Description

一种钻井液砂泵
技术领域
本发明涉及石油钻井液砂泵领域,尤其是涉及一种钻井液砂泵。
背景技术
离心式砂泵主要是用来给油田钻机的循环固控系统配套,其作用是给除砂器、除泥器、混料器等提供具有一定排量和压力的钻井液,以保证这些设备高效工作。在现有的技术中,砂泵的工作环境极为恶劣,长期泵送大量含砂液体,因此要求轴端的密封非常可靠,很难用一般泵的密封方法解决。同时,由于介质不但有研磨性,而且有腐蚀性,所以泵内也常遭到破坏,由于密封失效率高,导致传送轴磨损,存在泵轴的使用寿命短等技术问题,以前采用的手段为更换整跟泵轴,费用较高且造成不必要的浪费。
发明内容
有鉴于此,本发明提供一种结构简单、使用方便、维修保养费用较低的一种钻井液砂泵。
为实现上述目的,本发明提供了一种钻井液砂泵,包括底座、泵壳、泵座,所述底座上两端固设有固定板,所述泵壳固设在左侧的所述固定板上,所述泵座固设在两个所述固定板之间,所述泵座通过两侧的轴承和带油封的轴承压板在其内设置有泵轴,所述泵轴的右端设置有安装键,所述泵轴的左端经过填料箱与所述泵壳内的叶轮相连接,所述泵轴位于所述填料箱的位置上设置有轴套,所述泵座在左侧的所述轴承压板外设置有挡泥板。
更进一步,所述泵壳为圆壳泵机构。
更进一步,所述叶轮的叶面为开式大宽度柱面。
更进一步,所述泵轴采用平衡压力型机械密封。
本发明具有的优点和积极效果是:结构简单、使用方便、维修保养费用较低。
附图说明

具体实施方式
如图1、图2所示,本发明包括底座1、泵壳2、泵座3,所述底座1上两端固设有固定板4,所述泵壳2固设在左侧的所述固定板4上,所述泵座3固设在两个所述固定板4之间,所述泵座3通过两侧的轴承和带油封的轴承压板5在其内设置有泵轴6,所述泵轴6的右端设置有安装键7,所述泵轴6的左端经过填料箱8与所述泵壳2内的叶轮相连接,所述泵轴6位于所述填料箱8的位置上设置有轴套9,所述泵座3在左侧的所述轴承压板5外设置有挡泥板10。
所述泵壳2为圆壳泵机构。
所述叶轮的叶面为开式大宽度柱面。
所述泵轴6采用平衡压力型机械密封。
以上所述仅为本发明的较佳实施例而已,并不用以限制本发明,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围之内。
