INSTRUMENT AIR K2A/K2B AND SERVICE AIR January 25,1997 K3A/K3B COMPRESSOR RUN-IN OPERATING INSTRUCTIONS RECORD PROCEDURE VERIFIED CURRENT AND CHECKED FOR TEAFORARY CHANGES IF FIELD COPIES REQUIRED. U5E PBF.0026:1AW NP 12 4 AND DO E CONF 1.ETE TH!5 BLOCK BY: DATE 1.0 PURPOSE The purpose of this instruction is to:

1.1 Provide guidance for compressor run-in following ring replacement.

1.2 Provide a means for obtaining after run-in data to be placed in machinery history.

1.3 The procedure for K2A and K2B (Section 5.0) is derived from Joy technical manual, TFI 5.11.2, Control No. 01193, Section 4, Page 6.

1.4 The procedure for K3 A (Section 7.0) is derived from Joy technical manual, TFI 5.11.1, Control No. 000303, Section 4, Page 7.

1.5 The procedure for K3B (Section 7.0) is derived from Joy technical manual, TFI 5.11.1, Control No. 000406, Section 4, Page 7.

3.0 PRECAUTIONS AND LIMITATIONS 3.1 While running in a compressor, prescure is adjusted by throttling the 1%" aftercooler air side vent.

3.2 Manual operation of the Total Closure valves and installed jumpers that provide manual load and unload control defeat the agastat for compressor loading delay. Ensure the compressor is started unloaded and remains unloaded for the first seven seconds to allow speed and oil pressure to build.

3.3 It is good practice to secure a compressor when it is unloaded because of the reduced load on breaker contacts.

This allows the compressor Total Closure Butterfly valves and/or unloader valves time to reposition, interstage pressure and the motor EMF l to decay prior to restart of the motor.  !

3.5 If at any time there is evidence of ring seizure, the compressor should be run at a lower pressure and consequently a lower temperature level until free. Then proceed to a higher pressure level.

3.6 The only overpressure protection available for the compressor during operation with the compressor discharge valve shut is the compressor relief valve.

4.0 INITIAL CONDITIONS FOR INSTRUMENT AIR COMPRESSOR RUN-IN One instrument air compressor in operation supplying instrument air loads with the other I

compressor isolated following maintenance and requiring a run-in.

5.0 PROCEDURE FOR K2A AND K2B '

5.1 Check for proper oillevel.

5.2 Check shut the discharge valve for the compressor to be nm in.

(IA-1 for K2A or IA-2 for K2B).

5.3 Open the 1%" aftercooler air side vent (IA-228 for K2A or I A-231 for K2B).

NOTE: The air receiverpressure indicator on the compressor gauge board will be isolated when the total closure valve operating air supply isolation valve is shut.

5.4 Shut the total closure valve operating air supply isolation valve for the compressor to be

run-in (IA-206 for K2A or IA-215 for K2B). Uncap and open the total closure valve operating air supply line vents (IA-218 and IA-219 for K2A or IA-220 and IA-221 for K2B).

NOTE: The total closure valve may now be manually operated via wrenchflats machined on the actuator shaft extension protrudingfrom the side of the actuator.

NOTE: Normaloilpressure is30-40psig. l 5.5 Unload the compressor by manually fully closing total closure valve. Start the compressor and run unloaded for a minimum of 30 minutes.

5.7 Adjust the anercocler air side vent valve for a compressor discharge pressure of 50 psig.

Run for one hour.

NOTE: Ring seiwre tendency will be checked by noting abnormal coastdown behavior such as abnormalknocking noise, vibration, or rate ofspeed decrease. Normal coastdown time is about 5 to 6 seconds. Ring seimre may be noted by operation temperatures in excess ofnormal values.

5.8 Unload the compressor by manually fully shutting the total closure valve. Shut down the compressor by placing its control switch to off and check for signs of ring seizure tendency (see Precautions and Limitations 3.5).

5.9 If the pistons are free, restart the compressor. ARer the compressor is up to speed, load the compressor by manually fully opening the total closure valve.

5.10 Compressor run-in should continue according to the following substeps. Run-in should be done at discharge pressure plateaus of 70 psig,80 psig,90 psig and 100 psig.

5.10.1 Adjust the anercooler air side vent valve for the desired discharge pressure-plateau and run the compressor for one hour.

5.10.2 Unload the compressor by manually fully shutting the total closure valve.

Immediately shut down the compressor and check for signs of ring seizure tendency during coastdown (see Precautions and Limitations 3.5).

5.10.3 If the pistons are free, restart the compressor. ARer the compressor is up to speed, load the compressor by manually fully opening the total closure valve.

Repeat Steps 5.10.1, 5.10.2 and 5.10.3 for each of the pressure plateaus in Step 5.10.

5.11 Upon completion of the one hour run at 100 psig, unload the compressor by manually fully shutting the total closure valve. Immediately shut down the compressor and check for signs ofring seizure tendency during coastdown (see Precautions and Limitations 3.5).
