摘要:

Industrial energy management includes the fuel procurement, production, conservation, and efficient use of utilities such as steam, electricity, compressed air, and water. Steam is the underpinning utility and has the greatest economic impact. The efficient production and delivery of quality steam directly affects the cost of the other utilities as well as the manufacturing process.

摘要:

Energy costs to operate electric motors can be a significant part of an operating budget. For example, a recent survey of California water departments reveals energy costs for pumping and treating water may be 25 percent of operating costs. Strategies to reduce these costs include reducing the operating time (turning off unnecessary equipment), using controls to match pump output with demand, optimizing motor systems, and installing energy-efficient motors.

摘要:

This article reviews and summarizes techniques for using or sharing signals from existing facility and utility meters for the purpose of verifying energy savings from industrial, institutional, and large commercial energy conservation projects. Techniques for sharing or using signals from existing electric, natural gas, fuel oil, steam, steam condensate, boiler feedwater, hot water, and chilled water meters will be described. The techniques and experiences reported in this article are based on the results of the actual in-field installation of energy monitoring equipment in several hundred sites at various locations throughout the United States.

摘要:

Injection molding is a common method of plastic processing in which thermoplastic materials can be molded into arbitrary complex shapes. Most injection molding machines use complicated hydraulic systems to perform the necessary work of the process. Hydraulic system flow and pressure requirements vary throughout the cycle and in many cases, excess fluid that is not required by the process is throttled back to the reservoir, wasting motor energy and producing additional thermal load on the cooling system. Variable speed drives can be used to allow injection molding machine hydraulic systems to vary the amount of fluid being pumped and thus reduce the amount of fluid that is throttled reducing the amount of wasted energy. This article discusses injection molding machine processes and develops a protocol for assessing the efficacy of variable speed drive retrofits for hydraulic injection molding machines.
