Description

Известен прибор дл  определени  газопроницаемости формовочных земель, основанный на нродуванип воздуха через цилиндрические образцы из приготовлеиной смеси, результат испытани  которых не соответствуют истинной величине газопроницаемости оболочковых форм. Кроме того, врем  проведени  испытани  таким методом довольно продолжительное - 60-90 мин.A device is known for determining the gas permeability of molding lands, based on the production of air through cylindrical specimens from a prepared mixture, the test result of which does not correspond to the true gas permeability of the shell molds. In addition, the test time by this method is rather long - 60-90 minutes.

Предлагае.мое устройство вьшолнено в виде металлического колпачка с резиновым уилотнением, соединенного с помощью резиновых шлангов со стандартным прибором дл  определени  газонепроницаемости устран ет опггсаниые недостаткиНа чертеже представлено предлагаемое устройство, которое состоит из металлического колпачка / с кольцевым резиновым уплотнением 2, на штуцеры которого надеты два м гкпх резиновых шланга; один из них соединен с патру бко:, идущим к вод ному монометру прибора дл  определени  газопроницаемости марки 0,42, а вторй е помощью щтуцера соединен ниппелем Ф ,Ь мм, ввернутым в гнездо загвора этого же прибораМетодика испытани  заключаетс  в следующемНа гладкую поверхность оболочки накладывают колпачок /, который прижимаетс  резиновым уплотнением, к оболочке рукой ИоТИ специальной струбциной. Поворотом крана прибора в положение «испытание при опускании колокола фиксируют показание манометра. Затем штангелем замер ют толщину оболочки в месте определени  газопроницаемости и по таблице перевод т показани  манометра в единицы газопроницаемостиThe proposed device is made in the form of a metal rubber wilt cap connected with rubber hoses to a standard gas-tightness device and eliminates any disadvantages. The drawing shows the proposed device which consists of a metal cap / with a rubber ring seal 2, two fittings m gkph rubber hose; one of them is connected to the patra bco: going to the water meter of the 0.42 gas permeability gauge, and the second with the help of a brush connected by a nipple f, b mm, screwed into the nest of the same device the cap /, which is pressed with a rubber seal, onto the casing with an IOTI hand with a special clamp. By turning the instrument's crank to the “test” position while lowering the bell, the reading of the pressure gauge is recorded. Then the thickness of the shell at the gas permeability determination point is measured with a barbell and the gauge is converted to gas permeability according to the table
