Abstract
The invention discloses a priming device for a centrifugal water pump. The device is that a water outlet pipe is mounted on the centrifugal water pump; a motor is connected with the centrifugal water pump through a connecting shaft. The device is characterized in that a closed container is used as a priming container and is connected with a priming pipe, a pumping pipe and a connecting water pipe; the other end of the connecting water pipe is connected with the centrifugal water pump; a priming switch is mounted on the priming pipe; the part through which the pumping pipe is connected with the priming container and the upper end of the water outlet pipe are both higher than the centrifugal water pump.
Description
Technical field
The present invention relates to a kind of centrifugal water pump water diversion apparatus.
Background technique
Water pump utilizes vane rotary and the centrifugal force that water is produced carrys out work.Before activation, must make to be full of water in pump case and suction sleeve, then starting electrical machinery, make pump shaft impeller and water do high speed rotary motion, water under the influence of centrifugal force, is thrown toward impeller outer edge to water pump, and the runner through pump case flows into the pressure supply water pipe of water pump.Water pump vane center, because water is thrown out of rear formation vacuum under the influence 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 constantly flow under the effect of impeller and flow out, reach the object of conveying water.Therefore, all must to water pump in add water before known centrifugal water pump uses at every turn and carry out water seal, 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 discharge air, vacuum can not be formed in the pump housing and thus can not produce pressure difference with the external world, still not take out water.
Summary of the invention
All water problem must be added to overcome before existing centrifugal water pump uses at every turn, the invention provides a kind of water diversion apparatus of centrifugal water pump, use this device, as long as first time is when using, to water diversion apparatus topped up with water, water diversion apparatus can keep water pump seal state always, and using afterwards just can pump priming again, and water pump can use with the opening.
In order to achieve the above object, the technical solution adopted for the present invention to solve the technical problems is following design: diversion container is the container of a sealing, diversion container 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 aqueduct is equipped with, centrifugal water pump is equipped with outlet pipe, and motor is connected with centrifugal water pump by coupling shaft, and the position of drinking-water pipe and diversion container joint and the position of outlet pipe upper end are all higher than centrifugal water pump.
First time when using, is opened diversion switch, is poured water by aqueduct to diversion container, and pour water when reaching the position of drinking-water pipe and diversion container joint to the water surface, stop pouring water, cut out diversion switch, diversion switch tightness will be got well.Because drinking-water pipe and the position of diversion container joint and the position of outlet pipe are all higher than centrifugal water pump, so be full of water in centrifugal water pump to reach water seal state.Be connected with smelting furnace cooling water inlet pipe by outlet pipe, the lower end of drinking-water pipe is stretched in pond.Actuating motor, motor drives centrifugal water pump to rotate through coupling shaft, the water of diversion receptacle that what when just starting, centrifugal water pump was taken out is, because diversion switch tightness is good, so after diversion receptacle water reduces, air pressure can decrease, the water in pond is just pressed in diversion container under the effect of atmospheric pressure, supplements the water in diversion container, continuous circulation said process, namely completes the whole pump process of centrifugal water pump.After having worked, close motor, centrifugal water pump is still because diversion stored in containers has water to keep water seal.When reusing, actuating motor can carry out cyclic process, and normal work effect of the present invention is: as long as to water diversion apparatus topped up with water once, and using afterwards all need not pump priming again, has deducted the job step of pump priming, has saved the time; This apparatus structure is simple in addition, easy to use.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is further described.
Fig. 1 is a kind of structural representation of centrifugal water pump water diversion apparatus.
Embodiment
Diversion container 1 is the container of a sealing, diversion container 1 is connected with aqueduct 3, drinking-water pipe 4, connecting water pipe 5, connecting water pipe 5 the other end is connected with centrifugal water pump 6, diversion switch 3 aqueduct 2 is equipped with, outlet pipe 9 centrifugal water pump 6 is equipped with, motor 8 is connected with centrifugal water pump 6 by coupling shaft 7, and the position of drinking-water pipe 4 and diversion container 1 joint and the position of outlet pipe 9 upper end are all higher than centrifugal water pump 6.
First time when using, is opened diversion switch 3, is poured water by aqueduct 2 to diversion container 1, and pour water when reaching the position of drinking-water pipe 4 with diversion container 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 diversion container 1 joint and outlet pipe 9 are all higher than centrifugal water pump 6, so be full of water in centrifugal water pump 6 to reach water seal state.Be connected with smelting furnace cooling water inlet pipe by outlet pipe 9, 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, the water that what when just starting, centrifugal water pump 6 was taken out is inside diversion container 1, because diversion switch 3 tightness is good, so after inside diversion container 1, water reduces, air pressure can decrease, the water in pond is just pressed in diversion container 1 under the effect of atmospheric pressure, supplements the water in diversion container 1, continuous circulation said process, namely 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 diversion container 1.When reusing, actuating motor 8 can carry out cyclic process, normally works.
