Description

一种可调节底座的水泵Water pump with adjustable base 技术领域Technical field
本发明涉及潜水泵，具体说是一种可调节底座的水泵。  The invention relates to a submersible pump, in particular to a water pump with an adjustable base.
背景技术Background technique
潜水泵是利用叶轮高速旋转，其中吸入腔体里的液体随着叶轮叶片一起旋转，在离心力的作用下，飞离叶轮向外射出，射出的液体在泵壳内速度逐渐变慢，压力逐渐增加，然后从泵的出水口流出。此时，在叶轮叶片中心处，由于液体被甩向周围而形成既没有空气又没有液体的真空低压区，液池中的液体在池面大气压的作用下，经吸入口流入泵体内，液体就是这样连续不断地从液池中被吸入泵的腔体内，又被从泵的出水口甩出来，连续不断地从排水管流出。The submersible pump uses the impeller to rotate at a high speed. The liquid in the suction chamber rotates with the impeller blades. Under the action of the centrifugal force, the liquid is emitted from the impeller, and the velocity of the liquid in the pump casing is gradually slowed down and the pressure is gradually increased. And then flow out of the pump's water outlet. At this time, at the center of the impeller blade, since the liquid is smashed to the periphery to form a vacuum low-pressure zone having neither air nor liquid, the liquid in the liquid pool flows into the pump body through the suction port under the action of the atmospheric pressure of the pool surface, and the liquid is This is continuously sucked from the liquid pool into the cavity of the pump, and is again taken out from the water outlet of the pump, continuously flowing out of the drain pipe.
现有的潜水泵从功能来分可为清水泵和污水泵两种。The existing submersible pumps can be divided into two types: clean water pump and sewage pump.
清水泵本质是用来抽清水的（水里无杂质）所以进水口处的过滤网比较紧密，底座离开地面的高度也是比较小的，这样容易把水抽到更低的位置。清水泵的颗粒度一般要求在5MM以下，如果大于5mm就容易把网孔堵死。The purpose of the clean water pump is to extract the water (no impurities in the water), so the filter at the inlet is relatively tight, and the height of the base off the ground is relatively small, so that it is easy to pump the water to a lower position. The particle size of the clean water pump is generally required to be below 5 mm, and if it is larger than 5 mm, the mesh is easily blocked.
污水泵是用来抽比较浑浊的水，其液体里面就会有颗粒比较大的异物，所以要求这些异物能够通过泵壳且在叶轮的离心力的作用下从出水口出来，所以就需要进水口比较大，能够通过较大尺寸的异物，而且不把叶轮卡住。The sewage pump is used to pump more turbid water, and there will be relatively large foreign matter in the liquid. Therefore, it is required that the foreign matter can pass through the pump casing and exit from the water outlet under the centrifugal force of the impeller, so it is necessary to compare the water inlet. Large, able to pass large foreign objects, and does not get stuck in the impeller.
现有的清水泵和污水泵不能混淆使用，因为不但增加使用成本，而且不利于维修维护，也不利于备品备件的储备。The existing clean water pump and sewage pump can not be confused, because it not only increases the use cost, but also is not conducive to maintenance and repair, and is not conducive to the reserve of spare parts.
针对现有技术中存在的缺陷，本发明的目的在于提供一种可调节底座的水泵，采用清、污一体设计，水泵配套有可调节底座，底座能够经过简单的调节，来调节吸入口的距离，从而确定吸入物的大小。In view of the defects existing in the prior art, the object of the present invention is to provide a water pump with an adjustable base, which adopts an integrated design of cleaning and pollution, and the water pump is provided with an adjustable base, and the base can be adjusted to adjust the distance of the suction port.

以下结合附图对本发明作进一步详细说明。The invention will be further described in detail below with reference to the accompanying drawings.
如图1所示，本发明所述的可调节底座的水泵，包括：As shown in FIG. 1, the adjustable base water pump of the present invention comprises:
固定底座2，固定底座2上部设有水泵壳体4，Fixing the base 2, the upper part of the fixed base 2 is provided with a water pump housing 4,
水泵壳体4的顶部设有手柄5，并配套的设有手柄盖6，The top of the water pump housing 4 is provided with a handle 5, and a handle cover 6 is provided.
水泵壳体4内设有电机7，A motor 7 is arranged in the water pump housing 4,
所述固定底座2的上部设有用于容纳叶轮8的叶轮安装腔体11，An upper portion of the fixed base 2 is provided with an impeller mounting cavity 11 for accommodating the impeller 8.

所述固定底座2的下部设有用于容纳可旋转底座1的底座安装槽12，A lower portion of the fixed base 2 is provided with a base mounting groove 12 for receiving the rotatable base 1 .
底座安装槽12的中部设有向下延伸的底座安装凸台3，The bottom of the base mounting groove 12 is provided with a downwardly extending base mounting boss 3,
底座安装凸台3设有外螺纹，可旋转底座1从下向上旋装在底座安装凸台3上，The base mounting boss 3 is provided with an external thread, and the rotatable base 1 is screwed from the bottom to the base mounting boss 3,
底座安装凸台3沿轴向设有连通叶轮安装腔体11的腔体13，腔体13的下端即为吸入口。The base mounting boss 3 is provided with a cavity 13 communicating with the impeller mounting cavity 11 in the axial direction, and the lower end of the cavity 13 is a suction port.
本发明所述的水泵调节方法极其简单，是采用最常见的螺纹结构，调节只需左右旋转即可实现。The water pump adjusting method of the invention is extremely simple, and the most common thread structure is adopted, and the adjustment can be realized only by rotating left and right.
图1所示吸入口距离可旋转底座1下端面最远（25mm），可作为污水泵使用，The suction port shown in Figure 1 is the farthest (25mm) from the lower end of the rotatable base 1, and can be used as a sewage pump.
图2所示吸入口距离可旋转底座1下端面较近（10mm），The suction port shown in Figure 2 is closer to the lower end surface of the rotatable base 1 (10 mm).
图3所示吸入口距离可旋转底座1下端面最近（2mm），可作为清水泵使用。The suction port shown in Fig. 3 is closest to the lower end surface of the rotatable base 1 (2 mm) and can be used as a clean water pump.

During use, due to the vibration and gravity of the water pump, the threaded structure may cause the water pump to rotate, thereby causing the rotation of the rotatable base 1 to change the height of the suction port, and the rubber cushion layer may increase the rotatable base 1 and the fixed base 2 Friction between.
