Pressure chamber test

 

The Metrus test stands offer standard-compliant testing of shut-off and control valves of various sizes and shapes and are sometimes built and programmed according to customer-specific requirements.

(FIG 1 START)

 

The test sequence is similar for most test stands. The valve is filled with water, vacuumed, and refilled with water so that there is no more compressible air in the valve that could falsify the test result. Each type of test specimen has its own test parameters according to its size, shape and field of application. For example, there are different test pressures between 0-250 bar, different test periods and different permissible leakage quantities.

 

 

 

 

 

 

 

 

The pressure build-up is precisely adjusted to the test pressure via a pressure intensifier and control valves. During the test period, the leakage quantity is determined and decides on the test result.

All measurement data is logged and archived in a database. Printing of test reports is also possible, depending on the equipment.

All data important for the test are managed via corresponding recipes. Materials and standards are taken into account. An algorithm specially developed by Metrus calculates the required test pressure and time period in conjunction with the data sent by our control system, so that the tester does not have to deal with various tables to determine the correct values.

It was important for Metrus that the system be intuitive to operate and that the procedures be clearly laid out. (IMAGE 2 TEST1)

 

 

 

 

 

 

With our HMI design, the operator gets all relevant information such as start conditions, current test pressure, status of the running test and result displayed at a glance. The individual test steps are displayed in the sequence log with time stamp.

Another special request from Metrus for the new controls from INperfektion was the display, animation and operability of the hydraulics and pneumatics (FIGURE 3 MANUAL OPERATION).

Technical personnel can therefore control all relevant valves, pressure switches, cylinders, etc., as well as manually set test pressures, check lines for leaks, control cylinders and operate them without restriction. All valves, pressures, pressure switches, cylinder positions and lines are animated in color.

This is particularly helpful during commissioning, maintenance, repair or troubleshooting. The test sequence in automatic mode is also clearly displayed and provides a detailed overview of the valve circuit, pressure curves and air and water

lines.
