    Abstract: A low profile positive displacement pump system is disclosed. The pump system includes a gasoline powered engine with a vertically disposed crank shaft. The system also includes a piston pump with at least one horizontally disposed piston, and a pump shaft assembly which mounts onto the crank shaft. A base includes a cavity configured for retaining the pump. The engine mounts directly onto the base, and fixes the orientation of the pump shaft assembly with respect to a driven end of each piston. The pump shaft assembly includes at least one eccentric camming surface for contacting a driven end of the piston and for causing each piston to complete one stroke per revolution of shaft rotation. The base comprises a main body including an upper surface, wherein the upper surface is suitable for mounting directly to a mounting flange of the gasoline powered engine.

    Abstract: PROBLEM TO BE SOLVED: To improve the radiation of the resin air tank of an air pump, and easily and certainly attach the air tank. SOLUTION: The air tank (20) temporarily stores air from a pump body (12) and discharges it. The air tank includes: a tank body provided with a top wall (40) placing the pump body and a peripheral wall (42) extending downward from the top wall, and formed with a downward opening; and a metallic bottom wall member (46) attached in a manner that it abuts on the bottom surface of the peripheral wall to tightly close the opening of the tank body. Bolts are fastened after being passed through the metallic bottom wall member and the metallic portion of the pump body, thereby connecting and fixing the pump body and air tank.

    Abstract: A rod-pump control device is disclosed. The rod-pump control device uses AMP (current) measurements for electric units, fuel or air usage for gas units, and can use pressure for either unit. The AMP/fuel/air 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 turn the pump off by removing power from the electric motor. For gas powered units, the controller 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 pumps gas from a vacuum chamber in a vacuum apparatus performing vacuum processing. The cryopump comprises: a refrigerator; a cryopanel cooled by the refrigerator; and a controller configured to control an operating cycle of the refrigerator such that the cryopanel is controlled so as to have a target temperature. When an operating cycle of the refrigerator has reached a first determination reference, the controller monitors the operating cycle for a first determination period of time, and when the operating cycle has reached a second determination reference, which corresponds to a higher load than the first determination reference, the controller monitors a temperature of the cryopanel for a second determination period of time, which is shorter the first determination period of time.

    Abstract: In a method for controlling the operation of a compressor, the compressor is switched off by a controller in order to prevent thermal damage if an estimated temperature value calculated by the controller exceeds an upper threshold value. The controller calculates a cooling function as a state variable utilizing the estimated temperature value, the cooling function representing the chronological course of the cooling of the compressor. The controller determines the cooling function based on at least one first and one second estimated temperature value which are associated with points of the compressor that are at spatial distances to each other. The calculation of the cooling function is based on a temperature difference between the first and second estimated temperature values.
