Companies that operate high capacity production plants such as those in the chemical process and power industries require cooling towers with large amounts of heat-rejection capacity.
The Cooling Tower Gear Box is one of the key components of the equipment in medium and large cooling towers. It is the most expensive component in many cases, and the one exposed to the hardest working conditions. Therefore, it is important to carry out appropriate maintenance work following the manufacturer’s instructions.
Correct lubrication prevents metal-to-metal contact between teeth and bearings, reducing friction losses and dissipating the heat generated, as well as preventing corrosion.
Greasing is done by bubbling as standard. Gears and bearings are greased by immersion in the oil bath. Although normally the upper bearings and labyrinth seal are greased, in some cases their lubrication is also ensured by oil circulation through an integral pump driven by one of the gearbox shafts.
It is important to check the oil level weekly using the dipstick with the gear unit stopped. The first oil change should be made after 100 hours, never after 800 hours of operation. Subsequently, the oil should be renewed after 4000 to 8000 hours, never after 18 months of operation. The oil must be drained while the gearbox is still hot, by removing the filler plug. Oil samples can also be taken periodically for subsequent analysis, thus checking the condition of the oil, deterioration, wear particles, possible water contamination, etc. In this case, it is advisable to install a valve for sampling. This prior analysis will facilitate maintenance tasks, which may shorten or lengthen the intervention times, and will help us to get a better control of the gearbox, anticipating possible breakdowns, improving its performance and increasing its operating life. Only the type of oil and viscosity index indicated on the gearbox plate should be used.
On the other hand, the grease must contain EP additives and NLGI-Grade 3 consistency. It is important to add grease every 800 hours of operation at all greasing points.
The dipstick plug normally has an air hole to prevent any overpressure. The ventilation hole must be checked regularly to ensure that it is not blocked.
If the unit does not work continuously, it is recommended that a backstop be installed to prevent the fan from rotating in the opposite direction due to eddy currents. The backstop is integrated in the gear unit and is lubricated with the same oil bath as the gear unit. It does not require any additional maintenance except for inspection every two years.
We provide different sizes of Cooling Tower Gear Box for cooling tower application .These are two stage gear boxes having 1st stage out of spiral bevel pair duly case hardened and lapped with another helical pair with case hardened and ground. Normally output shaft is vertically upward which takes the dynamic thrust of fan as well as dead weight of the same by virtue of thrust bearing which is provided in the Cooling Tower Gear Box.
Our GearBoxes are heavy duty, right-angled, spiral bevel and spiral bevel cum helical type designs. They are specially designed for rugged cooling tower conditions.
We provide Right angle Gear Box in single/double reduction is intended to satisfy characteristic requirements and conditions encountered in cooling tower applications. These are designed as direct replacements for the equivalent models & ratios in terms of critical mounting dimensions. Our engineers will be pleased to assist in case of unusual conditions attracting special requirements. They are specially designed for rugged cooling tower conditions. The rating practice and operation considerations are governed by CTI STD-111 (86).
