Various Sorts Of Pumps Needed For Liquid Control
Posted by SEO SERVICES in Engineering and Industry on July 9th, 2011
Most people take for granted all of the difficult work that is put into the job of controlling, dispersing or manipulating liquid flow from one area to another. These are the things which generally go unseen by individuals in their everyday lives, meaning that they don’t have to think about how these goals are achieved. However, the talented people who work in the industry of liquid control systems know exactly how difficult it can be to maintain the different pressures and manipulations needed in order to keep these systems running appropriately. Between all of the various complex parts needed, such as air operated diaphragm pumps, positive displacement pumps, diaphragm pumps, drum pumps, high pressure pumps, mag drive pumps, metering pumps, rotary gear pumps and submersible pumps, there are so many different factors at stake that it usually takes an expert in order to figure out any problems.
In addition to repair staff and other liquid control professionals, there are also many engineers who need to work with these air diaphragm pumps or positive displacement pumps on a regular basis. These engineers get to know the ins and outs of the products very well, and they rely on the assistance of liquid control parts suppliers in order to get the task done correctly. When these engineers have located liquid control parts suppliers who not only specialize in this particular industry but also have a huge range of products to offer, they tend to build a lasting relationship with the supplier that leads to years of profits and success. Having every kind of pump, including drum pumps, high pressure pumps, mag drive pumps, metering pumps, diaphragm pumps, rotary gear pumps and submersible pumps, is undeniably important to the engineers as it means that the supplier will be able to help them out with any project that comes up.
In addition to being able to supply these many different types of pumps, particularly positive displacement pumps and air operated diaphragm pumps, it’s important that the liquid control parts supplier also provides repairs on the parts that they offer. This is a huge benefit for the engineers or liquid control professionals who work with these parts on a daily basis because it means that they know they can rely on the supplier to follow up on all of their products. Generally, this leads to items that are of a higher quality than those provided by other suppliers, whether they are a drum pump, a high pressure pump, a mag drive pump, metering pump, diaphragm pump, rotary gear pumps or submersible pumps. Each of these products need sufficient attention and repair at certain times and having a supplier on hand for this work is vital for success.

CNC Lathes - Why They Make Such A Difference
Posted by SEO SERVICES in Engineering and Industry on July 1st, 2011
Introduction
A Computer Numerical Controller refers to a computer that reads machine code instructions in order to control a machine tool. Computer Numerically Controlled, (CNC), Machine tools are generally used for machining raw material stocks into completed designs by carrying out a sequence of these instructions. CNC Lathes are probably the most widely known application of this kind of engineering. They spin a block of material so it can be cut, sanded, drilled or finished, with the end result being a completed three-dimensional item. In reality, CNC lathes are simply the same as a conventional turret lathe, but operating under computer control.
History
The invention and proliferation of electric motors in the early twentieth century inevitably led to traditional types of lathes becoming electric powered. This was the first phase in automating the milling or turning process, It continued rapidly through the 20th century as producers and industrialists increasingly sought to improve efficiency and reduce production costs.
Constituent Parts / Components
Modern CNC lathes are a combination of a computer with a lathe machine and a controller that converts each digital signal into the desired action. Before this the instructions have to be written using specialist software to encode the required actions. The work piece is next fitted on the chuck and rotated at slow or high speeds depending on the material and the type of cut or centering required. The computer then controls the lathe through the cutting action until the finished product is produced. The latest lathes can have up to four spindles to perform multiple jobs simultaneously, which reduces production time and improves productivity accordingly.
CNC lathes are typically equipped with three jaw hydraulic chucks. Work holding is accomplished with hard jaws or bored soft jaws. Lathes may also have a collet chuck. This allows for variable size and precision holding without the need for soft jaw boring. When a lathe is equipped with a collet chuck, it may require a change to the draw bar that connects the actuator to the chuck.
Tool pieces are usually made of hard alloys such as titanium carbide and tungsten carbide, and may vary depending on the material that needs to be processed. They are used until the sharpness reduces below a predefined level. After this level is reached they are either resharpened, or replaced with a new bit.
A skilled operator is still required for a CNC lathe, despite all the advances in computer technology. This is still a much quicker, more productive and more cost effective solution than traditional lathes could achieve. A developer is also required to compile the program commands needed to instruct the equipment in the first place.
Programming a CNC lathe firstly requires a blueprint of the item to be created. The blueprint is then analysed and converted into the programming required to control the lathe. Every move in three dimensions is programmed, in extremely fine detail. A lot of skill and quality review is required at this stage to ensure no problems occur once the program is running in the live environment.
