Details
High pressure fan, generally used for forging furnace and high pressure forced ventilation, and can be widely used for conveying materials, conveying air and non-corrosive, non-spontaneous combustion, non-viscous substances of gas. The medium temperature is generally not more than 80℃, and the dust and hard particles contained in the medium are not more than 150mg/m³. For flammable and explosive gas conveying, the impeller can be processed with aluminum alloy to prevent sparks from being caused during operation, and the motor can be an explosion-proof motor with the same performance parameters as the common motor. This kind of high pressure fan has high efficiency, low noise, flat performance curve and wide high efficiency area.
Second, product features
1.It can output higher gas pressure and provide more gas flow with lower noise.
2.In the case of using the integral bracket, the installation is very simple and basically does not require the support of professional technicians.
3.The motor shaft is flexibly connected to the drive shaft, so there is no need to frequently tension the belt or replace the belt, and the maintenance workload is small.
4.Impeller diameter below 1400mm running in room temperature fan system, no additional configuration of bearing cooling device, reducing the user's investment and maintenance workload.
5.When the airflow resistance increases, the motor load will be automatically reduced and will not burn the motor.
6.High-pressure fans are made of high-quality carbon steel, and stainless steel or other metal materials can be used according to user requirements.
7.After the production of high-pressure fan is completed, it is tested by operation test and vibration value, and it runs reliably.
Use of fan
8-09, 9-12 high-pressure centrifugal fan is a special fan with melting rate of 1, 2, 3, 5, 7t / h iron furnace, can also be used as a variety of melting furnaces, forging furnace blast and transport non-corrosive, non-spontaneous combustion, non-viscous substances of gas, other similar performance can also be used, but the temperature of the transport medium shall not exceed 80 ℃, the medium contains dust and Hard particles not more than 150mg/m3.
Second, the type of fan
1. 8-09 and 9-12 type fans are single inhalation, 8-09 type fans, our company designs № 6.8A, 7.1D, 8D, 8.5D, 9D five models. 9-12 type fans, our company designs № 6.8A, 7.1A, 7.1A, 7.5D, 9D five models. There are six models № 6.8A, 7.1A, 7.4D, 7.7A, 8D, 9D.
2, 8-09. 9-12 fan casing made of clockwise rotation or counterclockwise rotation of two types.
3, the fan's export position to the casing of the export angle, "clockwise", "counter" fan casing made of 0 degrees, 90 degrees, 180 degrees.
Third, the structure of the fan
The fan is mainly composed of impeller, casing, air inlet, transmission group, seal, seat, etc.
1.Impeller: The impeller is designed according to the new theory of high-efficiency forward-facing fan, and after the impeller is formed, it is corrected by static and dynamic balance, so it runs smoothly.
2. Casing: Welded into a worm-shaped casing with common steel plate.
3. Air inlet: made into a convergent streamline overall structure, fixed with bolts on the front cover.
4. Transmission group: It is composed of spindle, bearing box, coupling and so on. The main shaft is made of high quality steel, and the bearing box has an overall structure. Adopt rolling bearing, and the rolling bearing is lubricated with grease.
