ONE. Preparation before operation of fire truck
1. Check the lubricating oil level in the bearing housing and the suction pump, if it is insufficient, it should be supplemented.
2. Close all drain cocks and valves.
TWO. Fire trucks divert and inject water
1. When using the water in the pond, remove the suction pipe, connect one end to the suction port of the pump, connect the other end to the water filter and put it into the pond, close the water inlet butterfly valve, open the water intake valve, and then the water tank can be sent to the water tank. Water injection.
2. When using the water in the fire hydrant, connect the fire hydrant to the water injection port outside the water tank with a hose, and inject the water directly into the water tank.
THREE. The fire truck comes out of the water
When the fire truck uses the water in the water tank, open the rear water inlet butterfly valve, start the fire pump, and perform the following operations:
1. Low pressure water outlet
After the fire pump works, open the low-pressure water outlet ball valve to realize low-pressure water outlet
2. Water from the gun
When working at low pressure, close the low-pressure water outlet ball valve and open the gun ball valve to achieve fire-fighting with gun outlet water.
FOUR. Precautions for fire trucks
1. After the water pump of the fire truck is used, turn on all the residual water switches on the pump to discharge the residual water in the pump. After the residual water is discharged, close all the switches to facilitate antifreeze and next use.
2. After the water pump has been used with seawater, sewage, corrosive water flow and foam mixture, run it with clean water for more than 1min to clean the residual liquid in the pump.
3. Regularly check the lubrication condition in the bearing, if it is lower than the oil level, it should be supplemented.
4. After using the fire truck fire pump in winter, run the piston pump several times to drain the remaining water in the piston pump to prevent the formation of troops.
5. The water pump is strictly prohibited from idling without water for a long time (more than 1min)
