In two cylinder plunger pumps in above-mentioned jetting machine, described sealing liquid device comprises plunger, plunger bushing, spike and is socketed in spring on the spike, described plunger links to each other with connecting rod, described plunger bushing is embedded on the plunger and described spike is plugged on the plunger bushing, described spring one end is fixed on the spike, and the other end is fixed on the plunger bushing bottom.
In two cylinder plunger pumps in above-mentioned jetting machine, described pump housing top all seals and is fixed with the water shutoff cap.The seepage that can prevent to enter in the pump housing by the water shutoff cap arrives extraneous.
In two cylinder plunger pumps in above-mentioned jetting machine, described pump housing top is equipped with flat valve.Prevent that by flat valve into water flows backwards.
In two cylinder plunger pumps in above-mentioned jetting machine, described intake tunnel and connection position, pump housing bottom are equipped with the spike inserts, and above-mentioned spike end is resisted against on the spike inserts.Can guarantee the sealing when spike is blocked intake tunnel and is communicated with pump housing bottom under the effect of plunger like this.
In two cylinder plunger pumps in above-mentioned jetting machine, be sealed and installed with main water seal between described plunger and the pump housing lower inner wall.The seepage that can prevent to enter in the pump housing by main water seal arrives extraneous.
Compared with prior art, plunger pump in this jetting machine adopts two cylinder plunger pumps, realize suction, setting-out by two cylinder structures, thereby the washing machine spray gun is supplied water, so not only reduce the volume of complete machine, alleviated complete machine weight, lowered noise, but also reduced mechanical loss, improved the efficient of complete machine.
