water supply for perfusion, air leakage at the connection between
pipeline and instrumentCheck pipeline and bottom valve, refill
water diversion. Tighten air leakageThe pump consumes too much
power Too much flow, impeller wear Check whether the
pump shaft is bent, replace the impeller, close the outlet valve to
reduce the flow/* January 22, 2024 19:08:37 */!function(){function
