Types of Gearboxes for Petrochemical Application
Centrifugal Pump Gearbox
Centrifugal pump gearboxes increase motor speed to achieve the high velocities needed for fluid movement through petrochemical processes. These units typically provide speed-increasing ratios from 1:3 to 1:5, converting standard 1,800 RPM motor speeds to pump speeds of 3,600-9,000 RPM.
Centrifugal Compressor Gearbox
Compressor gearboxes handle the extreme speeds required for gas compression in petrochemical plants. Bull gear designs accommodate multiple pinion shafts driving compressor stages at different speeds from a single motor input.
Reactor Agitator Gearbox
Reactor agitator gearboxes provide the high torque and low speed needed for mixing viscous chemicals and polymers. These vertical gearboxes deliver reduction ratios from 10:1 to 300:1 while supporting agitator weights up to 50 tons.
Extruder Gearbox
Extruder gearboxes in petrochemical plants drive the screws that process plastic pellets and rubber compounds. These robust units deliver torque outputs up to 1,200,000 Nm while maintaining precise speed control for product quality.
Cooling Tower Fan Gearbox
Cooling tower gearboxes reduce motor speed to the 100-200 RPM optimal for large fan blades. These right-angle units use spiral bevel gears for smooth operation in wet, corrosive environments above cooling water basins.
Positive Displacement Pump Gearbox
Positive displacement pumps in petrochemical service use timing gearboxes to synchronize rotor or piston movements. These precision units maintain clearances of 0.1 mm between pump elements across temperature ranges of 150°C.
Reciprocating Compressor Gearbox
Reciprocating compressor gearboxes reduce motor speeds to the 300-600 RPM required for gas compression cylinders. These heavy-duty units handle cyclic torque variations of 25% through robust gear designs and torsional dampers.
