摘要： Provided is a compressor capable of calculating the correct time remaining before maintenance. The compressor is provided with: a compressor body that compresses fluid; a motor that drives the compressor body; a temperature sensor that detects the temperature of the compressor; a pressure sensor that detects the pressure of the compressed fluid outputted from the compressor body; and a calculation unit that calculates the time remaining before maintenance for the compressor body, using the temperature of the compressor and the pressure of the compressed fluid assigned with respective predetermined weights. The calculation unit changes the weighting of the temperature according to the pressure of the compressed fluid or the operation rate of the compressor body.

摘要： A fluid pumping system includes a fluid pump, an actuator coupled to the fluid pump, and a controller operatively coupled to the actuator. The controller is configured to detect an irregular condition of at least one of the fluid pump, the actuator or the controller, and upon detecting the irregular condition, to modify at least one operating parameter of the actuator to prevent the irregular condition from transitioning to a fault condition.

摘要： A compressor assembly (10) configured to increase pressure of a fluid. The compressor assembly includes a cylinder (12a, 12b) forming a space for compressing the fluid and a piston (14a, 14b) configured to reciprocate in the cylinder to compress the fluid. The compressor assembly includes a crank shaft (72) configured to drive the piston and a crank shaft housing (18a, 18b) operatively connected to the cylinder and configured to house the crank shaft. A motor (20) is connected to the crank shaft and drives the crank shaft. The compressor assembly further includes a motor housing (22) connected to the crank shaft housing and configured to house the motor. A thermal insulator (24a, 24b) is disposed between the motor housing and the crank shaft housing to enhance thermal insulation between the motor housing and the crank shaft housing.

摘要： Disclosed is a method for controlling operation of a compressor, according to which the compressor is shut off by a control device in order to prevent thermal damages when an estimated temperature value Ts calculated by said control device exceeds an upper threshold value Tmax while the compressor remains on or is allowed to be turned on when there is a need for compression and a lower threshold value Tmin is not reached. In order to be able to more accurately estimate the estimated temperature and increase the thermal availability of the compressor, the estimated temperature value Ts is indirectly and cyclically determined by means of a mathematical-physical model that characterizes the cooling and heating properties of the compressor.

摘要： Bei einer insbesondere für einen Kühlmittelkreislauf eines Verbrennungsmotors eines Kraftfahrzeugs bestimmten Pumpe (1) ist ein in die Pumpe integrierter Temperatursensor (3) zur Erfassung der Temperatur der in eine Pumpenkammer (4) einströmenden Flüssigkeit vorgesehen. Der Temperatursensor (3) ist hierzu in eine Ausnehmung (10) eines Pumpengehäuses (9) der Pumpe (1) eingesetzt, welche im Bereich (11) des Temperatursensors (3) zu einer reduzierten Wandstärke (d) führt. Hierdurch kann der Wärmedurchgang durch das Pumpengehäuse (9) von der Flüssigkeit auf den Temperatursensor (3) verbessert und der Herstellungsaufwand reduziert werden. Weiterhin kann der Temperatursensor (3) hierbei auf einem mit einer Steuerung (15) der Pumpe (16) gemeinsamen Trägermaterial (14) angeordnet werden, wodurch die Störanfälligkeit der Kontaktierung des Temperatursensors (3) reduziert wird.

摘要： The invention relates to a pneumatic suspension system, especially for motor vehicles, with a compressor which can be switched on and off as necessary depending on parameters by an automatic computer-supported control system. The computer of the control system provides an estimate of the operating temperature of the compressor on the basis of experimental values so that said compressor can be switched off when a predetermined threshold is exceeded.

摘要： A method for calculating the probability of moisture build-up in a compressor includes the steps of sensing a temperature of the ambient air, sensing a discharge pressure of the compressor, sensing a temperature of the compressor, processing the ambient air temperature and operating pressure sensed to obtain a required temperature at which condensation will form, and comparing the temperature of the compressor to the required temperature.
