Pump System in the Energy Manager Training Center at the Faculty of Mechanical Engineering University of Belgrade

Abstract

The Organization for the training of energy managers and authorized energy advisors or Training Organization (TO) was established on 20 November 2015 on the basis of a decision adopted by the Minister of Mining and Energy Republic of Serbia, which gave authorization to the University of Belgrade, Faculty of Mechanical Engineering to perform tasks relating to the training of energy managers (EM) and authorized energy advisors (EA). The establishment of the TO is one of the main results of two projects: “Introduction of Energy Management System in Energy Consumption Sectors in the Republic of Serbia” and “Project for Assistance of Enhancement of Energy Management System in Energy Consumption Sectors in the Republic of Serbia”, which the Ministry of Mining and Energy (MOME) conducted jointly with Japan International Cooperation Agency (JICA). In the scope of the second project JICA donated to MOME laboratory equipment and measuring instruments necessary for the practical training of EM and authorized EA, install equipment and make operational the Laboratory for practical training. The equipment was officially put to use on 11 October 2016. Center posses three plants: pump, air compressor and boiler units. Here is presented pump unit. In this paper are presented three exercises. First one is determination of the pump performance curve. Pump is tested, by manufacturer technical specifications, in accordance with standard ISO 9906:2012, grade 3B with broad tolerance. So experimental data obtained in this test rig should be comparable with the ones in pump catalogue. In the second exercise is demonstrated significant influence of the pipe diameter on the system hydraulic losses, as well as pump duty point. The third exercise demonstrates pumps savings for regulation by using inverter instead of valve on the pump pressure side. This pump system is flexible, so some other aspects of energy saving measures could be implemented.
