The electric circuits of the cooling tower motors are relatively vulnerable and are more likely to be problematic during their work. Owing to their sophisticated production, it is difficult to maintain and places higher demands on the integrity of maintenance personnel。
Maintenance of the cooling tower motor
Cleaning of rotors and rotors: many small acids are released when the circuits of the cooling tower electric power units are burned. The main attachments to these substances are the inner surfaces of the beams, rotors and machine parts, some of which are dissolved in the arcs of refrigerated oil tanks. Therefore, at the beginning of the repairs, the spare parts were completely cleaned and all refrigerated oils replaced. The manufacturer of the cooling tower motor indicated that the maintenance staff had unloaded the refrigerated oil from the warp shafts and used carbon tetrachloride or gasoline to clean the rotor cores, machine parts and warp shafts. After cleaning, apply refrigerated oil to the surface of these parts to prevent their rust, as rustproof powder can easily block dry filters and affect their useful life。
Cleaning of stationary iron cores: after removing the circuit, the manufacturer of the cooling tower power plant indicated that carbon tetrachloride or gasoline should be used to clean the stationary cores carefully. After washing, you need to wipe and dry. Otherwise, the iron will remain. Acidic refrigerated oils on iron cores can also cause some corrosion to the new wires installed on the steel core. In addition, once the coil is exposed to oily substances, the effect of impregnated insulation varnishes will be unsatisfactory, resulting in maintenance failure。
Maintenance of cooling tower filling:
Central air-conditioning cooling towers are a water treatment facility. Contaminated after long periods of use, commonly referred to as slurry, can lead to ageing and fallout of the fillings due to the accumulation of impurities, etc. Such problems appear insignificant, but affect the working efficiency and useful life of cooling towers. To this end, cooling tower fillings are regularly cleaned and maintained。
