Significant fluctuations in the outlet pressure and flow rate of the high-pressure coal slurry pump
Thread Content
The high-pressure coal slurry pump underwent normal barring and exhaust, and started up properly; then why are there still significant fluctuations in the pump’s outlet pressure and flow rate? I would be grateful if experts could share their insights. Thank you! This post was last edited by Tianya Langji on 2009-2-13 08:49.]
In my opinion, the possible reasons are as follows: First, your exhaust is not complete; there is still gas at the water-coal slurry end or at the drive fluid end； Second: If there is a cylinder but no measurement is taken, it might be due to a ruptured diaphragm or other reasons ； Third: The nitrogen pressure in the outlet buffer tank of the high-pressure coal slurry pump is insufficient ； This post was last edited by shanxg on 2009-4-9 21:19]
Thank you. It is through communication that improvement comes, and it is through interaction that we gain something!
As a supplementary point, for German Fillau pumps, it could also be a cracked rubber hose.
Additional note: 1. Check the gauge to see if it’s a problem with the gauge! 2. Check the inlet valve to ensure it is fully open! 3. Check whether the pressure of the gasification furnace is stable! 4. Is the slag port pressure difference stable?
Tell me which coal slurry pump you have chosen? Which company are you from? I have already solved this problem
Coal slurry pumps that are not of the Ruwa type generally do not experience major problems. The phenomena mentioned by the poster are either due to 1) one of the cylinders not functioning properly, or 2) insufficient pressure in the pump’s outlet buffer tank. (This possibility is generally high). 3. Another issue is insufficient suction volume of the coal slurry.
Consider the issue of inlet and outlet check valves and conduct an inspection.
