High-pressure centrifugal fans or high-pressure centrifugal blowers operate fluidly and remove particles from the device at a 90-degree angle and perpendicular to the input axis. These devices are known as both fans and blowers, although most of them are known as blowers.
In general, it can be said that a fan is a device that is used for air conditioning, thermal movement, creating hot and cold air, or drying. However, blowers are devices that are used to move and move particles, these devices use compressed air to blow or overcome the flow resistance and place solid particles. , fans only move air, but blowers provide both air movement and high pressure.
Design of high -pressure centrifuge machine (high -pressure industrial ventilation)
Typical to medium pressure centrifuges consist of an open impeller with special grooves and blades. These grooves are located on the top of the wheel and you can see them at the entrance of the impeller. The housing part of these devices is usually very thick and the propellers are also in large sizes. These centrifuges create good pressure during their operation and are usually made of metal sheets. They are generally open and you can easily see the parts that are moving.
Efficient and durable designs of backward inclined blades to keep particles inside the chamber and on the contact area of the propellers. It is used. High pressure centrifugal fans are very narrow and their propellers are also closed except in the eye part and the circumference of the circle. These fans are very efficient and suitable for applications with high static pressures. They are made of stainless steel and strong alloys.
In suitable and efficient designs of high pressure centrifugal blowers, these devices can be opened from the middle. In fact, the housing can be disassembled and in this way clean the propellers without interfering with the input and output parts such as channels or dampers. These fans are suitable for pressures up to 20,000 pascal. Due to the high heat produced during the operation of these devices, the shafts can be cooled in order to increase their life span. These fans produce a lot of noise, but a noise reduction device can be used in them. In order not to damage these devices when they are exposed to corrosive gases, liquids and solids, strong coating materials can be used that prevent corrosion and physical damage of materials and metals.
Can high -pressure centrifuge fans be used as an air conditioner?
These fans are generally rarely known as an air conditioner or cooler, and this is because the high pressure resulting from the operation of their propeller wheels affects the environment (especially the environment around the outlet opening) ) is unfavorable for human breathing. However, if these devices are properly managed and the environment in which they are placed is large, they can be used as air conditioning devices. Of course, remember that in order not to damage these devices in high pressure and vacuum, durable and strong materials should be used to connect the channels to their inlet or outlet.
Industrial air conditioning systems in factories And such working environments are used, the pressure and other parameters must be carefully monitored and controlled.
High pressure centrifugal fans can be used in applications where the location of the fan is far from the intended environment or even in places where many spaces are to be ventilated by one fan. In these cases, the fans have to deal with various factors such as the twists and turns of channels, dampers, and the prevailing pressure in each room. With the lengthening of the channel and the development of the transverse surface, the pressure decreases continuously along the way until reaching the final destination. For such applications, customized centrifugal fans must be used to meet the requirements. High pressure centrifugal blowers are excellent for pressure testing, dust removal and solid aeration applications. Dust collectors can be connected to the outlet of a centrifugal fan and thus help them to draw air out of the room. In addition, the fan inlet can be connected to a duct that exhausts the air through a curved tube.
