The working principle of single-acting cylinders are to transfer hydraulic fluids or an output force in one direction only. Within the cylinder, the piston rod can push outwards but cannot pull back, therefore requiring a force in the opposite direction to return the rod back to its original position.
A double-acting hydraulic cylinder has a port at each end, supplied with hydraulic fluid for both the retraction and extension of the piston. A double-acting cylinder is used where an external force is not available to retract the piston or it can be used where high force is required in both directions of travel.
Telescopic cylinders are used when an application requires a compact retracted dimension, but needs a longer stroke. These cylinders are generally single acting and are available in two to five stages. Common mounting options for telescopic cylinders are trunnion and cross-tube.
Tie-rod cylinders are most often used in industrial applications. They use high strength, threaded steel rods and nuts to hold square or rectangular end caps to each end of the cylinder barrel. Seals are placed between the barrel and end cap to prevent leakage.
Welded hydraulic cylinders have no tie rods. Instead, the barrel is welded directly to the end caps and the ports are welded to the barrel. The front rod gland is generally bolted or threaded into the cylinder barrel, which allows the piston rod assembly and the rod seals to be removed for service.
Mill – Type are cylinders designed to fill a need for a more durable, more reliable product to reduce down-time and maintenance costs.
Trunnion mounted cylinders are heavy duty pivoting cylinders with pintles mounted to the head, cap or intermediate position. Although superior to clevis or pivot mounted cylinders, they may still require stop tubes in long stroke applications.
A hydraulic power unit utilizes fluid to transmit power from one place to another and it is used to apply hydraulic pressure to power the hydraulic motors. Power packs are often used for heavy lifting applications or anything that requires strong, directional force. They are mainly used for industrial applications. Such hydraulic power packs create huge power and high flow rates. They can handle heavy loads for a long period.
DC Hydraulic mini power packs which cover 12volt / 24volt DC, with a flow range from 1cc to 5 cc. We supply DC Power packs with temperature protector and multiple options of valve configuration that suit the applications.
The main function of the gland is to enclose the pressure chamber from the other end. It is the end cap through which the rod extends from the cylinder tube. The gland has seals for the rod and the tube of the cylinder as well. The piston is attached to the piston rod and moves up and down through the cylinder bore, pushed by the hydraulic fluid. It provides the area used to create the hydraulic force.
A hydraulic manifolds which reduces piping and regulates fluid flow between pumps and actuators and other components in a hydraulic system. It is like a switchboard in an electrical circuit because it lets the operator control how much fluid flows between which components of a hydraulic machinery.
The Hydraulic Bell Housing is designed for coupling hydraulic pumps having flanges to electric motors having metric flanges. These bell housings are precisely machined to reduce misalignment of coupled shafts.
A hydraulic cylinder tube with finished ID is to be referred as Honed Tube.One of the most important materials for manufacturing hydraulic cylinders are Honed Tube.
The materials and coating of the hydraulic cylinder is utmost important. Most commonly, the cylinder rod is made of steel or stainless steel and is then coated with Hard Chrome Plating.
Micro Hose Test Assemblies and Test Point fittings let you test systems at working pressures without tools and check for leaks in multiple spots. They are ideal for hydraulic oils and other mineral-based fluids used in off-road mobile equipment.
Gear pumps are commonly used for pumping high viscosity Oil fluids. They are preferred in any application where accurate dosing or high-pressure output is required.
Compact heavy-duty pumps designed for Industrial / Mobile applications like operating small presses, and fixtures, as well as providing source of oil for hydraulically operated emergency equipments.
A hydraulic tandem gear pump uses SP gears, with small fluctuation, high pressure, low noise and stable performance. A hydraulic tandem gear pump uses composite material bearings and high-performance sealing elements has a small starting torque and good tightness and can work efficiently under harsh working conditions.
They are suitable for pumping low viscosity fluids. These pumps improve flow rate by reducing the internal mechanical losses and damping. An electric motor is coupled to the pump rotor to create a rotary motion. As the rotor rotates, the fluid enters the pump. This fluid flows into the hydraulic vane pump chambers. The volume of the vane chambers at the inlet sections is larger than that at the outlet section of the pump. The decrease in volume helps the fluid to develop a high pressure as it exits the pump. As the rotor rotates, the pump vanes tend to move outwards. This is due to the centrifugal force and the symmetrical shape of the pump casing. In the inlet, the vanes create a vacuum, causing a pressure difference thus, it draws fluid into the pump.
Plunger pumps can be found as reliable high-pressure pumps in many industrial applications. Displacement pumps are suitable for small or large flow rates and achieve different pressure levels. Can handle much fluid pressure.
Variable displacement pumps used in hydraulic applications can have variable flow rate, consume less energy, be operated with high accuracy for slow and rapid motion, generate more heat. The displacement or amount of fluid pumped per revolution of the pump’s input shaft can be varied while the pump is running.
