional flow control valves

Flow Control Valves

Flow control valves regulate flow by reducing or increasing the opening at the throttling point. This contributes to determining the speed of movement for the hydraulic actuators. The simplest flow control valve design is a needle or longitudinal slot installed in the pipeline and attached to a screw that regulates the opening at the throttling point. These are known as throttle valves because the set throttle modulates the actual flow through the valve under different loads.

Type of flow control valves:

1. Flow controls, pressure compensated valves

2. Flow controls, throttle valve

HYDRAULIC FILTERATION TROLLEY

A hydraulic oil filtration unit is a small, portable filter system that can be used on-site to remove polluted oil. It is simply transported to the sump or reservoir by one person. It is totally self-contained, requiring only an electrical connection to function. The unit's standard features include a dependable gear pump and an inbuilt pressure relief valve to prevent system overload. The filter cartridge also provides excellent performance, with a minimum beta ratio of 200, and can be replaced in a matter of minutes.

ELECTRONIC DEVICE CONTROLS

A hydraulic drive system is a quasi-hydrostatic drive or transmission system that uses pressurized hydraulic fluid to power hydraulic equipment. The term hydrostatic refers to the transmission of energy based on pressure differences rather than the flow's kinetic energy.

A hydraulic drive system is made up of three parts: the generator (e.g., a hydraulic pump) powered by an electric motor, a combustion engine, or a windmill; valves, filters, piping, and so on (to guide and control the system); and the actuator (e.g., a hydraulic motor or hydraulic cylinder) that drives the machinery.

AC

AC Motor Controllers and Drives are electronic devices that modify the input power to motors by typically adjusting the frequency of the power to the motor for the purpose of regulating the output speed and torque. Key specifications include the intended application, drive operating mode, motor type, inverter type, loop system voltage classification, power rating, communication interface, as well as input and output electrical specifications.AC motor controllers and drives are used primarily in process applications to control the speed of pumps, fans, blowers, etc. They are known as variable speed drives, adjustable frequency drives, or AC inverters. The controller, commonly integrated with the drive circuits, supplies the control signals to the drive.

DC

DC Motor Controllers and Drives are electrical devices that change the input power by converting the continuous or alternating current source into a pulsed, direct current output with adjustable pulse duration or frequency. Key requirements include the intended application, drive operating mode, motor type, loop system, voltage classification, power rating, output signal type, communication interface, and electrical input and output specifications. DC motor controllers and drives are generally used for controlling motor speeds and torques in machine tools, electric cars, pumps, and other applications. The controller, which is frequently integrated with the drive circuits, sends control signals to the drive.

Servomotor

Servo Motor Controllers and Drives are electronic devices that modify the input power by adjusting the constant or alternating current source to a pulsed, current output of varying pulse duration or frequency. Key specifications include the intended application, motor type, drive operating mode, loop system, power rating, output signal type, communication interface, as well as electrical specifications. Servo motor controllers and drives are used primarily in motion control applications in manufacturing and construction environments, among others, and used to control motor speeds, torques, and positions, and may be AC or DC driven. Servo motors are used in many applications including machine tools, micro-positioning, and robotics, among many other types of machinery, such as conveyors or spindle drive systems. The controller, commonly integrated with the drive circuits, supplies the control signals to the drive. Servo drives are also known as servomotor amplifiers.

Stepper

Stepper Motor Controllers and Drives are electronic devices that modify the input power by adjusting the constant or alternating current source to a pulsed, or "stepped," current output.

Key specifications include the intended application, motor type, drive operating mode, loop system, power rating, output signal type, communication interface, as well as electrical specifications.

Stepper motor controllers and drives are used primarily in motion control applications in manufacturing and construction environments, among others, and used to control motor speeds, torques, and position. They are used in many applications including machine tools, micro-positioning, and robotics, among many other types of machinery, such as conveyors or OEM equipment. The controller, commonly integrated with the drive circuits, supplies the control signals to the drive. Stepper drives are also known as pulse drives and step amplifiers. Stepper controllers are also known as motor indexers.

HYDRAULIC HOSE PIPE

A hydraulic hose is meant to transport hydraulic fluid to or from hydraulic components such as valves, actuators, and tools. Because hydraulic systems generally work at high or extremely high pressures, they are typically flexible, reinforced, and designed with multiple layers of reinforcement. Hydraulic hose is utilized in many industrial hydraulic systems. When looking for hydraulic hose, it's crucial to evaluate dimensions, performance criteria, construction options, and features.

Important dimensions for the selection of hydraulic hose include the inside diameter, outside diameter, and minimum bend radius. Hydraulic hose sizes are denoted by the inside and outside diameter of the hose. The inside diameter refers to the inside of the hose or liner. The outside diameter is often a nominal specification for hoses of corrugated or pleated construction. Minimum bend radius is based on a combination of acceptable hose cross-section deformation and mechanical bending limit of any reinforcement.

