Abstract
The invention relates to a vacuum emptying device for a water pump and belongs to the technical field of water pump emptying equipment. The vacuum emptying device for the water pump is constituted by a water ring type connecting pipe, a water outlet pipe and a main emptying pipe. The bottom of a water storage bucket is connected with a water ring vacuum pump through the connecting pipe. The outlet end of the water ring vacuum pump communicates with the top of the water storage bucket through the water outlet pipe. The inlet end of the water ring vacuum pump is connected with the main emptying pipe. The main emptying pipe is provided with an isolating valve. Multiple emptying branch pipes are arranged at one side of the isolating valve at intervals. The emptying device is simple in structure, convenient to use and capable of thoroughly removing air in a water inlet pipe of the water pump, and thus the problem of 'idling' or 'cavitation erosion' caused by residual air in the water inlet pipe in the operation process of the water pump is avoided; and the production application requirement of an enterprise is met.
Description
Technical field
The present invention relates to a kind of pump vacuum emptier, belong to emptying water pump equipment technical field.
Background technology
Water supply well is called for short pipe well, and pipe well is to be vertically mounted on underground water intake or the tubulose structures of protection subsoil water.Pipe
Well is the extraction work being completed subsoil water by water pump in the course of the work.In actual use, long when pipe well water-pump
Not used time time, the remaining substantial amounts of air of meeting in the water inlet pipe of pipe well water-pump, so that water pump produces " idle running " or " cavitation erosion "
Problem, and then substantially reduce the service life of water pump.It is therefore desirable to a kind of emptier of research and development so that it is water pump can be entered
Air in water pipe drains, and to avoid water pump " to dally " or the generation of " cavitation erosion " problem, thus extends the service life of water pump.
Summary of the invention
It is an object of the invention to: a kind of simple in construction, easy to use is provided, remain because of water inlet pipe solving existing water pump
The pump vacuum emptier of " idle running " or " cavitation erosion " problem that air causes.
The technical scheme is that
A kind of pump vacuum emptier, it is made up of water-ring vacuum pump, water butt, connecting tube, outlet pipe and emptying house steward；
It is characterized in that: the bottom of water butt is connected by connecting tube water-ring vacuum pump, and the port of export of water-ring vacuum pump passes through
Outlet pipe connects with the top of water butt；The entrance point of water-ring vacuum pump connects emptying house steward；It is provided with on emptying house steward
Isolating valve, interval, isolating valve side shape is provided with multiple emptying arm.
It is provided with vacuum table on described emptying house steward.
The side of described water butt is provided with blow-off pipe.
It is provided with switch valve in described connecting tube.
In described water butt, activity is equipped with multistorey strainer mesh.
It is an advantage of the current invention that:
This kind of pump vacuum emptier, simple in construction, easy to use, emptying arm is connected with the water inlet pipe of each water pump, when
During water-ring vacuum pump work, the air in water inlet pipe can be got rid of clean.Thus when avoiding water pump operation, because of water inlet pipe
The generation of " idle running " or " cavitation erosion " problem that interior residual air causes, extends the service life of water pump, meets enterprise and produces
The needs used.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1, water-ring vacuum pump, 2, water butt, 3, connecting tube, 4, outlet pipe, 5, emptying house steward, 6, filter screen, 7, row
Empty arm, 8, vacuum table, 9, blow-off pipe, 10, switch valve, 11, isolating valve.
Detailed description of the invention
This pump vacuum emptier is by water-ring vacuum pump 1, water butt 2, connecting tube 3, outlet pipe 4 and emptying house steward 5
Constitute；The bottom of water butt 2 is connected by connecting tube 3 water-ring vacuum pump 1.Switch valve 10 it is provided with in connecting tube 3.Water storage
The setting height(from bottom) of bucket 2 is higher than the setting height(from bottom) of water-ring vacuum pump 1, and the purpose being arranged such is: so that water butt 2
In water deadweight effect under, be flowed in water-ring vacuum pump 1, and then avoid water-ring vacuum pump 1 " idle running " problem
Generation.
The port of export of water-ring vacuum pump 1 is connected with the top of water butt 2 by outlet pipe 4；Entering of water-ring vacuum pump 1
Mouth end connects emptying house steward 5；Being provided with isolating valve 11 on emptying house steward 5, interval, isolating valve 11 side shape is provided with multiple row
Empty arm 7, one end of emptying arm 7 connects with pump water inlet.The purpose being provided with isolating valve 11 on emptying house steward 5 exists
In: when this emptier is on the shelf, by isolating valve 11, emptying house steward 5 can be completely enclosed, and then prevent the sky in the external world
Gas is entered in pump water inlet by water-ring vacuum pump 1, emptying house steward 5 and emptying arm 7.
Being provided with vacuum table 8 on emptying house steward 5, the purpose arranging vacuum table 8 is: personnel convenient to operate judge that emptying is total
Negative pressure condition in pipe 5, when its negative pressure reaches certain negative pressure value, illustrates that the air in pump water inlet empties, subsequently
People could start water pump.
The side of water butt 2 is provided with blow-off pipe 9.The purpose arranging blow-off pipe 9 is: so that by water butt 2
Precipitate is discharged.In water butt 2, activity is equipped with multistorey strainer mesh 6.The purpose arranging filter screen 6 is: will enter the water in water butt 2
Filter, prevent impurities in water from too much blocking connecting tube 3.
First need during the work of this pump vacuum emptier to open switch valve 10 and isolating valve 11.Now in water butt 2
Water can flow in water-ring vacuum pump 1 by connecting tube 3, then starts water-ring vacuum pump 1.When water-ring vacuum pump 1 works,
By emptying arm 7 and emptying house steward 5, the air in pump water inlet can be emptied, make pump water inlet presents negative pressure shape
State.Under negative pressure state, the water in pipe well can be adsorbed come up and be full of by pump water inlet by pump water inlet.Then start water
Pump, can avoid water pump " to dally " or the generation of " cavitation erosion " problem.After water pump runs well, close isolating valve 11, water successively
Ring vacuum pumps 1 and switch valve 10.
In water-ring vacuum pump 1 work process, under the effect of negative pressure, when water-ring vacuum pump 1 can be total by emptying
Water in pipe well is adsorbed by pipe 5 and emptying arm 7, and is inputted in water butt 2 by water by outlet pipe 4, thus reach to
The purpose of water butt 2 moisturizing.
This kind of pump vacuum emptier, simple in construction, easy to use, it is possible to the air in pump water inlet to be got rid of dry
Only.Thus when avoiding water pump operation, because of the generation of " idle running " or " cavitation erosion " problem that residual air in water inlet pipe causes, extend
In the service life of water pump, meet the needs of enterprise's production and application.
