Hydraulic transmission system, the hydraulic transmission system is generally an open loop system without feedback, which mainly transmits power, supplemented by information, and pursues the perfection of transmission characteristics. Hydraulic elements special-purpose orbit motor The characteristics of components and their interactions determine the working characteristics of the system, and its working quality is greatly affected by the changes of working conditions. Hydraulic drive system is widely used. The hydraulic system of most industrial equipment belongs to this category. In the hydraulic control system, servo valves and other electrohydraulic devices are mostly used in the hydraulic control system orbit motor Manufacturer The control valve constitutes a closed-loop system with feedback, which mainly transmits information, supplemented by power, and pursues the perfection of control performance. The system adds detection feedback, which can combine common components into an accurate control system, and its control quality is less affected by the change of working conditions. Hydraulic control system is widely used in high-precision CNC machine tools, metallurgy, aerospace and other industries.

The output pressure of the hydraulic motor also depends on the load. Rated pressure Pn: the rated pressure refers to the working pressure that the hydraulic motor can withstand during continuous operation. It can special-purpose orbit motor To ensure the volumetric efficiency and service life of the hydraulic motor. Working pressure P: the working pressure is the actual pressure of oil input when the hydraulic motor is working orbit motor Manufacturer power. Its value depends on the size of the load. However, the maximum working pressure is determined by the safety valve in the hydraulic system. The throttle adjustment value must not exceed the maximum pressure value of the hydraulic motor. The third is the maximum pressure: the limit pressure that the motor is allowed to overload in a short time. Pn ≤ Pmax value.

BM cycloidal hydraulic motor is a small low-speed high torque hydraulic motor with single axis flow distribution and fixed rotor set. Its advantages are as follows: 1. It is small in size and light in weight, and its overall size is much smaller than other types of hydraulic motors with the same torque. 2. Wide speed range, stepless speed regulation, minimum stable speed up to 15 rpm, convenient installation and layout, low investment cost. 3. It can be used in series or parallel in the hydraulic system. 4. The moment of inertia is small, and it is easy to start under load. It can rotate in both forward and reverse directions, and it does not need to stop when reversing. BM cycloidal motor is widely used in agriculture, fishery, light industry orbit motor Manufacturer The slewing mechanism of hoisting and transportation, mining, construction machinery and other machinery. Examples of BM cycloidal hydraulic motor used abroad; 1) Agricultural use: various combine harvesters, seeders, rotary tillers, lawn mowers, sprayers, feed mixers, ground drills. 2) Fishery use: net lifter. special-purpose orbit motor 3) Light industry: commercial winding machines, textile machines, printing machines, washing machines. 4) For construction industry: road roller, cement mixer, sweeper.

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 special-purpose orbit 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 Pingdingshan orbit 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.

During the operation of hydraulic transmission, the hydraulic actuator can be adjusted steplessly in a large range by adjusting the control valve, and the speed range can reach 2000 meters. Good operation ability and rapidity. The liquid is elastic and can absorb impact, so the hydraulic transmission movement is even and stable; It is easy to realize fast starting, braking and frequent reversing. Reciprocating rotation special-purpose orbit motor The reversing frequency of rotary motion can reach 500 times/minute, and the reciprocating linear motion can reach 1000 times/minute. It is easy to control operation and realize overload protection. The hydraulic system with convenient operation and control is convenient for automatic control, remote control and overload protection; Automatic lubrication during operation, which is beneficial to Pingdingshan Manufacturer Heat dissipation, prolong service life. It is convenient for automation and electromechanical hydraulic integration. Hydraulic technology is easy to combine with electronic control and electronic control technology to form an electromechanical hydraulic integration composite system to realize automatic cycle work.
