技术介绍
重型多级离心泵的应用范围遍及煤矿、石油、钢厂、国防、农业和化工生产等各个领域,其使用量很大。抽取介质含有大量的固体颗粒,导致泵的使用寿命非常低,一般2~3个月就要进行大修。以矿井中最常用的重型多级离心泵为例,工作时泵体中的压力很大,为了使各轴段紧密的联系在一起,需要使用规格很大的穿杠螺栓连接才能提供泵体工作时所需的预紧力要求。用传统的人力方法进行拆装时,不仅劳动强度大,作业效率低,成本高,而且由于剧烈振动的影响,在施工过程中还有可能损伤毗邻的零部件,甚至影响和破坏原来结构的力学平衡;同时也难以根据设计要求准确控制装配力矩。为了提高多级离心泵组装与拆卸的速度,减少水泵维修与保养时间,并控制螺栓连接的预紧力要能够达到一定的工作要求,把工人从高强度的体力劳动中解放出来,要求设计并制造出一种适用于多级离心泵穿杠螺栓连接这一特殊结构的拧紧与拆卸的配套装置。由于多级离心泵承担了矿井中主要的排水任务,工作时间长,环境恶劣,而排出的水质中所含的固体颗粒多,加上流水的冲刷叶轮和导叶非常容易锈蚀和磨损。为了保证矿井工作环境的安全,一般矿井中都有多个水泵轮流工作,大量的水泵需要检修。穿杠螺栓连接是否可靠将直接关系到多级离心泵效率的高低,为了提高装卸效率保证穿杠螺栓连接的可靠性,必然需要使用较大的紧固和拆卸力矩对离心泵穿杠螺栓进行的装卸。穿杠螺栓的装卸方法主要有手动装卸、起重机进行装卸、电动装置进行装卸和液压装置进行装卸,其中液压装置进行装卸是最好的方法。液压扳手在日本、美国、德国等 ...
