Pneumatic Tube System



Pneumatic tubes on their own are not of any use to anyone. It is only when these tubes are linked together to form a pneumatic tube system that they become a convenient unit for transportation. A pneumatic tube system is made to carry different types of loads, which is why different components in the system each perform a special role or task. It is important to understand the various parts of a pneumatic tube system before you go looking to make a purchase:

Carriers: These containers are made of plastic and house the items to be transported through the pneumatic tube system. They keep the items safe from damage, especially with the addition of foam inserts to provide extra cushioning. They can be reused.

Blowers: These are big fans that, through the use of pressure, vacuum, or both, move the carriers through the pneumatic tube system.

Steel Tubes: Steel tubes are placed on the ceilings and inside the mechanical rooms. They form a network that provides speeds of about 28 kilometers per hour for transportation.

Transmission Components: This includes the tubing itself and the transfer unit. The transfer unit directs the route of the carrier from one end to the other, or vice versa. The tubing is galvanized with steel, bends, couplings, and other fittings that improve the efficiency of the pneumatic tube system.

The pneumatic tube system is in use in banks, hospitals, post offices and many other places. This means that each system is specialized for its specific purpose, and there are other parts that may be added on to achieve this purpose.
Some benefits of the pneumatic tube system include:

Cost: Steel and other materials used to make the system are widely available and inexpensive, making the overall system quite affordable.

Installation: There are not many requirements for installation, and it can be done easily to make the system ready to use.

Usage: There is no limit on the type of materials that can be transported, which means it is a system that every business can employ.

Pneumatic Tube Delivery Systems



Pneumatic tube delivery systems are used to send items from one location to another. Essentially, the system works by putting a container inside a tube that works electronically, and pushing it to the destination. There are some scientific principles involved in how this works:

Equilibrium: Pneumatic tube delivery systems involve the use of a vacuum. Gases in areas with higher pressure tend to move towards areas of lower pressure to maintain equilibrium in the system. These gases go from high concentration areas to lower concentration areas within the tube, thus pushing along any container that is held inside.

Vacuum: This can be thought of as an area in which gas is absent or in low pressure. The pneumatic tube delivery system uses this to its advantage by allowing the gas to push towards such areas, taking along the containers with it.

Pascal’s Principle: Pascal’s findings revealed that if the pressure at one point in a fluid (liquid or gas) is increased, then automatically the pressure across all the points of the fluid will increase to match the change. The pneumatic tube delivery system again uses this to ferry its contents around.

Pneumatic tube delivery systems are very flexible which allows changes to be made, such as extending or moving the tube around in case of renovation, expansion, or moving of the business itself. There is no risk of any fires or explosions in these tubes, making them safe for item transportation.
Pneumatic tube delivery systems are designed and manufactured according to the specific purpose that the user needs it for. This involves taking into account the density of the intended items to be transported. Pneumatic delivery systems are easy on the pocket and efficient at their job.

Pneumatic Tube Carriers



There are a number of pneumatic tube carriers, each built for a different purpose. The great thing about this mode of transportation is that there is no risk of damaging the items inside. Pneumatic tube carriers are utilized in several places such as hospitals, commercial businesses, etc. Here are some details about how they are used in the real world:

Pharmacy carriers: pneumatic tube carriers in pharmacies have a large holding space that can transport various pharmaceutical items and even blister pack equipment. It also comes with a latching system that provides ease of use and security of contents.

Commercial carriers: like in pharmacies, pneumatic tube carriers in commercial settings also allow for a wide range of sizes. They come in two types: side opening carriers, that open from the sides to send or receive items (such as those present in banks), and side-and-end opening carriers, that open from both the sides and the end so as to facilitate the sending and receiving of the containers.

Medical carriers: these pneumatic tube carriers are specially designed to be extra smooth, so that it is easier to glide things across them. The latching system also makes it easy to open and close the carrier. The medical carrier tubes are made airtight by using special seal strips, which are easily and cheaply available in case they need to be replaced.

