1.The steel ball passes through two parallel bars of spaced 9.5mm, Or 10pcs used balls as a group, and balance the mass,the mass must more than 34g.
They are mounted on two horizontal axes.Each cylinder can be tested one test.
There should be no bulge in the cylinder caused by welding or fixing Close the cylinder with an 8 mm thick flat cover.The cylinder is closed by 8mm thick flat cover.Secure seal through seams on flat cover The abrasive consists of stainless steel round balls with a diameter of 10 ± 0.5mm Make the steel ball pass through two parallel bars with a spacing of 9.5mm, or weigh the mass of 10 used balls as a group, and the mass can not be less than 34g, so as to quickly check the diameter of the ball.
An electric motor (about 1kW) must ensure that the cylinder rotates at a uniform speed of 100tr / min ± 5 TR / min. One can automatically interrupt the engine operation at the end of the test.
