CONTROL DEVICE FOR MOTOR-COMPRESSORS |
摘要 |
<p>A control device for motor-compressors in which the working medium is compressed in more than one stage and the power transmitted to the compressor is changed in dependence of the change of the pressure on the delivery side of the compressor above a certain value. The power adjusting mechanism for the motor is actuated in response to a pressure prevailing between two compressor stages to increase the power and in opposite direction for reducing the power by spring means and a control pressure bias on the adjusting mechanism responsive to a pressure change at the delivery side of the compressor so that an increased pressure change reduces the power supply.</p> |
