This article mainly introduces:
Uganda hydraulic cylinder,servo cylinder manufacturer,servo cylinder
(Uganda servo cylinder,produced by Hengyu Hydraulic Co., Ltd）
servo cylinder are widely used in Uganda，because of no need for deceleration device，long service life，smooth movement.So our company has designed servo cylinder for customers from Uganda.
If the seal of the servo 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 servo cylinder, and the phenomenon of "pulling the servo 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.
When using the servo cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the servo cylinder block. If the servo cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the servo cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the servo cylinder, so that the working efficiency of the servo cylinder is reduced.
The material of the sliding part of the servo 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.
If the piston rod and servo cylinder are stuck or the servo cylinder is blocked, at this time, no matter how to operate, the servo cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the servo cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.
Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
The two cylinders of the bending machine are out of sync?
Check whether the sliding slide is worn, adjust its tightness, so that both sides are consistent, check whether the two cylinder tubing is connected, tighten the flow valve, pressure, let the cylinder air discharge.
