Abstract Predicting and optimizing the mechanical performance of the helically wound nylon-reinforced rubber fertilizer hose (HWNR hose) is crucial for enhancing the performance of hose pumps. This study aims to enhance the service life of HWNR hoses and the efficiency of liquid fertilizer transport. First. a finite element simulation model and a mathematical model were established to... https://www.chiggate.com/satisfyer-pro-penguin-next-generation-on-sale/
