When the main reversing valve of the central closing system and the central closing system is in the neutral position, all oil ports of the reversing valve are closed. If a fixed pump is used for oil supply, the liquid of the hydraulic pump will return to the tank at high pressure through the overflow valve. When the reversing valve is in neutral position, energy transmission starts from the high value, that is, the maximum pressure regulating value of the system. Just reverse High torque cycloidal hydraulic motor Price , its energy can be used by the actuator. When the reversing valve is in the middle position, it sometimes bears all the pressure of the system, so the internal leakage is greater than that of the open system. Generally, when the Guangzhou High torque cycloidal hydraulic motor In this case, the energy consumption of the closed loop is high, but if the intermediate unloading measures are added or the pressure compensated variable pump is used for oil supply, the energy consumption of the closed loop can be greatly reduced. Closed hydraulic systems are used for a variety of equipment.

Of course, you can increase the traffic want to buy High torque cycloidal hydraulic motor Increase the speed, but how much will affect the service life. As long as it is within the rated power range, there is no problem. If the oil pressure reaches the rated pressure and the speed increases, it will exceed the power range it can withstand. Of course, it will damage the service life of the cycloidal hydraulic motor. Just like not eating so much hard food, it will damage the stomach. Increasing the flow can only increase the speed in a limited way, from 500 to 900, change the model of the motor, increase the flow of the cycloidal motor, increase the speed without control, increase the internal oil pressure, increase the internal leakage, directly reduce the efficiency, and damage the motor. Above Guangzhou Price Ming can try, and consult the cycloid hydraulic motor expert if he thinks the error is found.

When the high-pressure oil enters the oil distribution shaft and enters each plunger cylinder hole of the working section through the oil distribution window, the corresponding plunger set is pushed against the curved surface of the cam ring L (housing), Guangzhou High torque cycloidal hydraulic motor The cam ring surface gives a reaction force to the plunger at the contact position. This reaction force N acts on the common plane where the cam ring surface contacts the roller. This normal reaction force N can be decomposed into radial force PH and circumferential force T, which are balanced with the hydraulic pressure at the bottom of the plunger, while the circumferential force T overcomes the load torque, want to buy High torque cycloidal hydraulic motor Drive cylinder 2 to rotate. Under this working condition, the cam ring and oil distribution shaft do not rotate. At this time, the plunger corresponding to the oil return section of the cam gear moves in the opposite direction, and the oil is discharged through the oil distribution shaft.

After disassembling and inspecting the hydraulic motor installed on the drill, it was found that the friction surface of the valve disc and the port plate of the hydraulic motor was severely worn, and the deepest worn part was 0. 15mm; The output shaft oil seal is leaking. Cause analysis of oil leakage of output shaft oil seal. After disassembly inspection and test, the axial and radial clearances of the output shaft meet the standard requirements want to buy High torque cycloidal hydraulic motor There is no obvious wear on the oil seal mating surface. However, it is found that the oil seal rubber has hardened and its elasticity has deteriorated. With the increase of sealing lip wear, the pre tightening capacity and sealing performance decrease, and the excessive oil temperature accelerates the wear of sealing lip; In addition, due to the liquid Guangzhou High torque cycloidal hydraulic motor The leakage of the pressure motor causes the back pressure in the housing to be too high, which further aggravates the wear and leakage of the sealing lip. The smaller the friction of the rotor in the stator sleeve, the higher the mechanical efficiency of the motor.
