Backward Centrifugal Fan For High Pressure Forced Ventilation And Non-Viscous

9-26 high pressure centrifugal fan is generally used for forging furnace and high pressure forced ventilation, and can be widely used for conveying materials and conveying air and non-corrosive, non-spontaneous combustion, non-viscous substances of gas. The temperature of the medium is generally not more than 50 ° C (the highest is not more than 80 ° C), and the dust and hard particles contained in the medium are not more than 150mg/m3. The high-pressure centrifugal fan needs attention in the installation, and it should be operated according to the instructions to avoid errors. The following installation steps of 9-26 high-pressure centrifugal fan are introduced by Rongsheng Ventilation Company and everyone:

1. Before installation, the components of 9-26 type high-pressure centrifugal fan should be comprehensively inspected, whether the rotation direction of the impeller and the casing is consistent, whether the connection of each part is firm, and whether there is any friction after the impeller rotation. If the problem is found, it should be adjusted immediately.
2. During the installation of 9-26 type high-pressure centrifugal fan, pay attention to check that no tools and debris should be left in the shell. The connection of the inlet and outlet air pipes should be naturally consistent, and no forced connection should be allowed.
3. For the coupling or fan with transmission, check whether the coupling or belt wheel and belt are installed reliably. Whether the position of the two pullies is on a Central Line, and whether the concentricity of the fan shaft and the motor shaft meets the technical requirements (radial displacement 0.1mm, inclination 0.8/1000).
4. 9-26 type high pressure centrifugal fan installed, test run, can be in the fan starts must in no load adjustment door shut down the wind coming into the wind to adjust slightly open under the situation of induced draft fan for boiler (especially or high temperature fan), should be closely following the current in the boot process, shall not exceed the current rating, as well, gradually open the gate to the point.
5. When the 9-26 type high-pressure centrifugal fan reaches the normal speed after starting, it should be checked whether the bearing temperature is normal (generally not higher than 80 ° C). If the fan is found to have severe vibration, the bearing temperature rises rapidly and abnormal sound and other abnormal phenomena, it must be urgently stopped for inspection.

Ronsheng manufacturer introduces 9-26 type high pressure centrifugal fan maintenance matters needing attention:

• Only the high-pressure centrifugal fan can operate under the condition that the equipment is completely normal.
• If the fan equipment is started after maintenance, it is necessary to pay attention to whether each part of the fan is normal.
• Regularly remove dust, dirt and other impurities inside the fan, and prevent rust.
• In order to ensure personal safety, the maintenance of the fan must be carried out during parking.

2, 9-26 type high pressure centrifugal fan normal operation matters needing attention:

1. In the process of starting, stopping or running the high-pressure centrifugal fan, if abnormal phenomena are found, they should be checked immediately. If there is a small fault, the cause should be identified in time and the cause should be eliminated. If a major fault is found, stop immediately for maintenance.
2. In addition to the lubricant should be replaced after each maintenance, the lubricant should be replaced according to the actual situation under normal circumstances.
