Ireland hydraulic cylinder,stern plate hydraulic cylinder manufacturer,stern plate hydraulic cylinder(Ireland stern plate hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
stern plate hydraulic cylinder are widely used in Ireland,because of long service life,smooth movement,high work efficiency.So our company has designed stern plate hydraulic cylinder for customers from Ireland.
The material of the sliding part of the stern plate hydraulic cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.
stern plate hydraulic cylinder can not drive the load troubleshooting: oil pressure is too low. stern plate hydraulic cylinder selection specifications are too small. Leakage in stern plate hydraulic cylinder or associated hydraulic system element.
When the stern plate hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the stern plate hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the stern plate hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.
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.
What are the causes of hydraulic cylinder oil leakage?
First, between the piston rod and the guide sleeve: 1, the cylinder force is not good, there is a radial force between the piston rod and the guide sleeve there is a partial load, so that the oil seal is worn early, causing oil leakage. 2. The ambient temperature of the piston rod is high, especially radiant heat, and the oil seal aging is fast. 3. Whether the oil seal is selected correctly; Check whether the oil seal is damaged during installation. 4, guide sleeve and piston rod matching tolerance is correct. Second, between guide sleeve and cylinder: 1. Whether the O-ring on the guide sleeve is installed correctly, pay special attention to the O-ring can not "roll", especially some O-rings are die-pressed with a die-closing line. Third, common problems: 1, guide sleeve, cylinder, piston rod concentricity is poor. Fit tolerance is correct.
Does the sealing string of the upper and lower chamber of the hydraulic cylinder fall by itself?
It is possible, the probability accounts for 85% (depending on the weight), the weight is less than the system resistance, may not fall, the weight is greater than the system resistance, will not necessarily fall, so often check the equipment, safety first, find the problem in time to solve, the cylinder is not very expensive parts, maintenance does not cost much money, However, accidents caused by cylinder failure will lose several times the cost.
