Title:
MULTI-BLADE SUCTION AND DISCHARGE APPARATUS HAVING AXIALLY-VARIABLE VOLUME AND VARIABLE SPEED DRIVE SYSTEM COMPOSED OF SAME
Document Type and Number:
WIPO Patent Application WO/2022/028523
Kind Code:
A1
Abstract:
A multi-blade suction and discharge apparatus having axially-variable volume. A blade chamber body (2) of a multi-offset blade chamber area (2203) capable of axially changing the volume of a blade chamber (220) along a multi-blade rotor (3) is jointly formed inside of an impeller-type suction and discharge apparatus (100) by a fixed wall member (21), a movable blade chamber sleeve (22), and a movable wall member (23) by using the multi-blade rotor (3) as the center. The total amounts of fluid that are suctioned and discharged by the suction and discharge apparatus (100) are nearly equal. At least two suction and discharge apparatuses (100) communicate with one another so as to form a closed-loop system having active and passive driving. On the basis of the balancing of forces being automatically attained between driving force and load resistance, as well as the inverse proportional relationship between the volume of the blade chamber (220) of the suction and discharge apparatus (100) and rotational speed, the rotational speed between the active and passive suction and discharge apparatuses is at an optimal driving ratio, thereby achieving optimal stepless automatic variable speed drive. Further provided is a variable speed drive system comprising a multi-blade suction and discharge apparatus having axially-variable volume.
