Jet pump is widely used in escort, compaction of mixed gas and steam, liquid and solid equipment, gas or liquid is often used as power medium. Jet pump is another very important application for generating vacuum.
The main principle of jet pump is that the liquid, gas or solid around is driven and accelerated by the liquid or gas ejected from the power nozzle at high speed. This movement leads to a mix of drive and carry-on. The velocity of injection decreases at the diffuse point while the pressure increases. Unlike traditional pumps, jet pumps have no moving parts in operation.
Jet pumps can be made from a variety of materials, such as cast iron, steel, stainless steel, Hastelloy, titanium, enamel, glass, plastics and graphite, and can be made into various sizes. When the suction volume is from 1 to 2000 000 m3/h and the suction pressure is 10-2 mbar, the size can be from several centimeters to more than 30 meters.
Due to the diversity of jet pump, it has been widely used in various fields, such as chemical reactor, exhaust system, water treatment equipment, mixing tank, storage tank, waste water treatment equipment, heating system, heating gas supply system, power plant, swimming pool, salmon factory water supply and so on. And the composition of vacuum in different industrial categories.
It is an important application field that water vapor is used as a power medium to form a vacuum for jet pumps. Its guaranteed high-speed injection is several times the speed of sound, so the jet pump can easily dispose of large-capacity materials in vacuum.
