How to stop the diesel engine fire pump correctly

1. After the diesel water pump outputs the foam mixture, it should be immersed in clean water for 2 minutes to clean the pump body parts and avoid the residual foam liquid corrosion.
2. When stopping, close the small throttle, let the engine idling for 2 minutes to make the cooling uniform, and then accelerate the idling for 2-3 seconds to make all components fully lubricated and then stop.
3. After stopping, disconnect the circuit and remove the key. If the pump room has no insulation measures, and the indoor temperature is below 5℃, all engines and water pumps should be stored everywhere in winter to prevent freezing and cracking of components.

   

4. When the engine discharges to water, open the heat exchanger with a water cover, and then turn on the heat exchanger and its water tank drain switch to drain the water from the cooling system.

Note: The battery should always be adequately powered.
