An ejector, also known as an ejector, jet vacuum pump, etc., is a vacuum-obtaining device that uses a fluid to transfer energy and mass. Its working principle is mainly based on the high-speed jet generated by the pressure fluid through the nozzle injection to drive and mix the surrounding fluid, and then realize the functions of suction, mixing, and transportation.
Inside the injector, a high-pressure working fluid, such as water or gas, is ejected at extremely high velocities through a specific nozzle structure. This high-velocity jet creates an area of low pressure at the outlet of the nozzle, which creates a suction effect. The pumped fluid, such as a gas or liquid, is introduced into the suction chamber of the ejector, where it is mixed with a high-velocity jet.
During the mixing process, the kinetic energy of the high-velocity jet is transferred to the pumped fluid, causing it to accelerate and mix with the jet. At the same time, as the speed of the mixed fluid decreases, its pressure increases accordingly, enabling fluid transfer. Eventually, the mixed fluid is discharged from the ejector through the diffusion section and discharge port.
The application field of the ejector is very wide, including material absorption and transportation, condensation, distillation and evaporation, concentration, decolorization and deodorization, oxygen supply and deoxygenation, drying and crystallization filtration, chemical absorption, tail (waste) gas neutralization and other processes. It is widely used in light industry, chemical industry, pharmaceutical, vacuum smelting, sugar making, salt making, monosodium glutamate, chemical fiber, papermaking, food, plastic rubber, ceramics, vacuum stations for large and medium-sized hospitals and factories and mining enterprises, vacuum brick making, building foundation pit dewatering, drainage, petroleum, environmental protection and other industries.
In addition, the efficiency of an ejector depends on a number of factors, including pressure, nozzle design, fluid properties, and operating conditions. Therefore, in practical applications, it is necessary to select and adjust according to specific needs and conditions in order to achieve the best working results.
In general, the injector realizes the transportation and treatment of fluids through the suction and mixing effect generated by high-pressure fluid jetting, and has the advantages of simple structure, convenient operation and wide range of application.
In which areas are injectors most widely used?
Injectors are used in a wide range of applications, but here are some of the main ones:
Industrial field
In the painting industry, automobile manufacturing, electronic manufacturing, precision machinery and other industrial fields, the injector plays an important role. It can be used for absorption and transportation, condensation, distillation, evaporation, concentration, decolorization and deodorization, oxygen supply and deoxygenation, drying and crystallization filtration, chemical absorption and other processes.
Environmental protection field
high-efficiency injectors have important applications in the field of environmental protection, which can be used for air purification, exhaust gas treatment and water pollution prevention and control, and contribute to environmental protection.
Agriculture
The ejector can be used for spray fertilization, insect control, sterilization and other operations of plants, as well as play an important role in agricultural irrigation to improve water efficiency.
Medical field
The ejector can be used to spray drugs in the mouth, nose, lungs, etc., and can be evenly sprayed on the wound through the injector. In addition, laser jets can be used to remove moles, spots, etc. from the skin.
Fire extinguisher:
Fire sprinklers can play a vital role in spraying water onto the fire source and quickly reducing the fire.
In addition, the injector is also used in seawater desalination, petrochemical industry, waste gas waste heat utilization, jet refrigeration, aerospace and other fields.
In general, due to its unique performance and working principle, the injector has important applications in various fields, which greatly improves production efficiency and environmental benefits. However, different application areas may require different types of injectors, so when selecting and using an injector, it needs to be selected and adjusted according to specific needs and conditions.
