Passivation agent pump
Thread Content
Content… The injection of the passivator is not smooth; we use a pump to draw it out slowly from the tank, and it often happens that the required amount isn’t delivered. Is it a problem with the pump or something else?
It might be that the pump inlet pipeline is blocked. .
It’s possible that the crystallization has blocked the pump inlet pipeline; we often have to deal with this issue as well.
It’s possible that the inlet pipeline is blocked! Remove the pump inlet filter and clean it to see if anything dirty is blocking it! What do you do when it becomes blocked?
There are several possibilities: 1. Pump failure. 2. Blocked inlet pipeline 3. Clogged inlet filter 4. Air blockage
Do you use a pump directly? We first use a diaphragm pump to add the passivator into a dedicated storage tank, and then use a reciprocating pump to force diesel to push the passivator into the feed line behind the mixer. Is it common for the output volume not to increase? We’ve also encountered situations where the tube wasn’t inserted properly, allowing air to be drawn in. Sometimes it is due to the lubricant for the diaphragm pump becoming degraded or insufficient
Reply to 1# ybt5166889: Is it continuous injection or intermittent injection? Is a pneumatic diaphragm pump used to draw the passivator from the passivator tank into the storage tank, and then is a plunger-type metering pump used to force the diesel in the diesel tank to displace the passivator? There is a high possibility of a pump failure.
Our pumps used to be the same way too. . It is often after the rubber hose has delaminated due to being soaked in oil. . The pipe is blocked. . Replace the pipe
When using a pneumatic diaphragm pump, low temperatures and high viscosity of the passivating agent can also cause the pump to fail to deliver fluid; you can try heating the passivating agent tank with steam
