  • Determine the fault maintenance method of IKO high temperature bearing in use

    introduction:High temperature bearing[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]In the course of its use, it shows strong regularity,And repeatability is very good。Normal high-quality bearings at the beginning of use,Vibration and noise are relatively small,But the spectrum is a little scattered,The amplitude is small,Probably due to some defect in the manufacturing process,Such as surface burrs。 shipment

  • Several misunderstandings of the quality of imported bearings are detected

    introduction: 1、Feel the bearing through the surface[bearing:bearing(“Bearing”,Japanese person“Axial receptor”)It is a part that holds and reduces the friction coefficient of load during mechanical transmission。Can also be said,When other parts move relative to each other on the shaft,A device used to reduce the coefficient of friction during power transmission and to keep the center of the shaft fixed。]Quality According to sales experience, many customers say that as long as the bearing surface is bright, the quality is good,This is wrong。The light of the bearing surface should be a kind of dark light,The reason for this dark is whether the steel used in the bearing is up to standard and its grinding worker

  • Chemical pump selection

    introduction:4.1.1Centrifugal pump The liquid viscosity is not greater than the conveying temperature650mm2/S,Otherwise, the efficiency of the pump decreases greatly。(When viscosity is greater than650mm2/Swhen,The performance of the centrifugal pump is greatly reduced,Generally do not choose centrifugal pump,But because the centrifugal pump infusion does not pulsate,No need for safety valves and simple flow regulation,Therefore, centrifugal pumps are often seen in chemical production for conveying viscosity1000mm2/SLiquid of...)。 Large flow,And the head is relatively low The dissolved or entrainment gas in the liquid is not greater than5%(volume) liquid
