Pakistan hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder(Pakistan unidirectional cylinder,produced by Hengyu Hydraulic Co., Ltd)
unidirectional cylinder are widely used in Pakistan,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed unidirectional cylinder for customers from Pakistan.
How to repair the unidirectional cylinder body when it is damaged: When the unidirectional cylinder has trace deformation and shallow tensile marks, the unidirectional cylinder is repaired by strong honing process. The heavy honing process can repair unidirectional 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 unidirectional cylinder can meet the technical requirements.
If the seal of the unidirectional cylinder is abnormal wear, you can check whether the speed control valve is improperly adjusted, resulting in too high back pressure and improper installation of the seal or hydraulic oil contamination. The second is whether there is a foreign body entering the assembly and the quality of the sealing material is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and unidirectional cylinder, and the phenomenon of "pulling the unidirectional cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operation and improvement should be done according to the installation instructions.
In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular unidirectional cylinder action. Troubleshooting method: Replace the rubber hose.
Do not enter foreign bodies when installing the unidirectional cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.
What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
What's a minus 40 cylinder made of?
Construction with 1Cr18Ni9Ti, in low temperature conditions impact and tensile strength are very good, can withstand -100 degrees of low temperature, corrosion resistance, material price is not very high, more economic.
