English
5 Check the efficiency of the electronic control panel
6 Check the efficiency of the control panel alarm LEDs
7 Check the efficiency of the minimum tank/cistern/well level alarm
8 Check electrical connections ensuring there are no burns, no damage to the insulation and no loosened screws on the terminal boards
10 Check the preloading of the diaphragm tanks
13 Check the efficiency of the minimum fuel level alarm
14 Check the efficiency of the motor oil heater
15 Check the battery charge level and efficiency of the battery charger
16 Check the efficiency of the stop electromagnet
17 Check the viscosity and level of the pump cooling oil
18 Check the efficiency of the priming circuit (especially if there are units with suction lift)
During all checks, make a notice of the following:
19 a) all pressure readings on the water and air pressure gauges (plant, main conduits, and pressurized tanks);
20 b) all water levels in private elevated storage tanks, rivers, canals, lakes, storage tanks (including pump priming tanks and pressurized tanks);
21 c) the correct position of all the main On/Off valves
Automatic start-up test
The following aspects of the automatic pumps must be checked and tested:
22 a) check the fuel and lubricant oil levels in the diesel motor;
23 b) lower the water pressure in the start-up device to simulate automatic start-up conditions;
24 c) check and record the pressure when the pump starts;
25 d) check the pressure of the oil in diesel motor pumps
e) check if the water flow through the heat exchanger (if present) is adequate
Diesel motor restart test
Check the diesel motors immediately after the preceding pump start-up test:
26 a) Let the motor run for 20 minutes at rated duty point. Stop the motor and then immediately start again using the manual start-up test button;
27 b) Check the water level in the primary circuit of the closed-circuit cooling system.
Check the oil pressure (read on the pressure gauges), the motor temperature, and the coolant flow during this test. Check the oil pipes and
inspect the plant generally for leaks (fuel, coolant, or exhaust fumes).
28 Check the inlet system/ventilation (air filter, operations, obstructions)
Monthly checks
š
1 Check the level and density of the electrolyte in all cells of the lead battery (including the diesel motor start-up batteries and those used
to supply the electronic switchgear).
2 If the density is low, check the battery charger and, if this is efficient, replace any battery or batteries not in perfect condition.
3 Check for corrosion of diesel motor battery terminals and conditions of cable lines and connections.
Quarterly checks
š
An inspection report must be signed, dated, and handed over to the end-user. This must include details of all work carried out or required
and any external factors that can affect the results, such as the weather, etc.
1 Check the pipes and supports for corrosion and, where necessary, paint them.
2 Check the pipes for proper earthing. Do not use the sprinkler pipes to earth the electrical equipment. Remove all earth connections on these
and make alternative connections
3 Check all the water supplies at each control station in the system. All pumps must start automatically and the minimum pressure and flow
rate values must not be lower than the nominal values in the project. Record all changes
4 Test all On/Off valves that control the water flow to the sprinklers to make sure that these work properly and then return the valves to their
normal position. Do the same for all the water supply On/Off valves, the control, and alarm valves and all local or auxiliary On/Off valves.
5 Check the efficiency of the flow switches.
6 Check the quantity and condition of all spare parts held in stock.
Six-monthly checks
š
1 Check the alarm system and remote alarm system in the central control unit.
1 Check coupling alignment
Yearly checks
š
1 Test the efficiency of every pump when fully loaded (connect the test line to the pump delivery circuit) and make sure that the pump pres -
sure and flow rate values match those on the rating plate.
Consider any loss in pressure in the supply lines and valves between the water supply source and each control station unit.
2 Test the diesel motor for non start-up and check that the no start-up alarm works, in compliance with the requirements of the applicable
standard. Then start the diesel motor again using the manual start-up procedure.
3 Check the efficiency of the float valves in the storage tanks
4 Inspect the suction filters in the pumps and deposit chambers fitted with filtering panels; clean if necessary
5 Change motor oil and filters (oil and fuel)
