Abstract: In a method for controlling a compressor (2) in a closed level adjustment system, the actual compressor temperature is continuously determined, at least during operation of the compressor, and the compressor (2) is disconnected when it reaches a threshold temperature. Admission pressure and counter-pressure of the compressor are taken into account in order to determine the actual compressor temperature. Preferably, the actual compressor temperature t is adapted by a value dT after each unit of time has elapsed while the compressor is operating, said value depending upon the difference between counter pressure and admission pressure (pcounter−padmission).

Abstract: A pressure sensor subsystem measures the pressure within a fuel pump and outputs an under-pressure signal when the measured pressure is below a predetermined threshold pressure value. A temperature sensor subsystem measures the temperature within the fuel pump and outputs an over-temperature signal when the measured temperature is above a predetermined threshold temperature value. A timing circuit monitors the pressure sensor subsystem and the temperature sensor subsystem for output of the under-pressure and over-temperature signals and outputs a pump disconnect signal when at least one of the signals is output for a prescribed time duration. A power controller disengages power from the pump upon output of a pump disconnect signal by the timing circuit.

Abstract: An apparatus for protecting a fluid pump motor includes an electric motor for driving a pump head to pressurize a fluid. A liner is positioned in the motor air gap to prevent pressurized fluid from contacting one or more magnetic field producing elements of the stator. The liner includes a thin wall to minimize the air gap distance. The liner wall is made thin enough that, under loading of the pressurized fluid, the liner wall deforms and bears against one or more of the field producing elements of the stator for structural support. The liner is preferably fabricated as a single metal part using a deep drawing process that results in a can having opposed open and closed ends with a substantially uniform cross-section between the open and closed ends of the can.

Abstract: A fluid impermeable barrier is provided to protect the rotor of an electric motor. The barrier includes a body portion with a relatively large opening at one end to receive the rotor laminations and a smaller opening at the other end to receive one end of the rotor shaft. With the body portion positioned about the laminations, a cap with an outer perimeter and central opening is slid down the other end of the rotor shaft to close the large opening in the body portion. The assembly is completed by sealingly attaching the outer perimeter of the cap to the large opening in the body portion and sealingly attaching the smaller openings in the cap and body portion to respective portions of the rotor shaft. Thus, the fluid impermeable rotor barrier includes no more than two parts that are assembled onto the rotor using no more than three areas of attachment.

Abstract: A reciprocating piston type compressor for compressing refrigerant gas for an automobile air conditioning system is improved to protect itself without protective control by a computer. The compressor detects the temperature of a part of the compressor in which the temperature increases to higher than a predetermined critical temperature when the compressor malfunctions, and changes a displacement control valve to reduce the displacement of the compressor when the detected temperature is higher than the predetermined critical temperature.

Abstract: A rod-pump control device is disclosed. The claimed rod-pump control device uses fuel or air usage for gas units, and can use pressure. The sensors work as the primary trigger to indicate a pump-off condition on an oil and gas well. These sensors can be used as stand-alone triggers or in conjunction with other sensors to more accurately monitor pump efficiency. When the pump-controller starts to indicate an inefficient pump condition, it will remove power to disengage an electric clutch or send a signal to an engine controller to stop. An adjustable algorithm will use percentage change of off time, dependent on actual run time compared to a user definable target time to keep the pump operating at peak efficiency.

Abstract: A cryopump includes an accommodation space for a condensed layer of gas, a first-stage cryopanel having an inner surface of the first-stage cryopanel disposed so as to surround the accommodation space, and a second-stage cryopanel disposed so as to be surrounded by the inner surface of the first-stage cryopanel together with the accommodation space. A first-stage heat load is incident on the inner surface of the first-stage cryopanel from outside the cryopump through an intake port, and the gas enters the accommodation space from outside the cryopump. The first-stage cryopanel is cooled to a temperature higher than a condensation temperature of the gas, the second-stage cryopanel is cooled to a temperature of the condensation temperature or less, and the condensed layer is deposited. The cryopump monitors the amount of condensed gas in the accommodation space based on a change in the first-stage heat load.

Abstract: Provided is a configuration which prevents an engine from being unable to start in the state in which dew condensation occurred in a fuel injection pump and froze. The present invention relates to a fuel injection pump which is provided with a pump body and a hydraulic head and driven by an engine, and is characterized in that while the engine is in operation, the temperature of the hydraulic head is increased to a dew-point temperature or higher. Consequently, it is possible to increase the temperature of the hydraulic head and remove water in the fuel injection pump while the engine is in operation. Accordingly, the engine can be prevented from being unable to start in the state that dew condensation occurred in the fuel injection pump and froze.
