1.1 Scope

This manual applies to Rotary Blowers of the TL Series from size 10 to size 900, both in horizontal (H) and vertical (V) versions.

1.2 Operating principle

TL Series Blowers are positive displacement blowers comprising two conjugate shaped Tri-Loberotors which rotate inside a “figure 8” shaped body. The incoming gas is trapped in the spacethat forms between the body (figure 1a, 1b) and discharged via the outlet (figure 1c, 1d). Theoperating pressure is generated by the resistance met by the gas exiting the unit. The capacity isproportional to the speed of rotation and is almost constant when the operating pressure varies.

1.3 Construction

The TL Series Blower is engineered for the smoothest possible flow of air, resulting in lowerpulsation and noise.

The body is closed at both ends by end plates in which the housings for the seals and bearingsare located. The rotors are synchronized by a pair of timing gears having helical, hardened andground teeth. The shafts have labyrinth seals; gas leaks are collected in special air spaces in the covers and are discharged into the atmosphere. Two sumps are mounted on the covers which actas oil sumps for splash lubrication of the bearings and the synchronizing gears. The gears aresecured on the shafts through conical coupling under oil pressure.

2.1 Gas conveyed

The blower can be used to convey inert gases such as air, nitrogen or other gases which arecompatible with the lubricating oil and with the materials used in the construction of the blower.

WARNING: The blower cannot be used to convey gases which are explosive, toxic

or in any way dangerous.

NOTE: To convey special gases consult Blower Engineering.

2.2 Working conditions

2.2.1 Speed of rotation – The maximum speed of rotation is shown in Table I. The minimum speed of rotation depends on the maximum allowed differential temperature.

2.2.2 Pressure – The inlet pressure ranges from 3 psig (20.7 kPa) to 15 psig (103.4 kPa). The maximum differential pressure is shown in Table I, and depends on the size of the blower. The maximum compression ratio for all sizes of blowers is 2.

2.2.3 Temperature – The inlet temperature of the gas ranges from -13ºF (-25ºC) to 122ºF (50ºC).The maximum differential temperature allowed is shown in Table I, and depends on the size ofthe blower. The maximum temperature of the gas allowed at the discharge is 266ºF (130ºC).

2.3 Capacity adjustment

Capacity can only be adjusted in one of the two following ways:

• Varying the speed of rotation. This can be achieved via belt drives or by varying the electric motor supply voltage frequency or with a double polarity motor.

• Bleeding off of excess capacity via a regulating valve on the outlet

Do not use the safety valve for this purpose because it will suffer excessive wear.

Do not re-circulate the excess gas into the blower inlet without cooling because it could cause excessive heating.

WARNING: Do not adjust the gas capacity by using throttle valves placed on the

inlet or outlet piping.

3.1 Handling

To hoist the blower, use a cable as shown in fig. 3

WARNING:

Do not use the holes in the

flanges to lift the blower.

3.2 Storage

Keep the blower in a dry cool closed environment. Do not remove the protective coveringsplaced over the blower openings. Renew the preservation every 6 months, or more frequently if the climate is damp.

3.2.1 Bearing storage – Half fill the sumps with anti-rust oil. Manually rotate the blowershaft. Dispose of the used oil in accordance with local regulations.

3.2.2 Preservation of the compression chamber – Remove the protective coverings from the blower openings. Apply a thin film of anti-rust oil to the internal surfaces of the body to the covers and to the rotor surfaces.

WARNING: Use anti-rust and foam inhibiting oil with fire point over 392ºF

(200ºC) only.

* If replacing 3V or 5V belts with the same belt length and same number of belts in 3VX or 5VX cross section, belt tension does not need to be increased.

NOTE: New drives designed with 3VX or 5VX belts should be tensioned at the respective deflection

force value shown in above table.

Simplified V-Belt Tensioning MethodStep 1– Determine the force required

to deflect one belt 1/64" per inch (1/64th cm per centimeter) of span length.

Step 2– Measure the span length ofyour drive. Compare thisdeflection force with therange given in Table V.

If it is less than the minimum recommendedforce, the belts should bere-tensioned.

If it is more than the maximum recommendedforce, the drive is tighterthan it needs to be.

