1. Overview
1.1. Due to the L3-2A hybrid fan, the impeller adopts a twisted blade with a meridional and radial characteristics, which is welded and eliminated on the impeller. The inlet is connected to the wind turbine as a whole with a radial line for noise reduction. It is equipped with a guide vane, which has good air distribution and stable pressure. It is a type of wall fan that is opposite to the axis and centrifugal fan.
1.2. The PYHE-14A type reduction fan is an improvement on the L.3-Z23 fan, and the electric Kai uses a high resistance motor. It is not equipped with a dedicated motor cooling system. The product has been tested for high temperature resistance by the National Fire Protection Adhesive Preparation and Cooking Supervision Quality Supervision Center according to Cl211-1999 "Ten Thousand Methods for High Temperature Resistance Test of Anti stress Exhaust Fans". It can operate continuously for more than 60 minutes at a medium temperature of 300 ℃ and a temperature of 100 ℃ for 20 hours/time without damage, and can be used for ventilation
Dual use of moisture removal.
1.3. Fans are divided into 2 according to their machine numbers. There are a total of 24 types of membrane grids, ranging from 450 to 13500m '/h, with a total pressure range of 50 to 19oOra
1.4. In order to meet the user's demand for reliable performance at different operating points, the fan can be equipped with a dual speed motor that can adjust the dimming in the same gear and a dedicated speed ratio that is not connected to the grid. It can be divided into three types: SL.s2 and S3. The fan can be equipped with a variable loss motor and a variable frequency controller to achieve zero hole speed. It is recommended to adjust the frequency half lock between 25 and 50Hz
2. Working conditions
Working cylinder temperature: -20-+80 ℃, can be continuously operated. Special: Naiyu Ge, 10D storage (can operate continuously for 20 hours):
Can run continuously for 60 minutes at 30oC:
Humidity, less than 90s%,
Quality classification: air (with a dust content not exceeding 100mg/m): Work signal: three-phase, 380N/50HZ
Dong: The condition of high culvert resistance is only used for PYHL-14 mixed type fire high exhaust phase hybrid wind turbine.
