On the choice of mixing and sealing in reaction kettle attaches to the sealing effect, use safety, and cost savings appear particularly important.1. First of all, the basis of a clear seal choice: the first is the working pressure inside the kettle, the second is the nature of the work material.Another is the working temperature of the equipment.2. Secondly, we must make clear the category of stainless steel used in the reaction kettle seal: the shaft seal used in reaction kettle seal known as there are two kinds, the first is packing seal, the second is the mechanical seal, mechanical seal is divided into single seal (that is, the single mechanical seal) and double machine (i.e., double mechanical seal), single machine complete set also includes water jacket, double machine seal is more complex, in addition to the water jacket (must have a circulating cooling water), also include supporting bracket, tank, etc.3. How to choose the suitable seal: at atmospheric pressure, no volatile and flammable and explosive materials under the conditions of use, should choose packing seal;In pressure is less than 4 kg, volatile and flammable and explosive materials easily under general conditions of use, will choose single seal;In the pressure of work more than 4 kg (but less than 10 kg), volatile and flammable and explosive materials easily under the condition of the use of the strong, must choose double machine.4. The advantages and disadvantages of all kinds of sealing: packing seal the cheapest price, but only for the use of the most common conditions and materials;Single price moderate, gm can be used in most condition;Double machine most expensive, but must be used under harsh working conditions.
