4-68 centrifugal fan
4-68 centrifugal fans (hereinafter referred to as fans) can be used for general ventilation. Its service conditions are as follows:
1. Application site: As the indoor ventilation of general factories and large buildings, it can be used as both input gas and output gas.
2. Types of gas to be transported: air and other gases that are not spontaneous combustion, harmless to the human body, and non-corrosive to steel materials.
3. Impurities in the gas: there shall be no viscous substances in the gas, and the dust and hard particles contained in the gas shall not exceed 150 mg/m3.
4. The temperature of gas shall not exceed 80 ºC.
2. Fan type:
1. The fan is single suction, and the machine numbers are № 2.8, 3.15, 3.55, 4, 4.5, 5, 6.3, 8, 10, 12.5, 16, 20, etc.
2. Each type of fan can also be made into two types right rotation or left rotation. When viewed from one end of the motor, the impeller rotates clockwise, which is called the right rotation fan, which is represented by "right". counterclockwise, which is called left rotation fan, and is represented by "left".
3. The outlet position of the fan is expressed by the outlet angle of the casing. Both "left" and "right" can be made into 0o, and 45o, such as 135o, 180o, and 225o.
3. Structural characteristics of main components
№ 2.8-5 of 4-68 fan is mainly composed of an impeller, casing, air inlet, and other parts equipped with a direct-connected motor. № 6.3-20 has a transmission part in addition to the above parts.
1. Impeller: It is composed of 12 backward-inclined wing-shaped blades welded between the single-cone wheel cover and the flat-plate wheel disc. They are all made of steel plates and have been calibrated by static and dynamic balance, with good air performance, high efficiency, and stable operation.
2. Casing: the casing is a volute formed by welding ordinary steel plates. The casing is made into two different types. № 2.8-12.5 casing is integral and cannot be disassembled. № 16 and № 20 casings are made into three open types, and the upper part is divided into two parts along the vertical centerline, in addition to being divided into two parts along the horizontal plane of the split, which are connected by bolts.
3. Air inlet: it is made into a converging streamlined integral structure and fixed on the inlet side of the fan with bolts.
4. Drive group: composed of main shaft, bearing box, rolling bearing, pulley or coupling, etc. The spindle is made of high-quality steel. № 6.3-12.5 fans of four unit numbers are of integral structure, with a thermometer and oil pointer installed on the bearing. № 16 and № 20 fans of two unit numbers are equipped with two parallel bearing blocks, with thermometers installed on the bearing block and lubricated with bearing grease.4-68

Company Profile
Zibo Hengding Fan Co., Ltd. Is located in Industrial Park, Beijiao Town, Zhoucun District, Zibo City, Shandong Province, China. The company covers an area of 12,000 square meters and a construction area of 8,000 square meters. The company has total assets of 27 million RMB and 186 employees, 46 engineers, and technicians. It has passed ISO9001 quality management system certification and has maintained long-term technical cooperation relationships with many colleges and universities, such as Xi'an Jiaotong University, Tianjin Nankai University, and so on. Now, it has developed into a modern ventilation equipment manufacturing enterprise with first-class testing and producing equipment, high-quality and excellent production molds, strong scientific research and development strength, a strict quality management system, and gradually perfected development. The company has 15 years of production experience, with an annual output of 5,000 sets of ventilators.
With the market demand as the development direction, the company has always adhered to independent R&D and continuous innovation. Now it has developed into a modern environmental protection, and ventilation equipment enterprise, which mainly consists of mine fans, coal mine ventilators, and centrifugal ventilators. There are more than 50 series of ventilator products with more than 600 specification models, widely used in many industries, such as mines, coal mines, oil fields, chemical industry, kilns, metallurgy, boiler, textile and building materials, etc. The company's products are sold continuously with reliability in 29 provinces, cities, and autonomous regions of China, as well as Vietnam, Indonesia, Russia, Serbia, Pakistan, Kazakhstan, Tajikistan, Iraq, Saudi Arabia, and other countries.
We are willing to cooperate with all the new and old customers to create brilliance with first-class quality, reasonable prices, and a perfect service system.
General Manager Wang Baiqing welcomes friends from all walks of life to visit our company for inspection and guidance.
Strict quality standards, precision machining, and other spare parts and design maintain product stability, strictly select product parts suppliers, and perfect after-sales service system to allow customers to enjoy a new experience
Our company has introduced the latest research results of the Chinese Academy of Sciences, C4-II ternary flow wing twisted blades, which have high aerodynamic efficiency.
The surface of the ventilator impeller blade is sprayed with advanced super-resistant (CN) metal material to form a wear-resistant, anti-corrosion protection layer on the surface of the blade. The wear resistance of the blade surface is 10 to 50 times higher than that of the ordinary carbon steel material, thereby greatly prolonging the service life of the blade.
Our company adopts computer simulation calculation and quasi-ternary flow theory, we correct the blade shape and calculate coordinate parameters of its shape, then make the core mold and the external pressure mold of the blade, and the blades are formed by hot pressing. According to a large number of experiments, the tilting blade has a larger lift-to-drag ratio than the original organic blade type and is the best choice for the airfoil blade.
The blades are welded with high-strength carbon steel material. The petiole is treated with high-quality carbon steel. So that the blade maintains the strength and rigidity of the steel blade when ensuring the corrosion resistance and wear resistance of the blade. Moreover, it effectively protects the blade from corrosion resistance and wear resistance in a humid air environment, and improves the operating life of the ventilator.
Quality assurance measures:
In long-term production management, our company has formed a set of standardized process control measures and control points, which can provide users with high-quality products in all directions. Our company has a good reputation and is an enterprise that users can absolutely trust.
Our company has obtained the IS09001 certification from the International Organization for Standardization (see Enterprise Qualification Materials for details). We strictly standardize the operation process and control points of product manufacturing
