Roots BlowerIn the process of practice will certainly produce conclusions, about the use of Roots blower conclusions I take you to understand.
(1) For blowers and compressors, the outlet throttling method consumes the most power. Although the relative flow Qr (actual flow Q and design flow Q0 ratio) is reduced, the power is also reduced. Such as when Q = 0.65 Q0, the corresponding power is reduced to the original 80% or so, but compared with other modes of regulation, energy consumption is still in the first place.
(2) If the relative flow rate change is not large (or regulation depth is small), the difference in power consumption of several modes of regulation is not large. That is, the regulation of the energy-saving effect on the impact is not great, or even not only energy-saving, but due to the existence of more power consumption of the regulating device (such as hydraulic coupler).
(3) In general, the greater the depth of regulation, the more significant the energy saving effect. Therefore, it is important to choose the regulation carefully in order to obtain the maximum benefit.
(4) The variable speed regulation curve is close to the ideal curve. Therefore, the variable speed regulation is superior, especially the use of frequency motor speed control energy saving program is the best, but need to install additional frequency conversion device. For small and medium-capacity frequency control is recommended to actively try; due to high-capacity, high-voltage frequency control devices are more expensive, should be combined with the specific circumstances, a comprehensive comparison, to decide on the trade-offs. In short, both the regulatory performance should be considered, but also consider the initial investment in equipment, reliability and economy, etc., a comprehensive evaluation of the advantages and disadvantages of regulation.
