INTRODUCTION

This manual provides information for the following QR-25 Series, Model 350 (Record of Change 105) compressor versions:

P Control Version P plain head assembly & no controls

L Control Version L head assembly with 2 unloader towers & a hydraulic unloader

S Control Version S head assembly with 2 unloader towers & a pilot valve

LS Control Version LS head assembly with 2 unloader towers, a hydraulic unloader, & a pilot valve with a check valve assembly

LVD Control Version LVD head assembly with 2 unloader towers, a hydraulic unloader, & a pilot valve with a lockout & check valve

These compressors are aircooled, two stage, two cylinder, pressure lubricated compressors, with up to 200 p.s.i. continuous pressure capability (201 to 350 p.s.i. intermittant pressure capability with proper configuration; consult factory). The Model 350 has a 6" low pressure piston bore and a 3.25" high pressure piston bore and a 3.5" stroke and can be run at 400- 940 r.p.m.

Available options included in this manual:

-high pressure rated cylinder and head -spin-on oil filter -hooded air filter -hooded air filter / silencer

CHANGES

since previous printing dated February 1999:

Added maintenance parts to high pressure con-necting rod and piston group: piston assemblies, with and without side sealer piston ring sets.

Changed pipe tee on head assembly from a cast fitting to a brass fitting.

WARNING !

SUCTION VALVE

UNLOADER ASSEMBLIES

DescriptionDescriptionDescriptionDescriptionDescription The Quincy suction valve unloader assembly con-sists of unloading arrangements on the suction valves, having a plunger to contact the suction valve disc and an unloader pilot valve (part no.s 110832-***, and 111422-*** & 111423-***) to automatically regu-late the passing of receiver pressure to the unload-ing arrangement.

ApplicationApplicationApplicationApplicationApplication Suction valve unloader assemblies are recommended for use on Quincy compressors where the compres-sor is to run continuously and a constant pressure is to be maintained. The purpose is to automatically unseat the suction valve of the compressor when the air supply is greater than the demand.

OperationOperationOperationOperationOperation Unloading occurs when receiver pressure is suffi-cient to overcome pilot valve spring pressure. The check ball is then unseated, allowing receiver pres-sure to pass to the unloading arrangements. The compressor will run unloaded until the receiver pressure drops to a predetermined level. At this time, the action of the ball is reversed, shutting off receiver pressure to the unloader arrangement and venting the unloader to atmosphere. This allows the compressor to load. The drive, either electric motor or combustion engine, runs continuously and must be started and stopped manually.

Pilot valve 111423-*** can be locked out, for models equipped with dual control, to provide auto-matic start/stop operation. The knurled knob at the top of the pilot can be turned clockwise, until it stops, to lock it out. A pressure switch is required to stop the motor. Failure to use a pressure switch, with the pilot valve locked out, could result in unsafe condi-tions.

A pressure switch must be incorporated whenever pilot valve 111423-*** is employed as part of the control system.

The compressor will operate in the continous run mode if the knurled knob is turned counterclockwise until it stops.

InstallationInstallationInstallationInstallationInstallation The pilot valve is to be connected to the air receiver using a minimum of 3/8" o.d. copper tube. Compres-sors in the field, not equipped with a suction valve unloader assembly, can be converted to constant speed. Consult your local Quincy Compressor Dis-tributor for assistance with conversion procedures.

ServiceServiceServiceServiceService Periodically check the filter & screens in the inlet of the pilot valve to make sure they are free of obstruc-tions. If they become clogged, remove and clean or replace. Inspect the "o"ring located in the opposite end of the pilot valve body for wear or damage;

replace if necessary.

AdjustmentAdjustmentAdjustmentAdjustmentAdjustment The unloading pressure is adjustable and is regu-lated by turning the hex nut (marked "unload adj."

in cross sectional illustrations of pilot valves). Turn the hex nut clockwise to increase and counterclock-wise to decrease the unloading pressure.

The differential (difference between unloading and loading pressure) is set by turning the hex nut (marked "differential adj." in the cross sectional illustrations of the pilot valves). Increase the differ-ential pressure by turning the hex nut clockwise -decrease by turning counterclockwise. Tighten the locknuts after adjustment.
