How to Correctly Adjust the Output Power of Diesel Generator Sets

Diesel generator sets are not necessarily constant power when in operation. Some special circumstances will cause diesel generators to overrun. When diesel generators are overloaded, or when the power of the generating units purchased by customers is not good, It is necessary to think about the shadow noise brought about by the overloading operation of diesel generator sets.  The output power of a diesel generator set is generally 0.9 times the rated power. The standby power refers to the power that the unit can reach but cannot use for a long time. When the diesel generator set  is overloaded, the power it needs to provide is greater than 0.9 times the rated power. The unit will stop supplying power in order to maintain itself, and the damage to the generator set will not be great. Therefore, be careful to stop the power supply when the generator set is overloaded. Please decelerate the load in time. If you continue to operate this way, the generator set ...

Maintain and Repair Diesel Generator Oil Pump

The oil delivery pump of diesel generator set is single acting piston type. It is mounted o n the side of the fuel injection pump of the diesel generator set and is driven by an eccentric wheel on the injection pump shaft. Its function is to inhale fuel from the tank and supply enough fuel to the diesel generator injection pump with a certain pressure. Before starting the diesel generator set, pump the oil with the hand pump on the oil pump and remove the air from the oil circuit. It can smoothly absorb the fuel within 1 m below the center of the pump in 0.5min. The handle nut must be fastened after the pump oil. The 4 and 6 cylinder B series and B series enhanced fuel injection pumps use roller pumps, as shown in figure 2a. The 12-cylinder B series fuel injection pump is equipped with two rolling wheels, the oil pump on the left and right sides of the inlet and outlet oil pipe joint and a hand pump mounted separately on the front end of the diesel engine block, as shown in f...

How to Adjust the Oil Supply of Diesel Generator Set

If the fuel supply of each cylinder of the diesel generator set is not uniform, for example, sometimes the fuel supply of the cylinder is too large. Sometimes the fuel supply of the cylinder is too small, which will directly affect the stability of the engine, and the removable fuel injection pump can be checked and adjusted on the test bench. However, if a test rig is not available and an uneven fuel supply check is necessary, a rough inspection of the fuel supply of the suspected cylinder can also be carried out. Below introduces the method of checking and adjusting the oil supply of diesel generator set. 1. Prepare two glass gauges for use. If you can't find the metering cylinder for a while, you can also use the same bottle instead. 2. Remove high-pressure tubing connections connected to injectors with a cylinder of too large or too small a fuel supply. 3. Remove the high-pressure pipe connector connected to the injector with a cylinder of normal fuel s...
