What are the factors that affect the life of hydraulic motors? Dalan motor manufacturers tell you that the eight reasons that affect the life of hydraulic motors are as follows: 1. Bearing wear 1 Bearing wear is the decisive factor affecting the soft life of the motor. 2 Bearings used in motors are special bearings that carry specific frictional moments under specific operating conditions. 3 can not be replaced by non-professional bearings, otherwise the motor can not work properly and greatly reduce the service life of the motor. 2, motor speed 1 motor speed is related to the life of the motor, durability, cavitation and noise, motor speed should be selected in strict accordance with the technical data, must not exceed the maximum speed value. 2 Within the permissible speed range, the optimum speed should be selected according to the working conditions, and the minimum speed should not be lower than 50r/min. 3. Drainage pressure in the motor casing The pressure of the drain in the casing depends on the maximum pressure allowed by the shaft seal, generally 0.2 MPa. If the casing discharge pressure is too high, the shaft seal will be damaged prematurely. 4. Connecting different shafts When the shaft axis of the pulley shaft and the motor shaft are different than 0.1mm, the vibration generated by the high-speed rotation will be directly reflected on the motor spindle bearing, reducing the service life of the spindle front end bearing. 5, suction cavitation 1 When the main oil pipeline and component joint seal has a small failure range, the main engine hydraulic pump will draw air from the failed part, so that the high pressure oil entering the motor contains air bubbles, squeezed in the oil Under the action, the bubble bursts and ruptures in the motor cylinder, causing the cavitation of the cylinder. When the cavitation is severe, the copper layer interval of the cylinder distribution surface will collide. 2 Another reason for inhaling air is that the volume of the hydraulic oil tank is small or the design of the partition plate in the fuel tank is unreasonable. When the hydraulic system is returned to the oil, the air bubbles in the oil are not completely eliminated and are sucked away by the pump suction port. 6. Hydraulic oil pollution 1 The pollution is mainly caused by human pollution. When the hydraulic filter element is replaced, the oil in the filter cartridge is not drained or the oil in the filter cartridge is not discharged, and the filter element is replaced, causing pollutants in the filter cartridge. Directly flow into the tank from the discharge port of the filter cartridge. 2 When a particle larger than 10μm enters the motor, it will cause a scratch on the distribution surface. This scratch will become a groove under the long-term flushing of the high-pressure oil. This groove is enough to cause the motor. Invalid. 7. Operating environment The operating environment also affects the condition of the hydraulic motor. Eg: During the cutting operation, the main engine, the tool and the frame will generate large vibrations, which will damage the hydraulic motor components. 8. Maintenance method 1 Any improper maintenance method will cause damage to the hydraulic motor. 2 The disassembly and assembly of the hydraulic motor is a delicate and complicated and professional work. The maintenance personnel must carefully read the maintenance instructions of the motor and adjust the static bearing clearance according to the regulations. ----- Responsible Editor: Dalan Oil Pump Motor 02- Purchasing Consultant Copyright http:/(Dalan Motor) Reprint, please indicate the source http://news.chinawj.com.cn
