1, after opening, first of all should check the running current of the electric motor, including seeing the running function of the water pump is normal, once breakdown, must stop immediately.
2. Observe the pressure gauge and see that the pointer on the gauge shows that it is at the rated working pressure. Open the valve and wait until it does not fluctuate. Then slowly open the gauge. In order to ensure safety and long-term use, the instrument should be kept stable in all aspects of work.
3. When there is no fault in the pump water check, move the clutch lever on the pump to the place where “minutes†are displayed.
4, the pressure of the valve group should be stable, and to maintain a certain value, preferably 0, 8mpa or so, if the pressure can be adhered to, it can be normal operation, but if the pressure is difficult to adhere to, you need to properly regulate the export, so that The pressure reaches the required conditions.
5, the temperature of the water pump is very important, including the temperature of the motor bearing, can not be ignored, the maximum temperature can not exceed 75 degrees, so when not in use should always insist on inspection to ensure that the temperature and operating current are within the normal range .
6. When the pump is stopped, it should be restored to its original state. This step can be implemented according to the pump's own valve switch indication diagram.
7. After determining that there is no other fault after the fire pump is stopped, the clutch handle can be moved to the “closed†position. At this time, it has not been completely operated. The open air valve should also be turned over to allow the float to return to reset. The use of time.
What are the steps for using the fire pump?
Fire pumps are placed in many places, which are necessary for urban facilities. But many people do not know how to use it, which makes these fire tools have become a kind of decoration. We can learn a little bit about it, and when it's time to use it, it won't be so lost. The use of fire pumps mainly involves several steps:
