Configuration Features: 

 1. Precision mechanics the center of the bay, the motor of the permanent host. 

 2. Using high-elastic coupling, the machine running smoothly, elastomers, and long life. 

 3. Exhaust pipe using double bellows, oil temperature 125 C using a special high-pressure hose. 

 4. For the summer high temperatures, the use of large-scale plate heat exchanger. 

 Coupling of high-quality elastomer, the imbalance can be buffered running torque, and can be compensated. Elastomers involute arc design, effectively avoid the stress concentration, strengthen the body's buffering capacity of the elastic to make it more load capacity and high quality material to have good wear resistance and more effective absorption vibration during rotation so as to achieve noise-free results. 

 Reliability 

 Twin-screw host no wearing parts, under good conditions in the maintenance of trouble-free run time of up to 4-8 million hours.
