A number of liquid distribution pipes 304 are connected to the end of each main inlet pipe 303. The outlet of the liquid distribution pipe 304 is connected to the inlet of the lubrication part of the fuel injection pump. The present utility model can introduce lubricating oil into the fuel injection pump through the lubrication mechanism 300 by means of the oil pump 200, realizing efficient lubrication operations for multiple fuel injection pumps or multiple lubrication parts of a single fuel injection pump at the same time, with more convenient operation, and solving the problems of poor lubrication effect and low lubrication efficiency in the traditional oil lubrication assembly for fuel injection pumps during the lubrication process, which can only perform lubrication operations on a single fuel injection pump.

[0022] According to an embodiment of the present utility model, as Figures 1-3 shown, the main inlet pipe 303 is fixedly arranged inside the chassis 100 through a support 305. The present utility model can realize the firm support and fixation operation of the main inlet pipe 303 through the support 305, greatly increasing the stability performance of the main inlet pipe 303.

[0023] According to another embodiment of the present utility model, as Figure 1 and Figure 3 shown, a pressure regulating valve 306 is provided on each main inlet pipe 303. The present utility model can conveniently and quickly adjust the pressure of the oil flowing through the main inlet pipe 303 by adjusting the pressure regulating valve 306 on the main inlet pipe 303, so as to prevent the pressure in the lubrication system from being too high, resulting in damage to the pipeline or the fuel injection pump, with safer operation and protecting the system components in the lubrication mechanism 300 from being damaged.

[0024] According to another embodiment of the present utility model, as Figure 1 andFigure 2 As shown, quick-change connectors 307 are provided at the ends of each liquid distribution pipe 304. The brand of the quick-change connector 307 is: XINHUAAO, and the model is: GAOYA.

[0027] Usage method of the utility model:

[0028] First of all, it should be clear that the lubrication component involved in the utility model is mainly used for the efficient lubrication operation of the parts to be lubricated of the fuel injection pump during the performance test of the fuel injection pump. Taking the installation of the lubrication mechanism 300 during the performance test of the fuel injection pump as an example, the usage method is elaborated in detail. When lubricating multiple fuel injectors, first, the operator quickly connects the interface of the liquid distribution pipe 304 to the inlet of the part to be lubricated of the fuel injector to be detected through the quick-change connector 307. Here, a high-pressure rubber connecting pipe with fittings adapted to the quick-change connector 307 at both ends is used for connection. Then, the operator adjusts the opening degree of the pressure regulating valve 306 to an appropriate value (the pressure here corresponds to the pressure resistance performance index of the fuel injector to be detected). Then, the operator starts the engine oil pump 200. The oil pump 200 will pump the engine oil in the fuel tank into the main inlet pipe 303. Finally, it flows through the liquid distribution pipe 304 via the main inlet pipe 303 and enters the part to be lubricated of the fuel injection pump for efficient lubrication operation. The utility model can introduce the lubricating oil into the fuel injection pump through the oil pump 200 via the lubrication mechanism 300, realizing the efficient lubrication operation of multiple fuel injection pumps simultaneously or multiple parts to be lubricated of a single fuel injection pump, making the operation more convenient and solving the problems of poor lubrication effect and low lubrication efficiency in the traditional fuel injection pump engine oil lubrication component during the lubrication process, which can only perform lubrication operations on a single fuel injection pump.

[0029] In addition, it should be noted that in the description of the present utility model, unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0030] The above is the preferred embodiment of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
