(Egypt stern plate hydraulic cylinder,produced by Hengyu Group）

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

Introduction to stern plate hydraulic cylinder:

The material, shape and compression of the stern plate hydraulic cylinder seal have a great impact on the service life and work efficiency of the stern plate hydraulic cylinder. In addition to requiring a reliable seal, it should also have a long service life and less friction loss. At present, there are many seal manufacturers in the country, and it is also crucial to choose high-quality seals with reliable and stable quality.

stern plate hydraulic cylinder use should try to avoid sealing belt into the stern plate hydraulic cylinder. As a simple sealing material, polytetrafluoroethylene plastic sealing tape is often used in installation and inspection, and if the winding method of the linear and ribbon-shaped sealing material is wrong, the sealing tape will be cut off and enter the stern plate hydraulic cylinder. The wire belt seal will not have any effect on the winding of the sliding part, but it will cause the check valve of the stern plate hydraulic cylinder to fail to operate or the buffer regulating valve can not be adjusted to the end. For the circuit, it may cause the action of the reversing valve, the relief valve and the reducing valve to fail.

The wear of the hard chromium plating layer of the stern plate hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.

When installing the stern plate hydraulic cylinder, the axial ends of the stern plate hydraulic cylinder cannot be fixed. Due to the effect of liquid pressure and thermal expansion in the stern plate hydraulic cylinder, there is axial expansion. If the two ends of the stern plate hydraulic cylinder are fixed, all parts of the stern plate hydraulic cylinder will be deformed. When disassembling the stern plate hydraulic cylinder, it is strictly forbidden to hammer the stern plate hydraulic cylinder and the piston surface, such as the stern plate hydraulic cylinder hole and the piston surface is damaged, do not allow sandpaper grinding, to use a fine oil stone carefully grinding. The clearance between the guide sleeve and the piston rod should meet the requirements.

Answers to some questions about stern plate hydraulic cylinder:

What factors does the movement speed of the cylinder in the hydraulic system depend on?
The hydraulic system should be the piston movement in the cylinder, and the speed should also be the speed of the piston, according to the piston speed formula: v=4qm/pai*(D^2-d^2) where q is the flow rate of the input hydraulic cylinder, m is the volumetric efficiency of the hydraulic cylinder, D, d is the diameter of the piston and piston rod, because other factors are determined, the movement speed of the cylinder depends on the flow rate.

How to select the 2.5T bearing cylinder and hydraulic pump?
2,5 ton load is not heavy, you can use the rated pressure of 16 mpa gear pump, neither waste nor save cost, load/pressure = cylinder diameter, preset pressure of 8 mpa, 2500 (kg) /80 (bar) =31.25 square centimeters, in the open =63 mm, cylinder diameter can be selected 63 mm, stroke according to the situation, Hydraulic pump select gear pump, if there is a speed requirement, in order to calculate the displacement, the motor power also needs to determine the displacement of the pump to calculate.
