Step 1
For this process to work efficiently and without causing damage to the pump, the liquid needs to be clean. This is because the pump operates with close tolerances, meaning the components of the pump are very close together. If the liquid is not clean, particles Show more…

Which of the following can be the cause/causes of an air-cooled compressor getting overheated during operation? 1. Insufficient lubricating oil. 2. Broken valve strip. 3. Clogged intake filter. Select the correct answer using the code given below: (a) Only 3 (b) Only 1 and 2 (c) Only 2 and 3 (d) 1,2 and 3
Consider the following statements: In a reciprocating compressor, clearance volume is provided 1. so that piston does not hit and damage the valves 2. to account for differential thermal expansion of piston and cylinder 3. to account for machining tolerances 4. to achieve isentropic compression Which of these statements are correct? (a) 1,2 and 3 (b) 1,2 and 4 (c) 1,3 and 4 (d) 2,3 and 4
