• Applying Steam Turbines For Pump Drives (.pdf)
  of the heat before the condensate returns to the boiler. Turbine arrangement is usually. straight non-condensing (no turbine extraction), and it is the most commonly used cycle for pump drive service. For pump. ratings of 3,500 hp or less, steam turbines are usually single-stage. Condensing Cycle...
• How Thermoelectric Modules Are Used in Heat Exchangers
  : thermoelectric modules are sandwiched between two surfaces. When DC current is applied, the thermoelectric modules "pump" heat from one surface to the other. The "cold side" of the heat exchanger is designed to maximize cooling within the customer's equipment. The "hot side" of the heat exchanger...

• Contamination: hydraulic system enemy no. 1
  ). This lets dissolved air escape from solution. Consider a system operating at 2,000 psi. An air bubble passing from the low pressure to the highpressure side of a pump compresses to about 1 135 its original size in less than 10 msec, producing considerable heat in the process. Typical diesel engines...
