【摘要】 针对抽油机工作时电动机负载不均衡的生产实际问题,研制一种抽油机专用电流表。电流表以89C55单片机为核心,实时测得抽油机工作时的电流、电压、功率等,从而计算出电流平衡比,对抽油机平衡块合理配备,提高抽油机工作效率,对最大限度减少电网干扰及节约能源有一定意义。更多还原

【Abstract】 In order to solve the unbalance of the oil-pump electric motor load, we study an oil-pump special amperemeter. This meter based on 89c55 microprocessor can actually measure ampere, voltage and power of the oil-pump stroke. According to these ampere data, we can calculate the balance ratio of the oil-pump. So we can use the balance ratio to outfit the weight of the electromotor to improve the system efficiency of the oil-pump, to deduce the burden of the power and to save energy source as possible as we can.更多还原
