Abstract
The invention discloses a kind of vacuum plant with centrifugal pump, including centrifugal pump, suction hose and outlet pipe, check-valves is provided with suction hose, the exhaust tube being connected with vavuum pump is provided with the suction hose of centrifugal pump and check-valves, valve is provided with exhaust tube；So when interval work needs to extract the air in pump case and suction hose so as to centrifugal pump normal work out, valve vacuum pump work can be opened, compared with existing artificial or vacuumizing mode, the present invention has easy to operate, the advantages of saving manpower, high working efficiency.
Description
Technical field
The present invention relates to a kind of vacuum plant 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 manually pump case and suction hose to be filled into water, or the air in it is released, this kind of mode has operating efficiency lowly,
The defects such as inconvenience.
The content of the invention
The technical problem to be solved in the present invention is：A kind of vacuum plant 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 vacuum plant with centrifugal pump, including centrifugal pump, suction hose and water outlet
Pipe, is provided with check-valves on suction hose, and the pumping being connected with vavuum pump is provided with the suction hose of centrifugal pump and check-valves
Pipe, is provided with valve on exhaust tube.
Flowmeter is installed on the suction hose or outlet pipe, the FPDP of the flowmeter is connected with PLC,
Control port of the PLC again respectively with centrifugal pump, the control port of valve and vavuum pump is connected.
The beneficial effects of the invention are as follows：The present invention sets vavuum pump by between the suction hose and outlet pipe of centrifugal pump,
So when interval work needs to extract the air in pump case and suction hose so as to centrifugal pump normal work out, valve can be opened true
Empty pump work, compared with existing artificial or vacuumizing mode, the present invention has easy to operate, saving manpower, operating efficiency
High the advantages of.
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, flowmeter, 6, valve, 7, exhaust tube, 8, true
Empty pump.
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 vacuum plant 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, the exhaust tube being connected with vavuum pump 8 is provided with the suction hose 2 of centrifugal pump and check-valves 4
7, valve 6 is provided with exhaust tube 7.
As the further of the present embodiment, flowmeter 5 is installed on the suction hose 2 or outlet pipe 3, the flowmeter 5
FPDP be connected with PLC, PLC again respectively with centrifugal pump, the control port of valve 6 and vavuum pump 8
Control port is connected.So PLC obtains its real-time running parameter from centrifugal pump, and PLC is obtained from flowmeter 5
Flow monitoring data, now when centrifugal pump also operationally, and the flow number transmitted at flowmeter 5 is when being less than preset value, PLC
Controller control valve door 6 is opened, and is used vavuum pump 8 and is started working, and the air in pump case and suction hose 2 is extracted out so as to centrifugal pump
During normal work.
The preferred electrically operated valve of valve 6 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.
