Description
Technical field
It the utility model is related to centrifugal pump water injection technology field, more particularly to a kind of centrifugal pump of horizontal axis automatic water filling device.
Background technology
With economic continuous development, centrifugal pump of horizontal axis is by its is simple in structure, shockproof, low noise, dimension is fixedly mounted
Application of the advantages that shield is convenient, energy-efficient in production engineering is also more and more extensive, but when using centrifugal pump of horizontal axis, by
In environment temperature change dramatically, operating mode frequently change or adjust and the pump housing reach service life or Operation and Maintenance it is improper cause it is dynamic
Ring friction is secondary and the failure of stationary ring friction secondary seal ring, damage, result in centrifugal pump of horizontal axis leak, discharge reduction in the pump housing, can not
It is normal to start, thus be required to manually fill water from centrifugal pump of horizontal axis water outlet pipe part during each use, it could normally start centrifugation
Pump, greatly increases the workload of staff.
Utility model content
The technical problems to be solved in the utility model is：
A kind of centrifugal pump of horizontal axis automatic water filling device is provided, can not normally start and need to solve centrifugal pump of horizontal axis leak
The problem of artificial recharge.
The technical solution of the utility model is：
A kind of centrifugal pump of horizontal axis automatic water filling device, including centrifugal pump of horizontal axis, water tank, cistern, the water tank
Above centrifugal pump of horizontal axis, water storage pot bottom is provided with water tank outlet pipe, water tank outlet pipe is unidirectional by first
Valve is connected with horizontal centrifugal water pump outlet pipe；Water tank upper side is provided with water tank water inlet pipe, water tank water inlet pipe is with storing
Pond connects.
Water filling port is provided with the top of the water tank.
The second check valve is provided with the water filling port.
End cap is provided with the water filling port.
The beneficial effects of the utility model：
The utility model above centrifugal pump of horizontal axis by installing a water tank, and the water in water tank is due to gravity
To inject in centrifugal pump of horizontal axis, pressure in water tank reduces and is less than external atmosphere pressure, according to principle of negative pressure, the water in cistern
Water tank is injected under external atmosphere pressure effect, stops water filling when the air pressure in water tank is consistent with ambient pressure, constantly
Above step is repeated, solves the problems, such as that centrifugal pump of horizontal axis leak can not normally start and need artificial recharge, alleviates work
The working strength of personnel, while the utility model has the advantages of simple structure and easy realization automated control, without other energy consumptions, saves the energy,
It is with good economic efficiency.

Embodiment
As shown in Figure 1, a kind of centrifugal pump of horizontal axis automatic water filling device, including centrifugal pump of horizontal axis 1, water tank 6, cistern
10, the water tank 6 is installed on the top of centrifugal pump of horizontal axis 1, and the water in water tank 6 is injected horizontal centrifugal by gravity
In pump 1, water tank outlet pipe 5 is provided with 6 bottom of water tank, water tank outlet pipe 5 passes through the first check valve 4 and horizontal centrifugal
Water pump outlet pipe 3 connects, therefore the water in water tank 6 can only flow to centrifugal pump of horizontal axis 1, it is impossible to reverse flow；On 6 top of water tank
Side is provided with water tank water inlet pipe 9, and water tank water inlet pipe 9 is connected with cistern 10, by principle of negative pressure by pond 10
In water extruding injection water tank 6.
The top of water tank 6 is provided with water filling port 7, for 6 first water filling of water tank and exhaust.
The second check valve 8 is provided with the water filling port 7, after the water of certain volume is filled in water tank 6, is closed
Second check valve 8, prevents outside air from entering in tank body.
End cap is provided with the water filling port 7, after the water of certain volume is filled in water tank 6, end cap is closed, prevents
Only outside air is entered in tank body.
The utility model concrete operation method is as follows：
Step 1：The check valve a4 on water tank outlet pipe 5 is closed, opens the check valve b8 or end cap at the top of water tank 6,
Enough water is injected in from 6 crest water flooding mouth 7 of water tank toward tank body, the air with water injection rate same volume is exhausted, is then shut off
Second check valve 8 or end cap at the top of water tank 6；
Step 2：When 1 good seal of centrifugal pump of horizontal axis, when drainage does not occur, automatic water filling device does not open at this time
It is dynamic；When centrifugal pump of horizontal axis 1 is there are during drainage, discharge reduction in the pump housing, then need to open first on water tank outlet pipe 5
Check valve 4, the water in water tank 6 is due in gravity injection centrifugal pump of horizontal axis 1, supplementing the water being lost in the pump housing, at this time
Centrifugal pump of horizontal axis 1 possesses entry condition；
Step 3：After water in water tank 6 is injected into centrifugal pump of horizontal axis 1, the pressure in water tank 6 reduces and less than the external world
Atmospheric pressure, according to principle of negative pressure, the water in pond 10 injects water tank 6 under external atmosphere pressure effect, until in water tank 6
Air pressure stops water filling when consistent with ambient pressure, continuous repeat step 2 and step 3 are so as to fulfill 1 automatic water filling of centrifugal pump of horizontal axis.
