Diagonal flow fan It is a common ventilation equipment in the market. It is a new ventilator between the axial flow fan and centrifugal fan. The advanced CAD software is adopted. The multi-purpose optimization design of the new high-tech ventilation ventilation product is designed by the oblique flow meridian acceleration method. The wind pressure is higher than the axial flow fan with the same number, and the air volume is larger than that of the centrifugal fan with the same number. It has the advantages of high efficiency and high efficiency. It is characterized by low noise, compact structure, easy installation and low price. It is mainly composed of impeller, casing, inlet collector, outlet deflector, motor and so on. The shell is connected by a cylinder and divided into three segments, and the outlet is connected with the air pipe. The inlet collector is made into a sword collecting streamline, and the overall structure is composed of a sound absorbing net plate. The outlet is equipped with a deflector so that the outlet air flow has good airflow distribution and stable pressure.
The diagonal flow fan can be used as general ventilation. The conditions of use are as follows:
1. place of application: indoor ventilation for general factories and buildings, which can be used as both input gas and exhaust gas.
2. the types of gas transported: air and other unnatural, harmless to the human body, non corrosive gases to steel.
3. impurities in the gas: no viscous material is allowed in the gas, and the dust and hard particles contained in the gas are not greater than 150mg/m3.
4. according to the special needs of users, we can also design a magnetic motor drive to realize the structure of variable speed and variable air volume.
5. gas temperature: no more than 80oC.
Basic maintenance of diagonal flow fan
1, the use of the environment should be kept clean and tidy, the surface of the fan is kept clean, and the inlet and outlet shall not have sundries, and regularly remove dust and other debris in the fan and pipes.
2, can only be operated under the normal condition of the fan. The colleagues must ensure that the power supply facilities are adequate, the voltage is stable, and the operation is strictly prohibited. The power supply lines must be private lines, and the temporary lines should not be used for long time.
3. During the operation of the fan, it is found that the fan has abnormal sound, the motor is seriously heated, the shell is electrified, the switch is tripped, and it can not start. In order to ensure safety, it is not allowed to carry out maintenance in the operation of the fan. After maintenance, it should be tested for five minutes or so.
4, according to the use of environmental conditions, it is necessary to add or replace grease to bearings at irregular intervals (motor bearings are not necessary to replace grease) during the service life. In order to ensure good lubrication in the running process of the fans, the number of refueling times is not less than 1000 hours / times closed bearings and motor bearings. The 2/3. of the zl-3 lithium grease filled inner and outer rings of the bearings is strictly prohibited.
5. Diagonal flow fan It should be stored in a dry environment to avoid damp. When the fan is stored in the open air, there should be some defensive measures. During storage and handling, the blower should be prevented from bumping, so as not to damage the fan.
