以往船用的制冷压缩机一般都是陆用替代的,存在了一些问题。如今,上海冷气机厂五分厂引进日本大金工业公司的生产技术和工艺手段,已生产了2HC-58(2)L、3HC58(2)LB 等机型的半封闭制冷压缩机。适合造船工业中低温风冷机、高背压冷藏与冷冻的需要,这种设备具有较狭窄的外形和两种通用的电制(50Hz—380～415V,60Hz—400～440V)等优点。据了解,该设
In the past, marine refrigeration compressors were generally replaced by land, with some problems. Now, the fifth branch of Shanghai Air-Conditioner Factory introduced the production technology and technological means of Japan Daikin Industries Co., Ltd. and has already produced semi-enclosed refrigeration compressors of 2HC-58 (2) L, 3HC58 (2) LB and other models. Suitable for medium and low temperature air-cooled machines in shipbuilding industry, high back pressure refrigerating and freezing needs. This kind of equipment has the advantages of narrower appearance and two general electric systems (50Hz-380-415V, 60Hz-400- 440V). It is understood that the set
