Abstract
For the past two decades, Water Jet Technology has been studied and developed in order to facilitate the mechanical and material improvement of high pressure pumps. In particular, for nearly ten years, the practical use of this technology has been widely expanded from civil engineering to medical tools. YBM has been developing and distributing mud pumps together with boring/drilling machines for mine drilling, ground water development and civil construction. The YBM high pressure triplex plunger pump (Jet Pump), developed according to accumulated technology, is utilized for jet cutter piling and jet grouting jobs in civil construction works, fracturing and water circulation works in the test of Hot Dry Rock (HDR) electric power generation systems, and the Oyster-shell Crushing and Tilling Systems used in fishery farms. Several example of Jet Pump utilization are introduced in this technical note.
