Pneumatic Systems and Advantages

Pneumatic Systems

A pneumatic system is a system that uses compressed air to transmit and control energy.
Pneumatic systems are used in controlling train doors, automatic production lines, mechanical clamps, etc.

The Advantages of Pneumatic Systems

Pneumatic control systems are widely used in our society, especially in the industrial sectors for the driving of automatic machines. Pneumatic systems have a lot of advantages.

(i) High effectiveness

Many factories have equipped their production lines with compressed air supplies and movable compressors. There is an unlimited supply of air in our atmosphere to produce compressed air.
Moreover, the use of compressed air is not restricted by distance, as it can easily be transported through pipes. After use, compressed air can be released directly into the atmosphere without the need of processing.

(ii) High durability and reliability

Pneumatic components are extremely durable and can not be damaged easily. Compared to electromotive components, pneumatic components are more durable and reliable.

(iii) Simple design

The designs of pneumatic components are relatively simple. They are thus more suitable for use in simple automatic control systems.

(iv) High adaptability to harsh environment

Compared to the elements of other systems, compressed air is less affected by high temperature, dust, corrosion, etc.

(v) Safety

Pneumatic systems are safer than electromotive systems because they can work in inflammable environment without causing fire or explosion. Apart from that, overloading in pneumatic system will only lead to sliding or cessation of operation. Unlike electromotive components, pneumatic
components do not burn or get overheated when overloaded.

(vi) Easy selection of speed and pressure

The speeds of rectilinear and oscillating movement of pneumatic systems are easy to adjust and subject to few limitations. The pressure and the volume of air can easily be adjusted by a pressure regulator.

(vii) Environmental friendly

The operation of pneumatic systems do not produce pollutants. The air released is also processed in special ways. Therefore, pneumatic systems can work in environments that demand high level of cleanliness. One example is the production lines of integrated circuits.

(viii) Economical

As pneumatic components are not expensive, the costs of pneumatic systems are quite low.
Moreover, as pneumatic systems are very durable, the cost of repair is significantly lower than that of other systems.

Waste of Transportation, 7 Wastes in Lean Manufacturing (SIX Sigma)

Transport is the movement of materials from one location to another, this is a waste as it adds zero value to the product. Why would your customer (or you for that matter) want to pay for an operation that adds no value? Transport adds no value to the product, you as a business are paying people to move material from one location to another, a process that only costs you money and makes nothing for you. The waste of Transport can be a very high cost to your business, you need people to operate it and equipment such as trucks or fork trucks to undertake this expensive movement of materials. Waste of transport is a consequence of excessively long, intersecting transport paths, temporary storage, load and unload, transport of pallets hither and thither. Waste of transport is also caused by too detailed process breakdown and exaggerated division of work, due to imprecisely defined intermediate warehouses and due to production in large series.  Waste of tra...

21st Century, Essay (IELTS)

The 21st century has begun. What changes do you think this new century will bring? Use examples and details in your answer. Man, through the ages, has undergone many changes from the time when he depicted a herd of mammoths on the walls of his cave to these days when he can create beautiful pictures and even make coffee by use of computer technologies without leaving his favorite chair. The 20th century made huge steps in developing computer technologies and reached many goals that made our life much easier. What should we expect in the 21st century? First of all, I think that the pace of our life will speed up: we will move faster from one place to another, from one continent to another using high speed jet airplanes. Second of all, I believe that we will be able to do many things that take much time now without leaving our house. Computers will be everywhere including out clothes. Many people will have chips and mini computers inserted in their heads to hold huge amount of ...

7 Wastes in Lean Manufacturing (SIX Sigma)

Over-Production Waste   Definition  • producing more than what is needed • producing faster than what is needed Causes • volume incentives (sales, pay, purchasing) • high capacity equipment • line imbalance; poor scheduling/shifting • poor production planning • cost accounting practices that encourage build up of inventory Over-production waste occurs when more goods are produced than can be sold, resulting in idle finished goods inventory. Over-produced goods are often hidden wastes since many think they are assets with value, when in fact most of them may be obsolete or costing the company unnecessary expenses just to keep them until they can be sold if ever. The just-in-time, pull system, and kanban rules prevent over-production wastes. Also, lean systems favor smaller equipment over large ones to avoid overproduction due to high but unnecessary capacity utilization. Processing Waste   Definition  • non-value added man processing • non-valu...
