1、 Product Overview
The HTFC-D type snail shell free curved cabinet centrifugal fan is a new product developed by our company through learning advanced foreign technology and absorbing, digesting, and improving it. The impeller material is high-quality carbon steel or aluminum alloy, which has the characteristics of high efficiency, low noise, light weight, compact structure, less space occupation, and smooth operation. At the same time, it can also have explosion-proof characteristics (aluminum alloy impeller). It is currently the new generation product for ventilation and air exchange in high-rise buildings.
2、 Product Features
1. The HTFC-D type snail shell free curved cabinet centrifugal fan has the characteristics of small volume, simple structure, and easy maintenance, especially as an ideal supporting product for purifying air conditioning and kitchen smoke exhaust.
2. The HTFC-D type snail shell free curved cabinet centrifugal fan has 13 specifications ranging from 250mm to 1000mm according to the impeller diameter. According to different user needs, the unit is equipped with two basic transmission modes: L-type direct transmission and P-type belt transmission. The L-type direct transmission fluid can be matched with a variable frequency motor for speed regulation to achieve stepless speed regulation. The motor of the P-type belt driven fan can be loaded outside the box, ensuring continuous operation for more than 60 minutes at a high temperature of 300 ℃, meeting the requirements for fire and smoke exhaust.
3. Silencing box body: It adopts a frame and box board assembly design. The frame is made of advanced metal cold bending unit and stretched in one go. The box board is a color coated board with a clean and beautiful surface and strong corrosion resistance. The inner layer is high-quality galvanized board, and the middle is filled with polyurethane foam material, which can further reduce noise. The product can be disassembled and installed on site.
3、 Product process
1. Impeller: The impeller consists of backward inclined circular arc blades, curved front plate, flat middle plate, and hub, and has advanced aerodynamic performance. All are produced using molds, welded with carbon dioxide gas shielded welding, and calibrated by a digital hard support dynamic balancing machine, achieving a balancing accuracy of G4.6 or above.
2. Box body: The box body material is rolled and formed by a metal cold bending unit, and the box plate is a composite structure. The outer layer is cut and bent from high-quality color coated plates produced by Baosteel. The inner layer of the box body is made of high-quality galvanized plates, and the middle is filled with polyurethane foam material, which has good noise reduction effect. The assembly method of the box board and profile is embedded, which improves the sealing performance of the fan, ensures the soundproofing effect of the box board, and reduces the air leakage of the fan.
3. Chassis: The fan chassis is made of heavy-duty metal cold bending units and stretched into a C-shaped shape. C-shaped steel is a new type of steel with excellent cross-sectional mechanical properties, evolved from channel steel. It has good mechanical properties and a beautiful and elegant appearance.
4. Accessories: The bearing adopts the UKP series tapered bushing produced by Fujian Nan'an Bearing Co., Ltd., which is convenient for installation and maintenance. The V-belt adopts the "Chaoyang" brand belt produced by Hangzhou Zhongce Rubber Products Co., Ltd., ensuring the service life of the fan.
5. Maintenance door: The fan is equipped with detachable maintenance doors with handles, making maintenance very convenient.
6. Assembly: After the fan is assembled, the vibration velocities of the X, Y, and Z axes are all less than 5.6mm/s.
7. High temperature resistance performance: The fire smoke exhaust cabinet centrifugal fan has a motor installed outside the box, completely isolated from high-temperature airflow, ensuring that the fan can operate normally for more than 60 minutes under high temperature conditions of 300 ℃, fully complying with national fire safety regulations.
