(Oman hydraulic lifting cylinder,produced by Hebei Hengyu company）

hydraulic lifting cylinder are widely used in Oman，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed hydraulic lifting cylinder for customers from Oman.

Introduction to hydraulic lifting cylinder:

Regular maintenance of the hydraulic lifting cylinder includes: regular tightening, hydraulic lifting cylinder fastening screws and gland screws, hydraulic lifting cylinder piston rod stop adjustment screws, should be tightened once a month, tighten each screw evenly, and achieve the corresponding tightening torque. Replace the seal regularly, it is recommended to replace the seal of the hydraulic lifting cylinder once a year. Clean regularly, the hydraulic lifting cylinder is cleaned every other year, and the seals are replaced while cleaning.

When the hydraulic oil is not pumped into the hydraulic lifting cylinder, it is necessary to check whether the tubing, oil circuit, especially the hose joint has been blocked, and the relevant oil circuit from the hydraulic lifting cylinder to the pump should be checked in turn and blocked; Check whether the seal between the taper valve and the seat of the relief valve is good; Check whether the solenoid valve spring is damaged or whether the solenoid coil is burned out; Whether the oil circuit is switched is insensitive.

The hydraulic lifting cylinder should be vented: when the hydraulic lifting cylinder is installed or parked for a long time to work again, the air will penetrate into the hydraulic lifting cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the hydraulic lifting cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the hydraulic lifting cylinder, the oil is best entered and discharged from the highest point of the hydraulic lifting cylinder. hydraulic lifting 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.

When the hydraulic lifting 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 hydraulic lifting cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the hydraulic lifting 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 hydraulic lifting cylinder:

How to deal with the surface degreasing process before spraying paint after cylinder assembly, and what degreasing agent is used?
Cylinder painting, generally using the following process (note: the cylinder is best painted, do not spray powder coating, because the powder coating curing temperature is high, will lead to sealing defects and oil leakage) : Pre-degreasing - degreasing - washing - washing - pickling - washing - washing - table adjustment - phosphating - washing - washing - drying - polishing - spray primer - spray paint degreasing agent generally use neutral or weak alkaline degreasing agent, phosphating liquid generally use zinc phosphating liquid.

What are the connection methods of the hydraulic cylinder? The connection modes of the cylinder and the actuator are earring connection, hinge shaft connection, thread connection, etc. The connection modes of tubing and cylinder are threaded connection, flange connection, etc.
