Abstract:
Falling hammer semidynamic calibrat ion device is a kind of pressure generator w hich can produce analogy semisinusoidal pressure pulse simulating pressure of gun chamber and it is used as high pressure dynamic calibrat ion for pressure sensor and plast ic measuring device. Its key technology is the sealing property of pressure g enerator. A sealing part of new type of falling hammer dynamic pressure calibrator being researched in our count ry , is analyzed; lead and measuring pressure oil( a kind of mixed oil) are used as sealing medium in crack sealing, and a special topic research and experiment is done under the high pressure from 200 MPa to 500 MPa, the result is analyzed and discussed, T he conclusion is draw n that the sealing property of lead under high pressure is better than measuring pressure oil and the type of lead ring f illing seal is bet ter than the type of measuring pressure oil seal.
