The system structure of vacuum hot pressing furnace
Vacuum hot pressing furnace is composed of several mechanical systems, as follows:
Consists of oil diffusion pump, roots pump, mechanical pump and electromagnetic pressure differential valve (prevent due to sudden power failure, mechanical pump oil flow backward) charging valve, relief valve, butterfly valve, vacuum vacuum pressure gauge (plus or minus Pa) corrugated pipe, vacuum tubes and bracket, etc.
2. Hydraulic system:
Adopt electric input mode. By hydraulic station is equipped with imported proportional valve, pressure sensor, displacement monitor using grating ruler ranging accuracy (0.02 mm), and the hydraulic cylinder hydraulic equipment, pressure half automation, can be adjusted by manual adjustment. The instrument can be set to adjust the pressure automatically, and can achieve stable pressure and pressure.
3. Water cooling system:
It is composed of all kinds of valve pipe related devices and equipped with water and sound alarm to automatically cut off heating source or function.
4.temperature control system:
Adopting the SCR temperature control, equipped with PID function instrument, digital display table, with functions of overtemperature sound and light alarm, automatic control, also can choose PLC touch screen and preserve the historical data, to facilitate analysis of sintering process.
5. inflatable system:
Consists of all kinds of pipes and valves, and is equipped with electromagnetic relief valve, pressure sensor, when the pressure in the furnace is higher than that of TVC automatically put gas, gas pipeline is equipped with needle valve, can control your.
