我厂在生产车间大批使用气动量仪进行工件测量。气动量仪用气由空压站供给。以前由于没有过滤,气中含有大量水份和杂质,势必进入仪器,严重影响气动量仪的正常使用和维护。我们针对上述情况,自己动手,利用废旧物品,将空压站供气在通往气动量仪前经过三级过滤。实行三级过滤后,计量人员还需到车间放水,我们又动脑筋,想办法,在过滤风包放水管上安 I plant a large number of production workshop in the use of pneumatic measuring instrument for workpiece measurement. Pneumatic gauge gas from the air supply station. In the past because there is no filtration, the gas contains a lot of water and impurities, is bound to enter the instrument, seriously affect the normal use and maintenance of pneumatic measuring instrument. In response to these circumstances, we do it ourselves and use waste materials to filter air at the air compressor station before passing to the gas meter. After the implementation of three filters, the measurement staff need to go to the workshop water, we have brains, think of a way, in the wind filter package on the security