4.4 Direction of rotation – air flow direction

Fig. 6

WARNING: Do not use the blower with a direction of rotation or a flow direction which

differs from that shown in figure 6.

4.5 System pipingThe diameters of the system piping must never be smaller than the diameters of the bloweropenings. If the diameters are different, use a taper connector. The system piping should beproperly aligned and supported to prevent placing stress on the blower. Provide flexible joints.The pipes must be thoroughly cleaned before connection. The gaskets must not interfere withthe gas system.

WARNING: Remove the protective covers from the blower openings before connecting the pipes.

4.6 Check valveTo stop the counter-rotation of the blower when it stops while loaded, install a check valve onthe discharge, when acting under pressure, or on the inlet when acting under vacuum conditions.

4.7 Safety valveTo limit the maximum operating pressure of the blower use a safety valve on the discharge,when acting under pressure, or on the inlet when acting under vacuum conditions.

WARNING: Install the safety valves as close as possible to the inlet/outlet at the blower,

without placing shut-off valves in-between.

4.5.1 Inlet pipe• Connect a silencer directly to the inlet of

the blower.• Thoroughly clean.• If necessary install a dirt filter for

the first 100 working hours.• Install a pressure gauge to check the dirt filter.• Support the pipe.

4.5.2 Outlet pipe• Connect a silencer directly to the

outlet of the blower.• Support the piping at the point

nearest to the flexible coupling.• Insulate the pipes so as to avoid

4.8 Electrical connectionUse only authorized specialists to set up the electrical system, working in compliance withregulations applying to the place of installation and in accordance with the requirements of the local body supplying electrical energy. Check on the motor plate:

• Voltage • Frequency• Number of phases • Absorbed current

Connect the cables as shown in the diagram accompanying the terminal box of the motor. If thediagram has not been supplied, request it from the motor manufacturer. Use electrical cables of suitable size, depending on the nominal current of the electrical motor. Keep the electric cablesaway from heat sources and/or pointed edges. The motor must be protected by means of an automatic switch set at the value of the rated current shown on the plate. For the safety of personnel,the system must be protected by a suitable grounding device.

WARNING: Blower service must be carried out only after disconnecting the electric supply.

5.1 Preliminary controlsIf the blower has been in storage for more than 6 months, check its state of preservation.

• Check the coupling or the sheave alignment• Check the belt tension.• Check that the blower shaft rotates freely manually.• Check that the safety protection devices have been correctly installed and secured.• Fill the blower with oil as described in paragraph 6.1.1.

5.2 Start up5.2.1 First start-up

WARNING: During this operation personnel are in direct contact with the blower, and

for this reason noise protection must be worn.

Open the shut-off valve.• Check that the safety valve has been set at the operating value.• Check the rotation by ‘jogging’ the motor.

WARNING: Do not rotate the blower in the wrong direction for more than a few revolutions.

Start the blower• Increase the operating pressure gradually until the rated value is reached.• After about 10 to 20 minutes check that there are no oil leakages and strange noises or

vibrations. If such problems are found, stop the blower immediately.

5.2.2 Normal start-ups – With direct start-up the motor starts even with the maximum dis-charge counter-pressure. With star-delta start-up, on the other hand, or with the starter; thecounter-pressure must be zero.

Page 12: Blower Manual

1100

5.3 Operating checks5.3.1 Daily checks – With the blower running, check:Outlet temperatures.

• Discharge pressure (when functioning under pressure).• Suction pressure (when functioning in vacuum conditions).• Absorbed power.

5.3.2 Check after first 50 hours – With the blower shut down, check:The oil level.

• Oil leaks.• Auxiliary circuit leaks.• Belt tension.

5.3.3 Check every 500 hours – With the blower shut down, check:The oil level.

• Oil viscosity and condition.• Belt wear.• Flexible coupling inserts.• Auxiliary circuits.

5.4 Stopping the blowerIf possible, remove the counter-pressure.

• Stop electric supply.

The blower can also be stopped in the presence of the counter-pressure but, because of the highcurrent absorption of the electric motor; problems with the electric circuit could result.

WARNING: Check that the deceleration of the blower is even and without vibrations.
