Title:
COOLANT OR HEATING FLUID CIRCULATION SYSTEM OF DUAL-SUPPORT CENTRIFUGAL PUMP
Document Type and Number:
WIPO Patent Application WO/2016/058451
Kind Code:
A1
Abstract:
A coolant or heating fluid circulation system of a dual-support centrifugal pump, provided with a left bushing (21) and a right bushing (22) that are sleeved on a pump shaft (1), a first left-side sealing gland (31) and a second left-side sealing gland (32) that are sleeved on the periphery of the left bushing (21) via a left-side atmospheric-end sealing static ring (16), a left-side atmospheric-end sealing dynamic ring (10), and a left-side medium-end sealing static ring (11), a first right-side sealing gland (51) and a second right-side sealing gland (52) that are sleeved on the periphery of the right bushing (22) via a right-side atmospheric-side sealing static ring (18), a right-side atmospheric-end sealing dynamic right (12), and a right-side medium-end sealing static ring (13), and a heat exchange fluid circulation channel that is formed among the first left-side sealing gland (31), the second left-side sealing gland (32), the left bushing (21), the pump shaft (1), the right bushing (22), the first right-side sealing gland (51), and the second right-side sealing gland (52) and is connected to a heat exchanger (7) to allow a heat exchange fluid to flow in the axial direction of a rotating component while rotating synchronously with the rotating component. Cooling or heating is provided directly to a part at where either cooling or heating is needed most, thus allowing the temperature of the rotating component to be controlled within a set range at all times.
