Air break
part used in dishwashers serves three main purposes. First, it measures the
washing water by means of a flowmeter provided in the air break inlet. Second,
it divides the washing water into two parts; one part is sent directly to the
tub and the other part is sent to the water softening system. Third, static
pressure needed in the salt-resin regeneration cycle is provided by the water
filled into the air break tank. Air break part is assembled to the dishwasher
tub using bolt and nut connection. During the assembly, crack initiation and
propagation are observed in the air break nut. In this paper, mechanical
behavior of the air break nut during the assembly is investigated by the
structural and fracture analyses using the finite element method. Alternative
designs for the air break nut are developed and compared with the current
design in order to examine the effect of its design on the stress distribution
and fracture behavior.

Bulaşık
makinelerinde kullanılan su cebi parçası üç ana amacı yerine getirir.
Birincisi, yıkama suyunu, su cebi girişinde sağlanan bir debimetre vasıtasıyla
ölçer. İkincisi, yıkama suyunu iki parçaya böler; bir kısım doğrudan küvete,
diğer kısım su yumuşatma sistemine gönderilir. Üçüncüsü, tuz reçinesi
rejenerasyon döngüsünde ihtiyaç duyulan statik basınç, su cebi tankına
doldurulan su ile sağlanır. Su cebi parçası, cıvata ve somun bağlantısı
kullanılarak bulaşık makinesinin küvetine monte edilir. Montaj esnasında, su
cebi somununda çatlak oluşumu ve ilerlemesi gözlenmektedir. Bu makalede, sonlu
elemanlar yöntemi kullanılarak yapısal ve kırılma analizleri ile su cebi
somununun mekanik davranışı incelenmektedir. Su cebi somunu için alternatif
tasarımlar geliştirilmiş ve tasarımların gerilme dağılımı ve kırılma davranışı
üzerindeki etkisini incelemek üzere mevcut tasarımla karşılaştırılmıştır.
