OPERATION

Once the gas booster has been set up and the initial start up is completed, operation is very simple.

There are two possible operator actions:

•

Setting the booster output pressure (see Section 3.2.1).

•

Turning the booster ON and OFF (see Section 3.2.2).

3.2.1

Depending on the drive pressure set by the DRIVE ADJUST regulator, GB-152-AF may

generate pressure over 70 MPa (10 000 psi). To limit the maximum pressure that can be

generated by the booster, limit the drive air supply to the Drive Air Control Kit to 75 psi (500 kPa)

(see Section 2.3.2.1).

The booster output pressure is determined by the value of the drive air pressure. The

approximate booster output will be the drive air pressure times 152.

To set the drive air pressure, adjust the DRIVE ADJUST regulator:

With the SHUTOFF valve in the ON position, adjust the regulator counterclockwise while

observing the DRIVE gauge to decrease pressure to a value lower than the desired set

pressure. This is necessary because the regulator is not self-venting.

Put the SHUTOFF valve in the OFF position.

Rotate the DRIVE ADJUST regulator knob clockwise while observing the set pressure on

the DRIVE gauge. Set the drive pressure to the maximum desired high pressure output

divided by the booster ratio (152:1). For example, if the desired high pressure output of

the GB-152-AF is 10 000 psi, set the drive air pressure to 10000/152 = 66 psi.

Remember that when the SHUTOFF valve is in the ON position, the booster will operate

until the high pressure output is equal to the drive air setting times the booster ratio.

To correctly set the pressure, gas flow must not occur. If flow is present in the circuit when

the regulator is adjusted, the pressure will increase when flow is reduced. If the setpoint is

exceeded, see Section 3.2.2.

The booster will run automatically, continuously until the high pressure output is equal to

the drive pressure times 152. Set the drive pressure very carefully to avoid generating higher

output pressures than desired which could be dangerous. Do not apply more than 10 000 psi (70

MPa) to the GPC1-10000-AF SUPPLY port.
