1. How high is the maximum wind pressure of the high-pressure fan?
The wind pressure of the high-pressure fan is one of its important parameters, and the wind pressure will directly affect the performance of the high-pressure fan. The pressure generated by the high-pressure fan is much larger than that of the ordinary fan, so how high is the pressure of the high-pressure fan?
Generally speaking, different types of high-pressure fans have different pressures. Usually, the high-pressure fan with 3 impellers can generate the highest pressure. Take the 4GH 630-H67 high-pressure fan as an example. The rated pressure that can be generated is 104kpa, which is not the limit value, and the limit value can reach 150kpa.
Second, what is related to the wind pressure of the high-pressure fan
The wind pressure of the high-pressure fan is affected by many factors, including the model of the high-pressure fan, the The diameter of the wind wheel, the speed of the high-pressure fan, etc. Generally, the fan with a large diameter and a high speed has a relatively high wind pressure.
Of course, it is not that the higher the wind pressure, the better the high-pressure fan, because the higher the pressure, the greater the power, noise, and vibration. When choosing, you should choose the appropriate wind pressure according to the needs of the field of use. If the product is selected too large, it will increase our purchase cost and cost of use; if it is selected too small, it will not meet the requirements, especially the fan of poor quality, which may burn out.
Three, what to do if the high-pressure fan does not go up the wind pressure
When using the high-pressure fan, sometimes the wind pressure of the high-pressure fan cannot go up , the rated pressure cannot be reached. When this happens, we can first check the cause of the failure, and then repair it. The common causes of failure and repair methods are:
1. The speed of the pump head is reduced: possible It is the power supply voltage is low or the motor is faulty, the power supply should be debugged or the motor should be repaired.
2. Increase the resistance of the pipe network: reduce the resistance of the pipe network.
3. Change of working state: adjust the working state of the high-pressure fan.
4. Motor rotation is reversed: the motor is rewired.
