(Qatar spring return cylinder,produced by Hengyu Hydraulic Co., Ltd）

spring return cylinder are widely used in Qatar，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed spring return cylinder for customers from Qatar.

Introduction to spring return cylinder:

In order to ensure the service life of the spring return cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the spring return cylinder, causing damage to the seal and causing leakage in the spring return cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

The spring return cylinder pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.

After chrome plating of the piston rod of the spring return cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

Disassembly spring return cylinder: When disassembly spring return cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the spring return cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the spring return cylinder.

Answers to some questions about spring return cylinder:

What is the pressure provided for a 63-bore cylinder with a pressure of 2 mpa?
2 mpa pressure is equivalent to 20 kg per square centimeter, 6.3 cm straight longitude, 3.15 cm radius, square, multiplied by, calculated an area of about 31.5 square centimeters, multiplied by 20 kg, the pressure is about 630 kg.

How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.
