Analyze the preparation before starting MTU diesel generator set

Preparation of diesel generator set before starting

1) Clean the dust, water trace, rust and other foreign bodies attached to the diesel generator set, and remove the oil and ash scale in the air filter;

2) A comprehensive inspection of the diesel generator set of the entire device, the connection should be tight, the control mechanism should be flexible, crankshaft rotation should be no stuck phenomenon;

3) Check whether the cooling system is filled with coolant and the pump is filled with suction water. Pipeline leakage or blockage (including air resistance) phenomenon;

4) Check the fuel stock in the fuel tank, open the fuel switch, loosen the bleed bolt of the high pressure oil pump, remove the air in the fuel line, and tighten the bleed bolt;

5) Check whether the oil level is between the two calibration lines of the oil scale, and whether the fuel pump and governor have enough oil;

6) Check the reliability and flexibility of the governor lever and oil pump rack connection, but also check whether there is enough oil;

7) Check whether all electrical circuits (including charging and starting circuits) are connected correctly and in good contact;

8) Check whether the fittings of diesel engine supply, lubrication, cooling and other systems are leaking and leaking;

9) All components in the control panel shall be complete, clean, free from damage and loose;

10) Disconnect the silicon rectifier and capacitor, remove the ground wire, use a 500 volt megohm meter to determine the insulation resistance of the primary line and rotor winding to the ground should not be less than 3 megohm, otherwise drying measures should be taken;

11) Check the generator to switch screen wiring should be correct, negative through the double throw switch access control screen, should be isolated from the grid (air break, should be in a short circuit position; The U, V and W ends of the generator correspond to the bus of the control panel;)

12) Check whether the position of each switch on the control panel is normal, the main switch should be opened, and the control panel with automatic voltage regulation should be placed in the manual position;

13) Instrument (except frequency table) pointer should refer to zero;
