What Should Be Included in Commissioning of Volvo Genset

After the installation of the Volvo diesel generator set is completed, it can not be started up immediately. It can only be normally started and used after a full range of commissioning and acceptance. The following Dingbo power will introduce to you what aspects are included in the commissioning and acceptance of the installation of generating set.

I. Unsealing of the unit.

Clean and erase the anti-rust oil outside the unit -- when the unit leaves the factory, in order to prevent the corrosion of external metal, some parts are treated with oil seal. Therefore, the new unit installed, and through the inspection, in accordance with the installation requirements, must be unsealed to start.

II.Unit inspection.

i.Check whether the surface of the unit is completely cleaned and whether the anchor nut is loose. If any problem is found, tighten it in time.

ii. Check the cylinder compression force, rotate the crankshaft to check whether there is any abnormal sound in the operation of the cylinder parts, and whether the crankshaft rotates freely. At the same time, pour the oil pump into the friction surface, and manually pry the crankshaft, it feels very difficult and there is counter-thrust (elastic force), indicating that the compression is normal.

iii. Check the fuel supply system.

iv.Check whether the air vent on the fuel tank is unblocked. If there is dirt, it should be removed. Whether the added diesel meets the required grade, whether the amount of oil is enough, and then turn on the oil circuit switch.

v. Loosen the exhaust screw of diesel filter or fuel injection pump, pump oil by hand, and remove the air in the oil route.

vi.Check whether the oil pipe joints are leaking. If there is any problem, it should be handled in time.

II. Water cooling system inspection.

i. Check the water tank, such as insufficient water, should add enough clean soft water or antifreeze.

ii.Check whether the water pipe joints are leaking. If there is any problem, it should be handled in time.

iii. Check whether the tightness of the belt is appropriate. The method is to press the middle of the belt by hand and the belt.

III. Lubrication system inspection.

i. Check whether oil leakage occurs in all oil pipe joints. If there is any problem, it should be handled in time.

ii.Check the amount of oil in the oil pan, draw out the oil ruler of the full loss system, and observe whether the height of the oil meets the requirements of the regulations, if not, it should be adjusted.

IV. Check the circuit system.

i. check the density of battery electrolyte, its normal value is 1.24-1.28, when the density is less than 1.189, indicating that the battery is insufficient, the battery should be charged.

ii. Check whether the circuit is connected correctly.

iii. Check whether there is dirt and oxidation on the battery binding post, if there is, it should be cleaned.

iv. Check whether the starting motor, electromagnetic operating mechanism and other electrical contact is good.

V. Inspection of alternator.

i. Special attention should be paid to the mechanical coupling of single bearing generator, and the breath between rotors should be uniform.

ii. According to the schematic diagram and wiring diagram, choose the appropriate power cable, with copper connector to wiring, copper connector and busbar, busbar fixed tight, the gap of the connector is greater than 0.05mm. If the distance between conductors is greater than 10mm, ground cables need to be installed.

iii. The wiring terminals of the generator outlet box are marked with U, V, W and N, which do not represent the actual phase sequence, which depends on the steering of the generator. UVW refers to the phase sequence of clockwise rotation, and VUW refers to the actual phase sequence of counterclockwise rotation.

iv. Check whether the wiring of the control panel is off, and if necessary, check one by one.
