    80kpa refers to roots blower.

    The pressure difference between the air outlet and the air inlet is usually called a boost, and the pressure of the air inlet is generally one standard atmosphere.

    The calculation is 101kpa, but the outlet is also affected by atmospheric pressure, and the size is equal to 101kpa, plus the 80kpa, which is the pressure of the outlet, but because the import and export are affected by atmospheric pressure, and they cancel each other out equally, so it is usually just said that the pressure is 80kpa.

    If the inlet pressure (excluding atmospheric pressure) is the outlet pressure of 80 kPa plus the original pressure. Got it?

    The inlet pressure is 80kpa, no problem The inlet of the natural gas fan used in the glass production line designed and manufactured last time was 1 bar.

    Like yours, the use has the nature of a vacuum pump, and the inlet pressure of the roots vacuum pump is generally about 49kp, which mainly depends on what system you are using here. It would be better to explain the whole situation.

    80kpa is the pressure difference, and if the air intake is pressurized, just take 80 and subtract it.

    The maximum pressure of the domestic roots blower can reach 1 kg, and the normal is 0 8 kg.

    Imported roots blower, a kilogram, Japanese production of 30kw medium price at about 17,000 yuan, and the main difference between the working principle of the air compressor, the fan rotates, the piston of the compressor, the roots blower is more efficient than the compressor, the air volume is large, and it is easy to maintain.

    But unlike compressor pressure, low back pressure roots blowers are often used to replace compressors, but this requires or a high-pressure compressor.

    The maximum pressure of the domestic roots blower can reach 1 kg, generally only kilograms, the imported small Japanese is powerful, I have seen a can reach the kilogram, produced in Japan! The middle price of 30kw is about 17,000 yuan, the difference between him and the air compressor is mainly in the working principle, the fan is rotating, the compressor is the piston, the roots fan is more efficient than the compressor, the air volume is large, and the maintenance is convenient, but the pressure is not as good as the compressor, and the roots fan is often used to replace the compressor in the place of low pressure, but the compressor is still used in the case of high pressure.

    Domestic roots blower.

    The maximum pressure can reach 1 kg, and the normal is 0 8 kg.

    Imported roots blower.

    A kilogram, Japan produces 30kw at a medium price of about 17,000 yuan, and an air compressor.

    The main difference in the working principle is that the fan rotates, the piston of the compressor, and the roots blower is more efficient than the compressor, with a large air volume and easy maintenance.

    But not as high as the pressure of the compressor, low back pressure.

    Roots blowers are often used to replace compressors, but this requires or a high-pressure compressor.

    1.It affects the normal operation of the positive and hidden rise of the fan, so that the machine fails. Stove Burning Old 2

    Increase the wear of the fan impeller and affect the service life of the fan. 3.If the wind pressure is too high, it may cause the deformation of the fan housing and damage the fan.

    4.Excessive wind pressure will affect the efficiency of the fan impeller and reduce the efficiency of the fan. 5.

    Affect the energy utilization rate of the wind turbine and increase energy consumption.

    The pressure of the roots blower depends on the resistance applied, and it can work as long as it is within the tolerable pressure range.

    For example, if you aerate in a pool with a depth of 2 meters, the pressure of the air blown out is 20 kPa. At a depth of 3 meters, the pond becomes 30 kPa.

    As long as the output power of the motor can reach the load, it is fine.

    If the pressure gauge shows a pressure greater than it should be output, it may be due to a clogged pipe, clogged aeration head, etc.

    It is possible that the pipes are clogged and the pressure caused by the aeration head is too high.

    I didn't make it clear, so it's hard to answer, so please be more detailed. What is the effect of aeration? If the speed of the roots fan is stable and the temperature is normal, it may be that the aeration pipe and mouth are blocked, and the whole system needs to be checked to know.

  14. Anonymous users2024-01-28

    If the wind pressure is large, you can consider reducing the output of the fan, if the resistance is large, it is best to check the rotor, bearing, lubrication, and chamber.

  15. Anonymous users2024-01-27

    The speed of the roots fan is stable, and the air volume and air pressure should not be too large. Or the working pressure in the exhaust pipe is high, check whether there is any abnormality.

    Generally, a 5-meter pool pressure is just right, unless you are dealing with a very dense sewage!

    The performance parameters of roots blower should have the following points:

    1. The actual required air volume;

    2. Wind pressure in working condition;

    3. The shaft power of the motor;

    4. Corresponding to the speed of the model.

  18. Anonymous users2024-01-24

    The speed of the roots blower is 150 3000 rpm. The flow rate is cubic meters per minute, the pressure is kPa, the power is kilowatts, and the weight of a single machine is 100 9000 kg.

  19. Anonymous users2024-01-23

    <> roots blower is now directly used with the first selection system, only need to enter the flow rate, select the pressure, you can query the required model and motor power. Turn the complicated selection process into a fool's style, you can give it a try.

  20. Anonymous users2024-01-22

    There must be specific parameters, and the air volume and wind pressure are required to select the type.

  21. Anonymous users2024-01-21

    The pressure gauge data of the roots blower is reflected by the resistance of the pipeline.

    When there is excessive stress, there are several possibilities:

    1. The exhaust volume is reduced, and some outlet valves are closed or closed;

    2. It is caused by blockage at a certain position or outlet of the pipeline.

    Please check carefully to eliminate the problem before use, if you do this for a long time, the motor may be overloaded and burned out.

You don't know much about the mechanical characteristics of high-pressure fans, high-pressure fans can't adjust the wind pressure, only the air volume, and the wind pressure is determined by the load. When the speed of the fan is maintained at a certain level, the wind pressure will be small when the load is large, and the wind pressure will be large when the load is small. It is commonly known as the roots blower to be strong when it is strong, and weak when it is weak. >>>More

At that time, I chose to compare for a long time, and then I visited a few on the spot, and finally bought Jingong's roots blower under the comparison in many aspects, because it was more moderate, and now it has been used for a year and a half, and there has been no problem. You refer to it, in addition to Jingong, Pepsi, Changsha you can also refer to the comparison, for this kind of equipment do not have to be nitpicky, the leather is durable.
