摘要： A sampling pump is disclosed for pumping liquids collecting in a wellbore. The sampling pump has a pump component having an inlet and an outlet, a pump element and DC motor for driving the pump element. A reel assembly having a reel and a frame supports a cable assembly wound on the reel. The cable assembly supplies power to the DC motor. A DC connector supported on the frame enables an external DC power source to power the DC motor. A fluid level sensor on the housing detects when the outer housing is positioned in fluid. A control panel on the frame is in electrical communication with the fluid sensor and configured to enable a user to control on and off operation of the DC motor.

摘要： A fine control gas valve includes a tee having opposed first and second tee runs co-axially aligned on a longitudinal axis, and a tee branch. A valve assembly is partially received in and connected to the first tee run having a valve disc connected to a drive screw longitudinally moved by drive screw axial rotation. The valve disc includes a first slot on the valve disc having a first end and a wider second end, and a second disc slot as a mirror image of the first disc slot oppositely positioned about the valve disc. A pipe in the second tee run has a first portion of a pipe end face/seat surface in direct contact with a second tee run shoulder. The valve disc when contacting a second portion of the pipe end face/seat surface defines a valve closed condition. The first and second portions are co-planar to each other.

摘要： A pump apparatus for pumping undergound fluids from a well. The pump includes inner and outer chambers, and a float slidable within the outer chamber. A source of compressed air is directed to a valve on the pump. The valve controls the flow of the compressed air into the outer chamber during the pumping cycle, and also controls the opening of a vent during the intake cycle. The float, while sliding up and down within the outer chamber in response to the fluid level within the chamber, activates the valve to begin the pumping of fluid when the chamber is full. When the chamber is empty, the float activates the valve is turn off the compressed air.
摘要翻译：用于从井中泵送流体的泵装置。泵包括内室和外室，以及可在外室内滑动的浮子。压缩空气源被引导到泵上的阀。阀门在泵送循环期间控制压缩空气进入外室的流量，并且还可以在进气循环期间控制排气口的打开。浮子同时在外室内上下滑动以响应腔室内的液位而启动阀门，以在腔室充满时开始泵送流体。当室内空时，浮子启动阀门关闭压缩空气。
