AI Technical Summary
In existing inverted water pumps, the pressure regulating diaphragm structure is difficult to install and function effectively, resulting in difficulties in regulating the internal pressure of the motor. Furthermore, the oil filling scheme inside the motor cavity has heat dissipation and sealing problems.
Design a pump and motor structure that uses a semi-oil-filled method, with the cooling medium height higher than the rotor. Combined with a reasonable oil filling amount and oil chamber design, the minimum oil filling amount and oil chamber volume are determined by calculation to ensure that the cooling medium inside the motor can cover the rotor and avoid mechanical seal failure caused by excessive pressure difference.
It achieves effective regulation of the internal pressure of the motor, avoids the problem of the pressure regulating diaphragm not being compatible, ensures the balance between motor temperature rise and structural strength, optimizes the structural dimensions, avoids redundant design, and makes the water pump lightweight.
