(Bulgaria steering cylinder,produced by Hebei Hengyu company）

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

Introduction to steering cylinder:

When installing the steering cylinder, the axial ends of the steering cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the steering cylinder, there is axial expansion. If the two ends of the steering cylinder are fixed, all parts of the steering cylinder will be deformed. When disassembling the steering cylinder, it is strictly forbidden to hammer the steering cylinder and the piston surface, such as the steering cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

The steering cylinder requires that the filtration accuracy of the system is not less than the 80um, and the oil pollution should be strictly controlled, the oil should be kept clean, the performance of the oil should be checked regularly, and the necessary fine filtration and replacement of new working oil should be carried out.

The steering cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the steering cylinder, bite. Elimination method: When installing the steering cylinder, ensure that the axis position of the steering cylinder is consistent with the direction of movement; Make the load borne by the steering cylinder as far as possible through the steering cylinder axis, to avoid the phenomenon of eccentricity.

The difference between the plunger steering cylinder and the piston steering cylinder is that the piston in the steering cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type steering cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about steering cylinder:

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.

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.
