在选厂技术监督中,采样是一种十分重要的过程,比制样、化验显得更为关键。通常要求采样机高差小,体积小,能够适应狭窄的空间,易安装维护,运转可靠、易维修;并且所采样品代表性强。 目前选厂大多使用机械往复式采样机。该机机械部分由丝杠、滑块、样勺、出样槽、出样管,防冒槽、防冒管组成。电气部分山电机、时间继电器、空气开关、交流接触器、热继电器、行程开关等组成。靠电机通过丝杠带动滑块上的样勺,来回移动进行采样。由于安装地点一般比较潮湿,而且常被跑冒滴漏的矿浆以及冲洗地面水所溅湿、
In the technical supervision of the mill, sampling is a very important process, than the sample preparation, laboratory testing is even more critical. Usually requires sampling height difference, small size, to adapt to the narrow space, easy to install and maintain, reliable operation, easy maintenance; and the sample representative of the strong. Most of the current selection of mechanical reciprocating sampling machine. The mechanical part of the machine by the screw, slider, sample spoon, a sample tank, a sample tube, anti-counterfeit slot, anti-take-off tube. Electric part of the mountain motor, time relay, air switch, AC contactor, thermal relay, trip switch and other components. Relying on the motor through the lead screw driven sample spoon, move back and forth for sampling. As the installation site is generally more humid, and often run by leaking slurry and ground water splashing wet,
