(54) СПОСОБ УПЛОТНЕНИЯ ТРУБ В ТЕПЛООБМЕННИКЕ(54) METHOD OF SEALING PIPES IN HEAT EXCHANGER
1one
Изобретение относитс к способам уплотнени труб в теплообменниках с вальцовочным соединением.This invention relates to methods for sealing pipes in heat exchangers with a rolling compound.
По основному авт.св. № 629436 известен способ уплотнени труб в теплообменнике , заключающийс в заливке в полость между трубными досками полимерного материала и выдержки его при избыточном давлении в течение времени, составл ющего 50-80% от времени полимеризации полимерного материала 1 .According to the main auth. No. 629436, a method of sealing pipes in a heat exchanger is known, which consists in pouring a polymer material into the cavity between the tube plates and holding it under an overpressure for a time of 50-80% of the polymerisation time of the polymer material 1.
Недостаток известного способа длительность времени полимеризации.The disadvantage of this method is the duration of polymerization time.
Цель изобретени - сокращение времени полимеризации.The purpose of the invention is to reduce the polymerization time.
Указанна цель достигаетс тем, что согласно способу уплотнени труб в теплообменнике выдержку осуществл ют путем подачи в трубы теплообменника насыщенного пара с температурой 140-1600С.This goal is achieved by the fact that according to the method of sealing pipes in the heat exchanger, the exposure is carried out by supplying saturated steam with a temperature of 140-1600 ° C to the heat exchanger pipes.
Способ осуществл етс следующим образом.The method is carried out as follows.
В полость между трубными досками заливают полимерный материал, например бакелитовый лак, который, выдерживают при избыточном давлении с од-, новременной подачей в трубки теплообменника насыщенного пара при температуре 140-160°С. Затем давление в полости снижают.A polymer material is poured into the cavity between the tube plates, for example, bakelite lacquer, which is maintained at an overpressure with a single-time supply of saturated steam into the heat exchanger tubes at a temperature of 140-160 ° C. Then the pressure in the cavity is reduced.
Подача пара при температуре ниже 140°С нерациональна, так как в этом случае врем полимеризации уменьшаетс незначительно, а температура выше 1600с нежелательна из-за большого давлени пара в трубках, The steam supply at a temperature below 140 ° C is irrational, since in this case the polymerization time decreases slightly, and the temperature above 1600 s is undesirable due to the high vapor pressure in the tubes,
10 что южёт привести к аварийной ситуации .10 that leads to an emergency.
Применение предлагаемого способа уплотнени труб в теплообменнике позвол ет сократить врем полимеризации The application of the proposed method of sealing pipes in a heat exchanger reduces the time of polymerization
15 с 16 до 6 ч., т.е. в 2,7 раза.15 from 16 to 6 am, i.e. by 2.7 times.
