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 running, it needs lubricating oil to lubricate it. The Zhejiang fan, otherwise, cannot operate normally. Two to three drops of lubricating oil need to be dripped per second to ensure the lubrication of the fan impeller so that it can operate 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. Hunan fans, most of the air that is conveyed, the fans contain some oil.
Rotary blowers are mainly used in some small sewage treatment. The advantages are low noise, low energy consumption, and relatively cheap.
The performance parameters of the fan mainly include flow, pressure, power, efficiency and speed. In addition, the magnitude of noise and vibration is also the main fan design index. Flow is also called air volume. Jiangsu fan is expressed by the volume of gas flowing through the fan per unit time. Pressure is also called wind pressure, which refers to the increase in the pressure of the gas in the fan. There are static pressure, dynamic pressure and full pressure. Power It refers to the input power of the fan, that is, the shaft power. The ratio of effective fan power to shaft power is called efficiency. The full pressure efficiency of the fan can reach 90%.
Fans are widely used in ventilation, dust extraction and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances Drying and sending of grain; wind tunnel wind source and hovercraft inflation and propulsion. The working principle of the fan is basically the same as that of the turbine 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.
Technical requirements for fire exhaust fan
Product performance requirements,
1. The motor adopts high-quality motor.
2. The fire exhaust fan should be able to run normally for a long time under the condition that the medium temperature is not higher than 85 ℃.
3. The fire exhaust fan should ensure that it can work continuously for 30min when the temperature of the conveying medium is 280 ℃, and it can continue to operate normally when the temperature of the medium is cooled to the ambient temperature
4. At the rated speed, in the working area, the measured pressure curve of the fan and the curve given in the manual should meet the following requirements:
a) At the specified flow rate, the axial pressure fire smoke exhaust fan has a deviation of ± 5%.
b) At the specified flow rate, the corresponding pressure difference of the centrifugal smoke exhaust fan is ± 5%.
5. The noise limit of sound level A of fire exhaust ventilator at the given operating point in the description shall comply with the provisions of JB / T8690.
