If the piston rod of the hydraulic cylinder is not treated in time after being pulled, the normal use will be affected if it is light, and the operation will not be possible if it is heavy. The repair methods we adopt are local polishing to repair light draw marks, welding and manual polishing to repair heavy draw marks. Shenyang Hydraulic cylinder Through quenching and tempering treatment, the comprehensive mechanical properties of the cylinder piston rod with good strength and toughness matching were obtained. Shenyang Hydraulic cylinder Manufacturer The purpose of surface hardening is to obtain high surface hardness to support the chromium plating layer on the surface, so as to improve the wear resistance and corrosion resistance of the piston rod.

As the structure and size of various hydraulic cylinders are different, the disassembly sequence is slightly different. Generally, drain the oil in the two chambers of the oil cylinder, remove the cylinder head, and finally remove the piston and piston rod. Shenyang Hydraulic cylinder When disassembling the cylinder head of the hydraulic cylinder, special tools shall be used for the key or snap ring of the internal key type connection, and flat shovel is prohibited; Flange end caps must be pushed out with screws, and hammering or hard prying is not allowed. When it is difficult to draw out the piston and piston rod, do not force them out, Shenyang Hydraulic cylinder Manufacturer The reason shall be found out before disassembly. Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being polluted by the surrounding dust and impurities.

Two way hydraulic cylinder, which is one of the hydraulic cylinders, is a common and commonly used type of hydraulic cylinder. Therefore, Shenyang Hydraulic cylinder Manufacturer It is necessary to have a correct understanding of this kind of hydraulic cylinder and have a certain understanding, so that we can know how to use it reasonably and make full use of it. This kind of hydraulic cylinder has corresponding operation regulations and maintenance regulations, because it is in the hydraulic cylinder category. In addition, Shenyang Hydraulic cylinder It is necessary to have a clear and comprehensive understanding of its operation and maintenance procedures. The symptom of strain and wear is that the lifting speed of the equipment is relatively slow, accompanied by self subsidence.

Hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion (or swing motion). It is simple in structure and reliable in operation. When it is used to realize reciprocating movement, the reducer can be avoided, Shenyang Hydraulic cylinder And there is no transmission clearance, smooth movement, so it is widely used in various mechanical hydraulic systems. Output force of the hydraulic cylinder is proportional to effective area of the piston and pressure difference on both sides; The hydraulic cylinder basically consists of cylinder barrel, cylinder head Shenyang Hydraulic cylinder Manufacturer The piston and piston rod, sealing device, buffer device and exhaust device are composed.
