Description
Przedmiotem wynalazku jest sposób badania tworzyw konstrukcyjnych na jednoczesne dzialanie erozji i kawitacji.The subject of the invention is a method of testing engineering materials for simultaneous erosion and cavitation.
W znanych dotychczas sposobach badania tworzyw konstrukcyjnych na jednoczesne dzialanie erozji i kawitacji erozja deformuje powierzchnie elementów urzadzenia badawczego lub próbki tworzywa zmieniajac natezenie dzialania kawitacji i erozji, a tym samym powodujac dodatkowe bledy pomiaru.In the previously known methods of testing engineering plastics for simultaneous erosion and cavitation, erosion deforms the surfaces of the test device components or the material samples by changing them the intensity of the effects of cavitation and erosion, thus causing additional measurement errors.
W znanym sposobie badania odpornosci tworzyw konstrukcyjnych na dzialanie erozji piaskowej badana próbka tworzywa umieszczona zostaje na wewnetrznej powierzchni oslony cylindrycznej. W oslonie cylindrycznej wiruje tarcza wyposazona w lopatki. Tarcza odrzuca ku obwodowi zewnetrznemu mieszanine cieczy i cial stalych. Utworzony w ten sposób wirujacy wewnatrz oslony cylindrycznej pierscien mieszaniny oplywa próbke tworzywa powodujac zuzycie próbki.The known method of testing the resistance of engineering plastics to sand erosion was tested a plastic sample is placed on the inner surface of the cylindrical sheath. In the cover a rotating disc equipped with paddles is rotating. The shield throws the mixture towards the outer circumference liquids and solids. The mixture thus formed rotating inside the cylindrical shell flows around the sample of the material causing wear of the sample.
Sposób badania tworzyw konstrukcyjnych na jednoczesne dzialanie erozji i kawitacji polega rm tym, ze próbke tworzywa umieszcza sie na koncówce urzadzenia powodujacego drgania próbki z czestotliwoscia dostateczna do wywolania efektu kawitacji na jej powierzchni, wprowadza do oslony cylindrycznej w której poddaje sie próbke zuzyciu erozyjnemu, a nastepnie jednoczesnie wlacza urzadzenia powodujace zuzycie kawitacyjne i erozyjne i w znany sposób wyznacza zuzycie tworzywa.The method of testing engineering plastics for the simultaneous action of erosion and cavitation is based on the fact that the material sample is placed at the end of the device causing the sample to vibrate with frequency sufficient to create a cavitation effect on its surface, it introduces into a cylindrical shield in which subject the sample to erosive wear and then simultaneously turn on the devices causing the wear cavitation and erosion and determines the wear of the material in a known way.
Sposób wedlug wynalazku umozliwia ustalenie stalego natezenia zuzycia erozyjnego i kawitacyjnego w czasie badania.The method according to the invention makes it possible to establish a constant intensity of erosive and cavitation wear during the test.
Na rysunku przedstawiono urzadzenie reajizujace sposób badania tworzyw konstrukcyjnych wedlug wynalazku. Próbka tworzywa 6 zamocowana jest na koncówce 5 urzadzenia wytwarzajacego drgania próbki.The figure shows a device implementing the method of testing construction materials according to invention. The material sample 6 is attached to the tip 5 of the sample vibration generating device.
Calosc umieszczona jest poprzez uszczelnienie 4 w oslonie cylindrycznej 1, w której wirujaca tarcza 2 z lopatkami 3 wytwarza wirujacy pierscien unoszonej cieczy i cial stalych.2 94167The whole is placed through the seal 4 in the cylindrical casing 1, in which the rotating disc 2 with 3 paddles produces a rotating ring of liquid and solids to be raised. 2 94167
