PCBL Chemical Limited Interview Questions, Process, and Tips

Allowable shaft run out at bearing fixing area depends on the application and type of bearing used.

• The allowable shaft run out at bearing fixing area varies depending on the application and type of bearing used.

• For example, for deep groove ball bearings, the allowable shaft run out is typically 0.05 mm to 0.1 mm.

• For cylindrical roller bearings, the allowable shaft run out is typically 0.02 mm to 0.05 mm.

• It is important...read more

The internal clearance of a bearing can vary depending on the type and size of the bearing.

• Bearing internal clearance refers to the amount of internal space between the rolling elements and the inner and outer rings of the bearing.

• It is important to have the correct internal clearance in a bearing to ensure proper functioning and prevent issues such as excessive heat or premature failure.

• The internal clearance can be s...read more

The bearing outer race to bearing housing clearance is the gap between the outer race of the bearing and the housing it sits in.

• The clearance should be within the manufacturer's recommended range

• Too much clearance can cause vibration and noise

• Too little clearance can cause overheating and premature wear

• Clearance can be measured using a feeler gauge or dial indicator

• Proper lubrication can help maintain the correct clear

To avoid bearing outer race wear inside housing, proper installation and maintenance is necessary.

• Ensure proper alignment during installation

• Use correct lubrication to reduce friction

• Regularly inspect and replace worn parts

• Measure wear with micrometer or dial indicator

• Check for signs of overheating or misalignment

API seal plans are standardized plans for sealing pumps in accordance with API standards.

• API seal plans are developed by the American Petroleum Institute (API) to ensure safe and reliable operation of pumps in the oil and gas industry.

• There are various types of API seal plans, each designed for specific applications and operating conditions.

• API seal plans typically include a combination of mechanical seals, seal flush ...read more

Pressure unit is a measurement of force per unit area.

• Pressure unit is typically measured in units such as pascals (Pa), pounds per square inch (psi), or atmospheres (atm).

• Common pressure units include kilopascals (kPa), bar, and millimeters of mercury (mmHg).

• Pressure can also be measured in non-SI units like pounds per square foot (psf) or torr.
