23、tage ignition device unit that generates a high voltage (kV) and low current (mA) between the electrodes of the plasma spraying torch in order to ignite the arc 4 Principles of acceptance inspection 4.1 General The following clauses reveal state of the art technology in thermal spray equipment and t

24、he minimum requirements concerning a stable parameter setting and maintenance according to the classes given in Annex A. 4.2 High-voltage ignition device Other components and functions of the spraying equipment and other machines and/or equipment operated near by to the spraying equipment shall not

25、be affected by operation of the high-voltage ignition device. 4.3 Plasma gases The plasma spraying equipment shall be designed and installed in such a manner, that safe operation with plasma gases specified by the user will be achieved. 4.4 Plasma spray nozzle Processing of the spraying powder shall

26、 be possible without producing any disturbing deposits on and/or in the nozzle. Nozzles with different shapes and powder ports (internal or external) may be used for special applications. This standard may only be used and printed by approved subscription and freemailing clients of the SABS.EN 1395-

27、4:2007 (E) 5 4.5 Spraying powder feed unit The powder feed unit shall be suitable for operation with the spraying equipment to be taken. The unit shall permit uniform processing of the powder required. It shall be possible to adjust the powder feed rate. The set points shall be constant and reproduc

28、ible, which is a precondition for this being adequate and constant carrier gas pressure and flow. 5 Procedure of acceptance inspection 5.1 General Spraying equipment shall be deemed properly supplied for all suitable spraying applications and for use with all suitable spraying materials required for

29、 the spraying process if it complies with the following requirements: 5.2 Electrical power Proof of the power rating required shall be given by 20 min of spraying with the parameters for aluminium oxide according to EN 1274:2004, 12.1 as recommended by the equipment manufacturer. During the test, th

30、e following items will be examined: electrical control; gas control; cooling water temperature. Limits of deviation: see Annex A; Class A and Class B. After stabilisation of arc and plasma, the deviation of the voltage (variable parameter) from the set point shall not exceed 3 % (Class A) and 12 % (

31、Class B). 5.3 High-voltage ignition device The high-voltage ignition device shall be deemed to meet the requirements given in 4.2 if it does not interfere with any appliances and functions of the spraying equipment during the test as specified in 5.2. There should be no excessive erosion wear visibl

32、e on the nozzle (spark). 5.4 Plasma gases The system shall be deemed to comply with the specified requirements if the following requirements are satisfied by the acceptance inspection. The values of gas pressure and gas flow shall not deviate by more than 1,5 % (Class A) and 5 % (Class B) from the s

33、et points over a 20 min period of spraying. If the secondary gas is the variable parameter, the deviations from the set point shall not exceed 3 % (Class A) and 12 % (Class B) after stabilisation. Setting the primary gas pressure and/or flow rate shall not affect the corresponding values of the seco

34、ndary gas and carrier gas and vice versa. 5.5 Plasma spray nozzle The nozzle shall be deemed to comply with the requirements specified in 4.4 if there are no disturbing deposits of spraying material on or in the nozzle when testing as specified in 5.2.
