Precautions for VE Distribution Pump of Diesel Generator

Due to its complex structure and shape, as well as a variety of models and specifications, the VE distribution pump for diesel generators is a precision accessory. Therefore, in order to avoid quality problems during use, the following points should be noted:

1. The VE distribution pump model that matches the diesel generator should be selected correctly. If the selection and matching are incorrect, the VE distribution pump will not be able to be used or meet the usage requirements.

2. The plunger spring and its guide rod used in conjunction with the VE distribution pump should be correctly selected, and all components such as adjusting washers, upper and lower seats, upper and lower gaskets, pre travel gaskets, support springs, and oil outlet valve gaskets should be adjusted. If the selection is incorrect, the oil pump will not be able to be successfully debugged.

3. During the transportation, storage, and disassembly process of VE distribution pumps, they should be handled with care and should not be bumped, rusted, magnetized, parts scattered, and cleanliness exceeding standards.

4. When disassembling the VE distribution pump, it is necessary to clean all surfaces of the parts with light diesel to avoid scratching the surface of the parts with iron filings, impurities, etc. Especially for the outer surface of the two-stage working plunger, it is strictly prohibited to collide or scratch the working surface and sharp edges of the holes in the matching and control sleeves, to ensure the high-precision geometric shape and good sliding performance of each matching surface.

5. When assembling the oil pump assembly, the drive shaft, coupling, camshaft, roller seat, oil pump and other components that are matched with the VE distribution pump should be assembled correctly in sequence, and qualified products should be selected to avoid damage to the VE distribution pump due to quality problems or incorrect assembly of the above components during oil pump operation.

6. When debugging the oil pump assembly for oil quantity and uniformity, it is first necessary to ensure the correctness of the KF and K values of the VE distribution pump. Then, quality inspection should be carried out on the oil output coupling parts, standard injectors, solenoid valves, high-pressure oil pipes, etc., and cleaned thoroughly. Otherwise, it will directly affect the smooth debugging of the oil quantity and its uniformity, and also affect the authenticity of the relevant parameters and characteristics of the VE distribution pump under working conditions, Causing incorrect analysis and judgment of the quality of the VE distribution pump itself.

7. Use labeled, high-quality, clean diesel fuel. During use, the VE distribution pump should be kept away from the magnetic field to avoid magnetization, which may cause iron filings to adhere to the parts, resulting in jamming and fracture, and unnecessary quality accidents.

Special reminder from Dingbo Electric Power: If the VE distribution pump of a diesel generator encounters collision, J damage, rust, deformation during transportation, storage, and disassembly, or if the cleanliness of the components exceeds the standard or the oil quality is not clean due to other reasons, and the iron filings, impurities, etc. adhere to the working surface of the parts, causing poor sliding or even jamming of the parts, the cause should be analyzed and forced assembly is strictly prohibited. Otherwise, the VE distribution pump will be stuck or broken, Even the serious consequences of damaging the assembly.

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
