Description
Technical field
The utility model relates to a kind of centrifugal pump, especially a kind of vacuum water diversion centrifugal pump device.
Background technique
Centrifugal pump all needs artificial pump priming before starting pump at every turn, and the artificial pump priming time is longer.One-way bottom valve is poorly sealed, causes pump inlet pipeline not liquid storage, and causes pump priming liquid to run off cannot be full of the pump housing from pump inlet pipeline when pump priming.Due to the leakage of inlet line bottom valve, fill with liquid deficiency when pump priming in the double-suction centrifugal pump pump housing, operative employee lacks experience, and make centrifugal pump be in " false exhaust " state running for a long time, cause liquid gasification in the pump housing, impeller dallies.At the exhaust initial stage, centrifugal pump vibrations are comparatively large, cause centrifugal pump entirety vibrations wearing and tearing for a long time; In centrifugal pump pump, water-filling is not enough, and the mechanical seal dry grinding time is longer, serious wear, and wastage exceeds standard, and pollutes pump surrounding environment; Mechanical seal is too short for working life, and the frequency of maintenance of centrifugal pump increases, and drops into the problems such as the expense of keeping in repair also strengthens.
Summary of the invention
The purpose of this utility model overcomes the deficiencies in the prior art, provides a kind of and can improve the vacuum water diversion centrifugal pump device opening pump efficiency.
The utility model vacuum water diversion centrifugal pump device is achieved through the following technical solutions: vacuum water diversion centrifugal pump device is made up of vacuum pump, centrifugal pump, float valve, electric valve, threeway outlet pipe and intake pipe.
Described outlet of centrifugal pump one end and the connection of vacuum pump are connected and fixed by threeway outlet pipe; Centrifugal pump inlet one end is connected to intake pipe.
Described threeway outlet pipe is made up of straight tube and standpipe, and standpipe is fixed on the centre of straight tube, and the inside of straight tube and standpipe is through, sealing; Threeway outlet pipe has three mouths.1, a mouth of straight tube is connected to centrifugal pump, and another mouth is water outlet, and the water outlet of straight tube is provided with electric valve.2, one end of standpipe is fixed on the centre of straight tube, and standpipe presses close to the position of straight tube, is provided with float valve; The other end of standpipe is connected to vacuum pump.
Described electric valve is electric ball valve, or Electric Actuated Stop Valves, or electric vacuum valve; It is the valve that sealing is high that electric valve requires, can not have gas leak phenomenon.
Described float valve is stainless steel floating ball valve, or plastic floating ball valve.Float valve controls the water level of vertical liquid in pipe, and the water level of liquid reaches design attitude, with regard to throttle down, so just stops the overflow of liquid.
Described liquid is water, or oil, or the raw material of industry of liquid.
The utility model compared with prior art has following beneficial effect: vacuum water diversion centrifugal pump device ensure that when starting centrifugal pump, have the function of exhaust diversion, and storage is expired and enoughly drawn liquid in centrifugal pump body.Self priming centrifugal pump device both simplified pipe-line system, which in turn improved working condition; Also have compact structure, easy to operate, operate steadily, safeguard easily, the advantage such as efficiency is high, the life-span is long.
Accompanying drawing explanation
Fig. 1 is the utility model vacuum water diversion centrifugal pump device structural representation.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1: vacuum water diversion centrifugal pump device is made up of vacuum pump (2), centrifugal pump (1), float valve (4), electric valve (3), threeway outlet pipe (8) and intake pipe (6) road.
The connection of one end that described centrifugal pump (1) exports and vacuum pump (2) is connected and fixed by threeway outlet pipe (8); One end of centrifugal pump (1) import is connected to intake pipe (6).
Described threeway outlet pipe (8) is made up of straight tube and standpipe, and standpipe is fixed on the centre of straight tube, and the inside of straight tube and standpipe is through, sealing.Threeway outlet pipe (8) has three mouths; 1, a mouth of straight tube is connected to centrifugal pump (1), and another mouth is water outlet (9), and the water outlet (9) of straight tube is provided with electric valve (3).2, one end of standpipe is fixed on the centre of straight tube, and standpipe presses close to the position of straight tube, is provided with float valve (4), and the other end of standpipe is connected to vacuum pump (2).
Described electric valve (3) is electric ball valve.
Described float valve (4) is stainless steel floating ball valve.
Described liquid is oil.
The workflow step during work of vacuum water diversion centrifugal pump device is as follows.
1, before centrifugal pump (1) starts, close electric valve (3), start the gas in vacuum pump (1) suction centrifugal pump (1) pump housing, liquid is along with the gas minimizing in centrifugal pump (1) pump housing, intake pipe (6) is entered by the water intake (5) of intake pipe (6), centrifugal pump (1) pump housing, in threeway outlet pipe (8), when in centrifugal pump (1) pump housing, after being full of liquid in intake pipe (6) and threeway outlet pipe (8), the ball float of float valve (4) is subject to the buoyancy of liquid and closes outlet after rising, vacuum pump (2) stops exhaust work, at this moment centrifugal pump (1) pump housing is interior with regard to filled with liquid, now synchronous averaging centrifugal pump (1) and open electric valve (3), centrifugal pump (1) just starts discharge opeing work.
2, when centrifugal pump (1) quits work, electric valve (3) close synchronously, filled with liquid in centrifugal pump (1) pump housing, the closedown sealing of electric valve (3) ensure that the liquid of centrifugal pump (1) pump housing internal memory relies on atmospheric pressure completely, rest in centrifugal pump (1) pump housing, ensure Absolute truth reciprocal of duty cycle, stop the liquid in centrifugal pump (1) pump housing because pressure change refluence is gone back, ensure like this to run well at the upper centrifugal pump (1) that once starts.
3, when centrifugal pump (1) quits work, centrifugal pump (1) quits work for a long time, liquid in centrifugal pump (1) pump housing may leak, at this time the ball float of float valve (4) is by lowering less than the buoyancy of liquid, and the outlet of float valve (4) reopens.When centrifugal pump (1) starts again next time, close electric valve (3), start the gas in vacuum pump (1) suction centrifugal pump (1) pump housing, after making centrifugal pump (1) possess starting condition, now start centrifugal pump (1) and open electric valve (3), centrifugal pump (1) just starts discharge opeing work.
More than that vacuum water diversion centrifugal pump device provided by the utility model is introduced; apply specific case herein to set forth structural principle of the present utility model and mode of execution; above embodiment just understands making method of the present utility model and core concept thereof for helping; concrete enforcement is not limited to above-mentioned concrete mode of execution; those skilled in the art is from above-mentioned design; without performing creative labour; done many variations, all at protection domain of the present utility model.
