The performance (flow rate) of the sliding vane pump decreases
Thread Content
Hello, teachers! Our facility uses slide pump to unload gasoline, and we found that after using it for some time, the unloading time increased by 20 minutes compared to when it was first used. I would like to ask whether the wear of the sliding plate is caused by long-term use, or by an excessive gap in the pump chamber How should it be handled? Thank you!
If the material being transported remains unchanged, and the diameters, lengths, and heights of the pump’s inlet and outlet pipes remain the same as before. It is recommended to replace the slides of the sliding vane pump, as gasoline lacks lubricity, so wear of the slides is normal. When contacting the original pump manufacturer, specify the medium to be transported and ask if there are slurry materials with a better cost-performance ratio. I hope this can help you.
Hello! On March 4, new sliding vanes were installed, and the unloading time was acceptable, around 50 minutes, which is similar to that of a pump of the same model that is currently in use. But after using it for two days, today (March 7), the unloading time was about 15 minutes longer than that of pumps of the same model that had not been replaced. Is it perhaps because the quality of the slider material is poor? I measured the dimensions of the old slider and the new one with a caliper, and there was a difference of 1 mm. What could be the reason? Which teacher can help analyze it? Thank you!
A sliding vane pump is not as good at draining gasoline as a self-priming pump
