Miniature vacuum pump principle
Miniature vacuum pumps operate on a simple principle: one nozzle is used for suction, while another serves as the exhaust. This creates a vacuum or negative pressure at the intake, and a slight positive pressure at the exhaust. The working medium is typically gas, making it a compact and efficient device.
For example, consider a sealed container initially at atmospheric pressure (100 kPa). When a miniature vacuum pump like the VAA6005 is used to continuously evacuate the container, the internal pressure can be reduced to below atmospheric, reaching an absolute pressure of 60 kPa. This makes it ideal for applications requiring controlled pressure environments.
Beyond basic suction, advanced designs allow these pumps to function as both vacuum and pressure pumps. For instance, models such as the PCF and FAA series can generate significant positive pressure at the exhaust, enabling tasks like pressurization, inflation, and overcoming system resistance. Additionally, the PHW series offers dual functionality, allowing for long-term idling and dry operation—unlike conventional pumps that may suffer damage under similar conditions.
What sets miniature vacuum pumps apart is their ability to create a pressure difference between the exhaust port and the surrounding atmosphere. Unlike larger vacuum pumps that often require oil or vacuum pump oil, they do not contaminate the working medium. They are also compact, quiet, maintenance-free, and capable of running continuously for 24 hours. These features make them highly versatile.
Due to their reliability and efficiency, miniature vacuum pumps are widely used in various fields, including medical devices, healthcare, scientific research, environmental monitoring, and more. Common applications include gas sampling, gas circulation, vacuum adsorption, accelerated filtration, and automotive vacuum boosters. Their adaptability and performance have made them essential tools in modern technology.
Magnesium Sulfonate is one of the series of lubricant additives. It`s mainly made from long-chain linear alkylbenzene sulfonic acid by means of neutralization and high alkalization reaction. As a major metal detergent, this product boasts excellent acid neutralization capacity, good antirust property and high temperature detergency, so widely used for different ICE oil.
It has the products of Overbased Synthetic Magnesium Sulfonate T107M (400TBN) and Super Overbased Magnesium Sulfonate Vanadium Inhibitor T107MV (600TBN).
