Jiangsu Weigu fluid introduction: How to increase the pressure of Roots blower? 

 On the pressure of the Roots fan, we first need to know such a problem, that is: the pressure gauge of the Roots fan refers to the pressure of the front pipeline, the Roots blower belongs to the positive displacement rotary fan, so the pressure of the front pipeline is the pressure of the Roots blower, and the pressure gauge shows the pressure of the front pipeline. Usually we say that the pressure of the Roots fan, in fact, refers to the pressure resistance of the Roots fan, that is, the Roots fan can withstand the maximum pressure, can not carry a certain pressure value, the Roots fan will reverse, there will be a motor burn out situation, we said before to increase the pressure of the Roots fan, in fact, refers to: "Increase the pressure resistance of the Roots fan." So how to improve the pressure resistance of Roots fan? 

 1. Replace the motor This is the most direct method, but also the most effective way, the same head, replacing the motor with a larger power, the pressure resistance of the Roots blower will be directly and effectively improved, and this is often the most effective way without changing the head of the Roots blower. 

 2. Replace the model If under a certain pressure, the maximum parameter of the fan has been exceeded, then we recommend directly replacing the larger Roots fan to combat excessive pressure in the pipeline, which is also the safest method. A single replacement of the motor may also face problems with model and energy consumption, while replacing the Roots fan model will not face such problems. 

 3, change the speed can increase the pressure? On the Internet, Sanniu Fan Xiaobian, see many netizens ask, can changing the speed of Roots fan increase the pressure of Roots fan? Here, Sanniu fan and everyone explain that modifying the speed of the Roots fan can only change the air volume of the Roots fan, and has no effect on the improvement of pressure. 

 4. Can the replacement of the pulley increase the pressure? Replacing the pulley is a way to modify the speed of the Roots fan, so increasing the pressure is not feasible. Roots fan selection parameters have these! 

 5, if the Roots fan overpressure, what to do? Overpressure and insufficient pressure are two different things, we have been talking about the problem of insufficient pressure, how to increase pressure. And overpressure, we do not need to replace the Roots fan, install a pipe on the pipeline, and reduce the pressure of the pipeline, but there is only one disadvantage, that is, no energy saving!
