(1. Shell material: The all wind high-pressure fan adopts * degree die cast aluminum, which is the same aluminum material as the wheel hub of Mercedes Benz cars. Compared with ordinary aluminum alloy, die cast aluminum is stronger and has a lighter weight effect compared to iron shell fans.).
(2) Motor performance: the high voltage fan adopts Taiwan, China all wind motor, which is a wide frequency and wide voltage motor. It is listed as follows: single-phase 110V/230V industrial three-phase: 220/380/415/660V, etc. The motor frequency can be adjusted at 45-75HZ, and IP55 protection class F insulation class. Its advantage is that domestic electric machines cannot reach the technology, which is favored by customers at home and abroad
(3. Fan oil seal: The all fan adopts German MERKEL oil seal, and the German MERKEL material is made of fluororubber, which can withstand temperatures from -25 ℃ to 300 ℃.). Compared to the general oil seal, its lip temperature is 20-50 ℃ higher than the working medium temperature during operation, making it more stable in performance, maintenance free, and has a longer lifespan.
(4. Fan bearings: The core components of the entire fan are made of German SKF and Japanese NSK brand bearings, which can withstand up to 350 degrees Celsius and 4000 revolutions per minute.). For domestically produced Luo axis and Japanese bearings, the performance is stable, the noise is low, maintenance is free, and the service life is longer, which can ensure that the fan runs longer.

fanPerformance characteristics:

1) The quality of sewage treatment fan aerators in the domestic market is diverse, with varying quality and a wide price range. Due to the lack of relevant industry standards, workshop style production methods are commonly used. If the release amount of the aerator (which is related to water depth, pressure, flow rate, and the quality of the aerator film) cannot meet the process requirements, resulting in a blower flow release rate of less than 70%, surge and increased blower pressure will occur.
2) The problem of flow velocity in the sewage treatment fan pipeline should be controlled below 16m/s. The faster the flow velocity, the greater the resistance in the pipeline network, which may cause the blower to surge and increase the blower load.
3) The hardness of the tension spring in check valves produced by different enterprises varies, resulting in different local resistance losses. If the overall pipeline resistance loss is greater than the outlet pressure of the blower, surge will also occur. When the blower is stopped, the inlet butterfly valve should be closed first, and then the outlet butterfly valve should be closed. This can avoid water backflow problems and does not require the installation of an outlet check valve. Adding check valves will increase resistance losses, equipment costs, and operating expenses.
4) According to industry standards, the design temperature of the aeration blower is 20 ℃, and for every 1 ℃ increase, the outlet pressure will decrease by about 20mmH2O. For example, when the summer temperature is 38 ℃, the outlet pressure will decrease by 360mmH2O. Fengyuan Machinery Company has raised the design temperature of the blower inlet to 37 ℃ based on the climate characteristics of high temperatures in most regions of China during summer. This means that under coaxial power, the outlet pressure is 340mmH2O higher than the national standard. According to the specific situation of the usage site, when selecting the blower, the influence of temperature changes on the outlet pressure of the blower should also be considered. When the maximum temperature Tmax of the fan is greater than 37 ℃, compensate for the inlet pressure at 20mmH2O/1 ℃.

5) Regardless of the type of aeration blower, its efficiency is relative and cannot always be maintained in actual operation. Any increase in resistance (such as valve, pipe bend, aerator resistance) will reduce efficiency. So maintaining high efficiency operation of the blower is closely related to the design of the process flow.
6) The problem of grid connection of aeration sewage treatment blower. When two or more blowers are connected to the grid, the increased resistance caused by grid connection must be considered. In the past, some users used a single blower to operate normally, but when two or more blowers were connected to the grid, there was insufficient air flow and motor current, which was related to factors such as overall gas supply capacity, aerator layout, synchronized release capacity, and reasonable gas pipeline configuration.
7) The use of vent valves for aeration sewage treatment fans. Multiple fans are connected in parallel, and only one vent valve needs to be installed. When starting the blower, if the aeration head is not yet connected, the vent valve can be opened to release some of the gas, allowing the blower to reach a certain flow rate. After the pressure is stabilized, the vent valve can be closed. This can solve the problem of pressure surge caused by low flow.

Maintenance and upkeep of aeration vortex air pump:

(1) The motor of the high-pressure aeration blower is directly connected to the impeller and operates at high speed. The bearings need to be regularly maintained with grease to prevent damage (including the bearings of the impeller).
(2) The shaft power and pressure of the motor are directly proportional. To prevent the long-term extreme pressure of the high-pressure blower for sewage tank aeration from increasing the shaft power and motor load, a pressure relief valve is often used. It is an unloading valve. When the operating pressure of the high-pressure blower for sewage tank aeration exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure and protect the motor of the high-pressure blower for sewage tank aeration.
(3) The internal mechanism of the high-pressure aeration blower is relatively tight, with a small gap between the impeller and the casing, so it is necessary to filter out debris and dust. For miscellaneous items, a fine filter screen is usually installed at the air inlet. For dust, a filter is often used. It often uses filter cartridges with different filtration accuracies according to different usage scenarios. Different filter cartridges have different maintenance methods and service lives, which need to be clarified when ordering.
(4) In some special occasions, special protection is needed for the high-pressure blower of the sewage tank aeration: for example, when used in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose a sewage tank aeration high-pressure blower that allows for higher intake temperature.
