Czech Republic hydraulic cylinder,series synchronous cylinder manufacturer,series synchronous cylinder

(Czech Republic series synchronous cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to series synchronous cylinder:

The difference between the integral series synchronous cylinder and the split series synchronous cylinder: The integral series synchronous cylinder and the split series synchronous cylinder in the series synchronous cylinder are two different series synchronous cylinders, and they are very different. The whole series synchronous cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split series synchronous cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and series synchronous cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

If the seal of the series synchronous cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

If the series synchronous cylinder slips or crawls, please check whether there is astringency inside the series synchronous cylinder, because the internal parts of the series synchronous 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 series synchronous 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 series synchronous 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.

The wear of the hard chromium plating layer of the series synchronous cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

Answers to some questions about series synchronous cylinder:

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.

How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.
