Inspection Standard Of Volvo Diesel Genset After Production

Jan. 21, 2022

After production, can Volvo diesel generator be put into operation normally and meet relevant standards? 


A.The following tests are carried out on the test bench of Volvo diesel generator:

1. Visual inspection

2. Measurement of resistance

3. Startup performance test at room temperature

4. No load voltage setting range

5. Measurement of voltage, frequency, voltage regulation rate and fluctuation rate

6. Record of rated load operation for two hours and 10% 1 hour

7. Determination of stability time of sudden application of 50% 0.8 load and 100% 1.0 load.


Inspection Standard Of Volvo Diesel Genset After Production


B.10 standards for Volvo diesel generator inspection.

1. Appearance requirements.

(1) The installation dimension and connection dimension shall comply with the factory drawings approved by the specified procedures

(2) The welding shall be firm, the weld shall be uniform, and there shall be no defects such as welding penetration, undercut, slag inclusion and pores. The welding slag and flux shall be cleaned; The paint film shall be uniform without obvious cracks and falling off; The coating shall be smooth without missing plating spots, corrosion and other phenomena; The fasteners of the unit shall not be loose.

(3) The electrical installation shall comply with the circuit diagram, and each conductor connection of the unit shall have obvious signs that are not easy to fall off.

(4) There shall be well grounded terminals.

(5) Label content


2. Inspection of insulation resistance and insulation strength.

(1) Insulation resistance: the insulation resistance of each independent electrical circuit to the ground and between circuits shall be greater than 2m

(2) Insulation strength: each independent electrical circuit of the unit shall be able to withstand AC test voltage for 1min to the ground and between circuits without breakdown or flicker.


3. Check phase sequence standard.

The phase sequence of the control panel wiring terminals after the production of diesel generator shall be sorted from left to right or from top to bottom from the front of the control panel.


4. Ready for operation status requirements. The Volvo generator shall be equipped with heating device to ensure that the oil temperature and cooling medium temperature during emergency startup and rapid loading are not lower than 15 ℃


5. Check the reliability of automatic start-up power supply and automatic shutdown.

(1) After receiving the start command of automatic control or remote control, the diesel power generation shall be able to start automatically.

(2) When the unit fails for the third time after automatic start, the start failure signal shall be sent; When a standby unit is set, the program start system shall be able to automatically transmit the start command to another standby genset.

(3). The time from the automatic start command to the power supply to the load shall not be 3min

(4) After the automatic start is successful, the load shall not be less than 50% of the rated load.

(5) After receiving the shutdown command from automatic control or remote control, the unit shall be able to stop automatically; For the standby unit used together with the municipal power grid, when the power grid returns to normal, the diesel generator shall be able to switch or stop automatically, and its shutdown mode and shutdown delay time shall meet the provisions of product technical conditions.


6. The success rate of automatic start shall be verified. The success rate of automatic startup shall not be less than 99%.

7. No load voltage setting range requirements. The no-load voltage setting range of the unit shall not be less than 95% - 105% of the rated voltage.

8. Automatic replenishment function requirements. The unit shall be able to automatically charge the starting battery.

9. Automatic protection function requirements. The unit shall be protected against phase loss, short circuit (no more than 250KW), overcurrent (no more than 250KW), overspeed, high water temperature and low oil pressure.

10. Sinusoidal distortion rate of line voltage waveform. Under no-load calibration voltage and calibration frequency, the sinusoidal distortion rate of line voltage waveform is less than 5%.
