Maintenance
1. Bearing lubrication
The function of the bearing box is lubricating and cooling. As with the car, the new pump also has the period of running in. Please use and replace the lubricating oil correctly according to the use manual. (pay attention to do not enter impurities in the bearing box)
2. The disassembly and disassembly of the pump
All parts of the rotary jet pump have strict size matching requirements. Please use the correct way and method when assembling and disassembling, do not barge and disassemble, so that the accuracy of each part of the pump will change and affect the operation and use of the pump.
3, the middle of the pump and the motor
When maintaining the rotary jet pump, such as loosening the screw between the base and the pump or the base and motor, please calibrate it according to the requirements of the manual, so as not to cause vibration, abnormal noise, motor current and so on, thereby indirectly affecting the service life of the pump group.
4. The correct use of the machine seal
The requirements for the sealing are different in different working conditions. Please select the machine seal correctly according to the actual working conditions. Please refer to "machine seal installation instructions" in "data download" for the installation and use of the machine seal.
5. How to adjust the pump pressure without changing all the components of the pump
Note: a series of problems will be caused by the use of the pump ordering without permission, and the user must not change it by itself! The following method is knowledge popularization, users
In case of use, it must be permitted by the manufacturer in advance.
A, by increasing the flow of pump through reflux, this method is often used to reduce pump pressure. But in practical operation, if the motor is not selected enough allowance, it will cause motor overload trip or fever burn out. And we need to pay attention to the flow of the pump can not exceed the maximum flow rate of the pump, otherwise it will cause the damage of the pump.
B, changing the speed of pump. This method is mainly used to reduce or increase pump pressure. But if we increase the speed, we must consider the material strength of the pump. If the material strength is not allowed, it is forbidden to increase the speed operation. When the speed is changed, the flow will also change slightly. The flow volume can be adjusted by adjusting the valve, but if we reduce the speed, we must notice that the maximum flow of the pump will also decrease.
6. The disassembly and disassembly of the bearing
The bearing of the rotating jet pump is closely matched with the shaft, and the bearing is loosely matched with the pump body. In the process of bearing disassembly, the bearing can only be made to the inner ring of the bearing.
7. Selection of lubricating oil for bearing
The function of the bearing box is lubricating and cooling. As with the car, the new pump also has the period of running in. Please use and replace the lubricating oil correctly according to the use manual. (pay attention to do not enter impurities in the bearing box)
