In the specific aspects of negative pressure fan, cooling on this aspect can be said to be very important, but also must understand the master, otherwise our learning is incomplete. Therefore, since it has a certain importance, Hongfeng negative pressure fan to analyze, in order to grasp in time, and make reasonable use.

1., the negative pressure fan cooling on this aspect of the note

In the negative pressure fan cooling on this aspect, for all of us, especially learners, should know and master, mainly have:

(1) the valve in the suction fan, and some other valves to open and close action to check whether the flexible and reliable, and signs are visible, so as to avoid the problem of adverse effects.

(2) for each component of negative pressure fan, should conduct a comprehensive inspection, there cannot be any omission, is mainly to see whether the abnormal or problems, and fan voltage and current, is in the normal range, the fluctuation is normal. Because, if these problems, then it will affect the negative pressure fan cooling effect.

(3) installed on the suction fan, to be correct and in place, can not have a tiny bit error, so that the cooling effect is affected by.

2. in negative pressure fan cooling, what are the related factors?

In the negative pressure fan cooling on the one hand, the related factors, the working principle of the wind turbine, the speed, blade number, blade angle and chord length, if they have a good match, then can make the negative pressure fan has good cooling effect. And, if the number of leaves, leaf blade installation angle and chord section is determined, then is to determine the speed of the match.

Hoffen negative pressure fan attention is that in the design of technical parameters are given, the negative pressure fan speed should be designed for speed, this is quite good, and to avoid too large or too small, so as not to affect the negative pressure fan cooling effect, which affects the performance of the fan play.
