- Product Description
-
- Commodity name: 2BW3(4) Liquid Ring Vacuum Unit 2BW3(4) Liquid Ring Vacuum Pumping System
- 副标题: Using the customer's medium instead of water as the working fluid, it’s energy-efficient and environmentally friendly; widely applicable for compressing and transporting even toxic gases; • Operates in a closed-loop system with internal circulation, ensuring safety and high efficiency.
Structure: The unit features a liquid-ring vacuum pump as its main pump, complemented by components such as a separator and a heat exchanger. The working fluid in the closed-loop vacuum system is recycled internally, significantly reducing waste liquid discharge and offering clear environmental benefits.
2BW3(4) Liquid Ring Vacuum Unit 2BW3(4) Liquid Ring Vacuum Pumping System
Usage Overview:
When operating, this unit uses the customer's medium as the working fluid, circulating it between the separator, heat exchanger, and liquid-ring pump. This prevents mixing of the medium with the working fluid, making the process more environmentally friendly and energy-efficient. It is widely applicable to applications such as exhaust gas/torch gas recovery, VCM recovery in PVC plants, polyvinyl acetate production, liquid chlorine manufacturing, pressure swing adsorption (PSA), vacuum crystallization, filtration, and top-vacuum systems in crude oil vacuum distillation towers. Additionally, it’s ideal for compressing flammable and explosive gases like acetylene and hydrogen, as well as handling toxic and corrosive gases such as chlorine, and for vacuum conveying various materials.
Advantages and Features:
• Instead of using water as the working fluid, it utilizes the customer’s medium, making it energy-efficient and environmentally friendly;
• Widely applicable for the compressed transportation of toxic gases;
• Closed-loop operation with internal circulation—safe and highly efficient;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.
