In the most common cases, the generator tank, also called a service tank or daily tank, can be placed under the engine-alternator coupling, incorporated in the basement of the enclosure or in the installation room, on the floor or on the wall. In any case it has at least one of these elements that has to be maintained:
· Visual analogical level gauges
· On-off floater or with more level
· Solenoid valve or toggle valve
· Fuel pumping system which can be manual, electrical or both
It is good to check, especially for older installations, that there are no damps from joints or welds. If there’s the visual level gauge then check that there are no leaks from the seals or cracks in the glass.
If a manual pump is present, it is sufficient to test its operation and to check that there are no fuel leaks during the crank movement.
In the presence instead of an electric pump it is possible to force the start, if allowed, or to simulate the automatic start removing the float from the tank in order to check its integrity and to make sure that the level alarms and the automatic start of the pump respond.
Even in this case there must be no fuel leaks from the pipes during operation, otherwise you must restore immediately.
“After how long should the fuel pipes be replaced?”
The production date may be printed on the pipe, but not the expiration date as this depends on how the tube is used (temperatures, atmospheric agents…)
However, there is an indication of duration, which is about 10 years, but linked to the conditions indicated above.
The whole system can also be easily tested by simulating a tank emptying if however it is supplied with an emptying system with tap and collecting tank.
The operations described above are carried out with the generator switched off and the control unit in OFF position.( Possibly also disconnecting the battery)
Leakage collection tank of the Generator
The collection tank, if present, must be kept clean in order to highlight any liquid leaks.
If a drainage point is present, check for leaks and if it’s not has been tampered with.
