Description
Technical field
The utility model relates to a kind of temperature equalization system and autoclave, relates in particular to a kind of temperature equalization system for autoclave and autoclave.
Background technology
Autoclave molding is to produce Aeronautics and Astronautics with the important method of high fiber reinforced thermoset plastics high strength component, its technique mainly is that composite and relevant auxiliary material are put into mould, place autoclave, under vacuum (or antivacuum) state, pass through successively intensification, pressurization, insulation, cooling and decompression process, make the goods of satisfying the demand.Autoclave forming process has mould and simply reaches the advantage that product is closely knit, dimensional tolerance is little, voidage is low.
The capital equipment of autoclave molding is autoclave, heating and compression system and pumped vacuum systems.It is enough large that the tank inner chamber of autoclave is wanted, and can control the temperature in the tank body as required, and can bear enough pressure, and with the system that automatically records temperature and pressure.In addition, pumped vacuum systems also needs to suitable vacuum is provided in the chamber before and after product solidifies.Therefore, the seal of autoclave is directly connected to the stability of whole system (comprising pressure and temperature), and seal is decided by the air-tightness of each bonded block junction of tank body.For the temperature that makes tank interior in the autoclave molding course of work is even, also comprise temperature equalization system on the autoclave.
For middle-size and small-size autoclave, the higher small-sized autoclave of integrated level particularly, its common structure as shown in Figure 1, this type of autoclave operating pressure usually at 0.1MPa～10.0MPa, operating temperature at 50 ℃～500 ℃, the inner space of tank body 1 at 2L～100000L.The temperature equalization system of this middle-size and small-size autoclave generally comprises blower fan 2 and motor 3 as shown in Figure 1, and the blower fan 2 that arranges in the tank body drives by being arranged on the outer motor of tank body 3.
Process is to test and the analysis of the temperature equalization system of at present common several middle-size and small-size autoclaves, we find that they are that common electric machine (motor 3 as shown in Figure 1) directly is installed mostly outside autoclave, by the direct transmitting torque of power transmission shaft to the blower fan 2 in the autoclave, motor 3 drives blower fan 2 and rotates so that Air Flow blending in the tank, thereby make the interior temperature of autoclave even, referring to Fig. 2.Therefore as previously mentioned, the seal of autoclave is directly connected to the stability of whole system, in this type of prior art, often needs to guarantee power transmission shaft 5 and be installed in slipper seal between the support set 6 on the tank skin 7 of autoclave with encapsulant 4.If our test shows that temperature is no more than 170 ℃, the tank internal pressure is no more than 0.8MPa or continuous operation is no more than 10 hours, this slipper seal generally is safe; If but not satisfying above-mentioned condition (be temperature surpass 170 ℃, tank internal pressure surpass 0.8MPa or continuous operation above 10 hours), encapsulant 4 will be easy to generation performance to be changed and causes autoclave to leak gas.Encapsulant 4 adoptable best materials are commonly considered as fluorubber at present.According to bibliographical information, the high-temperature resistant of fluorubber is 250 ℃, the highest withstand voltage be 2.0MPa, its dynamic life time is for when temperature reaches 220 ℃, the life-span is 200 hours (if namely move 8 hours every day, service life less than 1 month).Yet the maximum temperature in the tank body of autoclave can reach 300 to 400 ℃, and is that have even higher, and the sealing ring that therefore uses fluorubber to make can not solve the sealing problem of autoclave well.
Owing to can not find at present can be under the above-mentioned condition of work long-time stable suitable encapsulant of retention, for preventing autoclave gas leakage, can only safeguard by the periodic replacement encapsulant at present, not only increase cost, and affected the utilization rate of autoclave.
