Avaliação das condições operacionais do sistema de bombeamento, estudo de caso: Entreposto Auto Maputo (oficina GM)

Abstract

Water is one of the most important natural resources in human existence, supplying the basic needs and also in the development of economic activities, in order to ensure its availability are developed supply systems and especially pumping systems pumping systems that have the function of pumping the water, overcoming unevenness to the place of use. Ensuring that this system is able to adequately perform its mission is the main objective of good technical management and the periodic evaluation of performance assists in the prognosis of the condition of the system. In view of this, this research aimed to conduct an assessment of the conditions operational conditions and determine the actions necessary to improve the efficiency of the pumping system in use at Entreposto Auto-Maputo (GM Workshop). To this end, visits were made, technical information about the equipment and data of daily operations. With the data a detailed sensorial inspection was carried out with the purpose of diagnosing potential failures and the analysis of performance indicators, focused on evaluating three performance indicators of the IWA (International Water Association). From this This way it was identified several flaws in the operation of the pumping system elements mainly in the motor-pump sets and performing the analysis of performance indicators performance indicators concluded that the sets motor-pump existing in the pumping station operate with some precariousness and with unsatisfactory levels of energy efficiency.
