Product Introduction
The CD/CG Series Centrifugal Blower is a new generation of centrifugal blower products that our company has carefully designed and developed to meet user needs, based on years of design and manufacturing experience.
This series of products is developed based on years of design and manufacturing of multi-stage centrifugal blowers, taking into account the requirements for conveying different media and incorporating multiple patent technologies to develop highly efficient and energy-saving products.
It is the latest product that integrates advanced technologies from both domestic and foreign countries.
Structural of Product
The CD/CG series centrifugal blower consists of upper and lower casings, rotor parts, bearing parts, and an oil lubrication system. This series of products is widely used in blast furnace air supply systems, mining flotation, SO2 gas transportation (acid production from flue gas), coke oven gas pressurization, generator gas pressurization, chemical gas production and other processes. |  |
Casing The fan casing adopts a horizontal split structure, and the stator casing is divided into two roughly symmetrical parts, which are tightly fixed together by bolts and other connecting components. Each part is made of high-quality cast iron resin sand casting, and undergoes strict stress relief annealing treatment to reduce deformation. It is processed on proprietary equipment with high precision and good coaxiality, ensuring smooth operation of the rotor part. |  |
Rotor The rotor part is composed of a main shaft, impeller, shaft sleeve, balance disk, and coupling. The main shaft and impeller of the fan are both made of high-strength alloy steel. Perform overall dynamic balance correction on the rotor to ensure its stability and reliability. |  |
Impeller The impeller consists of blades, wheel cover, disc, and shaft. For some occasions that require the transportation of special gases, the overall material of the impeller willbe made of high-performance materials such as stainless steel and titanium alloy. After strict precision machining, the impeller undergoes dynamic and static balance correction and overspeed testing. |  |
Slide bearing Sliding bearings provide stable support for the rotor, ensuring its stable operation during high-speed rotation. |  |
Bearing housing Bearing housing material is cast iron, they are disposed on two sides of blower. Installing and replacing bearings are easy. There are thermal hole and vibration hole on the bearing housing. |  |
| lubrication system The lubrication device consists of an oil tank, an oil pump device, an oil filter, a tubular oil cooler, as well as an electrical control box, instruments, pipelines, valves, etc. |  |
Control system Electric company can provide good-operation LCP and MCP, Via MCP, many parallel blower can achieve remote monitored and local control. |  |
