Description
(5) УСТАНОВКА ДЛЯ ИСПЫТАНИЯ ПОШХ ИЗДЕЛИЙ НА ТЕРМОСТОЙКОСТЬ(5) INSTALLATION FOR TESTING POST OF PRODUCTS FOR THERMAL RESISTANCE
1one
Изобретение относитс к испытательной технике, в частности к установкам дл испытани полых изделий на термостойкость.The invention relates to a test apparatus, in particular to installations for testing hollow articles for heat resistance.
Известна установка дл испытани полых изделий на термостойкость, содержаща две напорные магистрали дл подвода среды в полость издели , нагреватель, расположенный на одной из магистралей, холодильник, размещенный на другой магистрали, насос и средства регулировани потока среды , установленные на магистрал х lj.A known device for testing thermal resistance of hollow products, comprising two pressure lines for supplying the medium to the product cavity, a heater located on one of the lines, a refrigerator placed on the other line, a pump and means for controlling the flow of the medium installed on the lines lj.
Недостатком установки вл етс низка точность испытаний, обусловленна тепловой инерцией установки и испытуемого издели , а также потер ми тепла в окружающую среду.The disadvantage of the installation is the low accuracy of the tests, due to the thermal inertia of the installation and the product under test, as well as the loss of heat to the environment.
Цель изобретени - повышение точности испытани путём уменьшени тепловой инерции установки.The purpose of the invention is to improve the accuracy of testing by reducing the thermal inertia of the installation.
Указанна цель достигаетс тем, что установка дл испытани полых изделий на термостойкость, содержащем две напорные магистрали дл подвода среды в полость издели , нагреватель , расположенный на сдной из магистралей, холодильник, размеи|енный на другой магистрали, насос и средства регулировани потока среды, установленные на магистрал х, снаб-: женасмесительной емкостью дл отвода среды из издели и двум ,0 нительными трубопроводами, соединенными с соответствующими магистрал ми за нагревателем и холодильником в направлении потока среды и со смесительной емкостью.This goal is achieved by the fact that the installation for testing hollow products for heat resistance, containing two pressure lines for supplying the medium to the cavity of the product, a heater located on the bed of the lines, a refrigerator spaced on another line, a pump and means for controlling the flow of the medium on the mains, equipped with: a mixing chamber for draining the medium from the product and two, 0 pipelines connected to the respective mains behind the heater and cooler in the direction of flow environment and with mixing capacity.
Кроме того, она снабжена двум до полнитепьными трубопроводами, соедин ющими смесительную емкость с входом напорных магистралей, и дополнительными нагревателем и холодильником , установленными на соответствующих трубопроводах.In addition, it is equipped with two up to half a half pipelines connecting the mixing tank to the entrance of pressure lines, and an additional heater and cooler installed on the respective pipelines.
