S.Africa hydraulic cylinder,pushing cylinder manufacturer,pushing cylinder

(S.Africa pushing cylinder,produced by Hengyu Hydraulic Cylinder Factory）

pushing cylinder are widely used in S.Africa，because of long service life，high work efficiency，excellent temperature resistance.So our company has designed pushing cylinder for customers from S.Africa.

Introduction to pushing cylinder:

Before the pushing cylinder is removed, the system should be unloaded, the loop pressure is zero, the oil source should be cut off, and the oil port should be blocked after the oil port distribution pipe is loosened.

Protection of the pushing cylinder surface: During the dismantling process, safety protection should be carried out on the pushing cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the pushing cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the pushing cylinder should be cleaned up in time.

When the pushing cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the pushing cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

The assembly work of the pushing cylinder has a great impact on the quality of the pushing cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

Answers to some questions about pushing cylinder:

The difference between the overall cylinder and the separate cylinder of the truck?
The whole cylinder is cast in one piece, and such a cylinder generally does not leak oil. Split cylinder refers to two welded, easy to leak oil in the welding place, resulting in damage to the cylinder, or its body can not get up, many people do not use this kind of cylinder now.

Why the lifting cylinder falling by itself?
May be there is a pressure relief point. Check and repair the following parts: whether there is oil leakage in the transparent pipe at the top of the cylinder: the cylinder oil seal is broken, and the cylinder and oil seal need to be replaced; No: The multiway valve has pressure relief and needs to be repaired. Maintenance in accordance with routine maintenance items can reduce mechanical failures: 1. Check whether the thermostat works normally. 2, check the transmission shift work is normal. 3. Check the tightness of the fan belt. 4, check whether the diesel tank oil inlet filter is blocked or damaged, and clean or replace the filter. 5. Check and adjust the valve clearance.
