Methodology for Analyzing the Actual Technical Condition of Downhole Pumping Equipment

The reducing in the pressure characteristic of submersible pump during operation occurs as a result combined action number reasons. Pumping equipment wears out due to waterjet destruction flow channels. characteristics pumps are captured at factory on special stands. At large group groundwater intakes, wells equipped with an automated control system that allows testing workplace and promptly making decision its replacement if is unacceptably reduced. actual H н = f ( Q ) can be plotted directly well sufficient degree accuracy. To determine wear pump, compared before installation time taking readings. article describes strapping scheme for measuring specific rate pump. purpose study derive dependency constructing flow-pressure develop method accounting operation, which predicting decrease productivity over time. An expression proposed describe any time, calculated from well. analysis produced by various manufacturers existing water intake underground presented. It confirmed intensity reduction depends duration given well, material impellers sand content pumped water.
