(Holland supporting cylinder,produced by Hengyu Hydraulic Cylinder Factory）

supporting cylinder are widely used in Holland，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed supporting cylinder for customers from Holland.

Introduction to supporting cylinder:

The internal leakage of the supporting cylinder should be prevented when the supporting cylinder is used. The internal leakage of supporting cylinder includes the leakage caused by excessive wear of supporting cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

Regular maintenance of the supporting cylinder includes: regular tightening, supporting cylinder fastening screws and gland screws, supporting cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the supporting cylinder once a year. Clean regularly, the supporting cylinder is cleaned every other year, and the seals are replaced while cleaning.

When purchasing the supporting cylinder, try to clarify the following parameters of the supporting cylinder: A. supporting cylinder diameter, rod diameter, stroke; B. Working pressure or supporting cylinder load; C. Working environment temperature; D. Working medium; E. Operating speed; F. Other parameters, such as connection form, mounting size, etc. In this way, the right supporting cylinder type can be found accurately and quickly.

When the supporting cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the supporting cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

Answers to some questions about supporting cylinder:

What type of seal is the cylinder of shaft 50?
You won't know the exact model until you take it apart. Oil seals have O, Y, Yx, KYx, U, UN, UHS, YA, St, Gray, Yamagata, Lei type, etc. It is difficult to know what kind of oil seal the designer chooses. Cylinder oil seal installation method: 1. Receive a fixed number of oil seals. 2. From receiving the oil seal to assembly, it must be kept clean. 3. Before assembly, check the oil seal and measure whether the size of each part of the oil seal is consistent with the size of the shaft and cavity. Before the oil seal is installed, the size of the shaft diameter should be clearly compared with the inner diameter of the oil seal. The inner cavity size should be suitable for the outer diameter width of the oil seal. Check the lip of the oil seal for damage.

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.
