(Jordan servo hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

servo hydraulic cylinder are widely used in Jordan，because of smooth movement，high work efficiency，excellent fatigue and impact resistance.So our company has designed servo hydraulic cylinder for customers from Jordan.

Introduction to servo hydraulic cylinder:

The "O" ring can be used as an auxiliary seal inside the servo hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the servo hydraulic cylinder, and can be completely sealed.

When the servo hydraulic cylinder needs to be stored for a period of time, please follow the recommended methods: The servo hydraulic cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the servo hydraulic cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil servo hydraulic cylinder should not be in direct contact with water vapor for a long time. The servo hydraulic cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the servo hydraulic cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the servo hydraulic cylinder Before working, the servo hydraulic cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the servo hydraulic cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

When the servo hydraulic cylinder is customized, if there are high requirements for the quality of the servo hydraulic cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the servo hydraulic cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the servo hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

servo hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

Answers to some questions about servo hydraulic cylinder:

How big is the pump and motor for 20 tons of hydraulic cylinder?
According to the working pressure of 25 mpa estimate, the cylinder should use 100mm bore, 63mm piston rod, stroke 40mm. According to 30 reciprocating calculation, the flow rate is about 25 liters/minute. The motor power is 11 kW, want to be cheap, use 25SCY14-1B oil pump can be.

Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.
