Description
Известны устройства дл . испытани на .прочность стенок колодцев в корпусах шестеренчатых насосов при помощи гидравлического давлени .Known devices for. testing the strength of the walls of wells in gear pump housings using hydraulic pressure.
Однако при использовании таких устройств возникают деформации корпусов.However, when using such devices, there are deformations of buildings.
В описываемом устройстве дл устранени вредной деформации корпусов испытуемых насосов за счет раздельной подачи гидравлического давлени в зоны всасывани и нагнетани , применены вставл емые в колодцы насосов металлические вкладыши с упругой резиновой или иной оболочкой. Вкладыши прижимаютс к внутренней поверхности стенок колодцев и раздел ют зоны низкого и высокого давлений при подаче во вкладыши сжатого воздуха под давлением выше гидравлического , поступаюшего к упругой оболочке через штуцеры во вкладышах и каналы в них.In the described device, to eliminate the harmful deformation of the housings of the tested pumps, due to separate supply of hydraulic pressure to the suction and discharge zones, metal inserts inserted into the wells with elastic rubber or other sheath are used. The liners are pressed against the inner surface of the walls of the wells and separate the low and high pressure zones when compressed air is fed into the liners under pressure above the hydraulic supply to the elastic sheath through fittings in the liners and channels in them.

Устройство дл испытани на прочность стенок колодцев в корпусах шестеренчатых насосов включает в себ металлические вкладыши / и упругие фигурные резиновые оболочки 2. Вкладыши / с одетыми на них оболочками 2 вставл ютс попарно в колодцы 5 и 4 корпуса 5 испытуемого насоса, после чего через штуцеры 6 во внутренние полости 7 вкладышей 1 подаетс воздух под давлением, превышающим высокое гидравлическое давление, которым испытываетс прочность стенок 8 зоны 9 нагнетани . Проход по каналам 10, сжатый воздух прин имает по ски // и 12 оболочек 2 к стенкам 8 зоны 9 нагнетани и к стенкам /5 зоны 14 всасывани , создава верхнее и нижнее кольцевые уплотнени .A device for testing the strength of the walls of wells in gear pump housings includes metal inserts / and elastic shaped rubber shells 2. Liners / with shells 2 dressed on them are inserted in pairs into wells 5 and 4 of the body 5 of the test pump, then through fittings 6 Into the inner cavities 7 of the liners 1, air is supplied at a pressure exceeding the high hydraulic pressure, with which the strengths of the walls 8 of the injection zone 9 are tested. Passing through the channels 10, compressed air pulls the // and 12 shells 2 to the walls 8 of the injection zone 9 and the walls / 5 of the suction zone 14, creating upper and lower annular seals.
