全封閉旋轉(zhuǎn)曲柄式自動管道取樣機，是總結(jié)礦山多種取樣機的特點而研制成功的新型自動管道取樣設(shè)備，具有結(jié)構(gòu)新穎、設(shè)計合理、性能可靠、安裝簡單、操作方便等優(yōu)點。該取樣機順管道安裝，不需要任何高差，對礦漿無任何落差損失。取樣勺結(jié)構(gòu)獨特，垂直于礦漿流向取樣，取樣準(zhǔn)確、代表性強；取樣時間在5-50分鐘區(qū)間內(nèi)可隨時任意設(shè)定和改變。電氣部分采用了光電新技術(shù)，設(shè)有完善的保護電路，控制簡便，動作靈敏，安全可靠。該機是替代老式取樣機的理想設(shè)備。

Automatic pipe sampler of fully enclosed turning crank,which combines the advantages of many different sampler used in mines.This automatic pipe sampler with fully enclosed turning crank has such characteristics as new structure,reasonable design, reliable performance,,simple,simple installation and easy operation etc.This sampler is mounted along the pipeline,and there is no need for elevation difference.Thus no pressure head lose is caused.Because of the special structure of the sampling spoon and sampling perpendiculal to the slurry flow,the sampling is accurate and representative.Sampling time is adjustable between 5 minuets to 50 minutes.New optoelectronic technology is applied to the electrical part and complete safety protection circuit is prepared and so its control is rather simple,action senaible and safety reliable.It is an ideal equipment to replace the old sampler.
