Q:How to judge the fan left and right rotation?
The main structural components of the fan are impeller, housing, air inlet, bracket, motor, pulley, coupling, silencer, transmission (bearing) and so on.
Q:How to distinguish between the fan coil around?
So that the air through the cold water (hot water) coil is cooled (heated) to keep the room temperature constant. Usually, the fresh air through the new air unit after treatment into the room to meet the air conditioning room fresh air volume needs.
Q:What is the use of two-speed fan?
Under normal circumstances, the fan running at low speed as exhaust ventilation, when a fire occurs, the fan immediately become high-speed operation, as a fire exhaust fan use. This machine with two, not only reduce the construction cost, save space, more importantly, greatly improve the efficiency of the use of equipment and reliability
Q:High altitude on the blower flow, pressure impact?
The air volume according to the design requirements of the wind pressure according to the design value and then by the density ratio of the standard value of the pressure value of the selected example of the design value of working conditions 80 degrees C air volume 10000m3 / h wind pressure 2000pa 80 degrees C ...
Q:How does the material of the high temperature fan choose?
The main performance indicators of the substitute materials should meet the main mechanical performance requirements of parts, B-level corrosion of the following materials shall not be applied to the rotating parts, nor shall the application of the rest of the parts on the outer surface
Q:What is the role of axial fans and centrifugal fans in mechanical ventilation?
1 due to the difference between temperature and food temperature, the first ventilation time to be selected in the day to reduce the grain temperature and temperature gap, reduce the occurrence of condensation. After the ventilation as far as possible in the evening, because the ventilation is mainly cooling, the evening the atmosphere is relatively high humidity, low temperature, which reduces the water loss, and make full use of the low temperature at night to improve the cooling effect The
Q:Why does the fan start the current?
The fan is an inductive load, which can be considered a short circuit at power-up. So the starting current is very large.
Q:What is the difference between an axial fan and a centrifugal fan?
Centrifugal roof fans change the flow of media within the duct, while the axial flow of the roof fan does not change the flow of media medium;
Q:What are the ventilation ducts for wind turbines?
8.5.8 When the electric heater is installed in the duct, the fan shall be interlocked with the electric heater. Electric heater before and after the 800mm within the duct and through the fire and other places with easy fire parts of the pipeline, must use non-combustible insulation materials
Q:What is the role of the blower in the sewage treatment plant?
In the operation of the pressure difference using the blower automatically lubricated to the drip nozzle, drip into the cylinder to reduce friction and noise, while keeping the cylinder gas does not return, such a blower, also known as the vane blower.
