Title:
SPHERICAL PUMP ROTOR STATIC PRESSURE SUPPORT AND SPHERICAL PUMP PROVIDED WITH STATIC PRESSURE SUPPORT
Document Type and Number:
WIPO Patent Application WO/2021/083019
Kind Code:
A1
Abstract:
A spherical pump rotor static pressure support and a spherical pump provided with said static pressure support. The static pressure support comprises a first liquid flow channel (404) and a second liquid flow channel (405) arranged on a rotating disc (4), liquid pressure-bearing grooves arranged on the two parallel side faces of a shoe (403), and a shoe lining plate (10), the first liquid flow channel (404) comprising a first liquid flow channel inlet (4041) and a first liquid flow channel outlet (4042), the second liquid flow channel (405) comprising a second liquid flow channel inlet (4051) and a second liquid flow channel outlet (4052), and the first liquid flow channel outlet (4042) and the second liquid flow channel outlet (4052) respectively being connected to the liquid pressure-bearing grooves on the two parallel side faces of the shoe (403); the static pressure support is arranged between the two parallel side faces of the shoe (403) and the shoe lining plate (10). The static pressure support ensures that the gap between the spherical surface of the rotating disc and the spherical inner cavity is uniform, reducing friction loss.
