摘要： A system for noise and vibration management of a smoke evacuation system includes a pump that compresses air and produces a pressure differential within an airflow path. The pump may be a sealed, positive displacement pump. The system includes vibration absorption mechanisms disposed between inner and outer housings, as well as on the outside surface of the outer housing. Methods of controlling and regulating a motor of the system to preserve the lifespan of the motor and maintain consistent airflow rates throughout the smoke evacuation system include varying a supply of electrical current to the motor so that it can operate at variable performance levels. Orifices are opened and closed in order to relieve resistance pressures within the airflow path due to clogging and blockages.

The first scroll member includes a first end plate having a first spiral wrap extending therefrom. The second scroll member includes a second end plate having a second spiral wrap extending therefrom and an injection passage formed in the second end plate. The second spiral wrap is meshingly engaged with the first spiral wrap to form compression pockets. The injection passage is in fluid communication with the compression pockets. The fitting assembly is in fluid communication with the injection passage. The valve assembly coupled to one of the second scroll member and the fitting assembly and movable between a closed position in which fluid communication between the compression pockets and the suction chamber is prevented and an open position in which fluid communication between the compression pockets and the suction chamber is allowed.

摘要： Systems and methods for scroll unloading detection are provided and include a scroll compressor having a scroll compression mechanism. A controller determines a predicted discharge temperature of the scroll compressor, receives an actual discharge temperature of the scroll compressor, and compares the predicted discharge temperature with the actual discharge temperature. The controller also compares a speed of the scroll compressor with a speed threshold and detects unloading of the scroll compression mechanism based on the comparison of the predicted discharge temperature with the actual discharge temperature and based on the comparison of the speed of the scroll compressor with the speed threshold. The controller performs at least one of generating an alert and a remediating action in response to detecting the unloading of the scroll compression mechanism.

摘要： A motor-driven compressor includes an electric motor driven by a motor driver, which includes a switching element that converts DC voltage from a battery to AC voltage. A control unit controls the switching operation of the switching element. A temperature detector detects the temperature of the switching element. A voltage detector detects DC voltage applied to the switching element from the battery. The control unit suspends the switching operation of the switching element when the temperature detected by the temperature detector rises to a predetermined temperature threshold. The control unit also reduces counter electromotive force generated by the electric motor. The temperature threshold includes a first temperature threshold, corresponding to a withstand temperature of the switching element, and a second temperature threshold, which is higher than the first temperature threshold. The control unit switches the temperature threshold between the first and second temperature thresholds.

摘要： The invention enables quick evacuation of a chamber to a specified target degree of vacuum while increasing selectivity of evacuation conditions. A vacuum-processing device contains a chamber 40 that enables a workpiece to be soldered in a vacuum environment, an operating part 20 that sets a condition for evacuating the chamber 40, a pump 23 that evacuates the chamber 40, and a control portion 61 that calculates the amount of decrease in the degree of vacuum when evacuating the chamber 40 using a predetermined pump output, sets the calculated value as a reference value and switches an evacuation property from the evacuation property including a lower pump output to the evacuation property including a higher pump output when the calculated amount of decrease in degree of vacuum in real time has become smaller than the reference value.

摘要： A compressor provided with an oil stabilizing member capable of preventing oil stored in an oil storage space from being scattered is provided. A compressor may include a closed container provided with an inlet port and an outlet port, a compression unit configured to compress refrigerant introduced into an inside the closed container through the inlet port, a driving unit configured to provide a driving force to drive the compression unit, a rotating shaft configured to deliver the driving force to the compression unit, an oil storage space formed at a lower portion of an inside the closed container and configured to store a predetermined oil to come into contact with one end portion of the rotating shaft, and an oil stabilizing member installed so as to move along a surface of oil formed at the oil storage space, thereby preventing the oil from being scattered and thus released through the outlet port, wherein the oil stabilizing member floating on the surface of the oil prevents oil from being scattered upward according to operation of the compressor.

摘要： A method includes determining a pressure difference across a scroll compressor of a cooling system. The pressure difference is compared to a minimum differential pressure value. Pressure differences across the scroll compressor that are less than the minimum differential pressure value are associated with unloading the scroll compressor. Parameters including a pressure set point value and an absolute minimum pressure value are increased when the pressure difference is less than the minimum differential pressure value. Subsequent to the increasing of the parameters, the parameters are decreased when the pressure difference is greater than a sum of the minimum differential pressure value and a hysteresis value.
