Long axis pump is a type of centrifugal pump equipment, from the perspective of the centrifugal pump, it is a long axis pump submersible pump on the basis of further changes, so its performance is superior to submerged pump. With the use of long-axis pumps continue to strengthen, long-axis pump works for users is the most basic and most important information. Next, we will analyze the working principle of long axis pump. Working principle of long-axis pump Working principle of long-axis pump Long-axis pump casing filled with liquid being transported, start, the impeller driven by the shaft at high speed rotation, the liquid between the blades must also rotate with. Under the action of centrifugal force, liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller to enter the scroll casing at a high speed. In the volute, the liquid due to the gradual expansion of the slowing down, but also part of the kinetic energy into static pressure, and finally to a higher pressure into the discharge pipe, to the required place. When the liquid flows from the impeller center to the outer edge, a certain vacuum is formed in the center of the impeller. Since the pressure above the liquid level in the sump is greater than the pressure at the inlet of the pump, the liquid is continuously pressed into the impeller. Visible, as long as the impeller constantly rotating, the liquid will be continuously inhaled and discharged. When the pump housing air, due to the density of the air density is much smaller than the liquid generated less centrifugal force. As a result, the pressure difference above the level of the sump and the suction of the pump is insufficient to press the liquid in the sump into the pump, i.e., the pump is not self-priming, so that the pump can not deliver liquid. In order to fill the pump with liquid, At the bottom of the tube, a bottom valve with strainer is installed. The bottom valve is the reverse valve. The function of the strainer is to prevent the solid matter from entering the pump to damage the impeller or hinder the normal operation of the pump. Through the analysis of the working principle of the long axis pump, we have got a better understanding of the long axis pump and other equipment far away from us. As long shaft pumps play an increasingly important role in many industries, the study of long shaft pumps will go one step further and the working principle of long shaft pumps will be better optimized.
Plastic additives are the compounds which must be added to improve its processing performance or improve resin performance when molding. Thus, plastic additives play the particularly important position in the plastic molding process.
