For industrial and laboratory purposes, is frequently used equipment, which is based on the energy of the vacuum. Vacuum is a compressed gas under a pressure below atmospheric. Artificially forming the vacuum space, it is possible to bring the substrate in movement, to adjust the speed, use kinetic energy.
Scope
Vacuum equipment used in everyday life and many industrial sectors:
the-
the
- in the electronics; the
- industry; the
- mechanical engineering; the
- military industry; the
- aircraft; the
- space; the
- food industry; the
- chemical;
mining.
Vacuum technology allows to ensure the operation of mechanisms without additional sources of supply or to reduce energy consumption. Prized for such qualities as:
the-
the
- environmentally friendly; the
- high performance the
- safety; the
- lowest cost; the
- universality; the
- simplified maintenance and repair.
Vozduhonosnye machine
One of the varieties of equipment working on the basis of vacuum systems, vozduhonosnye machine. They perform the following functions:
the-
the
- air supply; the
- transportation of non-combustible gas through the pipeline; the
- transportation of bulk materials; the
- rarefied air.
Used to provide some vehicles, help to create an air cushion. Need for aeration of the ponds, space heating with a large area. Also used for cleaning in textile mills. Very vary greatly in features, size, working principle and many other parameters. The only constant is what is used vacuum to obtain the kinetic energy, security mechanism.
This equipment in power is intermediate between the compressors and fans. So the compressors on the average can create excessive pressure from 100 kPa to 400 kPa, the fan is from 0.5 kPa to 10 kPa, and blowers from 10 kPa to 200 kPa.
a Little history
the First blower was collected in 1766. It was used in Barnaul foundry to ensure the operation of the bellows of blast furnaces. A few people required to manage the process. Today devices are used offline. They are equipped with insulation to make their work did not cause harm to the person. Work is continuing to study optimization of operating parameters, improve efficiency, to simplify installation and connections, provide new industries with high-quality equipment.
Types of blowers and gas blowers
the Basic varieties of blowers.
-
the
- two-rotor. They are compact and powerful, the most popular type. Two rotor rotation increase the kinetic energy created by the vacuum, guaranteeing a fast flow of air or gas from the pipeline to the internal drive to create the pressure difference. The bandwidth is variable, determined by the manufacturer. Can be from 1m3 up to 400 m3. The created pressure differential from 10 to 100 kPa. the
- Turbine. During the rotation of the turbine provides compressed air and gas to drive its movement to the periphery. These blowers are less compact, but they have significant bandwidth and power. They can handle from 60m3 to 500m3 gas for 1 minute. Centrifugal and vortex also belong to this class of blowers. They have less bandwidth from 3M3< / span> up to 300m3< / span> per minute. The pressure drop from 8 to 80 kPa. the
- Piston. The pressure difference creates a reciprocating movement of the piston. This configuration is today considered the least effective. Rare to find in selling such a device. Double rotor and turbine blower is able to replace them.
Rules of operation
Vozduhonosnye machines and vacuum equipment type reliable. By purchasing it, you can expect to reduce the cost of electricity, more expensive technologies, without compromising the quality of production processes. But, like any equipment, they need maintenance, preventive measures, repair and rehabilitation works. It is recommended to consult specialists in the field of vacuum equipment. It's a guarantee that any unit will work perfectly without requiring frequent attention.
