Cameroon hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder

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

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

Introduction to supporting cylinder:

When the supporting cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the supporting cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

If the supporting cylinder slips or crawls, please check whether there is astringency inside the supporting cylinder, because the internal parts of the supporting cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the supporting cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the supporting cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

How the cavitation of the supporting cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the supporting cylinder, resulting in corrosive damage to the parts.

supporting cylinder body inspection: The inner surface of the supporting cylinder and the piston seal are the main factors causing the leakage in the supporting cylinder, if the supporting cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the supporting cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Answers to some questions about supporting cylinder:

Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.

How to control the speed of the cylinder?
High demand control, it is necessary to use servo closed-loop control, you can adjust the speed at will. Reference: Hydrodynamic Motion Control Practical Design Guide.
