Fan selection is a very technical task, and there are many specific selection methods, such as: selection by dimensionless characteristic curve, selection by logarithmic coordinate curve, selection by dimensional characteristic curve or performance table, Selection of variants, selection of pipe network resistance, etc. At present, Hunan fans are also selected through the Web online selection system and the use of special selection software. The methods are numerous and complex, and some methods require certain expertise.
For general business personnel, it is sufficient to be familiar with and master the two methods of dimensioning table selection and fan selection software. These two methods are simple and easy to operate. When selecting a fan, first of all, according to the basic parameters of the required air volume and full pressure of the fan, the model and number of the fan can be determined through the dimensioned performance table of the fan (each fan product manual has relevant data), and the ventilation At this time, more than one product may meet the requirements; at this time, the type, model and structural material of the fan are selected in accordance with the fan application, process requirements, and application occasions to meet the required working conditions, and strive to make the rated flow of the fan And the rated pressure, as close as possible to the flow and pressure required by the process, so that the operating condition point of the fan when it is running is close to the effective area of the fan characteristics.
What oil is used in rotary blowers? Can rotary blowers work without fuel? Please read below to learn more about rotary blowers.
When the rotary blower is running, it must not be refueled, otherwise short-term damage will occur. When the rotary blower is in operation, it needs lubricating oil to lubricate it, otherwise it cannot operate normally. When the rotary blower is in operation, it needs to drop per second. Add two to three drops of lubricating oil to ensure the lubrication of the fan impeller so that it can run normally.
The rotary blower has a separate oil and gas separation chamber. In order to save the oil recovery device, it is not possible to fully separate the oil and gas. Most of the air transported contains some oil.
Rotary blowers are mainly used in some small sewage treatment. The advantages are low noise, low energy consumption, and relatively cheap.
The role of centrifugal fans
Centrifugal fan is a machine that relies on the input of mechanical energy to increase the pressure of the gas and exhaust the gas. The Anhui fan is a driven fluid machine.
Centrifugal fans are widely used in ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced draft of boilers and industrial furnaces; cooling and cooling of air conditioning equipment and household appliances Ventilation; drying and sending of grain; wind tunnel wind source and inflation and propulsion of hovercraft.
The working principle of a centrifugal fan is basically the same as that of a turbo compressor, but because the gas flow rate is low and the pressure does not change much, it is generally not necessary to consider the change of the specific volume of the gas, that is, the gas is treated as an incompressible fluid.
Centrifugal fans can be made into right-handed and left-handed versions. When viewed from the side of the motor, the impeller rotates clockwise, called right-handed fan, and counterclockwise, called left-handed,
