The attachment of inducer in front of main impeller is a powerful method to improve cavitation performance. In operating condition at partial flow rate and extremely low suction pressure. cavitation surge oscillation occurs and the stable operating range becomes narrower. It has been found from previous experimental study of authors that the cavitation surge oscillation with low frequ... https://thegreensjunglebeautyshops.shop/product-category/hair-perfume-mist/
