Abstract
The invention discloses a manufacturing technological method for a turbonator auxiliary engine sealing oil device. The manufacturing technological method is capable of ensuring the quality and saving the cost and the production cycle. An oil pump, a cooler and an oil sealing box are arranged on a bottom plate, the oil pump is taken as a starting point and is connected with a pipeline, after the connection is finished, the pipeline is dismantled, and pressure test is performed; the pipeline is cleaned with acid based on a special file, and gas phase anti-rust oil is poured into the pipeline, an end opening is sealed, and the outer surface of the pipeline is painted, so that rusting is prevented. The oil pump, the cooler, a filter, the oil sealing box and the pipeline are reinstalled, and an instrument board is arranged on the bottom plate. After the comprehensive test is finished, the gas phase anti-rust oil is poured into the sealing oil device. The manufacturing technological method is applied to manufacturing the sealing oil device, so that the production efficiency is improved, the manpower is saved, the production cycle is saved, the method has greater significance that the product stability is good, and the quality is improved.
Description
Technical field:
The present invention relates to a kind of process for machining and manufacturing of steam turbine generator sealing oil device.
Background technique:
In the manufacturing process of steam turbine generator sealing oil device in the past, occur the interference problem of component in pipeline, occur the corrosion problem of pipeline, pipeline poorly sealed, product is short for working life at the scene.
Summary of the invention:
The invention provides a kind of guarantee to improve the quality of products, save the method for manufacturing technology of cost and a kind of steam turbine generator sealing oil device of manufacture cycle.Technological scheme of the present invention is: 1) place base plate: be placed on by base plate on the operating platform of level; 2) critical piece is installed: be installed on base plate by oil pump, cooler, oil seal housing by drawing; 3) welding point is assembled: take oil pump as starting point, start connecting pipeline, and pipeline is connected by a point flange threaded fastener for assembling end points, point assembly parts that assembling is welded together by drawing by flange, pipe fitting, valve; 4) divide the leakage of assembling and pressure test: disassembled by pipeline, carry out pressure test to a point assembling, pressure is 1.2MPa, within 15 minutes, does not reveal; 5) surface treatment: carry out pickling to a point assembling according to special carbon steel pickling technique rules, then pour into volatile rust preventive oil in pipe fitting, seals a point assembling port flange, paints, prevent carbon steel pipeline from getting rusty to a point outer surface for assembling; 6) general assembly: oil pump, cooler, filter, oil seal housing, packing are joined and reinstalls on base plate, then instrument panel is installed on base plate by drawing; 7) antirust treatment: after combined test is finished, pours into volatile rust preventive oil in the sealing oil device of carbon steel, prepares delivery.
The present invention has fundamentally reformed the manufacturing technology of steam turbine generator sealing oil device, is the change of essence in manufacture method.Use technological method of the present invention, make do not have the operator of working experience successfully can complete the assembling work of sealing oil device, and ensure the quality of product.
The present invention uses in the manufacturing of sealing oil device, and manufacturing efficiency greatly improves, and has not only saved cost of human resources, has saved the manufacturing cycle, and larger value is the raising of product stability, and quality obviously promotes.
