Diafragma bosim o'lchagichi aslida ish paytida ish muhitining haroratiga ma'lum talablarga ega. Agar diafragma bosim o'lchagichi juda yuqori haroratli muhitda ishlatilsa, u ham yomon ta'sirga ega bo'ladi. Shunday qilib, har bir kishi birinchi navbatda diafragma bosim o'lchagichining qancha haroratga bardosh berishi mumkinligini aniqlaydi. Xo'sh, diafragma bosim o'lchagichining issiqlikka chidamli harorati qanday?
In the standards of various diaphragm pressure gauges in our country, generally only the normal working environment temperature of the diaphragm pressure gauge is specified. For example, the general diaphragm pressure gauge is -40-70 degrees, and the diaphragm pressure gauge is -25-55 degrees, but there is no regulation. The heat-resistant temperature.
Although there are diaphragm pressure gauge factories that produce heat-resistant diaphragm pressure gauges or high-temperature diaphragm pressure gauges, few manufacturers of diaphragm pressure gauges clearly indicate the heat-resistant temperature or high-temperature temperature of diaphragm pressure gauges. This also makes users of diaphragm pressure gauges feel embarrassed.
Issiqlikka chidamli diafragma bosim o'lchagich yoki zanglamaydigan po'latdan yuqori haroratga chidamli diafragma bosim o'lchagich deb ataladigan ish harorati qanday? Bu ish muhiti yoki o'lchangan o'rtacha haroratmi?
Bu erda birinchi navbatda payvandlash paytida turli xil zanglamaydigan po'latdan yasalgan diafragma bosim o'lchagichli kamon naychalarining payvandlash haroratini tushunishimiz kerak, ular:
Brazing (tin soldering), the temperature is 120 degrees during welding, and is mostly used for welding copper joints and copper spring tubes.
Kumush payvandlash, payvandlash paytida 600 daraja haroratda, ko'pincha mis bo'g'inlari va zanglamaydigan po'latdan yasalgan kamon quvurlarini payvandlash uchun ishlatiladi.
Argon boshq manbai, payvandlash harorati 1500 daraja, u asosan po'lat bo'g'inlar va zanglamaydigan po'latdan yasalgan kamon quvurlarini payvandlash uchun ishlatiladi.
Shunday qilib, umuman olganda, diafragma bosim o'lchagichining bahor trubkasini payvandlash usulini bilsangiz, diafragma bosim o'lchagichi bardosh bera oladigan muhit haroratini ham bilishingiz mumkin, ya'ni: lehimli diafragma bosim o'lchagichi odatda 120 dan past darajada ishlashi mumkin. daraja, kumush payvandlash Tipi diafragma bosim o'lchagichi odatda 600 darajadan past darajada ishlashi mumkin va argon boshq manba tipidagi diafragma bosim o'lchagichi odatda 1500 darajadan past bo'lishi mumkin.
Bundan tashqari, issiqlikka chidamli diafragma bosim o'lchagichlari yoki yuqori haroratga chidamli diafragma bosim o'lchagichlarida ishlatiladigan ba'zi komponentlarning materiallari uchun ma'lum talablar mavjud. Masalan, diafragma bosim o'lchagichlari uchun qistirma plastmassadan tayyorlanmasligi kerak, lekin alyuminiy yoki boshqa yuqori haroratga chidamli materiallardan foydalanish kerak; Diafragma bosim o'lchagichining siferblatasi plastik plastinka emas, balki alyuminiy plastinka yoki temir siferblatdan foydalanishi kerak. Chunki yuqori haroratlarda plastik astar va siferblat deformatsiyalanadi va ko'rsatgichning ishlashiga ta'sir qiladi, bu esa diafragma bosim o'lchagichining funktsiyasini yo'qotadi.
