(Spain roller press hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

roller press hydraulic cylinder are widely used in Spain，because of no transmission clearance，simple structure and reliable operation，excellent temperature resistance.So our company has designed roller press hydraulic cylinder for customers from Spain.

Introduction to roller press hydraulic cylinder:

roller press hydraulic cylinder installation precautions: Before installing the roller press hydraulic cylinder into the system, the parameters on the roller press hydraulic cylinder label should be compared with the parameters when ordering. The base of the roller press hydraulic cylinder must have sufficient stiffness, otherwise the roller press hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The roller press hydraulic 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.

If the roller press hydraulic cylinder slips or crawls, please check whether there is astringency inside the roller press hydraulic cylinder, because the internal parts of the roller press hydraulic 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 roller press hydraulic 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 roller press hydraulic 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.

We can not just consider the price and ignore the quality when we purchase the roller press hydraulic cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the roller press hydraulic cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the roller press hydraulic cylinder is not required.

Answers to some questions about roller press hydraulic cylinder:

What welding rod is used for hydraulic cylinder welding?
There are several reasons for bad welding of hydraulic cylinder: 1. There is hydraulic oil on the welding surface, wipe it with a rag, there will be bubbles in the welding process, and it will not last for a few days. You have to remove it, drain it, wash it off with gasoline and try again. 2. Open the groove before welding, it is not deep enough to use the Angle grinding machine, and can not find the accurate crack position. 3. The material of the cylinder itself is not clear, the welding performance of more than 35 steel is not good, in the factory welding needs to preheat, the welding rod should also be dried and insulated, there is no such condition on the site.

Does the excavator use a hydraulic cylinder?
First, construction machinery is generally a hydraulic cylinder. Second, hydraulic transmission equipment is usually composed of four components, power, execution, control and auxiliary. And the hydraulic cylinder as a linear reciprocating motion or less than 360. Reciprocating motion of the hydraulic mechanism, simple structure, reliable work, is also widely used in the hydraulic system of the main actuator, it is the prime mover in the form of mechanical energy to drive the hydraulic pump produced by the liquid pressure energy, and then can be directly driven load for reciprocating movement or less than 360.
