Industrial blowers made in Russia

Industrial blowers are multifunctional devices that allow you to create excess pressure (0.1-1 atm) or vacuum (up to 0.5). Usually this is a large-scale equipment with a complex design.

Such devices are capable of operating for a long time at maximum loads. Industrial units are able to function under water and in adverse conditions.

Applications

Most blowers are versatile devices that are capable of pumping and creating a vacuum.

The main areas of use for industrial blowers are:

  • For aeration of water bodies... Due to aeration, the water is saturated with air or oxygen. In water treatment systems, this allows you to remove manganese, iron and various volatile substances from the water. The result is improved water quality. In fisheries, oxygen saturation of water contributes to the development of fish and other inhabitants of artificial reservoirs.
  • Bulk material transportation... Equipment designed for the rapid movement of bulk components is called pneumatic conveying. This operation is carried out by vortex devices capable of creating a dense air flow. Pneumatic conveying with a blower is easy to use, quick to install, quiet and does not require additional air drying or cooling systems.
  • Maintaining combustion... Combustion is maintained using industrial equipment, which is necessary for roasting and drying kilns.
  • Drying of films and surfaces covered with varnishes or paints. The air flow generated by the blower is used to dry the film. First you need to develop it, after which the required amount of solution is removed by blowing. Then, under the influence of vacuum, the film is dried.
  • Vacuum related industries... Blowers are actively used in the production of castings by the vacuum method, packaging, and gas sampling.
  • Ventilation, dust and dirt removal... The device can be used as an industrial vacuum cleaner to remove various contaminants. Blowers are used to remove material residues from conveyor belts, weaving and other machines.

Main varieties

Depending on the design, there are several types of industrial blowers. They differ in noise and vibration levels, performance, and engine type. The choice of a device depends on the area in which you plan to use it and its performance.

Piston blowers

In piston blowers, a large volume of air is captured, which is forced by the forward movement of the piston. Their main advantage is the creation high working pressure.

Piston blowers are distinguished by their low cost, high efficiency and versatility. Installations are subdivided into dry and oil installations. Dry ones have a shorter life span, give out clean air and are suitable for occasional use.

This type of equipment is considered obsolete and is being replaced by more efficient devices.

Screw blowers

A device of this type contains rotors equipped with blades of complex shapes. As they rotate, the air is compressed and then directed through the hole. In the working cavity of such a system, there is an oil mixture that reduces friction.

The advantages of screw units are:

  • low vibrations and noise level;
  • no need to prepare the foundation for their installation;
  • clean produced air;
  • the presence of an automatic control system.

The disadvantages of this equipment include the complexity of the mechanism, high oil consumption at increased loads and the high cost of the screw block.

Twin rotor blowers

If it is necessary to obtain high pressure, two-rotor gas blowers are chosen. Their working cavity has two rotors that rotate synchronously.

These are practical devices that have the following advantages:

  • low noise and vibration;
  • long service life;
  • simple construction.

The disadvantage of such devices is their low energy consumption. Another negative factor is the pulsation of the air flow, which creates increased vibrations. The result is increased wear on the mechanism.

This effect can be reduced by means of shock-absorbing cushions and a casing with sound insulating properties.

Centrifugal blowers

These devices are a radial type dynamic compressor. The movement of the air flow in them occurs in the perpendicular direction to the axis of rotation.

The advantages of centrifugal blowers are:

  • high performance;
  • work in continuous mode;
  • low noise level;
  • safety due to the lack of interaction between gas and oil;
  • compactness;
  • the convenience of use.

Their disadvantages include the need for lubrication and additional cooling.

Submersible blowers

The submersible device is designed for installation at the bottom of water bodies. Water provides cooling to the case, which increases the life of the mechanism. The submersible equipment is silent and fully automated.

Turbo blowers

Turbo blowers are used for high compressed air consumption. Their principle of operation is similar to that of centrifugal devices. Air is pumped under the action of centrifugal force, which is provided by the rotation of the impeller.

Turbo blowers are subdivided into single-stage (create a head above 3, but not more than 6 m) and multi-stage (head up to 30 m). Such devices are suitable for aeration, transport of substances, creating air curtains, drying containers and removing moisture from surfaces before final coating.

Vortex blowers

Vortex-type devices have side channels in which there is a repeated impact on the gas through the impeller. The result is increased kinetic energy and high pressure.

Vortex equipment operates almost silently, is compact in size and highly reliable. During its operation, there are no vibrations and pulsations of air flows.

According to the KDP, such devices are inferior to centrifugal models. Another disadvantage is the need to use a filter, since the ingress of foreign objects can damage the device.

Electric blowers

In electrical units, air is supplied by the operation of an electric motor. Such equipment is less expensive than mechanical devices.

Important! These blowers consume more electricity, but have a higher performance.

Criterias of choice

The main requirement for an industrial blower is compressed air demand. There is no need for a large stock here, since backup equipment is used in emergency situations.

Important! When choosing a blower, the maximum pressure drop is taken into account.

Depending on the purpose of the device, you need to pay attention to the following nuances:

  • air flow quality (requirements for dryness, absence of foreign particles);
  • functioning in vacuum mode;
  • features of service, its cost and simplicity (this expense item should be less than 1% of the cost of the device);
  • noise level, especially if the equipment operates near a residential area.
