Korea pushing cylinder

(Korea pushing cylinder,produced by Hengyu Group)

pushing cylinder are widely used in Korea,because of simple structure and reliable operation,excellent temperature resistance,no transmission clearance.So our company has designed pushing cylinder for customers from Korea.

Introduction to pushing cylinder:

In use, the pushing cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the pushing cylinder.

How the cavitation of the pushing cylinder is formed: With the gradual rise of pressure, the gas in the oil will become bubbles, when the pressure rises to a certain limit value, these bubbles will break under the action of high pressure, so that the high temperature and high pressure gas will quickly act on the surface of the parts, resulting in cavitation of the pushing cylinder, resulting in corrosive damage to the parts.

The pushing cylinder is mainly composed of body, piston, piston rod, pushing cylinder head, pushing cylinder bottom, piston rod head and related auxiliary devices. The piston divides the pushing cylinder into two chambers, and moves reciprocally in the pushing cylinder with the help of pressure oil. In order to improve its working effect, there is no sealing ring on the piston to eliminate internal leakage, where the piston rod passes through the pushing cylinder head, due to the existence of the gap, it is easy to produce external leakage phenomenon, and the dust can enter the pushing cylinder through the gap, so the sealing device and dust prevention reason are set. At the same time, in order to eliminate the influence of eccentric load on the work of the piston, all the pushing cylinders must be provided with a considerable length of guide sleeve at the extended end of the piston rod. In addition, in the case of faster piston movement, the phenomenon of mechanical collision between the piston and the pushing cylinder bottom and the pushing cylinder head is serious, so the buffer deceleration should be set at both ends of the pushing cylinder The working medium of the pushing cylinder: because it works at room temperature, the ordinary oil-type hydraulic oil can be selected; pushing cylinder sealing device: The use of Yx sealing ring, polyurethane (PU) and polytetrafluoroethylene (PTFE) materials combined to achieve a good sealing effect; Buffer mechanism of the pushing cylinder: The buffer structure of the pushing cylinder is to prevent the piston from colliding with the pushing cylinder head at the end of the stroke.

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.

Answers to some questions about pushing cylinder:

How to calculate multistage cylinder volume?
When the multi-stage cylinder is extended, the largest cylinder is extended first, and when the largest cylinder stroke is completed, the second largest cylinder is extended again, the second largest cylinder stroke is completed, the third largest cylinder is extended again... Therefore, the cylinder extension length is less than the stroke of the largest cylinder, and the volume is the extension length times the inner hole area of the largest cylinder. The cylinder extension length is greater than the maximum cylinder stroke and less than (the largest cylinder stroke + the second largest cylinder stroke), and the volume is the largest cylinder stroke times the internal hole area of the largest cylinder + (the extension length - the largest cylinder stroke) times the second largest cylinder.

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
