曾收到一些同志来信,商讨(苏)茨特林所提出以及由此而派生出的扩散泵喷咀喉部面积计算公式的使用问题。因为学习不够,工作又做的很少,仅提出一点看法,供参考。 茨特林给出的油扩散泵喷咀喉部面积S的计算式为:式中Gv-泵的抽气量 P2-该喷咀级的排气压力 P1-该喷咀级的吸气压力 Y0
A number of letters were received from comrades to discuss the use of the formula for calculating the throat area of a diffusion pump nozzle proposed by and resulting from Zürich. Because I did not learn enough, my work did very little. I only made my point of view for reference. The formula for calculating the throat area S of the oil diffusion pump nozzle given by CTILIN is: where Gv - pumping capacity of the pump P2 - exhaust pressure of the nozzle stage P1 - suction pressure of the nozzle stage Y0
