Singapore hydraulic cylinder,retractable cylinder manufacturer,retractable cylinder

(Singapore retractable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

retractable cylinder are widely used in Singapore，because of no need for deceleration device，long service life，smooth movement.So our company has designed retractable cylinder for customers from Singapore.

Introduction to retractable cylinder:

When producing oil retractable cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.

The difference between the plunger retractable cylinder and the piston retractable cylinder is that the piston in the retractable 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 retractable cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

If the seal of the retractable cylinder is softened and sticky, it may be that the seal is incompatible with the hydraulic oil or the nearby lubricating oil, replace the appropriate seal; If the seal becomes hard and loses elasticity, most of it is because the ambient temperature is too high (more than 80 ° C), make appropriate temperature insulation protection or replace the high temperature seal.

When the retractable cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the retractable cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil retractable cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical retractable cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the retractable cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Answers to some questions about retractable cylinder:

What is hydraulic cylinder guide?
The cylinder itself can not move, the piston moves, the guide should be used to guide the mechanism connected with the piston extension end. For example, in the commonly used hydraulic press, the guide column above is used to guide the pressure plate connected with the piston.

Why does the hydraulic cylinder go up to the top and then slowly go down?
Leakage in the cylinder or the hydraulic valve that controls the cylinder, can be replaced and removed. Or add a pressure retaining valve to the hydraulic system to ensure pressure.
