This paper presents the experiment results of the cycle work and overall performance of a new design of delivery valve in hydraulic ram. A hydraulic ram comprises of two non-return valves. They are well known as waste and delivery valves. Both mechanism propagate water hammer in cycle work of the hydraulic ram. In early designs, the water flow phenomenon occurring in the hydraulic ram operating process must be fully recognized for further analysis. | Investigation of tilt angled delivery valve in hydraulic ram experiment results International Journal of Mechanical Engineering and Technology IJMET Volume 11 Issue 2 February 2020 pp. 117-129 Article ID IJMET_11_02_011 Available online at http ijmet JType IJMET amp VType 11 amp IType 2 ISSN Print 0976-6340 and ISSN Online 0976-6359 IAEME Publication INVESTIGATION OF TILT-ANGLED DELIVERY VALVE IN HYDRAULIC RAM EXPERIMENT RESULTS M.

A hydraulic ram comprises of two non-return valves. They are well known as waste and delivery valves. Both mechanism propagate water hammer in cycle work of the hydraulic ram. In early designs the water flow phenomenon occurring in the hydraulic ram operating process must be fully recognized for further analysis. Therefore a transparent acrylic material of a hydraulic ram model was utilized to simulate the flow pattern within the hydraulic ram. In this study the water flow phenomenon was visualized experimentally using dyes injection method. Then videos and pictures recorded using slow motion video camera for investigating the hydraulic ram working cycle. The transparent hydraulic ram model was the first time introduced. The results show that the delivery valve with tilt-angled of 60 was the best design to produce the optimal performance of the pump system. The most stagnation point of the flow directed through the delivery valve orifice. The total efficiency of the hydraulic ram .
