A fan control unit measures the rotating speeds of the first and second fans to calculate the relative work intensities of the two fans. The control unit determines whether a difference between the first work intensity and the second work intensity is within a predetermined range. If the difference between the first work intensity and second work intensity is not in the predetermined range, the control unit adjusts a duty cycle of a pulse signal output to one of the first and second fans to change the rotating speed of one of the first and second fans to bring the difference between the first work intensity and the second work intensity within the predetermined range.

A multistage compressor installation in which compression stages utilizing centrifugal compressors are independently driven by drivers that can be electric motors configured to be controlled by a speed controller. Intercoolers are located between stages to remove the heat of compression and the stages are connected such that outlets are located opposite to inlets of the compressors and conduits connecting the intercoolers to the stages are in an in-line relationship to inhibit the formation of pressure drops between stages. The conduits connecting the stages incorporate tapered transition sections configured such that flow velocity gradually decreases towards the intercooler and gradually increases from the intercooler to the next succeeding compression stage to further inhibit pressure drops.

ANTI-SURGE SPEED CONTROL FOR TWO OR MORE COMPRESSORS

Принадлежит:

The present invention relates to a method and control system to control the speed of centrifugal compressors operating within a vacuum pressure swing adsorption process to avoid an operation at which surge can occur and directly driven by an electric motor that is in turn controlled by a variable frequency drive, while subsequently operating the vacuum pressure swing process between set limits of highest adsorption and lowest desorption pressure. In accordance with present invention an optimal speed for operation of the compressor is determined at which the compressor will operate along a peak efficiency operating line of a compressor map thereof. This speed is adjusted by a feed back speed multiplier when the flow or other parameter referable to flow through the compressor is below a minimum and a feed forward multiplier during evacuation and evacuation with purge steps that multiplies the feed back multiplier to increase speed of the compressor and thereby avoid surge. The speed is then adjusted by a global speed factor which serves to adjust the average speed of the motors over all steps of the repeating cycle such that the process operates within high and low pressure limits. 1.

A system for maintaining a high vacuum in a vacuum enclosure such as cryostat, for example, is described. The system includes a high-vacuum pump having an input that is connected to the cryostat and an output. A vacuum vessel is connected to the output of the high-vacuum pump. A second vacuum pump is connectable to the vacuum vessel. The system is operated such that the high-vacuum pump maintains the cryostat at a high vacuum and the second vacuum pump is periodically operated to maintain the pressure of the vacuum vessel below a threshold pressure. The second vacuum pump may be either permanently connected to, or removable from, the vacuum vessel. The vacuum vessel acts to maintain the output of the high-vacuum pump within a suitable pressure range. This removes the need for the output of the high-vacuum pump to be connected to a continuously operating, second-stage vacuum pump. Furthermore, the second vacuum pump is only required to be operated periodically in order to maintain the pressure in the vacuum vessel below the threshold pressure. 1.
