1.1 Scope and denitions

1. INTRODUCTION

1.2 Description

This manual provides installation, operation and maintenance instructions for the Ingersoll Rand NX Blowers, which may be abbreviated to “blowers” in the remainder of this manual. You must use the blowers as specied in this manual.

Read this manual before you install and operate your blower. Important safety information is highlighted as WARNING and CAUTION instructions; you must obey these instructions. The use of WARNINGS and CAUTIONS is dened below.

WARNING

Warnings are given where failure to observe the instruction could result in injury or death to people.



Cautions are given where failure to observe the instruction could result in damage to the equipment, associated equipment and process.

The identication and rating plate (Figure 1, item 13) provides specic details about the blower, such as its Item Number and so on.

The following warning symbols may be tted to the blower or associated equipment:

1.2.1 Introduction

•

Refer to Figure 1.The NX blowers are positive displacement blowers, which incorporate two three-lobe rotors (8). One of the rotors is driven by the drive shaft (5).The other rotor is maintained in the correct phase relation by timing gears.The timing gears and the bearings on the rotors and drive shaft are lubricated by oil in the drive end cover (4) and non-drive end cover (12).

The blowers are supplied in ‘bareshaft’ form. You must connect your own coupling or belt drive system (see Section

3.6) to the drive shaft (5) in order to operate the blower.

The blowers are available in eight dierent positions depending:

Flow direction

•

Shaft position

•

Direction of rotation

•

Refer to Section 2.7 and gure 2 for the Item Numbers of the dierent blower versions.

1.2.2 Principle of operation

•

During operation, the inlet gas stream to be pumped/ compressed enters the blower at the inlet (2).

Warning – refer to accompanying documentation.

Warning – hot surfaces.

Ear defenders must be worn.

The units used throughout this manual conform to the SI international system of units of measurement.

Equivalent values in imperial units are also included.

As the two contra-rotating rotors turn, the inlet gas is trapped in the chambers formed between the rotors and the blower-body, and is eventually forced out of the blower at the outlet (3).

1.3 Applications

All of the NX blowers are suitable for pressure or vacuum operation.

The blowers are suitable for pumping/compressing ambient air, and non-ammable gases, gas mixtures and dusts. The blowers are not suitable for pumping/compressing ammable or pyrophoric gases, gas mixtures and dusts.

The materials of construction of the blowers are specied in Section 2.6. Before you use the blower, you must ensure that these materials are compatible with the gases and vapours which you will pump/compress or which may exist in the external atmosphere.

You must ensure that your blower is suitable for your application.

If you have any doubts as to the suitability of the blower for your application, contact your supplier or Ingersoll Rand for advice.

3. INSTALLATION

www.fraserwoods.ca



Ingersoll Rand will accept no liability or warranty claims if your installation includes any modications or additions to the blower without the prior written approval of Ingersoll Rand, or if the blower is incorrectly installed.

3.1 Installation safety

WARNING

Obey the safety instructions listed below and take note of appropriate precautions when you install the blower.

•

A suitably trained and supervised technician must install the blower.

Ensure that debris and dust does not get into the blower or

•

the system pipelines when you install the blower. Check that all of the required components and tools are

•

available and of the correct type before you start to install the blower.

Use suitable new gaskets/seals to connect the blower into

•

your system. Do not re-use old gaskets/seals. If you will t the blower into an existing system, disconnect

•

the power from the drive system before you start installation, so that the drive system cannot be operated accidentally.

3.2 System design and safety

WARNING

Ensure that the maximum dierential pressure across the blower specied in section 2.2 cannot be exceeded. If it is, the drive will trip and the blower will stop. Obey the safety instructions listed below when you design and build your system:

3.2.1 General requirements

•

Your system must be suitably designed for correct operation of the blower. Note that:

You must design a suitable pipeline to t the blower inlet/

•

outlet connections. refer to Section 2.8 and to Figures 3 and 4 for the dimensions of the blower connections.

Your system design must ensure that, when the blower

•

is in its nal operating location, you can see the oil-level sight-glasses and can access the oil ller and drain plugs.

•

Your system must incorporate a suitable mounting platform: see Section 3.4 for more details.

The blower must be suciently level for correct operation:

•

see Section 3.4 for more details. There must be at least 150 mm (6 inches) of free space

•

around the blower, for adequate cooling-air circulation.

