The structure and working principle of an autoclave

Autoclave It consists of components such as a reaction vessel, magnetic stirrer, electric heating furnace, safety rupture disc, needle valve, and control box.

Autoclave Made of stainless steel or special materials according to user requirements. The reactor body is connected to the flange via a threaded joint, and the reactor lid is bolted to the flange. The spherical surface on the reactor lid and the conical surface on the reactor body form a line-contact seal without the need for gaskets.

The magnetically driven stirrer is mounted on the top surface of the kettle lid. The stirring shaft extends into the reactor through a central hole. The motor is driven by a V-belt, which transmits power to the external permanent magnet located inside the aluminum pulley. The magnetic field of the external electromagnet passes through the sealing cover, causing the internal electromagnet to rotate.

The top of the magnetic-drive stirrer is equipped with an inductive speed-sensing electromagnet and a speed-sensing element. The operating speed of the stirring shaft inside the reactor is reflected via the control box.

The pressure gauge and rupture disc, the inlet (liquid) valve, and the sampling (exhaust) valve are installed on the lid of the autoclave. Cooling water pipe fittings and high-temperature platinum resistance thermometers. When purchasing, rupture discs are typically set according to the user’s operating pressure. When the user exceeds the specified pressure during operation, sandblasting and pressure relief will occur to protect the safety of other pressurized components. The heating furnace uses a spiral electric heating element. The electric heating tube secures the resistance wire within an insulating material via a shrinking process, offering excellent insulation performance and a long service life.

Autoclave Equipped with a control box, by regulating the speed of the DC motor, it is possible to achieve from... 0 To 1100 Variable-speed transmission. By means of PID The control system connects the temperature controller in the control box to the platinum resistance thermometer inserted into the pot body, enabling a tolerance of ± 0.2 Precision target temperature control at % accuracy.
