Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides the following technical solutions: the utility model provides a submerged motor pump, includes drive end 1, and drive end 1 is connected with output section 4, and output section 4 is connected with delivery outlet 5, and 4 inside one side that is close to delivery outlet 5 of output section are provided with filter plate 12, and a plurality of filtration pores have been seted up on the surface of filter plate 12, and one side that delivery outlet 5 was kept away from to filter plate 12 is provided with valve body 9, and valve body 9 corresponds with the filtration pore towards the one end of filter plate 12 and is provided with end cap 13. The inner wall of the output section 4 is conical, the large opening of the cone (i.e. the conical surface 8) faces the output opening 5, and the diameter of the valve body 9 is smaller than that of the large opening of the cone. An expansion shaft 10 is connected between the filter plate 12 and the valve body 9, an elastic member 11 is sleeved on the surface of the expansion shaft 10, and the elastic member 11 can be an elastic member with supporting force such as a spring, an air cylinder and the like.
A filter mantle 2 is arranged between the driving end 1 and the output section 4, the filter mantle 2 is hollow, and a plurality of through holes are arranged on the surface of the filter mantle 2. A pressurizing section 3 is connected between the filter mantle 2 and the output section 4, the driving end 1 is connected with a transmission shaft 6, the transmission shaft 6 is positioned inside the pressurizing section 3, and a pressurizing assembly is arranged on the surface of the transmission shaft 6. The pressurizing assembly comprises a plurality of centrifugal impellers 7.
The working principle is as follows: when the electric pump starts to work, the whole device can be placed in water, then the driving end 1 is started, the driving end 1 can drive the transmission shaft 6 to rotate, and the transmission shaft 6 can drive each centrifugal impeller 7 to rotate. After rotation of the centrifugal impeller 7, it generates a certain centrifugal force, which draws in water from the filter housing 2 and discharges it rapidly in the direction of the outlet section 4. After accelerated discharge through a series of centrifugal impellers 7, the water enters the output section 4 and impacts the valve body 9.
When the water flow impacts the valve body 9, the valve body 9 will move towards the direction of the filter plate 12, and because the tapered large opening faces the output port 5, the diameter of the valve body 9 is smaller than that of the tapered large opening, so that after the valve body 9 moves towards the filter plate 12, the water flow will flow out to the output port 5 from the gap between the tapered surface 8 and the valve body 9.
At a faster flow rate, the distance it moves to push the valve body 9 against the elastic force of the elastic member 11 will be side length. When the valve body 9 is pushed to be in contact with the filter plate 12 by water flow, the flow rate of the water flow is high at the moment, and the filter holes are blocked by the plugs 13, so that the filter plate 12 can cut off the output of the water flow at the moment, and the impact strength of the water flow with the high flow rate on subsequent components can be reduced.
