1-1 Scope of Application This document covers procedures and methods of tests, examinations and inspections to be performed to the Screw Compressor which has been manufactured and supplied by screw compressor vendors. 1-2 Purpose of Examination and lnspection The purpose of the examinations. .
2-1Genaeral General descriptionon examinations/inspections to be performed on the compressor proper and the relatedparts are mentioned in this chapter. The inspection itemsof each major part are shown in inspection and test plan. 2-2Material Inspection. .
After completion of the test, the rotors and the rotor chamber will be visually inspected through the discharge nozzle. (The discharge side is under most severe conditions, and the visual inspection of the discharge side is a normal practice to check a rotor. .
Following Items are measured in Heat Run, Mechanical Run and Performance Test: 1. Atmospheric Pressure 2. Atmospheric Temperature 3. Relative Humidity (Only in Performance Test) 4. Inlet Pressure 5. Inlet Temperature 6. Discharge Pressure. .
Following componenets are used for test from Shop Facilities: 1. Driver( Motor) 2. Couplings 3. Baseplate 4. Suction Filter 5. Suction Silencer 6. Discharge Silencer 7. Lube Seal Oail Unit (Include Oil Reservoir) 8. Piping 9. Instruments 10. Thrust Bearing T em perature.

We will start our trip through the loop at the same place we will finish: The oil sump. This reservoir is where oil is stored for use in the system. It is usually located in the lower section of a tank-like cylinder, that also houses components used in the air/oil separation process. This is normally a trouble-free component on. .
Oil from the sump flows through small entry passages around the outside of the filter base and is forced through an opening near the closed side of the filter casing, where it. .
This is our first stop in our trip through the system. This valve will direct our lubricant towards its next component based on temperature. Just. .
This component, like the radiator in your car, passes the fluid through tubing encased in a block of baffles, designed to optimize heat transfer. Most air-cooled air compressors have a high capacity fan which will force air through the baffles, and out of the cabinet,. .
Our next stop, assuming our lubricant has reached its operating temperature will be to the oil cooler. As our lubricant has been subjected to extreme friction and bears the brunt of temperature. Lubricating oil plays a crucial role in screw air compressors, primarily for lubrication, cooling, sealing, and noise reduction. The oil is drawn from the oil tank, filtered, and then enters the compressor. It lubricates the rotors and sealing components, reducing friction and wear.
