本装置中大部分采用P——MOS集成电路,既降低设备制作成本,又提高运行的可靠性。对生产中所添加的三种药(黄药、硫化钠、二号油)的控制、累计,采用共同振荡源分频的方法,使线路简单、合理。振荡器采用“双T”选频网络,频率较稳定,因此可采用电磁计数器对 Most of the devices using P - MOS integrated circuits, both to reduce equipment production costs, but also improve the reliability of operation. The production of the three added drugs (xanthate, sodium sulfide, the second oil) control, total, using a common oscillator source frequency, the line is simple and reasonable. Oscillator using “double T” frequency selection network, the frequency is more stable, so the electromagnetic counter can be used
