As the saying goes, Gold Nine and Silver Ten, September is the peak season of production and sales, but if the melt pump on the production line suddenly breaks down, that's terrible, how can we ensure that the melt pump does not lose links at the critical moment? The following Haike melt pump with everyone pull a melt pump can not discharge the situation should be how to deal with: If the melt pump can not discharge the situation, then first to see whether the rotation direction is correct, if wrong, please adjust to the correct. Check again if the suction and discharge valves are inadvertently closed, and if so, open the valves. There is also the possibility that the melt pump inlet has no material or pressure is too low, then check the boredom and pressure gauge to make sure there is no problem to restart. If the feed viscosity is too high, the melt pump can not bite material, and there will be a possibility that the pump can not discharge.
