Description

technical field

[0001] The invention belongs to the technical field of diaphragm pump experimental devices, and in particular relates to a diaphragm stroke experimental device and a test method. Background technique

[0002] The diaphragm chamber is the heart of the diaphragm pump. The diaphragm chamber separates the propellant oil from the slurry through the rubber diaphragm, avoiding the mixing of the propellant oil and the slurry, so that the moving parts such as the piston in the cylinder run in clean hydraulic oil, thus ensuring the piston and other components service life. Therefore, it is particularly important to detect whether the rubber diaphragm is damaged and whether the diaphragm is running in a reasonable position.

[0003] The rubber diaphragm is equipped with a guide rod with a magnetic ring, and together with the oil replenishment and discharge signal detection device installed on the oil cylinder, the diaphragm stroke detection device is formed, and the r...
