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 Lishui Sweeper cycloidal hydraulic 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 Sweeper cycloidal hydraulic motor Large emissions, relatively small impact of leakage, large rotation inertia of the motor itself, easy to obtain good low-speed stability.
Causes: 1. The pump is damaged, and the pump body is overheated and produces noise. 2. The control valve is closed tightly or the oil supply and return system is blocked, and local overheating occurs. 3. The safety valve is opened, and the valve cries or hisses, and local overheating occurs. 4. The distribution rotary valve is excessively leaking, and the valve chamber is overheated, and it is very hot when touched by hand. 5. The hydraulic motor crankcase is excessively leaking, and the single oil drain pipe is leaking want to buy Sweeper cycloidal hydraulic motor Treatment method for excessive leakage and high oil level: 1. Check the condition of the ball joint 2. Check the sealing condition of the cylinder piston 3. Check the viscosity and operating temperature of the oil 4. Check the contact surface between the oil pan and the housing 5. Check the surface between the connecting rod and the eccentric wheel Sweeper cycloidal hydraulic motor Price 6. Check the wear of the oil pan and whether the two oil cavity channels at the inlet and outlet of the casting are connected
1. Generally, the motor shall be able to run forward and backward. Therefore, the hydraulic motor is usually required to have structural symmetry in the design. 2. The actual working pressure difference of the hydraulic motor depends on the load torque. When the moment of inertia of the driven load is large and the speed is high, rapid braking or reverse rotation is required, high hydraulic impact will be generated. Therefore, the system should be equipped with necessary safety valves and buffer valves. 3. Under normal working conditions, the inlet and outlet pressure of the hydraulic motor is higher than the atmospheric pressure, so there is no suction performance problem like the hydraulic pump. However, if the hydraulic motor can work under pump conditions, its oil inlet should have a minimum pressure limit to avoid cavitation. 4. Some hydraulic motors must have sufficient back pressure at the oil return port to ensure normal operation. The higher the speed, the greater the back pressure, which indicates that the utilization rate of oil source pressure is not high and the system loss is increased. 5. Because the internal leakage of the motor is inevitable, there will be slow sliding when the hydraulic motor oil outlet is closed for braking. Therefore, when long-term accurate braking is required, a separate anti-skid brake shall be set.
Of course, you can increase the traffic want to buy Sweeper cycloidal hydraulic motor 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 Lishui Price Ming can try, and consult the cycloid hydraulic motor expert if he thinks the error is found.
(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 Lishui Sweeper cycloidal hydraulic 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 Sweeper cycloidal hydraulic 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.
