Busch Vacuum India Interview Questions, Process, and Tips

Vacuum pumps are devices that remove gas molecules from a sealed volume to create a partial vacuum.

• Vacuum pumps are commonly used in various industries such as manufacturing, food processing, and scientific research.

• There are different types of vacuum pumps including rotary vane pumps, diaphragm pumps, and turbomolecular pumps.

• Vacuum pumps work by creating a vacuum through the use of mechanical or physical means, such ...read more

Vacuum compressors are devices used to create a vacuum by removing air or gas from a closed space.

• Vacuum compressors work by reducing the pressure inside a closed space, creating a vacuum.

• They are commonly used in industries such as manufacturing, food processing, and medical applications.

• Examples of vacuum compressors include rotary vane pumps, diaphragm pumps, and liquid ring pumps.

The prime driving part of a vacuum pump is the motor.

• The motor is responsible for providing the power to drive the vacuum pump.

• It converts electrical energy into mechanical energy to create the necessary suction.

• The motor drives the impeller or piston, which generates the vacuum pressure.

• Different types of vacuum pumps may have different types of motors, such as electric motors or internal combustion engines.

2mbar is higher than 5mbar in the case of a vacuum pump.

• In the case of a vacuum pump, the lower the pressure, the higher the vacuum level.

• Pressure is measured in units of pressure, such as millibar (mbar).

• So, 2mbar is a lower pressure than 5mbar, indicating a higher vacuum level.

Oil is used in a pump for lubrication and cooling purposes.

• Oil acts as a lubricant, reducing friction between moving parts in the pump.

• It helps to cool down the pump by dissipating heat generated during operation.

• Oil also helps to seal the pump, preventing leakage and maintaining pressure.

• Different types of oil are used depending on the pump's requirements, such as viscosity and temperature range.

• Examples of pumps that...read more
