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

Introduction to steering power cylinder:

Because of the slightly complex structure of the buffer steering power cylinder, sometimes there will be problems, such as when the steering power cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

steering power cylinder hydraulic oil selection: The recommended working oil viscosity of the steering power cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

If the steering power cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

When the piston speed of the steering power cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the steering power cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

Answers to some questions about steering power cylinder:

What should we pay attention to when using the cylinder?
When using the cylinder, we should pay attention to the environment and temperature in which it is located as follows: 1. Before working, the hydraulic cylinder must carry out several reciprocating movements under low pressure (greater than the starting pressure), and work normally after removing the gas in the cylinder. 2. Precautions when removing the hydraulic cylinder: ① The pressure in the hydraulic circuit is reduced to zero before disassembly. ② The screw thread at the top of the piston rod should be prevented from damage when disassembling. ③ Due to the different structure and size of the hydraulic cylinder, the order of disassembly is also slightly different. Generally, the fastening bolt of the end cover should be loosened first. Internal card chain card key application special tools.

What material is the piston rod of the cylinder made of?
About the piston rod: ① Piston rods are usually made of 45# steel. When there is a large impact force and heavy load transmission, it is made of 40Cr steel. This is to ensure that the piston rod has sufficient working strength. ② The piston rod is generally designed as a cylinder, if the diameter is larger, the hollow piston rod can be used with 45# seamless steel pipe. ③ When the piston rod is manufactured, the blank should be first forged and conditioned after mechanical rough processing, and the hardness of HB=230 ~ 250. The purpose of conditioning is to improve the machining performance and increase the working strength of the material. ④ The surface roughness Ra of the piston rod after finishing should not be greater than 0.65μm. ⑤ In order to improve the corrosion resistance of the piston rod, the rod surface needs to be chrome plated.
