A/ d
B) operational hydraulic cylinder and cooperate the adjustment of stroke to carry out the accurate adjustment just of two ratio of components.The adjustment of every component operational hydraulic cylinder stroke is the position limit switch spacing (L that drives cylinder by adjusting
A, L
B) carry out, position limit switch is magnetic switch (28,29,30,31), is positioned to drive the cylinder block outside, its spacing can be adjusted in the air piston pump running easily.It is standby to enter slurry storing tank 19 after the slurry material that two pumps extrudes respectively mixes by atomizing mixer (18).JA, JB, JC, JD, JE are relay among synchronously reciprocal control circuit Fig. 6, JA1, JA2 are often opening to touch and accounting for of JA, and JB1 is the normally-closed contact of JB, and JC1 is the normally opened contact of JC, 28,29,30,31 is magnetic switch corresponding among Fig. 4, and 26,27 is reversing solenoid valve corresponding among Fig. 4.The work of this circuit is such: not under the circuit supply situation, the state of reversing solenoid valve 26 is that piston is promoted to switch 28 directions, and rest on the position of switch 28, push piston to switch 30 positions to solenoid valve 27 equally, then switch is closed state in 28,30 under off-position.When to the power devices air feed, switch 28,30 closures are powered to JA, the JA closure, and its contact JA1, JA2 are also closed thereupon, and then JB1, JA1 closure are powered to JD, and JA2, JC1 closure are powered to JE, and JD, JE are then closed.While JD1, JE1, JD2, JE2 is also closed thereupon, JD2, the closure of JE2 causes two solenoid valves 26, the variation of 27 power supply states, two-piston is respectively to switch 29,31 move, 28,30 recover turnoff state again, the last JA1 of JA, JA2 two contacts disconnect again, but because JD1, the self-locking action of JE1 contact in circuit, JD, JE is adhesive still, keep JD2, the attracting state of JE2,26,27 still keep "on" position, piston continues to 29,31 move, arrive at switch 29 respectively until them, 31 positions, switch 39,31 closures, cause JB respectively, the JC closure, normally-closed contact JB1 then, JC1 disconnects respectively, cause JD, the variation of JE power supply state, cause JD2, JE2 opens circuit, then solenoid valve 26,27 cut off the power supply respectively turns to, two-piston is again to switch 28,30 move, and all arrive at switch 28 until piston, 30 positions, switch 28,30 is closed simultaneously, power to JA, beginning moves in circles next time, because switch 28,30 serial fashion begins the to-and-fro motion each time of two pump pistons synchronously, and the reciprocal time of two pumps is consistent.
