Abstract
The utility model relates to an economical pump body for a small-sized submersible sewage pump, which comprises an upper flange, an outlet flange and a volute. The economical pump body is characterized in that three rib plates distributed circumferentially and evenly are connected between the upper flange and the volute, and outer walls are connected among two rib plates, the outlet flange and the volute so that an oil chamber is formed. The economical pump body has the advantages that the economical pump body is simple in structure, the weight of the pump body is reduced, consumption of lubricating oil is decreased, the working procedure of drilling is omitted, and production cost is reduced.
Description
Technical field
The utility model relates to a kind of pump housing that is used for the small-sized proof submersible sand discharging pump of power below 4KW, particularly to the improvement of pump body structure.
Background technique
The output of small-sized proof submersible sand discharging pump is very big, reduces its cost and not only can create more profit, can also get the mastery in competition.Because the pump housing and the pump cover of the small-sized proof submersible sand discharging pump of power below 4KW are cast in together,, can reduce production costs if can alleviate the weight of the pump housing or reduce manufacturing procedure so the pump housing has just become weight maximum and the maximum part of manufacturing procedure.In view of the foregoing, demand developing a kind of novel economical pump housing that is used for small-sized proof submersible sand discharging pump urgently, to satisfy the demand that people improve constantly.
Summary of the invention
The purpose of this utility model has provided a kind of impeller and pump cover that is used for proof submersible sand discharging pump, has solved the deficiencies in the prior art.The purpose of this utility model is achieved in that a kind of economical pump housing that is used for small-sized proof submersible sand discharging pump, comprise: upper flange, outlet(discharge) flange, spiral case, it is characterized in that: be connected with 3 circumferential equally distributed gussets in edge between described upper flange and the spiral case, be connected with outer wall between two gussets therein, outlet(discharge) flange, the spiral case, form a grease chamber.
Circumferentially be distributed with 4 U-shaped holes on the described flange mouth.
Have oil filler on the described outer wall.
The utility model has the advantages that: simple in structure, alleviated the weight of the pump housing, reduced the lubricant oil consumption, saved the operation of boring, reduced cost of production.
Description of drawings
Accompanying drawing 1 is the utility model plan view; Accompanying drawing 2 is the utility model left view; Accompanying drawing 3 is the C-C cross-section cutaway view; Accompanying drawing 4 is the outlet(discharge) flange plan view.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Among the figure, a kind of economical pump housing that is used for small-sized proof submersible sand discharging pump, comprise: upper flange 2, outlet(discharge) flange 1, spiral case, it is characterized in that: be connected with 3 circumferential equally distributed gussets 5 in edge between described upper flange 2 and the spiral case 3, be connected with outer wall 8 between two gussets 5 therein, upper flange 2, the spiral case 3, form a grease chamber 4.
4 U-shaped holes 7 are arranged on the described outlet(discharge) flange mouth 1.
Circumferentially be distributed oil filler 6 on the described outer wall 8.
The utility model has kept the advantage of original structure: promptly the pump housing and pump cover are cast as one, can reduce whole weight and amount of finish like this.Done following improvement simultaneously: among Fig. 2, link to each other by 3 equally distributed gussets between upper flange and the volute; It is original 1/3rd that outer wall is reduced to, and promptly between two gussets below only outer wall arranged, and outer wall reduces to alleviate the weight of the pump housing; It is original 1/3rd that the volume of grease chamber is reduced to, and as shown in Figure 4, the cavity that following two gussets and outer wall and inwall fence up is the grease chamber, because grease chamber's volume reduces, so the lubricant oil volume of required adding has just reduced much than original; Directly cast out 4 " U " shape holes on the outlet(discharge) flange, so just need not reprocess through hole, saved the operation of boring.
Only expressed mode of execution of the present utility model more than 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 protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
The utility model advantage is: simple in structure, alleviated the weight of the pump housing, and reduced the lubricant oil consumption, saved the operation of boring, reduced cost of production.
