(Puerto Rico trailer hydraulic cylinder,produced by Hengyu Group)

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

Introduction to trailer hydraulic cylinder:

After the trailer hydraulic cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

Improve the service life of the trailer hydraulic cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the trailer hydraulic cylinder (such as the trailer hydraulic cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the trailer hydraulic cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the trailer hydraulic cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single trailer hydraulic cylinder exhaust.

When the trailer 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 trailer 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 scar on the sliding surface of the trailer hydraulic cylinder piston will transfer with use. Before the piston is installed, there are scars on its sliding surface, which are installed intact and untreated, and these scars will in turn scratch the inner surface of the trailer hydraulic cylinder wall. Therefore, before installation, these scars must be fully repaired.

Answers to some questions about trailer hydraulic cylinder:

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.
