Description
Изобретение относитс к области испытани материалов на истирание.The invention relates to the field of material abrasion testing.
Известна установка дл испытани образцов строительных материалов на износ абразивным сыпучим материалом, включающа механизм закреплени и перемещени образда и бункер дл абразивного сыпучего материала .A known apparatus for testing samples of building materials for wear with an abrasive bulk material, including a mechanism for securing and moving a specimen and a hopper for abrasive bulk material.
Предлагаема установка позвол ет варьировать виды абразивного сыпучего материала и величину давлени последнего на испытуемый образец. Достигаетс это тем, что бункер выполнен цилиндрическим с регулировочной втулкой в нижней части и снабжен пригрузочным поршнем с набором сменных грузов.The proposed setup allows varying the types of abrasive bulk material and the pressure of the latter on the sample to be tested. This is achieved by the fact that the hopper is cylindrical with an adjusting sleeve in the lower part and equipped with a loading piston with a set of interchangeable goods.
Конструкци установки по сн етс чертелюм .The design of the installation is explained in the ditch.
Установка состоит из каретки 1, в которой закрепл етс испытуемый образец, регулировочной втулки 2, бункера 3 с пригрузочным поршнем 4 и набором сменных грузов 5.The installation consists of a carriage 1 in which the test specimen is fixed, an adjustment sleeve 2, a hopper 3 with a loading piston 4 and a set of replaceable weights 5.
Механизм закреплени и перемещени образца выполнен с шатуном 6, редуктором 7 с эксцентриком, а также электродвигателем 8 и станиной 9.The mechanism for fixing and moving the sample is made with a connecting rod 6, a gearbox 7 with an eccentric, as well as an electric motor 8 and a frame 9.
Перед испытанием образец взвешивают с точностью до 0,1 г закрепл ют в каретке 1, затем в бункер 3 засыпают необходимый сыпучий материал, на который устанавливаютBefore testing, the sample is weighed with an accuracy of 0.1 g is fixed in the carriage 1, then the necessary bulk material is poured into the hopper 3, on which it is installed
поршень 4 с грузами дл создани соответствующего давлени . В зависимости от толщины испытуемого образца и крупности сыпучего материала устанавливают в нужном положении регулировочную втулку 2 и включают электродвигатель.piston 4 with weights to create an appropriate pressure. Depending on the thickness of the test sample and the size of the bulk material, set the adjusting sleeve 2 in the desired position and turn on the electric motor.
Каретка / с закрепленным в ней образцом с помощью шатунного механизма совершает возвратно-поступательное движение, а сыпучий материал, наход щийс в контакте с образцом , истирает последний. После испытани образец взвешивают вторично. По потере веса образца суд т о его сопротивл емости истпрангпо данным сыпучим материалом.The carriage / with the specimen fixed in it by means of the connecting rod mechanism reciprocates, and the bulk material in contact with the specimen abrades the latter. After testing, the sample is weighed again. According to the weight loss of the sample, it is judged on its resistance with respect to this bulk material.
