往復動型無脈動ポンプにおける微小脈動の低減 : 第1報 : 圧力による容積効率低下の要因評価 Decrease of Micro Pulsation in the Reciprocating Type Pulsation Free Pump : 1st Report : Estimation of volumetric efficiency decline Factor by Pressure
There is a pulsating flow in reciprocating pumps generally to do a sign curve movement of the form. Multiplex type pulsation-free pump needs special cam form for avoiding the pulsating flow. However, a micro pulsation occurs in the start part of section of piling the flux wave form of two reciprocating pumps. The cause of this pulsation is analyzed in the present paper. And the way of amending the cam, which is necessary for eliminating the micro pulsation, is proposed and the applied result is described.
