Ishlash bosimimexanik muhruchun pumps is the pressure of the sealing interior sealing medium. Since the sealing indoor medium pressure is not equal to the working pressure of the pump, the mechanical seal work pressure is equal to or lower than the working pressure of the pump, so the sealing operation pressure is determined according to the structure of the pump. For example, the single-stage cantilever pump should think of an imbalance hole or a back blade according to the multi-stage pump level, according to the installation of the multi-stage pump level.
Odatda mexanik muhr amaliyotidas uchun pumps, ish bosimi 3 MPa dan yuqori va muvozanat muhri muvozanatli muhrni tanlash uchun ishlatiladi va ko'p bosqichli muhr muhrlanishi va bosqichma-bosqich pastga tushishi mumkin. Strukturaviy tur (masalan, koʻp-mexanik muhrlash va boshqalar) hisobga olinadi. Odatda, benzin tovaridan {{0}}bo'lmagan muvozanat muhri 0.7 MPa 0.7 MPa dan past yoki undan kamroq. Shuningdek, 6,6 mPa.m/s dan kam boʻlgan -muvozanatsiz muhrni tanlash mumkin. Zichligi {{10}},6kg/l dan pastroq boʻlgan moylar uchun u muhrlanish uchun tenglashtiriladi. Balanslangan muhr past viskoziteli va kambag'al moylash 0,2-0,33 MPa bosim da 0,2-0,33 MPa bosim tanlangan.
