Problems solved by technology

However, the maximum temperature in the tank of the autoclave can reach 300 to 400 ° C, and some are even higher, so the sealing ring made of fluorine rubber cannot solve the sealing problem of the autoclave well.
[0006] Since there is currently no suitable sealing material that can maintain stable performance under the above-mentioned working conditions for a long time, in order to prevent air leakage in the autoclave, at present, the only way to maintain it is to replace the sealing material regularly, which not only increases the cost, but also affects Utilization of the autoclave

Abstract

The invention provides a temperature equalizing system for an autoclave. The temperature equalizing system comprises a fan and a motor; the fan is arranged inside a tank body of the autoclave; the motor is arranged outside the tank body; the motor is provided with a first magnetic body; the fan is provided with a second magnetic body matched with the first magnetic body, and the first magnetic body and the second magnetic body are arranged to enable the motor to drive the fan through the magnetic force between the first magnetic body and the second magnetic body. The invention also provides a temperature equalizing method for the autoclave. According to the temperature equalizing system and method for the autoclave disclosed by the invention, transmission from the motor to the fan is achieved by the magnetic force, thereby reliably sealing the autoclave in the temperature equalizing operation of the autoclave without a sealing material.

Description

technical field [0001] The invention relates to a temperature equalizing system and method, in particular to a temperature equalizing system and method for autoclaves. Background technique [0002] Autoclave molding is an important method for producing high-strength components of high-fiber-reinforced thermosetting plastics used in aviation and aerospace. Its process is mainly to put composite materials and related auxiliary materials into the mold, place them in an autoclave, and vacuum (or In the state of non-vacuum), the products that meet the needs are made through the processes of heating, pressurizing, heat preservation, cooling and decompression in sequence. The autoclave molding process has the advantages of simple molds, compact parts, small dimensional tolerances, and low void ratios. [0003] The main equipment for autoclave forming is autoclave, heating and pressurizing system and vacuum system. The tank cavity of the autoclave should be large enough to control...
