Abstract

Abstract Translated from Japanese (57)【要約】 【目的】 往復動ポンプによるポンプ移送液の脈動現象 を抑制するに当り、液圧の変動が所定範囲を越えた場合 に、これに応じて気体封入圧を自動調整でき、人的労力 の省力化に貢献し得るとともに迅速かつ正確な調整を可 能とした脈動減少装置を提供すること。 【構成】 液室15内の減圧変動により、隔膜14が基 準位置Sより液室を拡大する方向に移動した場合、設定 したストロークAを越えるようになると、該隔膜14に より弁押し棒28を介して弁25が開成し、気室16内 に気体圧が更に付与され封入圧が上昇するように自動調 整される。隔膜14が基準位置Sより液室を縮小する方 向に移動した場合、設定したストロークBを越えるよう になると、スライダー33が弁34を開成位置に移動さ せ、気室16内の気体圧を放出し封入圧を低下させるよ うに自動調整される。 (57) [Abstract] [Purpose] When suppressing the pulsation phenomenon of the pump transfer liquid by the reciprocating pump, when the fluctuation of the liquid pressure exceeds a predetermined range, the gas filling pressure can be automatically adjusted according to this. To provide a pulsation reducing device capable of contributing to labor saving of human labor and enabling quick and accurate adjustment. [Structure] When the diaphragm 14 moves from the reference position S in a direction to expand the liquid chamber due to fluctuations in the pressure inside the liquid chamber 15, when the stroke A exceeds a set stroke, the diaphragm 14 causes the valve push rod 28 to intervene. The valve 25 is opened and the gas pressure is further applied to the air chamber 16 so that the enclosed pressure is automatically adjusted. When the diaphragm 14 moves from the reference position S in the direction of contracting the liquid chamber and when the stroke B exceeds the set stroke B, the slider 33 moves the valve 34 to the open position to release the gas pressure in the air chamber 16. It is automatically adjusted to reduce the filling pressure.
