Description

Automatic exhaust device for boats and ships water system
Technical field
The utility model relates to a kind of water system peculiar to vessel, particularly discloses a kind of automatic exhaust device for boats and ships water system.
Background technology
At present, known water system peculiar to vessel is by booster pump, to be connected to by the road water pressure tank to be controlled and realized automatic water-supply by pressure switch.Booster pump mostly wherein is centrifugal pump, often wants manual exhaust in operation process, as fails timely exhaust, booster pump is again when automatic running status, shaft seal just may be in dry operating condition, shortens Pump Shaft Seal application life, increases maintenance cost and even supplies water difficulty and occur emergency situation.
Summary of the invention
The purpose of this utility model is to overcome the defect existing in prior art; provide a kind of and can realize automatic vent; thereby protection booster pump shaft seal, has self-suction function simultaneously, make the more convenient stable automatic exhaust device for boats and ships water system of water system operation.
The utility model is achieved in that a kind of automatic exhaust device for boats and ships water system, it is characterized in that: comprise charging tank, compressed air electromagnetic valve, exhaust solenoid valve, electric control box, pressure switch, booster pump, liquid-level switch, vacuum ejector; Described charging tank is provided with electric control box, and described electric control box is connected with described pressure switch, compressed air electromagnetic valve, exhaust solenoid valve, liquid-level switch, booster pump respectively; Described vacuum ejector is connected with described compressed air electromagnetic valve, exhaust solenoid valve respectively, and described exhaust solenoid valve is also connected with described liquid-level switch, and described liquid-level switch is connected with described booster pump, and described booster pump is connected with described charging tank.
The float liquid level switch that the gas that described liquid-level switch makes to produce in described booster pump for the lifting by float is discharged via vacuum ejector.
The beneficial effects of the utility model are: can realize automatic vent, avoid the dry running of pump, reduce the uncertainty of manual operation, extend booster pump service life, realize unmanned, have self-suction function simultaneously concurrently, simple in structure, there is excellent practicality, simplicity, stability and generalization.
Accompanying drawing explanation
Fig. 1 is the utility model external structure schematic diagram.
Fig. 2 is the utility model structure connection diagram.
Wherein: 1, compressed air electromagnetic valve; 2, exhaust solenoid valve; 3, charging tank; 4, electric control box; 5, pressure switch; 6, booster pump; 7, liquid-level switch; 8, vacuum ejector.
The specific embodiment
According to Fig. 1, Fig. 2, the utility model comprises charging tank 3, compressed air electromagnetic valve 1, exhaust solenoid valve 2, electric control box 4, pressure switch 5, booster pump 6, liquid-level switch 7, vacuum ejector 8.Described charging tank 3 is provided with electric control box 4, and described electric control box 4 is connected with described pressure switch 5, compressed air electromagnetic valve 1, exhaust solenoid valve 2, liquid-level switch 7, booster pump 6 respectively; Described vacuum ejector 8 is connected with described compressed air electromagnetic valve 1, exhaust solenoid valve 2 respectively, described exhaust solenoid valve 2 is also connected with described liquid-level switch 7, described liquid-level switch 7 is connected with described booster pump 6, and described booster pump 6 is connected with described charging tank 3 by pipeline.
When the utility model is used, by pressure switch 5, start electric control box 4, compressed air electromagnetic valve 1 and exhaust solenoid valve 2 are opened, vacuum ejector 8 is open-minded, air in booster pump 6 and pipeline can be at exhaust solenoid valve 2, under the effect of liquid-level switch 7, by vacuum ejector 8, discharge, if the float of liquid-level switch 7 does not float (when the interior air emptying of booster pump 6, liquid level promotes, the float of described liquid-level switch 7 floats, gas air accumulation in booster pump 6 cavitys after operation a period of time, the interior liquid level of liquid level collecting pipe that connects booster pump 6 declines, the float of described liquid-level switch 7 falls), booster pump 6 can not move, whole pipe-line system (comprising booster pump 6 and preceding pipeline thereof) before the exhaust solenoid valve 2 connecting due to the suction inlet of vacuum ejector 8, exhaust opening by vacuum ejector 8 is discharged, vacuum ejector 8 suction inlet vacuums are larger, exhaust velocity is faster, exhaust process is different according to pipeline volume, may continue several minutes.
After the float of liquid-level switch 7 floats, after through electric control box 4, interior time-delay relay time delay is connected, compressed air electromagnetic valve 1 and exhaust solenoid valve 2 are closed, booster pump 6 entrys into service.
If have air in the pipeline between described booster pump 6 and described charging tank 3; the float of described liquid-level switch 7 can fall again; after through electric control box 4, interior time-delay relay time delay is connected; described booster pump 6 will shut down, and then re-starts exhaust action, and compressed air electromagnetic valve 1 and exhaust solenoid valve 2 are opened; vacuum ejector 8 is open-minded; air in booster pump 6 and pipeline can be discharged by vacuum ejector 8, and so circulation guarantees that booster pump 6 runs well and protects the shaft seal of booster pump 6.Under the effect of described liquid-level switch 7, can make booster pump 6 have self-suction function, operation is front without pump priming, simple operation simultaneously.
