详细说明
一、主要组成部分的结构特征
4－68型风机的№2.8-5主要由叶轮、机壳、进风口等部分配直联电动机组成。№6.3-20除上述部分外还有传动部分。
1、叶轮：由12片后倾翼形叶片焊接于孤锥型的轮盖与平板型的轮盘中间。均用钢板制造，并经过静动平衡较正，空气性能良好，效率高，运转平稳。
2、机壳：机壳是普通钢板焊接而成的蜗形体，机壳作成两种不同型式，№2.8-12.5机壳作成整体，不能拆开。№16、20机壳作成三开式，除沿中分水平面分为两半外，上半部再沿垂直中心线分为两半，用螺栓连接。
3、进风口：作成收敛式流线型的整体结构，用螺栓固定在风机入口侧。
4、传动组：由主轴、轴承箱、滚动轴承、皮带轮或联轴器等组成。主轴由优质钢制成。№6.3—12.5四个机号风机，轴承箱整体结构，在轴承上装有温度计和油标，№l6、20两个机号风机用二只并列轴承座，在轴承座上装有温度计，采用轴承润滑脂润滑。
二、风机的型式：
1、本风机制成单吸入，机号有：№2.8、3.15、3.55、4、4.5、5、6.3、8、10、12.5、16、20等十二个机号。
2、每种风机又可制成右旋转或左旋转两种型式，从电动机一端正视，叶轮按顺时针方向旋转，称为右旋转风机，以“右”表示。按逆时针方向旋转，称为左旋转风机，以“左”表示。
3、风机的出口位置，以机壳的出风口角度表示。“左”、“右”均可制成0o，45o，如135o，180o，225o共六种角度。
4、风机的传动方式：有A、B、C、D四种，№2.8-5采用A式，以电动机直联传动，风机的叶轮、机壳直接固定在电动机轴和法兰盘上(电动机用D2／T2型)；N06.3-12.5采用悬臂支承装置，又分为C式(皮带传动皮带轮在轴承外侧)和D式(用联轴器联接传动)两种传动方式；№l6、20为B式悬臂支承装置，皮带传动，皮带轮在轴承中间。
三、风机的用途：
4-68型离心通风机(以下简称风机)可作为一般通风换气。其使用条件如下：
1、应用场所：作为一般工厂及大建筑物的室内通风换气，既可用作输入气体，也可用作输出气体。
2、输送气体的种类：空气和其他不自燃的、对人体无害的、对钢铁材料无腐蚀性的气体。
3、气体内的杂质：气体内不许有粘性物质，所含的尘土及硬质颗粒物不大于150毫克／立方米。
4、气体的温度：不得超过80度。
Zibo Jinhao Blower Co., Ltd: Our company was incorporated in 1999. Since the establishment of our company, we have been trying our best to build a first-class fan manufacturer with standardization, specialization and modernization with high standards and high starting point. We met with China University of Mining and Technology, Northeast University of Technology, Xi'an Jiaotong University, Institute of Fluid, Shandong University and other institutions of higher learning to establish long-term technical cooperation and the introduction of new technologies and new products, strong technical force, in the domestic first-class level.
In the consideration of customers, the purpose of customers urgently need ,using new technologies, introduction of new products, and greatly enhance the fan design technology and rich experience in manufacturing expertise, the development of nearly 100 series, more than 2,000 variety of specifications required models, with its new structure, low noise, high performance, stable operation and other characteristics, are widely used in China's metallurgical, nonferrous metals, gold, chemicals, building materials and other types of mine ventilation site.
Cooperation with Shandong University in 2009 ,set up a "Shandong Jinhao energy-efficient R & D center" to make it more powerful technical force for the development of mine ventilation fan, ventilation system optimization design, ventilation optimization selection design, supporting electricity Control (soft starter control, inverter control) technology, on-line monitoring and remote control and video surveillance system development provides a strong technical support.
Our company cooperated with Chongqing Research Institute of Coal Science Research Institute to build the latest on-line fan test system which is the most advanced in China at present. Through the on-line testing, the main performance indexes of our products surpass the national designated targets. For my company's technology development, factory ventilation fan provides a strong technical support.
My company's products are exported to over 20 provinces (cities, from the rule of the area), they are improving the working environment of workers, to provide adequate fresh air flow and ensure safety in production at the same time, greatly reducing the ventilation power consumption, energy-saving effect is remarkable. The company is committed to the development and production of coal mine explosion-proof energy-saving main fan, explosion-proof coal mine explosion with local fans, metal mine energy-saving ventilation fans, gas pressurized centrifugal blower, universal centrifugal and axial fans, power station Centrifugal fans, textile axial fans and high temperature fans and other products.
The company also produces: radiators, heaters, cooling pipes, heat exchangers and other drying equipment. Widely used in light industry, paper, starch, silica gel, coating, printing and dyeing, textiles, electricity, medicine, metallurgy and other industries.
