The use of mechanical, physical, chemical, physical and chemical methods to extract the container to obtain and maintain the vacuum device. Vacuum pumps and other equipment (such as vacuum vessels, vacuum valves, vacuum gauges, connecting lines, etc.) constitute a vacuum system and are widely used in electronics, metallurgy, chemical, food, machinery, medicine, aerospace and other sectors.
According to its working principle, basically divided into two types of gas delivery pump and gas capture pump.
Gas transfer pumps include: 1, liquid ring vacuum pump (water ring vacuum pump) 2, reciprocating vacuum pump 3, rotary vane vacuum pump 4, fixed-plate vacuum pump 5, spool valve vacuum pump 6, trochoidal vacuum pump 7, dry vacuum pump 8 Roots vacuum pump 9, molecular vacuum pump 10, traction molecular pump 11, compound vacuum pump 12, water jet vacuum pump 13, gas jet pump 14, steam jet pump 15, diffusion pump and other gas trapping pumps include: adsorption pump, cryogenic pump, etc. .
The most widely used in the industry today are water ring vacuum pumps and rotary vane vacuum pumps.
W-type reciprocating vacuum pump (ModelWPistonVacuumPump)
It is one of the major vacuum equipments for obtaining rough vacuum. Widely used in chemical, food, building materials and other departments, especially in vacuum crystallization, drying, filtration, evaporation and other processes are more appropriate.
2X Rotary Vacuum Pump (Model2XSlidingVaneRotaryVacuumPump)
One of the basic equipment used to extract gas from a closed container. It can be used alone or as a foreline pump for booster pumps, diffusion pumps, and molecular pumps. The pump is widely used in metallurgy, machinery, electronics, chemical, petroleum, pharmaceutical and other industries in vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying and other processes.
2XZ Rotary Vacuum Pump (Model2XZSlidingVaneRotaryVacuumPump)
It has the advantages of compact structure, small size, light weight, low noise, and low vibration. Therefore, it is suitable for use as a fore pump of a diffusion pump, and is more suitable for precision instrument matching and laboratory use. For example: mass spectrometry instruments, refrigerator lines, vacuum freeze dryers, etc.
XD Rotary Vacuum Pump (ModelXDSlidingVaneRotaryVacuumPump)
It can work under any inlet pressure and has been widely used in vacuum packaging of foods and vacuum plastic molding of plastics industry. Printing industry, paper transport, vacuum fixtures, and vacuum suction.
Related vacuum pump product series: 2X rotary vane vacuum pump, 2XZ rotary vane vacuum pump, XD rotary vane vacuum pump, W-type reciprocating vacuum pump, 2SK two-stage water ring vacuum pump, and SK type direct-connected water ring vacuum pump.
Fused Silica features high transmission from 200nm to 2.2μm with a low coefficient of thermal expansion, making it ideal for the most demanding ball lens applications in the ultraviolet, visible, and near infrared spectra. Ball lenses are commonly used for improving signal coupling between fibers, emitters, and detectors, as well as objective lenses in endoscopy and bar-code scanning applications. Half-ball lenses simplify handling and integration.Half ball (hemispherical) lenses are ideal for applications such as fiber communication,endoscopy,microscopy,optical pick-up devices and laser interferometry and measurement.
