Causes of damage to the diaphragm pump outlet buffer bladder
Thread Content
Let’s discuss the reasons for the damage to the bladder in the diaphragm pump outlet buffer. . Thank you
If it’s not due to overpressure, it’s usually caused by the material, or the casing has aged after being in use for too long.
I agree with what was said on the second floor; half of the reason is overpressure. I encounter this kind of situation quite often. After reminding the operator later. The damage rate is decreasing in a straight line
Reply 3# zhouxuzhen: Could it be the cause of corrosion? ? Caused by material backflow? ?
Overpressure and aging are the main causes of rupture; another factor is the choice of material. The diaphragms are usually made of nitrile rubber, but this material can be dissolved by certain media such as benzene and tetrachloroethylene. Therefore, diaphragms should not be used for handling such media; instead, diaphragms made of materials like tetrafluoroethylene, or other materials that are not affected by these media, can be used.
Reply to 5# pydch: Our company uses Viton for the seals. Then, after a failure occurs, the inner casing is gone, leaving only the supporting plate. It must be corroded
It’s not necessarily corrosion. At one of our clients’ sites, we saw that the air bags inside became shattered after breaking; if they weren’t removed in time, the fragments would be carried away by the fluid flow. Air bag types are more efficient than diaphragm types. Once it’s determined what kind of fluid is involved, an appropriate material for the air bags can be chosen – there are many options such as Viton, NBR, Butyl, and others
