(Czech Republic unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Czech Republic，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed unidirectional cylinder for customers from Czech Republic.

Introduction to unidirectional cylinder:

Disassembly unidirectional cylinder: When disassembly unidirectional cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the unidirectional cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the unidirectional cylinder.

When the long-stroke unidirectional cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in unidirectional cylinder head seal damage, oil leakage, and piston sleep in the unidirectional cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the unidirectional cylinder; The piston and the piston rod are connected with a spherical joint.

unidirectional cylinder use should try to avoid sealing belt into the unidirectional cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the unidirectional cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the unidirectional cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

When the unidirectional cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the unidirectional cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the unidirectional cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about unidirectional cylinder:

How to set the stroke of the cylinder?
Self-design should be based on product demand and practical application. The stroke of standard cylinder depends on the parameters the customer requires. The hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of the hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the speed and force of the linear motion. The piston of the hydraulic cylinder can complete the linear reciprocating movement, and the linear displacement of the output is limited. Hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy of reciprocating linear motion. The hydraulic cylinder is basically composed of cylinder body, cylinder head, piston and piston rod, sealing device, buffer device and exhaust device.

How does the clamping cylinder work?
Hydraulic transmission principle: oil as the working medium, through the change of the sealing volume to transfer movement, through the internal pressure of the oil to transfer power. 1. The power part - converts the mechanical energy of the prime mover into the pressure energy of the oil (hydraulic energy). For example: hydraulic pump. 2, The executive part - the hydraulic pump input oil pressure energy into the mechanical energy to drive the working mechanism. For example: hydraulic cylinder, hydraulic motor. 3, The control part - used to control and adjust the oil pressure, flow and flow direction. For example: pressure control valve, flow control valve and direction control valve. 4, The auxiliary part - the first three parts are connected together to form a system, which plays the role of oil storage, filtration, measurement and sealing.
