本文综述了深度增加时限制电潜泵使用的各种因素。它详细介绍了在参数上相关的两个限制因素:泵轴功率额定值和止推轴承承载能力。前者限制了压头和流量的乘积,后者则限制了压头。此文证实,经过电动机的流体温度增加值正比于压头,与流量无关,同时对泵和电动机的效率值非常敏感。本文同时阐明了与增加深度有关的流体温升对电动机传热系数的影响。 This article reviews various factors that limit the use of ESP when depth increases. It details two parameters that are relevant in terms of parameters: pump shaft power rating and thrust bearing capacity. The former limits the product of indenter and flow, the latter limits the indenter. This paper confirms that the increase in temperature of the fluid passing through the motor is proportional to the indenter and is independent of the flow and is very sensitive to the efficiency values ​​of the pump and the motor. This article also illustrates the effect of increasing fluid temperature on the heat transfer coefficient of the motor.
