Qatar hydraulic cylinder,supporting cylinder manufacturer,supporting cylinder

(Qatar supporting cylinder,produced by Hebei Hengyu company）

supporting 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 supporting cylinder for customers from Qatar.

Introduction to supporting cylinder:

supporting cylinder installation precautions: Before installing the supporting cylinder into the system, the parameters on the supporting cylinder label should be compared with the parameters when ordering. The base of the supporting cylinder must have sufficient stiffness, otherwise the supporting cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

supporting cylinder can not drive the load troubleshooting: oil pressure is too low. supporting cylinder selection specifications are too small. Leakage in supporting cylinder or associated hydraulic system element.

The body of the supporting cylinder on the processing process requirements: the body of the supporting cylinder is an important and essential part of the supporting cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the supporting cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

When the supporting 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 supporting 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.

Answers to some questions about supporting cylinder:

Why are the hydraulic cylinders out of sync? The reasons for the unsynchronous operation are as follows: 1, the deviation of the external load of the two cylinders, such as the different resistance and friction of the two cylinders will lead to imbalance. The displacement of the cylinder with low resistance will be larger. 2, the difference in internal friction, such as the difference between the piston and the cylinder of each cylinder, the friction between the piston rod and the seal causes the cylinder to be out of sync. 3. The different resistance of hydraulic oil along the pipeline of the two cylinders causes the cylinder to be out of sync. 4, the deviation of the control original adjustment causes the deviation of the flow to be out of sync, such as the use of an independent throttle valve for each cylinder will appear the difference in the flow of oil in and out of the oil affecting the synchronization of the two cylinders. 5. The cylinder support point of the supported part is initially different.

Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.
