[ Industry News ] Anticorrosion knowledge of mechanical seal for kettle

Corrosion prevention of mechanical seal for kettle is very important. Today, I would like to share some common knowledge about corrosion prevention of non-metallic rings: 1. Graphite ring corrosion. There are three reasons for the corrosion of resin impregnated impermeable graphite ring: first, when the end surface is overheated and the temperature is greater than 180oC, the impregnated resin will break away from the graphite ring, reducing the wear resistance of the ring; Second, if the impregnated resin is not properly selected

[ Industry News ] Features of reactor sealing device

Characteristics of reactor sealing device Understand the characteristics of different types of reactors to master the key points of mechanical seal design. 1. From the lubrication point of view, the mechanical seal used for the plug-in reaction kettle at the side of the mixing shaft generally does not have the problem of poor lubrication, and the liquid level of the medium in the kettle must be kept at a certain height. For the reaction kettle with shaft protruding from one side, the shaft is in cantilever state, so it is easy to produce

[ common problem ] What is the difference between the mechanical seal of agitator kettle and the mechanical seal of pump?

The mechanical seal is a mechanical part used to seal the rotating shaft and the stationary pump chamber. The sealed part is a cylindrical area, the shaft in the equipment rotates and penetrates inside and outside the equipment, and the body part is still and full of fluid medium inside. Driven by pressure difference, concentration difference and temperature difference, fluids inside and outside the equipment exchange with each other; "Sealing" means to control the fluid exchange between internal and external areas, so that“
