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.

Plug your tool into your compressor’s airline hose and turn on the compressor. Turn the regulator counterclockwise to release pressure and clockwise to increase it. To change a switch, take the cover off the pressure switch and look for the cut-in and cut-out adjustment screws..

US Air variable speed compressors are capable of running at pressures ranging from 100 PSI to 175 PSI without requiring any mechanical modifications. Adjusting the pressure is simple and can be done either via the compressor’s control panel or through the dedicated mobile app..
Typically, you will find two settings: cut-in pressure, where the compressor starts, and cut-out pressure, where it stops. Adjusting these settings involves turning specific screws on the pressure switch. Understanding the basics of this process can help you maintain your equipment effectively..
In summary, to properly control a set of screw air compressors with a VFD trim air compressor: Ensure all air compressors have common sensing location. Set up air compressors to accept remote commands. Select proper control algorithm. The “target” algorithm is best. Test, tune and measure.

Either an electrical problem, or the compressor has tripped on a safety device. Check supply power. Check for errors on display. Check emergency stop is out. Check and reset the overload relay. If it’s a new installation, check the phase sequence. Ambient temperature too high or not enough ventilation..
Symptoms: Decreased air pressure or the compressor running continuously. Inspect Hoses and Fittings: Check all hoses and fittings for leaks. Tighten connections or replace damaged hoses. Pressure Relief Valve: Test the pressure relief valve for proper operation. Replace it if it is leaking.
