Vacuum Hot Press Furnace System Structure

Vacuum hot pressing furnaces are usually composed of several mechanical systems, as follows:

1. Vacuum system: It consists of oil diffusion pump, Roots pump, mechanical pump distribution electromagnetic pressure differential valve (to prevent sudden power outage, mechanical pump oil backfilling) inflatable valve, exhaust valve, vacuum butterfly valve, vacuum pressure gauge (+Pa) bellows, vacuum pipeline and support.

2. Hydraulic system: electric input mode is adopted. The hydraulic station is equipped with imported proportional valves, pressure sensors, displacement display, grating ruler (ranging accuracy 0.02 mm), hydraulic cylinder and other related hydraulic devices. The pressure regulation is semi-automatic and can be adjusted manually. The instrument can set the pressure automatically, and can realize voltage stabilization and holding.

3. Water cooling system: It is composed of various valve and pipeline related devices and has the function of automatically cutting off heating source or function of water-cut sound and light alarm.

4. Temperature control system: SCR is used to control temperature, equipped with PID function instrument and digital display meter. It has the function of over-temperature sound and light alarm. PLC touch screen can also be used to control temperature automatically, and historical data can be retained to facilitate the analysis of sintering process.

5. Inflation system: It is composed of various pipelines and valves, and equipped with electromagnetic vent valve and pressure sensor. When the pressure in the furnace is higher than the safety value, it will automatically vent. The inflatable pipeline is equipped with needle valve, which can control the inflatable volume.
