(Angola steering cylinder,produced by Hebei Hengyu company）

steering cylinder are widely used in Angola，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed steering cylinder for customers from Angola.

Introduction to steering cylinder:

The difference between the integral steering cylinder and the split steering cylinder: The integral steering cylinder and the split steering cylinder in the steering cylinder are two different steering cylinders, and they are very different. The whole steering cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split steering cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and steering cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

When the steering cylinder is in use, ensure that the steering cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

After chrome plating of the piston rod of the steering cylinder, the surface flatness is not fully treated: After chrome plating of the piston rod surface, the method of post-plating polishing should be changed to post-plating polishing. Although it is necessary to increase the thickness of the coating before grinding (generally increased by about 0.02 in the diameter direction), it can remove chrome plating defects well, and test the binding force of the coating. In addition, due to the micro-roughness of the grinding surface, the trough can store lubricating oil, which can improve the wear resistance and extend the service life.

steering cylinder buffer valve inspection and maintenance: For the valve buffer steering 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.

Answers to some questions about steering cylinder:

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.
