Abstract:Osnovni problem merjenja hitrosti zrnc peska v peskalnem stroju je zelo velika abrazivnost peska in velika koncentracija prašnih delcev v zaprti testni napravi. Uporaba brezstičnih optičnih merilnih metod je zato pogosto nemogoča. Stične merilne metode so omejene na uporabo merilnikov, ki so zaščiteni z robustnimi oklepi. Kot alternativo robustnemu mehanskemu merilniku hitrosti zrnc peska smo razvili elektronski merilni sistem, ki ga odlikujeta dobra vodljivost vzdolž obeh prečnih osi curka peska in preprosta zgradba merilnega zaznavala, ki z uporabo cenenih elementov dovoljuje pogosto zamenjavo in ne potrebuje robustnega oklepa. V prispevku so predstavljeni razvoj, delovanje in uporaba mehanskega in elektronskega merilnega sistema. Prikazani so rezultati meritev in podana je primerjava obeh metod z razpravo in sklepi.

Title:A mechanical and electronic measurement system for particle velocity measurements in a shotblasting machine
Abstract:Two of the main problems for particle velocity measurement in a shotblasting machine are very abrasive shotblasting particles and a high concentration of dust within the closed testing chamber. The application of noncontacting optical methods is usually impossible and robust shields protecting the sensors from abrasion have to be used for contacting velocity measurements. An electronic measurement system has been developed as an alternative to the robust, mechanical measurement device. This alternative electronic system has a simple construction and uses low-cost elements that can be replaced very quickly and, therefore, no robust shields are necessary. This enables very good mobility and positioning of the sensor along both axes in a cross-section plane of a particle stream. The development, operation and application of this mechanical and electronic particle velocity measurement system are described in this paper. Experimental results are presented, discussed and both methods are compared.
