JIZZAX SUV HAVMOZIDAGI VORTEX SUV QUVURLARI QUVVATLARI ORQASIDAGI BOSIMNI TARQALISHNI MODELLASH

Rezervuarning vorteksli suv o'tkazgichlari eshigi yaqinidagi bosim taqsimotini o'rganish uchun o'ziga o'xshash usullar qo'llanildi, ular suv omboridan sezilarli darajada farq qiladi. Gidrostatik bosim. Suv o'tkazgich galereyasining pastki qismidagi piezometrik bosim va shift o'rtasidagi farq o'rnatildi, bu ma'lum bir xususiyatga ega va turli yo'llar bilan qonunlar bilan belgilanadi. Valf ostidagi bosim taqsimoti gidrostatik qonunga mos kelishi uchun o'rnatildi. Ammo valf ostidan oqib chiqadigan oqimning egri chizig'i tranzit oqimini kanalning pastki qismiga bosadigan markazdan qochma kuchlarni rag'batlantiradi, buning natijasida bu sohadagi bosim taqsimoti gidrostatikdan farq qiladi. Modellashtirish Jizzax suv omborining vorteks quvurlari darvozasi orqasidagi bosim ekanligini aniqladi, shuning uchun eshiklar orqasidagi bosim taqsimotini o'rganish alohida xususiyatga ega, chunki uning ta'siri ostida galereyalar va suv omborlari qoplamalariga yuk tushadi. darvoza o'zgaradi va hatto darvoza orqasida kavitatsiya hodisalari ehtimoli ham mavjud. Kavitatsiya hodisalari suv quvurlari eshigining eroziyasiga olib keladi.

Self-similar methods were used to study the pressure distribution near the gate of the vortex water conduits of the reservoir, which differ significantly fromhydrostatic pressure. The difference between the piezometric pressure at the bottom and the ceiling of the water conduit gallery has been established, which has a certain character and is established by laws in different ways. The pressure distribution below the valve was established to correspond to the hydrostatic law. But the curvature of the jet flowing out from under the valve stimulates centrifugal forces that press the transit flow to the bottom of the conduit, as a result of which the pressure distribution in this area differs from the hydrostatic one. Modeling has established that the pressures behind the gates of the vortex conduits of the Jizzakh reservoir are pressure, therefore, the study of the pressure distribution behind the gates has a special character, since under its influence the load on the lining of the galleries and the gate changes, and there is even the possibility of cavitation phenomena behind the gate. Cavitation phenomena lead to erosion of the water pipeline gate.
