摘要： An apparatus for electronically controlling the flow of low pressure gas to a compressor and preventing backflow from the compressor, the apparatus including a housing in fluid communication with the compressor, where the housing has a chamber, a housing inlet for receiving a low pressure gas, and a housing discharge port for flowing the low pressure gas to the compressor and through which backflow gas flows from the compressor. A valve member having a contact end is movable within the chamber along a predetermined path. The apparatus also includes a drive for moving an actuator along an axis. The actuator has an extension with an end adapted to abut the contact end of the valve member to thereby move the valve member along the path toward the housing inlet. The valve member is movable along the path and away from the inlet, when the actuator is retracted, by the flow of low pressure gas through the inlet. Upon compressor shutdown, the back pressure moves the valve member to a substantially occluding position relative to the inlet position to prevent backflow from flowing outward from the compressor.

摘要： A compressor, used for compressing a working fluid to be discharged into a reservoir, includes at least one compressor element. A prime driver, capable of operating at varying angular velocities, applies motive force to the compressor. A ratio maintaining device, disposed between each compressor element and the prime driver, ensures that a ratio defined as an angular velocity of the compressor element divided by the angular velocity of the prime driver remains constant. The prime driver is typically internal combustion engine powered. A controllable fuel valve is in communication with the prime driver and is positionable for controlling a fuel flow to the prime driver. A controller positions the fuel valve based upon a combination of parameters including a variable setpoint reservoir pressure, ambient pressure and ambient temperature, wherein the prime driver is operated at an angular velocity at which the actual pressure at the reservoir can be maintained at the setpoint reservoir pressure. The controller is microprocessor or microcomputer based.

摘要： A system and method for controlling the temperature of the compressed fluid flowing through a compressor aftercooler. The system includes a compression module flow connected to an aftercooler and at least one repositionable fluid flow regulating member upstream from the aftercooler for modifying the volume of ambient fluid supplied across the aftercooler. The system further includes a temperature sensor for sensing the ambient temperature, and an actuator connected to the at least one fluid flow regulating member. A controller is in signal receiving relation with the temperature sensor and is in signal transmitting relation with the actuator. If the sensed ambient temperature is outside a predetermined range, a repositioning signal is sent by the controller to the actuator, extending or retracting the actuator the amount required to achieve the required fluid flow rate across the aftercooler and thereby maintain the desired aftercooler fluid discharge temperature for the ambient operating temperatures.

摘要： A method for optimizing the operating efficiency of a compressor having a compression module for compressing a fluid, the compression module including an inlet for receiving the fluid and an outlet for discharging compressed fluid, the compressor including a prime mover for driving the compression module and a rotatable fan for drawing ambient air into the compressor. The compressor includes a first temperature sensor for sensing the temperature of compressed fluid discharged from the compression module, a second temperature sensor for sensing the temperature of a coolant circulating through the prime mover, a third temperature sensor for sensing the temperature of the fluid entering the compression module, and a fourth temperature sensor for sensing the temperature of a lubricant mixed with the fluid as the fluid is compressed in the compression module. The compressor includes an electronic control module (ECM) electrically connected to the four temperature sensors for receiving signals therefrom. The ECM includes a non-volatile memory containing empirical data relating to optimal operating set points of the compressor and a logic routine for controlling the rotational speed of the fan and the volume of the lubricant mixed with the fluid so as to optimize the efficiency of the compressor. The method includes the steps of executing a temperature sensing subroutine whereby the first, second, third and fourth temperature sensors collect temperature data and relay the temperature data to the ECM, executing a fan speed subroutine whereby the ECM generates signals in response to the temperature data received by the ECM for controlling the rotational speed of the fan, and executing a lubricant volume control subroutine whereby the ECM generates signals in response to the temperature data received by the ECM for controlling the volume of the lubricant mixed with the fluid in the compression module.

摘要： A gas compressor includes a compression module, an adjustable inlet valve for precisely controlling the supply of a compressible gas to the compression module, and a pressure sensor for sensing a pressure of the gas discharged from the compression module. The gas compressor also includes an internal combustion engine for driving the compression module, the internal combustion engine having a cooling system including an engine coolant, a coolant sensor for sensing a temperature of the engine coolant, the coolant sensor being in signal sending relation with the electronic control module, a fuel control device for controlling the amount of fuel supplied to the internal combustion engine and an electronic control module (ECM) having a memory and a logic routine for controlling operation of the compressor. The ECM has a set point speed for the engine and a set point minimum coolant temperature for the engine stored in the memory. The ECM is in communication with the coolant sensor for receiving the sensed temperature of the engine coolant. The ECM is also in communication with the pressure sensor for receiving the sensed discharge pressure and comparing the discharge pressure to a set point discharge pressure range stored in the memory. The ECM generates a signal for positioning the adjustable inlet valve so that the discharge pressure remains within the set point pressure range. A method for controlling the gas compressor includes executing a compressor start routine including the steps of opening the fuel control device for supplying fuel to the engine, and accelerating the engine to the set point speed stored in the memory of the electronic control module. After the internal combustion engine reaches the set point speed, the ECM executes the compressor load routine including sensing an actual temperature of the engine coolant and comparing the actual temperature of the engine coolant to the set point minimum coolant temperature; and opening the adjustable inlet valve after the actual engine coolant temperature is at least equal to the set point minimum coolant temperature, wherein the position of the adjustable inlet valve is controlled by the ECM.

摘要： A method and apparatus for controlling working fluid surge in a centrifugal compressor include preventing surge by using a variable-speed prime-mover to achieve a minimum desired surge margin. Surge prevention is also accomplished by continuously modulating a blowoff valve to maintain an actual compressor pressure ratio at a predetermined target maximum value. Surge detection is accomplished by monitoring the time rate of change of the final stage discharge pressure.
