A Brief Overview about Turbomolecular Pumps

There are various kinds of vacuum pumps available and used throughout the market. One that has gained notoriety in the last few years is known as a turbomolecular pump These pumps consist of a stator with turbine-shaped blades as static  blades and a rotor with rotating  blades. 

Workings of TMPs

The rotor blades rotate thousands of times, usually between 24,000 to 80,000 rotations per minute. This process creates and maintains vacuum. The principle that is followed by TMPs is that gas molecules will move in a specific and predicted direction when they come in forceful contact with  the solid surface of rotating blades. The blade collides with the gas molecules transferring to them the kinetic energy necessary to push them into the static part and then to the second rotating stage The gas moves through multiple compression stages, finally flowing through the exhaust port.. These pumps need a backing pump to work properly.. The performance of the pump depends on the rotational speed of the rotor.

Types of TMPs

Turbomolecular stages are particularly useful in  harsh processes where  dust or particles are present and can be coupled to drag stages to increase the pump compression capacity and get higher exhaust pressure (and as a consequence smaller and cheaper backing pumps) See Aglient turbomolecular pumps web site for more info. 

Advantages of TMPs

There are several reasons behind the popularity of TMPs

  • They are very easy to operate
  • Turbomolecular pumps require lower maintenance when compared with other kinds of vacuum pumps
  • Low vibrations are generated by TMPs (A benefit in many applications)
  • The operation is free of hydrocarbons 
  • No regeneration is required by these pumps
  • Constant pumping speeds is provided by turbomolecular pumps
  • These pumps are also quite reliable since they can be used constantly, even 24/7
  • They have a high tolerance to moisture
  • They can be very compact and can be combined with a dry primary pump very easily
  • They provide the cleanest conditions since they do not backstream oil into the vacuum system

Applications of  TMPs

Turbomolecular pumps are widely used in various environments.

  • Analytical instruments or R&D are some of the cleaner uses of TMPs
  • They are also sometimes used in the semiconductor industry for manufacturing in quite harsh conditions
  • These pumps are also used in deposition equipment
  • Sputtering equipment  vacuum coating plants often uses turbomolecular pumps 
  • They are used in particle accelerators
  • Manufacturing equipment for flat panel displays also makes use of TMPs

Numerous types of turbomolecular pumps are readily available in various sizes.

8 Ways To Help Combat Climate Change

Published

on

You’re just one person in a world full of billions of people. It may seem like your actions won’t affect the planet that much so it doesn’t matter what you do, but that just isn’t true. If you are passionate about tackling climate change, and you really want to make a difference, here are eight steps you can take:

Reduce energy consumption in your home

If you are in the United States, your average annual carbon footprint is about 16 tons, which is about 4 times the global average. Roughly one third of that is home energy consumption, so this is a great place to start reducing. Even small things like switching your bulbs to LEDs can make an impact, but big things like weatherizing and insulating your home can make a huge difference.

Take some time to analyze your home energy consumption by getting a professional home energy audit. At the very least, conducting an online energy assessment can give you some helpful insights of where to start making changes.

Adjust your transportation habits

The next biggest category for Americans when it comes to energy consumption is transportation. Easy ways to make a difference here will depend on your location and lifestyle, but here are some ideas: get an electric vehicle, fly less, walk or bike to work, use public transportation and carpool. No matter what your lifestyle, there are changes you can make to reduce your impact in this area.

Change the way you eat

Most people know that eating less meat is the number one way to reduce your carbon footprint when it comes to food. But few recognize how important it is to simply waste less food. Americans waste about 40% of the food they buy, according to the National Resources Defense Council.

By planning meals, using better food storage containers and buying only what you need, you can reduce food waste drastically. The good news is that this will reduce your food budget along with reducing your carbon footprint. It’s estimated that wasted food accounts for about $1,800 per year.

Support clean energy

If you can use solar power or wind power and other renewable energies, you can make a huge impact on climate change. Some people are even able to choose which energy cooperative they purchase from. Support clean energy in any way you can.

If you are a homeowner, investing in solar power is an investment that will continue to pay dividends, especially when you factor in net metering. Net metering allows solar customers to create energy during the day when energy use is low, export that power to the grid and reduce their future electric bills. There are also ETFs and solar company stocks that you can invest in to support the industry.

Vote for a climate activist

It might not seem like much, but supporting climate activists can be extremely productive in the fight against climate change. These people are leading the charge in a politically heated arena, and it can get lonely when you are championing controversial ideas. Reach out to climate activists and let them know they have your support. If you can, offer to become a part of their projects or donate to their cause.

Work from Home

While this option isn’t available to everyone, WFH can have a huge impact for those who can reduce their commutes by even one day per week.  There are many benefits to WFH, but your employer might not realize how important this one is to you if you don’t say anything.

Even if you aren’t in a position to WFH, speaking up about the beneficial impacts that working from home can have on combating climate change is a great way to impact climate change issues. Creating awareness is a step in the right direction.

Recycle

In America, there are many communities that are recycling. If your community isn’t one of them, this could be the biggest way for you to make an impact. Don’t try to do this alone, though. Find a group of like-minded people and get them involved. 

Recycling is supported by most people, and it is considered by many to be a priority. But the rate that we recycle in the United States is only 32%, according to a U.S. Census report, so there is a lot of room for growth here.

Buy less

Manufactured goods like household items and clothes end up in our landfills. If you want to make a big change, stop buying items you don’t actually need. Spending accounts for about one quarter of most American’s carbon footprint. In fact, your carbon footprint rises with your income level, so it is those with the highest incomes that can make the biggest difference. Try taking the money you would spend on shopping sprees and use it to support an organization that is fighting climate change.

Do at least one thing to tackle climate change issues

Even if you only take one of these eight steps to combat climate change, it is better than doing nothing. And who knows? You might feel so good about taking that first step that you will want to continue on this path.
