Will the air volume of three leaf Roots blower decrease after being used for a long time?

Today, a netizen in the group asked Xinqian Shun Fan, will the air volume of the three leaf roots fan change after long use? Is the air volume increasing or decreasing? Does it have any impact? Xinqian Shun Fan Editor told us that after using Roots Fan for a long time, the air volume will decrease, and the air volume of Roots Fan with poor quality will decrease at a higher rate. Why is this so? Let's talk about Xinqian Shun Fan

1. Wear of accessories of three leaf roots blower

The closed cavity of the three leaf roots blower is composed of the impeller, the casing and the wallboard. The three leaf roots blower is designed with a certain standard clearance. As long as the clearance is larger, the air volume of the roots blower will be smaller, whether between the impeller, between the impeller and the wallboard, or between the impeller and the casing, As long as the gap changes, the air volume will decrease, and the friction between parts will affect the obvious change of the gap.

On the other hand, the three blade roots blower delivers clean air, but in normal use, the cleanliness of the three blade roots blower cannot be fully guaranteed, and some dust particles are often mixed in. After these particles are inhaled, they tend to get stuck between the impeller and cause more serious wear.

2. The increase of internal leakage is the reason for the decrease of air volume

First, let's look at the dynamic diagram of the three leaf roots blower (click the link to go directly to it). It can be seen from the dynamic diagram that when the impeller of the three leaf roots blower rotates, the gas will be transported away. There are certain gaps between the impeller and the impeller, between the impeller and the wallboard, and between the impeller and the casing. When the transportation is removed, because of the pipe pressure in front, The gas will return to a part, which is called the internal leakage part.

If the internal leakage increases, the air volume of roots blower will decrease, resulting in insufficient air volume.

3. So how to slow down the air volume?

After a long time of use, it is difficult to ensure that the air volume is the same as the air volume when leaving the factory. This is also the use loss of Roots blower. If you ask me, is there any way to slow down the air volume? In fact, there are some methods, such as:

When purchasing, we should purchase high-quality Roots blowers. The quality here is not only the material quality of the product, but also the design should be standard, and there should be no big errors. This is what we need to do from the beginning of purchasing.

What can we do after purchasing? First of all, ensure the cleanness of the surrounding environment of Roots blower, and try to reduce the entry of dust from Roots blower; Secondly, timely check the filter device of Roots blower to ensure the effectiveness of the filter device; Finally, it is also necessary to carry out regular inspection on Roots blower and do a good job in maintenance of Roots blower. Many details, if done well, can also slow down the air volume.

Summary: Whether it is a three blade Roots blower or a two blade Roots blower, the air volume will decrease after a long time of use, which is a normal phenomenon. If you have problems with the purchase of Roots blowers, you can contact our official customer service hotline.
