摘要： Techniques are provided for tuning a twin screw positive displacement pump having a signal processor with a signal processor to receive signaling containing information about actual pump performance data for actual rated conditions captured during a tuning function related to the operation of a twin screw positive displacement pump; and determine corrected pump performance data to operate the rotary positive displacement pump by compensating pump performance data being used for operating the twin screw positive displacement pump based at least partly on the actual pump performance data for the actual rated conditions captured during the tuning function. The corrected pump performance data includes corrected published pump performance data having a corrected published rated power and slip factor, and the actual pump performance data contains information about actual power, specific gravity and viscosity related to the operation of the twin screw positive displacement pump and received from a pump controller or controlling device, including a variable frequency drive.

摘要： A gear pump includes a driven gear and an idler gear each mounted for rotation in a housing. The driven gear and the idler gear include respective gear teeth in a meshing relationship and forming an inlet space and an outlet space in the housing and adjacent to the meshing gear teeth. The inlet space is in fluid communication with the inlet port and the outlet space is in fluid communication with the outlet port. A flow indicating element is located in the housing and is mounted for rotation independent of the driven gear and the idler gear. The flow indicating element is configured to be rotated by the viscous fluid to indicate when the fluid is moving from the inlet port and inlet space to the outlet space and outlet port.

摘要： An oscillating variable displacement ring pump provides both positive and variable displacement. A housing circumscribes a pump chamber. The pump chamber encases an oscillating ring driven by a crank assembly. The ring encircles an end of the crank assembly. The crank assembly includes an annular spacer that rolls inside the ring. When the pump chamber is sealed, rotation of the crank assembly causes ring oscillation in the chamber. Ring oscillation creates vacuum pressure, which draws substances into pump chamber via an inlet port while pumping out substances of the pump chamber via an outlet port. A valve within the pump chamber contacts the ring and follows ring oscillation to help separate incoming substances from outgoing substances. The pump can include an adjustable internal by-pass means to control the volume and pressure of substances delivered by the pump.

摘要： A rotary fluid device includes a cylinder having an annular cylinder chamber and an annular piston, which is disposed in the cylinder chamber to be eccentric relative to the cylinder. The annular piston divides the cylinder chamber into an outer working chamber and an inner working chamber. A blade is disposed in the cylinder chamber to partition each of the working chambers into a high-pressure space and a low-pressure space. The cylinder and the piston relatively rotate. The outer working chamber constitutes a compression chamber which compresses and discharges a sucked fluid with the progress of the relative rotation of the cylinder and the piston. The inner working chamber constitutes an expansion chamber which expands and discharges a sucked fluid with the progress of the relative rotation of the cylinder and the piston.
