(54) СПОСОБ ИЗГОТОВЛЕНИЯ ТРУБНЫХ РЕШЕТОК ДЛЯ ТЕПЛООБМЕННЫХ АППАРАТОВ(54) METHOD OF MANUFACTURING PIPE LATTICES FOR HEAT EXCHANGE EQUIPMENT
(57) Использование изобретени позвол ет повысить надежность соединени труб с решеткой . Вначале на концевых участках труб выполн ют сферические углублени , расположенные в шахматном пор дке. Затем формируют трубный пучок и устанавливают его в специальную форму. Форму заполн ют расплавленным металлом до уровн , превышающего высоту двух р дов углублени , и осуществл ют охлаждение расплава. 1 ил.(57) The use of the invention makes it possible to increase the reliability of the connection of pipes with a grate. First, spherical recesses, arranged in a checkerboard pattern, are made at the end sections of the pipes. Then form a tube bundle and set it in a special form. The mold is filled with molten metal to a level greater than the height of two rows of depressions, and the melt is cooled. 1 il.
Изобретение относитс к теплообмен- ным аппаратам и может быть использовано в различных отрасл х промышленности.The invention relates to heat exchangers and can be used in various industries.
Целью изобретени вл етс повышение надежности соединени труб с решеткой .The aim of the invention is to increase the reliability of the connection of the pipe to the grate.
На чертеже изображена сборка пучка теплообменных труб с трубными решетками , изгоювленными описываемым способом .The drawing shows the Assembly of the bundle of heat exchange tubes with tube grids, izgoyulennymi described method.
Сборка содержит теплообменные трубы 1 с концевыми участками, на которых выполнены сферические углублени 2, расположенные в шахматном пор дке. Концы труб 1 сформированного пучка закреплены в трубной решетке 3, образованной из охлажденного металла или резины.The assembly comprises heat exchange tubes 1 with end sections on which spherical recesses 2 are made, arranged in a checkerboard pattern. The ends of the tubes 1 of the formed beam are fixed in a tube sheet 3 formed from cooled metal or rubber.
Способ изготовлени трубных решеток заключаетс в следующем.A method of manufacturing tube sheets is as follows.
Вначале на концевых участках труб 1 выполн ют сферические углублени , расположенные в шахматном пор дке. Затем с помощью дистанционирующих решетокFirst, spherical recesses are arranged at the end sections of the pipes 1, arranged in a checkerboard pattern. Then using spacer grids
формируетс трубный пучок, который устанавливают в форму и закрепл ют специаль- ным крепежом. После этого форму заполн ют расплавленным металлом до уровн , превышающего высоту двух р дов углублений, и осуществл ют охлаждение расплава. В качестве материала расплава может быть использована резина.a tube bundle is formed, which is placed in a mold and secured with special fasteners. Thereafter, the mold is filled with the molten metal to a level greater than the height of two rows of recesses, and the melt is cooled. Rubber can be used as a melt material.
Использование изобретени позвол ет повысить герметичность соединени труб с трубной решеткой, исключить радиальные повороты труб вокруг их оси и снизить трудоемкость изготовлени трубных решеток.The use of the invention makes it possible to increase the tightness of the connection of pipes with a tube sheet, to eliminate radial turns of pipes around their axis, and to reduce the laboriousness of manufacturing tube sheets.
