Description
Technical field
The utility model relates to a kind of water plug, particularly a kind of centrifugal pump water plug that adopts vacuum water tank.
Background technique
Existing centrifugal pump water plug mainly contains two kinds of structures, and a kind of is the centrifugal pump water plug that adopts the assembling bottom valve, and bottom valve is one-way valve, is arranged on the intake pipe of centrifugal pump; Another kind is the centrifugal pump water plug that adopts diversion voluntarily, and the height on its intake pipe and centrifugal pump pump top is all in the pumping plant below the water inlet pool water surface, and owing to there being height difference, water can be introduced in centrifugal pump voluntarily.
But there is following shortcoming in above-mentioned two kinds of structures: its bottom valve loss of head of water plug of assembling bottom valve structure is larger, has reduced the efficiency of drawing water of centrifugal pump, and bottom valve easily stops up or is not closed completely besides, causes the difficulty of drawing water; The water plug of drawing water structure does not take full advantage of the pumpage of centrifugal pump voluntarily, and the centrifugal pump Installation Elevation is lower simultaneously, has not only increased basic excavated volume, and operation management is also inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of centrifugal pump water plug that adopts vacuum water tank is provided.It is simple in structure, and cost is low, and stable and reliable operation.
The technical solution of the utility model is: a kind of centrifugal pump water plug that adopts vacuum water tank comprises centrifugal pump, drives motor, the vacuum water tank of centrifugal pump.
Described vacuum water tank is closed box, and the top of vacuum water tank is respectively equipped with water injecting pipe and outlet pipe, and water injecting pipe is provided with Water filling valve, and outlet pipe is provided with drain tap.Side at the vacuum water tank top is provided with the vacuum water tank intake pipe.Side in the vacuum water tank bottom is respectively equipped with drain pipe and outlet pipe, and the mounting point of outlet pipe, higher than the mounting point of drain pipe, is provided with sewage draining valve on drain pipe, is provided with flowing water Valve on outlet pipe.
Centrifugal pump and motor are arranged on base, and the output shaft on motor is connected with the input shaft of centrifugal pump by coupling, by the driven by motor centrifugal pump, are worked.The shaft axis of centrifugal pump is higher than the bottom surface of vacuum water tank, and the water intake of centrifugal pump is connected with the outlet pipe on vacuum water tank, and the water outlet of centrifugal pump is connected with conduit pipe, and conduit pipe is provided with water-delivery valve, and the height of conduit pipe is higher than the height of vacuum water tank.
The volume of vacuum water tank to little be three times of intake pipe volume, the twice that the height of vacuum water tank is the water tank diameter, the mounting point of the vacuum water tank close centrifugal pump of should trying one's best.
Using method of the present utility model and working principle are as follows: the intake pipe on vacuum water tank stretches in pond, before centrifugal pump starts, close sewage draining valve and flowing water Valve, open drain tap, by water injecting pipe, vacuum water tank is filled with to water, air in vacuum water tank is discharged by outlet pipe, then opens flowing water Valve, closes drain tap.Restart centrifugal pump and draw water, centrifugal pump is by outlet pipe and from vacuum water tank water inlet, the conduit pipe water delivery from centrifugal pump, the water delivery process causes the water level in vacuum water tank to descend, mineralization pressure is poor, and the water in pond is inhaled into vacuum water tank under atmospheric effect, completes whole pump process.
The utility model compared with prior art, has following advantage:
1, substitute traditional bottom valve with vacuum water tank, improved the efficiency of centrifugal pump pump water, hydraulic loss is little, with respect to the water plug that assembles the bottom valve structure, can save energy 10%-15%.
2, substitute and adopt the pumping plant of the water plug of drawing water structure voluntarily with vacuum water tank, reduced basic excavated volume, reduced installation difficulty, be conducive to realize the automation control of centrifugal pump group.
Below in conjunction with the drawings and specific embodiments, detailed construction of the present utility model is further described.
The accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
