Fans are mechanical equipment that converts gas compression and gas transportation machinery, rotating mechanical energy into gas pressure energy and kinetic energy, and uses gas to perform directional transportation.

The use of high-pressure fans is like the key to keys and locks. Selecting the right high-pressure fan is also the selection of high-pressure fans.

Does the fan's noise appear to be a quality problem? The noise may not necessarily be a quality problem. It may also be analyzed due to the daily failure to perform maintenance. How to solve it: Improper installation of the belt cover causes vibration. At this time, check the reinstalled belt cover. OK;

Energy consumption calculation: Axial-flow fan for warehouse No. 14 has accumulated ventilation for 50 days, an average of 15 hours per day, and 750 hours of sharing. The average water content has decreased by 0.4%, and the average food temperature has decreased by 23.1 degrees. The unit energy consumption is 0.027kw.h /t.°C. The 28th warehouse has been ventilated for 6 days, sharing 126 hours, the average water content has decreased by 1.0%, the average temperature has decreased by 20.3 degrees, and the unit energy consumption is 0.038kw.h / t. ℃.

When the ventilator works in series in the pipe network, the flow in the suction duct and the exhaust duct is completely equal to the flow in the ventilator I and the ventilator II. Pipe network resistance is overcome by the sum of the pressures of the two fans. When the ratio of the resistance of the branch pipes between the fans to the resistance of the entire pipe network is very small, it can be ignored.

Vortex fans are mainly used to remove moisture and dust from blow-out parts in mechanical processing, as well as blow-off power control cabinets, electronic components, bearings, and welding parts. Provide more cleaning and drying for mechanical equipment and hardware equipment, also can cool the gas, thermocouple cold junction constant temperature, laboratory heating or cooling, biological freezing, blowout of medical and surgical accessories, etc.

Roots blowers have 4 bearings. If the bearing is damaged, the gap between the impeller and the impeller, the sleeve and the wall plate will change. Impeller friction causes the fan to rotate. This is an indirect cause of changes in impeller clearance. This is also a common reason why impellers cannot rotate.

One way to improve the wear resistance of the fan: wear resistance is related to daily use and its quality. Regarding the quality of Roots blowers, we have no problem with Roots blowers from Shandong Sanniu Machinery, so we must pay more attention in ordinary daily use, but even if we pay more attention to it, it will still wear out. No wear, but there are some ways we can improve the wear resistance of Roots fans.

The main disadvantages of single-stage centrifugal fans are: large maintenance workload and high difficulty.

What are the characteristics of the basic components of the fan: Safety valve: It is a safety device on the unit. When the system is in an abnormal state, when the negative force is higher than the rated pressure of the fan, the safety valve automatically opens, venting the gas for unloading, preventing the fan. And motor overload, the system is automatically protected.

Corrosion design of centrifugal fan: An excellent design can prolong the service life of the equipment and ensure the safety of the equipment. The same is true for centrifugal fans, so the structural design of the structure, which is easy to accelerate corrosion, is the stress concentration tendency and the gap environment. Sometimes Although the corrosion rate is small in the metal immersion solution, the gaps are formed, which will cause severe crevice corrosion due to the changes in the chemical and electrochemical states of the internal solution. A basic idea for controlling corrosion is to isolate the corrosive environment. In the design of centrifugal fans, surface treatment methods such as flange, zinc plating, chrome plating, and chemical plating are often used. These methods are effective in many environments. The base material and the plating layer are two types of materials whose linear expansion coefficients are different, which will cause a different amount of deformation during the elastic deformation of the rotating part, thereby causing a large number of micro-cracks; if the aforementioned phenomenon exists, it will accelerate the formation of corrosion .
