Business Analytics Helping Businesses To Grow

Business analytics provides solutions which help to make strategic decision by collecting large amount of data. You would find that it does have not simple but complex data like profits, losses, transactions, marketing return, customer feedback etc. Usually business analytical software is used to generate these types of data. This is not a new term, though it has become more accurate and structured with time. People often need a proper structure to evaluate the huge amount of information and data available.

Business analytics helps you to get a deeper and better insight of any business by breaking down complex data. Apart from providing valuable insights, it also cut unnecessary costs, identifies areas to improvement and offers quality service to customers. By analysing the expectation and needs of customers, it offers solutions for you to fulfil these areas.

You would find business analytics to be closely related to competitor analysis and customer analytics. By building strategies, it helps to provides upper hand to you over your competitors. Information is supposed to be treated as an asset by organizations which ultimately lead to applying prescriptive, predictive and descriptive analytics. Nowadays, it has become even more crucial because business organizations are worried more about survival rather than profits.

By using a business analytical software people can use results in the best way by analysing information and gathering essential data. People are able to make highly focused and accurate decisions to help their business to succeed. They can make most out of their analysed and collected data. This type of software conducts effective data mining, enabling the collected information to be accurately put into different business models. It can be used in multiple tasks like various drafting strategies which can optimize and utilize marketing data.

Business analytics is quite crucial component helping to improve operational performance as organisations are supposed to deal with huge amount of data. Even small businesses with the help of analytics models can disparate data or use information to its full potential. Future trends of a business are predicted as these models generate trends and patterns using historical data

When a fan is installed in a high temperature

Bearings usually require high temperature lubricants and sometimes circulating oil or static oil in a monoblock. Bearings can be kept cool in high temperature applications by using a shaft cooler and a shaft seal. For higher temperature fans, water cooling can be used to cool the shaft. In this case, the fan should be belt driven in order to install a rotating union to circulate the water over the shaft. Bearings should be kept out of a high temperature airstream and should never run in air temperatures hotter than 130F. The inboard bearing, which is the bearing nearest the fan housing, should be moved away from the fan housing to create some space for the heat to dissipate. The space created between the inboard bearing and the fan housing allows for the use of a shaft cooler and shaft seal. Bearing temperatures should be monitored and should not be allowed to exceed 200F at speeds higher than 2500 RPM and 220F at speeds below 2500 RPM. Bearings should be selected to allow for free movement of the shaft lengthwise due to temperature changes. One bearing should be fixed, serving as an anchor bearing to locate the shaft lengthwise. The bearing closest to the drive end is normally fixed. All other bearings should be expansion bearings to permit the shaft to move lengthwise. The thermal growth of the shaft may limit the bearing used.

A shaft cooler is a small fan that clamps on the shaft between the fan housing and the inboard bearing. The shaft cooler draws cool air over the shaft and bearings as the shaft rotates to dissipate the heat. A shaft cooler is recommended for all applications over 300F. Generally, the pedestal must be modified to allow room for the shaft cooler. This will increase the distance between the inboard bearing and the wheel. This dimension, referred to as the overhang dimension, is critical in determining the safe speed of the shaft. As the overhang dimension is increased, the shaft safe speed becomes lower. During maintenance repairs, it is very important that the overhang dimension is never increased. When the temperature exceeds 800F, it is necessary to separate the fan pedestal from the fan housing. By doing this, the amount of heat conducted through the pedestal and to the bearings and motor is greatly reduced.

For housing material, carbon steels are satisfactory for temperatures up to 800F and Corten is often used for temperatures up to 1000F. For higher temperatures, stainless steels and Inconel may be required. A customer may want to keep the heat of the airstream from heating up the fan housing and radiating out to the surrounding area. Insulating the fan accomplishes this. There a few ways to insulate a fan, but the main idea is to create a second fan housing offset from the main fan housing and then fill the gap between the two with insulation. It is common to have 2″ – 6″ of insulation depending on the temperature of the airstream and the need for the outer skin to be cool. For fans that require an access door and also have an insulated housing, the access door is raised from the fan housing to the outer insulation skin by building a box between the two housings.

