Estonia 300 tons hydrauli ccylinder

(Estonia 300 tons hydrauli ccylinder,produced by Hengyu Hydraulic Cylinder Factory)

300 tons hydrauli ccylinder are widely used in Estonia,because of smooth movement,high work efficiency,excellent fatigue and impact resistance.So our company has designed 300 tons hydrauli ccylinder for customers from Estonia.

Introduction to 300 tons hydrauli ccylinder:

The difference between the plunger 300 tons hydrauli ccylinder and the piston 300 tons hydrauli ccylinder is that the piston in the 300 tons hydrauli ccylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type 300 tons hydrauli ccylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

When the 300 tons hydrauli ccylinder is installed on the main engine, the oil port piping part and the guide sleeve should be checked for oil leakage in the running test, and the earring and the middle hinge shaft bearing should be refueled.

If the 300 tons hydrauli ccylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the 300 tons hydrauli ccylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow 300 tons hydrauli ccylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the 300 tons hydrauli ccylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the 300 tons hydrauli ccylinder includes the leakage caused by excessive wear of the 300 tons hydrauli ccylinder block seal, the piston rod and the seal cover seal and the 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 main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and 300 tons hydrauli ccylinder, and the phenomenon of "pulling the 300 tons hydrauli ccylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

In order to ensure the service life of the 300 tons hydrauli ccylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the 300 tons hydrauli ccylinder, causing damage to the seal and causing leakage in the 300 tons hydrauli ccylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

Answers to some questions about 300 tons hydrauli ccylinder:

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.

In a hydraulic system, a hydraulic pump has many hydraulic cylinders and hydraulic motors, and these executive components do not coordinate their actions with each other.
A load-sensitive variable pump can be used if these components sometimes need to work simultaneously and the power required is large. The required flow is distributed by the multi-way reversing valve, and the required flow and pressure changes are automatically adjusted by the hydraulic pump. Pressure reducing valves can be used for particularly low pressure circuits. Because you execute more components, the use of quantitative pump will cause a waste of energy, the system heat is large, not suitable.
