Abstract
A self-priming pump pertains to pump, comprising a pump cover, a pump seat, a motor, a pump shaft, a pump casing, a pump lid and an impeller. The pump shaft disposed inside the pump seat inner chamber is fixed together with the right output head of the motor disposed inside the pump cover by a screw hole shaft coupling and a through hole shaft coupling. The pump casing is disposed at the right side of the pump seat and connected therewith by a hexagon-headed bolt. The pump lid is connected at the right side of the pump casing by a lid-shaped screw cap and a stud. The impeller is disposed on the pump shaft inside the pump casing inner chamber, and a shaft seal cover is disposed at the right end of the pump shaft, and the bottom of the pump cover is connected with foundation components by a square steel. Compared to prior art, the self-priming pump of this utility model has characteristics of strong self-priming capability, no damage to material and no retained material. The pump is widely applied to prime materials in various occasions when the liquid level is unstable, even lower than the inlet of the pump, especially in CIP (Clean In Place) system as reflux pump.
Description
Technical field
The utility model relates to a kind of pump, and specifically a kind of suction capacity by force, is not damaged material, is not detained a kind of self-priming pump of material.
Background technique
Exist multiple self-priming pump on the market, but because the difference that does not reach material application that itself designs makes it exist various deficiencies in practice comprehensively, because design is unreasonable, can stay the dead angle in product inside, after long-term the use, can form detained matter at the liquid parts of crossing of pump, the mechanical sealing element material property is not good, suction capacity is not good, add its material application and do not meet sanitary standard, be easy to damage material, what have also can corrode material.
Summary of the invention
Technical assignment of the present utility model provides a kind of self-priming pump, has solved problem or defective that the central self-priming pump of prior art is detained material, damages material, suction capacity difference.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of self-priming pump, structure comprises the pump cover, pump seat, motor, pump shaft, pump case, pump cover, impeller, the pump shaft that is arranged in the pump seat inner chamber is fixed together with the right-hand member delivery that is arranged on the motor of pump cover inside by screw shaft joint and through hole shaft joint, pump case is arranged on the right side of pump seat and is attached thereto by hexagon head bolt, pump cover is connected the right side of pump case by lid type nut and double-screw bolt, pump shaft in the inner chamber of pump case is provided with impeller, be provided with shaft seal cover at the pump shaft right-hand member, the bottom of pump case is connected with the lower margin assembly by square steel.
Between pump cover and pump case, also be provided with seal ring.
Described pump shaft stage casing is connected with pump case with stationary ring O type circle by stationary ring, is with fastening lasso of rotating ring and rotating ring successively at the right side of stationary ring pump shaft, and rotating ring O type circle is sealed between rotating ring and the impeller.
On described stationary ring, also be provided with stop pin and Packing spring.
The circumference of pump seat is provided with the shaft joint guard shield.
Described impeller is a radial pattern.
The described square steel outside that is connected with the pump case also is provided with cushion cover.
A kind of self-priming pump impeller of the present utility model is radial pattern, pump case and pump cover are formed the inner chamber of pump, when rotating in the inner chamber of impeller at pump, the volume that impeller spoke and inner chamber are formed, play increase gradually by suction port, the volume of forming to the exhaust port place progressively reduces, and therefore makes the liquid that comprises in the impeller spoke, can become the reciprocating action of suction and discharge opeing, form certain suction capacity.
A kind of self-priming pump of the present utility model is compared with prior art, having suction capacity by force, does not damage material, is not detained characteristics such as material, it is unstable that this pump is widely used in the liquid level height, even the various occasions that the liquid position is lower than the import of pump draw materials, particularly are used as reflux pump in the purging system on the spot at CIP.
