(Bulgaria metallurgical cylinder,produced by Hengyu Hydraulic Cylinder Factory）

metallurgical cylinder are widely used in Bulgaria，because of long service life，smooth movement，high work efficiency.So our company has designed metallurgical cylinder for customers from Bulgaria.

Introduction to metallurgical cylinder:

metallurgical cylinder buffer valve inspection and maintenance: For the valve buffer metallurgical cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

The main role of the metallurgical cylinder: the metallurgical cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the metallurgical cylinder realizes reciprocating motion. The structure of the metallurgical cylinder has three categories: piston metallurgical cylinder, plunger metallurgical cylinder, swing metallurgical cylinder, piston metallurgical cylinder and plunger metallurgical cylinder to achieve reciprocating linear motion, output speed and thrust, swing metallurgical cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the metallurgical cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The metallurgical cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

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

If the seal of the metallurgical 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.

Answers to some questions about metallurgical cylinder:

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.

What is the material of the cylinder support ring?
Generally, it is polytetrafluoroethylene doped with copper powder, or polyformaldehyde, and copper sleeves, there are also nylon, resin and so on.
