Screw compressor unit:
Meet the design concept of API-619.
Compressor shell - cast steel (normal temperature and low temperature; the lowest temperature can reach - 100℃)
Rotor - forged steel
Bearing - hydraulic type, no point or line contact, which will greatly prolong the compressor usage life of the compressor and ensure 5 years of continuous operation.
Shaft seal - can be sealed by dry gas or by pressurized oil
Flushing scheme - API PLAN 72, or API PLAN 53.
Oil circuit system - dual line design, can switch oil coolers, oil filters, oil pumps and essential oil filters online. The material can be designed as all stainless steel.
Control system - customized design, two-out-of-two, two-out-of-three, or CPU redundancy. The system can be composed of PLC, or directly controlled by user’s DCS.
