Diesel engine fire pump maintenance 1

1. The proper maintenance of the diesel engine fire pump, especially preventive maintenance, is the easiest and most economical maintenance, so it is key to prolong the service life and reduce the use cost. The following steps can be taken to check the fuel consumption of the fuel tank to observe the fuel tank consumption, according to the need to add.

2. Check the oil level in the oil pan to see if the oil level reaches the mark on the oil scale. If it is insufficient, it should be added to the specified amount, but not above the upper limit of the scale.

3. Check the fuel injection pump governor oil plane if you do not meet the specified marking mark, should add enough oil (some fuel injection pump governor without the ruler, you can save this step).

4. Check whether there is sufficient grease in the oil filling point of the pump to remove the oil filler from the diesel pump on the circulating pump to see if the grease inside is sufficient, if enough, apply the oil gun to fill the inside with sufficient grease.

5. Check the antifreeze in the tank is sufficient to find the water tank in the antifreeze should be added in time to add the antifreeze should be the same brand of the same model. or according to the local minimum temperature configuration appropriate freezing point of the antifreeze, glycol antifreeze formula is as follows:

Ethylene glycol	Water	Solidifying Point
60%	40%	-55℃

Ethylene glycol	Water	Solidifying Point
55%	45%	-40℃

Ethylene glycol	Water	Solidifying Point
50%	50%	-32℃

Ethylene glycol	Water	Solidifying Point
40%	60%	-22℃
