Which test maintenance should be done after the diesel generator set?

Summer is coming,Diesel generators组In the peak period of use, what tests need to do for half a year's diesel generator set? The star / diesel generator set is to tell you, the general thing is to check the following:
1. Check the startup of the unit
Test method: The test should be 5 min, and then a 50% rated load of 1.0 is 5 min after the startup command is initiated, and then stopped.
Test 100 times. The start-up success rate should be greater than 99%. Otherwise, this is considered unqualified.
2, check the average fault interval of the unit
Checking method: The unit with COSф = 0.8 rated load, continuous or accumulated operation 1000h or more, diesel engine, generator should not malfunction, the component of the control circuit should not appear twice or more, otherwise, this is considered unqualified.
This indicator allows for assessment in actual operation.
3, check the operation of the unit with the capacicy silicon load
Test method: The three-phase controllable silicon rectifier load with COSф≥0.5, and should be able to stabilize at any point in the range of 10% to 50% of the unit rated capacity.
If low-frequency oscillation is generated, adjustment should be adjusted, so that it can work, otherwise it is not qualified.
4, check the linkage test of the automation unit
Checking method: The two units should be mutually alternate, optionally a primary use, and artificial cut off the main unit, and the main unit is automatically activated. Manufacturing a fault makes the main unit automatic shutdown standing unit should be automatically successful. Enable the city's battery constant, the standby unit is automatically stopped.
If you fail, find out the cause, troubleshoot. The two units are the main use and re-test three times. If there is still no qualification, this is not qualified.
5, check the automatic start function of automated diesel generator set
Test method: Turn on the start of the power supply, select the unit to select the switch to move to automatic, send the start command, and the unit is unsuccessful, and the unit should start three times.
Three times of test, as long as there is no qualified, the number of times the retest is doubled, and if there is still no qualification, this is not qualified.
6, check the automatic supply device of the automation unit
Test method: After the control circuit circuit is completely coupled, the working mode selection switch moves to the automatic person to put water to the low level, which should be automatically supplied, and the supply should be automatically stopped when the liquid rises to high levels
Three times of test, as long as there is no qualified, the number of times the retest is doubled, and if there is still no qualification, this is not qualified.
7, check the protection of automation units
Test method: the oil pressure is low, cooling water temperature is high protection, and the simulation method is taken; overvoltage protection takes a method of adjusting the output voltage; the short-phase protection takes a method of disconnecting the person; overload protection takes a way to increase the load.
Each protected test three times, as long as there is a failure, the number of times the retest is doubled, and if there is still a fail, it is considered that this item is unqualified.
8, check the cooling water of the automation unit, the oil heating
Test method: Turn on the power, the heater should be heated if the temperature of the water is less than 15 ° C, and when the temperature reaches 50 ° C, the heater should stop heating.
Turn on the power, the heater should be heated if the temperature of the oil is below 15 ° C, and the heater should stop heating when the temperature reaches 30 ° C.
Each test three times, as long as there is no qualified, the number of times the retest is doubled, and if there is still a fail, it is considered that this item is unqualified.
