日本荏原制作所建成了17DJ 系列开式离心式制冷机(见表1)。考虑到夏季供电紧张和利用流程的废热,该系列制冷机可以采用汽轮机、防爆电动机、柴油机和煤气发动机等多种原动机驱动。其制冷剂为 R11。离心式制冷机由可调进气导叶、蜗壳、压缩机壳体和密封装置等构成。进气导叶径向布置,可以进行高效率的制冷量自动调节。在蜗壳中装有开式轻合金制叶轮,可根据需要设计在最高效率下运行。压缩机壳体中装有增速齿轮箱与四个轴承。密封装置为石墨环端面密
Japan Ebara factory built 17DJ series open centrifugal chiller (see Table 1). Taking into account the summer power shortage and waste heat utilization process, this series of refrigerators can be used turbine, explosion-proof electric motors, diesel engines and gas engines and other prime mover drive. The refrigerant is R11. Centrifugal chiller is made up of adjustable inlet vane, volute, compressor housing and sealing device. Radial guide vanes arranged radially, you can efficiently adjust the cooling capacity. In the volute equipped with open light alloy impeller, according to the needs of the design to run at the highest efficiency. The compressor housing is equipped with a speed-increasing gearbox and four bearings. The sealing device is graphite ring end face dense
