JZJQ Fully Gas-Cooled Roots Vacuum Unit JZJQ Gas-Cooled Roots Vacuum Pumping System
Usage Overview:
Due to limitations in pumping speed characteristics and structural mechanisms inherent in existing dry vacuum pumps—such as screw vacuum pumps and claw-type vacuum pumps—these models cannot meet the demands of certain applications. The JZJQ air-cooled Roots pump, however, is designed by connecting two or more Roots vacuum pumps in series. Each stage of the Roots pump can be equipped with either a motor or a heat exchanger, allowing it to start at different pressure levels. Additionally, variable-frequency control enables precise adjustment of the pumping speed, ensuring oil-free operation while delivering high pumping speeds suitable for rough vacuum conditions. This innovative solution finds extensive use across industries such as aerospace, power generation, steel processing, pharmaceuticals, and chemical engineering.
Advantages and Features:
• High speed, oil-free, and capable of high pumping rates;
• Short pumping time and high rough vacuum pumping speed;
• The unit can be started at any pressure by optionally equipping it with a motor and a heat exchanger;Indicator

Precision Machining
The forged billet is turned by a CNC lathe to remove most of the allowance, making the shape of the rotor closer to the design size, while leaving an appropriate machining allowance for the subsequent fine processing. The precision machining of the screw profile is carried out using a MAZAK precision machining center. Through precise programming and processing, the profile accuracy of the screw rotor is controlled within the design requirements.
Assembly
After the installation engineer checked the vacuum pump materials, they assembled the vacuum pump products in accordance with the drawing requirements and conducted pressure tests and usage debugging on the assembled vacuum pump products.
Quality inspection
After each processing step of the product is completed, the quality inspection team conducts quality checks based on the processing technology and product standards. Products that do not meet the standards need to be reworked or scrapped.
Shipment
After all processing procedures are successfully completed, the staff responsible for packaging and shipping will check each product against the shipping documents one by one. Once the information is accurate, they will contact the logistics to arrange for shipping.
Experience accumulation
Focused on vacuum systems for 16 years, with deep industry experience and highly specialized manufacturing expertise.
