Desulfurization pump routine maintenance and precautions
Due to the predominantly corrosive liquids delivered, desulphurization pumps require special care during installation, use, and maintenance to avoid the risk of corrosive fluid leakage and at the same time avoid equipment loss To extend the service life of equipment. For specific circumstances, the daily maintenance of desulfurization pump should do the following: 1, the maintenance of the shaft seal Packing seal pump to regular testing of seal water pressure and water, to always keep a small amount of clean water flow along the axis, and regularly adjust the filling pressure Cover, 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 efficient pump operation, it must promptly adjust the gap between the impeller and the front guard, adjust the impeller clearance preferred stop pump, loosen the bearing box compression bolts, loosen the adjustment nut, the bearing assembly to Before moving, rotate the shaft by hand in the rotation direction of the pump until the impeller rubs with the front fender, and then use the adjusting bolt to make the rotor move backward and record the clearance before and after moving evenly distributed between the front and back fenders of the impeller to reach The impeller and the front guard, the gap between the rear guard is equal and the two dustproof discs tightened, 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. Note: 1, assembly of bearing components: the two angular contact ball bearings back-to-back mounted in the bearing box, and mounted on the shaft close to the pump shaft coupling shoulder, followed by the other end of the shaft into the oil pan, cylindrical roller Bearings, both ends of the round nut fastening bearings, the shaft into the bearing body, respectively, a good bearing box and bearing gland, put dust disc, retaining ring, round nut, sleeve, and mounting bracket on. 2, packing seal assembly assembly: packing seal components, including packing boxes, bushings, packing rings, packing and packing gland and other parts. Filler selection of wear-resistant, corrosion-resistant carbon fiber filler. 3, the pump head part of the assembly: After the pump casing fastening bracket, and in the pump casing into the stuffing box, installed on the shaft key, "O" ring, equipped with impeller (or impeller ring) After the rear guard mounted pump case on the impeller fastened on the shaft, in order to put on the back guard "O" trap, volute, the former guard set "O" trap, and installed in the vortex Shell, and finally the former pump casing and pump casing together. Tighten the bolt. Note that the assembly should be placed in the sleeve, the impeller and impeller, packing box and the guard, the volute, the seal between the front shield "O" trap placed in the correct and pressed.
