1.04.012 Dial Indicator set up on Recip Compressor coupling instructions

This Policy is under development and not completed for information regarding this policy contact Area Manager, Director of Field Service or Flogistix Engineering.

Purpose

The purpose of this procedure is to establish the minimum requirements installing Dial Indicators for measuring coupling alignment on recip compressors using shim pack style couplings between the compressor driver and the recip compressor. This applies to all Flogistix recip compressor packages equipped with Ariel compressors.

Procedure

This procedure applies to all units that are in currently in service in the field, at a repair shop, and in storage yards. Flogistix Service Technicians will perform the procedure of properly installing the dial indicators to check and adjust the coupling alignment on to prevent miss-alignement or distortion of the compressor coupling.

Before any work is performed a JSA must be completed according to Flogistix procedure along with any customer requirements before any work is started.

Before any work is performed on the compressor make sure all pressure has been relieved from compressor and process piping on skid. Proper LOTO procedure must be done on compressor unit.

Installing Dial indicators: There are two ways to install the dial indicators with a magnetic base or a built bracket that uses a bolt from the flywheel to hold a bracket and rod for mounting the dial indicators.

This procedure requires a magnetic base preferably a Starrett brand and two (2) Starrett Dial Test Indicator sets Part #196A1Z

Magnetic Base:

Using a Starrett brand magnetic base, mount the magnetic base so that the rod on the magnetic base is positioned like the photo below.

Then using the clamp and long rod from the Starrett dial indicator set.

• Mount the clamp with the rod pointing toward the compressor as in the photo below.

• Place one dial indicator closest to the engine so that the indicator pin of the indicator will be set on the outer radius of the compressor coupling hub. As shown below

• Place the next dial indicator that is furthest from the engine with the indicator pin of the indicator set on the face of the compressor hub that faces the compressor. As shown below

• Adjust the dial indicators so that when the indicator pins touch the coupling hub that the indicator needle will travel one full turn.

  • Once indicators are set make sure all clamps and rods are tight to prevent any false movement of the Dial Indicators.

Flywheel Bracket:

Using a bracket with a rod attached, mount the bracket so that the rod on the bracket is positioned like the photo below.

• Place one dial indicator closest to the engine so that the indicator pin of the indicator will be set on the outer radius of the compressor coupling hub. As shown below

• Place the next dial indicator that is furthest from the engine with the indicator pin of the indicator set on the face of the compressor hub that faces the compressor. As shown below

• Adjust the dial indicators so that when the indicator pins touch the coupling hub that the indicator needle will travel one full turn.

  • Once indicators are set make sure all clamps and rods are tight to prevent any false movement of the Dial Indicators.

Responsibilities

Management - Management is responsible for implementing, supporting, and enforcing the requirements of this procedure to their respective locations/area.

EHSS - Responsible to assist in the implementation of this procedure and to review for effectiveness.

Employees, Contractors, Vendors, ETC. - Are responsible to follow the follow the requirements outlined in this procedure and ask for assistance

Scope

This procedure applies to all recip compressor units driven with either a Gas engine or electric motor and is applicable to all Flogistix employees, contractors, and temporary employees.

Hazards

Employees should be aware that units could contain flammable and toxic gasses. Potential for the possible hazards of gas ignition or fire, hot surfaces & fluids, rotating equipment. Risk of possible concentration of H2S. Hazardous gases could be in the units pressure vessels, cooler, or associated piping and risk of inhalation of hazardous gas fumes. Environmental spill of compressor oil and possible production fluids

Safety

All Personal Protective Equipment (PPE) for normal Field Mechanical duties apply for this procedure. Four Gas Monitor, which is outlined in the Flogistix EHSS Manual, PPE Section 8, Procedure 8.3 This procedure applies to all units in service in the field, at a service shop, or in any storage yard.

Insure Flogistix personnel have proper safety certification as required by the Flogistix Customer.

Insure Flogistix personnel adhere to all Customers safety practices.

Proper use of required tools

Training

All employees shall be initially trained on the following topics:

• Employee Personal Protective Equipment (PPE)

• MSDS Online System

• Emergency and First Aid procedures

• Methods and Observations that may be used to detect the presence or release of a hazardous chemicals or gas in the work place

Tools & Equipment Required

All employees performing the replacement of either the gas engine or electric motor shall be required to have the listed tools to perform job tasks:

• All required PPE according to Flogistix Safety Policy

• Assorted end wrenches up to 3/4"

• 1/2" Torque wrench

• Starrett Magnetic base
