Quality First! We always dedicated to strict quality control and thoughtful customer service.
The quality of the fan has always been the concern of users. How can the fan user judge the quality of the fan when selecting the fan?
In the process of selecting a fan, the first concern of the user is the quality of the fan, but in the face of a variety of fan types, how should the user judge whether the quality of the selected fan meets the regulations?
A fan with good quality can reduce a lot of unnecessary troubles in future use. Let's take a look at a few common features that are common to high-quality fans:
We all know that when choosing a fan, the most important thing is the flow rate, wind pressure, speed and efficiency of the fan.
When choosing a high-pressure fan, you must start from many aspects. Under the same conditions, for a high-pressure fan, the impeller is an important factor that reflects the processing level and quality of the high-pressure fan. After partial enlargement, it can be seen that the cutting amount of each tooth of the fan blade is obviously uneven, and the difference of the fan blade is mainly reflected in its shape and geometric size.
It means that the end face is not perpendicular to the axis, so that all the blades of the entire fan blade are not on the same vertical plane, which reduces the fan efficiency, and the airflow is unbalanced when the fan blade rotates. Therefore, fans with such problems should not be used in high-pressure fan testing. 3D laser scanning is our most widely used non-contact measurement method.
At present, although 3D laser scanning cannot reach the level of precision of CMM technology, it has a large measurement range and fast measurement speed, and can accurately measure the 3D contour data of various complex parts.
When performing error analysis on the entire fan blade, it is necessary to collect the data of the entire fan blade, which has a large amount of information, and the measurement data is large and complex.
