YGZH 潜水泵电机技术要求

1. Electric motors shall comply with the requirements of this standard and be manufactured in accordance with approved drawings and technical documents through prescribed procedures.

2. Under the following usage conditions The electric motor should be able to operate continuously at rated capacity.

3. Electric motors are completely submerged in water Based on the extended end face of the motor shaft, its underwater depth should not exceed 5 nu

4. The maximum ambient water temperature varies with the seasons But the ambient water temperature should not exceed+40 degrees Celsius.

Note:; If the electric motor is used under the condition that the water temperature is higher than 40 €, it should comply with the provisions of UcGB 755-2000.

5. The electric motor is of the wet heat type Has moisture resistance Anti fog The function of preventing salt spray

6. The deviation of power supply voltage and frequency from the rated value during the operation of the motor shall comply with the provisions of GB 755-2000.

Note: Efficiency is measured indirectly. When determining the total loss of the motor, the resistance loss of the winding should be converted to the value at the B-level insulation reference operating temperature, and the stray loss should be calculated at 0.5% of the rated input power.