The gases which enter the blower must not contain solid

•

particulates larger than 25 m (9.84 x 10-5 inch) in size and must not contain more than 200 mg/m3 (1.37 x 10 of dust. Incorporate suitable lters to prevent the ingress of solids into the blower.

The temperature of the gases which enter the blower must

•

not exceed the temperature rating of the blower.

3.2.2 System safety

•

Your system design must ensure that the blower cannot

•

be operated with the inlet or discharge (outlet) pipelines obstructed.

•

Ensure that the blower cannot operate with the incorrect direction of rotation (see Section 3.7).

We also recommend that your system incorporates an

•

emergency stop facility which, once activated, must be manually reset before the blower can be operated again.

•

Your system must incorporate non-return valves (check valves), to prevent reverse rotation of the blower when it is switched o.

•

Your system must incorporate a pressure relief valve in the outlet pipeline (for pressure operation) and/or incorporate a vacuum relief valve in the inlet pipeline (for vacuum operation), to ensure that the design capability of the blower cannot be exceeded during operation. The relief valve(s) must be suitably rated/sized for the performance of the blower.

•

We recommend that you incorporate silencers, to attenuate the pulsations in the inlet/outlet gas streams.

If required, install your own acoustic enclosure around

•

the blower or ensure that people wear suitable protective equipment (such as ear defenders) when they are close to the operating blower (See section 2.4). If you install an acoustic enclosure, ensure that there is sucient space for cooling-air ow around the blower. See above

Your design must ensure that people are protected from

•

accidental contact with the blower or the outlet pipelines. During blower operation, the temperature of the blower and the outlet pipelines will be above 70 °C (158 °F). If necessary, t suitable guards.

Your design must ensure that materials or substances

•

which are ammable at temperatures of 70 °C (158 °F) or above are not close to, or in contact with, the hot blower or outlet pipelines.

If you pump/compress ammable or toxic gases, you must

•

take suitable precautions to prevent the discharge of the gases to the surrounding atmosphere.

Note: Filters, pressure/vacuum relief valves, non-return (check) valves, acoustic enclosures and silencers are available from Ingersoll Rand: contact your supplier or Ingersoll Rand for advice.

3. INSTALLATION

3.3 Unpack and inspect

WARNING

Use suitable lifting equipment to move the blower. If you do not, you can injure yourself or damage the blower. Refer to Section 2.2 for the mass of the blower.

Note that the blowers are supplied with either lifting bolts tted (as shown in Figure 1) or with lifting lugs tted. Where necessary in Sections 3.4.2 or 3.4.3, attach your lifting equipment to these lifting bolts/lugs.

3.4.2 Prepare, locate and connect blowers

• installed directly in your system

1. Use a suitable fork-lift truck or pallet truck to move the blower, on its pallet, close to where you will install it.

2. Remove all packing materials and protective covers and check the blower. If the blower is damaged, notify your supplier and the carrier in writing within two days; state the Item Number of the blower together with your order number and your supplier’s invoice number. Retain all packing materials for inspection. Do not use the blower if it is damaged.

3. Check that you have received the items. If any item is missing, notify your supplier in writing within two days

4. Look at the blower rating and identication plate (Figure 1, item 13) and check that the blower is suitable for use in your system. If the blower is not suitable for use in your system, do not continue to install the blower: contact your Supplier or Ingersoll Rand.

If the blower is not to be used immediately, replace the protective covers. Store the blower in suitable conditions, as described in Section 6.1.

3.4 Prepare, locate and connect the blower

3.4.1 Introduction

•

Take note of the following when you locate the blower and connect it into your system:

For optimum performance, ensure that the system

•

pipelines connected to the blower are as short as possible. Support your system pipelines and other components, to

•

prevent loading of the inlet and outlet ports on the blower. Incorporate exible components in your system, to

•

minimise noise and vibration. Where necessary, use gaskets/seals which are compatible

•

with the gases which will be pumped/compressed, and with the operating conditions.

The leak tightness of your system connections must be in

•

accordance with the requirements of your applications.

Note that blowers can be:

Installed directly in your system. You must ensure that your

•

system pipelines can support the blower. Prepare, locate and connect blower as described in Section 3.4.2.
