Abstract
The utility model provides a device used for replacing a self-priming pump to work, and belongs to the field of water suction pump equipment. The device is used for replacing the self-priming pump to work. The device comprises a centrifugal water mixing pump, a water ring vacuum pump, a centrifugal water mixing pump outlet butterfly valve and a water ring vacuum pump inlet stop valve, wherein the centrifugal water mixing pump outlet butterfly valve is connected with an outlet of a centrifugal water mixing pump drainage check valve, a pipeline on one side of the centrifugal water mixing pump below the centrifugal water mixing pump drainage check valve is connected with an inlet of the water ring vacuum pump, and a water ring vacuum pump inlet stop valve is installed in the pipeline. When the device is used, firstly the centrifugal water mixing pump is drained through the water ring vacuum pump, and then a vacuum mixing pump is started to work. The device can effectively avoid water injection operation in starting of the self-priming pump, resolves the problems that the self-priming pump is difficult to star up, slow in water outflow, and frequent in pump lifting, has small equipment size and small power, saves equipment manufacturing cost and maintenance cost, reduces power consumption to the greatest degree, and saves operating cost.

Background technique
Self-priming pump has heatproof, the several functions such as withstand voltage, wear-resisting, is widely used in the industries such as electronics, electric power, chemical industry, metallurgy, medicine, food, plating, environmental protection, fire-fighting, municipal administration, water purification, defence and military, textile printing and dyeing, digging ore dressing.In a lot of enterprises, usually with self-priming pump as equipment circulating water power source.
Self-priming pump is because the design problem of himself has following shortcoming: 1, self-priming pump work gas-liquid separation process, do not accomplish that start is water outlet.Gas-liquid separation chamber has return port to reflux all the time, and efficient is low; When 2, carrying sewage, easily stop up the forfeiture self-absorption function; 3, self-priming pumps into pipe place switching valve bad sealing, and is fragile, makes the self-priming pump can not self-priming; After the startup, because self-priming time is long, therefore can not reach very soon normal working; 4, first exhaust, rear water outlet, before gas did not have emptying, medium can not inhale, because the suction journey is low, caused the interior water level of pump chamber too high, and leak at the shaft seal place; 5, complex structure, dirt is easy to clean not, maintenance, maintenance cost height; 6, shut down liquid axially toward external leakage, not too suitable for the occasion of Fraquent start equipment; 7, the power of sub-propeller consumption is too large, pump efficiency is low, and power consumption has far exceeded the centrifugal pump under same flow, the lift, has caused great energy waste.
The model utility content
Technical problem to be solved in the utility model provides a kind of device for substituting self-priming pump work, this device can solve self-priming pump and start problem difficult, that water outlet slowly, frequently plays pump, can reduce to greatest extent power consumption simultaneously, save equipment manufacturing cost and maintenance and repair cost.
The technological scheme that solves the problems of the technologies described above is:
A kind of device for substituting self-priming pump work, comprise centrifugal multifunctional pump, Nash hytor, centrifugal multifunctional pump exit butterfly valve, Nash hytor entrance stop valve in its formation, centrifugal multifunctional pump exit butterfly valve goes out the Water Check Valve outlet with centrifugal multifunctional pump and is connected, centrifugal multifunctional pump one side of centrifugal multifunctional pump outlet non-return valve below has pipeline to be connected with the entrance of Nash hytor, and Nash hytor entrance stop valve is installed in pipeline.
Above-mentioned device for substituting self-priming pump work, the water sucking mouth of described centrifugal multifunctional pump and the relief opening of Nash hytor are inserted into respectively in the pulp water pond.
Above-mentioned device for substituting self-priming pump work, described centrifugal multifunctional pump is two, they install respectively centrifugal multifunctional pump exit butterfly valve, pass into the water outlet main pipe after the outlet conduit of two centrifugal multifunctional pump exit butterfly valves is connected, the inlet pipe of Nash hytor is connected by pipeline with two centrifugal multifunctional pumps respectively after by Nash hytor entrance stop valve.
The beneficial effects of the utility model are:
The utility model is at first emptying to centrifugal multifunctional pump by Nash hytor in use, then starts the work of vacuum multifunctional pump.Water filling work when this device can effectively avoid self-priming pump to open has solved self-priming pump and has started problem difficult, that water outlet slowly, frequently plays pump, and complex structure, dirt not easy to clean, the shortcoming such as the maintenance maintenance cost is high, efficient is low, power consumption is high.The utility model selected device small volume, power are less, have saved equipment manufacturing cost and maintenance, repair cost, have reduced to greatest extent power consumption, have saved operating cost, are the best replacement device of self-priming pump.
