Libya hydraulic cylinder,lift cylinder of forklift truck manufacturer,lift cylinder of forklift truck(Libya lift cylinder of forklift truck,produced by Hengyu Hydraulic Co., Ltd)
lift cylinder of forklift truck are widely used in Libya,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed lift cylinder of forklift truck for customers from Libya.
The lift cylinder of forklift truck pipe should not be left behind when deburring at both ends after the fixed length processing. In addition, the placement of steel pipes near the site of welding pipeline operations is the cause of welding foreign objects. The pipes placed near the welding operation site should be sealed. It must also be noted that pipe fitting materials should be fully prepared on a dust-free workbench.
In use, the lift cylinder of forklift truck should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the lift cylinder of forklift truck.
Causes and countermeasures of oil lift cylinder of forklift truck leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the lift cylinder of forklift truck will lead to premature wear of the piston seal, replace the piston seal; If the lift cylinder of forklift truck is visibly scarred, the lift cylinder of forklift truck must be replaced. It can be pressurized at one end of the lift cylinder of forklift truck 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 lift cylinder of forklift truck piston drift may not come from the lift cylinder of forklift truck, the above method to determine the lift cylinder of forklift truck without internal leakage is helpful to determine the problem of the hydraulic system related components.
The lift cylinder of forklift truck is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the lift cylinder of forklift truck is proportional to the effective area of the piston and the pressure difference between the two sides; The lift cylinder of forklift truck is basically composed of lift cylinder of forklift truck and lift cylinder of forklift truck head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
What is the function of the hinged cylinder of the shield machine?
The articulated cylinder is used for the shield when the radius of curvature is very small during the propulsion process, that is, for turning. For example, a propulsion section with a radius of curvature of R150 can only be turned using an articulated system due to the sensitivity of the shield body (i.e. the length of the shield body divided by its outside diameter). However, in the construction process, the use of articulated systems is not much.
Is there a national standard for the testing of hydraulic cylinders?
Generally speaking, the cylinder test is carried out according to JB/JQ20302 Allowable leakage of cylinder in pre-factory leakage test. GB2879 hydraulic cylinder piston and piston rod dynamic seal groove type, size and tolerance. GB6578 hydraulic cylinder piston rod dust ring groove type, size and tolerance. GB7938 hydraulic cylinder and cylinder nominal pressure series, etc.