Compact High Pressure Hydraulic Hose

In medium pressure applications, hydraulic rubber hoses with a single or double fiber braid, as well as textile covers, are commonly employed. They are suited for transferring petroleum-based hydraulic oil, air, and water at prescribed pressures to air brakes, power steering, turbo oil lines, tilt cab cylinders, hydraulic system return and suction hoses.

HYDRAULIC CYLINDERS

A hydraulic cylinder (also known as a linear hydraulic motor) is a mechanical actuator that produces a unidirectional force via a single stroke. It has numerous applications, particularly in construction equipment (engineering vehicles), manufacturing machinery, and civil engineering.

Single-Acting Cylinder

This single-acting cylinder has only one head-end port and operates hydraulically in one direction. When oil is injected into a port, it pushes a plunger, which causes it to lengthen.Draining the hydraulic oil back into a reservoir completes the return or retraction process. The plunger will fall or return due to the weight of a load or another mechanical force, such as a spring.

Double-Acting Cylinder

The Double-Acting Cylinder must have ports on both the head and rod ends. Pumping oil into the head causes the piston to move, allowing the rod to lengthen. Any oil in the rod end is expelled into a reservoir. To retract the rod, reverse the oil flow at both ends.

Nondifferential Cylinder

In a nondifferential cylinder, a piston rod extends from each end. Thrust and speed are equal in both directions, assuming that pressure and flow are stable.

Cushioned Cylinder

The cushioned cylinder is intended to slow down the movement and prevent shock loading at the end of the piston stroke. This cushion effect is generated by incorporating a restricting or metering device into the cylinder to restrict flow at the exit port, slowing the piston's motion.

HYDRAULIC FILTERS AND ACCESORIES

Hydraulic filters safeguard your hydraulic system components from harm caused by particle contamination of the oils or other hydraulic fluid in use. Every minute, about one million particles larger than one micron (0.001 mm or 1 μm) enter a hydraulic system. Hydraulic oil is easily polluted, and these particles can cause harm to its components. Thus, maintaining a robust hydraulic filtering system will extend the life of hydraulic components.

Low Pressure Filters

Low pressure filters function at pressures of 10 bar or lower. Suction filters are used for coarse filtration, whereas return line or bypass filters are used for fine filtering.

Heavy Duty Filtration

Heavy-duty filtering for demanding hydraulic applications that require continuous operation in harsh environments. It produces a high flow rate at low to medium hydraulic system pressures.

Standard Pressure Filters

Pressure line or standard hydraulic pressure filters are commonly used in a hydraulic system. It protects your hydraulic components against wear and tear.

HYDRAULIC MS TANK

The hydraulic reservoir is a container that holds the fluid needed to supply the system, as well as a reserve to offset losses due to small leakage and evaporation. The reservoir can be built to allow for fluid expansion, escape of air entrapped in the fluid, and cooling of the fluid.

Filling reservoirs to the brim during servicing leaves no room for expansion. To avoid overfilling, most reservoirs have a rim at the filler neck that is lower than the reservoir top. A reservoir typically includes a way of verifying the fluid level. This could be a glass or plastic sight gauge, tube, or dipstick. Hydraulic reservoirs are either vented or pressured.

Vented Reservoir

A vented reservoir is one that is exposed to ambient pressure via a vent line. Because atmospheric pressure and gravity induce the fluid to flow to the pump, a vented reservoir is located at the hydraulic system's highest point. A vent line draws air into the reservoir and exhausts it from there. A filter is frequently fitted in the vent pipe to prevent foreign material from entering the system.

Pressurized Reservoir

A pressurized reservoir is shut off from the atmosphere. This reservoir is pressurized either by engine bleed air or hydraulic pressure generated by the hydraulic system itself. Pressurized reservoirs are utilized on airplanes designed for high-altitude flights where atmospheric pressure is insufficient to force fluid flow to the pump.

An air pressure regulator determines the amount of air pressure in reservoirs pressured by engine bleed air, which is normally 10 to 15 pounds per square inch (psi).

Boeing-Vertol refers to this reservoir as a tank. It is made up of a metal housing with two internal pistons, one fixed and the other floating and sliding along a central tube. A bigger tube is attached to the floating piston and protrude through the tank's forward end, calibrated to indicate FULL and REFILL fluid levels for ramp-up and ramp-down positions, respectively.

HYDRAULIC ACCUMULATOR

A hydraulic accumulator is a pressure storage reservoir that holds a non-compressible hydraulic fluid under pressure generated by an external source of mechanical energy. An motor, a spring, a lifted weight, or pressurized gas can all serve as the external source. An accumulator allows a hydraulic system to handle extremes of demand with a less powerful pump, respond faster to a momentary demand, and smooth out pulsations. It's a form of energy storage device.

