According to the principle of Foshan Shenglin Eletronic, when the impeller rotates with the shaft, the gas between the blades also rotates with the impeller to obtain inertial centrifugal force, and the gas is thrown out from the outlet between the blades. The thrown out gas squeezes into the casing, so the pressure of the gas in the casing of Foshan Shenglin Eletronic centrifugal fan increases, and finally it is guided to the outlet and discharged. After the gas is thrown out, the pressure in the central part of the centrifugal fan impeller decreases. The outside air can be inhaled from the suction port of the fan through the hole in the center of the front disc of the impeller, and the air is continuously delivered.
Foshan Shenglin Eletronic centrifugal fan motor current is too large: In the case of Foshan Shenglin Eletronic Group centrifugal fan working, in order to better ensure that it is in all normal operating conditions, everyone must show it all normal power supply voltages, but There are also some factors that will cause the current of the centrifugal fan motor to rise. For example, due to the danger of strong vibration of the rolling bearing box, or when the Roots blower is started, the water conservancy gate of the exhaust pipe is not closed immediately, or the speed ratio of the main shaft bearing of Foshan Shenglin Eletronic centrifugal fan is too large, exceeding the standard value, or oblique flow The input voltage of the fan motor is too low, or the power supply of the single project of Foshan Shenglin Eletronic centrifugal fan motor is turned off, etc. , These problems will cause the current of the motor lift.
The temperature rise of the rolling bearing of Foshan Shenglin Eletronic centrifugal fan is too high: For this part, we can consider it from four levels, it may be because the force distance between the rolling bearing cover of Foshan Shenglin Eletronic centrifugal fan and the seat connecting bolt is too high Large or too small; because the rolling bearing box has a strong vibration problem; the roller bearing of Foshan Shenglin Eletronic centrifugal fan is damaged; because of insufficient lubrication, or there are more residues in it.
