Vertical desulphurization pump maintenance

To make vertical desulphurization pump can safe operation, long service life, must pay attention to daily maintenance, maintenance should be paid attention to the following aspects: 1, the maintenance of shaft seal: packing seal pump seal water pressure and water regularly detection, to always maintain a small amount of clean water along the shaft glides on and regular packing gland, check the stuffing and regular replacement of packing, shaft seal water pressure, shaft seal water shall comply with the above ( Shaft seal check) Requirements. 2, the adjustment of the impeller: in order to guarantee the vertical desulphurization pump efficiency, we must adjust the impeller with the guard interval, adjusting impeller clearance preferred when the pump stopped, loosen bolts pressure bearing box and loosen adjusting nut and bearing components to move forward, at the same time turn the shaft by hand according to the rotation direction of pump rotation, until the impeller and guard plate of friction, reoccupy adjustment bolt to make the rotor backwards, write down the movement before and after clearance, evenly distributed between the impeller front and rear guard board, reached between impeller and guard plate, plate after before clearance equal and dispatch two dust-proof plate tightly, fastening on the shaft. Must check it before starting again after adjustment of the impeller rotation is normal, the bearing components hold-down bolts are tight, then start pump. 3, bearing lubrication: bearing components in the assembly, if the assembly is correct, oil amount, timely maintenance, transportation will be a long service life, maintenance personnel should be regularly maintenance bearing components, check the status of bearings and lubricating oil, in the operation must be add or replace lubricating oil regularly, time interval and the injection volume and the pump rotation speed, bearing specifications, work time, water pump stop opening times in a row, the surrounding environment and the operation temperature and so on many factors, so must gradually accumulate experience, reasonable and timely add lubricating oil. 4, the standby pump shaft rotation will be weekly 1/4 circle, so that the bearing evenly under static load and external vibration article from: ningbo pump manufacturer' J&T water pump 】
