21 years of production experience roots blower sewage treatment equipment

  21 years of production experience roots blower sewage treatment equipment , Since its formal establishment in 2000, Shandong ruituo blower Co
, Ltd
has worked hard for 19 years, worked diligently and divided the cost
In line with the principle of serving the broad masses of the people, we have actually produced Gao quality fans
With 19 years of production and processing experience + Japanese processing center + famous enterprise cooperation Case + Deguo Aizhen technology, we look coldly at thousands of fingers and bow our heads for children, We dare to be the first
We are determined to make a modest contribution to the environmental protection cause of China Guo and contribute to the banner made by China Guo all over the world In the three blade arc blade blower, for the gradually expanding gap structure, the included angle of blade profile is 120 & deg;, When the enclosure angle is 180 DEG; When, take 0 = 60 & deg;, For the large value of the theoretical gradually expanding gap structure angle, it can not only ensure that the impeller does not leak in the process of transmitting gas, but also make the change of casing structure gentle

  In the pre inlet structure with gradually expanding gap, the gap between the impeller and the inlet side of the casing is set as the fixed value, which is represented by s; The gap between the impeller and the outlet side of the casing is a gradually expanding gap, which is a function of less opening angle, expressed by B (0), as shown in Figure 3
It is assumed that the gas with unit volume V is under the action of inlet pressure P before the gradually expanding gap is opened; When the opening angle is less than 0, due to the entry of high pressure at the outlet, the internal pressure of the unit volume increases from P to P, and gas leaks to the inlet through the gap s; When 0 = 0, the pressure P is just in equilibrium with the outlet pressure PD

  Comparison of the change rate of the opening gap
With the opening of the opening gap, the high-pressure gas at the air outlet equalizes the low-pressure gas in the unit volume
Comparison of the change rate of the opening gap between the ordinary rectangular air outlet structure and the gradually expanding gap structure , The change rate of the rectangular air outlet primitive volume air outlet gap can be obtained from the curve in Figure 4
When the opening angle of the ordinary rectangular air outlet gap gradually increases, the change rate curve of the air outlet gap is steep, which shows that the change rate of the ordinary rectangular air outlet gap with less change of the opening angle is relatively large
When the ordinary rectangular air outlet gap is opened, the high-pressure gas at the air outlet will violently impact the low-pressure area in the impeller volume area due to the sudden enlargement of the air outlet gap, resulting in great backflow impact, resulting in great airflow noise

  It can be seen from the comparison of the above figure that when the pressure rise of the blower AP = 68
6kpa, the opening change degree of the opening gap of the unit volume is much more gentle than that of the opening gap of the unit volume under the rectangular air outlet structure when the casing structure adopts the gradually expanding gap structure and all working pressure rises
Therefore, under the gradually expanding gap structure, it should be able to effectively reduce the aerodynamic noise generated when the primitive volume is turned on

  Roots blower produced by Shandong ruituo has the advantages of excellent performance, low noise, strong adaptability, small floor area, sufficient power and convenient maintenance
