Mingfeng Machinery explains the components of the centrifugal blower.
Release time:
2022-05-27
There are many types of blowers, and multi-stage centrifugal blowers are one of them. Multi-stage centrifugal blowers mainly consist of a stator, rotor, and rotating device. They are widely used in wastewater treatment, smelting blast furnaces, coal washing plants, mining flotation, chemical gasification, vacuum, and other fields, and can also be used to transport other special gases. Today, I will introduce the components of the multi-stage centrifugal blower. 1. Compact structure, beautiful appearance, good stability, and easy installation and maintenance. 2. Smooth operation, the optimized impeller reduces axial force to a low level, and the impeller efficiency is high. After static and dynamic balance correction, the whole machine runs smoothly, with a bearing amplitude of 0.04mm and no damping devices. 3. Low noise, during the operation of the blower, there is no mechanical friction, and the reasonable blade profile reduces the sound to a minimum. The noise generated by the multi-stage centrifugal blower is high-frequency noise, which can be isolated by any obstacles, so there is almost no noise outside the blower room. 4. Oil-free machinery, the bearings are lubricated with grease, and the bearing life exceeds three years. The fan does not produce oil and gas during operation. Special lithium disulfide molybdenum grease is required to lubricate the bearings. 5. The special composite profile of the impeller reduces internal leakage and improves volumetric efficiency. 6. Easy to adjust, the inlet butterfly valve adjusts the flow, and the outlet butterfly valve adjusts the pressure. 7. Usually, a two-pole asynchronous motor is used, but a four-pole motor can also be used for driving. Depending on the user's power grid, motors of different voltages can be used. 8. Sealing, in addition to the inlet ring, labyrinth seals are also installed at both ends of each stage impeller and between the stages and the casing to prevent gas leakage. 9. Cooling, the exhaust bearing seat has both air-cooled and water-cooled structures. As the impeller gradually compresses the gas, the temperature of the exhaust casing is much higher than that of the intake casing. There are air-cooled or water-cooled devices in the exhaust bearing seat to extend the bearing's service life. 10. Bearing temperature control alarm, the accessory is equipped with a temperature control box, connected to the bearing through a PT100 resistor. When the bearing temperature exceeds the set temperature, the temperature control box will automatically alarm.
