Vacuum pump It can be used alone, can also be used as a booster pump, diffusion pump, molecular pump foreline pump to maintain the pump, titanium pump pre-pumping. Can be used for electric vacuum container manufacturing, vacuum welding, printing, plastic, refrigeration equipment maintenance and instrumentation equipment and laboratories. Widely used in food, scientific research, medical, electronics, chemical, pharmaceutical, tertiary institutions and other departments. Vacuum pump Vacuum pump using mechanical, physical, chemical, physical and chemical methods such as the container to pump gas to obtain and maintain the vacuum device. Vacuum pumps and other equipment (such as vacuum vessels, vacuum valves, vacuum measuring instruments, connecting pipes, etc.) form a vacuum system and are widely used in electronics, metallurgy, chemical, food, machinery, medicine, aerospace and other departments. According to their working principle, basically divided into gas delivery pump and gas capture pump two types. The gas delivery pump includes a liquid ring vacuum pump (water ring vacuum pump), a reciprocating vacuum pump, a rotary vane vacuum pump, a fixed vane vacuum pump, a slide valve vacuum pump, a trochanter vacuum pump, a dry vacuum pump 8, the Roots vacuum pump 9, the molecular vacuum pump 10, the traction molecular pump 11, the composite vacuum pump 12, the water jet vacuum pump 13, the gas jet pump 14, steam jet pump 15, diffusion pumps and other gas capture pumps include: adsorption pump and cryogenic pump Wait. Currently the most widely used in industrial water ring vacuum pumps and rotary vane vacuum pumps. The Model W Piston Vacuum Pump is one of the major vacuum devices for obtaining rough vacuum. Widely used in chemical, food, building materials and other departments, especially in the vacuum crystallization, drying, filtration, evaporation and other processes more appropriate. Model 2X Sliding Vane Rotary Vacuum Pump One of the basic equipment used to evacuate gas from a closed container. It can be used alone, but also as a booster pump, diffusion pump, molecular pump foreline pump use. The pump is widely used in metallurgy, machinery, electronics, chemicals, petroleum, pharmaceutical and other industries vacuum smelting, vacuum coating, vacuum heat treatment, vacuum drying process. ModelXX Sliding Vane Rotary Vacuum Pump has the advantages of compact structure, small size, light weight, low noise and small vibration. Therefore, it is suitable for diffusion pumps for the foreline pump, but also more suitable for precision instrumentation and laboratory use. For example: mass spectrometry equipment, refrigerator lines, vacuum freeze-dryer and so on. Model XD Sliding Vane Rotary Vacuum Pump can be any
Hexagon slotted nut, that is, the groove is machined above the hexagon nut. It is used in conjunction with threaded Bolt with hole and cotter pin to prevent the relative rotation of bolt and nut. Hexagon slotted nut is generally used in vibration and impact situations. After the nut is fastened, it needs to be equipped with cotter pin hole and installed with cotter pin. Such as lifting equipment, artillery, press, die-casting machine, etc.
