2 Diesel Engine selection

2.1 The selection of diesel power rating should be greater than 10% of the maximum pump shaft power, under

abnormal conditions of engine power will be less than the rated power. For proper operation, it should be used

in high power diesel engine and pump support.

NOTE: Diesel engine 12 hours power in the state when the following criteria measured:

Atmospheric pressure is 100KPa;

Ambient temperature 25 ℃

Air relative humidity 30%

Working to improve the ambient temperature every 5 %, its power decreased by 1% (to 25 % as the base);

Work to raise the altitude of 100m, its power is reduced by 3%;

Actual output power of diesel engine=（CA+CT-1）×12 hour power

CA—-Altitude Correction Coefficient

CT—-Ambient Temperature Correction Coefficient

Diesel engine for large flow, high pressure pump should consider the impeller rotor parts with the water moment of inertia calculation.

1. spectrum range: fire pump can use a single-stage end suction pump, a combination of multistage single-suction

pumps, single-stage double-suction pumps and other kinds of pumps, pump or more kinds of parallel flow, wide

pressure range;
2. automatically: When the engine fire pump receives a valid signal fire, remote control start signal when the unit

will start automatically; when the fire pump motor supply failure or lack of signal phase, the unit will automatically

standby. Diesel fire pump start 10s, if not start running, stop 10s, and then restart. The unit will automatically
repeat three times.

3. Alarm System: repeatedly failed to start alarm, low diesel engine oil pressure alarm, ultra-high temperature alarm

diesel engine, diesel engine speed alarm, low battery alarm, charging failure alarm, an alarm indicating a lack of fuel.

4. kinds of ways to start: signal fire started, manually start or remote start.

5. direct-attached: Automobile universal joints, high transmission efficiency, large torque diesel engine vibration isolation.

6. automatic charging: use electricity charge, usually in the automatic standby position, if the battery voltage is low,

the unit automatically charging; When the battery voltage is adequate, can automatically stop charging to avoid

damage to the battery.
