First, the fire pump installation preparation matters Fire pump cable should be intact;
2. The insulation resistance of the motor should be greater than 50MΩ;
3. There should be no loosening of the fasteners, and the motor barrel should be intact;
4. The guide rod should be fastened firmly, otherwise it will affect the normal operation of the fire pump.
Second, the installation of fire pumps 1. Fire pump lifting should use stainless steel chain, and has been placed on the pump set screw;
2. The fire pump and its matching control cabinet are reliably grounded;
3. Because of the high water pressure of the fire pump, the pump is not adapted to the match. The fire pump outlet is hard-wired with a metal hose or steel pipe. The length of the pipe connected to the pump outlet must extend out of the cover plate of the pool.
4. Fire pump outlets should be equipped with hose check valves, etc.
5. The pump outlet pipe shall support the ground so as to avoid deformation or damage of the fire pump.
Third, the fire pump test:
1. When the fire pump is commissioned, if it finds that the pressure cannot reach the specified requirements, the motor may be reversed, and any phase sequence in the three-phase wire may be exchanged. If the pressure is low and unstable, the fire pump outlet pipeline shall be subjected to deflation treatment;
2. When the fire pump is running, the outlet valve should be adjusted so that the outlet pressure during operation reaches the rated requirement, otherwise the effect of fire will be affected or the fire pump will be overloaded.
