    摘要: Embodiments of the systems and methods disclosed herein utilize a brushless DC motor (BLDCM) to drive a single-stage or a multi-stage pump in a pumping system for real time, smooth motion, and extremely precise and repeatable position control over fluid movements and dispense amounts, useful in semiconductor manufacturing. The BLDCM may employ a position sensor for real time position feedback to a processor executing a custom field-oriented control scheme. Embodiments of the invention can reduce heat generation without undesirably compromising the precise position control of the dispense pump by increasing and decreasing, via a custom control scheme, the operating frequency of the BLDCM according to the criticality of the underlying function(s). The control scheme can run the BLDCM at very low speeds while maintaining a constant velocity, which enables the pumping system to operate in a wide range of speeds with minimal variation, substantially increasing dispense performance and operation capabilities.

    摘要: An apparatus for mixing and pumping manure slurry from a manure pit comprises a pump unit having first and second mixing rotors and a pumping rotor. In operation, the first mixing rotor draws solids downwardly towards the pump unit while the second mixing rotor redirect a portion of the solids drawn by the first mixing rotor away from the pump unit, thereby allowing to control the ration of solid contents in the slurry pumped by the pumping rotor. A non-diverted flow distribution arrangement is also provided for selectively connecting the pump outlet in straight-through flow connection with either a drainage pipe or a re-circulation pipe.

    摘要: Provided is a system for transporting an oil sand slurry, comprising a pump, upstream and downstream lines, a shaft connectable to the pump, a driving mechanism driving the pump and a regulator for regulating the torque applied to the shaft between positive and negative torque modes, to pump the slurry at higher or lower flow rates. Also provided is a method comprising pumping the slurry through a pipeline using a pump driven by a motorised shaft and adjusting the flow rate of the slurry by varying the torque applied to the motorised shaft between positive and negative torque modes. The oil sand slurry transportation system and method enable positive head (regular pump action) for normal and high flow rates and negative head (pump brake action) for low flow rates, which reduces system energy loss, pipeline wear, vapour breakout and sanding off.

    摘要: A device and a method for controlling a two-cylinder thick matter pump comprising pistons that are actuated in a push-pull manner by means of a hydraulic reversible pump (6) and hydraulic drive cylinders controlled by said pump. To ensure a reliable operation of the pump the expected length of the stroke of the pistons (8, 8′) in the drive cylinders (5, 5′) is measured and recorded, the stroke time of each conveyance stroke is monitored and compared with the expected stroke duration, and the reversible pump (6) is respectively pivoted, reversing the flow, and/or the pipe switch (56) is reversed when the stroke time exceeds the expected stroke duration by a pre-determined value.

    摘要: There are a number of applications today where the pumping of abrasive slurries is necessary. The pumping mechanisms, though, can be complex, employing multiple transfer cylinders and movable pipes. These designs have their problems, specifically wear between poorly sealing surfaces. To reduce this problem, seals are provided that have multiple wear surfaces which include harder tiles secured over a softer core to benefit from the relative hardness or flexibility of each of the respective materials.
