unidirectional cylinder are widely used in Slovakia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed unidirectional cylinder for customers from Slovakia.

Introduction to unidirectional cylinder:

The unidirectional cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the unidirectional cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The unidirectional cylinder is basically composed of unidirectional cylinder and unidirectional cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

The material, shape and compression of the unidirectional cylinder seal have a great impact on the service life and work efficiency of the unidirectional cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

We can not just consider the price and ignore the quality when we purchase the unidirectional cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the unidirectional cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the unidirectional cylinder is not required.

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.

Answers to some questions about unidirectional cylinder:

What is the difference between single acting hydraulic cylinder and double acting hydraulic cylinder?
Single action hydraulic cylinder is a single direction force work, the return of the plunger depends on itself or the weight of the mechanism to return. The double acting hydraulic cylinder is mainly different from the extension and retraction of the piston (the thrust and tension of the saying), which are all operated by the action of liquid pressure.

What is the cause of the deep scratch of the cylinder?
The following reasons can cause the cylinder to be scratched. 1: Hydraulic oil containing particulate impurities into the hydraulic cylinder, these particulate impurities stuck between the piston rod and the guide ring (or stuck between the piston and the inner wall of the cylinder), when the piston movement in the cylinder will scratch the piston rod, the phenomenon of the inner wall of the cylinder, the more particles, the larger the scratch marks the deeper and more obvious. 2: The body of the cylinder itself. Due to assembly or design reasons, the coaxial error between the piston rod, piston, cylinder, guide ring and other parts is too large, or the cylinder, piston rod straightness error is too large, so that the piston rod and the guide ring interference between the cylinder, this mechanical interference will certainly lose the piston rod or cylinder wall.
