The oil mud pump routine maintenance methods and precautions
1. Main items before pumping
Avoid frequent pumping before pumping, and prevent vaporization of the pump during pumping and pumping. Moreover, when the high temperature liquid is delivered in a cold state, it is not allowed to start the multistage pump operation urgently. The reason is that when the transported high-temperature hot liquid reaches the multi-stage cold-state pump body, the temperature of the pump body will change greatly due to the high-temperature hot liquid, which will cause the pump body to be heated unevenly, and the pump body Deformed with the rotor.

2. The main matters of the pump in operation
If it is a mud pump that balances the axial force by a balancing mechanism such as a balance plate, in order to ensure the normal operation of the pump, there are the following points.
First, the balance balance tube connecting the balance device and the inlet end of the pump should not be blocked. If it is found that there is scale inside the tube, it should be cleaned in time. Secondly, the pressure gauge should be installed on the high pressure side of the balance tube to check the pressure at the outlet of the balance tube.

3. Precautions after stopping the pump
When the oil slurry pump stops working, the weight of the impeller and the rotor will force the pump shaft in one direction, which will easily cause the shaft to bend. The pump should be inspected regularly.

4. Disassembly and repair of oil slurry pump
When disassembling or repairing the oil slurry pump, the operator must be proficient in the structure of the mud pump. And prepare the tool in advance when disassembling or repairing. During the transfer, care should be taken to clean the parts of the pump and then transfer them according to the structure. The transfer should be careful and there should be no loss. Check it after the transfer. See if it has been fully transferred.

5. Pre-assembly check notes
For multi-stage pumps, the number of parts must be checked before pre-assembly. The operator should understand the installation sequence. For example, for multi-stage pumps, the rotor part should be assembled first, in order to check the concentricity and skewness of the rotor. The distance from the impeller outlet. Be sure to calibrate the pump shaft first, then install the impeller and balance plate on it, and finally lock it with the bushing and install it on the top of the lathe or on the v-shaped iron.