Special Information About Mechanical Drawing

The machinist should have a drawing from which he is able to obtain accurate information, which enables him to take the actual rough casting and through slotting, planing, drilling, milling, chipping or turning, they produce the finished fixture as conceptualized by the drafter.

Contractors, architects, and engineersof all kinds must have accurate drawings for them to produce satisfactory results within their particular fields. To accomplish this feat, it is necessary that working drawings are be created according to particular principles and methods thoroughly understood by the one who makes the drawing and the one who uses it.

The structural engineering drawings serve as the common language for just about all mechanics and machinists. Through implementing it, the ideas from the designer, architect or engineer are transmitted or conveyed to the worker. There is hardly any area of work in industry in which the knowledge of drawings are not utilized universally. It is certainly true that there is no industry that doesnot require knowledge of drawing and the employment of drafter. Examplesof machines and fittings, with the aid of mechanical drawings and working sketches, is the necessary first step in building these machines and fixtures.

If we then consider mechanical drawing like a language, we understand then that they are to be used to share thoughts and ideas. Orthographic projection, the industry division of descriptive geometry, is its grammar and also the foundation upon which is built a myriad of correct mechanical drawings. It is actually the art of symbolizing any object so accurately that the skilled worker, upon checking the drawing, should have the ability to make the object precisely to the materials and dimensions provided, without any further spoken or written instructions by the designer.

The objects illustrated could be machines, implements, buildings, items, or ornaments. They may be constructed of many numerous materials. The drawings might be linear, shaded and colored, or plain. Because of the nature of the information being conveyed, they must be precisely scaled, but various geometrical methods might be employed.

Fiberglass Fan For Chemical Industry

Chemicals industry provides the widest range of challenges for rotating equipment. CB Blower Co. fans and blowers operate in conditions encompassing extreme pressure and temperature, and handle a wide range of gases containing aggressive and toxic components. Demanding specifications and strict safety requirements must be met and above all is the need for dependable operation over long periods.

CB Blower Co. fans meet the challenge of moving gases continually, reliably, efficiently and safely. They are built to API, or equivalent industry standards and their performance has been proven over many years of operation; and the blowers can meet unusual requirements that include dual drive systems with automatic drive engagement / disengagement and special materials of construction.

CB Blower Co. fans and pressure blowers are found in all major process plants. The range of applications is very wide but includes:

� custom engineered centrifugal process fans for combustion air supply. These may be used directly for fired heaters for ethane or naphtha cracking plant and for processes with steam reforming such as methanol, or for boilers serving general utilities. Flue gas extraction and tail gas clean up are among the other applications for which we have supplied custom fans.
� auxiliary boiler and other pre-engineered fans.
� cooling fans for mechanical draught cooling towers, air-cooled heat exchangers and air-cooled condensers.
� turbo blowers for sulphur recovery combustion and reaction air, sulphuric acid and carbon black plant
� screw type pressure blower systems for process gas handling, notably for butadiene plants, gas turbine gas fuel compression and process refrigeration.
� reciprocating turbo blowers for hydrogen processes – hydrocracking, visbreaking, catalytic reforming

The demands placed on equipment in the chemical industry are particularly high. Toxic, corrosive and unstable gases are frequently a part of chemical production processes. Maintaining the purity of gases being handled is a priority in the pharmaceutical and biological industries. CB Blower Co. supply a range of fan / blower types to the chemical industry, from fans for boiler and incineration plants that supply heat and process steam, to fans that are used on exhaust and emissions control systems to equipment that handles the materials being processed. In such a diverse industry the range of applications is very wide but there is often the need for special materials to prevent corrosion by gases such as wet hydrogen chloride and hydrogen sulphide. The blowers are adapted to meet these special needs.

