Gear box failure can be caused by various reasons such as lack of lubrication, overheating, worn out gears, or improper maintenance.

• Lack of lubrication causing increased friction and wear on gears

• Overheating leading to thermal expansion and distortion of gears

• Worn out gears due to prolonged usage without replacement

• Improper maintenance such as infrequent oil changes or ignoring warning signs

The type of lubricant used depends on the specific equipment and application, such as grease for bearings or oil for gears.

• Consider the operating conditions of the equipment, such as temperature and load

• Choose the appropriate viscosity and additives for the specific application

• Regularly monitor and maintain the lubricant levels to ensure optimal performance

• Examples: grease for bearings, oil for gears, silicone lubrican

• Modular plastic conveyor belts are used for food processing and packaging.

PID stands for Proportional-Integral-Derivative, a control loop feedback mechanism used in industrial processes to maintain desired setpoints.

• PID is a control algorithm that calculates an error value as the difference between a desired setpoint and a measured process variable.

• The PID controller then adjusts the process control inputs to minimize the error and keep the process variable close to the setpoint.

• The Proporti...read more

A thermowell in a tank is a protective device used to shield temperature sensors from the harsh environment inside the tank.

• Thermowells are typically made of metal and are inserted into the tank to provide a sealed chamber for the temperature sensor.

• They help protect the sensor from corrosion, pressure, and other damaging factors inside the tank.

• Thermowells also allow for easy removal and replacement of the temperature...read more
