TB blower composting fermentation permeable fan explosion-proof medium pressure fanMany conveying industry fans often contain a certain amount of homogeneous particles of different sizes and shapes in their working medium, such as induced draft fans in dust removal systems and blowers in pneumatic conveying. Due to the fact that these fans operate in dusty airflow, the dust particles in the airflow not only cause wear and tear on the fans, but also accumulate dust on the fan blades, and this wear and dust accumulation are uneven. As a result, the balance of the fan rotor is disrupted, causing fan vibration, shortening fan life, and in severe cases, the fan may not function properly. Especially the wear and tear of fan blades is severe, which not only destroys the flow characteristics inside the fan, but also easily leads to accidents such as blade breakage.

Medium pressure fan for boiler equipmentThe impeller of a medium pressure fan (also known as a centrifugal fan) is covered with a mechanical casing, and the center of the impeller is the air inlet. When the medium pressure fan is working, the power equipment drives the impeller to rotate, drawing air in from the air inlet. During the rotation of the blades of a centrifugal fan, a dynamic force is applied to the gas, increasing its pressure and velocity. The gas is discharged from the exhaust port along the blade path under the action of centrifugal force.

During the operation of a medium pressure fan, although the rotation of the impeller increases the pressure and velocity of the gas, the various changes in the gas are relatively small. Therefore, in the design and use of centrifugal fans, gas is usually treated as an incompressible fluid. The gas treatment process of medium pressure fans is completed in the same radial plane, so medium pressure fans are also called radial centrifugal fans.

Usage and maintenance:

1. The fan should be placed in a relatively stable place, and the surrounding environment should be clean, dry, and well ventilated.

2. The direction of rotation of the fan impeller must be in the direction indicated by the arrow on the fan casing.

3. When the fan is working, it should be avoided that the inlet and outlet of the fan are sealed to prevent excessive heat generated by the air pump and damage to the air pump caused by motor overcurrent.

4. Except for the two bearings of the motor rotor, there is no direct contact friction in other parts of the fan. The installation method of bearings for this air pump is mainly divided into two categories. The bearing at the end of the class air pump is installed in the pump body between the motor base and the impeller, and this type of air pump does not need to be lubricated normally. The bearings on the second type of air pump end are installed in the middle of the pump cover, and the bearings on this type of air pump end should be regularly lubricated with grease (7018 high-speed grease). Once a month, for air pumps that work continuously in three shifts, the refueling frequency should be increased. The maintenance and upkeep of the bearings on the motor and fan end of this type of air pump are classified according to the type of air pump.

5. The filter screens and silencers at both ends of the inlet and outlet should be cleaned in a timely manner according to the situation to avoid blockage and affect use.

6. The external connection of the inlet and outlet must be made using flexible hoses (such as rubber hoses or plastic spring hoses).

7. Bearing replacement: Bearing replacement must be carried out by personnel familiar with repair work. First loosen the screws on the pump cover, and then disassemble the parts one by one according to the order shown in the diagram. The disassembled parts should be cleaned, and then assembled in reverse order. When disassembling, do not forcefully pry the impeller, use a roller to remove it, and do not miss the adjusting gasket to avoid affecting the clearance that has been adjusted before leaving the factory.

8. It is strictly prohibited for solids, liquids, and corrosive gases to enter the pump body.

Transparent medium pressure fanInstallation precautions:
1. Installation location: It must be installed indoors in a place that is not affected by wind and rain
2. Environmental temperature: below 40 ℃
3. Relative humidity: below 80%
4. Air quality: If there are corrosive or flammable gases such as acids and alkalis in the air, they should not be transported by high-pressure blowers to avoid danger
5. Dust protection: Avoid using in places with large amounts of dust, powder, or fibers. If it is necessary to use in such places, please install a filter and regularly clean the dust attached to the filter and inside the high-pressure blower
6. Ventilation and heat dissipation: Please choose to use it in a well ventilated place and not in a sealed room or box
7. Placement space: For the convenience of column maintenance or repair, please avoid installing in overly narrow locations
8. Avoid vibration: Please install in a vibration free location; If the vibration in the venue is unavoidable, anti vibration measures must be installed to prevent the high-pressure blower from being damaged by external vibrations.

medium pressure fanStructural characteristics:

1. The medium pressure high-temperature resistant fan is mainly composed of impeller, casing, air inlet, motor, connector, cooling fan blades, and other parts.

2. The impeller adopts a multi blade single inlet centrifugal impeller, made of high-quality galvanized or cold-rolled steel plate, and the blades are designed based on aerodynamic principles. The impeller consists of 10 aft tilting airfoil blades, a curved front plate, and a flat rear plate. The material is made of high-quality steel plates with high strength and durability, and undergoes strict dynamic and static balance correction. Good air performance, high efficiency, and smooth operation.

3. The air inlet adopts a convergent streamlined vortex reduction form, which reduces airflow loss and improves the working efficiency of the high-temperature fan.

4. The casing of the medium voltage and high temperature resistant fan is connected to the motor through metal casting installation. The motor shaft head is equipped with a heat dissipation fan blade, and the outer wall of the metal casting is provided with inlet and outlet pipe interfaces to cool down the metal casting and shaft head, ensuring the normal operation of the motor at high temperatures.

5. The motor adopts a special high-temperature motor, and the fluid part of the high-temperature resistant fan is made of heat-resistant materials, with reliable cooling structure performance. Compared to other boiler induced draft fans, it has the advantages of simple structure, easy maintenance, and high cost-effectiveness.
