Based on the market demand of the flushing fluid centrifuge that is small, light, easy to move in medium-shallow hole of the small-diameter geological drilling, TGLW220×660 flushing fluid centrifuge has been independently developed. It has the characteristics of small volume, light weight, simple and compact structure, easy installation and disassembly, flexible, good treatment effect, low energy consumption and easy to move, etc. The whole structure, working principle, performance characteristics and of TGLW220×660 flushing fluid centrifuge are mainly introduced in this paper.
