Embodiment Construction

[0010] Such as figure 1 As shown, the water guiding mechanism for a vertical water pump of the present invention includes a plurality of water pump units 1, and each water pump unit 1 is connected together in a stacked manner by means of a pump shaft 2 and a locking mechanism. The lower end of the pump shaft 2 protrudes under the lowermost water pump unit 1 , and the lower end is covered with a sleeve 3 , and the sleeve 3 is sleeved on the pump shaft 2 in an axially fixed manner by means of screws. A helical guide vane 4 is processed on the outer circle of the casing 3 . The vertical projection diameter of the spiral guide vane 4 is smaller than the vertical projection diameter of the impeller in the water pump unit 1 . When working, the casing 3 and the spiral guide vane 4 on the outer circle of the casing 3 rotate together with the pump shaft 2, and the water is first introduced into the water pump and then into the impeller of the water pump, thereby reducing the water abs...

Abstract

The invention discloses a water guiding mechanism for a vertical water pump, in particular a water guiding mechanism for a vertical water pump, which is used for reducing water absorption resistance and improving water absorbing capacity. The water guiding mechanism comprises at least two water pump units; the water pump units are connected together in an overlapped manner by means of a pump shaft and a locking mechanism. The water guiding mechanism is characterized in that the lower end of the pump shaft extends out to reach below the lowermost water pump unit; a sleeve sleeves the downwards extending end of the pump shaft; the sleeve axially fixedly sleeves the pump shaft; the outer circle of the sleeve is provided with a spiral guide vane; the diameter of the vertical projection of the spiral guide vane is smaller than the diameter of the projection of an impeller in each water pump unit. By adopting the water guiding mechanism, the water absorption resistance of the vertical water pump can be reduced, the water amount entering the water pump is increased, and the work efficiency of the water pump is improved.

Description

technical field [0001] The invention relates to a water pump. Specifically, it is a water guide mechanism for vertical water pumps used to reduce water absorption resistance and increase water absorption. Background technique [0002] It is known in the field of vertical water pump production that the lower end of the current vertical water pump, that is, the pump shaft end of the water inlet, has no water guide mechanism, and the impeller of the bottommost water pump directly sucks water into the water pump. Because there is no water guiding mechanism, the impeller of the water pump on the lowest floor directly sucks water into the water pump, so that the water absorption resistance of the water pump is relatively large, and the amount of water entering the water pump is less. Therefore, the working efficiency of this water pump is not high. Contents of the invention [0003] The problem to be solved by the present invention is to provide a water guiding mechanism for a...
