The use of hydraulic ram pump for increasing pump head‐technical feasibility

Abstract

The combined pump and hydraulic ram pump (HRP) was presented to evaluate the technical feasibility for increasing pump head. This method was used to demonstrate a possible low-cost alternative solution to supply water in remote areas. It illustrated the case where energy in rivers was not enough to drive HRP and a pump alone could not lift water to the required head. The HRP was connected in series with the pump. The experiment on the combined system operation was investigated. The system was working only at a certain range of flow rates for a power supply by the pump. Therefore, HRP was adjusted to pump water in the range that the waste valve was functioning. The combined system can operate at a low flow rate with a high head without extra energy and no overloading. It reveals that the more discharge head is required, the less flow can be lifted which results in a high number of valve beats per minute of the waste valve. Experimental determination of the optimal values for these parameters will make it possible to provide for a feasible design of HRP in the given pump. The optimal HRP will make it possible to ensure the required performance (delivery, head, efficiency) of the combined system.

The performance analysis of Hydraulic Ram Pump: Influence of specific parameters and validation with Comsol-Multiphysics

“…in the derived pipe with a power output of 1.273 KW and efficiency of 57.3% (Mohammed, 2007;Sutanto et al, 2022) obtained the best efficiency of 57.3% on the length of the 8 meter input pipe, Hence, using newly designed parameters in Table ( 4) in the proposed model is well justified. It must be worth mentioning that since more than 75% of the supply water is wasted at the waste valve to discharge water (Asvapoositkul, 2021) and hence ideal performance is rarely achieved (Young, 1995). The present proposal for proposed design allows further relevant investigations focusing on sophisticated assessment methods for hydrams for improvised performance and minimal waste valve losses as well.…”

“…3) As shown in the figure below, a waste valve and delivery valve are fitted, so its flap is initially open due to its self-weight. 4) To prevent the backflow of water due to forces in the pressure chamber, a delivery valve is placed on 5) A Pressure chamber whose function is to absorb the water hammer pressure Asvapoositkul et al (2021) that will occur in hydram is a PVC chamber fitted above the delivery valve with a nipple and a reducer, as shown in Figure 22. 6) The delivery pipe that connects the pump system is open to the atmosphere and is placed between the pressure chamber and the delivery valve with the help of the T joint.…”

Experimental and Numerical CFD Modelling of the Hydrodynamic Effects Induced by a Ram Pump Waste Valve

“…Specifically, the authors of [21,22] studied the effects of the waste valve on the performance of the hydram. Both experimental and numerical approaches were used to investigate this topic [25][26][27][28] for different specific purposes [29][30][31][32].…”

A Hydro-Powered Climate-Neutral Pump: Full Cycle Simulation and Performance Evaluation

“…Focused upon enhancing the resilience in varied operation conditions and to minimise the disruptive hammer noise and forces in HRP for a local installation to their residence. Several designs were produced, namely, the Oasis, Water Dragon and the Glockemann Pump [20,21]. The last of which awarded a Gold Medal at the Geneva 2002 International Exhibition [16] setting a high standard for its successor in the form of the Bunyip invented in 2006 by Bunyip Water Pumps, formally Porta's Affordable Pumps [8].…”

“…Upon review of several studies in the field, the primary indicator adopted for performance is the operational efficiency, calculating the ratio of power through the delivered volume (𝑃 ) relative to the total input quantity supplied (𝑃 ). The relationship derived below using the Head (𝐻) and Flow Rate (𝑞) ratio [21,22]. Ultimately, the value quantifies the capacity of the pump to overcome the elevated head and an opportunity to compare the system model and data against alternative pumps.…”
