A New Hydraulic Pressure Intensifier Using Oil Hammer

Abstract

An oil hammer generates a greater pressure than that supplied to a pipeline, and sometimes causes equipment breakdown. The author intends to actively utilize this pressure rise. A new type of pressure intensifier is proposed, which converts oil pressure into a value more than six times higher, by means of an oil hammer. The intensifier has advantages in simple structure and in easy control since it is controllable by switching only one solenoid operated valve. A theoretical analysis describing the performance and operation of this design is developed. Results of experimental work on this design are then compared with theoretical results.
