The maximum pressure of the domestic Roots blower can reach 1 kg, which is generally 0.8 kg. The imported small Japan is powerful. I have seen one that can reach 2.5 kg. It is made in Japan! The middle price of 30KW is about 17000 yuan. The difference between it and air compressor is mainly in the working principle. The fan is rotating and the compressor is piston. Roots blower is more efficient than the compressor, with large air volume and convenient maintenance, but its pressure is not as high as the compressor. Roots blower is used to replace the compressor in places with low pressure, but the compressor is still needed in the case of high pressure.
The application of roots blower is very flexible. The outlet pressure of roots blower can be adjusted, so it can cope with various operating environments. When you carefully observe the application of Roots blower, you will find that it can not only be used in aquaculture oxygenation, sewage treatment aeration and other places. It can also play an important role in cement transportation and other industries.
What are the characteristics of Roots blower? It is a device that can control noise. Because some equipment vibrates greatly during operation, it is easy to make a lot of noise. However, Roots blower has been improved, with low vibration and noise. Now more and more people like Roots blower because it is a kind of equipment with stable operation performance. Because some equipment may be flexible at the beginning, but after a long time, it will cause failure due to wear and tear. However, Roots blower impeller is not worn, and the fan has a long performance, so the service performance is stable and the service life is long.
The common solution to low pressure of roots blower is to replace a larger motor, but the flow may decrease, so the speed generally needs to be increased. The pressure of roots blower is not the pressure that roots blower can produce, but the pressure that roots blower can load. The low pressure of roots blower is actually the insufficient pressure and force under the normal operation of the fan. If forced use, the motor will be damaged. Therefore, if you want to increase the pressure, you must replace the powerful and high-power motor.
To change the pressure required by the system is simply to change the diameter of the outlet of the three blade roots blower. Large pressure drop, small pressure rise. The pressure relief valve can be installed on the blower. The pressure relief valve can accurately and maintain the constant safe and stable pressure. Once overpressure occurs, the pressure relief valve can be fully opened to relieve pressure in time.
Adjust the clearance of the three blade roots blower. When installing, put the feeler gauge between the impellers, and then install the gear. During gear installation, change the feeler gauge between each contact surface of the impeller to keep the clearance consistent. There is a small gap between the cylinder and rotor of the three blade roots blower. Generally, the gap is about a few tenths of a millimeter. Since they do not rub against each other, they can run at high speed to obtain large air volume or exhaust speed. As the three blade roots blower does not need lubricating oil in its inner cavity, it has simple structure, stable operation and stable performance, and is suitable for many purposes.
Since the wind pressure of Roots blower is not limited by the fan speed, the wind pressure can remain unchanged regardless of the speed change. The air volume is in direct proportion to the fan speed. Within a certain pressure range, the pressure changes with the system, and the pressure changes with the system resistance, which is adaptive; It has the hard exhaust characteristic of forced gas transmission, that is, when the pressure changes, the flow changes little
I believe that after reading the above contents, you should also understand the method of adjusting the pressure of Roots blower. I hope it will be helpful to you.
