Abstract
The utility model relates to a pump cover for a submersible sewage pump. The pump cover comprises a connecting flange arranged in a pump cover body, a pump casing and a connecting base, and is characterized in that a plurality of lugs extending outwards are evenly distributed along the circumferential direction at the outer edge of the connecting flange, and threaded blind holes are arranged downwards on the end faces where the lugs are contacted with the connecting base. The pump cover for the submersible sewage pump has the advantages of being simple in structure and easy to implement, thoroughly solving the problem of the increased thickness of an original connecting flange, greatly reducing manufacturing cost, and lightening weight of the pump cover.
Description
Technical field
The utility model relates to the proof submersible sand discharging pump field, particularly a kind of pump cover that is used for proof submersible sand discharging pump.
Background technique
In proof submersible sand discharging pump, pump cover, casing, connecting base three link together through screw.Wherein, pump cover is positioned at bottom, and in the middle of connecting base was positioned at, casing was positioned at topmost.To process on the adpting flange of pump cover and be provided with the tapped hole that supplies above-mentioned screw to wear; But because structural limitations, tapped hole must be processed into blind hole, can not be processed into through hole; This just needs to increase the thickness of adpting flange, and the increase of thickness causes manufacture cost to increase and whole pump cover weight is promoted.
The model utility content
The utility model provides a kind of pump cover that is used for proof submersible sand discharging pump, to overcome the problems such as manufacture cost height of existing technology.
The technological scheme of the utility model is achieved in that a kind of pump cover that is used for proof submersible sand discharging pump; Comprise: the adpting flange in the pump cover body, casing and connecting base; It is characterized in that: said adpting flange outer rim circumferentially is evenly distributed with the lug that plurality of outward is extended along it, offers tapped blind hole downwards on each lug and the end face that connecting base contacts.
Preferably, said lug has 6-12.The concrete quantity of lug is decided according to the weight of submersible pump, and weight is big more, and lug quantity is also many more.
Preferably, the least significant end of said tapped blind hole is 8mm to the lower end surface of lug.
The advantage of the utility model: simple in structure, easy to implement, thoroughly solved the difficult problem of adpting flange thickness increase originally, reduce the cost of making pump cover greatly, and alleviated the weight of pump cover.

1, pump cover body 11, adpting flange 12, lug 13, tapped blind hole 2, connecting base 3, casing 4, screw.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
See also figure; A kind of pump cover that is used for proof submersible sand discharging pump; Comprise: the adpting flange in the pump cover body, casing and connecting base is characterized in that: said adpting flange outer rim circumferentially is evenly distributed with the lug that plurality of outward is extended along it, on each lug with the fitting surface of connecting base on to having tapped blind hole; The least significant end of tapped blind hole is 8mm to the lower end surface of lug; And the diameter of lug is 2-3 times of used screw thread diameter, can satisfy the wall thickness requirement like this, and the thickness of lug is decided according to the degree of depth of tapped blind hole.
Said lug has 6.Because the quantity of lug is few, volume is little, the weight of its increase is very limited, has thoroughly solved the problem that adpting flange will be thickeied, and significantly reduces manufacture cost.
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.
Claims (3)