Although these are the major types of pneumatic tubecarriers, each of them is manufactured according to the particular function it has to perform. Thus, pneumatic tube carriers in one business may be a bit different from the same device in another business. Examples include the pneumatic carrier, bank replacement carrier, end opening carriers, automatic system carriers, and the standard side-opening carrier.

Pneumatic tube carriers are easy and convenient to make use of. Neither do they contaminate, damage, or otherwise interfere with the contents placed in them, unlike fuel-based systems that can catch fire or explode.

Pneumatic Conveying System



In the technologically advanced world of today, the pneumatic tube system has proved to be an invaluable invention. How do they work? Compressed air is used to push small items through ducts in a tube to deliver loads to their destinations. This forms the pneumatic conveying system. There are two types of pneumatic conveying systems available: the dilute phase systems that simply push loads in one direction; and the dense phase systems that push or pull to send and receive loads in both directions.

Pneumatic conveying systems are very complex structures to manufacture, which is why there are specialized firms with advanced technology that are up for this task. Each pneumatic conveying system is made according to customized specifications. If you intend to have one built, you need to inform the manufacturer about what type of items you intend to transport, the size and source of power, the cyclone and the filter. The pneumatic air system is then produced according to the particular needs of your company. The manufacturer also includes a trolley for additional portability, should it be needed. All of these complex manufacturing techniques basically depend on the density of the items you have to ferry around.

There are numerous applications of the pneumatic conveying system:
Food industries can use it to send raw ingredients to processing plants.
Blood banks send containers of blood from the banks to the offload point.
Construction sites receive raw materials and chemicals from aluminum, cement, fertilizer industries etc. using the pneumatic conveying system.

Some other attributes to be considered are:
Safety: There is no fuel involved in the pneumatic air system, making it safe from fire or explosions, and ensuring that your valuable items are not damaged in any way.

Speed: It provides speeds of up to 25 feet per second for vertical transport and 28 kilometers per hour for horizontal movement.
Housecleaning: In large houses, cleaners can use the tubes to transport cleaning supplies and items from one room to another.

User friendly: The computer controls in the pneumatic conveying system are intuitive and easy for everyone to make use of.

Pneumatic Air Tube



A pneumatic air tube consists of a number of hollow tubes that allow for the transport of small items held in cylindrical containers. Pneumatic air tubes are powered by a flow of compressed gases passing through the tubes. The pressure that these gases create push the cylinders forwards. A pneumatic air tube can be made using simple and easily available materials including metal and wood.

A pneumatic air tube is constructed according to various specifications, such as the weight o the load it has to carry. Pneumatic air tubes are not new; they were first conceived in the 1st Century AD, providing various uses. The creative and inventive minds of today have expanded the use of pneumatic air tubes and they are implemented in a variety of industries in current times.

A pneumatic air tube is cheap to install. This is because they are made from simple and widely available materials that are mixed in specific proportions according to the principles of science. The main cost advantage of pneumatic air tubes is that they save a lot of money that would otherwise be spent on fuel for conventional transportation methods.

The main consideration to be made in a pneumatic air tube is the density of the materials. This is why there are two categories of these tubes:

CT1: This type is suitable for carrying out one-way transport that involves a number of loading and offloading points along the tube. These pneumatic air tubes only incorporate ‘push’ technology because of the one-way nature of the transport. This type of tube is especially suitable for places like a laboratory that would need to send drug samples to the nurse’s room, as well as retailers that need to transport goods to a particular safe. Cabinet stations and sleeve stations also make use of CT1 pneumatic air tubes.

CT2: This pneumatic tube can transport items in either direction simultaneously. It makes use of both ‘push’ and ‘pull’ technologies to accomplish the task of sending and receiving items from several points. This is suitable for places such as the food industry, which has a number of interdependent processes going on.
Pneumatic air tubes can be used in many other ways as well, because they are cheap and can be bought by many different types of customers. The absence of fuel in their operation means they are also environmentally friendly.
