Abstract
The utility model relates to a novel pump body used for a submersible sewage pump and convenient in air discharge, which comprises a pump body outlet and a runner and is characterized in that an included angle is formed between the center line of the pump body outlet and the center line of the runner, and the center of the pump body outlet is higher than that of the runner. The novel pump body has the advantage that the water feeding end face of the runner is lower than that of the pump body outlet by means of simple structure improvement, air discharge is facilitated, and normal use of the water pump can be ensured.
Description
Technical field
The utility model relates to the proof submersible sand discharging pump field, particularly a kind of novel pump housing of being convenient to exhaust that is used for proof submersible sand discharging pump.
Background technique
Proof submersible sand discharging pump is submerged in the water and moves, and when putting into water to water pump, the gas in the runner of the pump housing needs to discharge fully, otherwise can influence the performance of water pump.Fig. 1 is the structural representation at the existing structure middle pump body, and the center line of its outlet and the center line of runner are on same straight line.When width of flow path was big, promptly water-outlet quantity was big, caused the last water end (W.E.) face of runner will be higher than the last water end (W.E.) face that the pump housing exports, and the gas in the runner just can't be got rid of fully like this, thereby has influenced the use of water pump.
The model utility content
The utility model provides a kind of novel pump housing of being convenient to exhaust that is used for proof submersible sand discharging pump, to overcome problems such as exhaust is not smooth.
The technological scheme of the utility model is achieved in that a kind of novel pump housing of being convenient to exhaust that is used for proof submersible sand discharging pump; Comprise: pump housing outlet, runner; It is characterized in that: the center line of said pump housing outlet becomes the center of the angle and pump housing outlet to be higher than the center of runner with the center line of runner, thereby guarantees that the outlet upper-end surface is higher than the runner upper-end surface.
The center line of the 8th section to the pump housing outlet of the said pump housing upwards raises equably.
The advantage of the utility model: through simple architecture advances, make the last water end (W.E.) face of runner be lower than the last water end (W.E.) face that the pump housing exports, easy to exhaust guarantees the normal use of water pump.
Description of drawings
Fig. 1 is the prior art constructions schematic representation.
Fig. 2 is the structural representation of the utility model.
Fig. 3 is the outside schematic representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is elaborated.
See also figure; A kind of novel pump housing of being convenient to exhaust that is used for proof submersible sand discharging pump; Comprise: pump housing outlet 3, runner 1 is characterized in that: the center line 4 of said pump housing outlet and the center of 2 one-tenths angles of center line of runner and pump housing outlet are higher than the center of runner, the rising that makes progress equably of the center line of the 8th section 5 to exit portion of the said pump housing; Thereby guarantee that the outlet upper-end surface is higher than the runner upper-end surface, with smooth discharge gas.
The term of using when the 8th above-mentioned section is design pump housing runner waterpower figure, runner waterpower figure is spiral, whenever gets a section at a distance from 45 degree, altogether eight sections (numerous because section has, the artificer can not all draw, so generally just get eight).The artificer provides the shape and size of these eight sections, and the people who makees mould is a benchmark with these eight sections, and with the smooth excessive runner that is joined together to form an integral body of these eight sections.Be shown in the following figure I-VIII section on a center line, and this section is upwards lifted from the VIII section to outlet.
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 (2)
1. novel pump housing of being convenient to exhaust that is used for proof submersible sand discharging pump comprises: pump housing outlet, runner is characterized in that: the center line of said pump housing outlet becomes the angle and the pump housing to export with the center line of runner center is higher than the center of runner.
2. a kind of novel pump housing of being convenient to exhaust that is used for proof submersible sand discharging pump according to claim 1 is characterized in that: the center line of the 8th section to the pump housing outlet of the said pump housing upwards raises equably.
