How to solve the problem of wind turbine stall during the operation of marine fans using oil pump gearboxes?
When using an oil pump gearbox - when using a fan, pay attention to the pressure condition of the fan, the relationship between the pressure coefficient and the incident angle λ in a stable state, and when the incident angle is greater than a certain value.
Using an oil pump gearbox - changing the incident angle, there is a region where the pressure coefficient shows a gradient decrease; If the vibration occurs at the blade in the flow field.
Ship auxiliary gear box - At this time, the aerodynamic force undergoes cyclic changes. When the pressure coefficient gradient of the ship's auxiliary gearbox is positive, it is equivalent to the aerodynamic force acting on the blades in the opposite direction, and the system is stable. When the pressure coefficient gradient is negative, it is equivalent to the aerodynamic force doing positive work on the blades.
Ship auxiliary gearbox - In such a situation, the phenomenon of wind turbine stall is prone to occur. Is there any solution for the problem of ship auxiliary gearbox?
The design of marine auxiliary gear box - marine fan requires the fan to be used under stable conditions of inlet pressure, inlet temperature, speed, and flow rate, and only in this way can the effectiveness of the fan be maintained.
Ship auxiliary gear box - However, if the opening of the inlet guide plate of the fan is not adjusted properly or the impeller flow channel, airflow channel, filter, etc. are blocked, it will result in the actual flow rate being less than the design flow rate.
Marine generator gearbox - The direction of the airflow entering the impeller changes, and the airflow impacts the working surface of the blades. As a result, a vortex or gas is formed near the non working surface of the blades in the marine generator gearbox. There are many reasons for the rotational deceleration of the centrifugal fan in the marine generator gearbox, but as long as we understand these reasons, we can.
Marine generator gearbox - a solution can be found. When using the wind turbine, we should try to operate it in a standardized manner as much as possible, which can reduce the occurrence of many faults.
