A study of the appropriate air chamber volume of the hydraulic ram pump

Abstract

This research project aims to investigate the possibilities of boosting the pumping rate of hydraulic ram pumps. By developing a pump based on a National Science and Technology Development Agency prototype. Then adjust the air chamber capacity between 4,052 (H0.50) and 7,293 (H0.90) cubic cm. The entry water tank level is 2.15 meters high, while the end water tank level is 4.45 meters high. The study found that the optimal air chamber capacity was 5,672 cubic cm (H0.70), with an average pumping rate of 16.32 liters per minute (77 per cent efficiency), which was higher than the average pumping rate of NSTDA pump approximately 2.39 times. It has been shown that increasing the volume of the air chamber appropriately can increase the pumping rate of the hydraulic ram pump.
