Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand
that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to
achieve more efficient operations.
Wind is a form of solar energy.
Winds are caused by the uneven heating
of the atmosphere by the sun, the
irregularities of the earth’s surface, and rotation of the earth. Wind Turbines
convert the kinetic energy in wind into
mechanical power.
Energy is the worldwide addiction of the human race. We can’t live without it, and no matter how much we try to conserve
it, our appetite is insatiable.
This three-part series on motor management best practices focuses on the importance of instituting a motor management plan as a necessity in effectively administering the electric motors in a facility. The goal of a motor management plan is to take advantage of opportunities for energy savings and increased productivity using energy efficient, reliable
motors such as NEMA Premium efficiency motors, herein referred to as “premium efficiency” motors.
Energy costs and downtime can be greatly reduced by instituting a motor management plan. Part II of this three-part series specifically addresses the establishment of a motor failure policy and the development
of purchasing specifications. Part I addressed the general aspects
of a motor management plan, including the first steps of creating a motor inventory and guidelines for motor repair and replacement. Part III will examine motor repair specifications
as well as preventive and predictive maintenance.
The Department of Energy estimates that 4 million megawatts of potential
power—four times the amount all U.S. power plants combined currently produce—exists in offshore wind energy. Construction of America’s first offshore wind turbines began in July. The wind farm, which is being constructed off the coast of Block Island, RI, will consist of five turbines. Together, they will produce 30 MW.
