1 冷冻机的油泵电机应由两路电源供电在大型高级民用建筑和工矿企业里,FLZ—500型、FLZ—1OOOA型离心式冷冻机组的应用日益增加。这一类别的冷冻机组的使用说明书,十分明确地阐述了油泵电机的技术要求:油泵电机,380V,4P,1.1～1.5kW,其正常的工作过程是开动于主电机之前而停止于主电机之后,主机在运转时,起润滑与冷却作用的油始终不间断。但当前冷冻站配电设计中,油泵电机往往与主电机由同一路电源供
1 The oil pump motor of the refrigerator should be powered by two power sources. In large-scale civil buildings and industrial and mining enterprises, the application of FLZ-500 and FLZ-1OOOA centrifugal refrigeration units is increasing. The operating instructions for this type of refrigeration unit clearly state the technical requirements of the oil pump motor: the oil pump motor, 380V, 4P, 1.1 to 1.5 kW. The normal working process is to start after the main motor and stop after the main motor. When the main machine is in operation, the oil that acts as a lubricant and cooling is always uninterrupted. However, in the current refrigeration station power distribution design, the pump motor is often provided with the same power supply as the main motor.
