MAQOLA ANNOTATSIYASI

Iste’molchilar, deb hisoblanadigan meliorativ nasos stansiyalarining nasos qurilmalari uchun avtomatlashtirish faqat elektr ta’minoti ishonchliligini ancha oshirish imkonini beradigan nasos agregatlarini o‘z-o‘zidan ishga tushirish jarayoni amalga oshirilgandagina tegishli samarani beradi. O‘z-o‘zidan ishga tushirish nazariyasi hozirgi vaqtda amaliyot taqdim etadigan vazifalarini hal qilishga imkon beradigan darajagacha ishlab chiqilgan. Meliorativ nasos stansiyalari nasos qurilmasining o‘z-o‘zidan ishga tushishini tadqiq etishda yuritma yo‘qotilganida va o‘z-o‘zidan ishga tushishga o‘tishda nasos agregatining statik va dinamik rejimlarini hisoblash uslubini ishlab chiqish bilan bog‘liq masalalarni hal qilish, shuningdek elektron hisoblash mashinalarini qo‘llab tizimning gidromexanik va gidravlik o‘tish jarayonlarini hisoblash katta ahamiyatga ega. Sug‘orish uchun suvni mashinalar bilan ko‘tarib berishning rivojlanishi elektr tizimlarida bu elektr iste’molchilarining solishtirma salmog‘i keskin, hatto shu darajada oshishiga olib keldiki, natijada mashinalarda sug‘orish energiya tizimining ish rejimi va energetika balansiga muhim ta’sir ko‘rsata boshladi. Sug‘orish nasos stansiyalarining elektr iste’moli holatini tahlil qilish anchagina zaxiralar mavjudligini ko‘rsatadi, bu zaxiralar nasos stansiyalarining konstruksiya xususiyatlari va ularning qanday maqsadlar uchun mo‘ljallanganligiga bog‘liq holda o‘rtacha 15% gacha, ayrim hollarda 18—20% gacha yetadi. Elektr energiya asosan nasoslarning elektr yuritmalari orqali sarflanar ekan, demak elektr energiyadan oqilona foydalanish masalalarini elektr yuritmaning energiya tejovchi vositalari bilan hal qilish zarur bo‘ladi.Suvni ko‘taruvchi nasos stansiyasining vazifasi, uning oqim tezligidan qat’i nazar belgilangan bosimini ushlab turishdir va bu ko‘pgina shartlarga bog‘liq bo‘ladi. Suvni ko‘taruvchi nasos stansiyalari maksimal bosimni hosil qilish uchun mo‘ljallangan. Shuni hisobga olgan holda, nasos agregatlarining har xil bosimda ishlashini ta’minlaydigan boshqarish usullari talab qilinadi.
