(Singapore boarding axle cylinder,produced by Hebei Hengyu company）

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

Introduction to boarding axle cylinder:

How to repair the boarding axle cylinder body when it is damaged: When the boarding axle cylinder has trace deformation and shallow tensile marks, the boarding axle cylinder is repaired by strong honing process. The heavy honing process can repair boarding axle 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 boarding axle cylinder can meet the technical requirements.

When the boarding axle cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the boarding axle cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

The internal leakage of the boarding axle cylinder should be prevented when the boarding axle cylinder is used. The internal leakage of boarding axle cylinder includes the leakage caused by excessive wear of boarding axle cylinder block seal, piston rod and seal cover seal and 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.

boarding axle cylinder hydraulic oil selection: The recommended working oil viscosity of the boarding axle cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

Answers to some questions about boarding axle cylinder:

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.

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.
