This article mainly introduces:

Greece hydraulic cylinder,extended hydraulic cylinder manufacturer,extended hydraulic cylinder

(Greece extended hydraulic cylinder,produced by Hebei Hengyu company）

extended hydraulic cylinder are widely used in Greece，because of simple structure and reliable operation，excellent temperature resistance，clever hydraulic energy conversion.So our company has designed extended hydraulic cylinder for customers from Greece.

Introduction to extended hydraulic cylinder:

Causes and countermeasures of oil extended hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the extended hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the extended hydraulic cylinder is visibly scarred, the extended hydraulic cylinder must be replaced. It can be pressurized at one end of the extended hydraulic cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most extended hydraulic cylinder piston drift may not come from the extended hydraulic cylinder, the above method to determine the extended hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

The extended hydraulic cylinder should be used correctly and maintained regularly. The extended hydraulic cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the extended hydraulic cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular extended hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

When the extended hydraulic cylinder is in use, ensure that the extended hydraulic cylinder and the surrounding environment should be clean. The tank should be sealed to prevent contamination. Pipelines and fuel tanks should be cleaned to prevent falling off the oxide sheet and other debris. Clean with lint-free cloth or special paper. Twine and binder should not be used as sealing materials. Hydraulic oil according to the design requirements, pay attention to the change of oil temperature and oil pressure. When there is no load, unscrew the exhaust bolt for exhaust.

Answers to some questions about extended hydraulic cylinder:

How big is a 300-ton cylinder piston?
The rated pressure of the oil pump is 31.5 mpa, the nominal pressure of the hydraulic press is 3150 kN, then the calculated cross-sectional area of the cylinder: S=3150000/31500000=0.1 square meters diameter is: 2* root sign (0.1/3.14) =2*0.178 m =0.356 m 3150 kN hydraulic press is commonly equipped with 31.5 mpa 63 l/min axial piston pump. There are many variable forms of axial piston pump, and the motor size of the pump with the same flow and pressure is not uniform. 31.5 mpa 63 L/min automatic variable pump, can be equipped with 15 kW 4 stage motor; The manual variable pump needs to be equipped with 22 kW 4-stage motor.

How big is the motor and oil pump for the 80 cylinder?
Pump motor selection is not only related to cylinder diameter but also speed system, it is recommended to provide system diagram and speed requirements, generally speaking, most of the 80 cylinder on the market is equipped with 3-4KW motor, 10-20 oil pump.
