As the power source and actuator of the hydraulic system, the performance of the hydraulic motor has a great impact on the performance of the entire hydraulic system. Therefore, the importance of studying the hydraulic motor performance test system is want to buy Low speed cycloidal hydraulic motor It is very important that the rise and application of hydraulic testing technology based on virtual instrument has opened up a broad prospect for the performance testing of hydraulic motors. Hydraulic motors are widely used in machine tools, metallurgy, engineering machinery, plastic machinery, agricultural machinery, mining machinery, marine machinery and many other important fields. The performance of the hydraulic motor has a decisive impact on the whole system, and will directly affect the stability of the system. At the same time, the performance of the hydraulic motor will have an impact on the life of the system components and the production efficiency of the system. Anshan manufactor Unexpected failure of hydraulic motor will greatly reduce production efficiency.

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 Low speed cycloidal hydraulic motor manufactor 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 Anshan Low speed cycloidal hydraulic 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.

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 Low speed cycloidal hydraulic motor manufactor → 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 Low speed cycloidal hydraulic motor The rotor is driven by 42 pressure oil with the maximum volume for 6 revolutions, so the motor has a large emissions.

At present, the system used in series by multiple cycloidal motors (see Figure 1) is applied to sweepers, trenchless drills and airport luggage carts. The output shaft of the hydraulic motor often leaks oil during use, so it is useless to replace the dynamic seal of the output shaft. In series application, the problem of casing oil leakage pressure is ignored. The oil leakage pressure of the housing refers to the maximum pressure that the motor shaft seal can bear after the hydraulic motor is fully lubricated inside; If the hydraulic motor is applied want to buy Low speed cycloidal hydraulic motor Improper. After the machine has been working continuously for a period of time, due to various factors, the oil in the housing will not be released, resulting in higher and higher pressure in the housing of the hydraulic motor, which first leads to the failure of the shaft seal. The casing leakage pressure mentioned here is not the bursting pressure of the casing, but the pressure that the motor output shaft dynamic seal can bear. In the motor samples of some manufacturers, only the back pressure is mentioned. Actually, back pressure refers to electricity Low speed cycloidal hydraulic motor manufactor The return oil pressure of the engine, not the oil discharge pressure of the casing. During operation, the requirements for the oil discharge pressure of the cycloidal motor housing are as follows. Eaton is the world's first cycloid motor manufacturer. In China's domestic cycloidal motor manufacturing industry, Jining Jinjia Hydraulic Co., Ltd. uses Eaton technology to produce cycloidal motors. Its output shaft dynamic seal has better bearing capacity, that is, the unique internal oil circuit design of the company's products enables internal oil drainage not only to lubricate parts, but also to discharge excess oil while maintaining a certain housing oil drainage pressure.

1. The hydraulic system is characterized by high energy density. For motors with the same power, hydraulic motors are much smaller and lighter than motors. And it is easy to apply to mobile devices. 2. The hydraulic motor has convenient speed regulation, which can be adjusted infinitely from 0 to the maximum speed according to the adjustment of the hydraulic valve. The motor itself does not need special design and has low cost. This is much cheaper than motor+reducer, or variable frequency motor and servo motor. 3. The hydraulic motor is totally enclosed and can be safely used in dusty, wet (even underwater) and flammable environments, which is much more reliable than explosion-proof (flameproof) motors. 4. The hydraulic system has strong anti overload capacity, and it is protected by the overflow valve, allowing long (relatively) frequent overloads. It is easy to recover under overload conditions, without damaging the equipment or restarting the equipment. These unparalleled advantages of motors have made hydraulic motors and hydraulic technology rapidly spread and popularized all over the world in the past 20 years. People increasingly feel the importance of hydraulic motors in practice.
