Blower System

Blower is equipment or a tool which increases the speed of air or gas when it's passed through equipped impellers. They are mainly used for flow of air/gas required for exhausting, aspirating, cooling, ventilating, conveying etc. Blower is also commonly known as Centrifugal Fans in industry.

In a blower, the inlet pressure is low and is higher at the outlet. The kinetic energy of the blades increases the pressure of the air at the outlet. Blowers are mainly used in industries for moderate pressure requirements where the pressure is more than the fan and less than the compressor.

Blowers are the equipment that gives the transfer of air within the emitted environment at high or low and rotates the fan with the force received from the motor. Blower is the equipment that rotates the fan with the force it receives from the engine, which transfers the air within the emitted environment at high flow or low. The fan in the blowers rotates and vacuums the air in the suction section. The air is then pushed into the outlet side. Blowers are often used to move air.

TYPES OF BLOWERS

Blowers can also be classified as Centrifugal and Positive displacement blowers. Like fans, blowers use blades in various designs such as backward curved, forward curved and radial. They are mostly driven by electric motor. They can be single or multistage units and use high speed impellers to create velocity to air or other gases.

Positive displacement blowers are almost like PDP pumps, which squeezes fluid that successively increases pressure. This kind of blower is preferred over a centrifugal blower where high pressure is required in a process.

Single-Stage Blowers: Single-stage blowers are a variety of blowers ranging from 40 to 1370 in the flow range, 0-460 mbar pressures and in motor forces in the range of 0.2 to 18.5 kw. Double Stage Blowers: Double stage blowers are a variety of blowers ranging from 88-2050 flow rates, pressures ranging from 0-670 mbar and engine powers in the range of 0.7 to 25 kw.

WORKING PRINCIPLE OF BLOWERS

Inlet
Side Channel
Fan
Outlet

Blowers increase the pressure of the gas by a series formed by the centrifugal movement of the impeller. When the impeller is rotating, the channels in the impeller push the air forward by the centrifugal movement and a helical movement occurs. During this movement, the gas is continuously compressed along the channel and therefore the pressure increases linearly. The pressurized air is transferred from the outlet duct of the blower to the installation to be used.

HOW TO USE?

Eligibility of auxiliary equipment blower can prolong life.
The presence of safety valves or a system to protect the transfer will prolong the life of the blower, as blockages to the suction and discharge points may occur.
In order to avoid the accumulation of dirt and proper capacity, the air in the blower must be filtered and transferred. Failure to use filters will cause wear of the fans inside the blowers.
Blowers should not be used in the opposite direction of rotation of the motor. The life of the inverted blowers will be shorter than the air in the outlet.

APPLICATION OF BLOWERS

Blowers are used in various processes such as food, transportation, granular carrier etc. in terms of usage area. Blowers, in other words vacuum pumps are used in food washing, transport equipment powder granule conveyor, suction equipment, industrial dust extraction, paper transport, degassing, bottle filling machines, automatic filling machines, paper cutting industry, printing paper transportation process, dust removal equipment production, It is used effectively in car washing, treatment plants, jacket, bottle drying, vegetable fruit washing, heating systems.

FUNCTION OF BLOWERS

Industrial fans and blowers are machines whose primary function is to supply and accommodate an outsized flow of air or gas to varied parts of a building or other structures. This is achieved by rotating variety of blades, connected to a hub and shaft, and driven by a motor or turbine.

DIFFERENCE BETWEEN A BLOWER AND A FAN

Generally, fans are devices that move larger amounts of a gas with a very low increase in pressure. The term blower is sometimes used interchangeably with fan. In general, a blower has a slightly higher pressure rise than a fan: from 1.11 to 1.2

IS BLOWER AND A SUPERCHARGER THE SAME THING?

A “blower “is a slang term. In the traditional sense, a supercharger is mechanically driven by the engine to greatly increase the density of the air taken into the intake manifold. But typically when a person uses the term “blower”, they are referring to a belt driven supercharger.
