The clearance for big end bearing can be measured using a micrometer or a feeler gauge.

• Use a micrometer to measure the diameter of the crankshaft journal and the inner diameter of the big end bearing. The clearance is calculated by subtracting the crankshaft journal diameter from the bearing inner diameter.

• Alternatively, a feeler gauge can be used to measure the clearance by inserting the gauge between the crankshaft journal and the bearing and checking for the appropriate ga...read more

TDC stands for Top Dead Center and BDC stands for Bottom Dead Center. They are reference points in the rotation of an engine's crankshaft.

• TDC is the point where the piston is at its highest position in the cylinder during the compression stroke.

• BDC is the point where the piston is at its lowest position in the cylinder during the exhaust stroke.

• Understanding TDC and BDC is crucial for timing engine components such as valves and ignition.

• TDC and BDC are used to determine the p...read more

The clearance of TDC and BDC for a vertical reciprocating compressor can be measured using a dial indicator.

• Use a dial indicator to measure the distance between the top dead center (TDC) and bottom dead center (BDC) positions of the piston.

• Rotate the crankshaft to bring the piston to TDC and set the dial indicator to zero.

• Rotate the crankshaft to bring the piston to BDC and note the reading on the dial indicator.

• The difference between the readings at TDC and BDC will give you...read more

Focus on proper alignment, tightness, material compatibility, and proper torque during suction and discharge valve box up.

Pressure gauges are used to measure the pressure of fluids and gases in various industries.

• Pressure gauges come in different ranges depending on the application.

• The range of a pressure gauge should be selected based on the maximum pressure expected in the system.

• The accuracy of the pressure gauge should also be considered when selecting a gauge.

• Pressure gauges should be calibrated regularly to ensure accurate readings.

• Some common pressure gauge ranges include 0-100 psi, 0-500...read more

Current CTC refers to the total salary package of an individual including all benefits and allowances.

• Current CTC includes base salary, bonuses, incentives, and other perks.

• It is important to provide an accurate figure when asked about current CTC.

• Example: Current CTC is INR 10 lakhs per annum.

There are several types of valves used in mechanical engineering for controlling the flow of fluids or gases.

• Types of valves include ball valves, gate valves, globe valves, butterfly valves, check valves, and pressure relief valves.

• Valves can be classified based on their function (e.g. isolation valves, control valves), design (e.g. rotary valves, linear valves), or material (e.g. brass valves, stainless steel valves).

• Each type of valve has specific applications and advantage...read more