New Methods Of Ventilation

A common problem in the average plant is “air starvation”. Exhaust systems throughout the structure may have been well designed for their intended purpose. However, no consideration may have been given to the replacement of exhaust air. As a result, the building may be under severe negative pressure. This situation reduces the efficiency of the exhaust fans and produces unhealthy and uncomfortable working conditions. Substantial economy and efficiency can be obtained by correcting this situation through the use of supply fans or “make-up air” units. Many buildings have adequate exhaust and supply fans to provide a comfortable environment for the occupants. Unfortunately, there may be little control over the distribution of the air to produce the desired results. Good planning will recognize the necessity for proper air distribution and circulation through the occupied areas of the building. Suitable deflectors and baffles can be incorporated where needed. “Booster fans” or air circulators can be positioned to take care of trouble spots and augment the direction and velocity of the air flow. Diffusers may be required lo assist in air distribution. Drafts and dead spots can thus be eliminated. All of these are inexpensive aids that can ensure that a well planned system will achieve its important objectives.

Exhaust fans are usually located near the area where heat-producing machinery is found in the industrial building. This has the very practical advantage of exhausting this superheated air near its source and preventing a heat build-up in other areas. If side wall locations are to be utilized for air intake or exhaust, it is desirable to consider the prevailing wind direction during the summer season. If the ventilation system can be oriented to take advantage of prevailing winds, the efficiency of the system may be increased considerably, Systems that incorporate roof exhausters are usually not affected by a prevailing wind.

Where air velocity is the critical factor in a breeze conditioning system, use of the “long dimension” of the building or room is highly desirable. By moving air through the long dimension, the cross-sectional area is reduced and less air volume is required to obtain the needed air velocity. A vital element in the successful breeze conditioning system is a supply of clean, cooler, fresh air. While such an ideal air supply may not be available, common sense dictates that air being supplied into the building should be from the best available source. Avoid recirculating air that has just been exhausted from the building or another nearby structure.

The noise level in most commercial and industrial buildings has become a highly critical matter. Although the ventilating equipment is only one item in the overall total, its effect should be carefully considered. If the normal noise level in the building is low, the noise level of the ventilating equipment should be low; if the background noise level is high, the amount of noise added by the ventilation system may be insignificant

High Temperature Industrial Fan

For industrial fans applications, it is necessary to consider high cycle fatigue, low cycle fatigue in cyclical operation with speed changes, and numerous start-stop cycles. If rapid temperature changes are encountered, transient analysis may be required due to thermal stresses. When fans are exposed to elevated temperatures, many aspects of the fan design must be reviewed to make sure the fan will withstand the extreme temperatures and that the fan is appropriately designed for the application. Depending on the exposed temperature levels, the following are to be considered:

� Materials of construction for the wheel, shaft, and hub
� Wheel to hub attachment
� Materials of construction for the housing including insulation
� Bearings and lubrication
� Shaft seals
� Shaft cooling (air-cooled, water-cooled, etc.)

Limits on the operating temperature for standard fans are defined by the arrangement of the fan. For example, the maximum temperature for a standard fan that does not have a bearing in the airstream can run up to 300F. For standard fans that have a bearing in the airstream, the maximum operating temperature is limited to the maximum temperature that the bearing can handle, which is typically about 130F.

Carbon steel, low alloy high strength steels, and chrome moly steels are satisfactory for a temperature range of 900 to 1000F, depending on stress levels. Heat resistant alloys such as stainless steels (304, 316, 347), Incalloy 800HT, 230, Inconel (600, 625, 617), Multimet, Haynes 25, etc. should be used for higher temperatures up to 1800F. Again, the material chosen also depends on the stress levels and the material properties at elevated temperatures. Temperature derates lower the maximum speed of a wheel to account for the lower material strength at elevated temperatures. The wheel must sustain the highest stress of all the fan components. It is very important that the material used on the wheel is strong enough to handle the stress at high temperatures. At higher temperatures, material eep must be considered.
