    摘要： A liquid circulator is described that is configured to circulate liquids such as water, chemical mixtures, suspensions and the like. The liquid circulator includes an oscillation shaft, a circulation assembly mounted to the oscillation shaft, and a head unit located above the circulation assembly with a motor having an output shaft in driving engagement with the oscillation shaft. The liquid circulator may be devoid of a processor controlling operation of the liquid circulator. The circulator can also include a rotary to oscillation drive mechanism between the output shaft and the oscillation shaft that is configured to convert rotation of the output shaft into clockwise and counterclockwise oscillation of the oscillation shaft. In another example, an automatic clutch mechanism can be provided between the output shaft and the oscillation shaft.

    摘要： The present de-icing apparatus provides relatively small, portable, and adjustable devices for the specific purpose of de-icing a relatively small area of surface water for use by outdoor enthusiasts. The anchorable stand provides directional, surface height, and angular adjustment of the de-icing water flow to allow for establishing the preferred de-icing pattern at the water surface. De-icing means the reduction of freezing and the minimization of ice accumulation in a given surface area of the open body of water. The fixed-height vertical member of the anchorable stand provides a 360° adjustment range of output water flow. The adjustable-height vertical member of the anchorable stand provides surface height adjustment of the intake and output water flows. The vertical rotation point or points of the anchorable stand hold the water movement device and provide angular adjustment of the intake and output water flow.

    摘要： A propeller pump includes a pump housing and a pump core that is arranged in the pump housing and has a propeller, which together delimit a channel, and which are connected by a guide vane. The channel (27) haws a cross-sectional area (A2) at the rear edge (30) of the guide vane (13) that is greater than a cross-sectional area (A1) at the rear edge (29) of the blades (21) of the propeller. The specific rotational speed of the propeller pump is greater than 200 and less than 300.

    摘要： A fluid pump includes an inlet for introducing fluid into the fluid pump; an outlet for discharging the fluid from the fluid pump; a motor having an armature which rotates about an axis such that the armature is supported at one end by a first bearing and at second end by a second bearing, the motor also having a stator which circumferentially surrounds the armature such that a fluid passage is defined radially between the armature and stator through which the fluid flows from the inlet to the outlet; a pumping arrangement which is rotated by the armature and which pumps the fluid from the inlet to the outlet; a flow impedance member extending axially in the fluid passage which impedes circumferential flow of the fluid within the fluid passage, thereby generating a pressure gradient circumferentially within the fluid passage which applies a lateral force to the armature.

    摘要： The invention relates to a hydraulic pump (10) comprising a pump shaft (52) and a casing (46) delimiting a liquid circulation duct (44) in which the cross-section of the outlet orifice (12) is flattened and is oriented such that the liquid outlet direction (14) is inclined from a longitudinal axis (22) of the pump shaft passing through the casing, the casing comprising a first segment (100a) in which the inside surface (102a) has a circular cross-section centred on said longitudinal axis (22) and surrounding a pump impeller (60) supported on the pump shaft (52). According to the invention, the first segment (100a) has a downstream end starting from which the cross-section of the casing inside surface becomes flattened.
