The invention relates to the technical field of mechanical equipment manufacturing, in particular to a pump station non-stop overhauling device which comprises two parallel pump sets, a storage box is arranged at the bottoms of the two parallel pump sets, the two parallel pump sets comprise first-stage small pumps and second-stage large pumps respectively, the first-stage small pumps comprise the first small pump and the second small pump, and the second-stage large pumps comprise the first large pump and the second large pump; an isolation maintenance mechanism is arranged in the storage box, the position of the isolation maintenance mechanism corresponds to the position of the parallel pump set, the isolation maintenance mechanism comprises a floating box, and a pressurization valve and a release valve are arranged on the two sides of the bottom of the floating box respectively. According to the invention, the interior of the pump set is designed into two sets of pump sets connected in parallel, during the maintenance of one pump in the pump set, a system for maintaining the pump is sealed through the designed maintenance isolation device, and then the target pump is subjected to isolation maintenance, so that the normal work of the other pump set is not influenced, and 50% of functions of the whole pump set are ensured; therefore, the purpose of maintenance without shutdown is achieved.

    本发明涉及机械设备制造技术领域,具体为一种泵站不停机检修装置,包括两组并联泵组,两组并联泵组的底部设置有存储箱,两组并联泵组分别包括一级小泵与二级大泵,一级小泵包括小泵一与小泵二,二级大泵包括大泵一与大泵二;存储箱的内部设置有隔离检修机构,隔离检修机构的位置与并联泵组的位置相互对应,隔离检修机构包括浮箱,浮箱的底部两侧分别设置有加压阀与泄放阀。本发明内,泵组内部设计为两组并联泵组,泵组中的一个泵检修期间,通过设计的检修隔离装置将检修泵的系统进行密封,然后对目标泵进行隔离检修,这样就不影响另一路泵组的正常工作,确保整体泵组保持50%功能,从而实现不停机进行检修的目的。
