Abstract
The utility model relates to a centrifugal vacuum water diversion device. The utility model comprises a suction pipe which is communicated with an inlet of a water pump and a reservoir, the suction pipe is provided with an air suction pipe which is communicated with an air suction port of a centrifugal vacuum machine and the suction pipe, and the air suction pipe is provided with an electric control valve or a reverse stop valve; the suction pipe is provided with a liquid level controller which is provided with electric contact points. The centrifugal vacuum machine is utilized to pump out the air in the suction pipe so that a medium (the water in the reservoir) can be pumped into the suction pipe; when the medium arises to the center line of an inlet of the water pump, and the electric contact points of the liquid level controller can make the centrifugal vacuum machine cut off and stopped; simultaneously, the electric control valve (or the reverse stop valve) closes the air suction pipe, and the utility model begins to pump the water under the control of the electric contact points of the liquid level controller. The utility model has the advantages that the utility model uses the centrifugal vacuum machine which is used for water diversion; when the utility model is first started, water is not needed to be injected, and gas in the suction pipe can be momentarily exhausted; besides, the utility model has the advantages of quick water pumping, small ground occupation, low investment and convenient maintenance. The utility model is particularly suitable for water pumps which have respectively a large caliber and a large flow rate.
Description
Technical field:
The utility model relates to the water diversion apparatus at a kind of pump entrance place, specifically a kind of centrifugal vacuum water diversion device.
Background technique:
At present, mainly contain backward flow type and suct two kinds of forms of formula in its pump sump modes of place such as industrial and mining enterprise's production, field irrigation, city waters.Backward flow type need be built low level pump house or high water-filled pool.Capital investment is big, long in time limit; And the needs that the formula of sucting has are installed bottom valve or adopt pump intake to add Siphon pot, the employing self-priming pump that has (comprising external mixture type or internal-mixing), displacement pump or vacuum pump suction.More than which kind of the formula of sucting installed all the ubiquity period of exhaust is long, water outlet is slow, bulky problem.Blockage problem easily takes place in the water filling of first start palpus when carrying sewage.In the winter time, the insulation problem of diversion machine, pump and sealing part is difficult to solve.
Summary of the invention:
In view of the deficiency that above-mentioned prior art exists, the purpose of this utility model provides that a kind of floor space is little, little investment, be convenient to keep in repair and period of exhaust is short, water outlet is fast centrifugal vacuum water diversion device.
The purpose of this utility model is achieved by the following technical solution: it comprises the suction pipe that is communicated with pump entrance and wet pit, it is characterized in that: be provided with the sucking pipe that is communicated with centrifugal vacuum machine intakeport and suction pipe on suction pipe, this sucking pipe is provided with motor-operated control valve or check valve; On suction pipe, be provided with the fluid level controller of charged contact.Utilizing centrifugal vacuum machine will suck inner air tube finds time; make medium (water in the wet pit) be drawn into suction pipe; treat that medium reaches the pump entrance center line when above; by the fluid level controller electric contact centrifugal vacuum tester in power-down state is shut down; motor-operated control valve (or check valve) is closed sucking pipe simultaneously; the pump starting begins to draw water under the control of fluid level controller electric contact.
The utility model has the advantages that and adopt centrifugal vacuum power traction stream, first start need not water filling, because centrifugal vacuum machine air displacement is very big, be several times, tens times of several self-sucking device air displacemenies, even it is more, but moment is gone out the gas suction in the suction pipe, forms vacuum (negative pressure), and low level water (water in the wet pit) is introduced in the pump.This device and pump have to inhale emptyly shuts down function, does not have and stops up, need not be incubated, can control automatically, and water outlet is fast and floor space is little, little investment, be convenient to maintenance, to heavy caliber, its advantage of water pump of flow is more remarkable greatly.
Below in conjunction with accompanying drawing the utility model is explained.
Description of drawings:
Accompanying drawing is the utility model structural representation,
Embodiment:
By accompanying drawing as can be known, the utility model mainly is made of suction pipe 1, fluid level controller 5, sucking pipe 8, motor-operated control valve 4 (also can adopt check valve), centrifugal vacuum machine 3.Suction pipe 1 two ends are connected with water and pump entrance pipe 2 in the wet pit 9 respectively, on suction pipe 1, be provided with the sucking pipe 8 that is communicated with centrifugal vacuum machine 3 intakepories and suction pipe 1, this sucking pipe 8 is provided with motor-operated control valve 4, is provided with the fluid level controller 5 of charged contact 5-1,5-2,5-3 on suction pipe 1.When water in the suction pipe 1 reaches the center line G of pumping intake piping 2; electric contact 5-1,5-2 by fluid level controller 5 shut down centrifugal vacuum tester in power-down state; motor-operated control valve 4 is closed sucking pipe 8 simultaneously, and the pump starting begins to draw water under the control of fluid level controller electric contact.Fluid level controller 5, sucking pipe 8, motor-operated control valve 4, centrifugal vacuum machine 3 and suction pipe 1 middle part are installed in the housing 10.Sequence number 6 is the power supply import among the figure, and sequence number 7 is the relief opening of centrifugal vacuum machine 3.
