The steps to start and stop the pump for the fire pump are as follows:
1. After starting the pump, check the running current of the motor and the normal operation of the pump. If there is any abnormality, stop the pump immediately.
2. Check the pressure gauge at the pump outlet. When the gauge pointer reaches the rated working pressure and stabilizes, gradually open the outlet valve and try to make the pump work under the rated condition.
3. After the pump is normally watered, move the vacuum-mounted clutch handle to the “minute†position.
4. Check the pressure of the valve block. The pressure of the clean water valve group is about 0.8Mpa, and the foam valve group is about 1.0Mpa. If the pressure cannot be adhered to, the pump outlet and return valve control pressure can be properly adjusted.
5, should always check the temperature of the pump and motor bearings, the maximum temperature can not exceed 75 degrees, check the operating current of the motor should be within the normal range.
6. After stopping the pump, return all the valves to the normal state according to the valve opening and closing status.
7. Move the vacuum-loaded clutch handle to the “closed†position, open the air valve, and let the float assembly reset, in a state of preparation.
8. If the pressure reaches 0.8Mpa immediately after the pump starts, it can return to 0.4Mpa immediately. It can't be discharged normally. At this time, stop the pump immediately, turn the valve open and let the float assembly reset and restart.
Fire pump maintenance and maintenance
1. Check and ensure that the power supply and circuit of the fire protection system are smooth and the electrical equipment is in good condition.
2. Once every shift, the coupling should be light and heavy, no abnormal noise and record.
3. Check the smooth oil level in the vacuum installation on the 5th, 10th, 15th, 20th, 25th and 30th of each month. The fueling position is at the center line of the oil window or slightly lower than the center line; start the fire truck fire truck fire pump, Check the pump water time and make a record. The 1# and 2# pumps run for 15 minutes, and the 3# and 4# pumps run for 5 minutes.
