Structure and principle: On the SD three feet -like ex-dennings hang the bag centrifuge to be suitable for profession the and so on chemical industry, food, drugs manufacture, environmental protection solid fluid separation. This series centrifuge structure reasonable, the separation process entire seal, is suitable the environment especially which in the explosion-proof, is easy to pollute, used has hung the bag ex-denning way, reduced the artificial ex-denning labor intensity, enhanced the work efficiency, the outer covering top head has been possible manual, the mobile two ways to open, has facilitated the user choice. Has provided the frequency conversion velocity modulation control system and the explosion-proof operation column, causes the user to be possible the long-distance control to be possible the scene operation. The product design manufacture conforms to the GMP standard requirement.Technical parameter:
