S.Africa large stroke cylinder

(S.Africa large stroke cylinder,produced by Hebei Hengyu company)

large stroke cylinder are widely used in S.Africa,because of excellent temperature resistance,no transmission clearance,powerful torque.So our company has designed large stroke cylinder for customers from S.Africa.

Introduction to large stroke cylinder:

The large stroke cylinder should be vented: when the large stroke cylinder is installed or parked for a long time to work again, the air will penetrate into the large stroke cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the large stroke cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the large stroke cylinder, the oil is best entered and discharged from the highest point of the large stroke cylinder. large stroke cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

large stroke cylinder body inspection: The inner surface of the large stroke cylinder and the piston seal are the main factors causing the leakage in the large stroke cylinder, if the large stroke cylinder has a longitudinal tensile mark, even if the new piston seal is replaced, it can not effectively eliminate the fault, the inner surface of the large stroke cylinder mainly checks whether the dimensional tolerance and shape and position tolerance meet the technical requirements, there is no longitudinal tensile mark, and measures the depth of the longitudinal tensile mark, in order to take the corresponding solution.

Disassembly large stroke cylinder: When disassembly large stroke cylinder, strictly prevent damage to the screw thread at the top of the piston rod, the screw thread of the large stroke cylinder head and the surface of the piston rod. It should also be noted that the piston cannot be played out from the large stroke cylinder.

When the large stroke cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the large stroke cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the large stroke cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about large stroke cylinder:

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.

Is the hydraulic cylinder leaking because there is no pressure?
HC hydraulic cylinder common leakage reasons, first: most of the reasons are because the seal surface wear or aging leads to poor sealing, so there is no pressure to operate, as long as the piston seal can be replaced. Second: It may also be the piston rod strain, repair the piston rod is good. If it is because the piston strength is not enough and the playing time is long, it is necessary to replace the piston.
