Abstract
The utility model relates to a liquid uptake and discharge apparatus for a self-suction pump, wherein, a rotor is eccentrically arranged in a pump body, and the rotor is provided with a vane groove; the bottom of the vane groove is provided with a spring, a vane is withstood by the spring so as to keep seal situation between the vane and an inner wall of the pump body. The utility model is characterized in that the thickness of the vane groove is larger than the thickness of the vane, the vane is arranged in one side of the vane groove, and the other side is provided with a liquid inlet hole. The utility model overcomes defects existing in the liquid uptake and discharge apparatuses of ordinary self-suction pumps of limited seal ability between the vanes and the inner walls of the pump boies. The utility model has the advantages of simple structure and outstanding seal effect.
Description
The utility model relates to a kind of self-priming pump suction liquid device.
Self-priming pump suction liquid device generally comprises the blade in the pump housing, rotor and the rotor vane groove, rotor eccentricity is arranged in the pump housing, make and form a crescent shape gap between the pump housing and rotor, when blade in the pump housing with the rotor period of rotation touch or when leaving the crescent-shaped land, the telescopic action of blade changes the volume between blade and crescent-shaped land, forms the suction liquid effects of self-priming pump.And self-priming pump can keep suction liquid incessantly, touches the seal degree decision of pump housing inwall when mainly being rotated by blade.In the prior art, the determinant factor of the seal degree between decision blade and pump housing inwall is the centrifugal force that blade produces when rotated, and additive factor is arranged on the tension force of the spring of blade bottom, in addition, does not have new scheme again.
The purpose of this utility model is improved on the basis of existing technology again, thereby a kind of technology, simple in structure is provided, the self-priming pump suction liquid device that seal degree is better.
The utility model comprises the pump housing, rotor, rotating shaft and blade, rotor eccentricity is arranged in the pump housing, rotor is provided with blade groove, the bottom of blade groove is provided with spring, and spring withstands blade, makes blade and pump housing inwall be sealing configuration, for improving seal degree, the thickness of blade groove is greater than the thickness of blade in the utility model, and blade is arranged on a side of blade groove, and opposite side is provided with inlet opening.
Below in conjunction with drawings and Examples detailed content of the present utility model is described.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises the pump housing 1, rotor 2, rotating shaft 3 and blade 4, rotor 2 is eccentrically set in the pump housing 1, make and form a crescent shape gap 8 between rotor 2 and pump housing inwall, rotor 2 is provided with blade groove 5, the bottom of blade groove 5 is provided with spring 6, and spring 6 withstands blade 4, makes blade 4 and pump housing inwall be sealing configuration.In order to improve the tightness degree of sealing, the thickness of blade groove 5 is greater than the thickness of blade 4 in the utility model, and blade 4 is arranged on the side in the blade groove 5, and opposite side is provided with inlet opening 7.When the starting stage that pump uses, tension force by spring 6 ejects the blade in the blade groove 54, reach sealing state and produce the self-priming effect, after treating that liquid sucks, the liquid stream at high pressure position enters blade 4 bottoms by inlet opening 7 parts, thereby produce bigger thrust blade 2 is ejected, thereby reach better sealing effect.
The utility model improves the sealability of self-priming pump suction liquid device greatly, and does not increase technology by above-mentioned concrete structure, the complexity of structure, according to test, the utility model is being done under the operating condition, vacuum can reach 0.5MP, is a kind of desirable self-priming pump suction liquid device.
