(Japan stern plate hydraulic cylinder,produced by Hengyu Group）

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

Introduction to stern plate hydraulic cylinder:

At the rated pressure, the thrust of the stern plate hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the stern plate hydraulic cylinder is related to the diameter of the stern plate hydraulic cylinder, but not to the stroke of the stern plate hydraulic cylinder. Moreover, the larger the stern plate hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the stern plate hydraulic cylinder.

stern plate hydraulic cylinder spool stuck or valve hole blocked How to solve: When the flow valve or direction valve spool stuck or valve hole blocked, the stern plate hydraulic cylinder prone to misoperation or action 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 the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium.

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

The piston rod and guide sleeve function of the stern plate hydraulic cylinder is crucial: the relative motion pair between the piston rod and the guide sleeve is the main factor causing external leakage, if the chrome layer on the surface of the piston rod is spalling or producing longitudinal tensile marks due to wear, it will directly lead to the failure of the seal.

Answers to some questions about stern plate hydraulic cylinder:

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.

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.
