Settler maintenance method

The invention discloses a settler maintenance method, which relates to the technical field of refining and chemical large-scale equipment maintenance process, and comprises the following steps: step 1, prefabricating at an early stage, step 2, dismounting and hoisting, and step 3, mounting and hoisting. According to the method, the settler of the oil refining production device can be overhauled more quickly and better, the overhauling quality is ensured, the overhauling period is shortened, the cost and the labor intensity are further reduced, and the method is mainly achieved through early-stage prefabrication, dismantling and hoisting and installing and hoisting. 本发明公开了一种沉降器检修方法，涉及炼化大型设备检修工艺技术领域，包括步骤一、前期预制，步骤二、拆除吊运，步骤三、安装吊运；本发明更快更好的检修炼油生产装置沉降器，确保检修质量、缩减检修工期，进一步降低成本和劳动强度，主要通过前期预制、拆除吊运、安装吊运三大骤来实现。
