How to choose the appropriate sealing method introduction
1. First of all, the basis for clear sealing should be clearly selected: the first is the working pressure in the kettle, and the second is the nature of the working materials. There is also one of the operating temperatures of the equipment.
2. It is not necessary to clarify the type of seal used in stainless steel reactors: the seals used in reactors are commonly referred to as shaft seals. The first is packing seals, the second is mechanical seals, and the mechanical seals are divided into single-machine seals ( That is, single-end mechanical seal) and double-machine seal (ie double-face mechanical seal), the single-machine seal complete set also includes water jacket, double-machine seal is more messy, water removal jacket (requires circulating cooling water), also includes Supporting brackets, balance tanks, etc. Seals
3. How to choose the appropriate seal: Under normal temperature and pressure, the material is not volatile and not flammable and explosive, the packing should be selected; at a pressure less than 4 kg, the material is volatile and flammable and explosive. Under the application conditions, it is necessary to select a single machine seal; when the operating pressure exceeds 4 kg (but less than 10 kg), the material is volatile and flammable and explosive, it is necessary to select the double machine seal. . Seals
4. Advantages and Disadvantages of Various Seals: Packing seals are the cheapest, but only suitable for the most general operating conditions and materials; single machine seals are moderately priced and can be used under most operating conditions; double machine seals are the most expensive, but strict It is necessary to use it under harsh working conditions. Seals
5. According to the detailed application conditions, it is the most important: if you choose the double machine seal with the packing seal or single machine seal, it will form unnecessary quotation on the quotation; if it is necessary to select the double machine In the case of sealing, the choice of packing seal or single machine seal will leave a serious danger to future production safety and economic benefits. Therefore, it is especially important to select the appropriate sealing method according to the application conditions, and to determine the appropriate sealing method, which can ensure satisfactory application conditions and prevent unnecessary dross.
