Pressure vessel with quick-opening door, certified to Chinese Pressure Vessel Code. The certificate is GB150-2011

2. Quick Closing Doors

Ø  The whole system consists of four parts: a pair of gear flange, driven devices, seal ring and high temperature protection system. Ø  Hydraulic operated door opening, closing and locking. It is controlled by PLC system. Ø  The seal ring is made of silicon rubber, high temperature resistance. Ø  It can be manual operated by the switches on the electrical cabinet near the door also. Ø  Door type: Opening left side. (facing the door

3. General Structure


Autoclave Carbon Fiber Machine

4. Insulation System

Ø  Insulation:internal insulation Ø  Insulation material:ceramic fiber Ø  Internal sheet metal: stainless steel, 1.0 mm Ø  Insulation thickness:100 mm

5. Floor supports and rails

Ø  Rail loading:4000kg,Increased loading can be offered optionally. Ø  Rail type::equal angle steel Ø  Floor loading::400kg,Increased loading can be offered optionally. Ø  Form of floor supports : riffled plate (4mm)

6. Heating System

Ø  The heating system consists of three heating zones and the heating elements located in the bottom of the vessel for easy maintenance. Ø  Electric heating, inconel tubular heaters Ø  Multiple banks controlled via thyristor SCR. Ø  Proportional control, 0-100% output. Ø  The heating process is controlled by temperature controller, the mode is PID control, and it is organized by PLC system.

7. Pressure components

Ø  Inlet and exhaust valve, proportionally controlled, electro-pneumatic adjustable ball valve. Ø  Manual exhaust valve, 3-piece ball valve. Ø  Exhaust silencer (Sounder absorber) makes the noise less than 70DB. 1 pc

Ø  Pressure transducer: 1   Accuracy: +/- 50mbar (0.005Mpa)  Ø  Pressure gauge:1 Ø  Pressure control tolerance:±0.1bar

8. Cooling system (heating exchanger)

Ø  The heat exchanger is located in the bottom of the autoclave for easy maintenance. Ø  Stainless-steel heat exchanger, all internal wetted parts stainless-steel. Multi-row finned tubing. Ø  Proportionally cooling valve for main cooling control. Ø  Air spray and Mist water valves for pre-cooling control.

9. Forced convection system (Air-circulation System)

Ø  Hot air channel

Our Composite Autoclave is different from the conventional autoclaves. It does not require a radial air-duct and instead utilizes the floor as the forward air delivery system. This unique design features decrease the cost for customer, and make the temperature more uniform.

Ø  The Motor fan for circulation:The motor is bolted to the body of the autoclave, it drives the fan directly.

Ø  Main parameters of circulating motor fan:Power:18.5KW,Frequency conversion control   Connecting format:direct-connected,  Rated rotate speed:960r/min(400V/50HZ),  Fan wheel:6# centrifugal impeller, wind pressure:1050Pa, Flow rate:8900M3/h.

Ø  Shaft sealing and cooling

Fully sealed special motor, bearings with SKF high-temperature series. The structure is easy to maintenance. Working use of water cooling, the shaft water cooling with separate water pump and flow switch to be fitted to monitor water flow and automatically alarm/stop the cycle if there is not enough water flow.

10. Temperature monitoring components

Ø  Temperature control tolerance:±2°C  Ø  Air temperature thermocouples: 1pc ,fixed Type-K, including PC monitoring/ control,data-acquisition  Ø  Hi-Limit safety thermocouple: 1pc,  fixed Type-K, including PC monitoring/ control Ø  Part thermocouple:20pcs, can be movable Type-K, including PC monitoring, data-acquisition, and control.

11. Vacuum system

11-1   Vacuum source ports: 10pcs total 

11-2   Each source port will include:

Ø  ½" internal thread pipe joint Ø  External manual blocking valve, 3- piece ball valve, stainless-steel Ø  PC-controlled vacuum select valve, 3-piece ball valve, stainless-steel. Ø  PC-controlled vent-vent select valve, 3-piece ball valve, stainless-steel. Ø  Stainless-steel tubing, ¼"

11-3   Vacuum transducer ports: 10pcs total

11-4   Each Vacuum transducer port will include:

Ø  ½" internal thread pipe joint Ø  External manual blocking valve, 3-piece ball valve, stainless-steel Ø  Stainless-steel tubing, ½"

11-5   Vacuum Transducer: 11pcs total

Ø  Proof pressure: 15Bar Ø  Range:-760mm Hg to 15 bar Ø  Accuracy: +/- 15.6mm Hg

11-6 Vacuum filter: 11pcs total

For composite curing applications with high volatile content (ie. high-temperature polyimides), the vacuum filter will be much more effective condensing volatiles and solvents during high-temperature curing operations.

11-7   Each vacuum source individually controlled, it can be done vacuum and vent. And each will be individual shut off in case of vacuum bag rupture.

11-8  Separation of vacuuming and measuring.

11-9  Automatic vacuum leakage test before start a circle.

12. Lightning System:Lightning throughout the autoclave working area, it is 400 lux.

13 Control System

Ø  The Control System is developed based on the research and development toward composite material field, and it is made up of one PLC for the automatic managing of the process and one PC for the supervision of the system. The operation of the whole system is based on the exclusive developed software package-TPC(Thermal processing control).

Ø  Password protected entry access, operator can log into the system by accessing the security login form with a name and password.

Ø  Full automatic operation including heating, pressuring, vacuum, vent, cooling and exhaust actions. Monitoring and display run status information, data saving information, integrity check information and run override controls, such as change segment, end run, etc.

Ø  Manual operation screen allows operator take manual control temperature, pressure, vacuum, fan, and valves as allowed.

Ø  According to the different working process requirement, it can set segment time, control TC, temperature value, temperature rate, vacuum value, pressure value, pressure rate, etc. before curing, and it also can modify the parameter on live operation.

Ø  It can choose and save the different curing recipe, display a real time and historical trend of the pressure, vacuum and temperature; storage all processing data and its paperless record function can realize reporting of working curve and process parameters.

Ø  It can monitor all actions of devices and the safety system information continuously, such as safety interlock, door closed, door locked and so on.

Ø  It has audible and visual alarm system and diagnostic and fault finding screen, including over-temperature and over-pressure alarm and various safety protection functions, such as vacuum leakage, over cure cycle deviations, component failure, etc.

Ø  Heating control will allow operator to control from product or air or minimal T/C reading, the TPC has control TC, operator can choose air TC, High TC, or low TC.

Ø  Customer can operate register, login and typing in product information, and realize intranet or remote control.

Ø  It can realize data output, printing, analyzing requirements to improve product quality.

Ø  UPS (uninterruptible power supply), power:1000VA

14. Safety systems:

Ø  Mechanical and electrical interlocks for door closure, door closed and locked proof of position, the autoclave can not be opened when pressure in the autoclave higher than 0.2 bar.

Ø  It will be auto-alarm when facing over-temperature or over-pressure; auto drop the temperature when over temperature, and auto-release when over pressure.

Ø  It has emergency valve for pressure release.

Ø  Pressure safety relief valve, certified to CE

Ø  Low supply air pressure alarm, low pressure switch and low pressure relief...

Ø  Circulation fan motor tripped indication.

Ø  Audio visual alarm when door opening closing is in operation.

Ø  Emergency stop push button to abort the cure cycle all pressure control valves, depressurization control valves, main cooling will fail to safe.

15. Paint:Our autoclave will be primed and painted high-gloss "Dark Blue" color. Customer requested color can be quoted optionally.
