Share the components and maintenance of the cooling tower reducer


The cooling tower uses the principle that water and air flow contact, then exchanges heat and cold to generate steam, and the steam volatilizes away heat to achieve the principles of evaporative heat dissipation, convective heat transfer and radiation heat transfer to dissipate the waste heat generated in the industrial or refrigeration air conditioner. Reduce the water temperature of the evaporative heat sink to ensure the normal operation of the system.


The following are the components and maintenance of the cooling tower reducer:


The main components of the cooling tower reducer are bevel gears, bevel gears, helical gears and rotary bearings. Under the long-term effect of the load, the frequent failure modes of the gear are gear face wear and pitting. After the gear wears or pitting, the motion accuracy is reduced, and the noise and vibration are increased. If the size of the pitting cooling tower is large, the etch pit often becomes a source of fatigue, which ultimately leads to fatigue and fracture of the gear teeth.


Therefore, the gear contact accuracy and pitting corrosion should be checked every year. Requirements for contact accuracy: The length of the pitting pit of the cooling tower does not exceed 1/3 of the tooth length and 1/2 of the tooth height. The normal failure mode of a rotating bearing is pitting damage on the rotating body or the inner and outer ring raceways. When pitting damage occurs, the deceleration opportunity shows strong vibration, noise and heat. Since the rotating bearing is not suitable for frequent disassembly and is limited by the structure and installation position, it is difficult to directly inspect the rotating bearing. After the machine is stopped, the bearing letter is attached to the bearing letter, and the sound of the bearing rotation is carefully listened to. The sound of the normal bearing rotation of the cooling tower should be crisp, continuous and uniform. If the sound is boring, intermittent, and the card indicates that the bearing may be defective, it is necessary to remove the further inspection to determine the replacement of the damaged gear in time after the failure to ensure the normal operation of the cooling tower reducer.
