  • Page 81: Dilution System Vkl 100 - Cleaning Suction Nozzle

    7  Maintenance Dilution system VKL 100 – cleaning suction nozzle The suction nozzle of the dilution system VKL 100 has a very small inner di- ameter and can become even more restricted due to salt residue. Restriction caused by salt particles severely impairs nozzle functioning. For this reason, remove the nozzle daily and clean it with compressed air.
  • Page 82 7  Maintenance Cleaning the nozzle Cleaning the nozzle with compressed air is usually sufficient. The nozzle can be cleaned in an ultrasound bath in the event of stubborn pollution. Recom- mended cleaning fluid: isopropanol. Cleaning suction nozzle with compressed air Installation Install the nozzle on the dilution system by reversing the order of removal, then connect the hose from the sampling tube to the suction nozzle.

Proceed as follows: Detach the quick coupling from the compressed air supply to depres- surize the test rig. Detach the side panel. Wait until the maintenance unit is completely depressurized, The manometer shows 0 bar.

    7  Maintenance Checking differential pressure The following procedure can be used to test the following things and others: • Check for leakage (e.g. at the seals or plug connections). • Check whether volume flow rate is calibrated correctly. • Check that the pump is working properly. Prerequisites The test rig has to be ready for operation.
  • Page 95 The measurement result must be within the tolerance indicated on the calibration certificate (“Allowable range”). If the result is not within the tolerance, there is leakage or some other fault. Contact Palas or your sales partner in this case. 6924-en_V1.3_09/20...

  • Page 96: Determining The Factor For Mass Concentration

    7  Maintenance Determining the factor for mass concentra- tion Objective The aerosol spectrometer Promo works with a factor for the mass concentra- tion. The factor has been set at the factory. It has to be checked or specified anew occasionally. Each type of aerosol (saline or oil) has its own factor. The two factors have to be determined one after the other and separately.
  • Page 97 7  Maintenance Prerequisites • The aerosol spectrometer Promo and the dilution system VKL 100 are switched on. • The liquid for which the factor for the mass concentration is to be deter- mined is contained in the aerosol generator. • The software PMFT1000 is closed. •...
