现在我国肉类联合加工企业中运行着一批大型的AS170系列氨压缩机,由于氨压缩机的热负荷是一变景,而成套供货的AS170型氨压缩机,其电动机多是按空调与标准工况配套的,而这种氨压缩机在肉类联合加工企业中往往用于双级制冷机组中的低压级,由于压缩比小,不可避免地会出现较重的大马拉小车而浪费用电的情况,例如我厂一台低压级用的8AS170型氨压缩机,根据计算轴功率有95千瓦即够,而成套供货的动力却是功率为190千瓦的火型电动机(J3—400M1—8型△形接线),由于配套
Now China’s meat processing enterprises in the operation of a number of large-scale AS170 series ammonia compressor, ammonia compressor heat load is a scene, and complete sets of supply AS170 ammonia compressor, the motor is mostly by air-conditioning and Standard operating conditions, and this ammonia compressor in the meat processing enterprises are often used in the low-pressure stage of the two-stage refrigeration unit, due to the small compression ratio, inevitably there will be a serious waste of large carriages and waste Electricity situation, for example, I plant a low-pressure grade 8AS170-type ammonia compressor, according to the calculated shaft power of 95 kW that is enough, but the power supply package is a 190 kW power-type fire motor (J3-400M1 -8 △ -shaped wiring), due to supporting
