摘要:
A thermal control valve for use in a lubricant flooded compressor system including a controller that generates a control signal includes a valve body including a hot coolant inlet, a cooled coolant inlet, a mixed coolant outlet, an actuator space, and a cylinder bore. A sleeve is positioned within the cylinder bore and is movable between a first position, a second position, and a third position, and an electrical actuator is at least partially disposed within the actuator space and is operable in response to the control signal to move the sleeve between the first position, the second position, and the third position.

A portable electronic apparatus tests and diagnoses an electronic controller of a machine. The electronic apparatus includes an AC voltage detection means for sequentially detecting at least one high level AC voltage signal generated by at least one electronic controller output. A converter converts the at least one high level AC voltage signal to at least one low level DC voltage signal which simulates a low level contact closure input. A means is provided which sequentially inputs the at least one low level DC voltage signal to a low level DC voltage input of the electronic controller for detection by the electronic controller. A generator generates at least one analog voltage signal which simulates at least one known, fixed value operating parameter of the machine. A means is provided which inputs the at least one analog voltage signal to a predetermined electronic controller input for detection by the electronic controller. An indicator sequentially indicates the detection of the at least one high level AC voltage signal, the detection of the at least one low level DC voltage signal, and the detection of the at least one analog voltage signal.
摘要:
A fluid nozzle for the atomization of liquids and, more particularly, a three-fluid nozzle for effectuating a unique method of atomizing high viscosity liquids and difficult-to-spherize liquids which are to be spray-dried. Also disclosed is a novel method of atomizing high viscosity liquids and liquids which are difficult to spherize in an essentially two-step atomization sequence through the utilization of the inventive three-fluid atomizing nozzle.

A predictive vibration monitoring system for a machine includes a microcontroller and a machine to be monitored. The machine to be monitored includes at least one rotative element. At least one sensor is operatively connected to the machine. The at least one sensor is operable to convert mechanical motion generated by the at least one rotative element into a corresponding electrical signal. The at least one sensor inputs the corresponding electrical signal to the microcontroller. A communication means is disposed between the microcontroller and the monitored machine. The communication means enables the microcontroller to correlate a predetermined operational state of the monitored machine with a corresponding electrical signal generated by the at least one sensor. A memory means communicates with the microcontroller and stores a predetermined logic routine, at least one corresponding electrical signal and at least one predetermined key frequency of the at least one rotative element of the machine to be monitored. The microcontroller utilizes the predetermined logic routine to process the corresponding electrical signal into corresponding vibration data of the monitored machine. The microcontroller compares the corresponding vibration data with the at least one predetermined key frequency to predict the present and future condition of the at least one rotative element.
