3. When the pump starts, check and record the starting pressure.
4. Check the oil pressure of the diesel pump and the water flow rate in the cooling
circuit.
CAUTION
Malfunction due to missing operating fluids!
Always refill the fuel and other fluids after these checks.
8.3
Diesel pump automatic start test
After the starting test perform the following checks on the diesel motor:
1. Leave the motor running for 20 minutes or the time recommended by the manu-
facturer. Then switch off the motor and restart it immediately using the "manual
start" button;
2. Check the water level in the primary cooling system.
During the test it is necessary to check the oil pressure, motor temperature and coolant
flow rate.
Then check the oil hoses and carry out a general inspection for any leaks of fuel,
coolant or exhaust fumes.
8.4
Periodic checks
WEEKLY CHECKS
1. Check ventilation and room temperature.
2. General inspection of the unit (including electrical and water supplies) to check the
apparent state of all components (no leakage).
3. Carry out general cleaning.
4. Check the tightness of the check valves.
5. Check that the switchgear is in auto-start mode.
6. Check the efficiency of the electrical switchgear.
7. Check the efficiency of the switchgear alarm LEDs.
8. Check the efficiency of the minimum level alarm of the tank/tank for fire-fighting
purposes/level well.
9. Check the electrical connections for burns, insulation damage and loose screws on
the terminal blocks.
10.Check the preload of the expansion vessels (if any).
11.Check the efficiency of the minimum fuel level alarm.
12.Check battery charge level and charger efficiency.
13.Check the efficiency of the stop solenoid.
14.Check the viscosity and coolant oil level of the pump.
15.Check the suction pipe. The water must flow in without air pockets, check venting
devices.
During all checks, take note of the following:
ƒ
all pressure readings on water and air pressure gauges (system, main ducts and pres-
sure tanks)
ƒ
all water levels in the water supply such as rivers, canals, lakes, storage tanks (in-
cluding pump priming tanks and pressurised tanks)
ƒ
the correct position of all main valves on/off
Automatic start test
The following aspects of automatic pumps must be checked and tested:
1. check the fuel and lubricating oil levels in diesel engines;
2. lower the water pressure in the starter to simulate automatic start conditions;
3. When the pump starts, check and record the starting pressure.
