一、引言: 一般情况下,潜油电泵系统工作在一恒定转速,潜油泵的排量是通过油嘴来人工调节。这样就必然增加管路损失,并且词节范围也不大。可是在某些特殊情况下,如油井参数不明确,或是油井在产液过程中。排量下降很快等等,就需要潜油电泵的排量、扬程可调。而在潜油电泵系统中加入变频装置,就可以满足这样的需求。通过变频器改变了电源的频率,电机的转速是随着频率正比变化的。而潜油泵的排量是与电机的转速成正比的,扬 First, the introduction: Under normal circumstances, the submersible pump system work at a constant speed, submersible pump displacement is manually adjusted through the nozzle. This will inevitably increase the pipeline loss, and the word range is not large. However, in some special cases, such as the well parameter is not clear, or the oil well in the liquid production process. Displacement quickly decline, etc., you need submersible pump displacement, head adjustable. In the submersible pump system to join the frequency device, you can meet this demand. Change the frequency of the power through the frequency converter, the rotational speed of the electrical machinery changes with the frequency proportionally. The submersible pump displacement is proportional to the motor speed, Yang
