Ethiopia hydraulic cylinder,servo cylinder manufacturer,servo cylinder(Ethiopia servo cylinder,produced by Hengyu Hydraulic Co., Ltd)
servo cylinder are widely used in Ethiopia,because of no need for deceleration device,long service life,smooth movement.So our company has designed servo cylinder for customers from Ethiopia.
Causes and countermeasures of oil servo cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the servo cylinder will lead to premature wear of the piston seal, replace the piston seal; If the servo cylinder is visibly scarred, the servo cylinder must be replaced. It can be pressurized at one end of the servo cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most servo cylinder piston drift may not come from the servo cylinder, the above method to determine the servo cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
When the servo cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the servo cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.
The body of the servo cylinder on the processing process requirements: the body of the servo cylinder is an important and essential part of the servo cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the servo cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.
Disassembly servo cylinder: When disassembly servo cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the servo cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the servo cylinder.
What are the reasons why the hydraulic cylinder action is slower than normal?
There are many factors that cause this problem. First, measure the pressure of the main system to see whether the pressure of the main system under the pressure state is consistent with the initial setting. Before measuring the pressure, it is best to check the hydraulic oil and suction oil filter and replace or clean it. Second, check the main relief valve of the reversing control multiway valve to see if there is damage or foreign matter blocking, and clean it. If your pump is a gear pump, the problem should generally be small. Second, look at traffic. There is no leakage in the cylinder, leakage in the reversing valve spool and so on.
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.
