The reason overheated boiler feed pump pump pump pump overheated common is due to bearing damage caused by friction caused by or due to lack of oil lubrication system, oil is not good cause. Therefore, after the discovery of the pump to overheat the pump lubrication system should first check whether the lack of oil or oil-containing impurities, followed by the investigation of the bearing is damaged. For just after the overhaul of the pump to overheat or rolling bearing bracket should also check whether the gap is too small cap. After the examination the pump should be checked for fever still bent shaft or two shaft misalignment while checking impeller balance adjustment shaft or two shaft concentricity adjustment, remove the impeller balance hole DG46-50 × 4 imported boiler feed water, in order to This warranty rotating balance shaft and impeller, troubleshooting. Mainly due to inadequate flow of boiler feed pump boiler feed pump flow pumps are mainly leaf damage caused by pipeline blockage or leak. For the use of belt driven pump to also consider whether caused due to belt slippage caused by inadequate low speed traffic. After investigation belt pipeline inspection, leak at the traffic jam should consider whether there is still insufficient impeller damage. Check the wheel bearings and other parts are lubricated DG46-30 × 9 boiler feed pumps, bearings lubricated avoid damage caused by poor or inadequate speed pump failure caused by inadequate flow may occur and solution Symptom Possible Cause Solution 1, the pump is not absorbent; and Pressure gauge pointer jumping injection pump enough water; water pump or pump water inside the meter leak Beyond; tighten or blockage leak out two, does not absorb water pumps, vacuum table shows the height of the vacuum inlet pipe is not open or blockage; absorbing too much resistance; suction height exceeds the allowable value is too large to check the water pipes; clean or replace the suction pipe; reduce suction height 3, see the pressure gauge at the pump outlet pressure, but still the water pump outlet resistance too; rotating in the wrong direction; impeller blockage; pump speed is not enough to check or shorten outlet; change the direction; cleaning impeller; increase the speed of the pump shaft 4, lower than expected flow pump blockage; seal ring wear too much; speed is not enough clean water pump and piping; replace the sealing ring; 5, the power consumed by the pump to increase the speed of the pump shaft is too large gland tight; impeller wear; increased pump water to loosen the packing gland or remove the play side; replacing the impeller; regulating valve reduce traffic 6, pumps appear abnormal sound in the work process, until no water flow decreased; balancing device gate early wear too wide; suction pipe too much resistance; in absorption at the air infiltration; suction height is too large; the transmission fluid high temperature regulating valve to reduce the flow; check suction piping; check valve at the end; reduce the suction height; tighten leaks or blockage; reduce the liquid temperature 7, the pump and motor shaft axis vibration is not the same one on the center line of the pump and motor 8 shaft centerline alignment bearing overheating no oil or oil is dirty; pump shaft and motor shaft is not a grease or oil change center line; the axis aligned with the centerline of the multi-stage pump (Figure), DG46-50 × 4 imported boiler feedwater boiler feed pump is provided by Anguo Pump Co., Ltd.
