The structural characteristics of the aquatic plant aeration and Sweetwater blower: the internal mechanism is relatively tight, and the gap between the impeller and the casing is small, so the garbage and dust are filtered. Regarding sundries, in general, fine filters and dust are installed at the air inlet, and filters are often used. It uses filter elements with different filtering precision according to different use sites. Different filter elements have different maintenance methods and service life, and should be heard frequently when ordering. In some special cases, special protection for plastic high-pressure fans is required: for example, when used in a closed environment, attention must be paid to ventilation and heat dissipation; in the case of ambient temperature (higher intake temperature), attention should be paid to ventilation and heat dissipation. Alternatively, select a high pressure blower with a high wind temperature.
1. Mechanical loss: When the Sweetwater blower is working, its bearings, impellers, etc. consume some of the useful energy due to mechanical friction, causing mechanical loss; this loss is mainly represented by power consumption, which is independent of the wind pressure and flow of the fan, and can be regarded as pure power. loss.
2. Flow loss: When gas flows in the main duct of the fan (suction chamber, vane rotation channel, vane, casing and outlet, etc.), some useful energy is consumed due to flow resistance, resulting in flow loss; these losses reduce the fan The wind pressure reduces the effective power, which can only be seen as a loss related to wind pressure.
3. Volume loss: Due to the gap between the rotating part and the static part, when the impeller rotates, a pressure difference is generated on both sides of the gap, so that the impeller leaking from the high pressure side to the low pressure side causes a volume loss of the fluid portion (only with the flow rate) Related, also known as flow loss). It leads to a reduction in the effective power, which can only be seen as a loss related to the flow.
4. Full pressure efficiency refers to the ratio of the total effective power of the Sweetwater blower to the power of the Sweetwater blower shaft. In general, it is expressed as a percentage, that is, the internal efficiency of total pressure is equal to the ratio of the total effective power to the internal power. Expressed by ηI, the static pressure efficiency refers to the ratio of the effective power of the static pressure of the fan to the axial power of the fan, that is, the internal efficiency of the static pressure is equal to the ratio of the effective power of the static pressure to the internal power, that is, without special description, The fan efficiency refers to the total pressure efficiency, that is, the ratio of the static pressure effective power to the internal power is equal to the ratio of the static pressure effective power to the internal power, that is, the Sweetwater blower efficiency is the ratio of the static pressure effective power to the fan axial power.
