Title: Pressurization method for fluid
Inventor: HUANGFU HUANYU
IPC: F03G3/00
Filed: 2019-10-13
Abstract: Disclosed is a pressurization method for a fluid. In the method, a fluid is accelerated and then decelerated. During deceleration, no deceleration kinetic energy of the fluid is recycled. Before the acceleration of the fluid, a ratio range of a deceleration kinetic energy loss preset value of the fluid is pre-determined according to a preset proportional relationship between the deceleration kinetic energy loss preset value of the fluid and an obtained preset value of pressure energy of the fluid, and the fluid accelerated mass able to satisfy a corresponding kinetic energy loss condition under a corresponding acceleration condition is pre-determined according to the ratio range. In the process of acceleration or deceleration of the fluid, the pressure intensity of the fluid is adjusted from pressure intensity I to pressure intensity II according to a speed variation rate and a motion state of the fluid. If the pressure intensity I is less than the pressure intensity II, the pressure energy of the fluid under the action of the pressure intensity II is acquired. If the pressure intensity I is greater than the pressure intensity II, the pressure intensity recovers from the pressure intensity II to the pressure intensity I, and then the pressure energy under the action of the pressure intensity I is acquired. The pressurization method prevents the acceleration energy loss of the fluid from exceeding a preset value by means of pre-determining the fluid accelerated mass, and can be widely applied to the fields of power, electricity and industrial production.
