(Holland shearing machine cylinder,produced by Hengyu Group）

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

Introduction to shearing machine cylinder:

The method of sleeve shearing machine cylinder to improve the processing quality: there is a big gap in the service life of post-plating polishing and post-plating polishing, especially in mass production. Strictly clean the flying edge and burr of mechanical components, especially the edge of the sealing groove, and the tiny metal burr, strictly clean before assembly. The surface fatigue strength and stress corrosion resistance of the shearing machine cylinder can be significantly improved by rolling in the finishing of the inner holes of the shearing machine cylinder. The roughness of the surface of the friction pair is generally controlled between Ra0.4 and 0.8.

Before the shearing machine cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

Piston shearing machine cylinder is widely used in hydraulic transmission. When the shearing machine cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the shearing machine cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the shearing machine cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

When the shearing machine cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the shearing machine cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the shearing machine cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the shearing machine cylinder can meet the requirements by grinding. However, the life and reliability of this repair shearing machine cylinder are not high.

Answers to some questions about shearing machine cylinder:

Loader arm fell badly, how to know which oil cylinder is leaking?
No matter which cylinder leakage the arm will drop, it is best to replace the oil seal, even if one cylinder is good, it will not last long, and it will drop the arm, so the two cylinders should be replaced at once.

How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.
