[0002] Since most plunger pumps use metal plungers, when the plunger pump is working, the reciprocating movement of the plunger will generate heat by friction. To solve the problem of cooling and lubrication of the plunger, in the initial stage, water was used for lubricating and cooling the plunger on the plunger pump test bench, but the lubricating and cooling effect was not very ideal. Later, after changing the medium for lubricating and cooling the plunger to emulsion, the lubricating and cooling effect was significantly improved. However, after changing the medium to emulsion, a separate liquid tank is required to place the emulsion medium, and issues such as how to cool the emulsion tank and how to supply the emulsion to the plunger pump need to be considered. Therefore, it is necessary to design a special liquid tank for placing the emulsion, as well as a system for supplying the emulsion and a cooling system. Content of the Utility Model
