Description
Technical field
The utility model belongs to centrifugal water pump technical field, more particularly to a kind of water supply system.
Background technology
Now widely used centrifugal water pump, during startup optimization, it is necessary to assure water is full of in centrifugal pump spiral casing, just can be with
Start normal operation.In order to prevent the water after water pump stops in spiral case from flowing away, the method that check-valves is added frequently with water inlet pipe bottom,
Avoid starting all to the operation of water filling in water pump spiral casing every time.In practical application, there are problems that using check-valves：1. winter
When temperature is relatively low, due to also there being water in outlet pipe, after water pump is out of service, the long period is shut down（One evening）, outlet pipe
Interior icing, gently then causes line clogging, heavy then cause frost crack pipe.2. mining main drainpipe road is thicker, draining vertical height compared with
Height, in water pump non-normal stop, the huge kickback pressure of backwater frequently results in the rupture of pump outlet check-valves, makes check-valves
Failure.
Utility model content
In order to solve above-mentioned deficiency of the prior art, check-valves is fragile and pipeline easily icing during solving use
Technical problem, the utility model provides a kind of water supply system.
The utility model is achieved by the following technical programs.
A kind of water supply system, it includes centrifugal pump and seal box, it is characterised in that：Seal box will absorb water in The Small Well
Liquid the water inlet of centrifugal pump is pumped to by suction hose, the water outlet of centrifugal pump is provided with check-valves, the seal box
On vacuum meter is installed, seal box top is provided with inlet and water injection valve, and seal box sidewall bottom is provided with liquid outlet, sealing
Bottom face is provided with sewage draining exit, and the inlet is connected by suction hose with water suction The Small Well, and it is small that the suction hose extends to water suction
Bottom, water suction pipe end is provided with filter screen.
Further, the filter screen material is stainless steel.
Further, it is provided with blowoff valve on the sewage draining exit.
Further, bottom surface of the liquid level less than seal box in the water suction The Small Well.
Further, the dischargeable capacity of the seal box is not less than 1.5 times of suction hose total measurement (volume), and the seal box has
Effect volume is along the volume to inlet on liquid outlet.
Further, the through hole of a diameter of 10mm is provided with the check-valves valve block.
Further, the distance between the liquid outlet and seal box bottom surface are 5 ~ 10mm.
The utility model has the advantages that compared with prior art.
The utility model avoid using check-valves produce it is fragile the problems such as, effectively prevent pipeline ice formation issues,
Operating personnel can substantially judge the height of water level according to the reading of vacuum table, prevent water sucking mouth from surfacing.Meanwhile, if hair
Too low, the failure that the Pump Suction mouth of a river is surfaced in unboiled water position, vacuum table does not have negative pressure, and operating personnel can at once judge the original that is out of order
Cause, is easy to fix a breakdown rapidly.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
In figure, 1 is water suction The Small Well, and 2 is suction hose, and 21 is filter screen, and 3 is seal box, and 31 is inlet, and 32 is liquid outlet,
33 is water injection valve, and 35 is sewage draining exit, and 351 is blowoff valve, and 4 is centrifugal pump, and 41 is water inlet, and 42 is check-valves.
Specific embodiment
The utility model is elaborated with reference to embodiment, the present embodiment is with technical solutions of the utility model
Premised under implemented, give detailed implementation method and specific operating process, but protection domain of the present utility model
It is not limited to following embodiments.
As shown in figure 1, a kind of water supply system, it includes centrifugal pump 4 and seal box 3, it is characterised in that：Seal box
3 water inlets 41 that the liquid absorbed water in The Small Well 1 is pumped to centrifugal pump 4 by suction hose 2, the water outlet of centrifugal pump 4 is set
There is check-valves 42, vacuum meter 34 is installed on the seal box 3, the top of seal box 3 is provided with inlet 31 and water injection valve 33, close
The sidewall bottom of joint sealing 3 is provided with liquid outlet 32, and the bottom surface of seal box 3 is provided with sewage draining exit 35, and the inlet 31 passes through suction hose 2
Connected with water suction The Small Well 1, the suction hose 2 extends to water suction The Small Well 1 bottom, and the end of suction hose 2 is provided with filter screen 21, the filter
The material of net 21 is stainless steel, reduces corrosion impact and maintenance workload.
Further, it is provided with blowoff valve 351 on the sewage draining exit 35.
Further, bottom surface of the liquid level less than seal box 3 in the water suction The Small Well 1.
Further, the dischargeable capacity of the seal box 3 is not less than 1.5 times of the total measurement (volume) of suction hose 2, the seal box 3
Dischargeable capacity on liquid outlet 32 along the volume to inlet 31.Vacuum water tank designed size is moderate, should not too greatly or too
