Overview

The selection of vortex duct fans is widely used in industries such as paper cutting machines, combustion oxygen reduction machines, cigarette filter forming machines, electroplating tank mixing, atomization drying machines, water treatment aeration, aquaculture, screen printing machines, photographic plate making machines, injection molding machines, automatic feeding drying machines, liquid filling machines, powder filling machines, welding equipment, film machinery, paper transportation, dry cleaning of clothes, cleaning purposes, air dust removal, dry bottles, gas transmission, feeding, collection, environmental water treatment, central dust collection environmental protection, aquaculture, screen printing, electroplating, dust removal, food, packaging, filling, glass products, airflow transportation, etc.

Product Details

Selection of vortex duct fanWorking principle of vortex duct fan: High pressure fan is a dual-purpose vortex air pump for blowing and suction. The special blade design of high-pressure fan has the characteristics of high pressure, large air volume, low noise, and high temperature resistance. The high-pressure fan has strong insulation performance, easy installation, high stability, and the gas passing through is oil-free, dry, and of the highest quality. The generation of high pressure and high suction is due to the design of the impeller. The impeller edge of a high-pressure fan has multiple blades. When the impeller rotates, due to centrifugal force, the air in the two blades is quickly moved towards the outer edge, transferring energy and causing the wind pressure to quickly stack, resulting in high pressure or force and an increase in speed. When the air is reintroduced into the impeller by the air duct, it will be accelerated again. Due to the multiple blades of the high-pressure fan transmitting energy, the wind pressure is rapidly superimposed, forming high pressure or high suction force

Selection of vortex duct fanmatter

1. Need to determine what function of the high-pressure fan is used on site, whether it is suction or blowing, and find the corresponding pressure flow curve of the high-pressure fan; If the curve is misread, sometimes the selected product cannot be used;

2. Based on the calculated pressure and flow rate, find the working curve above the corresponding working point that satisfies both pressure and flow rates on the curve graph; Then select the high-pressure fan model based on the working curve;

As long as it is a different work site, its requirements for pressure and flow rate are different, so in order to obtain relatively accurate data, relevant calculations need to be carried out.

Precautions
No matter which brand of high-pressure fan it is, two aspects of protection are needed: pressure and dust.
For pressure, a pressure relief valve is often used, which is an unloading valve. When the operating pressure of the high-pressure fan exceeds the set pressure of the pressure relief valve, the pressure relief valve will automatically open to release the excess pressure and protect the high-pressure fan.
For dust, filters are often used. It often uses filter cartridges with different filtration accuracies according to different usage scenarios. Different filter cartridges have different maintenance methods and service lives, which need to be clarified when ordering.
In some special occasions, special protection is also necessary: for example, when using in a sealed environment, attention should be paid to ventilation and heat dissipation; When the ambient temperature (intake temperature is relatively high), it is more important to pay attention to ventilation and heat dissipation, or choose a vortex fan that allows for a higher intake temperature. For some brands of high-pressure fans, there may be their own usage suggestions. Before purchasing, it is necessary to have a detailed understanding.
