泵在工业中被广泛应用,其中二次侧压力是随负荷的变化而变化的。以前是用阀来进行控制,但响应时间慢,难于进行最佳控制。 采用频率变换的方法控制连接泵的感应电动机,即可解决这个问题。 首先,由压力传感器接收泵的二次侧压力,并将其信号输入压力调节器,调节器的输出电流通过予置放大器放大、变换,再经过远距离操作器输入频率控制器,然后进行频率变换,采
Pumps are widely used in industry, where the secondary pressure changes with load. Valve was used to control, but the response time is slow, it is difficult to control the best. The use of frequency conversion method to control the pump connected to the induction motor, you can solve this problem. First, the pressure sensor receives the pressure on the secondary side of the pump and inputs its signal to the pressure regulator. The output current of the regulator is amplified by a preamplifier, converted, and then input to the frequency controller via a remote operator, followed by frequency conversion , Mining
