Problems solved by technology

[0004] In view of the related technologies mentioned above, the inventor believes that when the plunger pump works normally, the plunger and the cylinder body rub against each other to generate heat, and at the same time, the water flows from the The water inlet flows in and flows out from the water outlet, taking away part of the heat in time and assisting the heat dissipation of the plunger pump; but when pumping water from rivers and canals, the filter prevents debris from entering the water pipe and plunger pump with the water flow. At this time, the debris It is easy to block the filter, causing the plunger pump to run idly, and the heat dissipation of the plunger pump is not good, which affects the service life of the plunger pump

Embodiment Construction

[0048] The following is attached Figure 1-3 The application is described in further detail.

[0049] refer tofigure 1 , when the plunger pump is used to take water from rivers and canals, the water inlet 31 of the plunger pump is connected to a water pipe 1, the other end of the water pipe 1 is connected to a filter 2, and the filter 2 is placed 666 in the river and canal .

[0050] The filter 2 is cylindrical as a whole, and its side wall is provided with filter holes at intervals. The filter holes are used for water supply to pass through and block water plants and other sundries. When the filter holes block the sundries, the sundries may block the filter 2 .

[0051] The embodiment of the present application discloses a plunger pump. When the filter 2 is blocked by sundries, the filter 2 is unblocked so that the plunger pump can work normally.

[0052] refer to figure 2 , The plunger pump includes a pump body 3 , a water reservoir 4 and a commutator 5 .

[0053] The p...

Abstract

The invention relates to a plunger pump. The plunger pump comprises a pump body, a water storage device and a reverser, wherein the reverser has two states, in a normal working state, a water pipe communicates with a water inlet of the pump body, an inlet of the water storage device communicates with a water outlet of the pump body so as to take water from a riverway and a canal through the waterpipe, and a certain amount of water is stored in the water storage device; and in the dredging working state, the inlet of the water storage device communicates with the water inlet of the pump body,the water pipe communicates with the water outlet of the pump body, and after the water temporarily stored in the water storage device is pressurized by the pump body, the water flushes a filter so asto dredge the filter.

Description

technical field [0001] The present application relates to the field of hydraulic pumps, in particular to a plunger pump. Background technique [0002] The horizontal plunger pump is installed side by side with several plungers (generally 3 or 6), and a crankshaft is used to push the plunger to reciprocate in the cylinder through the connecting rod mechanism, so that the volume of the sealed working cavity is generated. Changes, and then realize the hydraulic pump that can absorb and discharge liquid. [0003] In agricultural irrigation and spraying, water is usually taken from rivers and canals, refer to figure 1 Farmers connect one end of the water pipe to the water inlet of the plunger pump, place the other end of the water pipe in the river or canal, and use the gasoline engine, diesel engine and other prime movers to drive the plunger pump, so that the plunger pump can be used to draw water from the river and canal , complete irrigation and spraying. At the same time,...
