(Dominica push and pull the cylinder,produced by Hengyu Hydraulic Co., Ltd）

push and pull the cylinder are widely used in Dominica，because of high work efficiency，excellent fatigue and impact resistance，smooth movement.So our company has designed push and pull the cylinder for customers from Dominica.

Introduction to push and pull the cylinder:

The push and pull the cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the push and pull the cylinder, bite. Elimination method: When installing the push and pull the cylinder, ensure that the axis position of the push and pull the cylinder is consistent with the direction of movement; Make the load borne by the push and pull the cylinder as far as possible through the push and pull the cylinder axis, to avoid the phenomenon of eccentricity.

When producing oil push and pull the cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

push and pull the cylinder buffer valve inspection and maintenance: For the valve buffer push and pull the cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

Under normal circumstances, the push and pull the cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the push and pull the cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the push and pull the cylinder and the end cover, the piston and the piston rod, the piston and the push and pull the cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the push and pull the cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.

Answers to some questions about push and pull the cylinder:

What is the reason for the hydraulic cylinder sticking out and not retracting?
There are two reasons: First, the problem with the seal, if there are two seals on the piston, the top seal is broken. Second, when the hydraulic pressure itself is designed, the rod cavity area is too small, so that the desired return force can not be achieved during the return trip. You can first check whether the coupling is damaged; Then see if the relief valve in the oil line block is blocked. If the use time is too long, it needs to be cleaned, the hydraulic oil is very dirty and can block oil block. Electromagnetic directional valves can also be checked, but the chance of problems is relatively small, unless there is a product problem.

What is the material of the lift cylinder?
The cylinder is composed of many parts. The cylinder also contains the seal and the installation port at both ends, the material of these two parts is not easy to determine if there is no physical object. The cylinder body is generally 20 steel, 45 steel, 27SiMn and other materials, and the piston rod is generally 40Cr, 45 steel and other materials.
