High performance sanitary pump

Abstract

The present invention relates to a high-performance sanitary pump wherein an impeller (20) rotationally driven by a motor (M) is axially installed in an inner portion of a case (10) to suction and discharge a fluid by using a rotating centrifugal force of the impeller. Moreover, the impeller (20) radially connects a discharge tube (22) to a cylindrical suction groove portion (21) at equal angles to suction and discharge the fluid with pressure to induce smooth flow instead of forced pressure to forcibly push the fluid by a conventional rotating wing, thereby enabling operation with low noise and vibration and providing high performance with high lift and flow rates.

Description

technical field [0001] The present invention relates to a high-performance sanitary pump that sucks and discharges fluid through the rotating centrifugal force of the impeller. Specifically, the impeller is not forced to push out through the existing rotating blades, but is arranged radially on the circumference of the suction groove. The discharge pipe induces soft flowing pressure and high pressure suction and discharge, realizes low noise, low vibration operation, and realizes high performance high performance sanitary pump with high head and flow rate. Background technique [0002] Pumps are generally classified into different types such as reciprocating pumps, rotary pumps, centrifugal pumps, axial flow pumps, friction pumps, etc. according to their structures and uses. The centrifugal pumps are one of the most widely used pumps in the industrial field. [0003] The centrifugal pump is provided with a spiral channel on the outside of the rotating impeller (rotating wing...

AI Technical Summary

Problems solved by technology

[0004] The impeller of the existing centrifugal pump is that the impeller of the curved surface forms a radial shape on the circumference at an equiangular angle, and rotates in a state close to the front cover of the housing while sucking and discharging the fluid by centrifugal force, and by The rotor of the impeller sucks and discharges the fluid by forcing it out. Due to the friction and impact with the fluid, large vibration and noise occur, and it is impossible to achieve high performance with high head and flow rate.

[0005] As mentioned above, in order to reduce the vibration and noise generated by the drive of the impeller of the pump and improve the performance, more efforts have been made technically to try to design the rotor blade of the impeller more precisely to improve the vibration and noise of the pump and Performance problems, but the impeller's rotor blades are forced to push the fluid out, so the problems of vibration and noise and performance improvement cannot be completely solved
