Modelling of Polymer Suction Tube through Simulations

Abstract

<div class="section abstract"><div class="htmlview paragraph">The oil is picked up from the oil sump and transferred to the pump housing via a suction tube at the desired rate. A strainer is fitted to the end of the suction tube to filter out any dust or debris that may be present. Steel tubes and wire mesh strainers are used to make the current suction tube. Suction tube design shouldn't have an excessively long inlet suction that would make the suction tube's pressure insufficient to suck the oil from sump. Additionally, the pump's suction side air leak or low temperature-induced low oil viscosity prevents the pump from priming. This paper will examine suction tube design analysis and compared the development of steel and polymer suction tube concepts. The lightweight polymer suction tube with respect to fluid dynamics aspects is compared with conventional wire mesh. Extreme temperature analysis of polymer suction tubes will be compared to baseline steel tubes for suction flow, the impact of mesh area, pressure drop, and temperature parameters, and findings will be presented. The flow performance of polymer suction tubes was found to be substantially above that of steel wire mesh suction tubes. Due to the decreased opening area of an all-polymer suction tube, the average pressure drop is larger, and pressure decreases in the suction tube have an impact on the pump's filling speed. Compared to steel suction tubes, polymer suction tubes are lighter and cheaper, easier to manufacture, need fewer parts, and have higher reliability.</div></div>
