Abstract
The utility model relates to a convenient-to-dismount pump cover of a submerged sewage pump, which comprises a pump cover body. The outer rim of the pump cover body is uniformly provided with a plurality of outwardly extending lugs along the circumferential direction thereof. The lugs are provided with positioning holes for screws to pass through. The pump cover is characterized in that the contact end surfaces of the lugs and the pump body are provided with an unfilled corner along the outer rim thereof. The contact end surfaces of the unfilled corner, the pump body and the lugs are provided with a dismounting groove. The convenient-to-dismount pump cover of a submerged sewage pump provided by the utility model has the advantages of simple structure, convenient and easy operation, time saving and labor saving, which greatly reduces the dismounting difficulty of the pump cover and the pump body.
Description
Technical field
The utility model relates to the proof submersible sand discharging pump field, particularly a kind of easy-to-dismount pump cover that is used for proof submersible sand discharging pump.
Background technique
The pump housing of proof submersible sand discharging pump and pump cover lean on seam to cooperate, and interconnect fixing through the lug that screw passes pump cover.Because the medium that proof submersible sand discharging pump is pumped is a sewage, these sewage often all have corrosivity, and the time one is long, is easy to make the pump housing, pump cover and screw corrosion, make the staff when safeguarding, dismantle very difficulty of pump cover.
The model utility content
The utility model provides a kind of easy-to-dismount pump cover that is used for proof submersible sand discharging pump, to overcome the problems such as dismounting difficulty of existing technology.
The technological scheme of the utility model is achieved in that a kind of easy-to-dismount pump cover that is used for proof submersible sand discharging pump; Comprise: the pump cover body; The outer rim of pump cover body circumferentially is evenly distributed with the lug that plurality of outward is extended along it; This lug is provided with the positioning hole that supplies screw to wear, and it is characterized in that: the end face that said lug contacts with the pump housing offers a unfilled corner along its outer rim, and this unfilled corner forms a dismounting groove with the end face that the pump housing contacts with lug.
Preferably, the cross section of said unfilled corner is 1/4th circular arc.
Preferably, the radius 5mm of said circular arc.
The advantage of the utility model: simple in structure, convenient and easy, time saving and energy saving, greatly reduce the dismounting difficulty of the pump cover and the pump housing.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the longitudinal sectional view of Fig. 1.
Fig. 3 is the use schematic representation of the utility model.
1, pump cover body 11, lug 12, unfilled corner 13, end face 2, the pump housing 3, dismounting groove 4, screw.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
See also figure; Shown in the figure is a kind of easy-to-dismount pump cover that is used for proof submersible sand discharging pump; Comprise: pump cover body 1, the outer rim of pump cover body circumferentially is evenly distributed with the lug 11 that plurality of outward is extended along it, and this lug is provided with the positioning hole that supplies screw 4 to wear; It is characterized in that: the end face 13 that said lug contacts with the pump housing offers the unfilled corner 12 that a cross section is the circular arc of R=5mm 1/4th along its outer rim, and this unfilled corner forms a dismounting groove 3 with the end face that the pump housing contacts with lug.
When the dismounting pump cover,, thereby pump cover is dismantled more easily as long as the staff utilizes crow bar to prize the dismounting groove between the pump cover body and the pump housing.
Below only expressed the mode of execution of the utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
The advantage of the utility model: simple in structure, convenient and easy, time saving and energy saving, greatly reduce the dismounting difficulty of the pump cover and the pump housing.
