Aksincha, klapan korpusi o&#039;nlab yillar davomida xizmat qilish uchun mo&#039;ljallangan statik bosim idishidir. Qaytarish komponentlari har bir klapan harakati bilan aylanadi, bu ularni yig&#039;ishdagi eng yuqori a\u015f\u0131nmaya bardoshli elementlarga aylantiradi.<\/p>\n<h3>Jarayonni o&#039;chirmasdan barcha aksessuarlarning nosozliklarini aniqlay olamanmi?<\/h3>\n<p>Aksariyat aksessuarlarning nosozliklarini onlayn ravishda aniqlash mumkin. Jarayon ishlayotgan paytda pozitsiyaning teskari aloqa siljishi, pozitsionerning havo sarfi o&#039;zgarishi, solenoid bobinining qarshilik siljishi va filtr regulyatorining bosim pasayishi aniqlanishi mumkin. Klapan korpusidagi muammolar \u2014 o&#039;rindiqning oqishi, vilkaning bog&#039;lanishi, bezakning shikastlanishi \u2014 odatda tasdiqlash uchun o&#039;chirishni talab qiladi.<\/p>\n<h3>Filtr regulyatori elementlarini qanchalik tez-tez almashtirishim kerak?<\/h3>\n<p>Filtr elementini almashtirish ishlab chiqaruvchining bosim differentsiali bo&#039;yicha tavsiyasiga muvofiq amalga oshirilishi kerak, odatda bosim pasayishi 5-10 psi dan oshganda. Amalda, rejalashtirilgan texnik xizmat ko&#039;rsatish vaqtida har chorakda almashtirish havo sifati bilan bog&#039;liq ko&#039;pgina nosozliklarning oldini oladi. Siqilgan havo sifati past bo&#039;lgan joylarni oylik almashtirish kerak bo&#039;lishi mumkin.<\/p>\n<h3>Boshqaruv klapanlarining ishdan chiqishida eng ko&#039;p uchraydigan noto&#039;g&#039;ri tashxis nima?<\/h3>\n<p>Klapan korpusi nosoz deb faraz qilsak. Texnik xizmat ko&#039;rsatish guruhlari ko&#039;pincha klapanni olib tashlash va ustaxonada ta&#039;mirlashni rejalashtirishadi, agar muammo siljish holatidagi teskari aloqa signali yoki tiqilib qolgan filtr regulyatori bo&#039;lsa. Aksessuarlarni 15 daqiqalik tekshiruv klapanni olib tashlash ishlariga sarflanadigan keraksiz ishlarni soatlab tejashga yordam beradi.<\/p>\n<h3>O&#039;rnatilgan har bir qurilma uchun zaxira solenoid klapanlarni saqlashim kerakmi?<\/h3>\n<p>Xavfsizlik halqalari uchun, ha \u2014 nosozliklar paytida ishlamay qolish vaqtini minimallashtirish uchun har bir halqa turi uchun kamida bitta zaxira nusxasini saqlang. Umumiy boshqaruv halqalari uchun keng tarqalgan solenoid klapan modellarining kichik bir qismini saqlang. Solenoid klapanlarning arzonligi ($200\u2013$500) buni rejalashtirilmagan o&#039;chirishlardan amaliy sug&#039;urta qiladi.<\/p>\n<h2 id=\"bottom-line\">Xulosa<\/h2>\n<ul>\n<li>Klapan korpusining nosozliklari faqat 16% boshqaruv klapanidagi muammolarni ifodalaydi.