Practical Applications of CNC Lathes
CNC lathes are often used on hard materials such as metal, that require the material to be processed, usually through turning at high speed. They are also frequently used for boring precise holes into such hard materials. The material does not have to be metal, as other materials such as wood and plastics can also be processed quickly and effectively by a CNC lathe. CNC Lathes are widely used for making cylindrical engineering parts such as pistons, gearboxes, etc which require a very high level of precision. Manual lathes are still used by smaller scale craftsmen, where mass production is not an issue, and where the craftsman’s skill is a key part of the production process.
Advantages / Benefits
As a percentage of the market share, CNC lathes have quickly established their dominance. They provide a more rapid turn-round time for complex one-off parts and ensure consistency in quality control and design tolerances. They are designed to use modern carbide tooling and fully utilize modern processes. Three further benefits are reduced production time, reduced inventory and reduced set up times. With the continuing rise in demand for engineered parts, CNC lathes ultimately give higher production volumes, with greater precision and fewer errors.
Summary
CNC lathes are a perfect example of man’s technological achievements bringing real benefits to the general population. Due to their extensive use these days, goods can be produced faster, more accurately and at a cheaper cost than previously.

American Manufacturing Stagnates During The Recovery
Posted by SEO SERVICES in Engineering and Industry on June 17th, 2011
For months the industrial sector has been leading the recovery in the US. Economists pointed to data reflecting growth in manufacturing as a sign that the US economy was on the rebound. However, the recovery in the Manufacturing sector has since stumbled. Growth and job creation, once robust in the sector, dwindled and stagnated in May.
Some areas of manufacturing are still experiencing growth however. For example mining and the manufacturing of tungsten extrusion dies and tungsten carbide tooling remain strong. However, other areas, like the auto industry have experienced setbacks due to the disaster in Japan. Japanese suppliers have been resilient, however power disruptions in the wake of the earthquake and tsunami have impacted their ability to supply needed parts to the Detroit auto makers. Industries related to housing have had little luck as well, in facts housing prices have proven that they have not bottomed out in recent months and have sagged once again. Low prices on existing homes means that construction of new homes will remain anemic in the foreseeable future. Additional factors are worrying manufacturing executives, at the top of their minds is the rising costs of energy, including fuel prices, and soaring costs of raw materials.
The American manufacturing industry is doing better than it has done decades, owners and manufacturing executives remain skeptical, according to a survey released Wednesday by business consultant Grant Thornton LLP. Grant Thornton LLP most recent Business Optimism Index found only 40 percent of respondents surveyed in May saying the U.S. economy will improve in the next six months. The Business Optimism report is generated quarterly and it reflects a 20 percent drop in confidence since February. The survey also found that 16 percent of the owners and manufacturing executives surveyed said they are planning on cutting their work force, up from 6 percent in February.
What this means is that companies will be taking a wait and watch approach over the next 6 months. Executives will be keeping an eye out for any wasteful spending or even any spending that can be put off. Cost cutting initiatives will be launched that can impact the purchasing of new equipment, further weakening the manufacturing sector. As these executives take a hard look at their books anything that can be considered discretionary spending may be cut. Most worrying is that they won’t be hiring new employees and will not be making any large investments, expanding or taking on new large new projects with confidence levels so low.
So what does all of this mean for the US economy? That’s the worse part about it all. The industrial sector has been a bright spot in a generally gloomy economy. There are some up sides though. Despite all of the bad reports, dire projections and the pessimistic views of the manufacturing executives the industrial sector isn’t doing that badly. Companies have more money in the bank and are generally healthier then they have been in the last 20 years.
On top of that some possible relief may be on the way for US manufacturers. President Obama has made plans to find more jobs for Americans. His ideas include training workers for jobs that are tough to fill, such as advanced manufacturing, and streamlining the permit process in hopes of kick-starting infrastructure and construction projects. There is only so much a president can do for an ailing job market though and honestly these programs aren’t likely to excite Manufacturing business owners and management, a group not known for leaning towards the Democratic Party.
The fact is that manufacturing might not be a great thing for Americans to hang their hats on right now, but there aren’t really any great options out there when it comes to finding employment for the 9.7 percent of unemployed workers out there. Hopefully in the end the recent setbacks prove to be nothing more than another bump on the road to a fully recovered US manufacturing industry. One can hope right?