Hydraulic accumulators can aid with any hydraulic task. They are adaptable, make your machine easier to use, secure your hydraulic system, improve the energy economy of hydraulic systems, and perform a variety of other functions.

BLADDER ACCUMULATOR

Bladder accumulators are made up of a welded or forged pressure vessel, an accumulator bladder, and fittings for the gas- and medium-side connections. In addition to the normal design, additional designs for specific purposes are possible, such as for very high discharge speeds and pressures.

HYDRAULIC MOTOR

A hydraulic motor is a mechanical actuator that uses hydraulic pressure and flow to produce torque and angular displacement (rotation). The hydraulic motor serves as the rotating counterpart to the hydraulic cylinder as a linear actuator. In general, the category of devices known as hydraulic motors has included those that run on hydropower (namely, water engines and water motors), but in today's terminology, the name usually refers more specifically to motors that use hydraulic fluid as part of closed hydraulic circuits in modern hydraulic machinery.

Radial Piston Motors

Radial piston motors are available in two basic types: Pistons pushing inward, and pistons pushing outward.

Pistons pushing inward

The crankshaft type (e.g. Staffa or SAI hydraulic motors) with a single cam and the pistons pushing inwards is basically an old design but is one which has extremely high starting torque characteristics. They are available in displacements from 40 cc/rev up to about 50 litres/rev but can sometimes be limited in power output. Crankshaft type radial piston motors are capable of running at "creep" speeds and some can run seamlessly up to 1500 rpm whilst offering virtually constant output torque characteristics. This makes them still the most versatile design.

The single-cam-type radial piston motor exists in many different designs itself. Usually the difference lies in the way the fluid is distributed to the different pistons or cylinders, and also the design of the cylinders themselves. Some motors have pistons attached to the cam using rods (much like in an internal combustion engine), while others employ floating "shoes", and even spherical contact telescopic cylinders like the Parker Denison Calzoni type. Each design has its own set of pros and cons, such as freewheeling ability, high volumetric efficiency, high reliability and so on.

Pistons pushing outward

Multi-lobe cam ring types (e.g. Black Bruin, Rexroth, Hägglunds Drives, Poclain, Rotary Power or Eaton Hydre-MAC type) have a cam ring with multiple lobes and the piston rollers push outward against the cam ring. This produces a very smooth output with high starting torque but they are often limited in the upper speed range. This type of motor is available in a very wide range from about 1 litre/rev to 250 litres/rev. These motors are particularly good on low speed applications and can develop very high power.

Gerotor Motors Or Orbital Motors

The gerotor motor is in essence a rotor with N-1 teeth, rotating off center in a rotor/stator with N teeth. Pressurized fluid is guided into the assembly using a (usually) axially placed plate-type distributor valve. Several different designs exist, such as the Geroller (internal or external rollers) and Nichols motors. Typically, the Gerotor motors are low-to-medium speed and medium-to-high torque.

Vane motors

A vane motor consists of a housing with an eccentric bore, in which runs a rotor with vanes in it that slide in and out. The force differential created by the unbalanced force of the pressurized fluid on the vanes causes the rotor to spin in one direction. A critical element in vane motor design is how the vane tips are machined at the contact point between vane tip and motor housing. Several types of "lip" designs are used, and the main objective is to provide a tight seal between the inside of the motor housing and the vane, and at the same time to minimize wear and metal-to-metal contact.

Gear motors

A gear motor (external gear) consists of two gears, the driven gear (attached to the output shaft by way of a key, etc.) and the idler gear. High pressure oil is ported into one side of the gears, where it flows around the periphery of the gears, between the gear tips and the wall housings in which it resides, to the outlet port. The gears then mesh, not allowing the oil from the outlet side to flow back to the inlet side. For lubrication, the gear motor uses a small amount of oil from the pressurized side of the gears, bleeds this through the (typically) hydrodynamic bearings, and vents the same oil either to the low pressure side of the gears, or through a dedicated drain port on the motor housing, which is usually connected to a line that vents the motor's case pressure to the system's reservoir. An especially positive attribute of the gear motor is that catastrophic breakdown is less common than in most other types of hydraulic motors. This is because the gears gradually wear down the housing and/or main bushings, reducing the volumetric efficiency of the motor gradually until it is all but useless. This often happens long before wear causes the unit to seize or break down.

HYDRAULIC LIFT BLOCK

This control blocks are designed for the complex and flexible requirements in the area of lifting technology. They are tailored solutions for lifting-lowering controls which are, depending on the control block, load-dependently, load-independently or proportionately controlled. Applications include, for example, scissor-lift platforms, small lift trucks and pallet trucks. The permissible load is secured by means of an integrated pressure relief valve. The 2/2 two-way pilot valve is equipped with manual emergency lowering with self-actuating reset. A built-in return valve prevents uncontrolled lowering. A measurement connection is provided for for easy pressure measurement. In addition, a flange connection of the block to an optionally deliverable connection plate is possible.
