“…[18][19][20][21][22] (e) Processing and manufacturing is made difficult by miniaturization of the pump. 3,23,24 The main purpose of this study is to provide a base model of high-pressure and high speed gear pump for addressing the above problems. A circular-arc tooth profile is introduced and the flow rate, radial force, axial force, and torque are studied.…”

This paper presents a high-pressure and high-speed gear pump for aerospace application and introduces a circular-arc tooth profile that has no trapping feature and whose gears are in continuous one-point contact in the plane of rotation. Basic dimensions are determined and performance parameters of the gear pump are obtained by structural design of the gear pump. The performance parameters are discussed for different tooth profiles. A disc tool and hob are designed to generate the circular-arc tooth profile. A computer-aided design (CAD) system for the design of the circular-arc gear pump is developed with features of tooth profile design, tool design, and numerical control. The test gears were processed to verify the correctness of CAD system. A study of the outlet pressure of the circular-arc gear pump reveals that the developed high-pressure and high-speed gear pump has low outlet pressure fluctuations.

This paper presents the way of identifying the influence of the tolerance of model pumps (TYPE 3PWR-SE) construction on the total efficiency. The identification of sensitive control dimensions (Value / Tolerance) of examined pumps has been made by means of the multi-valued logic and inductive decision trees. In order to confirm the obtained results, multiple-valued logic trees have been used in the paper according to algorithms for the minimization of individual logic functions.What is more, a specific monotonicity of values of the most key parameters has been determined for the investigated set of pumps having individual specification numbers.

“…Johannes Kepler created the first gear unit in 1604. The primary application of the patented solution at that time was to pump water in dehydrated mines [1,[2][3][4][5][6][7][8][9]. The valveless and self-priming gear construction resistant to numerous contaminations present in the water removed from shaft wells very quickly replaced hard to use piston pumps used at that time.…”