The Resurgence Of American Manufacturing
Posted by SEO SERVICES in Engineering and Industry on May 19th, 2011
Manufacturing in the US has been on the decline for decades. It seemed to everyone that the US would not be able to compete globally in these markets|industries do to the lower wages of foreign works and lack of regulations in third world countries. However, despite this the US manufacturing sector has risen for the previous ten straight months. Once again optimism is beginning to appear in the once great powerhouse of manufacturing; however it is unlikely that we will ever see the levels attained at our height.
Still, US manufacturing is experiencing unexpected growth. Closed down factories are reopening and jobs are being created. The devastated economies of manufacturing dependent states have grown unexpectedly. The State of Michigan for example has the exciting problem of what to do with 500 million dollars in taxes that they never expected to receive. The reason is the current upsurge in manufacturing. In markets where the US has been traditionally strong, such as aviation, we have continued to grow while in other areas like the auto industry there has been a marked resurgence. General Motors has once again become the world?s top automaker and all three of the ?Big Three? are posting profit levels that they couldn?t dream about a year ago.
Still America isn?t producing a lot of the smaller, less technological items that we once did. For example nails and screws haven?t been produced in the US for some time and there is little hope in regaining these markets. However, even in these areas the US has found a niche. Items like carbide dies that are required for making nails and screws take a skilled work to create them and the typical US carbide die maker have been able to rebuff their foreign competition. The reason seems to be that companies using these dies don?t want to risk going with the cheapest suppliers do to the fact that if they have to send an deficient carbide die back to the manufacturer that means production will come to a grinding halt. Apparently managers don?t want to explain why their company is losing millions of dollars a day because they are waiting for a $75 dollar part to the company?s owners.
So why is the US manufacturing sector making a comeback? In short, we are becoming more competitive. US manufacturing has been on a downward slide for forty years, and with it the wages paid to our works has decreased. While the owners of US firms have been doing everything possible to trim wages and cut costs the average wage of Chinese works has gone up at an average of 17% per year. It will be a very long time if ever that Chinese and US workers receive the same wages but it?s a step in the right direction. Coupled with the better education of US workers (yes, we still do have that!) America is finding itself on much more equal footing. The fact of the matter is that if you take an average worker from the Peoples Republic of China and one from the good old US of A, the American worker is more skilled on Average. Another advantage is fuel costs. US industries tend to be closer to the major consumer markets and have more reliable access to power.
The disaster in Japan has been a mixed blessing. While US auto production has surged pass Japanese we are finding ourselves hampered by lack of Japanese parts we use in our own cars. It still remains to be seen if the disaster will be a net gain or loss for domestic auto makers. Similar stories are playing out in the electronics, chip manufacturing and other industries. In fact, this month has been the first month without growth in the US manufacturing sector and the reason cited is supply chain problems stemming from the disaster in Japan.
So, US manufacturing is rebounding, but the fact of the matter is that it has a very long way to go if we ever want to reach our former heights of productivity. The fact of the matter is that growth is slow and it will be about ten years before we even hit the levels attained before the economic crash. Of course, the good news is that we are finally on that path and experiencing widespread, if slow paced, growth.

Tips About Industrial Cooling Solutions
Posted by SEO SERVICES in Engineering and Industry on April 2nd, 2011
The immense heat of summer is at its height in the southern hemisphere of our planet, and up here on the north side it is also not many months away. One matter that unites all of us living in hot areas is the problem of how to handle the agonizing heat during the hot seasons, whenever it may be. Now days most people have air conditioners installed in their homes, as well as in their offices, public transportation or official buildings, making it possible to create a comfortable environment, safely sheltered from the heat. Nevertheless, for many people working in factories, in warehouses or outside, there is in many cases no protection against the heat during the work day. Many factory owners deem it too high cost to install a central air conditioning system, and indeed, the electrical charge for cooling down a whole factory or warehouse facility would quite high. Nevertheless one cannot but help to think that there must be something that can ease the workers hardship in such locations.
Fortunately, lately there have appeared some pretty incredible options for these kinds of situations. The most interesting of which is the so called spot cooler, which basically is a powerful portable air conditioner, designed for industrial use. Unlike the central or split system air conditioners, the purpose of the spot cooler is not to cool down the whole facility where people are working, but rather just the specific work stations themselves. Imagine a large factory with a largely automated assembly line and just a few work stations where people actually do work. During the hot seasons the midday temperature often reaches 45? (113
