Desulfurization pump maintenance
To make the desulfurization pump safe operation, long life, we must pay attention to routine maintenance, maintenance should pay attention to the following aspects: 1, shaft seal maintenance Packing shaft seal to regular testing of seal water pressure and water, always keep a small amount of cleaning Water flow along the axis, periodically adjust the packing gland, check the packing and regular replacement of packing, shaft seal water pressure, shaft seal water should meet the above (shaft seal inspection) requirements. 2, the impeller adjustment: In order to ensure the efficient operation of desulfurization pump, impeller must be adjusted in time and the gap before the guard, the impeller clearance adjustment of the preferred stop pump, release the bearing box bearing bolts, loosen the adjustment nut, the bearing assembly Move forward, rotate the shaft by hand at the same time according to the rotating direction of the pump until the impeller rubs with the front guard, and then use the adjusting bolt to make the rotor move backward, record the clearance before and after moving, evenly distribute between the front and rear fenders, Reach the impeller and the front guard, the gap between the back guard is equal and the two dustproof discs tighten, fastened on the shaft. After adjustment, re-check the impeller rotation is normal before starting again, the bearing assembly tightening bolts are tightened, and then start the pump. 3, the bearing lubrication: assembly of the bearing assembly, if the assembly is correct, the amount of oil, maintenance timely, transport life will be longer, maintenance personnel should be regularly overhaul bearing components, bearings and lubricants to check the situation, in operation must be regularly added Or change the amount of lubricant, interval and injection volume and pump speed, bearing size, continuous working hours, the number of pump stops, the surrounding environment and operating temperature and many other factors, it is necessary to gradually accumulate experience, reasonable and timely lubrication oil. 4, spare pump shaft should be rotated 1/4 turn each week, so that the bearing evenly to withstand static load and external vibration.
