The paper analyzes the pneumatic pump for SN-ratio test by use of the direct-product of internal and external tables , and has determined the optimal parameters.
采用内、外表直积法,对风动水泵进行了SN比试验分析,确定了其最佳参数组合。
Pump will not overheat: powered by compressed air in the exhaust is an endothermic process of expansion, pneumatic pump when the temperature is lower, non-harmful gas emissions.
