5.2 Injecting
Job
You want to begin injecting.
Prerequisite
➤
You have prepared the unit according to chapters 4 and 5.
➤
Appropriate packers are available for the injection lance.
Procedure
1.
Set the required packers into the wall which is to be injected.
2.
Connect the injection lance nipple to a packer.
3.
Set the required injection pressure using the air pressure regulato.
The injection pressure is calculated as follows:
The pressure set with the injection pump‘s regulating screw (visible on
the pressure gaugeture) is multiplied by pressure ratio.
Example:
Pressure setting (pressure gauge reading) 4 bar
pressure ratio (Multiplier)
33
=> 4 bar x 33 = 132 bar
The material is injected at132 bar.
4.
Open the injection lance ball valve.
The injection material is now pumped into the foreseen location.
Fill the injection hole with as little pressure as possible to ensure the
maximum safety to operating personnel and the masonry structure. When
the hole is filled (pressure equalization), the pump will stop automatically.
Now. raise the injection pressure to the material manufacturer‘s
recommendation. Once pressure equalization is reached again, the pump
will stop automatically and the area to be injection is filled completely.
5.
Adjust back the air regulator by turning the control screw to the left.
6.
Close the injection lance.
7.
Disconnect the injection lance nipple from the packer.
