Oraliq chastotali nuqta payvandlash mashinalari uchun sovutish suvi sifatiga qanday talablar qo'yiladi?

Oraliq chastota uchun sovutish suvi sifatiga qanday talablar qo'yiladispotli payvandlash mashinalari? Umuman olganda, er osti va er usti suvlarida sulfat ionlari, silikat ionlari va fosfat ionlarining miqdori past, bikarbonat ionlari esa yuqori. Shuning uchun aylanma sovutish suvi tizimida ishlab chiqarilgan shkala asosan kaltsiy va magniyning karbonatidir. Bundan tashqari, kichik miqdordagi sulfat, silikat va kaltsiy va magniy fosfatlari ham mavjud.

O'rta chastotali nuqta payvandlash mashinasining Supero'tkazuvchilar sxemasining issiqlik uzatish koeffitsienti sirt maydoni shkalasi bilan bog'liq bo'lgani uchun, sirt shkalasi qanchalik qalinroq bo'lsa, issiqlik uzatish koeffitsienti shunchalik kichik bo'ladi. Odatda shkala qalinligi 2 mm dan oshmasligi kerak. Sovutish suvining tabiati va harorati shkala qalinligining o'sishiga bevosita ta'sir qiladi. , shuning uchun nuqta payvandlash uchun toza, qoldiqsiz, neytral va yumshoq suvdan foydalanishni tanlashingiz kerak.

Mashina sovutgichi uchun maxsus qoidalar quyidagilardan iborat:

1. Sovutish suvi neytralga yaqin, ya'ni vodorod ionining kontsentratsiyasi P qiymati 6,5-9,5;

2. Organik moddalar va to'xtatilgan mexanik aralashmalar ikkalasi ham ≤25 mg / L, yog' miqdori ≤5 mg / L.

3. Qattiqlik ≤10° (qattiqlik 1° 1 litr suvda 10 mg Ca0 yoki 7,19 mg Mg0 ga teng).

4. Rektifikatsiya rejasi Suvdagi kaltsiy ionlari kaltsiy karbonat hosil bo'lishining asosiy sababidir. Agar suvni yumshatish uchun suvdan kaltsiy va magniy ionlarini olib tashlash mumkin bo'lsa, kaltsiy karbonat kristallanmaydi va cho'kma hosil qilmaydi va shkala hosil bo'lmaydi.
