Description
Technical Field
The invention relates to the technical field of centrifugal pumps, in particular to a box-shaped self-priming centrifugal pump.
Background
The self-priming centrifugal pump can send water out due to the action of centrifugal force. Before the water pump works, the pump body and the water inlet pipe are filled with water to form a vacuum state. When the impeller rotates rapidly, the blades promote the water to rotate rapidly, and the rotating water flies away from the impeller under the action of centrifugal force. After the water in the pump is thrown out, a vacuum area is formed at the central part of the impeller. The water of the water pump is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). Therefore, continuous water pumping can be realized after circulation. It is worth mentioning here that: before starting the self-priming centrifugal pump, the pump casing must be filled with water.

In the present embodiment, the specific operation steps are as follows, when the driving motor 22 is started, the self-priming centrifugal pump main body 21 is driven to operate through the power transmission shaft 23. While being engaged with the first transmission gear 313 through the second transmission gear 314 provided on the power transmission shaft 23.

The backflow preventing connection plate 410 is vertically disposed in the vent 13. The air inflow and outflow holes 411 are provided in a plurality, and the air inflow and outflow holes 411 are opened in the backflow preventing connection plate 410.

The dust intercepting assembly 42 includes: a dust intercepting net 420 and a fixing bolt 421. The dust intercepting net 420 is vertically disposed in the ventilation opening 13. The dust intercepting net 420 is positioned at an outer side of the backflow preventing connecting plate 410. And the bottom end of the dust intercepting net 420 is not connected to the bottom wall of the ventilation opening 13. The fixing bolt 421 serves to fix the dust intercepting net 420 in the ventilation opening 13.
Further, in order to make the wind generated by the rotating fan 321 quickly disperse dust and moisture in the inner cavity of the protection housing 11. The dust cleaning mechanism 40 is also arranged on the side wall of the protective box body 11. The wind backflow prevention assembly 41 provided inside the dust removing mechanism 40 enables wind generated by the rotating fan 321 to carry dust and moisture by blowing the rotating connection plate 412. And the air is blown out from the inside of the air inlet/outlet hole 411 and then blown out of the inner cavity of the protective box body 11 through the dust intercepting net 420.
