(Egypt jacking hydraulic cylinder,produced by Hebei Hengyu company）

jacking hydraulic cylinder are widely used in Egypt，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed jacking hydraulic cylinder for customers from Egypt.

Introduction to jacking hydraulic cylinder:

jacking hydraulic cylinder buffer valve inspection and maintenance: For the valve buffer jacking hydraulic cylinder, the focus should be on checking the wear of the buffer valve spool and seat. Once it is found that the amount of wear increases and the seal fails, it should be replaced. It can also be repaired by using abrasive spool and seat matching grinding method.

When the jacking hydraulic cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

The commonly used buffer structure of the jacking hydraulic cylinder is composed of a piston boss and a jacking hydraulic cylinder head groove. When the piston moves close to the jacking hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Regular maintenance of the jacking hydraulic cylinder includes: regular tightening, jacking hydraulic cylinder fastening screws and gland screws, jacking hydraulic 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 jacking hydraulic cylinder once a year. Clean regularly, the jacking hydraulic cylinder is cleaned every other year, and the seals are replaced while cleaning.

Answers to some questions about jacking hydraulic cylinder:

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.

How to calculate the hydraulic cylinder pressure? How much pressure can put up how much weight?
If you want to calculate the pressure of the cylinder, you must know the inner diameter of the cylinder, if the piston rod is needed to lift the weight, it should be: cylinder (no piston rod end) pressure = load (4000N) ÷{(PI /4)X the square of the cylinder diameter (mm) ", it has nothing to do with the piston rod diameter, the rod diameter of the piston rod is only related to the stability of the cylinder. The pressure inside the cylinder should be p=F/S=400×10/(3.14×(0.5×25)×(0.5×25))=8.15MPa which means that you need to provide at least that much pressure to complete the operation.
