摘要： 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.

摘要： Unique apparatuses, methods, and systems of opposing, limiting, and/or preventing undesired or un-commanded compressor rotation are disclosed. One exemplary embodiment is an HVACR system comprising a variable frequency drive configured to drive an electric motor to rotate a screw compressor or scroll compressor. A controller is configured to monitor various aspects of the system and to control the drive. When a condition indicative of potential undesired or un-commanded compressor rotation is identified, the controller commands the variable frequency drive to control the motor to limit and preferably prevent compressor rotation. One technique comprises shorting switches of the drive to a DC bus rail to allow back EMF induced current in the motor windings to be dissipated through winding resistance thus providing a damping force. Another technique comprises controlling the inverter to insert a DC current into the motor to cause the motor to align to and hold a particular position.

摘要： A system has a compressor and a consumer which are coupled to a drivetrain and extract energy through the drivetrain. The consumer is suitable for varying an absorption of power, which is made available to it by the drivetrain, as a function of a power which is required for compressor operation and which is supplied from the drivetrain to the compressor. A pump has at least one pump chamber which generates a pumping power during pumping operation. The pump additionally has at least one pump chamber which generates no pumping power or a reduced pumping power during pumping operation.

摘要： A compressor protection and control subsystem for a rotary compressor provides temperature pressure, mis-wiring and vibrational protection for the scroll machine. The vibrational protection comprises a vibration sensor which is integrated on the circuit board of the protection and control subsystem. The vibration sensor, in conjunction with at least one timer, monitors the vibrations of the scroll machine and will shut down the machine when excess vibrations are sensed over a prespecified period of time. The temperature system monitors operating temperature conditions the pressure system monitors operating pressures and the mis-wiring system monitors the power supplied to the compressor. Once an undesirable characteristic is identified, the operation of the scroll machine is stopped. These protection systems are integrated into a single subsystem which identifies the reason of shutting off the scroll machine in order to simplify repairs needed. The subsystem incorporates a gateway and/or a serial peripheral interface in order to communicate with a central operating and control system.

摘要： PROBLEM TO BE SOLVED: To reduce the required electric power of a vacuum pump apparatus by maintaining initial pressure to vacuum to reduce delivery pressure because the workload of the vacuum pump apparatus is proportional to pressure variation from the initial pressure to delivery pressure. SOLUTION: This vacuum pump system comprises the vacuum pump apparatus having an inlet connectable to an outlet of an enclosure, and an outlet for exhausting gas, and a chamber. The chamber is selectively connectable to an intake port and an exhaust port of a pump so that gas is pumped out to the intake port of the pump from the chamber by the vacuum pump apparatus in a first state during use and that gas can be exhausted to the chamber from the exhaust port to decompress the exhaust port of the pump in a second state. The method for controlling the system comprises a first step of pumping out gas to the intake port of the pump from the chamber using the vacuum pump apparatus, and a second step of allowing the gas to be exhausted to the chamber from the exhaust port to decompress the exhaust port of the pump.

摘要： Techniques are provided for tuning a twin screw positive displacement pump having a signal processor with a signal processor to receive signaling containing information about actual pump performance data for actual rated conditions captured during a tuning function related to the operation of a twin screw positive displacement pump; and determine corrected pump performance data to operate the rotary positive displacement pump by compensating pump performance data being used for operating the twin screw positive displacement pump based at least partly on the actual pump performance data for the actual rated conditions captured during the tuning function. The corrected pump performance data includes corrected published pump performance data having a corrected published rated power and slip factor, and the actual pump performance data contains information about actual power, specific gravity and viscosity related to the operation of the twin screw positive displacement pump and received from a pump controller or controlling device, including a variable frequency drive.
