Abstract
The utility model provides a water lifting system which is convenient to use and low in failure rate. The water lifting system comprises circulating water pumps and is characterized in that the number of the circulating water pumps is larger than one and an overall filter screen is arranged outside the plurality of the circulating water pumps. A vacuum pump and a vacuum buffer pipe are further arranged outside the circulating water pumps, wherein the vacuum pump is connected with a pipe channel of the vacuum buffer pipe. The vacuum buffer pipe is connected with the circulating water pumps through the pipe channel and the vacuum pump is connected with the overall filter screen through the pipe channel. The water lifting pump has the advantages of facilitating working procedures when the circulating water pumps are started, reducing the repair problems in an operating process, and improving the working efficiency.
Description
Technical field
The utility model relates to sewage renovation technique field, relates in particular to a kind of water pumping system.
Background technique
In sewage treatment deodorizing improvement project, quoted the lithotroph filtrate, have the good treatment effect for the high complex waste gas of intractability.
Deodoration system mainly is made up of following equipment, glass fibre reinforced plastics filter tank, socket, filtrate, filter tank damping device, circulating water pump 3, blower fan, irrigation system, instrument and valve, electric control cubicle, instrument control system.
In the existing technology, circulating water pump 3 absorbs water from the filter tank, is sent to eminence.Before starting circulating water pump 3, need first water with filling in the pump case 7, behind the starting electrical machinery; As shown in Figure 2; The main shaft of circulating water pump 3 rotates with regard to impeller 8 together, and the blade on the impeller 8 makes the fierce rotation of the water in the pump case 7, under action of centrifugal force; Water is sucked by bottom valve 5 places of circulating water pump 3 in the pump case 7, moves to expulsion valve 10 or funnel 9 along suction pipe 6.Because the discharge of the water in the pump case 7; Impeller 8 inlets have just formed a low pressure area or region of no pressure in the pump case 7, have produced certain pressure difference in filter tank liquid level and the pump case 7, and the water in the filter tank is under the promotion of this pressure difference; Suction inlet filter screen 4 and bottom valve 5 through circulating water pump 3 lower ends get in the circulating water pump 3 along suction pipe 6; Impeller 8 constantly rotates in the pump case 7, and under action of centrifugal force, water is sent to eminence continuously by the filter tank.
But because the sewage impurity in the filter tank is more, be prone to cause the suction inlet filter screen 4 of circulating water pump 3 lower ends to stop up, water can not suck in the pump case 7 along suction pipe 6, causes circulating water pump 3 idle running, and then causes machine to seal problems such as serious wear, has increased the maintenance rate of circulating water pump 3.
The model utility content
The problem that the utility model will solve provides a kind of easy to use, water pumping system that rate of fault is low.
The technological scheme of the utility model is following: a kind of water pumping system, comprise circulating water pump, and it is characterized in that: more than one of said circulating water pump; Be connected with total filter screen outside said some circulating water pump; Also be provided with vacuum pump and vacuum buffer pipe outside the said circulating water pump, said vacuum pump is connected with the vacuum buffer pipeline; Said vacuum buffer pipe is connected through pipeline with circulating water pump; Pipeline is connected between said vacuum pump and the total filter screen.
Further, be provided with first vacuum valve between said vacuum pump and the total filter screen.
Further again, also be provided with second vacuum valve between said vacuum pump and the total filter screen.
Further, be provided with the first vacuum buffer valve between said vacuum pump and the vacuum buffer pipe.
Further, be provided with the second vacuum buffer valve between said vacuum buffer pipe and the circulating water pump.
Further, be equipped with first circulating valve and second circulating valve on said any circulating water pump.
The beneficial effect of the utility model is: through a kind of water pumping system of the utility model, the operation when having made things convenient for circulating water pump to start has also reduced the operating problem of reprocessing, and has improved working efficiency.
