Looking At The Design Of Liquid Ring Vacuum Pumps

liquid-ring-vacuum-pumpWhen considering a liquid ring vacuum pump, you want to be sure you are choosing the right pump and the right company to help you supply that pump. There are a few things you need to look at when the time comes for you to purchase one of these pumps which is why it is important for you to do some research on the product.

When Needing This Pump

The first step is to recognize when you need to use this pump. The liquid ring vacuum pump is best used when the gas load is wet. The internal construction makes pumping saturated loads easier without worrying about damaging the pump. This will prove important with heavy loads when you really need to get the job done right. Miniature vacuum pumps might be better suited for smaller jobs.

How It Works

Net pumping can come from the standard pumping curve when you allow the warm process vapors to condense within the cooler liquid ring. This is how the liquid ring guard can help the process unlike oil sealed or dry vacuum pumps that can be used to pump wet gases. Liquid ring vacuums rely on the physical properties in the sealant to help determine the maximum vacuum level. This is how the pump gets the most “bang for its buck” as the saying goes. Liquid vacuum pumps are often used with jobs that require deeper cleaning or an extra pumping stage. The liquid ring vacuum pump can use an extra process that can help enhance the performance. Other types of vacuum pumps do not always have these same options. This is why many people prefer this type of pump to others available today.

What Is Cavitation?

Cavitation is part of the process used with a liquid vacuum pump so it helps to understand this and how it works. Basically, cavitation is the formation of vapor bubbles on a flowing liquid into a specific region where the pressure of the liquid falls below the vapor pressure. Pump cavitation is common most vacuum pumps. Usually this process will be classified as either inertial or non-inertial cavitation. Vacuum pumps typically work with inertial cavitation. This is when the void or bubble in a liquid collapse really quickly making a shock wave. This is important to how the pump works successfully. It’s all part of the scientific process that makes the pump work.

Types Of Pumps

When it comes to choosing a liquid ring vacuum pump, you need to get as informed as possible on the types of pumps out there so you can be sure this is the right one for you. If you’re going with a professional company, you just need to be sure you choose the right one. Thomas and Busch vacuum pumps are renowned for good their good quality, and one should consider these two brand when looking to purchase a vacuum pump.

You want to pick a company with experience in this field so that you can trust the job will be done right each and every day. It’s also helpful to know the type of vacuum pump that you want. There are many great brands on the market today and some brands offer features and benefits that you won’t find in other models. Do some research and you can find the perfect liquid ring vacuum pump for your needs.


A Look at Balance Bike Designs

Industrial design has evolved into a field that has expanded its wings from User Interfaces to product designs. With the help of technology, you can create a wonderful product on your PC and then get it manufactured to get the desired product. Using various design software like Autodesk, it is possible to create absolutely anything. Let us go through such an example with a balance bike as the subject. Here is how to make your own balance bike –

The first step in designing a custom balance bike is the wheels.  As is the case with each step of this project, you’ll want to take into account the size of the child who will be using the balance bike once it’s finished.

Starting with one wheel, sketch circles (Sketch > Circle) to represent the outer boundary of the tire, the hub, and what will likely be a metal frame between the two.

After that, use the extrude tool (Construct > Extrude) to give the wheel the desired thickness, extruding the “hub” and the “metal frame” to slightly shorter levels than the tire itself.  On the other side of the wheel, project the surface, and create the same extrusions on the hub and the frame as the first side.

Using the Modify fillet tool, round off the top surfaces, and then add color to the hub, frame, and tire using Materials.  What started as a few circles should now be looking much more like a wheel.

Once you have finished the first wheel, use the Rectangular Pattern Tool (Pattern > Rectangular Pattern) to create a second wheel, and punch a hole in the center of each wheel.

Use the polyline tool to create the profile of the front fork (really drawing half of the fork), and use the rectangle to create the sketch of the opening for the body. Be sure to use the trim tool (Sketch > Trim) to trim any lines that are not required.

