(Bulgaria spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Bulgaria，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed spring return cylinder for customers from Bulgaria.

Introduction to spring return cylinder:

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

If the seal of the spring return 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.

In order to ensure the service life of the spring return cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

When purchasing the spring return cylinder, try to clarify the following parameters of the spring return cylinder: A. spring return cylinder diameter, rod diameter, stroke; B. Working pressure or spring return 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 spring return cylinder type can be found accurately and quickly.

Answers to some questions about spring return cylinder:

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.

What is the HS code of the hydraulic cylinder?
