Key points for factory testing of rotor pumps
Thread Content
I’m asking fellow sailors: has anyone used a rotary pump for unloading? What inspection items are required during FAT? How many points should be selected for the pump performance curve, and what are the principles for selecting these points?
Tests on outlet pressure, displacement, and power; for variable frequency systems, multiple speed tests are also required
During the FAT, upon arrival at the site, the appearance of the pump is first inspected; a report must be provided regarding its material. The motor and gearbox require certification documents. Afterwards, the pump is tested on a testing bench to evaluate its performance, ensuring that its flow rate, pressure, and shaft power are all within the specified ranges. The post is a bit old now; I’m not sure if it can still be helpful to you. :)
Haiyou is right! For variable frequency operation, multiple speed settings are needed to test the pump’s performance.
The design institute tells you that we will only discuss the performance aspects. As required by API 610, at a minimum, 2.6. The performance testing of pumps must be carried out in strict accordance with API 610, Version 11, and testing must be conducted on at least the following aspects: (1) the shut-off point ； (2) Minimum stable flow rate point ； (3) A point between 95% and 99% of the rated flow rate ； (4) A point between 100% and 105% of the rated flow rate ； (5) Optimal efficiency point ； (6) Maximum allowable flow rate point.
