Abstract
The invention relates to an automatic water diversion device which belongs to an auxiliary facility of a water pump. The automatic water diversion device comprises a water inlet pipe (1) of a centrifugal water pump, a water storage tank (2) and a water storage tank water diversion pipe (3), wherein the water inlet pipe (1) of the centrifugal water pump is communicated with the bottom side of the water storage tank (2); the water storage tank water diversion pipe (3) is communicated with the higher end of the water storage tank (2); the top of the water storage tank (2) is communicated with a water injection pipe (4); and the water injection pipe is provided with a control valve (5). The invention solves the problem that water injection is needed before the centrifugal water pump is started, and can fully inject the water storage tank when the centrifugal water pump is used for the first time, thereby enhancing the vacuum degree of a working system and increasing the water diversion height of the water diversion pipe.
Description
Technical field
The invention belongs to the supporting facility of water pump, be specifically related to a kind of automatic water diversion device.
Background technique
Water pump is filled water in advance, when starting mode of pump, the water of pump case is thrown in the impeller rotation out, enter out pipeline and deliver to eminence, and produce certain flow velocity and lift, the water in the water pump aqueduct just in time adds in the pump case, at this moment, vacuum will appear in the aqueduct, i.e. negative pressure state, and just the pressure in the aqueduct is lower than barometric pressure.Therefore, water in the lake in the pond, in the river, in the water channel is just fortunately under the atmospheric effect, in water pump penstock flow water inlet pump case center, and the pressure in this moment water pump pump case is lower, water in the water pump aqueduct will flow in the pump case continuously, under the impeller action of centrifugal force, to discharge pump case continuously and go out pipeline and deliver to eminence, water pump will normally draw water continuously, send water.So when the water pump design and installation, want automatic diversion, generally always water pump be installed in below the water surface.But in the river, in the lake, in the water channel, the words of drawing water in the puddle.Water pump is installed in more than the water surface., install like this, must the feed water pump pump case before starting mode of pump and suction line fill water, could start water pump, and pump water inlet must have the check bottom valve could guarantee to pour water successfully.When often occurring bottom valve in the practice and be not closed completely, the quite difficulty of pouring water, the time is long, and it is many to leak, and uses very inconvenient.
In order to address the above problem: on June 17th, 1992 Chinese utility model patent notification number CN 2107550U to disclose a kind of " water storage box type self-priming pump " be to add a water storage box with common centrifugal water pump.It neither influences the efficient of centrifugal water pump, flow and lift, and can reach turn on pump again is water outlet, but water storage box lacks inlet control device, pours water and will pour into from pump case when using for the first time, and it is discontented to cause water storage box to pour water, degree of vacuum is not high during work, thereby has significantly reduced the diversion height of aqueduct.
Summary of the invention
Technical problem to be solved by this invention is, overcome the deficiencies in the prior art, a kind of automatic water diversion device is proposed, not only solved and to have needed the problem of pouring water before centrifugal pump starts, but also can be when using for the first time, water storage box is filled, improved the degree of vacuum of system works, thereby can improve the diversion height of aqueduct.
The technological scheme that technical solution problem of the present invention is taked is: a kind of automatic water diversion device comprises the intake pipe of centrifugal water pump, water storage box and water storage box aqueduct; The bottom side of the logical water storage box of the intake pipe of centrifugal water pump, the water storage box aqueduct is communicated with the high-end of water storage box; Be connected with an irrigation pipe at the water storage box top, control valve is housed on the irrigation pipe.
Principle of the present invention is: water storage box and water pump are to be communicated with by intake pipe, water pump is filled water in advance by water storage box, when starting mode of pump, the water of pump case is thrown in the impeller rotation out, water in the water storage box just in time adds in the pump case, at this moment, vacuum will occur in the water storage box, be negative pressure state, just the pressure in the water storage box is lower than barometric pressure.Therefore, water in the lake in the pond, in the river, in the water channel is just under atmospheric effect, flow in the water storage box by the water storage box aqueduct, and the pressure in this moment water pump pump case is lower, water in the water storage box will flow in the pump case continuously, under the impeller action of centrifugal force, discharge pump case continuously, water pump will normally draw water continuously, send water.
The present invention adopts automatic water diversion device to replace the original program of pouring water, and has avoided heavy manual labor, guarantees that water pump can timely, normally start, and is convenient to realize automation.
Description of drawings
Fig. 1 is a structural front view of the present invention;
In the accompanying drawing: the intake pipe of 1 centrifugal water pump; 2 water storage boxs; 3 water storage box aqueducts; 4 irrigation pipes; 5 control valves.
Embodiment
Below in conjunction with embodiment shown in the drawings, the present invention is described in further detail:
As shown in Figure 1: a kind of automatic water diversion device comprises the intake pipe 1 of centrifugal water pump, water storage box 2 and water storage box aqueduct 3; The bottom side of the intake pipe 1 logical water storage box 2 of centrifugal water pump, water storage box aqueduct 3 is communicated with the high-end of water storage box 2; It is characterized in that: be connected with an irrigation pipe 4 at water storage box 2 tops, control valve 5 is housed on the irrigation pipe.
