Cabin pipe 8 being opened or closing, and the first control valve 12 connects control system 11；The material of high liquid level sweeping pipe 8 is 316 stainless
Steel, the nominal diameter of high liquid level sweeping pipe 8 determine according to the model of the selected pump housing 5, high liquid level sweeping pipe 8 in the utility model
Nominal diameter is greater than 150mm.
Due to 5 cavitation of the pump housing, when a small amount of liquid remaining in cabin, the pump housing 5 can not discharge it cabin, and due to
The nominal diameter of high liquid level sweeping pipeline provisioned in traditional pump housing 5 in 150mm or more, pipeline height sometimes up to 4m with
On, therefore a part of liquid can be retained in pipeline can not be discharged, the liquid retained when device is out of service can fall back to cabin
It is interior, so that sweeping is not thorough；Therefore, the utility model is provided with low liquid level sweeping component.
Low liquid level sweeping component includes low liquid level sweeping pipe 9, and low liquid level sweeping pipe 9 is upward through fixed plate 3 and is fixed on
In fixed plate 3, the switch of low liquid level sweeping pipe 9 is electrically connected the second control valve 13, and the second control valve 13 can control low liquid level and sweep

Control system 11, control system 11 starts the first control valve 12, while starting variable-frequency motor 1 and running at high speed, high liquid level sweeping pipe 8
Liquid in cabin is delivered on deck；Since cavitation can occur under high-speed rotation for the pump housing 5, when liquid level is lower than one in cabin
When determining height, low liquid level liquid can not be delivered on deck by the pump housing 5, meanwhile, remaining part liquid in high liquid level sweeping pipe 8
Body can be also back in cabin due to gravity；At this point, low liquid level signal is fed back to control system 11 by level sensing structure,
Control system 11 closes the first control valve 12, opens the second control valve 13, while controlling 1 reduction of speed of variable-frequency motor, the pump housing 5 is at low turn
The lower operating of speed, the cavitation of the pump housing 5 reduce, and low liquid level sweeping pipe 9 continues on to liquid remaining in cabin on deck, by ship
Low liquid level liquid is cleaned out in cabin.
In conclusion high liquid level sweeping component and low liquid is respectively set by two outlet ends in the pump housing in the utility model
Position sweeping component, low liquid level sweeping pipe is curved equipped with damping expansion, and the utility model also sets up level sensing structure, level sensing
Device can measure the lowest water level of liquid in the cavitation water level and cabin of the peak level of liquid in cabin, the pump housing；When in cabin
When liquid level is higher, high liquid level signal is fed back to by control system by level sensing structure, control system starts high liquid level sweeping
Component operation；When liquid level is lower in cabin, low liquid level signal is fed back to by control system, control system by level sensing structure
System starting low liquid level sweeping component operation, low liquid level liquid in cabin is cleaned out, meanwhile, the damping on low liquid level sweeping pipe
Expansion bends can reduce caused pipeline vibration in liquid delivery process, extend the service life of low liquid level sweeping component.To sum up,
The utility model has the following beneficial effects: structure is simple, and it is easy to operate, it can effectively solve the low liquid level liquid occurred when ship sweeping
The problem of body can not be cleaned out, while level sensing structure connects control system, can be realized high liquid level sweeping component and low
