摘要： The present invention aims to provide a motor-mounted internal gear pump that is small-sized, less expensive and has high reliability, while utilizing a function of an internal gear pump that is suitable for high head.
A motor-mounted internal gear pump has a pump section (81) for sucking and discharging a liquid and a motor section (82) for driving the same. The pump section (81) has an internal rotor (1) having teeth formed around its outer periphery, an external rotor (2) having teeth formed around its inner periphery and a pump casing that accommodates both rotors (1, 2) and has a suction port (8) for sucking a liquid and a discharge port (10) for discharging a liquid. The motor section (82) has a can (6) that composes a part of the pump casing and formed of a non-magnetic material into a thin plate, a rotator arranged at the inside of the can (6) for driving the external rotor or the internal rotor; and a stator (12) arranged at the outside of the can for rotating the rotator.

摘要： A vacuum pump system (10; 36; 46) for pumping gas from an enclosure (12) comprises: a vacuum pump unit (14) having a pump inlet (16) connectable with an outlet (18) of such an enclosure and a pump outlet (20) for exhausting gas; and a chamber (22; 50) selectively connectable with the pump inlet and the pump outlet, such that, in use, in a first state gas can be pumped from the chamber to the pump inlet by the vacuum pump unit and in a second state gas can be evacuated from the pump outlet to the chamber to reduce pressure at the pump outlet. A method of controlling the vacuum pump system (10; 36; 46) comprises a first step of pumping gas from the chamber to the pump inlet using the vacuum pump unit and a second step of allowing gas to be evacuated from the pump outlet to the chamber to reduce pressure at the pump outlet.

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： Die Offenbarung betrifft ein Verfahren zur Steuerung eines Schraubenverdichters mit mindestens einer ersten und einer zweiten Verdichterstufe, wobei beide Verdichterstufen getrennt voneinander und drehzahlregelbar angetrieben sind. Offenbarungsgemäß werden folgende Schritte ausgeführt: Erfassen eines am Ausgang der zweiten Verdichterstufe abgenommenen Volumenstroms; Anpassen der Drehzahl beider Verdichterstufen, wenn der abgenommene Volumenstrom in einem Bereich zwischen einem Maximalwert und einem Minimalwert schwankt; Öffnen eines Abblasventils, wenn der Volumenstrom den Minimalwert unterschreitet; Reduzieren der Drehzahl mindestens der ersten Verdichterstufe auf eine vorbestimmte Leerlaufdrehzahl (V1 L ), um den von der ersten an die zweite Verdichterstufe gelieferten Volumenstrom zu reduzieren.
Die Offenbarung betrifft auch einen Kompressor mit einem Schraubenverdichter, der mindestens eine erste und eine zweite Verdichterstufe umfasst, wobei beide Verdichterstufen getrennt voneinander und drehzahlregelbar angetrieben sind, und wobei eine Steuereinheit vorgesehen ist, welche zur Ausführung des vorgenannten Verfahrens konfiguriert ist.

摘要： System and method of remotely connecting and disconnecting an auxiliary power supply of the frequency inverter for variable capacity compressors employed in cooling systems. The inverter includes a circuit breaker that when it receives an external signal to activate the auxiliary power supply indicating that the auxiliary supply should be connected, the circuit breaker enables the auxiliary power supply, which activates the inverter. The inverter begins sending, continually, the internal maintenance signal to activate the auxiliary supply to the circuit breaker indicating that the auxiliary supply should be kept running, making the circuit breaker maintain the auxiliary power supply enabled. When the circuit breaker receives an external deactivation signal from the auxiliary supply indicating that the auxiliary supply should be disconnected, the inverter stops sending the signal to maintain the auxiliary supply activated to the circuit breaker, and the circuit breaker disables the auxiliary power supply, deactivating the inverter.
