Liyang PAVSD+ series vacuum pump is an energy-saving and environmentally friendly permanent magnet frequency conversion micro-oil screw vacuum pump. The "engine" of any central vacuum system is the vacuum pump. In order to cope with the changing vacuum demand in the production process, the vacuum pump often starts and stops frequently. , which not only increases the probability of failure, but also causes energy waste. To this end, Liyang has launched permanent magnet variable frequency drive (VSD+) technology, which uses the inlet pressure sensor feedback to prompt the computer controller to analyze the pressure fluctuation trend and other operating conditions, and provide The frequency converter provides speed regulation instructions, and the frequency converter responds quickly and accurately maintains the inlet vacuum pressure, so that the pumping speed and energy consumption of the vacuum pump meet user needs.
Aeries Features
High Energy Efficiency
Thanks to variable frequency drive control, PAVSD+ delivers the required flow rate without excess and wasted energy.
High Reliability
Advanced air flow guidance technology ensures instant cooling of electronic components, thereby extending their service life; the internal metal tube oil and gas circuit design allows the lubrication and cooling oil circuit to run faster, taking away the heat of the host in a more timely manner, ensuring that the air end is at the optimal temperature Run under.
Sustained Productivity
Using high-speed cyclone separation technology to efficiently separate oil and gas; multi-channel pressure detection, stronger protection function; automatic water filtration treatment effectively handles condensation water under vacuum conditions.
Easy And Quick Installation
The product adopts a plug-and-play vacuum solution, including the controller, electrical room, vacuum body and external sheet metal, which can be installed quickly.
