摘要： An air driven double diaphragm pump including two opposed pump chambers with an air motor having air chambers therebetween. The pump chambers and air chambers form pumping cavities divided by diaphragms. Each pump chamber includes an inlet ball valve and outlet ball valve. An inlet manifold is positioned below the pump chambers and an outlet manifold above. Tie-rods extend both across the pump from one pump chamber to the other with nuts to place the assembly in compression. Tie-rods also extend from the outlet manifold through the pump chambers, to the inlet manifold and to feet mounted therebelow. Two plates, one to either side of the air motor extend to grooves in the inlet and outlet manifold and also extend to grooves in the pump chambers so as to close of the side of the pump structure. With the plates, an outlet manifold is provided from which air may be exhausted remotely. The ball valves include small diametrical clearance and a limitation on lift for added performance. The ball valves also include seats which are sealed with the components of the pump through the use of O-rings and surfaces polished to 10R.sub.A. Belleville washers relieve thermal stresses on the tie-rods. Integrally molded diaphragms include an annular sheet about a hub. A semi-circular corrugation about the periphery provides for attachment to the pump while a cylindrical flange mates with a boss on the respective pump chamber. A stud is molded as an insert into the diaphragm. The pullout failure rate of the stud is empirically established by appropriate sizes of circumferential ribs and hub thickness to be higher than the rupture rate for the annular sheet.

摘要： An air operated double diaphragm includes an air valve, air chambers, a center section between the air chambers, pump chambers and diaphragms between the air and pump chambers harnessed together with a piston rod. The air valve includes a statically dissipative body having a bore therein with a statically insulative liner in the bore. The statically insulative liner is fully enclosed within the statically dissipative body. A valve element is slidably positioned in the liner. The liner includes annular tenons to mate with annular mortises in the statically dissipative body and an end cap is used to close the valve cylinder.

摘要： An air driven diaphragm pump includes an performance control actuator having a housing with opposed air chambers. The pump includes pump chambers facing the air chambers and pump diaphragms extending between each air chamber and each pump chamber, respectively. The actuator further includes an air valve, an intake to the air valve and an engagement. The intake includes an intake passage and a performance control intake adjuster rotatably mounted. The intake adjuster has a helical channel and a closure element extending adjustably into the intake passage. The engagement engages the helical channel for control of the intake. The helical channel has varied pitch to provide a nonlinear relationship between rotation and axial advancement of the intake adjuster. The nonlinear relationship gives flow rate proportional to the angular rotation of the intake adjuster. The end points of the channel provide a practical minimum pump performance of about 40% of maximum pump flow rate and a maximum pump performance of about 97% of maximum pump flow rate.
