(Finland retractable cylinder,produced by Hengyu Group）

retractable cylinder are widely used in Finland，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed retractable cylinder for customers from Finland.

Introduction to retractable cylinder:

The internal leakage of the retractable cylinder should be prevented when the retractable cylinder is used. The internal leakage of retractable cylinder includes the leakage caused by excessive wear of retractable cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

The difference between the integral retractable cylinder and the split retractable cylinder: The integral retractable cylinder and the split retractable cylinder in the retractable cylinder are two different retractable cylinders, and they are very different. The whole retractable cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split retractable cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and retractable cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

The retractable cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the retractable cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the retractable cylinder wall due to the stiffness and the weight of the parts, causing scars.

When the retractable cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the retractable cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil retractable cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical retractable cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the retractable cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

Answers to some questions about retractable cylinder:

What are the standard cylinder models for hydraulic cylinders?
National standard GB/T2348-1993 specifies the hydraulic cylinder inner diameter series, you can check GB/T2348-1993 relevant regulations.

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.
