Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As shown in Figure 1-2, a kind of high pressure reciprocating pump crankshaft cavity water-inlet-proof structure, including the pump with connecting rod chamber and crankshaft cavity
Body, the connecting rod chamber rear portion are provided with mounting hole, and connecting rod chamber front portion via through holes are connected with crankshaft cavity, in the mounting hole
Packing seal set is provided with, the anterior external diameter of packing seal set is less than the external diameter at rear portion, and the front portion of packing seal set is arranged at peace
Fill in hole, the rear portion of packing seal set is located at outside the pump housing, and plunger, extension bar are disposed with the packing seal set, described
Extension bar front end is stretched into connecting rod chamber by packing seal set front portion, and extension bar front end and the rear end of the connecting rod in connecting rod chamber are first
