(Qatar hoister hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to hoister hydraulic cylinder:

When the hoister hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the hoister hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

The "O" ring can be used as an auxiliary seal inside the hoister hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the hoister hydraulic cylinder, and can be completely sealed.

In use, the hoister hydraulic 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 hoister hydraulic cylinder.

How to repair the hoister hydraulic cylinder body when it is damaged: When the hoister hydraulic cylinder has trace deformation and shallow tensile marks, the hoister hydraulic cylinder is repaired by strong honing process. The heavy honing process can repair hoister hydraulic cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the hoister hydraulic cylinder can meet the technical requirements.

Answers to some questions about hoister hydraulic cylinder:

How is the hydraulic cylinder selected in the mechanical design manual?
First of all, it is necessary to meet your work needs, and the second is to meet the structural space of the cylinder and accessories. Three to consider the other parameters of the cylinder.

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
