摘要： The invention relates to an impeller (1), in particular for a side channel machine, having blades (5) which are arranged distributed in the circumferential direction, are formed in each case by a blade wall (6) and form open blade chambers (4) in a plan view of the impeller (1), wherein a blade wall (6) begins, in plan view, at a first radius dimension (r
1 ) in relation to the geometric impeller rotational axis (x), which radius dimension (r
2 ) corresponds to half or more of a second radius dimension (r
2 ), which radius dimension (r
2 ) defines a circumferential edge (9) of the impeller (1), and wherein the radius dimension (r
2 ) defines a radially inner boundary wall (7) of the blade chamber (4), wherein, furthermore, a blade wall (6) has an exposed upper termination edge which correspondingly runs radially on the inside into the inner boundary wall (7) and ends radially on the outside in plan view, wherein an imaginary connecting line (V) can be drawn between a run-in point of the termination edge into the inner boundary wall (7) and a radially outer end of the termination edge (12), and the termination edge runs perpendicularly with respect to the connecting line (V) with a different offset dimension, wherein a greatest offset dimension is given. For advantageous development, in particular with regard to an improved degree of efficiency, it is proposed that the greatest offset dimension corresponds to 0.1 times or more the difference of the second (r
2 ) and the first radius dimension (r
1 ).

摘要： A random pitch impeller for a fuel pump has number of blades. An incremental angle of the blades is set by the expression: Δ ⁢ θi = 360 N + - 1 i × Am × sin p 1 × 360 N × i × cos P 2 × 360 N × i ,
where ΔθI is the incremental angle between the blades, N is the total number of blades (N=2, 3, 5, 7, 11, 13, 17,...), Am is the distribution magnitude of the inter-blade interval (equally divided angle) (0 1 and P 2 are the factors exerting an influence on the cycle (0 1 2 ≤ N). The incremental angle has maximum and minimum values a difference of which satisfies the expression: 2° ≤ MAX - MIN ≤ 6°, where MAX is the maximum value, and MIN is the minimum value of the incremental angle.

摘要： A fluid pump may include an electric motor having an output shaft driven for rotation about an axis and a pump assembly coupled to the output shaft of the motor. The pump assembly has a first cap and a second cap with at least one pumping channel defined between the first cap and the second cap, and an impeller received between the first cap and the second cap. The impeller is driven for rotation by the output shaft of the motor and includes a plurality of vanes in communication with the at least one pumping channel. Each vane has a root segment and a tip segment and a line from a base of the root segment to an outer edge of the tip segment trails a line extending from the axis of rotation to the base of the root segment by an angle of between 0° and 30° relative to the direction of rotation of the impeller.

摘要： In prior art, delivery units comprise a running wheel which is arranged in a pump chamber and which can be driven in a rotated manner by means of an actuator and comprise two front sides whereby a front wall of the pump chamber is arranged opposite thereto, and also comprises several recesses for storing, in a hydrodynamic manner, in both front sides of the running wheel. One disadvantage of the delivery unit is that dirt particles can collect in the recesses. When the dirt particles are flushed out from the recesses, they produce, in the region between the recesses which are arranged in a circular manner, increased friction and also stress marks and the axial gap between the running wheel and the pump chamber is smaller than in the region of the recesses. The inventive delivery unit reduces the friction acting upon the running wheel and increases efficiency. According to the invention, at least two adjacent recesses (38) of the at least one front side (28,29) and/or the at least one front wall (15,16) are connected together by, respectively at least one groove (42).
摘要翻译：在现有技术中，输送单元包括布置在泵室中并且可以借助于致动器以旋转方式驱动的运行轮并且包括两个前侧，由此泵室的前壁与其相对布置，并且还包括多个凹槽，用于以流体动力的方式在转轮的两个前侧存储。输送单元的一个缺点是污物颗粒会聚集在凹槽中。当污物颗粒从凹槽中冲出时，它们在以圆形方式布置的凹槽之间的区域中产生增加的摩擦并且还产生应力痕迹，并且在运行轮和泵室之间的轴向间隙小于凹陷的区域。本发明的输送单元减少了作用在行走轮上的摩擦并提高了效率。根据本发明，至少一个前侧（28,29）和/或至少一个前壁（15,16）的至少两个相邻凹槽（38）分别通过至少一个槽（ 42）。

摘要： An impeller for a circumferential current pump is injection molded and can be used as it is without being polished. The impeller (7) is provided with a plurality of vane grooves (12) on an outer periphery of a synthetic resin disc-like member (8) rotated by a motor, and is rotatably received with a substantially disc-like space (6) formed between a pump casing (4) and a pump cover (5). A disc-like recess portion (14) is formed in both side surfaces (10,11) of the disc-like member (8).
A plurality of grooves extending in a radial direction are formed in a recess portion (14) of the impeller.
