低温螺杆式冷冻机:The low temperature screw refrigerating machine 性能特点 ? 采用进口高效较新一代经济器型半封闭双螺杆压缩机,能效比较高,运行稳定,寿命长; ? 独立制冷系统设计,多机头机组相互独立,互不干涉,运行可靠; ? 压缩机在较小负荷(25%),通过星三角降压启动,较大程度减小机组启动时对电网的冲击; ? 柔性化的容量调节,可使机组在25%-**之间运行,同时若机组长时间运行在50%区间,机组通过内部程序将压缩机加载到**运行,可有效减少压缩机轴承的磨损,加大压缩机的使用寿命。 ? 采用高精度大屏幕触摸屏,配合工业级PLC自动控制系统,同时通过标准接口,远程用户和控制室可实现多种控制功能; ? 选用国际**品牌的膨胀阀、单向阀、过滤芯等制冷配件,保证机组在宽广的使用范围内可靠的运行。 The performance characteristics of ? Imported efficient generation of new economic shape semi-enclosed twin-screw compressor, can effect comparing is extremely high, stable operation, long service life; ? Independent refrigeration system design, more head sets are independent of each other, non-interference in each other, and reliable operation; ? Compressor in minimum load (25%), through the star triangle step-down start, minimize the impact on the grid unit startup; ? Flexible capacity adjustment, can make the unit running between 25% and **, but if the long running unit in the 50% range, unit through internal procedure will compressor to run load to **, and can effectively reduce the compressor bearing wear, increase the service life of the compressor. ? Big screen monitor with high precision, with industrial PLC automatic control system, at the same time through a standard interface, remote users and control room can realize a variety of control functions; ? With international famous brand expansion valve, check valve, filter, such as refrigeration fittings, guarantee in the use of the wide range of reliable operation。
