Hands-on teaching you the correct disassembly and installation of diesel generator set electronically controlled monoblock pump (a)

Diesel generator injection pump injection advance angle is the crankshaft rotation angle relative to the crankshaft stop at the moment diesel fuel starts to be injected into the cylinder, which is one of the important factors affecting the working condition of diesel generators. The monoblock pump is the device used to generate the injection pressure of the injector, and the correct installation or not of the injection pump on the diesel generator will directly affect the accuracy of the injection advance angle.

Diesel Generator

 

Diesel generator injection pump injection advance angle is the crankshaft angle at the moment when diesel fuel starts to be injected into the cylinder relative to the crankshaft stop, it is one of the important factors affecting the working condition of diesel generators, the monoblock pump is the device used to generate the injection pressure of the injector, and the correct installation of the injection pump on the diesel generator will directly affect the accuracy of the injection advance angle, in order to let you better understand this principle, this article Top Bo power will teach you hands-on correct disassembly and installation of diesel generator set electronically controlled monoblock pump.

 

A, the monoblock pump disassembly steps

 

1, clean the monoblock pump room around the dirt.

 

2, turn the diesel generator to a cylinder compression upper stop position.

 

3, remove the camshaft position sensor and gasket, placed together in the clean area.

 

4, remove the gear chamber cover, and then remove the signal disc and timing gear (disassemble the gear mark, to facilitate the next assembly).

 

5、Remove the high pressure oil pipe and each low pressure oil pipe.

 

6、Loosen the connecting plate bolt and support plate bolt, and take off the monoblock pump chamber.

 

7, disassemble the monoblock pump, loosen the monoblock pump two locking bolts (first ring to loosen all, slightly loose a few degrees angle, gently shake the monoblock pump by hand, let it loose under the action of spring force out. (If you can't do it by hand, you can use wood to knock lightly, but never knock the plug parts). After the monoblock pump leaves the sealing part, then loosen all the bolts and take off the monoblock pump, and make a good mark.

 

Note: Because the monoblock pump spring force is very large, when disassembling must be gradually loosened, otherwise, light damage to the monoblock pump, serious injury.

 

8、Take off the tappet positioning bolt and remove the tappet.

 

9、Loosen the connecting plate bolt and take off the camshaft.

 

10、Clean the parts, especially the oil channels in the pump room.
