Fluorine plastic centrifugal pump working principle of introduction

Fluorine plastic centrifugal pump can be used to transport the concentration of sulfuric acid, hydrochloric acid, nitric acid, organic solvents and other corrosive media, is currently one of the most advanced corrosion-resistant equipment. So what is the working principle of the pump? With such questions, the following is about the working principle of the fluorine plastic centrifugal pump. Fluoroplastic centrifugal pump works When the fluorine plastic centrifugal pump starts, the pump shaft driven impeller together for high-speed rotary motion, forcing pre-filling in the liquid between the blades rotate, under the action of inertial centrifugal force, the liquid from the impeller center to the outer diameter To exercise. Liquid flows through the impeller in the process of gaining energy, static pressure can increase the flow rate increases. When the liquid leaves the impeller and enters the pump casing, it will decelerate due to the gradual enlargement of the flow passage in the shell. Some of the kinetic energy will be converted into static pressure energy and flow into the discharge pipe in the tangential direction finally. Therefore, the snail-shaped pump housing is not only a collection of components from the impeller out of the liquid, but also a transformable device. When the liquid thrown from the center of the impeller to the periphery at the same time, the center of the impeller to form a low pressure zone, the tank surface and the impeller center of the total potential difference under the action of the liquid was sucked into the impeller center. Depending on the continuous operation of the impeller, the liquid is continuously aspirated and discharged. The mechanical energy obtained by the liquid in the centrifugal pump ultimately appears as an increase in static pressure energy. It should be emphasized that if the pump housing is filled with liquid being delivered prior to start-up of the centrifugal pump, due to low air density the centrifugal force generated by the rotation of the impeller is small and the central area of ​​the impeller is insufficient to create a low pressure liquid sucked into the sump , So although the start of the centrifugal pump can not deliver liquid. This shows that there is no self-suction centrifugal pump capacity, this phenomenon is called gas tie. Suction piping The one-way bottom valve is installed to prevent the liquid poured into the pump casing from flowing out of the casing before starting. Air from the suction pipe into the pump casing will cause air binding.
