Brief technical description
This plant is used for the pressure testing of single fire extinguisher
cylinders and propellant air bottles with a test pressure up to 500 bar.
Pressure testing is necessary to ensure safety by testing the cylinders
regularly. Testing pressure as a rule is 1.3 - 1.5 ( 5/3 ) times the allowed operating
pressure. Various specifically regulations and standards for each country have
to be observed.
The plants are equipped with a pneumatically driven high-pressure pump. In the
standard plant, the water is fed directly out of the main. As an alternative,
we also offer a water circulation with an appropriate receptacle and a
transfer pump. The advantage of the water circulation is that an emulsion may
be admixed to prevent corrosion inside the cylinders.
The cylinders are placed on a vertically adjustable table and retained by a
quick-acting clamping device. For propellant gas bottles the machine is
equipped with a fixed connection with suitable thread adapter.
Function
Propellant gas bottles to be tested are directly screwed into the suitable
thread adapter. Cylinders have to be equipped additionally with a fitting
according to the customer's requirements and are connected with quick-acting
couplings, installed at the pressure hoses. Afterwards the test cylinders are
filled completely with water by means of the mains water pressure or the
transfer pump. The air inside the bottle is let off through a relief tube. The
roll front should not be closed before water is running out without any
bubbles at the overflow nozzle.
After pressing the roll front switch, the pressure transformer may be switched
on. After reaching the test pressure the pressure transformer is cut off by a
pre adjusted contact switch at the pressure gauge.
For the following inside drying of the cylinders we offer our cylinder drying
device type BT 30. |
