| 62 | Scroll type fluid machine | JP326982 | 1982-01-14 | JPS58122387A | 1983-07-21 | SUGIMOTO TAMIO |
| PURPOSE:To perform a performance control in spite of a simple structure by providing three or more crank shafts driven by motors respectively around the rotation center of a rotary scroll. CONSTITUTION:When a current is flowed through a motor stator 120, a crank shaft 70 is rotated through a motor rotor 13, and as the crank shaft 70 is rotated its rotation is transmitted to the shaft 502 of a rotary scroll 50, and three shafts 502 of the rotary scroll 50 are coupled with three eccentric holes 701, therefore the rotary scroll 50 is rotated without being revolved, then compressed gas is discharged through a discharge port 90. By using this device, a performance control can be performed and the power consumption at a light load can be reduced. | ||||||

| The invention relates to a method for controlling a rotary screw compressor, having at least a first and a second air-end, wherein both air-ends are driven separately from one another and speed controlled. According to the invention, the following steps are carried out: detection of a volume flow taken at the outlet of the second air-end; adjustment of the rotational speed of both air-ends, when the removed volume flow fluctuates in a range between a maximum value and a minimum value; opening of a pressure-relief valve, if the volume flow falls below the minimum value; and reduction of the rotational speed of at least the first air-end to a predetermined idling speed (V1L) to reduce the volumetric flow delivered by the first to the second air-end. | ||||||
