The Xin'anjiang brand JZJSV(B) series Roots screw vacuum unit features ultra-high vacuum, fast pumping speed, long service life, good safety, and high efficiency and energy saving. The Roots vacuum pump's flow-through components are made of Hastelloy alloy, and the backing screw vacuum pump is made of cast iron, enabling it to achieve ultra-high vacuum below 0.1 Pa with minimal drop in pumping speed under high vacuum conditions.
The Xin'anjiang brand series of Roots screw vacuum units are vacuum equipment that uses a Roots vacuum pump (also known as a mechanical booster pump) as the main pump and a screw pump as the backing pump. The operation of the Roots screw vacuum unit is automatically controlled by components such as a PLC, touch screen, vacuum gauge, pressure transmitter, and electrical contact pressure gauge. The PLC system's automatic control enables automatic operation of each purging system of the screw pump, automatic start-up and shutdown of the Roots vacuum pump, and automatic monitoring and protection of the unit's current and temperature, ensuring the safe and reliable automatic operation of the entire unit.
The Roots screw vacuum unit features ultra-high vacuum, fast pumping speed, long service life, good safety, and high efficiency and energy saving.
