Abstract

The present invention refers to a leakageless water pump in which the rotation of the motor is transmitted to the impeller by means of a pair of plates on which magnets are equipped. A partition is mounted in the casing of the pump to separate the pair of blades with each other. One one side of the partition is the rotating motor axle on which one of the pair of plates is fixed. On the other side of the partition is a stationary axle on which the other plate integral with the impeller is freely rotatable supported. The pump can be used in a car to eliminate the leakage of the water and to prolong the life of the pump.

Description

由永磁联轴节传动的不泄漏水泵 技术领域  Non-leakage water pump driven by permanent magnet coupling
本发明涉及一种水泵， 特别是一种由永磁联轴节传动的不泄漏汽 车水泵。 背景技术  The invention relates to a water pump, in particular to a non-leaking automobile water pump driven by a permanent magnet coupling. Background technique
已有技术的水泵的典型结构如图 2 所示。 其中 21 为皮带轮， 由 汽车发动机通过皮带拖动而旋转。 皮带轮 21 的运动通过轴 22传递给 水泵叶轮 25。 叶轮 25 旋转便完成泵水操作， 使水流沿图 2 中箭头所 示的方向流动。 图中 24为密封结构， 它的作用是防止水流侵入轴承 23 所在区域， 以免进一步越过轴承 23而顺轴 22从皮带轮 21下方漏出。 图中 26 为水泵壳体。 事实上， 密封结构 24与轴 22之间必须留有空 隙， 否则轴 22便被抱死而无法转动； 另一方面， 密封结构 24又经常 受到高速旋转的轴 22 的磨损， 使轴 22与密封结构 24之间的间隙越 来越大， 致使水流通过间隙漏入轴承 23所在区域， 进而顺轴 22在皮 带轮 21 下方漏出水泵壳体成为不可避免的问题， 只是泄漏或多或少 而已。 水流进入轴承 23将使轴承 23锈蚀， 加速整个水泵的报废； 同 时较多的水从泵壳漏出， 将使水箱中水的保有量很快减少， 使汽车水 冷却系统性能下降， 形成频繁停车上水或危害汽车运行的后果。 上述 缺点是已有技术水泵的结构原理本身带来的， 虽可通过改进密封填充 结构来改善， 但不能根本解决问题。 发明概述  The typical structure of the prior art water pump is shown in Figure 2. 21 is a pulley, which is rotated by the car engine by dragging the belt. The movement of the pulley 21 is transmitted to the water pump impeller 25 through the shaft 22. The impeller 25 rotates to complete the pumping operation, so that the water flow flows in the direction indicated by the arrow in FIG. 2. 24 is a sealing structure in the figure, and its function is to prevent water from entering the area where the bearing 23 is located, so as to prevent the shaft 22 from passing over the bearing 23 and leaking out from below the pulley 21. In the figure, 26 is the pump casing. In fact, there must be a gap between the sealing structure 24 and the shaft 22, otherwise the shaft 22 will be locked and unable to rotate; on the other hand, the sealing structure 24 is often subject to wear of the shaft 22 rotating at high speed, which causes the shaft 22 and the seal to be sealed. The gap between the structures 24 is getting larger and larger, causing water to leak into the area of the bearing 23 through the gap, and the leakage of the pump housing under the pulley 21 along the shaft 22 becomes an inevitable problem, but the leakage is more or less. Water entering the bearing 23 will cause the bearing 23 to rust and accelerate the scrapping of the entire pump. At the same time, more water leaks from the pump casing, which will quickly reduce the amount of water in the water tank, reduce the performance of the car's water cooling system, and cause frequent parking Consequences of water or hazardous vehicle operation. The above-mentioned disadvantages are brought about by the structural principle of the prior art water pump. Although it can be improved by improving the seal filling structure, the problem cannot be solved fundamentally. Summary of invention

