Model utility content
The purpose of this utility model is to provide a kind of vertical water pump anti-freezing structure, and solving existing water pump needs manually drainage exhaust on the spot, the problem that operation is wasted time and energy.
Another object of the present utility model is to improve the cold-resistant antifreeze ability of water pump.
The utility model solves the technological scheme that its technical problem adopts: a kind of vertical water pump anti-freezing structure, comprise water pump body, and on water pump body, be provided with water intake, water outlet, drain opening and relief opening; On the pipeline that described water intake connects, be provided with inlet valve, on the pipeline that water outlet connects, be provided with outlet valve, on the pipeline that drain opening connects, be provided with drain valve, on relief opening, be connected with outlet pipe, on outlet pipe, be provided with outlet valve; Also be provided with PLC control cabinet, the opening and closing of the each valve of PLC control cabinet control.
Further, described PLC control cabinet comprises CPU module, digital quantity input module and digital output module, and digital quantity input module actuation button is connected or is connected with upper-position unit by CPU module; Digital output module is connected with each valve by relay.In described outlet pipe, be also provided with floating-ball level switch, floating-ball level switch is connected with the digital quantity input module of PLC control cabinet by cable.
For improving the cold tolerance of water pump body, the outer surface of described water pump body is also enclosed with one layer of heat preservation cotton.In described heat-preservation cotton, be also provided with heating wire and temperature transducer.
The beneficial effects of the utility model: by the water intake at water pump, water outlet, drain opening and relief opening, valve being set, and by the switching of each valve of PLC control cabinet control, realize water inlet and draining to water pump, easy to operate.And can also pass through PC control PLC control cabinet, realize telecontrol, greatly improve the convenience of water pump control.Make, after water pump is shut down, can automatically get rid of the water in water pump and pipeline, play antifreeze effect.For improving the safeguard function of water pump body, on water pump body, install heat-preservation cotton and heating wire additional, improve the antifreeze ability of water pump.
Below with reference to drawings and Examples, the utility model is described in detail.
Brief description of the drawings
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is the structural representation of the utility model water pump.
Embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of vertical water pump anti-freezing structure, comprises water pump body 1, the outer surface of described water pump body 1 is also enclosed with one layer of heat preservation cotton 10; In heat-preservation cotton 10, be also provided with heating wire and temperature transducer.Described heating wire is connected with temperature controller with temperature transducer, and the temperature that water pump detected when temperature transducer is during lower than setting temperature, and the heating of temperature controller control heating wire has improved the temperature of water pump, prevents that water pump is freezing.
On described water pump body 1, be provided with water intake, water outlet, drain opening and relief opening; On the pipeline that described water intake connects, be provided with inlet valve 2, on the pipeline that water outlet connects, be provided with outlet valve 3, on the pipeline that drain opening connects, be provided with drain valve 4, on relief opening, be connected with outlet pipe 5, on outlet pipe 5, be provided with outlet valve 6, in described outlet pipe 5, be also provided with floating-ball level switch 8; Control for convenience the switching of each valve, be also provided with PLC control cabinet 7 in order to control the opening and closing of each valve.
Described PLC control cabinet 7 comprises CPU module, digital quantity input (DI) module and digital output (DO) module, on PLC control cabinet 7, be provided with turn on pump button and termination of pumping button, turn on pump button is connected with DI module with termination of pumping button, by pressing actuation button, signal is passed to DI module, by the switching of the each valve of DO module controls, DO module is connected with each valve by relay again.
Described DI module can also be connected with upper-position unit cable by CPU module, thereby can carry out telecontrol to water pump by upper-position unit.
In the time that the DI of PLC control cabinet module receives the turn on pump instruction from button or upper-position unit, the DO module controls relay of PLC control cabinet is opened inlet valve and drain valve, the impurity in washery pump successively.After the drain valve opening time reaches set time, close drain valve, open the air valve that begins to rehearse, now in pump, water level rises, and in pump, air is discharged by outlet pipe.When floating-ball level switch rises when closed with water level, floating-ball level switch input signal is to the DI module of PLC control cabinet, the DO module controls exhaust valve closure of PLC control cabinet.After exhaust valve close, the DO module of PLC control cabinet starts successively water pump, opens outlet valve, completes turn on pump process.
In the time that the DI of PLC control cabinet module receives the termination of pumping instruction from button or upper-position unit, the DO module controls cut-off outlet valve of PLC control cabinet, stops water pump; Then close successively inlet valve, open outlet valve, open drain valve.Start the water in excavationg pump and pipeline.After the water emptying in pump and pipeline, close successively drain valve and outlet valve, complete termination of pumping process.
