Technical background:
At present, the function that the centrifugal pump that China uses in liquid medium is carried has only self-priming, arranges certainly, opens does not certainly have the automatic stop function.Since can not the automatic stop pipeline when not having medium or when breaking down, the impeller idle running of pump can make the component heavy wear of pump, particularly mechanical seal meeting be subjected to badly damaged.The self-priming pump that uses now is that complete machine immerses in the medium in addition, owing to for a long time pump is immersed in the medium, has shortened the working life of pump greatly.
Summary of the invention:
The purpose of this utility model is the deficiency that exists in the above-mentioned technology, provides a kind of centrifugal pump to inhale the start and stop arranging device automatically.Can realize centrifugal pump suction, open, stop, arrange automation.Alleviate working strength of workers simultaneously, reduce user's cost of production.
The purpose of this utility model is achieved in that and comprises centrifugal pump, motor, automatically inhale the start and stop arranging device, pressure switch, drain solenoid valve, it is characterized in that, automatically inhaling the start and stop arranging device links to each other with the centrifugal pump inlet pipe by the liquid level pipeline, and the control circuit of centrifugal pump and the control circuit of inhaling the start and stop arranging device be connected in parallel, centrifugal pump links to each other by coupling with motor, on the export pipeline of centrifugal pump, pressure switch is installed, on the centrifugal pump discharge pipe, connect solenoid valve, automatically barrier film motor and the crank mechanism of inhaling on the start and stop arranging device is fixed on the crankshaft with coupling, plunger is installed on the crank-connecting rod, barrier film links to each other with plunger, the float-ball type liquid-level switch is installed in the liquid level pipeline, driving crank mechanism by coupling rotates, crank mechanism drives plunger and does and pump the liquid level pipeline state that is evacuated, be drawn onto in the liquid level pipeline because of negative pressure up to medium, when medium reaches design height, the float-ball type liquid-level switch is connected centrifugal pump and is started working, and medium transport is arrived the predetermined area.While suction device autostop.When the pressure of output was lower than design pressure, switch automatic disconnection main frame pump was shut down, and the solenoid valve KF that is connected in simultaneously on the centrifugal pump discharge pipe is open-minded, with the mediator depletion that remains in the pump chamber.
Inhale the control circuit of start and stop arranging device and be made up of major loop and control circuit, major loop is connected with control circuit by circuit breaker, and major loop links to each other with the barrier film motor respectively at centrifugal pump motor with thermorelay by the contact of A.C. contactor.
The utility model has the advantages that install on the centrifugal pump and inhale start and stop row machine automatically, product function can replace Under Water Pumps, long shaft submerged pump, makes the centrifugal pump working efficiency be better than self-priming pump, complete machine does not immerse in the medium, and the life-span is better than submerged pump.Automatically draining has realized that centrifugal pump is cold-resistant antifreeze, need not warming; Stop up or autostop when not having medium, increased the Security that centrifugal pump uses, inhale start and stop row machine automatically and can be installed in all centrifugal pump front end inlet places, realize centrifugal pump suction, open, stop, arrange automation.Alleviate working strength of workers simultaneously, reduce user's cost of production.
Description of drawings:

Embodiment:
Below in conjunction with accompanying drawing this enforcement is described further:
As shown in Figure 1, centrifugal pump 3 links to each other by coupling 2 with motor 1, on the export pipeline 4 of centrifugal pump, pressure switch 5 is installed, on the centrifugal pump discharge pipe, connect solenoid valve 14, automatically inhaling the start and stop arranging device links to each other with centrifugal pump inlet pipe 6 by liquid level pipeline 13, barrier film motor 12 links to each other with coupling 11, plunger 9 is installed on the crank-connecting rod 8, barrier film 10 links to each other with plunger 9, float-ball type liquid-level switch 7 is installed in 13 li in liquid level pipeline, the barrier film motor rotates by coupling 11 and drives crank mechanism 8 rotations, crank mechanism 8 drives plungers 9 and does and pump liquid level pipeline 13 state that is evacuated, and is drawn onto in the liquid level pipeline, when medium reaches design height because of negative pressure up to medium, float-ball type liquid-level switch 7 is connected centrifugal pump and is started working, and medium transport is arrived the predetermined area.While suction device autostop.When the pressure of output was lower than design pressure, the pressure switch 5 automatic disconnection main frame pumps of installing on the export pipeline of centrifugal pump were shut down, and the solenoid valve 14 that is connected in simultaneously on the centrifugal pump discharge pipe is open-minded, with the mediator depletion that remains in the pump chamber.
As shown in Figure 2, the control circuit of centrifugal pump is connected in parallel with the control circuit of inhaling the start and stop arranging device, realizes unified control, reaches the work effect that centrifugal pump is inhaled automatically, opens, stops, arranged.When system switches on, the KA1 closure, while KM1 closure, then the barrier film motor rotation begins water filling in the supplying tube of centrifugal pump, in the time of the KA1 closure, the SJ1 closure, the water of centrifugal pump supplying tube is filled with after delaying time, the KJ action.The KM2 closure, the centrifugal pump running.Centrifugal pump running back pressure raises, and KD action KA1, KM1 disconnect, and the barrier film motor shuts down.When system shuts down, the KA2 disconnection of delaying time, takeoff line KF line is connected, in time expand with the water emptying, KA2 disconnections of delay time, discharge solenoid valve is closed, and gets ready for the next one circulates.Its working procedure is as follows:
1, suction automatically: press the SB1 knob, auxiliary reclay KA1, A.C. contactor KM1 adhesive, this machine startup, suction automatically.
2, pump startup operation: after medium is drawn onto the position, near K switch J action, auxiliary reclay KA3 closure, A.C. contactor KM2 adhesive, water pump moves automatically.
3, autostop: pump has automatic shutdown function.When entrance pipe stops up when anhydrous, pressure gauge with electric contact does not have pressure, and contact disconnects, and auxiliary reclay KA1 contact is disconnected, and A.C. contactor KM2 is out of service, the pump autostop.
4, the automatic draining of pump: after pump is shut down, auxiliary reclay KA2 outage, solenoid valve KF opens, and pump discharges water automatically, thereby realizes not needing the manual drainage valve to reach automatic draining, and it is convenient especially to install and use.
Inhale---be the medium in the pipeline to be drawn onto in the liquid level pipeline by the method that plunger type vacuumizes.
Open---be when the liquid in the liquid level pipeline reaches design height, float-ball type liquid-level switch KJ closure, centrifugal pump starts, and inhales the start and stop arranging device and quits work.
Stopping---the pressure that is outlet end when the centrifugal pump entrance pipe stops up or do not have medium descends, and pressure switch KA1 disconnects the centrifugal pump autostop.
Row---be that center-off device KA2 disconnects, the solenoid valve KF that is connected on the centrifugal pump bottom discharge pipeline is open-minded, and medium is discharged in the pump housing automatically.The KF solenoid valve cuts out automatically when the pump startup power supply is connected once more.
