Kev ua haujlwm siab ntawm lubmechanical foobrau 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.
Feem ntau nyob rau hauv kev xyaum ntawm mechanical seals rau pumps, lub siab ua hauj lwm siab tshaj 3 MPa, thiab lub foob sib npaug yog siv los xaiv ib tug sib npaug foob, thiab multi-theem foob tuaj yeem raug kaw thiab nqis los ntawm kauj ruam. Hom qauv (xws li multi-end mechanical sealing, thiab lwm yam) raug txiav txim siab. Feem ntau, muaj qhov tsis sib xws ntawm {{0}}} sib npaug ntawm 0.7 MPa hauv qab 0.7 MPa lossis tsawg dua cov khoom siv roj av. Nws kuj tseem tuaj yeem xaiv qhov tsis sib npaug ntawm qhov sib npaug ntawm tus nqi qis dua 6.6 mPa.m / s. Rau cov roj uas muaj qhov ntom ntom hauv qab {{10}}.6kg / L, nws yog sib npaug rau kev sib khi. Qhov sib npaug foob raug xaiv ntawm 0.2-0.33 MPa siab ntawm 0.2-0.33 MPa siab ntawm qhov tsis muaj viscosity thiab lubricity tsis zoo.
