Usage of K58 type mine fan:
The K58 (1K58 and 2K58 series) mine axial flow fan has the characteristics of high efficiency, good performance, and wide high-efficiency zone, which is suitable for the actual needs of most mines in China and has reached the advanced level of similar domestic products. The performance and structural type of this type of fan are suitable for both the renovation of ventilation equipment in old mines and the expansion of new mines. It is an ideal ventilation equipment for coal mines, metal mines, and other occasions.
Performance parameters of K58 mine fan:
1. Performance parameters of the fan
Serial number: No12、No18、No24、No27、No28、No30、No32、No36
Technical parameters (performance range): Flow rate Q=10m3/s~460m3/s
Static pressure Pst=700Pa~3000Pa η st=≥ 80% η stmax=84.3%
Functional features: Good performance, wide efficient range; High static pressure efficiency, smooth operation, and easy installation and use.
2. Selection of fan performance
Performance selection is based on comparing the specific parameters of the required working conditions (air volume, air pressure) of the ventilation site with the characteristic curve (or performance table) of the fan to achieve a reasonable selection of the ventilation fan. The characteristic curve of a ventilation fan is a curve that reflects the relationship between air volume, air pressure, efficiency, and power at a given speed. It indicates the various working performance and variation laws of the ventilation fan. When choosing the performance of a ventilation fan, the following points should be noted:
① Firstly, it is necessary to determine the actual operating parameters required on site, such as flow rate, pressure, speed, etc., and whether they are within the working range of this model of fan
② The required operating parameters on site - operating points - should be selected within the high-efficiency zone of the ventilation fan characteristic curve to improve operational efficiency and save electricity
③ When consulting the characteristic curve of K58 mine axial flow fan, special attention should be paid to the corresponding speed, and it is not allowed to arbitrarily increase the operating speed of the fan
④ The flow rate Q and static E of the fan, Pst、 The relationship between power N and speed n is as follows
If there is a significant change in the rotational speed n, atmospheric pressure P, gas temperature t, etc. compared to the standard state, the conversion formula is as follows:
⑤ The characteristic curve of a fan is the equipment device characteristic curve, and its efficiency is the static pressure efficiency of the equipment device.
3. Selection of electric motor
① When selecting an electric motor, users should consider the characteristics of the dragged machinery and the on-site power grid and electrical control characteristics. Based on the user's experience, the model of the electric motor should be selected rationally. The K58 mine axial flow fan has the characteristic of releasing and returning air, and users should consider meeting the equipment's usage requirements when choosing an electric motor.
② The power of the electric motor can be calculated according to the following formula:
In the formula: N - power of the electric motor (KW)
Pst fan static pressure (Pa)
Q - Flow rate of fan (m3/s)
η -- Static pressure efficiency of fan equipment (%)
K - The reserve coefficient of the electric motor is taken as K=1.2
