Double cylinder double-acting diaphragm pump
An overview of the working principle and structure
1 How it works
The working principle of the diaphragm pump is shown in Figure 3-1, the motor reducer (1) drives the spindle and eccentric wheel (2) to rotate, and through the connecting rod (3), crosshead (4), piston rod (5), the rotational motion is converted into reciprocating linear motion of the piston (9) in the cylinder (10).
When the piston (9) moves to the left, the piston (9) drives the hydraulic oil to pull the diaphragm in the right diaphragm chamber (14) to the left direction, and opens the feed valve (6) with the help of slurry feeding pressure, and the diaphragm chamber is filled after sucking in the slurry; When the piston (9) moves to the left to the limit position, the slurry suction process in the right diaphragm chamber (14) also ends. At the same time, the slurry in the left diaphragm chamber (8) is pressed out.
