Boiler feed pump flow is mainly due to pump damage, pipeline blockage or leakage caused. For the use of belt-driven pump also consider whether due to belt slip caused by low speed caused by insufficient flow. After checking the belt to check the pipeline, the flow blockage is still inadequate leakage should consider whether the impeller damage. Check the impeller and bearings and other parts of the lubrication, to avoid poor lubrication due to poor lubrication or damage caused by insufficient flow.
The pump is not absorbent, pressure gauge and vacuum gauge pointer violently beating is due to inadequate perfusion water. Pipelines and connections leak. Check the bottom valve hand leaks, then irrigation foot water, tighten the leak.
Pump power consumption is too large mainly due to the packing pressure is too tight, and fever, impeller wear, pump flow increases. The solution to adjust the packing gland, check the pump shaft is bent, replace the impeller, increase water resistance, lower flow.
Caused by pump overheating is due to friction caused by bearing damage, or due to lack of lubrication system, poor oil quality caused. Therefore found to pump overheating after the pump should first check whether the lack of lubrication system or oil contains impurities, etc., followed by inspection bearing damage. Overheating of the pump body that has just undergone an overhaul should also check whether the clearance of the rolling bearing or bracket cover is too small. After the above inspection, the pump body still appears fever should check the pump shaft is bent or two axes are not the same, check the impeller balance, adjust the pump shaft or adjust the concentricity of the two shafts, clear the impeller balance hole, in order to ensure the pump shaft and impeller rotation Balance, troubleshoot
Pump abnormal sound, the pump is not water is mainly suction pipe resistance is too large, there is air infiltration in the water absorption, that the liquid temperature is too high. Overhaul the suction pipe, check the end of the valve, reduce the height of water absorption, blockage of gas leakage, reduce the temperature.
Bearing overheating, the reasons for the pump vibration motor and pump do not heart, bearing lack of oil or wear. High-speed motor and pump center, refuel or replace the bearings.
The establishment of pump parts failure and replacement records, a detailed grasp of the damage time of various components in order to facilitate the replacement of components in time before the end of life, to avoid damage to parts found in time after damage to the unit. In addition, but also to strengthen the pump lubrication system maintenance, regular inspection of the amount of lubricant, lubrication of parts in a timely manner to avoid "dry grinding" and so on. Lubricant before adding to pay attention to check the oil and add cleanliness of the mouth, to avoid adding impurities into the bearing damage. In the conservation should pay attention to the feed pump system piping inspection and maintenance, timely leakage of plugging, rust-proof coating on the outside of the pipeline should always be checked, the coating spalling timely spraying, in order to ensure that the tube Road corrosion resistance. Maintenance also need to pay attention to the pump water treatment system inspection and maintenance.
Pressure gauge pressure, but still not water is mainly due to the resistance of the outlet pipe is too large, the rotation direction is wrong. Impeller clogged, insufficient pump speed. Check or shorten the water pipe, check the motor. Clean impeller to increase pump speed.
