Working conditions and compressive strength of axial flow fan castings
- Jul 30, 2018 -

The axial flow fan castings mainly adopt the simple structure of the fan directly connected with the impeller, which effectively changes the current axial extraction ventilation of the coal mine and the complex structure fan which adopts belt transmission or long shaft transmission. Wholesale castings are good for operation and maintenance.

The axial flow fan castings are safely closed on the outside of the motor and have a certain temperature resistance of the closed heat shield and the air pressure balance tube, so that the motor can always run in the gas-free air, meeting the requirements of the coal mine related explosion-proof regulations. It is fully adapted to the direct-coupled transmission and installed in the mine to transport air containing gun smoke, dust and humidity, and a special protection starter cabinet.

The axial flow fan castings will be effectively supplied according to the needs of their users. When the fans of various specifications are shipped from the factory, they can be supplied with special protection starter cabinets. The electronic control device can reliably protect the motor from overload, voltage loss, short circuit and other faults. There is a device for quickly reversing the motor. When the fan needs to reverse the wind, press the stop button first, then press the reverse button after the fan stops.

In the design of axial flow fan castings, in addition to determining the geometry and size of the casting according to its working conditions and metal material properties, the rationality of the design must be considered from the perspective of casting alloy and casting process characteristics, ie Significant size effects and problems such as solidification, shrinkage, stress, etc., to avoid or reduce the occurrence of defects such as segregation, deformation, cracking of the casting.