These pumps use their contracting and expanding cavities to move hydraulic fluids from the cylinder to the tubes. This is possible with the help of an electric motor that creates motion, pistons and check valves. The pistons exert pressure on the fluid while the check valves ensure the fluid flows in the right direction. Oil immersed type, open execution, face mounting, valve controlled, fixed delivery, bi-directional rotation of the shaft.
Directional control valves are used to control the direction and movement of hydraulic fluid through a system. They are often referred to as switching valves and come in three main categories: hydraulic check valves, directional spool valves and poppet valves that make up the different types of control valves.
Check valves are the simplest form of hydraulic devices in that they permit free oil flow in one direction and block oil flow in the opposite direction. Check valves may also be used as a directional or pressure control in a hydraulic system.
Poppet valves are used in hydraulic systems. They are commonly controlled through solenoids and can be set to be either normally-closed or normally-open in their de-energized states. They are also used as check valves to provide one-way flow and as relief valves to guard against over pressure.
Monoblock: Have many outstanding features including high performance, high efficiency, small volume, mass flow, and leak proof. In addition, the compact direction control valves have fixed and big pull rods to control direction, providing various ports and circuit valves.
Sectional: Offers multi-function control valve method to solve hydraulic circuit system requirement. The compact construction design is one of strong features for sectional directional control valves include other features, such as low pressure drop high efficiency.
A hydraulic solenoid valve is a solenoid-controlled directional valve used in a hydraulic system for opening & closing or changing the direction of flow of the liquid. The valve operates with a solenoid, which is an electric coil wound around a ferromagnetic core at its centre.
A hydraulic manual directional valve used in hydraulic system for opening & closing or changing the direction of flow of the liquid.
Pressure relief valves are used in hydraulic systems to limit the system pressure to a specific set level. If this set level is reached, the pressure relief valve responds and feeds the excess flow from the system back to the tank.
The purpose of pressure-reducing values is to keep the secondary pressures correct in branches of hydraulic systems. Most pressure-reducing valves are open and 2 way this allows the pressure to flow freely until they reach further downstream where there is a set pressure.
Counterbalance valves are used in hydraulic systems working with an overriding (run-away) or suspended load. They are designed to create back pressure at the return line of the actuator to prevent losing control over the load.
Unloading valves are used in hydraulic circuits, these valves would stop or remove the flow of the pump back to the tank when the machine is not operating. So by this reduction of heat and energy saving can be achieved because the prime mover load is reduced.
The purpose of a flow control valve is to regulate the flow rate in a specific portion of a hydraulic circuit. In hydraulic systems, they’re used to control the flow rate to motors and cylinders, thereby regulating the speed of those components.
A needle valve is used to accurately control flow rates of clean fluids. The adjustments are gradual and smooth for controlling the flow rate.
Allow hydraulic oil into different paths from one or more sources. Will usually consist of a spool inside a cylinder which is mechanically or electrically actuated. The position of the spool restricts or permits flow, thus it controls the fluid flow.
Designed to control double pumps of a Hi-Low system. It unloads a low-pressure pump when system pressure rises above-set pressures and only high-pressure pump delivers the flow. Nominal flow and pressure ratings model max (Check Models).
Prefill valve is a drain valve which drains oil between the cylinder and tank. The prefill valve prevents the oil from flowing from the Hydraulic cylinder to the main tank while pressurizing inversely the hydraulic cylinder will make oil drain to the tank when reversion.
A pressure switch is an instrument that automatically senses a change in pressure and opens or closes an electrical switching element, when a predetermined pressure point is reached. A pressure-sensing element is that part of a pressure switch that moves due to the change in pressure.
A non-return valve allows a medium to flow in only one direction and is fitted to ensure that the medium flows through a pipe in the right direction, where pressure conditions may otherwise cause reversed flow.
A hydraulic motor is a mechanical actuator that converts hydraulic pressure and flows into torque and angular displacement (rotation). The hydraulic motor is the rotary counterpart of the hydraulic system.
Hydraulic seals are gasket-like rings that are designed to seal areas between the components in a hydraulic cylinder. Hydraulic cylinders contain many different components, some of which are exposed to the fluid. To prevent fluid from leaking around these components, hydraulic seals are used. Hydraulic seals are designed to fit the components in a hydraulic cylinder while creating a leak-proof seal around them.
O-rings are used to seal all kinds of devices to keep them operating and safe. They do so by keeping necessary fluids in hydraulic systems and unwanted fluids and contaminants out.
Hydraulic fittings connect conductors such as hoses, pipes and tubes in a hydraulic system. Most fittings have a male and female component. that joins to form a connection. These connections help contain and direct the flow of hydraulic fluid in the conductor while preventing leaks and maintaining pressure.
The fitting is more resistant and varies based on their sizes, configuration and thread types. A high level of accuracy maintained as it is produced using CNC machines.
