When the working load changes from low speed to high speed in a wide range, the hydraulic motor is also required to be able to drive and regulate speed in the corresponding wide range, which requires the motor to have good low-speed stability and high speed performance. The speed regulation range K of the hydraulic motor is usually expressed by the ratio of the allowable maximum speed to the minimum speed. want to buy orbit motor It is the highest operating speed of hydraulic motor, but it is limited by many factors, mainly including: 1. Service life. After the speed increases, each pair is worn Qinzhou Price The service life is shortened. 2、 Mechanical efficiency limits. At high speed, the hydraulic motor needs to input large flow, accordingly, the hydraulic loss of each circulating component increases, reducing the mechanical efficiency.

(1) Oil leakage at the shaft end: because the oil seal and output shaft are under constant friction during the use of the hydraulic motor, the wear of the contact surface between the oil seal and the shaft will be caused Qinzhou orbit motor A certain limit will make the oil seal lose its sealing effect, and oil will leak. Our solution is very simple: replace the oil seal. If the output shaft is seriously worn, it must be replaced. (2) Crevice oil leakage: the "O" ring between the motor housing and the front side plate, or between the front side plate and the stator body, is aged orbit motor Price Just replace the "O" ring. (3) Oil leakage at the cover: the "O" ring under the cover is aged and loses its sealing effect. The probability of this situation is very low, even if it happens, just replace the "O" ring.

The manufacturer of the hydraulic motor has explained to us the relevant knowledge about the speed and low-speed stability of the hydraulic motor. The speed of the hydraulic motor depends on the flow of the supply fluid q and the discharge of the hydraulic motor itself v. The hydraulic motor has internal leakage. Not all the liquid entering the motor drives the hydraulic motor to work. Some of the liquid is lost due to leakage, and the actual speed of the motor is lower than the ideal situation. When the working speed of the hydraulic motor is too low, it cannot maintain a uniform speed, and it stops when entering Qinzhou orbit motor The unstable state is a creeping phenomenon. The high-speed hydraulic motor is required to work at a speed below 10r/min and the low-speed high torque hydraulic motor is required to work at a speed below 3r/min. All hydraulic motors can meet the requirements. Generally speaking, the low-speed stability of low-speed large torque hydraulic motors is better than that of high-speed motors. Due to the large emissions and size of the low-speed high torque motor, the sliding speed of the friction pair will not be too low even if the rotation speed is low want to buy orbit motor Large emissions, relatively small impact of leakage, large rotation inertia of the motor itself, easy to obtain good low-speed stability.

Oil filling process sequence: shell oil filler → oil filling sleeve groove → oil filling sleeve groove → shell oil filling hole → diaphragm → stator. Oil drainage process sequence: rotating stator → diaphragm orbit motor Price → Shell oil distribution hole → oil distribution jacket longitudinal groove → oil distribution jacket groove → shell oil return port. The rotating motion of the rotor includes rotation (rotation in the direction of expanding the high-pressure cavity around the center of the rotor) and revolution (rotation in the direction of deviation from the radius around the center of the stator). The rotation of the rotor is opposite to the revolution direction, and the rotation is transmitted to the output shaft through the linkage shaft. Rotor rotates for 1 cycle want to buy orbit motor The rotor is driven by 42 pressure oil with the maximum volume for 6 revolutions, so the motor has a large emissions.

The weight per unit of electricity is very light. Statistics show that the weight of hydraulic pump and hydraulic motor per unit power is only the generator. 1/10 of the motor, hydraulic pump and hydraulic motor can be as small as 0.0025N/W, and the generator and motor with the same power can be about 0.03N/W. As for size, the former is about 12%~13% of the latter. In terms of output force, it is easy to get extremely high pressure hydraulic fluid with a pump, which will produce great force after being delivered to the hydraulic cylinder. Therefore, hydraulic technology has the advantages of light weight Qinzhou Price The outstanding characteristics of small size and large output are conducive to the miniaturization and miniaturization of mechanical equipment and its control system for high-power operation. Flexible and convenient layout. The configuration of hydraulic components is not restricted by the strict space position, and it is easy to pass according to the needs of the machine. The connection of all parts of the system is realized through pipes, and the layout setting has great flexibility want to buy orbit motor Soft, which can form a complex system that is difficult to form by other methods.

1) Select the hydraulic pump or motor with good quality and conduct regular maintenance. For example, if the tooth profile accuracy of the gear is low, grind the gear to meet the requirements of the contact surface; 2) If the vane pump has trapped oil, the triangular groove of the oil distributor should be corrected to remove the trapped oil; 3) If the axial clearance of the hydraulic pump is too large and the oil delivery is insufficient orbit motor Price Repair to keep the axial clearance within the allowable range; 4) If the hydraulic pump is not selected correctly, it should be replaced immediately. 3. The reversing valve is improperly adjusted. Improper adjustment of the reversing valve causes the valve core of the reversing valve to move too fast, resulting in reversing shock, noise and vibration. During operation, the valve core branch of hydraulic valve Qinzhou orbit motor Support on the spring. When its frequency is close to the pulsating frequency of oil delivery rate of hydraulic pump or other vibration sources, vibration and noise will be generated.
