Emerson VSSG, VSG Pressure Testing, Initial Oil Charging Using Non -Vilter Oils, Installation

Section 3 • Installation

Pressure Testing NOTICE

CAUTION

Do not hydro test compressur unit. Failure to comply

may result in damage to equipment.

CAUTION

The compressor unit along with other system units contain many components with various pressure ratings. Pressure relief protection provided considers the design pressure of a system components. Before replacing a pressure relief valve with a relief valve having a higher presure setting, all system

components must be evaluated for acceptability.

Pressure test in compliance with Chapter VI of the ASME B31.3 Process Piping Code.

Initial Oil Charging

Using Non -Vilter Oils

CAUTION

Do not mix oils. Failure to comply may result in

damage to equipment.

NOTICE

Vilter does not approve non-Vilter oils for use with Vilter compressors. Use of oils not specified or supplied by Vilter will void the compressor warranty.

Due to the need for adequate lubrication, Vilter recom- mends only the use of Vilter lubricants, designed spe- cifically for Vilter compressors. With extensive research that has been performed, we are able to offer gas com- pression lubricating oils. Use of oil not specified or sup- plied by Vilter will void the compressor warranty.

Please contact your local Vilter representative or the Home Office for further information.

Unit Oil Charging and Priming

WARNING

Avoid skin contact with oil. Wear rubber gloves and a face shield when working with oil. Failure to comply may result in serious injury or death.

Failure to follow these instructions will result in bearing damage and compressor seizing and will void any and all warranties that may apply.

Typically, the compressor unit is shipped from Vilter with no oil charge. The normal operating level is between the two sight glasses on the oil separator, see Figure 3-15. Refer to supplied GA drawing for unit specific oil charge requirement.

For regular oil charging and draining procedures, see Section 5.

Tool Required:

•Oil Pump, Maximum 2-3 GPM with Motor approved for Division 1 or Division 2 and with ability to over- come suction pressure.

(Reference Figure 3-17)

1.At initial start up, compressor unit must be off and depressurized prior to initial oil charging.

2.Using a properly selected oil pump, connect oil pump to oil separator drain valve (4). For oil separa- tor drain valve location, see Figure 3-16.

3.Open oil separator drain valve (4) and fill oil separa- tor (3) to Maximum NON-Operating Level.

4.Once Maximum NON-Operating Level has been reached, shut off oil pump, close oil separator drain valve (4) and remove oil pump.

5.If equipped with remote oil cooler, refer to Priming Remote Oil Cooler and Piping procedure.

PRIMING OIL COOLER (SHELL AND TUBE) AND PIPING

If equipped with a shell and tube oil cooler, continue with the following steps:

6.Close shut-off valve (8) at oil filter inlet. Do the same for second oil filter, if equipped with dual oil filters. For shut-off valve location, see Figure 3-16.

7.Open oil bypass shut-off valve (5). For oil cooler by- pass valve location, see Figure 3-16.

8.Energize compressor unit.

9.Close oil mixing valve (oil temp. control valve) (7) via control panel. In Manual Mode, change “Manually Open (%)” value to “0”.

NOTE

The oil cooler is considered primed when the oil

level in the separator is constant.

10.Run the oil pump (6) twice for 1-2 minutes. Repeat this step until the oil level (9) is constant.
