Description
Technical field
The invention belongs to water suction pump device, more particularly to a kind of special pump cover of Miniature water-pumping pump.
Background technology
Suction pump is the effect using atmospheric pressure, and water is promoted to the hydraulic of eminence from lower.It is by water pump, power
Machinery forms with transmission device.It is widely used in the feedwater of field irrigation, draining and industrial and mining enterprises and cities and towns, draining.
Now widely used suction pump, including pump cover, the pump housing, connecting seat, transition connecting seat, bearing block, bearing, transmission
Axle, transmission device, impeller, water seal, wherein, existing pump cover is the lid of one end closing and one end open, it is impossible to root
According to effectively water of the control from the outflow of pump cover delivery port of the pressure in suction pump.
Therefore, a kind of the micro- of water that can effectively control according to the pressure in suction pump and be flowed out from pump cover delivery port is researched and developed
The special pump cover of type suction pump is necessary.
The content of the invention
Can effectively it be controlled from pump cover according to the pressure in suction pump the technical problem to be solved in the present invention is to provide a kind of
The special pump cover of Miniature water-pumping pump of the water of delivery port outflow.
In order to solve the above technical problems, the technical scheme is that：A kind of special pump cover of Miniature water-pumping pump, its innovative point
It is：Include the pump cover body of a lower surface opening, the side of the pump cover body is communicated with delivery port, the pump cover body
Upper surface is provided with a through hole, is fixedly connected with an adjustable plate by screw in the side of the through hole, is provided with the adjustable plate
One arc adjustment hole, and an inner side edge of arc adjustment hole is provided with the convex tendon of several equidistantly distributeds；The pump cover body
Upper surface be additionally provided with one perpendicular to pump cover body adjusting rod, and adjusting rod is located in arc adjustment hole.
Further, the lower surface of the pump cover body is evenly distributed with several projections along its circumferencial direction.
The advantage of the invention is that：
(1) the special pump cover of Miniature water-pumping pump of the present invention, compared with existing pump cover, sets up adjustable plate, by adjustable plate
Arc adjustment hole coordinates with the adjusting rod on pump cover body, is adjusted according to pressure size in pump, and then controls current water outlet
Amount；Meanwhile an inner side edge of arc adjustment hole is provided with the convex tendon of several equidistantly distributeds, and adjusting rod can be made to be fixed on two convex tendons
Between, avoid adjusting rod from being influenceed by pressure in pump, the phenomenon of sideslip occur；
(2) the special pump cover of Miniature water-pumping pump of the present invention, wherein, the lower surface of pump cover body is uniformly distributed along its circumferencial direction
There are several projections, be easy to connecting and fixing for pump cover and body.

One inner side edge is provided with the convex tendon 8 of several equidistantly distributeds；The upper surface of the pump cover body 1 is additionally provided with one perpendicular to pump cover sheet
The adjusting rod 7 of body, and adjusting rod 7 is located in arc adjustment hole.
The special pump cover of the present embodiment Miniature water-pumping pump, compared with existing pump cover, adjustable plate 5 is set up, by adjustable plate 5
Arc adjustment hole 6 coordinates with the adjusting rod 7 on pump cover body 1, is adjusted according to pressure size in pump, and then controls water outflow
Water；Meanwhile an inner side edge of arc adjustment hole 6 is provided with the convex tendon of several equidistantly distributeds, and adjusting rod 7 can be made to be fixed on two
Between convex tendon, avoid adjusting rod from being influenceed by pressure in pump, the phenomenon of sideslip occur.
In embodiment, for the ease of connecting and fixing for pump cover and body, in the lower surface of pump cover body along its circumferencial direction
It is evenly distributed with several projections.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
For art personnel it should be appreciated that the present invention is not limited to the above embodiments, described in above-described embodiment and specification is explanation
