The use of mechanical, physical, chemical, physical and chemical methods such as containers to be aspirated to obtain and maintain a 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 trococyclic vacuum pump, a dry vacuum pump , A Roots vacuum pump 9, a molecular vacuum pump 10, a traction molecular pump 11, a hybrid vacuum pump 12, a water jet vacuum pump 13, a gas jet pump 14, a steam jet pump 15, a diffusion pump, and the like include an adsorption pump and a cryopump . Currently the most widely used in industrial water ring vacuum pumps and rotary vane vacuum pumps. W-type reciprocating vacuum pump (ModelWPistonVacuumPump) is to obtain a rough vacuum one of the major vacuum equipment. 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. 2XZ rotary vane vacuum pump (Model2XZ SlidingVaneRotaryVacuumPump) has the advantages of compact structure, small size, light weight, low noise, 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. XD rotary vane vacuum pump (ModelXDSlidingVaneRotaryVacuumPump) can work at any inlet pressure, has been widely used in food vacuum packaging, plastic vacuum forming industry. Printing industry, paper transportation, vacuum fixtures, and vacuum to attract. SZ, SK series water ring vacuum pump (ModelSZWaterRingVacuumPump) is mainly used for rough vacuum. Pumping large amount of process. It is mainly used to remove air and other non-corrosive, water-insoluble gas containing a small amount of solid particles in order to create a vacuum in a closed container. Sucked in the gas mixture allows a small amount of liquid. It is widely used in machinery, pharmaceuticals, food, petrochemical and other industries. 2SK, 2SK-P1 series of two-stage water ring vacuum pump (Model2SK, 2SK-P1WaterRingVacuumPump) is mainly used to remove air and other corrosive, insoluble in water, allowing a small amount of gas containing solid particles. Widely used in food, textile, pharmaceutical, chemical and other industries in the vacuum evaporation, concentration, impregnation, drying and other processes. The pump has a high degree of vacuum, simple structure, easy to use, reliable, easy maintenance features. JZJS Roots - Water Ring Pump Unit (ModelJZJSRoots - WaterRingVacuumPumpSystem) This unit is due to the use of water ring pump as the foreline pump, which is particularly suitable for the removal of a large amount of water vapor and with a certain corrosive and condensable gas process Process. Such as: vacuum distillation, evaporation, dehydration, crystallization, drying and other processes. Model JZJX Roots-Sliding Vane Rotary Vacuum Pump System (JZJX) is based on the Roots pump and the rotary vane pump is connected in series. Its compact structure, easy to operate. For pumping air and other non-condensable and non-corrosive gases, are widely used in a variety of real systems that require large pumping speed and high vacuum. Such as: vacuum smelting, power capacitors, transformers, vacuum impregnation, vacuum coating equipment in the pre-pumping and so on. ZJ series Roots vacuum pump (ModelZJRootsVacuumPump) is a rotary varactor vacuum pump must have a foreline pump can be used in a wide range of pressure has a larger pumping speed of the gas is extracted gas contains dust and water vapor Sensitive widely used in metallurgy, chemicals, food, electronic coating and other industries. HIB - SZ series of chemical corrosion-resistant ceramic water ring vacuum pump People often encountered in the use of transport of chemical gases, which requires the introduction of corrosion-resistant vacuum pump new concept. It is the use of ceramic special medium to do the flow of the part, in line with the usual "wear-resistant, acid, alkali, high temperature" requirements. This model is Shanghai Yihai recently introduced new products. 2BA series of direct-connected water ring vacuum pump 2BA-type water ring vacuum pump is my factory to meet the vacuum pump can be inhaled water requirements, the original SKF-type and 2FA water ring vacuum pump based on the self-developed from the new A generation of water ring vacuum pump. Its advanced design, novel structure, suitable for a variety of more demanding, complex applications. It can suck a medium containing a large amount of water vapor and condensable gas, which is not dangerous when pumping inflammable, explosive or poisonous, corrosive gas, so it can be widely used in machinery, petroleum, chemical, electric power, pharmaceutical, 2BA type water ring vacuum pump respectively replace SZ, SK, 2SK-3,2SK-6,2S-185, respectively, for the food, ceramics, sugar, printing and dyeing, metallurgy, plastic, tile, leather and other industries , 2SK-230 and W-type reciprocating vacuum pump.
