A method for promoting energy saving in fluid machinery reduces electric power consumption of fluid machinery by introducing an energy-saving device such as an inverter into existing fluid machinery such as a pump. The method comprises submitting data specifying characteristics of the fluid machinery of a user to a service provider, and estimating an energy-saving effect due to introduction of an energy-saving device into the fluid machinery based on the data specifying characteristics of the fluid machinery and an energy-saving ratio predetermined according to a purpose of fluid machinery. The method further comprises selecting an effective energy-saving device to be introduced, and surveying an operating state of the fluid machinery. The method further comprises calculating an energy-saving effect based on data obtained from the survey, and offering the estimated energy-saving effect, the calculated energy-saving effect, and the selected energy-saving device.

Method for promoting energy saving in fluid machinery

An apparatus for controlling performance of a fluid machinery by controlling rotational speed of the fluid machinery. A performance regulating device for the fluid machinery includes a frequency converter, a casing for housing the frequency converter so as to ensure being airtight against an atmosphere, an input, and an output connected to the casing so as to ensure being airtight against the atmosphere.

Performance regulating device for fluid machinery

The present invention relates to a pump for delivering under pressure various liquids including water. The temperature of the handled liquid in a pump casing ( ) is detected by a thermistor ( ). If an increase in the temperature per time of the handled liquid is greater than a predetermined value, then the pump is shut down, or the flow rate or pressure of the liquid is changed depending on the temperature of the handled liquid detected by the thermistor based on a predetermined control program.

Fluid machinery

A fluid machinery for generating a pressure by rotating an impeller with a motor has a frequency converter (F) for supplying electric power to the motor, a detector for detecting a frequency and a current value, and a program for specifying in advance the relationship between the frequency and the current value. A frequency and a current value in an actual operation are compared with the specified program, and the frequency generated by the frequency converter (F) is varied so that an operating point of the fluid machinery approaches the specified program.
