Diaphragm metering pump pendulum assembly failure
Thread Content
The diaphragm metering pump of the rubber device failed frequently. At worst, it was repaired three times a day. Each time, the connecting rod of the pendulum assembly broke. Such a critical component has become a wearing part, please give me some advice. Medium desalted water
This is to check the factors that produce resistance, whether it is caused by the material or the mechanical installation. For reference. Some equipment may seem to be damaged simply by replacing it during maintenance. This is not advisable. The cause of the damage should be found, mainly from the structural principles.
It may be overpressure. You can check the outlet of the pump and the safety valve on the pump body. I previously made a shorter ejector rod and it worked.
Thank you for your advice. What you mean is that holding in pressure causes the force to increase and cause breakage. There is no problem with the safety valve. We have also checked this. Will high pressure in the outlet process pipeline cause it? How much shorter did you make that short ram?
The material is copper? Can it be replaced with stainless steel?
