A modular prototype of a ram pump has been designed for data collection and ease of testing design alternatives. The pump has been installed in a hydraulic testing facility and initial testing has been done to determine ram pump efficiency at various drive flow rates and delivery heads. Ram pump design parameters, specifically check valve weight, check valve type, and air chamber size, need to be tested to determine their effects on ram pump efficiency. Using data collected from these experiments, our pump design and construction methods will be evaluated and optimized for implementation in an AguaClara plant. |
