Description

一种水泵 技术领域
本发明属于泵领域，具体涉及一种水泵。
背景技术
水泵利用自然能源或借动力设备和传动装置将水由低处升至高处的水力机械装置，广泛应用于农田灌溉、排水以及农牧业、城镇供水、工矿企业、排水等方面。日常的农田灌溉、或一般的家庭排水，用的大都是活塞泵和离心泵，特别是离心泵，在工业或农业的各个领域的应用非常广。离心泵结构简单而紧凑，对于同一输送量，离心泵所占面积小，重量轻，材料耗用较少，对基础要求无住复泵高，可高速运行，可以采取2极或4极电动机直联，传动结构简单易安装，离心泵的这些优势深受大众的喜爱。但离心泵有个不太好的特性，就是在运行前，要先灌满水，而且当今的水泵能耗还是稍显高，有些水泵的噪音很大，长时间工作让人身心难受，不利健康。
发明内容
本发明解决的问题是提出一种水泵。
一种水泵，其特征在于：包括动能装置、轴承、固定装置、排水管、壳体；动能装置通过联轴装置和轴承的一端连接，轴承穿透固定装置并和固定装置固定相接，排水管置于固定装置上，排水管上下两端的半径大小不一样，轴承、固定装置、排水管全都置于所述壳体内。
进一步地，所述固定装置圆柱体形状设置。
进一步地，所述固定装置开有贯穿整个固定装置的孔洞。
进一步地，所述排水管底端半径比顶端半径小设置。
进一步地，所述排水管顶端面为倾斜面设置。
进一步地，所述排水管底端半径比顶端半径小，且顶端的端面为倾斜面设置。
进一步地，所述排水管可以和所述孔洞相贴合。
进一步地，所述壳体的顶部设置有可拆装的盖体。
进一步地，所述盖体内部海螺形状设置。
一种流体传输装置，其特征在于：包括权利要求1-9所述的一种水泵。
本发明的有益效果是：本发明利用电机的动能打破排水管两端的气压平衡，常压下的气压变成高气压的一端，气压把水压入排水管流向气压低的一端，从而形成对水的输送，本发明结构简单，不用叶轮带动水往前压，节约了能耗，启动前也不用灌满水。

具体实施方式
以下通过实施例进一步说明本发明，但不作为对本发明的限制。下列实施例中未注明的具体实验条件和方法，所采用的技术手段通常为本领域技术人员所熟知的常规手段。
实施方式1
如图1图2，一种水泵，其特征在于：包括动能装置1、轴承2、固定装置3、排水管4、壳体5；所述动能装置1通过联轴装置11和所述轴承2的一端连接，所述轴承2随着所述动能装置1的启动而转动，所述轴承2贯穿所述固定装置3并和所述固定装置3固定相接，所述轴承2转动的时候所述固定装置3也同步跟着转动，所述固定装置3圆柱体形状设置，可以减少所述固定装置3在转动时受到的阻力；所述固定装置3开有贯穿整个固定装置3的孔洞31，所述孔洞31至少开有一个，具体多少看情况而定，所述孔洞31上下两端口的半径大小可根据所述排水管4的形状而做设置。所述排水管4可底端半径比顶端半径小设置(如图3)，也可在所述排水管两端半径大小一致时顶端面为倾斜面设置(如图4)；或者所述排水管4底端半径比顶端半径小设置时顶端面为倾斜面设置(如图5)。所述排水管4置于所述固定装置3上，所述排水管4可以和所述孔洞31相贴合，所述排水管4被所述所述固定装置3固定住，在旋转的过程中部会被甩出去。所述排水管4至少有两根，所述排水管4的数量跟所述孔洞31的数量相同。所述排水管4上下两个端面的面积大小不一样，只有两端的面积大小不一样，在旋转的时候才会产生压力差(产生压力差的原理是：当排水管静止时，在没有外力做用下，排水管的两个端面的流体压强是相等的；当排水管做圆周运动时，因为两个端面运动的角速度一样，而面积大的端面线速度更快，所以，依据伯努利原理，面积大的端面压强会更低，故产生压力差)；所述排水管4端面面积小的一端为跟水接触的一端。所述轴承2、所述固定装置3、所述排水管4全都置于所述壳体内，形成一个完整的装置；所述壳体5的顶部设置有可拆装的盖体51，可适应不同环境的需求，所述盖体51内部海螺形状设置，所述排水管4喷出的水直接拍打到所述盖体51海螺形状内壁上，减少了力的相互作用，从而提高水的传送速度。
工作原理：当动能装置启动时，轴承也跟着转动，和轴承固定相接的固定装置以及和固定装置的孔洞相贴合的排水管也都跟着同步转动，排水管半径较小的一端是伸入水里的，在高速旋转过程中，排水管半 径较大的一端的气压会逐渐低于大气压，水受到大气压的作用下会向气压低的方向流动，从而完成抽水的过程。
实施方式2
实施方式2和实施方式1区别的地方在于三种排水管的选择。
以上所述，仅为本发明的具体实施方式。但本发明的保护范围并不局限于此，任何不经过创造性劳动想到的变化或简单替换，都应该涵盖在本发明的保护范围之内。
