- Product Description
-
- Commodity name: JZJY Type Tri-Lobe Roots-Liquid Ring Vacuum Pumping System
- 副标题: It can operate across a pressure range from atmospheric to several thousand Pascals; and is suitable for applications involving the extraction of gases rich in condensable vapors as well as corrosive gases.
Structure: A complete vacuum unit featuring a ZJ-type Roots vacuum pump as the main pump, paired with a liquid-ring vacuum pump as the forepump. This system can automatically control the start and stop of both the Roots and liquid-ring pumps, as well as provide automatic overload and overheat protection, all managed via an electrically connected vacuum gauge (vacuum relay) and an integrated electrical control system. Additionally, the system enables precise control over various instruments and valves.
JZJQ Fully Air-Cooled Roots Vacuum Unit – JZJY Type Tri-lobed Roots/Liquid Ring Vacuum Pumping System
Usage Overview:
The JZJY-type Roots-liquid ring vacuum unit is composed of one or more Roots vacuum pumps connected in series with a single liquid ring vacuum pump. This unit can operate continuously over a wide pressure range—from atmospheric to several thousand Pascals—and is particularly well-suited for extracting gases with high humidity, those containing significant amounts of water vapor, as well as corrosive and condensable gases. As a result, the Roots-liquid ring vacuum unit is ideal for applications such as vacuum distillation and dehydration crystallization in the chemical industry; drying polyester chips in the light textile industry; drying leather products; freeze-drying in the food industry; and vacuum impregnation and vacuum drying processes used in key components of the power industry.
Advantages and Features:
• Can operate across a pressure range from atmospheric up to several thousand pascals;
• Suitable for extracting gases that are rich in condensable and corrosive components;
• The working fluid in the vacuum unit is circulated internally, resulting in minimal waste liquid discharge and contributing to environmental protection and energy efficiency.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.
