Single-Stage Oil-Lubricated Rotary Vane Vacuum Pump System
A vacuum system consists primarily of 1 or more vacuum pumps, 1 or more vacuum receiver tanks and a central power-control cabinet, with vacuum controls, solenoid valves and other components configurable to customer requirements. Pumping speed, capacity and vacuum pressure can be selected and adjusted for different processes to supply a whole factory or multiple machines. Advantages: 1. Low noise/vibration reduces plant noise; 2. Central installation saves space and simplifies maintenance; 3. Centralized supply provides more available capacity than the same number of separately installed pumps under equivalent conditions; 4. Automatic pump switching according to demand saves electricity; 5. Receiver tanks buffer flow and facilitate some drainage or light filtration, reducing contact between moisture/other process media and pump oil. The single-stage rotary-vane system is ideal for obtaining high vacuum while removing air, inert gases and small quantities of condensable vapor. It comprises pumps, PLC control, receiver tanks, piping, valves and an overseas filtration assembly. Oil-lubricated single-stage rotary-vane operation: A motor-coupled rotor turns eccentrically in a cylindrical housing, making line contact with its wall. Sliding vanes divide the space into chambers. Chambers draw gas through the inlet, compress it during rotation and discharge it to the oil/gas separator. A constant pressure difference draws lubricating oil into the compression chamber. Oil and gas enter the separator; gravity, oil/gas mesh and exhaust filters separate them. Oil returns to the tank bottom for recirculation, while oil-free gas vents to atmosphere. Dongguan Dalutong pump advantages: 1. Easy installation/maintenance; 2. Large oil sight glass for checking contamination; 3. Direct drive without belt/gear slack or wear; 4. High pumping speed, stable vacuum, low noise/vibration; 5. Effective air cooling and bolt-mounted pump; 6. Built-in mist separator prevents process contamination and keeps the environment clean; 7. Gas ballast handles some water vapor/condensable gas for long life; 8. Inlet check valve prevents oil/gas backflow when stopped. Uses include vacuum coating, microelectronics, optoelectronic semiconductors, solar energy, smelting, packaging/testing, vacuum impregnation and plasma cleaning. As a pump manufacturer, Dalutong supplies various vacuum systems; experienced engineers provide comprehensive solutions and equipment support to reduce procurement costs.

Against the evolving demands for military‑grade hardware, rail transit equipment and heavy‑duty machinery that run under high‑shock vibrating conditions, anti‑loose connectors serve as indispensable hardware for stable power delivery and high‑speed signal transmission.
For low-frequency RF, electromagnetic testing and power combining systems, conventional resistive power dividers bring high insertion loss, while standard directional couplers cannot provide equal-amplitude signals with 180° phase shift. They fail differential circuits, balanced amplifiers and signal cancellation systems.
For pulsed laser and full-spectrum optical testing, photodiodes and thermopiles have inherent drawbacks. Photodiodes show weak response in infrared band, while thermopiles feature slow response and cannot capture nanosecond narrow pulses.
