Of course, you can increase the traffic customized Cycloidal hydraulic motor with brake 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 Guangdong manufactor Ming can try, and consult the cycloid hydraulic motor expert if he thinks the error is found.

Functions: It is used for the storage, supply and recovery of hydraulic media, the connection between hydraulic components and the transmission of energy carrying hydraulic media, filtering impurities in the hydraulic media, keeping the media required for the normal operation of the system clean, heating or cooling the system, storing and releasing hydraulic energy or absorbing hydraulic pulsation and impact, and displaying the pressure and oil temperature of the system; Hydraulic working medium: various hydraulic oils (fluids), efficacy: as the energy carrying medium of the system, it plays the role of lubrication and cooling while transferring energy. Generally speaking, the hydraulic components that can complete certain specific functions are called hydraulic circuits. In order to meet the working requirements of certain machinery or equipment, the overall structure of several special basic functional circuits connected or combined together is called hydraulic system.

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 customized Cycloidal hydraulic motor with brake 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 Guangdong Cycloidal hydraulic motor with brake 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.

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 customized Cycloidal hydraulic motor with brake 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 Cycloidal hydraulic motor with brake 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.

Along the revolution direction of the rotor, the volume of the tooth cavity at the front side of the connection between the rotor and the stator becomes smaller, which is an oil discharge cavity, and the volume at the rear side becomes larger. When the connecting line passes through the two tooth roots of the rotor, the oil inlet ends and the largest tooth cavity appears. When the connecting line passes through the two tooth tops of the rotor, the oil drainage ends and the smallest tooth cavity appears. In order to ensure the continuous rotation of the rotor, it is necessary to have the same regular oil distribution mechanism to cooperate with it, so that the tooth cavity at the front side of the connecting pipeline is always connected with the oil drain port, and the rear side is connected with the oil inlet port. As mentioned above, the oil distribution mechanism consists of a housing and an oil distribution sleeve. The 12 longitudinal grooves (x) on the oil distribution sleeve and the 12 intervals formed by the oil distribution groove face the root and top of the rotor through the positioning device, which proves that when the largest and smallest cavities occur, the oil distribution hole of the housing can be closed, thus separating the oil inlet groove and oil outlet groove of the oil distribution sleeve.

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 Cycloidal hydraulic motor with brake 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 Guangdong Cycloidal hydraulic motor with brake 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.
