摘要： A pump has a housing that includes an inlet to receive a liquid to be pumped, an outlet to provide the liquid being pumped, a pumping chamber between the inlet/outlet; and a motor shaft to rotate in the pumping chamber. The impeller is arranged on the motor shaft, includes radially curved vanes to rotate inside the pumping chamber to pump the liquid from the pumping chamber to the outlet; and includes anti-airlock vanes formed as a set of axially curving vane extensions that extend along the axis of the shaft, rotate with one part inside the pumping chamber, protrude through the inlet and rotate with another part outside the inlet for submerging in liquid to be pumped underneath the pump, draw the liquid through the inlet into the pumping chamber, and provide the liquid to the radially curved vanes to generate pressure to force entrapped air from the pumping chamber.

摘要： A pump, having a pump housing with an impeller arranged therein, features an anti-airlock valve assembly configured with a valve housing having a passageway configured with a vent hole to allow air to bleed out of the pump housing into the atmosphere so liquid can fill the pump housing, rise and engage the impeller in order to get the pump running; and a valve ball arranged in the passageway, the valve ball configured to rest against one part of the passageway so air can pass out of the vent hole, and also configured to be light or buoyant enough to respond to the liquid filling the pump housing, float upwardly and rest against another part of the passageway so as not to allow water to escape readily from the vent hole after the liquid rises to a sufficient level and substantially engages the impeller.

摘要： Gas lock resolution during operation of an electric submersible pump is provided. An example method, module, or computing hardware with software product, detects a gas lock during current operation of an electric submersible pump (ESP) and intervenes to relieve the gas lock without stopping the ESP. After sensing a gas lock condition, an example module calculates a pump speed for attempting gas lock resolution. The example module may decrease the speed of the ESP to flush the gas lock, and then reaccelerate the ESP to check that the gas lock has been eliminated. The example module may apply one or more stored motor speed patterns that iteratively seek a pump speed that succeeds in clearing the gas lock, without stopping the ESP. The example module has built-in protections to protect the ESP from thermal overload and other damage.

摘要： On propose un organe servant à alimenter le moteur à combustion interne (18) d'un véhicule à moteur avec du carburant provenant d'un réservoir (10). L'organe d'alimentation (12) comprend une pompe d'alimentation disposée à l'intérieur du réservoir et se présentant sous la forme d'une pompe d'écoulement, dont la roue à ailettes (34) tournante, de forme essentiellement cylindrique circulaire, est disposée dans une chambre (36) correspondante, également cylindrique circulaire, et, dans une au moins des deux parois de la chambre, un canal d'alimentation (50) approximativement circulaire, de section en forme d'encoche, s'étend d'une ouverture d'aspiration (58) aboutissant à la chambre jusqu'à une ouverture sous pression (68) partant de celle-ci et cette paroi avant de la chambre est traversée, au niveau de l'ouverture sous pression, par un orifice (70) qui relie la chambre à une zone basse pression du circuit. On obtient, d'une manière simple, une extraction particulièrement fiable des bulles de gaz à l'extérieur de la pompe et donc de la section d'alimentation, par le fait que cet orifice est situé dans une surface étanche (64) qui délimite transversalement le canal d'alimentation relativement à l'axe de rotation de la roue à ailettes.

摘要： The invention relates to a delivery pump (2) for delivering fuel in a motor vehicle, comprising an impeller (7) with blade chambers (10, 10a, 11, 11a) which are delimited by guide blades (12, 13), and channels (14, 15) in the shape of incomplete circles. Said channels (14, 15) are located in housing parts (3, 4) adjacent to the impeller (7), in the area of the blade chambers (10, 10a, 11, 11a). The inventive pump also has a degasification channel (19), the start of said degasification channel being situated behind an inlet channel (8). Some of the blade chambers (10) are connected to the degasification channel (19) via pockets (20) incorporated in the impeller (7). This degasification channel (19) provides a reliable means of guiding the gas bubbles present in the fuel out of the delivery pump.