以下结合附图对本发明作进一步阐述。 如图 1 所示， 本发明的水 泵包括泵壳体 18， 转轴 12， 平板式永磁联轴节， 水泵叶轮 15和静止 轴 19。 泵壳体 18中设有中隔 17， 转轴 12和静止轴 19分处中隔的两 侧， 中隔 17 的存在使水泵中的水流沿图 1 中箭头所示的方向流动， 因此水流存在的部位和转轴 12、 轴承 13 完全隔开， 使水流不再有顺 着旋转轴漏出泵壳之可能。 平板式永磁联轴节由主动磁盘 14 和从动 磁盘 16组成， 它们分别置于中隔 17 的两边。 主动磁盘 14和从动磁 盘 16 是完全相同的两块磁盘， 两磁盘装有磁块的表面互相面对。 主 动磁盘 14和转轴 12相连， 从动磁盘 16和水泵叶轮 15机械上同轴线 且连在一起。 发动机通过皮带带动皮带轮 1 1 旋转， 此旋转运动及其 携带的功率， 通过转轴 12、 平板式永磁联轴节的主动磁盘 14， 隔着 中隔 17， 由磁场作媒介传递给平板式永磁联轴节的从动磁盘 16。 从 动磁盘 16的旋转带动水泵叶轮 15旋转， 完成泵水操作。 水泵叶轮 15 与静止轴 19 之间有水润滑滑动轴承 20 (见图 4 ) ， 通过水润滑滑动 轴承 20套在轴 19上。 此轴承 20不但提供水泵叶轮 15旋转所需的径 向约束， 还通过轴头 10提供轴向约束以防止水泵叶轮 15沿静止轴 19 上窜 （见图 4) 。 静止轴 19和转轴 12不同， 是不旋转的， 它的下端 固定在泵壳 18上。 当泵壳体 18由非铁磁材料铸成时， 中隔 17是泵体的有机组成部 分， 否则， 中隔 17 的材质应选用非铁磁金属材料或高分子非金属材 料。 如图 3所示， 本发明所使用的平板式永磁联轴节的主动磁盘和从 动磁盘是结构和尺寸完全一致的一对磁盘。 就一只磁盘而言， 它由铁 质圆盘 31和布置在铁质圆盘 31—侧的圆形表面上的若干个永磁块 32 所组成。 所述永磁块 32 为偶数， 沿圆形表面的周向排成一个圆环， 并磁化为 N、 S 相间极性。 相邻磁块之间可以有缝隙存在， 也可以紧 贴。 图 4 表示了水泵叶轮、 静止轴及水润滑滑动轴承之间的相互关 系， 其中 20为水润滑滑动轴承， 15为水泵叶轮， 19为静止轴， 10为 轴头， 18为泵壳体。 本发明的优点： 由于本发明采用了可超距传递运动和功率的永磁 联轴节， 故可以在泵体中将水流部分和传动部分完全隔开， 当用于汽 车时， 从根本上消除了汽车水泵漏水问题， 大大提高水泵工作寿命， 使汽车水箱中的冷却液不流失， 保障发动机在正常温度下运行， 从而 使汽车的运行更为完全可靠。 The present invention is further explained below with reference to the drawings. As shown in FIG. 1, the water pump of the present invention includes a pump housing 18, a rotating shaft 12, a flat-plate permanent magnet coupling, a water pump impeller 15, and a stationary shaft 19. The pump casing 18 is provided with a septum 17, the rotating shaft 12 and the stationary shaft 19 are separated at two sides of the septum. The presence of the septum 17 causes the water flow in the pump to flow in the direction shown by the arrow in FIG. The part is completely separated from the rotating shaft 12, the bearing 13, so that the water flow can no longer leak out of the pump casing along the rotating shaft. Plate type permanent magnet coupling driven by drive disk 14 and driven The magnetic disk 16 is composed of them, which are respectively placed on both sides of the septum 17. The driving magnetic disk 14 and the driven magnetic disk 16 are identical two magnetic disks, and the surfaces on which the magnetic disks are mounted face each other. The driving magnetic disk 14 is connected to the rotating shaft 12, and the driven magnetic disk 16 and the pump impeller 15 are mechanically coaxial and connected together. The engine drives the pulley 1 1 to rotate through the belt. This rotational movement and the power it carries are transmitted to the plate-type permanent magnet by the magnetic field as the medium through the septum 17 and the active magnetic disk 14 of the plate-type permanent magnet coupling. The driven disk 16 of the coupling. The rotation of the driven magnetic disk 16 drives the water pump impeller 15 to rotate to complete the pumping operation. There is a water-lubricated sliding bearing 20 (see FIG. 4) between the water pump impeller 15 and the stationary shaft 19. The water-lubricated sliding bearing 20 is sleeved on the shaft 19. This bearing 20 not only provides the radial restraint required for the rotation of the pump impeller 15, but also provides the axial restraint through the shaft head 10 to prevent the pump impeller 15 from running along the stationary shaft 19 (see FIG. 4). Unlike the rotating shaft 12, the stationary shaft 19 is non-rotating, and its lower end is fixed to the pump casing 18. When the pump casing 18 is cast from a non-ferromagnetic material, the septum 17 is an organic component of the pump body; otherwise, the material of the septum 17 should be a non-ferromagnetic metal material or a polymer non-metal material. As shown in FIG. 3, the driving magnetic disk and the driven magnetic disk of the flat-type permanent magnet coupling used in the present invention are a pair of magnetic disks with completely identical structures and sizes. As far as a magnetic disk is concerned, it is composed of an iron disk 31 and a plurality of permanent magnet blocks 32 arranged on a circular surface on one side of the iron disk 31. The permanent magnet blocks 32 are even numbers, are arranged in a circle along the circumferential direction of the circular surface, and are magnetized to N, S phase polarity. There can be gaps between adjacent magnetic blocks, or they can be close to each other. Figure 4 shows the relationship between the water pump impeller, the stationary shaft, and the water-lubricated sliding bearing. 20 is a water-lubricated sliding bearing, 15 is a water pump impeller, 19 is a stationary shaft, 10 is a shaft head, and 18 is a pump housing. Advantages of the present invention: Because the present invention uses a permanent magnet coupling that can transmit motion and power at an excessive distance, the water flow part and the transmission part can be completely separated in the pump body. When the car is running, the problem of water leakage from the water pump of the car is fundamentally eliminated, the working life of the water pump is greatly improved, the coolant in the water tank of the car is not lost, and the engine is operated at normal temperature, so that the operation of the car is more completely reliable.
