　　What preparations should be made before installing a fire pump

　　After opening the box, check whether the installation box matches the supply name, specifications, spare parts, and special tools specified in the contract.

　　2. Check whether there is any obvious deformation or damage to the parts of the whole machine during handling, transportation, and storage, and whether the fasteners are loose or detached.

　　3. Check if the entrance seal of the junction box cable is intact, and promptly and properly handle any possible leakage or poor sealing.

　　4. Check if the oil chamber of the guide vane body is filled with oil, and the oil in the chamber should be added until the oil injection hole is visible

　　5. Use a multimeter to check the resistance of each phase in both high and low states, and the values should be close to equal; Check if the grounding wire is reliably grounded.

　　6. Rotate the impeller. Check whether the reciprocating components are flexible and free of jamming phenomenon

　　7. Check if the connections between the oil-water probe, float switch, heating sensor, and distribution cabinet are effective and normal.

　　8. Check whether the concrete foundation is solid and flat.

　　9. Power on and run the water pump in an empty state. Check the direction of rotation of the water pump, which appears to be clockwise when viewed from the motor end. Otherwise, switch the positions of the two phases at the power connection. At the same time, the identification of the main cable and power interface should be recorded to prevent adverse consequences caused by reverse rotation after diving.

　　10. Determine the installation elevation. The installation elevation is very important and should comply with the values determined by the design, and should not be changed without authorization.

　　The above points are a brief summary of the preparation work that fire pump manufacturers need to do before installing fire pumps. We hope it is helpful to you. If you have any questions about fire pump production, please feel free to call us for consultation at any time!
