There are a number of vacuum pumps on the market that make it possible to perform a wide variety of different jobs. But if you're not familiar with how they work or what they do exactly, you might be wondering where to begin. Don't worry - we've got your covered! Check out our ultimate guide to vacuum pumps and get started on your path today.
1. What is a vacuum pump and what can it do?These devices are designed to suck in something, such as a vacuum cleaner, and then expel the rest. Since the device uses a vacuum, it needs to be able to function correctly no matter what it's sucking up or spitting out. That means this pump functions by transmitting vibrations to some sort of receiver, similar to how a remote controls your vacuum. These vibrations travel in both directions, and depending on what you're throwing into the machine, can move and rotate it in all sorts of different directions. This enables the vibrations to do a number of jobs, from picking up and holding onto small, loose particles, like crumbs and small mounds of sand, to getting those stuck-in-your-jarbraker proteins out of the way. Once the protein mess is out of the way, the pump can then move on to another small item as if nothing had happened (since it wasn't blocked from moving in any way). Of course, if a big particle ends up stuck in there, that may mean that there's no vacuuming to be done today, even if the pump is on.
When the user places an item into the vacuum, these vibration jets will also propel it forward in a predefined path, e.g. in a vertical or horizontal line. Apart from carrying items from A to B, you could also use one to move items in a specific direction in the opposite direction, e.g. in the opposite direction of where you want to go. In order to do this effectively, there are two things that a vacuum pump needs to do. First, it needs to be able to distinguish between what it is it is sucking up and what it is sending up to the receiver.
2. How does a vacuum pump work?A vacuum pump is a mechanical device that removes air from a sealed space. The vacuum that results is called a partial vacuum. A vacuum pump is often used to create a partial vacuum in a laboratory. A partial vacuum is one in which the pressure is lower than atmospheric pressure but higher than it would be if the space were empty.Different types of vacuum pumps have specific applications, and not all vacuum pumps work the same! Making this confusion worse, most vacuum pumps on the market both operate with dry discs and wet discs, which may confuse you further.
So which type should you buy? Well, the most significant difference is the type of hose that vacuum pumps use. Dry-pump hoses can be either flexible or non-flexible. Some vacuum pumps rely on a flexible hose to remove air from the interior of the chamber. These hoses can be stretched quite thin, usually around 25 to 30 mils (0.125 to 0.36 inches). On the other hand, wet-pump hoses are usually flexible and can be larger in diameter than 25 mils.Some types of vacuum pumps also include a micrometallurgical cleaner. This type of cleaner is designed to remove particle invaders and other small debris from small openings. These types of vacuum pumps are usually fairly inexpensive and can easily be located by Googling "vacuum pump".
Below we've summarized the main differences between the most common types of vacuum pumps, as well as additional features and specifications you should take a look at when picking one up.
When purchasing a vacuum pump, it's important to get one that matches the specifications of the task that you're going to perform. In general, the larger the diameter of the hose, the higher the vacuum range. The larger the reservoir, the longer the pump should be capable of pumping, and the more powerful the motor should be.
The type of hose will also determine how often the pump will need to be cleaned, as well as how often the vacuum needs to be replenished.
3. Are there different kinds of vacuum pumps, and what are they used for?Vacuum pumps are connected to a power source, usually an inverter, through a small DC power cable. The power cable connects to a VAC (voltaic alternating current) circuit that runs through the vacuum enclosure and into an external power source, usually a motor. All modern vacuums have multiple output modes, including a Reverse Output Mode (ROM) that turns off the motor entirely when the pump is turned off. When a vacuum is sucking up household dust, it's only a matter of time before you need a vacuum pump for your home or office.
For obvious reasons you don't want to run a vacuum with just any old power cable. We suggest you get a power supply rated for 10 Amps to 20 Amps (A) and a plug rated between 18 to 29 AWG. If the power cable only allows for 5 A or less, you'll have to find a step-up converter (SPAC) to make up for the difference with a higher capacity power cable. With a known voltage power supply, a 15-A SPAC usually costs about $14, while a 20-A SPAC will cost about $36. Keep in mind that you'll need a power supply to connect to the inverter as well. The following table shows the basic inputs/outputs that a vacuum pump has:You'll probably want a power supply to run your vacuum as well. Luckily and unfortunately there is no hard online answer when it comes to this. For about $50 to $100 you can find table-top power supplies, from reputable companies like Eheim and Hayes. Make sure the AC input voltage is at least 12 Volts. Make sure both input and output voltage levels are at least 47 Volts.
4. Where can I buy a vacuum pump, and how much will it cost?First things first, a little bit about vacuum pumps. These devices suck airborne dirt, items, and even hair and other organic matter into a chamber below the vacuum itself. The chamber is lined with a dense mesh that traps and absorbs any under-sized items that run into it while being sucked up into the chamber. The actual vacuum is generated by directing air through a special transducer as the vacuums brushes across the mesh. This process sucks up the small debris and occasional value items that find themselves in the path of a vacuuming vacuum.
There are two main categories of vintage vacuum pumps:
The first type is built to resemble either a gas or electric coffee press. It works by sucking air into the chamber using a diaphragm. This forces air through a series of circles. The longer the air movement, the more air is sucked into the chamber. The larger the diaphragm, the stronger the sucking force and the greater vacuum generated. As we've conveniently already determined above, the stronger the sucking force, the greater the vacuum and the cleaner the area that's being cleaned. This is a common design for the earlier vacuum pumps, whereas the later models tend to be more modular in design, letting you control exactly how much vacuum you're generating. Vacuuming devices typically come in a number of different configurations, from those that look like modern household appliances to ones that resemble cornucopias and vending machines.
The second type of vacuum pump looks very much like our parents' old VCRs. This vacuum pump has ridges and indentations that mimic the ridges and indentations when pressing an old VCR to record a new episode of You Can't Do That on Television.
