Do you know the side channel blower? With the continuous development of industry, there is an increasing demand for blowers in industrial production. In many industries, such as sewage treatment in factories, leather cutting, etc., there are blowers. And this phenomenon has a tendency to continue to develop. The side channel blower is one of them, so knowing the side channel blower will be very helpful.

This article contains the following:

  • Scope of application

  • Working principle

  • Precautions for use

  • Conclusion


1. Scope of application

The side channel blower is suitable for the negative pressure pneumatic conveying system (also called the negative pressure air conveying system). The vacuum generated by the side channel air blower (or the side channel air pump) sucks the bulk granular material with the negative pressure airflow. It is sent to the designated container (silo), and the vacuum suction type pneumatic conveying device is a core negative pressure collecting system, which is especially suitable for systems with short distance, high material temperature and multi-point discharging.

In addition to this, there are also the following applications: industrial vacuum cleaners, paper cutters, cigarette filter molding machines, plating tank agitation, atomization dryers, water treatment aeration, screen printing machines, photo platesetters, injection molding machines. Materials, dryers, liquid filling machines, electric welding equipment, film machinery, paper transportation, dry cleaning clothes, cleaning, air dust removal, dry bottles, gas transmission, feeding, aquaculture, wastewater treatment, aeration and gas explosion, industrial vacuuming , photoengraving, powder and granule transport, construction site and other aspects.


2. Working principle

The impeller is mounted directly on the rotor of the motor and is completely contactless. Since the pump shaft is mounted outside the compression chamber, the maximum operating reliability of the machine is ensured even when operating at the maximum differential pressure.

The gas is drawn in by the suction port, and when it enters the side passage, the rotary impeller gives the gas a speed in the direction of rotation. At the same time, the centrifugal force on the blades causes the gas to accelerate outward and the pressure to increase. As the rotation progresses, the kinetic energy of the gas increases, causing the gas pressure along the side channels to further increase. As the side channels narrow at the outlet, the gas is forced out of the vanes and exits the pump body through the outlet muffler.


3. Precautions for use

1) Maintenance and maintenance of the blower operation process

When the side channel blower is running, the equipment running status should be checked and recorded every hour. If there is a big difference with the previous record, the cause of the difference should be analyzed in time and appropriate measures should be taken to eliminate it. In particular, pay attention to the timing of equipment running stability, bearing housing oil seal, and bearing temperature. 


2) To ensure a clean use environment, control the ambient temperature during the use of the blower

Due to the small blower clearance, dust and sludge tend to adhere to the impeller after a long period of operation, so that the friction between the impellers is greatly increased. This situation not only causes damage to the impeller, but also reduces the gap between the gears again. An increase in the friction between the impellers causes a large noise. Therefore, it must be ensured that the air medium is transported at a dust content of 100 mg / m 3 . At the same time, it is also important to periodically replace the filter cloth at the blower inlet.


 4. Conclusion

As mentioned above, the so-called side channel blower is also only one form of blower, and the side channel blower has the advantage of high work efficiency. At the same time, it should be noted that when using the side channel blower, it is necessary to pay attention to the above. After all, the service life and use efficiency of the machine depend on the user's operation mode.
