(UAE non-standard special type cylinder,produced by Hengyu Hydraulic Cylinder Factory）

non-standard special type cylinder are widely used in UAE，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed non-standard special type cylinder for customers from UAE.

Introduction to non-standard special type cylinder:

When the non-standard special type 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 non-standard special type 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.

If the non-standard special type cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the non-standard special type cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow non-standard special type cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the non-standard special type cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the non-standard special type cylinder includes the leakage caused by excessive wear of the non-standard special type cylinder block seal, the piston rod and the seal cover seal and the piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and non-standard special type cylinder, and the phenomenon of "pulling the non-standard special type cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

The repair method of the non-standard special type cylinder: the repair of the non-standard special type cylinder must use brush plating. This is because this repair method can be carried out on site, and the repair effect is good. In this way, loading and transportation can be eliminated to shorten the repair time and improve work efficiency. In addition, the coating obtained by brush plating has good binding force and will not have obvious boundaries. Moreover, the repair surface has high hardness and good wear resistance.

The coordination of the sliding parts of the non-standard special type cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

Answers to some questions about non-standard special type cylinder:

How to distinguish high pressure cylinder and low pressure cylinder?
There is no special definition of the cylinder, the so-called pressure classification refers to the pump low pressure (code L) container 0.1MPa ≤p < 1.6MPa; Medium pressure (code M) container 1.6MPa ≤p < 10.0MPa; High pressure (code H) vessel 10 MPa≤p < 100 MPa; Ultra-high pressure (code U) container p≥100MPa. (1MPa=9.8Kg)

How many tons is the oil cylinder 16mpa?
It depends on the cross-sectional area of the cylinder A(mm2)F=16mpa×A unit is (tons).
