Cad is cúis le pléascadh téitheoir eite?

{1. Cúiseanna inmheánacha:

The power design of the electric heating tube is too large, the surface load is large, and the surface load is large. The surface temperature of the electric heating tube will rise, and the internal temperature will also rise. When the internal temperature of the electric heating tube is high to a certain extent, the electric heating tube will expand due to thermal expansion and contraction, and the electric heating tube will explode, which is called pléascadh .

When heating corrosive liquids with electric heating tubes, the material must be selected correctly. The corrosive liquid will slowly corrode the wall of the electric heating tube, causing small sand eyes. At this time, the electric heating tube is always powered on for heating, and the electric heating tube is prone to explosion due to thermal expansion and contraction.

The wall thickness requirements of electric heating tubes used in high-pressure environments are relatively high, basically seamless tubes with a wall thickness greater than 1.0mm. However, in order to reduce costs, some customers use welded pipes. When the electric heating is turned on, under the action of pressure, the electric heating tube is prone to small cracks, resulting in pléascadh feadán.

{2. Cúiseanna seachtracha:

Nuair a mhéadaíonn voltas an téitheoir eite, méadaíonn ualach dromchla an fheadáin téimh leictrigh, agus pléascann an feadán téimh leictreach . Is iad na cúiseanna thuas .

Dá bhrí sin, is iad na cúiseanna coitianta a bhaineann le pléascanna feadán téimh leictrigh na pointí thuas {. a fhad is a tháirgeann déantúsóir feadán téimh leictrigh ghairmiúil an feadán téimh leictrigh, tá an dearadh soláthair cumhachta réasúnta, tá an roghnú ábhair ceart, agus tá na treoracha sreangaithe agus suiteála ceart, ní thaispeánfaidh an feadán téimh leictrigh .,
