servo hydraulic cylinder are widely used in France，because of simple structure and reliable operation，simple structure and reliable operation，excellent fatigue and impact resistance.So our company has designed servo hydraulic cylinder for customers from France.

Introduction to servo hydraulic cylinder:

Before purchasing the servo hydraulic cylinder, it is necessary to master the original information and design basis, mainly including: the use and working conditions of the machine; The structural characteristics, load conditions, stroke size and operation requirements of the working mechanism; The selected working pressure and flow of the hydraulic system; The reality of materials, fittings and processes; Relevant national standards and technical specifications, etc.

When the servo hydraulic cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the servo hydraulic cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The servo hydraulic cylinder should be vented: when the servo hydraulic cylinder is installed or parked for a long time to work again, the air will penetrate into the servo hydraulic cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the servo hydraulic cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the servo hydraulic cylinder, the oil is best entered and discharged from the highest point of the servo hydraulic cylinder. servo hydraulic cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

Piston servo hydraulic cylinder is widely used in hydraulic transmission. When the servo hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the servo hydraulic 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 servo hydraulic 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.

Answers to some questions about servo hydraulic cylinder:

What is the cause of the sound of the excavator arm cylinder?
Hydraulic excavator cylinder includes boom cylinder, bucket rod cylinder and bucket cylinder, four cylinders. The sound of boom cylinder may be the wear of hydraulic cylinder block bushing, piston rod bushing and shaft pin. The main reason: poor lubrication, followed by improper clearance in the assembly process. Countermeasures: (1) Strictly lubricate each shaft pin at least once every 8 hours when the excavator is initially used for 100 hours and under harsh conditions; In other working conditions, lubricate each pin at least once every 50 hours. (2) If the lubricating oil passage is found to be blocked, it must be stopped for rectification. (3) Require assembly, replacement of all parts of the shaft pin, bushing strictly comply with the assembly testing standards and operating procedures.

Why is there noise in the hydraulic cylinder of the excavator lift arm?
There is no noise of a normal cylinder, check whether the throttle is ringing, or the mechanical part connected with it is ringing, and the mechanical part can be greased. If it can't be ruled out, disconnect the cylinder from the mechanical part and act alone to see what the situation is.
