Open reactor

The reaction kettle body and the reaction kettle cover adopt the tapered surface and the arc surface line contact sealing form. Tighten the main bolts to press each other to achieve a good seal. When tightening the main bolts, the tightening torque must not exceed the range of 80-120NM. To prevent the sealing surface from being squeezed and overloaded, the sealing surface should be specially protected. When installing the reactor cover, the reactor cover should be started up and down slowly to prevent the sealing surface between the reaction kettle body and the reaction kettle cover Hit each other. To tighten the main nut, it must be tightened symmetrically and gradually in multiple times. The force must be uniform to achieve a good sealing effect.

The main parts of the autoclave-the cover (the whole forging is processed by the lathe after the flaw detection is qualified), the kettle body (the lathe is turned into a hollow after the whole forging is qualified for the flaw detection), the strong magnetic coupling stirrer, the high temperature and high pressure needle valve, the lower mixing part, the internal cooling The materials used for coils, temperature measurement parts, and submersible pipes are 0Cr18Ni9 (304), 0Cr18Ni10Ti (321), 00Cr17Ni14Mo2 (316L), titanium, Hastelloy, Monel, nickel, zirconium, tantalum, 904L, It is made of silver, tetrafluoro, etc., and can also be built-in titanium / Hastelloy / Monel / nickel / zirconium / tantalum / silver / tetrafluoride and other inner tanks, and can be sprayed with high temperature resistant tetrafluoride layer.
