(Czech Republic spring return cylinder,produced by Hengyu Group）

spring return cylinder are widely used in Czech Republic，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed spring return cylinder for customers from Czech Republic.

Introduction to spring return cylinder:

When the spring return cylinder needs to be disassembled for maintenance due to leakage and other faults, the piston should be moved to the bottom position of the spring return cylinder, and hard beating and sudden drop are strictly prohibited during disassembly.

When the spring return cylinder is installed, the piston and the spring return cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the spring return cylinder head boss is easy to cause scars when it hits the inner surface of the spring return cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized spring return cylinders, only careful and careful operation can be avoided.

When the initial action of the spring return cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the spring return cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

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

Answers to some questions about spring return cylinder:

For a cylinder with a piston diameter of 100mm and a system pressure of 10MPa, what is the thrust?
Thrust is 7850 kg. Piston area A= πR^2=7850 square mm =78.5 square cm 10MPa = 100kg/cm^2 "^2" is square F = A x P =78.5 x 100=7850 kg.

What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.
