Reasons for Why My Diesel Generator Set Fail to Start

During the process of using diesel generators, many customers will find that they often encounter situations where diesel generators cannot be started, which will greatly affect the efficiency of diesel generators. Engineer from Jiangsu Starlight Electricity Equipment Co.,Ltd help everyone analyze the reason and solutions of why diesel generator can not start. I Fuel system malfunction, the diesel engine is driven by the starting motor and does not ignite. 1.   There's air in the fuel system. Check if the fuel line connection is loose and remove air from the fuel system. First unscrew the exhaust screws on the injection pump and the fuel filter and pump the oil with the hand pump until there are no bubbles in the spilled fuel. After, tighten the exhaust screw. Pump oil again, when there is return oil in the tubing, then tighten the hand pump. Loosen the nut of the high pressure tubing at one end of the injector, pry high injection pump plunger spring ...

Electromagnetic Start Switch for Generating Set

There are two kinds of control switches in the electric start system of generator set: electromagnetic type and mechanical type. The electromagnetic switch is driven by the electromagnetic force to pull the fork to start. When starting the diesel engine, press the switch. At this time, the circuit is as follows: the battery switch, the connecting post 5, the iron absorption coil, the connecting post, the generator and the iron battery. The current flowing through the iron suction coil makes the core magnetized to produce suction force, and the moving contact is sucked down and closed with the static contact. At this time, the circuit flowing through the starting switch is as follows: the battery terminal 4 moves the contact point and the static contact keeps the coil; the attracting coil is connected with the pole 3 and the starting line of the starter  is equipped with an iron storage battery. At this point, the current flows through the DC motor, but because ...

Diesel Generator Fuel and Engine Oil Mix Up Problem

Treatment of Cummins Generator set after mixing fuel and Oil The fuel and oil of the Cummins generator set have completely different functions. They can not be mixed. Once the fuel and oil are mixed, there is a problem with the seal of the generator set, which happens from time to time in use. Below is the Cummins generator set fuel and oil after the treatment of mixed. 1. Pump membrane rot or degumming, so that diesel oil into the oil tank and oil mixing. When the oil pump is removed and the pressure is added to the oil inlet and outlet pipes on the oil pump test bench, if no leakage of diesel oil is found, the pump is in good condition. 2. The injector has low opening pressure and poor atomization, which causes diesel oil to flow into the oil pan and oil along the cylinder wall. Remove the injector and test it on a high-pressure oil pump test rig. If the injector fuel injection pressure meets the requirements, atomization is good, indicating that the injector is in go...
