[Case Study] Vacuum Exhaust System for Large Immersion Devices

Exhaust to below 10 Pa from atmospheric pressure within 7 minutes! A case where we provided our vacuum exhaust system.

We would like to introduce a case study of a "vacuum exhaust system" that uses a large Roots vacuum pump as the main pump to repeatedly evacuate the impregnation tank in a large impregnation device from atmospheric pressure to a vacuum state. In this case study, it was required to evacuate the impregnation tank with a volume of 13m³ from atmospheric pressure to below 10Pa within 7 minutes. When the set vacuum level is reached, the Roots vacuum pump is activated by a vacuum switch installed on the intake side. A relief valve that opens and closes by the weight of the valve body is provided between the intake and exhaust ports, allowing the pump to be activated from the high-pressure side. 【Features】 ■ When the set vacuum level is reached, the Roots vacuum pump is activated by a vacuum switch installed on the intake side. ■ A relief valve that opens and closes by the weight of the valve body is provided between the intake and exhaust ports, allowing the pump to be activated from the high-pressure side. ■ The motor, vacuum switch, and solenoid valve are all explosion-proof specifications. *For more details, please refer to the related links or feel free to contact us.
