Uganda hydraulic cylinder,reset cylinder manufacturer,reset cylinder
(Uganda reset cylinder,produced by Hengyu Hydraulic Co., Ltd）
reset cylinder are widely used in Uganda，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed reset cylinder for customers from Uganda.
Before the reset cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
reset cylinder installation precautions: Before installing the reset cylinder into the system, the parameters on the reset cylinder label should be compared with the parameters when ordering. The base of the reset cylinder must have sufficient stiffness, otherwise the reset cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.
Improve the service life of the reset 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 reset cylinder (such as the reset 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 reset 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 reset cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single reset cylinder exhaust.
reset cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the reset cylinder is placed for a period of time, the reset cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.
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.
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.
