Adjustment of pump stroke
Thread Content
We have an ammonia injection pump of the 1-to-3 type, where one motor drives three metering pumps simultaneously. What are the requirements when adjusting the stroke of such a pump? For example, if I need to adjust the flow rate, do I have to adjust the stroke of all three pumps at the same time?
It shouldn’t be necessary to adjust them together, right? If it’s a unit with one driver and two driven units, but one is large and the other is small.
No three adjustments are needed; adjusting one unit is sufficient to meet the process requirements. But it cannot be adjusted to the maximum stroke.
One for three? Is it just a direct connection between the couplings of each pump? Therefore, the strokes of the three pumps are unrelated to each other.
