Performance test of generator unit may need more than a test, a comprehensive analysis of multiple content detection, after all qualified qualify the performance of diesel engine.

1, inspection unit automation, automatic start function

Test method: connect the starting of the power supply, will work mode of unit selection switch to automatically move, into the start command, and anthropogenic causes the unit to start is not successful, the unit should automatically restart three times. The three test, as long as there is an unqualified, re double the number, if there is still an unqualified, think this is not qualified.

2, inspection unit automation unit's cooling water, oil heating

Test method: switch on the power, if the water temperature is lower than 15 DEG C heater heating, when the temperature reaches 50 DEG C heater stops heating. Switch on the power, the oil temperature below 15 DEG C when the heater heating, when the temperature reaches 30 DEG C heater stops heating. Three of the test, as long as there is an unqualified, re double the number, if there is still an unqualified, think this is not qualified.

3, inspection unit start-up success rate

Test method: the test shall be in accordance with the provisions of the product technical conditions of preparing to start state, each to a start command, after a successful start-up sudden power of 1 50% of the rated load running 5min, stop. The 100 test, launch success rate should be greater than 99%. Otherwise, think this is not qualified.

Automatic supply device 4, check the automation unit

Methods: in the control circuit completely after completion of coupling, the working mode selecting switch moved to automatic human drainage oil to low level, should be able to automatically recharge, when the liquid level rose to a high level when the supply should be able to automatically stop. The three test, as long as there is an unqualified, re double the number, if there is still an unqualified, think this is not qualified.

The operation situation of 5, inspection unit with silicon controlled rectifier load

Test method: unit with cos diameter greater than or equal to 0.5 of a three-phase silicon controlled rectifier load, rated capacity in unit 10% to any point within a range of 50% shall be capable of stable operation. If produce low-frequency oscillation, should carry out the adjustment, so that it can work stably, or that this is not qualified.

6, inspection unit, mean time between failures

Inspection methods: unit with cos ~ =0.8 rated load, continuous or accumulated running above 1000h, diesel engine, generator should not appear the fault, control circuit components should not appear more than two times of fault, otherwise, is that this is not qualified. This index allows for assessment in the actual operation.