Like you did before with the wheels, extrude the sketch to the desired thickness, and use the mirror tool (Pattern > Mirror) to complete the front fork.

Before you design the handlebars and grips, open the wheels file that you created, group the wheels, and place the model of the fork in the bike assembly (File>Insert>From My Computer).  From there, you can move the fork into place

For the handlebars themselves, first use the project tool (Sketch > Project) to select the top face of the front fork, use a polyline to create a rectangle for the handlebar, and extrude the profile to the desired handlebar thickness. From there, you can apply material and whatever color you’d like to your handlebars.

To put grips on the end of the handlebar, use the project tool (Sketch > Project) to select the end face of the handlebar, sketch a circle on the projected face, and extrude the outside portion of the circle. Repeat the process with a slightly larger circle to place a knob on the end of the handlebars (this is a balance bike for a small child, and we don’t want their hands slipping off the end).

Finally, fillet the sharp edges on the handlebar grip and apply whatever material you like.

Balance Bike Design

For the bike body, start by using the polyline tool to sketch the profile of the body, and extrude the sketch to the desired thickness.  Remember to take into account the height of the rider, and to leave a flat space on the top of the body for a seat.

Once you have finished sketching and extruding the body, move it into position, fillet the sharp edges, and apply whatever material you like.

Last but not least, design the seat.  You’ll want it to line up with that flat space you left on the body.

First, use a polyline to create a sketch of the seat. Tweak the sketch until you’re happy with the shape of the seat, and then extrude the sketch to your desired thickness.

Next, hide the sketch, fillet the sharp edges on the seat, and apply the materials.

Lastly, make sure the seat is in place and aligned, and group all the parts. Once you’ve created your custom balance bike plans, there are a few different choices of assembly.

Depending on your design, you can make a something like a Schwinn balance bike very cheaply using recycled or salvaged building materials.


Okkatots Travel Baby Depot Backpack Bag – Beyond Practical

Product design is a constant exercise and pragmatic trade-offs between, aesthetics, practicality, simplicity, ease of use, functionality, cost and everything else laid out by Dieter Rams. Sometimes however, with some products it’s pretty obvious which of these design considerations need to weigh the most. In the case of the Okkatots backpack diaper bag it had to be practical. If you’ve ever traveled with a baby you will know, that while it’s important that your diaper bag is pretty good looking, nothing trumps practicality in that moment when your baby decides to, well, be a baby. I’ve recently taken a look at this backpack and I have to say, it is a pretty impressive design job.

okkatots-back

The backpack is designed to be a diaper bag as well as an overnight bag. It has been designed to organize everything you may ever need when away from home with your baby into logical en easy to reach compartments. It’s obvious that a lot of thinking had gone into this design with some incredible attention to detail. Take for example the inclusion of a front pouch for a portable DVD player: easy to access, no need to open the bag and an absolute life-saver while you’re sitting on a train, bus or just somewhere in the park with a tired kid that needs a few minutes of distraction.

okkatots-open

The backpack is designed to not only zip open at the top like most backpacks – that would still force you to reach into the bag into a space that you cannot see – the zip goes all around the pack and literally lay it open exposing the multitude of small containers and compartments, all easily accessible. It sports some small mesh holders on the outside for those must reach items like a teether or dummy. Opening up the bag and laying it in front of you is like opening up mission control for the travelling parent! Diapers, hand-wipes, powder, changing mat, spoons, bottles, toys, everything neatly organized and right there at your disposal. Okkatots did a great job at making those important design trade-offs, and while this bag is all about practicality and ease of use it is also comfortable to carry and actually quite beautifully designed. There;s no reason to cringe when you take this into public – in fact, most people will not even know it’s a diaper bag – it simple looks like stylish modern backpack.

From a product design perspective this is in my opinion a great example of how smart design decisions, focused on the user and having one single goal in mind – to make their lives easier – should be done.
