Avaliação da eficiência energética em estações elevatórias prediais
(Universidade Tecnológica Federal do ParanáToledoBrasilEngenharia CivilUTFPR, 2018-06-12)
The use of a water pumps in lifting stations consumes electric power to carry out the water to superior levels. In order to evaluate the consumption of this equipment, there were created some indexes capable of measuring ...
Comparison of water pumping between pump driven by wind mill and electric motor into Brazil
(2014-04-01)
The proposed work consists in the comparison of the application of two systems for the pumping of water. With a pump drive by electric motor and the other by wind mill, in order to demonstrate the efficiency and pay-back ...
Water purification system using a heat pump
(Pergamon-elsevier Science LtdOxfordInglaterra, 2011)
An eco-friendly method for analysis of sulfonamides in water samples using a multi-pumping system
(2016-08-05)
A new methodology for determination of sulfonamides (sulfaquinoxaline, sulfathiazole, and sulfadimethoxine) in water samples was developed by coupling an automated multi-pumping flow system (MPFS) with a liquid waveguide ...
Estudo de uma máquina de fluido tipo helicoidal para bombeamento de água de rio
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2021-08-16)
Worldwide, many farmers use irrigation systems for their crops. They usually use highpower centrifugal or axial pumps powered by electrical energy or combustion engines. This technique provides increased productivity, in ...
Fabricação e estudo de bomba alternativa de dupla impulsão
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Mecânica, 2019-06-13)
A double-pumping piston pump was manufactured and tested
low-cost manual, for the operations of sending or raising water, without the use of
industrial pumps that require the presence of electric power, enabling them to ...
Integrated Model for Optimizing Strategic Overhaul Planning of Distributed Pump Stations
(ASCE-AMER SOC CIVIL ENGINEERS, 2011)
An important part of the lifecycle costs for pump stations are the support costs associated with energy and preventive maintenance of the pumps. Both cost terms are interrelated because a trade-off exists between maintaining ...
Thermal analysis of solar‑assisted heat pumps for swimming pool heating
(Springer, 2017-06)
The present work analyzes the technical feasibility of solar-assisted heat pumps for swimming pool heating in South Brazil. The methodology is based on computer simulations for four configurations of heating systems for ...
Análise hidroenergética de sistema de abastecimento de água: estudo de caso em sistema com captação subterrânea
(Universidade Tecnológica Federal do ParanáGuarapuavaBrasilEngenharia CivilUTFPR, 2021-08-24)
Water pumping stations consume on average 90% of the electricity of the entire water supply system (WSS). About 25% of electricity cost is due to the inefficiency of the pumping system. The reduction of this expense can ...
