secondly, in the process of pressure supply, the left end of the rotor (192) drives the circular column (34) to rotate, the circular column (34) can drive a plurality of sealing plates (35) on the surface to rotate, meanwhile, the sealing plates (35) are contacted with the air pressure sleeve (32) and rotate, the first transmission wheel (28) and the second transmission wheel (30) pass through the transmission belt (31), so that the first transmission wheel (28) can drive the rotating shaft (272) to rotate on the bearing (273), air flow generated by a plurality of fan blades (275) on the rotating shaft (272) flows into the air pressure sleeve (32) through the vertical pipe, and when the sealing plates (35) rotate through the vertical pipe, the sealing plates (35) rotate the entering air flow to the position of the air outlet pipe (33), under the action of centrifugal rotation, the air flow enters the inside of the pressure supply cavity (26) from the air outlet pipe (33), so that the air pressure inside the pressure supply cavity (26) is increased, thus, the air pressure in the pressure supply cavity (26) enters the water storage tank (4) from the air pressure pipe (18), so that the cooling water in the water storage tank (4) and the annular water cooling cavity (3) can be raised by the air pressure liquid level;

a third step; along with the rising of the liquid level of the cooling water, the cooling water enters the annular cooling mechanism at the moment, the water inlet shape sleeve (10) is arranged in the fixed sleeve (9) of the annular cooling mechanism, after the cooling water enters the water inlet shape sleeve (10), the cooling water moves downwards to the annular water distribution plate (13) from a plurality of first vertical hollow bars (12) communicated in the water inlet shape sleeve (10) and is distributed by the annular water distribution plate (13), the cooling water firstly enters the arc-shaped groove (132), so that the cooling water gathered in the arc-shaped groove (132) gathers on the water storage plate (133) and flows downwards on the water storage plate (133) from a plurality of water discharge grooves (134) to uniformly distribute the cooling water on the cold collection ring (14) and gather in the arc-shaped water storage sponge, the rotating output shaft (8) can be cooled, and the situation that the joint is subjected to high temperature due to the over-fast rotation of the output shaft (8) is avoided, thereby ensuring the sealing performance of the motor;

the fourth step; after cooling water enters the first copper pipe (17) and the second copper pipe (16) respectively and enters the water inlet pipe orifice (203) from the first copper pipe (17) and the second copper pipe (16), due to the round block (205) arranged on the water inlet pipe orifice (203), the injected water can be dispersed into dispersed water flow under the blocking of the round block (205), so that the water flow enters the partition plate (206) from the first arc water tank (2041) and the second arc water tank (2042), due to the blocking of the partition plate (206), the entering cooling water surrounds the guide plate (207), under the diversion of the guide plate (207), the guide plate (207) enables the cooling water to circulate along the annular circulation cavity (210), so that the cooling water is contacted with the blades (211) in the circulating process of the annular circulation cavity (210), and the blades (211) can drive the rotating ring (212) to rotate in the hollow ring sleeve (201), the arc-shaped block (213) and the rotating ring (212) can be contacted with cooling water to dissipate heat of the motor assembly, and the situation of internal expansion is reduced, while the circulating cooling liquid of the annular circulating cavity (210) partially enters the second water outlet hole (2122) and enters the first water outlet hole (2124) from the second water outlet hole (2122), at the moment, the cooling water is in the arc-shaped block (213), due to the arrangement of the heat dissipation circular pipe (214), hot air in the motor assembly (19) is contacted with the heat dissipation circular pipe (214), so that the heat dissipation circular pipe (214) generates high temperature, when the cooling water is contacted with the part of the heat dissipation circular pipe (214) positioned in the arc-shaped block (213), the heat can be rapidly exchanged inside, when the cooling water flows, the cooling water can be contacted with the heat dissipation fins (216) on the fixing ring (215), so that the heat dissipation fins (216) can rotate the fixing ring (215), further, the heat dissipation speed can be improved;

the fifth step; when cooling water passes through in the return water cooling device (24), because heat dissipation flabellum (23) rotate, heat dissipation flabellum (23) make return water cooling device (24) airflow quick flow like this, the quick flow of cooling water of first circulation circle (241), second circulation circle (242), third circulation circle (243) and fourth circulation circle (244) in return water cooling device (24) like this, and then cool down the processing to the cooling water, the cooling water can flow back into in water storage tank (4).
