    1. Detailed information

    I. Overview

        Since balance multistage centrifugal pump is our self-developed products, such conventional pump structure type multistage centrifugal pump is a revolutionary innovation, multi-stage centrifugal canceled axial force balance mechanism, so that each pumping class media more secure. Especially when transporting gas and particles, high temperature medium or large range of operating conditions fluctuate frequently, completely avoid the traditional multi-stage centrifugal pump balance mechanism by frequent shifting, wear failure mechanism, steam resistance and other phenomena, this type of pump is me the company's high-pressure self-balancing segmental centrifugal pump (patent number: ZL03.2.35051.1) and high-pressure multistage centrifugal pump combination sealing device (patent number: ZL03.3502.X) patented technology, adding to its technical superiority.

       This type of pump is mainly used for medium conveying the truth, descaling hot-rolled steel, oil field water, crude oil, boiler feed water, mine drainage, coal mining and other occasions, for conveying solid concentrate is less than 5% wt, a particle size of less than 0.2mm physical properties similar to water or water of various media.


    Second, the structural characteristics of

        ZD pump also has a symmetrical unknown on a rotor member, two axial force of the impeller rotor components high and low pressure region cancel each other out and balanced, the instantaneous axial force pump running variable condition and residual spiral due to processing errors and sealing arising axial force borne by the thrust bearing means axis member, such pumps canceled balance balance disc or drum or the like axial force balance mechanism, completely avoiding the pump transient operating conditions change, or due to transport particulate media, or due to high temperature vapor barrier and so the balancing mechanism failure and a serious accident off axis, so that the bad condition of the pump which can run both in the stable.

         Pump body of the center bearing, high and low partition design, the force carrying splash lubrication or lubrication of plain bearings, the residual axial force by rolling bearing or thrust plate.

        See the pump body sealing and high-level low pressure area sealed off with long spiral seal, the seal is more reliable, especially in transport medium containing solid particles, less wear, long cycle to ensure reliable operation of the pump.

        Pump seal according to the characteristics of the transmission medium, the use of modular sealing: containing solid particles and efflux medium without polluting the environment, and sealed with a screw type polymer caulks composition, and to achieve sealing online maintenance: high temperature and corrosion medium, screw seal and mechanical seal combination patterns.
