Description

Pump body and self priming pump

Technical Field

The application relates to the technical field of water pumps, in particular to a pump body and a self-sucking pump.

Background

Most household booster pumps do not have a self-suction function, so when the booster pump is used in a high-rise whole house or under the use working condition that the base water pressure is not high, the product is required to have the self-suction function to increase the negative pressure of the water inlet pipe, and the purpose of increasing the water inlet is achieved. However, most domestic booster pump products in the market at present have no self-suction cavity in the internal structure, belong to centrifugal pumps with straight-through volute structures, and cannot completely cover the special use working conditions of high-rise whole-house boosting or low base water pressure.

Disclosure of Invention

To the not enough of prior art existence, one of the purpose of this application provides a pump body and self priming pump, and it has under the little special use operating mode of high-rise whole house pressure boost or basic water pressure, still can play the advantage of good effect of inhaling.

The application discloses pump body, the novel nipple rectifier comprises a cylindrical shel, the barrel on be equipped with into water section and play water section, the axis of the section of intaking with the axis of play water section mutually perpendicular, the axis of the section of intaking with the axis of play water section between the interval be greater than the impeller that is located the barrel on self axial length direction's width.

By adopting the technical scheme, the water inlet section and the water outlet section are arranged in a staggered manner in a spatial right angle manner, so that strong impact of fluid generated in the pump cavity is reduced, internal energy loss is avoided, the performance of the whole machine is improved, the power consumption of the motor is reduced, the distance between the water inlet and the water outlet is increased, the gas-liquid separation cavity is enlarged, gas and liquid are fully separated, and further the self-absorption effect is better.

The present application may be further configured in a preferred example to: the inner wall of the water outlet section is also provided with an anti-rotation rib which is used for fixing the guide cylinder positioned in the water outlet section.

By adopting the technical scheme, the problem that the guide cylinder positioned in the water outlet section rotates under the impact of water flow is effectively solved, and the measurement accuracy of the flow is improved.

The present application may be further configured in a preferred example to: the water outlet section and the impeller positioned in the barrel are spaced and positioned at the rear end of the water outlet of the impeller.

By adopting the technical scheme, when the water pump is used, the interval between the water outlet section and the impeller positioned in the cylinder body can effectively reduce the impact formed by water flow after the impeller rotates at a high speed and water flow of the water outlet section, the internal energy loss is reduced, and the overall performance of the water pump is further improved.

The present application may be further configured in a preferred example to: the barrel body is also internally provided with a water inlet guide cylinder, the water inlet guide cylinder is communicated with the water inlet section, and an impeller positioned in the barrel body is positioned at the rear end of the water inlet guide cylinder.

Through adopting above-mentioned technical scheme, be equipped with the water inlet guide cylinder in the barrel, with the injection pump contrast, reduced the injection pipe structure, simple structure, convenient assembling.

The present application may be further configured in a preferred example to: the barrel in still be equipped with the tang, the tang be located the barrel and keep away from the one end of intaking the section.

By adopting the technical scheme, the risk of gouging of the seam allowance in the production, transportation and manufacturing processes of the pump body can be reduced.

The present application may be further configured in a preferred example to: the cylinder body is also provided with an outer locking ring which protrudes out of the spigot.

By adopting the technical scheme, the existence of the outer locking ring enables the pump body to be effectively sealed when being connected with the motor, so that water leakage of the pump body is prevented, and the reliability of the pump body is improved.

The application also discloses a self-priming pump, including above-mentioned arbitrary pump body.

Detailed Description

The present application is described in further detail below with reference to the attached drawings.

Referring to fig. 1 and 2, for the pump body that this application discloses, including barrel 1, be equipped with into water section 2 and play water section 3 on barrel 1, the section 2 that intakes sets up in barrel 1 one side, and the axis level of the section 2 that intakes sets up and is mutually perpendicular with the axis of barrel 1, and the axis of the section 3 that goes out sets up vertically and is mutually perpendicular with the axis of barrel 1. The horizontal distance between the axis of the water inlet section 2 and the axis of the water outlet section 3 is larger than the width of the impeller positioned in the barrel 1 in the axial length direction of the impeller.

The inner wall of the water outlet section 3 is provided with anti-rotation ribs 31, and in this embodiment, the anti-rotation ribs 31 are four and the included angle between the adjacent anti-rotation ribs 31 is 90 degrees. The anti-rotation rib 31 is used for abutting against the wall of the guide cylinder arranged in the water outlet section 3 and fixing the guide cylinder.

The water inlet guide cylinder 11 is arranged in the cylinder body 1, the water inlet guide cylinder 11 and the cylinder body 1 are integrally formed, the axis of the water inlet guide cylinder 11 is coincided with the axis of the cylinder body 1, the water inlet guide cylinder 11 is communicated with the water inlet section 2, and the impeller positioned in the cylinder body 1 is positioned at the rear end of the water inlet guide cylinder. The water outlet of the impeller is positioned at the front end of the axis of the water outlet section 3, and the water outlet section 3 is positioned at the rear end of the impeller.

The one end of keeping away from in barrel 1 into water section 2 still is equipped with tang 12, still is equipped with outer locking ring 13 on barrel 1, and outer locking ring 13 protrusion is in barrel 1.

The application also discloses a self-priming pump, including the above-mentioned pump body.

The implementation principle of the embodiment is as follows: when using, because the section 2 of intaking is spatial right angle dislocation with play water section 3 and arranges, go out the interval increase between water section 3 and the section 2 of intaking, consequently the increase of gas-liquid separation chamber, the gas-liquid separation effect is better, also can reduce internal energy loss simultaneously, promotes the wholeness ability of water pump.

The embodiments of the present invention are preferred embodiments of the present application, and the scope of protection of the present application is not limited by the embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
