Embodiment Construction
[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0031] The invention provides a vacuum pump split assembly installation method, which is based on the current situation of steelmaking multi-layer steel structure and the characteristics of the irregular shape of the vacuum pump itself. Specifically, follow the steps below:
[0032] Step 1: Construction preparation
[0033] 1) Technical preparation, before the equipment is hoisted, use 3D technology to simulate the hoisting space, the position ...

The invention discloses a split combination mounting method of a vacuum pump. The split combination mounting method comprises the steps of step I, construction preparation; step II, hoisting; and step III, welding. Compared with other traditional mounting methods, the split combination mounting method has the main beneficial effects that the normal construction progress of plant building is not influenced, the method is well linked with the construction process of steel structures, the construction steps of hoisting and after hoisting are saved, the holding time of large hoisting devices is saved, the structure of an original steel structure plant is prevented from being disassembled and damaged in a large area, in conclusion, the method causes less influence to the progress and process of the plant structure, the construction progress is quick, the utilization amount of machinery is less, the mounting manner of combination of multiple-splitting and positive-inverted mounting is adopted, the efficiency is relatively high, the investment is saved, the practical hoisting time is short, and the practicability is high.
Description
technical field [0001] The invention relates to the field of building technology, in particular to a separate assembly method for vacuum pumps in RH refining furnaces. The vacuum pumps are combined with forward and reverse installation, and are suitable for the installation of vacuum pumps in the same type of refining furnaces. Background technique [0002] With the rapid development of my country's metallurgical industry and the advancement of metallurgical technology, the requirements for steel purity are getting higher and higher, which promotes the renewal of steelmaking refining technology outside the furnace. RH, as an important way of refining outside the furnace, has dehydrogenation , decarburization, temperature compensation, uniform composition and temperature, removal of inclusions and other powerful refining functions outside the furnace have become a development trend. RH (that is, vacuum cycle degassing) system equipment is a secondary refining process equipment...
