[0010] The present invention will be further described below in conjunction with the drawings and embodiments.

[0011] Such as Figures 1 to 3As shown in the figure, a housing assembly for collecting and sealing the cooling water entering the permanent magnet speed regulator includes a lower housing (1), an upper housing (2), a breather cap (3), a flange lens (4), a TC cap (5), an inlet hose (6), a load end return pipe (7), a straight through quick connector (8), a housing seal ring (9), an inspection cover (10), a load water collecting tank (11), a load water baffle (12), a motor water baffle (13), a motor water collecting tank (14), a motor end return pipe (15), a load end seal ring (16), a one-piece ball valve (17), a motor end seal ring (18), a movable cover (19), a movable cover seal ring (20), a seal ring pressing plate A (21), a fluororubber seal ring A (22), a silicone rubber seal ring A (23), a seal ring pressing plate B (24), a fluororubber seal ring B (25), and a silicone rubber seal ring B (26).

[0012] The conductor rotor (30) is concentrically arranged on the motor shaft (28) and rotates and moves left and right synchronously with the motor shaft (28); the permanent magnet rotor (29) is concentrically sleeved with the conductor rotor (30) and is separated by an air gap; the permanent magnet rotor (29) is concentrically arranged on the load shaft (27) and drives the load shaft (27) to rotate. The housing assembly and the load shaft (27) are concentrically arranged and the corresponding positions are adjusted.

[0013] During operation, the permanent magnet rotor (29) and the conductor rotor (30) are in a disengaged state. At this time, the conductor rotor (30) and the motor shaft (28) are in the rightmost position. The cooling water enters the permanent magnet rotor (29) and the conductor rotor (30) of the high-speed rotating permanent magnet speed regulator through the inlet hose (6), then flows out through the air gap between the permanent magnet rotor (29) and the conductor rotor (30), enters the lower housing (1), and is collected and reused by the lower housing (1). By moving the motor shaft (28) and the conductor rotor (30) to the left and gradually increasing the meshing area of the permanent magnet rotor (29), the rotational speed is gradually increased to achieve torque transmission. The rotational speed of the load shaft (27) is adjusted. During this process, the rotational seal at the load shaft end is achieved by using the seal ring pressing plate A (21), the fluororubber seal ring A (22), and the silicone rubber seal ring A (23); the rotational and movable seal at the motor shaft end is achieved by using the seal ring pressing plate B (24), the fluororubber seal ring B (25), and the silicone rubber seal ring B (26).

Any modifications made on the basis of the technical solution according to the technical idea proposed by the present invention fall within the protection scope of the present invention; the technologies not involved in the present invention can be realized through the existing technologies.
