(Morocco jack cylinder,produced by Hengyu Hydraulic Cylinder Factory）

jack cylinder are widely used in Morocco，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed jack cylinder for customers from Morocco.

Introduction to jack cylinder:

The jack cylinder should be avoided for a long time without use, if it is indeed idle for a long time for some reason, it should also be regularly turned on for empty operation, so that its parts can be fully lubricated, so as to avoid rust on the working surface and affect the normal work in the future. (If it cannot be turned on and run, a small amount of lubricating oil can be applied on its outer surface for protection) ' The use of the jack cylinder should pay attention to: the operation should be as far away from the jack cylinder as possible, to avoid falling objects, knocking, rubbing the jack cylinder coating. When cleaning the jack cylinder, only use soft materials (such as cotton) to wipe, and do not scratch high-hardness materials. Do not use the jack cylinder when the oil temperature exceeds 70 ° C.

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

When using the jack cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the jack cylinder block. If the jack cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the jack cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the jack cylinder, so that the working efficiency of the jack cylinder is reduced.

The piston seal of the jack cylinder is the main element to prevent leakage in the jack cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about jack 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.

How to deal with oil cylinder leakage?
The causes of oil leakage and treatment methods are as follows: (1) The spool is stuck or the valve hole is blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the hydraulic cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check valve body for wear. (2) The piston rod and cylinder are stuck or the hydraulic cylinder is blocked. At this time, no matter how to operate, the hydraulic cylinder does not move or moves very little. At this time, it should be checked whether the piston and piston rod seal is too tight, whether it enters the dirt and colloid precipitate: whether the shaft line of the piston rod and the cylinder is in alignment, and whether the wearing parts and seals are invalid.
