How to Replace Diesel Unit Pump and Maintenance Tips

The function of the diesel unit pump is to generate the injection pressure for the injector. For engines using a single-pump electronic fuel injection system, there are multiple unit pumps corresponding to the number of cylinders. According to the different high-pressure generating devices, fuel injection systems can be divided into distributor pumps, in-line pumps, fuel injectors, and single-pump electronic fuel injection systems. The unit pump fuel supply system is an advanced technology for diesel engines, which can not only improve the power and economic indicators of diesel engines but also meet higher emission standards.

Machines, like humans, can often "get sick". If a machine is not installed and used correctly or not properly maintained, some parts may be damaged, leading to the entire machine not operating normally. Therefore, Dingbo Diesel Generator Manufacturer introduces to you today how to correctly replace the diesel unit pump and related maintenance skills.

Maintenance Tips for Diesel Unit Pump

1.Composition of the unit pump fuel system: Fuel comes out of the fuel tank 1, enters the diesel pump 3, then passes through the diesel filter 5 for filtration, and enters the low-pressure fuel chamber cast in the box.

2.Maintenance of the low-pressure oil circuit: It is necessary to regularly check whether the low-pressure oil circuit pressure, fuel transfer pump flow, oil return check valve and other related components are normal. In addition, the diesel engine governor also needs to be repaired and maintained regularly.

Precautions for Unit Pump Replacement

1.When replacing the unit pump, it cannot be simply replaced with a new one; the thickness of the unit pump gasket needs to be calculated for replacement.

2.Unit pumps of the same diesel engine cannot be used interchangeably. When it is necessary to disassemble the unit pump for inspection, special marks must be made to ensure that the unit pump and gasket of each cylinder correspond one-to-one. The unit pump cannot be assembled randomly during assembly, which is very important for the proper maintenance of the diesel generator set.
