  • Vibration reduction in water pump motor with magnetically boosted Tuned Mass Damper - Case Study

    Problem description: A 75kW water pump motor experiences excessive vibration levels (up to 11mm/s RMS) due to the presence of a structural resonance in the mechanical supporting structure (see below). The frequency of this structural resonance lays in the operating range of the variable speed motor, leading to a significant vibrations amplification. The vibration measurements have been ...

  • Upgrading Water Injection Pumps

    Water injection pumps that are used in oil exploration typically face extreme abrasion, chemical attack, and cavitation erosion in their daily operation. The injected water is frequently loaded with abrasive particles, such as quartz sand, which quickly erode conventional pump surfaces. Sulzer’s service teams offer solutions to increase the lifetime and the performance of water injection ...

  • Pumping water to decontaminate a karstic spring

    After being struck by lightning, an underground military fuel tank lost all its contents. After a few hours, petrol mixed with foam began to flow out of the nearby Forame spring, situated about 400 m away and at a height of 7.0 m lower than the bottom of the tank. The spring feeds the Giavera stream which, after about 1000 m enters the upper Veneto plain, flowing into the irrigation network. ...

  • Air as Clean as the Driven Snow

    While California is the most populated state in the nation, it is also home to some of America’s most natural and pristine wilderness and recreation areas. One such venue is the Snow Summit Ski Resort in Big Bear Lake.  Situated just over two hours from Los Angeles, Snow Summit is a fullservice winter resort that opened in 1952 and operates an average of 142 days a year. ...

  • Peristaltic pumps for moving filtration water

    The Eversburg sewage treatment plant is designed to serve 250,000 population equivalents and is one of three plants operated by the city of Osnabrück in northern Germany. But in 2005, its actual load was closer to 309,000 population equivalents (COD 80 mg/l), pushing the nitrogen input level above the plant's capabilities. To deal with this situation, engineer Peter Sikora organized a team ...

  • Signs You Need a New Water Pump

    Motor vehicles are built upon small parts doing big jobs. Consider your engine. It is likely the most important machine within your car, truck, or SUV, but it is not made up of one or two components, but thousands. Some engines have over 14,000 different parts to keep them operational. If just one of these parts, such as the water pump, fails, then the entire engine could grind to a halt. ...

  • Performances of photovoltaic water pumping systems: a case study

    This paper presents a mathematical motor-pump model for photovoltaic (PV) applications which allow us to contribute in the studies of PV pumping sizing. The modelled motor-pump characteristic is flow rate-power (Q, P). The model is established for centrifugal pump (CP) coupled to DC motor. The non-linear relation between flow rate and solar power has been obtained experimentally in a first step ...

  • Thermocline-driven desalination: the technology and its potential

    Seawater desalination technology is emerging as freshwater requirements are alarmingly increasing all over the world. Conventional technologies such as reverse osmosis and multistage flash evaporation have their limitations, such as chemical treatment and scaling. Low-Temperature Thermal Desalination (LTTD) is an attractive technology with vast potential. It makes use of the ocean temperature ...

  • Fuzzy maximum power extraction control for a photovoltaic water pumping system

    AC loads present a delicate matter for photovoltaic systems, and this is because of the photovoltaic panel's operating point, which moves randomly according to irradiance changes; in this case, almost of photovoltaic water pumping systems use a DC–DC converter to ensure either the maximum power extracted from PV panel or the load needs. For AC motor pumps, an inverter must follow this chopper. ...

  • Pumps as turbines (PATs) in water distribution networks affected by intermittent service

    A hydraulic model was developed in order to evaluate the potential energy recovery from the use of centrifugal pumps as turbines (PATs) in a water distribution network characterized by the presence of private tanks. The model integrates the Global Gradient Algorithm (GGA), with a pressure-driven model that permits a more realistic representation of the influence on the network behaviour of the ...

  • VFD for pumping systems

    Pumping systems account for nearly 20% of the world's electrical energy usage. In some process plants, the VFD for pumps and fans together account for between 50% and 80% of the total electricity used. Very rarely have I come across pumps operating with fully open discharge valves. The same is the case for fans with dampers. ...
