Maintenance of horizontal multi-stage pump can not only reduce the occurrence of failures and accidents, but also improve the efficiency and reliability of the pump. Therefore, we must attach importance horizontal multistage pump The maintenance work ensures that it can run stably for a long time and provide reliable support for production and engineering.

Horizontal multi-stage pump is a common and widely used in the industrial field of equipment, it plays an important role in fluid transportation. In order to ensure the normal operation of the horizontal multi-stage pump and extend its service life, the correct maintenance is very important. First of all, regularly check the inlet and outlet valves of the pump to ensure that it has good sealing and no leakage. Secondly, clean and replace the filter regularly to prevent impurities from entering the pump and prevent blockage and damage. In addition, pay attention to adding the right amount of lubricating oil or grease to the pump to maintain the normal lubrication of the pump components and reduce wear and friction. In the course of work, it is necessary to regularly observe the operating status of the pump, such as temperature, noise, etc., and deal with abnormalities in time. In addition, it is necessary to regularly check the motor and power supply circuit to ensure the normal operation of the electrical part. Finally, after long-term suspension or seasonal use, the pump should be fully inspected and maintained, including cleaning, lubrication, and corrosion protection.

Next, Hunan Sanchang Pump Industry will explain to you what are the maintenance steps of the horizontal multistage pump:

1. Start the motor. When the pump is running normally, calculate the outlet pressure gauge and inlet vacuum gauge, and then see that it shows the appropriate pressure, gradually open the gate valve and check the motor load at the same time.

2. Try to control the flow and head of the pump within the range indicated on the label of the horizontal multi-stage centrifugal pump to ensure that the pump runs for a long time near the high efficiency point, so as to obtain a large energy-saving effect.

3. Check whether the joint between the pump and the pipeline is loose. Turn the pump by hand to see if the pump is flexible, and then observe the motor turning.

4. When you want to stop using the pump, the first step is to close the gate valve and pressure gauge, and then stop the motor.

5. During the operation of the horizontal multi-stage centrifugal pump, the temperature of the bearing should not exceed 35 degrees of the ambient temperature, and the high temperature should not exceed 80 degrees.

6, horizontal multistage centrifugal pump in the first month of operation, the need to replace the lubricating oil after 100 hours of work, after every 500 hours to replace the lubricating oil.

7. When stopping the use of the pump, it is necessary to close the gate valve of the outlet pipe, the outlet pressure gauge and the inlet vacuum gauge.

8. If the horizontal multistage centrifugal pump needs to be deactivated for a long time, the pump must be disassembled, the water dried, the rotating parts and joints are lubricated and stored correctly.

9. Add bearing lubrication engine oil to the suspension, and pay attention to the oil level should be between the two engraved lines on the oil mark.

10. When using a horizontal multi-stage centrifugal pump in a cold winter, after stopping, the drainage plug at the bottom of the pump body must be opened to drain the water clean to prevent freezing and cracking.

11. If abnormal sound is found in the horizontal multi-stage centrifugal pump, please stop immediately and check the cause.

12. When filling water, it is necessary to unscrew the water diversion plug of the pump body.

13. Regularly adjust the packing gland to ensure that the leakage in the packing chamber is normal.
