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.

Three-cylinder single-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, and the motor (1) drives the crankshaft (2), connecting rod (3) and crosshead (4) through the reducer to convert the rotary motion into linear motion and drive the piston (6) to reciprocate. When the piston (6) moves to the left, the piston (6) drives the hydraulic oil to pull the rubber diaphragm (9) in the diaphragm chamber (10) to the left direction, so that the working chamber volume of the diaphragm chamber (10) increases, and at the same time the discharge valve (11) is closed, and the slurry to be transported opens the feed valve (12) with the help of feeding pressure, enters and fills the diaphragm chamber (10). When the piston (6) moves to the right, close the feed valve (6), and the piston (6) pushes the hydraulic oil to push the rubber diaphragm (9) in the diaphragm chamber (10) to the right, and opens the discharge valve (11) with the help of pressure to transport the slurry to the pipeline.
