Abstract
A kind of water diversion apparatus of centrifugal water pump, water diversion tank is the container of a sealing, water diversion tank is connected with aqueduct, drinking-water pipe, connecting water pipe, the connecting water pipe the other end is connected with centrifugal water pump, diversion switch is housed on aqueduct, outlet pipe is housed on centrifugal water pump, and motor is connected with centrifugal water pump by coupling shaft, and the position of drinking-water pipe and water diversion tank joint and the position of outlet pipe upper end are all higher than centrifugal water pump.
Description
Technical field
The utility model relates to
oneplant the water diversion apparatus of centrifugal water pump.
Background technique
Centrifugal pump is utilize vane rotary and make the centrifugal force of water generates carry out work.Centrifugal pump, before startup, must make to be full of water in pump case and suction sleeve, and then starting electrical machinery, makes pump shaft impeller and water do high speed rotary motion, and water, under the effect of centrifugal force, is thrown toward impeller outer edge, flows into the pressure supply water pipe of water pump through the runner of pump case.Water pump vane center, because water forms vacuum after being thrown out of under the effect of centrifugal force, the water in pond is just pressed in pump case under the effect of atmospheric pressure, and impeller is by gyrating, make water under the effect of impeller, constantly flow into and flow out, reached the object of carrying water.Therefore, known centrifugal water pump is each all must carry out water seal to adding water in water pump before using, if do not carry out water seal, water pump vane and pressure supply water pipe have air, air pressure is identical with barometric pressure, starting electrical machinery, and vane rotary can not be discharged air, in the pump housing, can not form vacuum thereby can not produce pressure difference with the external world, still not take out water.
Summary of the invention
Before overcoming the each use of existing centrifugal water pump, all must add the problem of water, the utility model provides a kind of water diversion apparatus of centrifugal water pump, use this device, as long as while using for the first time, to water diversion apparatus topped up with water, water diversion apparatus can keep water pump seal state always, just uses afterwards pump priming again, and water pump can use with the opening.
In order to achieve the above object, to solve the technological scheme that its technical problem adopts be following design to the utility model:
Water diversion tank is the container of a sealing, water diversion tank is connected with aqueduct, drinking-water pipe, connecting water pipe, the connecting water pipe the other end is connected with centrifugal water pump, diversion switch is housed on aqueduct, outlet pipe is housed on centrifugal water pump, motor is connected with centrifugal water pump by coupling shaft, and the position of drinking-water pipe and water diversion tank joint and the position of outlet pipe upper end are all higher than centrifugal water pump.
While using for the first time, open diversion switch, by aqueduct, to water diversion tank, pour water, pour water while reaching the position of drinking-water pipe and water diversion tank joint to the water surface, stop pouring water, close diversion switch, diversion switch tightness will be got well.Because drinking-water pipe and the position of water diversion tank joint and the position of outlet pipe are all higher than centrifugal water pump, so be full of water in centrifugal water pump, reach water seal state.Outlet pipe is connected with smelting furnace cooling water inlet pipe, and the lower end of drinking-water pipe is stretched in pond.Actuating motor, motor drives centrifugal water pump to rotate through coupling shaft, what while just starting, centrifugal water pump was taken out is the water of water diversion tank the inside, because of diversion switch tightness good, so after water diversion tank the inside water reduces, air pressure can decrease, the water in pond is just pressed in water diversion tank under the effect of atmospheric pressure, supplements the water in water diversion tank, constantly circulation said process, completes the whole pump process of centrifugal water pump.After having worked, close motor, centrifugal water pump still keeps water seal because storing water in water diversion tank.While reusing, actuating motor can carry out cyclic process, normally works
Effect of the present utility model is: as long as to water diversion apparatus topped up with water once, use all afterwards pump priming again, deducted the job step of pump priming, saved the time; This apparatus structure is simple in addition, easy to use.

Embodiment
Water diversion tank 1 is the container of a sealing, water diversion tank 1 is connected with aqueduct 3, drinking-water pipe 4, connecting water pipe 5, connecting water pipe 5 the other ends are connected with centrifugal water pump 6, diversion switch 3 is housed on aqueduct 2, outlet pipe 9 is housed on centrifugal water pump 6, motor 8 is connected with centrifugal water pump 6 by coupling shaft 7, and drinking-water pipe 4 and the position of water diversion tank 1 joint and the position of outlet pipe 9 upper ends are all higher than centrifugal water pump 6.
While using for the first time, open diversion switch 3, by aqueduct 2, to water diversion tank 1, pour water, pour water while reaching the position of drinking-water pipe 4 and water diversion tank 1 joint to the water surface, stop pouring water, close diversion switch 3, diversion switch 3 tightness will be got well.Because the position of drinking-water pipe 4 and water diversion tank 1 joint and outlet pipe 9 are all higher than centrifugal water pump 6, so be full of water in centrifugal water pump 6, reach water seal state.Outlet pipe 9 is connected with smelting furnace cooling water inlet pipe, and the lower end of drinking-water pipe 4 is stretched in pond.Actuating motor 8, motor 8 drives centrifugal water pump 6 to rotate through coupling shaft 7, what while just starting, centrifugal water pump 6 was taken out is the water of water diversion tank 1 the inside, because of diversion switch 3 tightness good, so, air pressure rear in water diversion tank 1 the inside water minimizing can decrease, the water in pond is just pressed in water diversion tank 1 under the effect of atmospheric pressure, supplements the water in water diversion tank 1, constantly circulation said process, completes the whole pump process of centrifugal water pump 6.After having worked, close motor 8, centrifugal water pump 6 still keeps water seal because storing water in water diversion tank 1.While reusing, actuating motor 8 can carry out cyclic process, normally works.
