Abstract

The utility model relates to a water pump for the irrigation of agriculture, particularly a water pump with a large caliber which is used for water absorption and pumping-out of energy resources by making use of natural water power resources when electric force energy resources are insufficient. The end corresponding to the water inlet of a pump body is provided with a flow spill valve. The top of the pump body is connected with an air compressor. The top of the pump body and the bottom of the air compression are is provided with a water feeding valve, and the top of the water feeding valve is provided with a through hole which is connected with a water pumping-out pipe. Thus, the utility model can not only save energy resources, but can achieve continuously automatic water-supply. The utility model has the advantages of simple structure, low cost, easy maintenance and servicing.

Description

Large calibre fluid force moment water pump

The utility model relates to a kind of agricultural irrigation water pump, and particularly electric power energy is not enough and utilize natural waterpower resourses to make the heavy caliber water pump that draws water, pumps up water of the energy.

At present, the water pump that pumps up water that common agricultural irrigation is used is to adopt electric energy, wind energy, solar energy or manpower as power, and near the water source, rural area China outlying mountain area, hilly country and reservoir is then comparatively general, is not but utilized fully.

In view of this, the purpose of this utility model provides a kind of heavy caliber fluid moment water pump, is used as power with the water-head of open water supply (water reservoir, pond, river, lake etc.), reaches automatically by the current moment of inertia to draw water, pump up water.

The purpose of this utility model is achieved in that at the relative end of pump housing water inlet and is provided with a relief valve, connect an air compressor on pump housing top, be provided with a water supply valve on pump housing top and place, air compressor bottom, and the water supply valve top is provided with through hole connection lifting pipe.

Owing to adopt such scheme, can energy saving, and can obtain continuous automatic water-supply again, and device structure is simple, and maintenance is easily, and is cheap.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a fundamental diagram of the present utility model.

Fig. 2 is an embodiment's of the utility model a structural representation.

Among the figure: 1. tank, 2. aqueduct, the 3. pump housing, 3a. separates impact end, 4. relief valve, 5. water supply valve, 6. air compressor, 6a. fluviograph, 7. lifting pipe.

In the embodiment shown in Figure 2:

The water inlet place of the pump housing 3 is communicated with aqueduct 2, a relative end is to separate impact end 3a, at the water outlet place that separates impact end 3a a relief valve 4 is installed, hydraulic pressure hour relief valve 4 in the pump housing 3 is opening state, hydraulic pressure increases to one regularly, relief valve 4 cuts out, and depends on the spring force in the relief valve 4.

The bottom end opening of air compressor 6 is communicated with the pump housing 3 open-toppeds, and air compressor 6 open-toppeds are communicated with lifting pipe 7, also be communicated with a fluviograph 6a in air compressor 6 sides, showing and to adjust the proper proportion of air supply and water level, to reach the best effect of pumping up water.

Water supply valve 5 is installed the pump housing 3 open-toppeds and air compressor 6 bottom end opening places, hydraulic pressure hour in the pump housing 3, and water supply valve 5 is closed condition, and hydraulic pressure is increased to one regularly, and water supply valve 5 is opened automatically, depends on the spring force that water supply valve 5 is interior.

Water pump of the present utility model pump up water process and working principle thereof:

As depicted in figs. 1 and 2, aqueduct 2 is that the cast iron tube of bore more than 250 millimeters imbedded underground, wherein an end puts in tank 1(river, the lake, reservoir, pond etc.) in the downside, the water that makes tank 1 is under the pressure of water-head, automatically flow in the aqueduct 2, enter the pump housing 3, flow to and separate impact end 3a, flow out through spilling water valve 4, make aqueduct 2 interior current quicken to enter in the pump housing 3, the pump housing 3 interior hydraulic pressure are increased spilling water valve 4 cuts out, at this moment, water supply valve 5 is backed down, water flows in the air compressor 6, makes to fill compressed-air actuated air compressor 6 internal pressures increase; When hydraulic pressure in the pump housing 3 descends, water supply valve 5 is closed automatically, simultaneously, spilling water valve 4 is opened automatically, and current quicken in the aqueduct 2, the pump housing 3 interior hydraulic pressure increase thereby make again, return multiple circulation with this, air compressor 6 internal pressures are constantly increased, therefore, the water of raising out through lifting pipe 7 is higher than tens meters of tank 1 waters surface, and (3～6 cun of lifting pipe 7 water outlet apertures) are for field irrigation and life in the countryside water etc.

In addition, water pump of the present utility model not only utilizes the natural water source water-head to realize the large size automatic water-supply, and keeps continuous water supply, also is superior to natural energy resources such as solar energy, wind energy.Simple (not having complicated rotating machinery) maintenance of its device structure and maintenance are all easy, and the limit that is particularly suitable for abundant water does not have area and hilly country.
