Description

采用中央处理设备的浸没式抽水装置
技术领域
本发明涉及一种抽水装置，特别是一种浸没式抽水装置。
背景技术
潜水泵是是深井提水的重要装置，被广泛的使用于工农业。
一般来讲，根据排水原理可将水泵分为：一、叶轮式泵，如：离心泵、混流泵、轴流泵等、旋流泵；二、容积泵，如：柱塞泵、齿轮泵、螺杆泵、叶片泵等；三、其他类型，如：射流泵、水锤泵等。
螺杆泵属于容积泵，扬程高单流量少，特别适合与疏松粘稠液体。当螺杆高速旋转时，后端轴承受到较大压力，加速磨损，同时也限制了螺杆泵的转速。轴承所受压力主要来自于螺杆的反作用力，而对于一台螺杆潜水泵而言，该反作用力主要由转速和出口端压力决定。当需要高转速时，理想的解决办法是降低出口端的压力来实现。然而，面对大扬程的需求，降低出口端压力成为了难题。
发明内容
本发明的目的在于：克服上述现有技术的缺陷，提出一种浸没式抽水装置。
为了达到上述目的，本发明提出的浸没式抽水装置，包括具有螺杆腔体的壳体，设置于螺杆腔体内的一组螺杆，所述螺杆下端连接有进水道，上端连接有出水道，螺杆轴前后两端由轴承支撑，螺杆轴通过传动机构联接第一电机，其特征在于：所述出水道的入水段具有鼓形腔室，鼓形腔室内安装有受第二电机驱动的叶轮，鼓形腔室的入水口呈水平放置，鼓形腔室出水口呈竖直放置，与鼓形腔室相连的出水道具有螺旋形结构；与鼓形腔室相连的出水道内插入有吹气管，所述吹气管的吹气方向朝向鼓形腔室的入水口，吹气管上端连接气泵；所述螺杆轴后端的壳体上设置有调压腔，所述螺杆轴后端插入该调压腔内，调压腔与螺杆轴的间隙处嵌入有密封填料，调压腔通过管路相连有液压油泵，所述螺杆腔体的下端和上端分别设有用于监测水压的压力传感器。
本发明浸没式抽水装置，进一步的改进在于：
1、所述出水道的入水段呈喇叭形，进水侧口小，出水侧口大。
2、所述叶轮为具有7个叶片。
3、与所述鼓形腔室出水口相连的出水道与水平面的夹角为70-90°。
4、所述进水道的内壁具有螺旋形结构。
5、所述吹气管的出气口位于出水道中心位置。
6、所述管路上设置有缓冲腔室，所述缓冲腔室的体积不低于调压腔总体积的10倍。
7、所述缓冲腔室靠近环形槽一端设置。
8、所述压力传感器的信号输出端连接中央处理设备。
一方面，本发明在螺杆泵的出水口设置有叶轮式水泵和吹气管，通过叶轮式水泵和气泵的工作，一定程度上降低了螺杆泵出水口处的压力；另一方面，本发明可通过采集螺杆腔体的下端处和上端处的水压，来获取应当向调压腔输入的压力，通过调整该输入压力，将螺杆轴向上推，来对抗螺杆所受到的强大的后坐力。两方面结合，降低螺杆轴所受对的反作用力，从而降低轴承的载荷，降低轴承的磨损，延长潜水泵的使用寿命，以及为进一步提高螺杆泵转速提供了保障。
从吹气管吹入的气流在螺旋形的水流的中央位置，夹杂着水向前冲，从而为水流提供了更强劲的冲力，更进一步降低螺杆泵出水端的压力。
本发明在螺杆泵的进水到和出水道都进行螺旋形处理，使进入水流更规整，降低阻力，提高抽水效率。出水口设计成喇叭口形状，能够进一步降低出水端的压力。靠近环形槽一端设置缓冲腔室能够降低环形槽输出水流的高速抖动，确保调压腔内具备较稳定的压强，杜绝轴承抖动的发生。
