Description

Technical Field

[0001] This utility model relates to the field of pumping equipment technology, specifically to a hydrogeological pumping test device. Background Technology

[0002] Hydrogeological pumping tests are an important part of groundwater science research. They aim to understand the distribution, movement patterns, recharge sources, and hydraulic connections of groundwater with other water bodies by extracting and observing its dynamic changes. During pumping tests, impurities are present in the extracted water, necessitating filtration devices. For example, a hydrogeological pumping test device with patent application number CN202322255779.9 includes an automatic cleaning mechanism for the filter screen. However, this device only uses a filter screen for filtration, resulting in ineffective filtration and the continued presence of impurities in the test water, which affects the test results.
