Air supply device of the pressure vibration damping device for liquid pumping reciprocating pump

摘要

(57) Abstract Objective The vibration of emission pressure of the liquid force reciprocating pump is cushionedTo the ru pressure vibration-damping arrangement in the air supplying device which supplies the air SekiIt does. Constitution You joint to emission side of the liquid force reciprocating pump (19,109)It is done, with the increase and decrease of capacity of the air part (44) aforementioned liquid force round tripAs the vibration of emission pressure of the pump (19,109) is cushioned, aforementionedAs for air part (44), pressure of aforementioned liquid force reciprocating pump (19,107)Supplying the air depending upon the pump chamber (72) which the pinch-and-swell is done with pulsation of the sending liquidThe nul of the pressure vibration-damping arrangement (42) for the liquid force reciprocating pump which is doneIn the air supplying device, the aforementioned liquid force reciprocating pump (19,109)To the pump chamber (24,120) the pressure operation chamber (70) which is communicated and, thisFrom the pressure operation chamber (70) to be small diameter, emission side the aforementioned pressure vibration gentleThe pump chamber (72) and the aforementioned pressure which are jointed to the opposition device (42)Lap wall of operation chamber (70) and aforementioned pump chamber (72) the respective sleeveThe large diameter gasket (76) and the small diameter gasket (78) which it does in both destalsIs installed and to axial direction movement becomes unrestricted the piston (74) whichThis it touches to the end face of the aforementioned piston (74), with, in the Tip aforementionedThe adjustment screw (80) which regulates the distance tonnage of the piston (74) possessingIt becomes the te.
