Abstract
The invention discloses a kind of water recovery apparatus with centrifugal pump, including centrifugal pump, suction hose and outlet pipe, check-valves is provided with suction hose, branch's return pipe is set between outlet pipe and suction hose, valve is provided with branch's return pipe；So when interval work needs for pump case and suction hose to fill water, can open valve makes the aqueous reflux in outlet pipe be poured in pump case and suction hose, and compared with existing artificial mode, the present invention has easy to operate, manpower is saved, the advantages of high working efficiency.
Description
Technical field
The present invention relates to a kind of water recovery apparatus with centrifugal pump, belong to centrifugation pump technical field.
Background technology
Centrifugal pump is to be rotated using impeller and make water that centrifugal motion occur come work.Water pump is before activation, it is necessary to make pump
Water is full of in shell and suction hose, then starts motor, pump shaft impeller and water is done high speed rotary motion, water occurs centrifugation fortune
It is dynamic, impeller outer edge is thrown toward, flow into the pressure pipe road of water pump through the runner of volute pump case.Therefore centrifugal pump is in interval work,
Often need that pump case and suction hose manually are filled into water, it is low that this kind of mode has operating efficiency, it has not been convenient to etc. defect.
The content of the invention
The technical problem to be solved in the present invention is：A kind of water recovery apparatus with centrifugal pump is provided, with simple structure,
It is easy to operate, save manpower the advantages of, to overcome the deficiencies in the prior art.
The technical scheme is that：A kind of water recovery apparatus with centrifugal pump, including centrifugal pump, suction hose and water outlet
Pipe, is provided with check-valves on suction hose, branch's return pipe is set between outlet pipe and suction hose, in branch's return pipe
On be provided with valve.
Flowmeter is installed on the suction hose or outlet pipe, the FPDP of the flowmeter is connected with PLC,
PLC is connected with the control port of centrifugal pump and valve again.
The beneficial effects of the invention are as follows：The present invention is branched back to by setting one between the suction hose and outlet pipe of centrifugal pump
Water pipe, so when interval work needs for pump case and suction hose to fill water, can open valve fills the aqueous reflux in outlet pipe
In pump case and suction hose, compared with existing artificial mode, the present invention has easy to operate, saving manpower, work effect to note
The advantages of rate is high.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
In accompanying drawing：1st, centrifugal pump, 2, suction hose, 3, outlet pipe, 4, check-valves, 5, valve, 6, flowmeter, 7, branch's return pipe.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment to invention be described further：
With reference to Fig. 1, a kind of water recovery apparatus with centrifugal pump of the invention, including centrifugal pump, suction hose 2 and outlet pipe 3, inhaling
Check-valves 4 is provided with water pipe 2, branch's return pipe 7 is set between outlet pipe 3 and suction hose 2, in branch's return pipe 7
On be provided with valve 5.
As the further of the present embodiment, flowmeter 6 is installed on the suction hose 2 or outlet pipe 3, the flowmeter 6
FPDP be connected with PLC, PLC is connected with the control port of valve 5, PLC again and centrifugal pump
Connection, such PLC obtains its real-time running parameter from centrifugal pump, and PLC obtains flow monitoring from flowmeter 6
Data, now when centrifugal pump also operationally, and the flow number transmitted at flowmeter 6 is when being less than preset value, PLC control
Valve processed 5 is opened, and the water in outlet pipe 3 is back to pump case and suction hose 2, and after it is filled, centrifugal pump can normal pumping.
The preferred electrically operated valve of valve 5 in the present invention..
Above content is to combine specific preferred embodiment further description made for the present invention, it is impossible to assert
Specific implementation of the invention is confined to these explanations.For general technical staff of the technical field of the invention,
On the premise of not departing from present inventive concept, some simple deduction or replace can also be made, should be all considered as belonging to of the invention
Protection domain.
