Ethiopia hydraulic cylinder,pushing cylinder manufacturer,pushing cylinder

(Ethiopia pushing cylinder,produced by Hebei Hengyu company）

pushing cylinder are widely used in Ethiopia，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed pushing cylinder for customers from Ethiopia.

Introduction to pushing cylinder:

Protection of the pushing cylinder surface: During the dismantling process, safety protection should be carried out on the pushing cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the pushing cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the pushing cylinder should be cleaned up in time.

The material of the sliding part of the pushing cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

The pressure of the sliding surface of the pushing cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the pushing cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

pushing cylinder seal leakage causes and countermeasures: a. Loose tie rod nut will cause leakage, tighten the tie rod nut according to the torque requirements of tie rod nut, test no leakage can continue to use. b. Pressure exceeding the limit will also cause leakage. Replace the pushing cylinder seal and re-tighten the tie rod nut to reduce the pressure to the nominal pressure range of the pushing cylinder. c. The pushing cylinder seal is extruded, if the O-ring is obviously extruded at the pushing cylinder seal, replace the pushing cylinder seal.

Answers to some questions about pushing cylinder:

How does the hydraulic solenoid valve realize that the cylinder stops at any position?
Use an O-type medium function solenoid directional valve, or use a Y-type solenoid directional valve and a hydraulically controlled check valve.

What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.
