PF150-2 High Temperature and Medium Pressure Blower - Straight Blade Blower

PF150-2 High Temperature and Medium Pressure Blower - Straight Blade BlowerCapable of functions:

1. It has dual functions of blowing and suction, and can be used for both suction and blowing;

2. Running with little or no oil, the output air is clean;

3. Exhaust and supply fans are divided into:; Pneumatic conveying and pipeline conveying;

4. Eight characteristics can be modified: (vertical, horizontal, heat-insulating, DC, explosion-proof, anti-corrosion, waterproof, belt drive);

5. The shell is die cast as a whole and uses shockproof mounting feet, so its requirements for the installation foundation are also very low. It can even operate normally without fixing the feet, which is very convenient and saves installation costs and installation cycles;

6. The fan blades that generate centrifugal force are made of double-sided forward leaning multi blade, molded in one go, with high-quality dynamic balance, extremely low vibration, stable wind force, low noise, and can withstand certain frictional impact forces, with a long service life.

7. The drainage side panel has a built-in side suction port, which, when combined with the fan blades, can generate a large negative pressure suction force, making the self-priming feeding more stable.

PF150-2 High Temperature and Medium Pressure Blower - Straight Blade BlowerWorking Principle:

1. The common medium pressure fan is a centrifugal fan, whose impeller is covered with a mechanical shell 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.

2. 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.

3. Among the performance parameters of medium pressure fans, the most important ones are gas flow rate, pressure, conveying power, efficiency, and impeller speed, which must be paid attention to during the selection process. The gas flow parameters of a medium pressure fan represent the volume of gas that the fan can process per unit time, while the pressure of a medium pressure fan refers to the internal gas pressure value during its operation.

4. The efficiency of a medium pressure fan refers to the ratio between the shaft power of the fan and the actual effective power of the processed gas. The total pressure efficiency of centrifugal fans is about 90, and in the future development of centrifugal fans, efficiency values will be one of the goals that researchers further pursue.

It is one of the popular types of fans in the fan market; People only know the utility and function of medium pressure fans, but they do not know the essence of medium pressure fans?

During the operation of the fan, the airflow enters the blade space from the axial direction of the fan, and then rotates with the impeller under its drive; On the other hand, a fan that increases energy under the action of inertial force, leaves the impeller in the radial direction, and relies on the centrifugal force generated to do work is called a medium pressure fan.A medium pressure fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate gas, then decelerate and change the flow direction, converting kinetic energy into potential energy (pressure). In a single-stage centrifugal fan, gas enters the impeller from the axial direction, changes to the radial direction as it flows through the impeller, and then enters the diffuser. In a diffuser, the gas changes its flow direction causing deceleration, which converts kinetic energy into pressure energy. The increase in pressure mainly occurs in the impeller, followed by the expansion process. In multi-stage medium pressure fans, a reflux device is used to direct the airflow into the next impeller, generating higher pressure.Medium pressure fans are commonly used auxiliary production equipment in stone processing enterprises, mainly used in ventilation and dust removal devices. For example, centrifugal fans are required for dust removal in stone cutting and polishing processes, such as cyclone dust collectors and bag dust collectors, to ensure a clean production environment and protect the physical and mental health of producers.The medium pressure fan is essentially a variable flow and constant pressure device. When the speed is constant, the theoretical pressure flow curve of the medium pressure fan should be a straight line. Due to internal losses, the actual characteristic curve is curved. The pressure generated in the medium pressure fan is greatly affected by changes in intake temperature or density. For a given intake volume, the pressure generated at higher intake temperatures (lower air density) is lower. For a given pressure and flow characteristic curve, there is a power and flow characteristic curve. When the blower operates at a constant speed, the required power increases with a decrease in intake temperature for a given flow rate.
