Side channel blower application in Aquaculture (Fish pond aeration )

The aeration high pressure blower for fish pond culture is a necessary power source equipment to meet the needs of aquaculture and improve the economic benefits of aquaculture;

The working principle

The blower in aquaculture, also known as aeration blower, is a kind of aeration equipment that releases tiny bubbles by compressed air in the aeration device arranged in aquaculture water, and then carries on mass transfer with water during the rising process of these bubbles, so that oxygen can be dissolved slowly into the water, so as to improve water quality.

At present, there are three commonly used blowers on the market: rotary blower, water ring blower, and the side channel blower;

The shell and impeller of the blower are made of die-casting aluminum alloy, which has the advantages of stable operation, safety, reliable insulation, no oil and pollution;

In our breeding process, the rational use of the aerator can not only prevent and reduce floating heads, but also improve the water quality, strengthen the water circulation of the pond, and promote plankton reproduction.

Other purposes of high-pressure aeration blower products for fish pond culture are: to send air into gas transmission pipeline, to send air into microporous aeration pipe or other aeration devices.

Because of its small pore size, it can produce a large number of micro fine bubbles from the pipe wall to disperse into the water, and the rising speed of the bubbles is slow in the water, the travel length of the bubbles in the water is long enough to contact with the water body, the gas-liquid oxygen molecular exchange is full, and the rotation and up-down flow of the water flow are increased.

And we should know that the up and down flow of water will bring the oxygen rich water in the upper layer into the bottom layer while the rotating flow of water will diffuse the oxygen rich water around the microporous tube outward to realize the even oxygen enrichment of the water in the aquaculture pool.

The commonly used model of high-pressure aeration blowers for fish pond : 1.1KW, 1.3KW, 1.5KW, 1.6kw, 2.2kW, 3KW, 3.7KW, 4kw, 5.5kW, 7.5kW, 8.5kw11kw, 12.5KW, 15kw, 25kW;

Wind pressure: 50mbar-650mbar;

Air volume: 40 m3 / h-1134 m3 / h (for the convenience of selecting different specifications, single-stage / double stage models are available);

Frequency: 50Hz / 60Hz; voltage: 110v-615v, universal voltage, all countries can use it. If special voltage is needed, it can be customized.

Fishpond oxygenation high-pressure blower configuration 1. Shell material: super strong die-casting aluminum, die-casting aluminum is the same as Benz automobile wheel, compared with ordinary aluminum alloy, die-casting aluminum is stronger, compared with iron shell blower, more lightweight.

Another is the motor performance that customers love to care about: the motor developed by our company is a broadband, wide voltage motor, listed in: single-phase 110V / 230V industrial three-phase: 220v / 380v / 415v / 660v, motor frequency can be 45hz-75hz frequency modulation, IP55 protection level F insulation level, its advantage is the technology that domestic motor can not reach, which is favored by customers at home and abroad.

4. Bearing of high-pressure blower: the core components are ors Turkish (optional), German SKF (optional), Japanese NSK (standard) brand bearing, bearing Zui can withstand 350 ° C, 4000 rpm. For ordinary performance bearings, the performance is stable, low noise, maintenance free, longer service life, can ensure the blower to run longer.

Transmission mode: coupling direct connection is the main mode. If required by performance specifications, the V-belt pulley can also be selected for speed change. Elastic coupling is selected for coupling, which can mitigate impact and compensate a small amount of axis deviation. Large flow blowers can be driven by steam turbine or other drives besides motor.

It can operate for 7 times 24 hours for a long time without shutdown, not easy to damage, and can be used at ease.
