Best Value Vacs: The Types
Three different pumping methods — positive displacement, momentum transfer, and entrapment— can be generally characterized.
- Momentum transfer pumps, also known as molecular pumps, force gas molecules out of the chamber using high-speed revolving blades or jets of dense fluid. This type of pump is often used in industrial applications.
- Positive displacement pumps force gas molecules out of the chamber by trapping them in a container and then compressing it, sending the molecules through a discharge valve. These are most often used for consumer goods such as vacuums. Using a mechanism, positive displacement pumps continually inflate a cavity, let gases enter from the chamber, close the cavity off, and exhaust the gases into the atmosphere.
- Entrapment pumps trap gas particles using insulated walls, which prevents them from entering the atmosphere. These pumps are often used in medical applications such as centrifugation, drug delivery systems, and dialysis machines.
Cryopumps, getters, and ion pumps are examples of entrapment pumps, which are used to collect gases that are solidified or adsorbed.
Vacuum Pumps: What To Consider
You must consider a number of aspects while selecting a vacuum pump. Prior to making a decision, consider how it will be used; this will help you decide on the technology, lubrication, chemical resistance, vacuum level, and required flow rate.
- The caliber and required vacuum level should be your deciding factors when selecting a vacuum pump. Vacuums come in several varieties, including rough or low vacuum, high vacuum, and ultrahigh vacuum. The distinction between the three is the rarity of the molecules produced, which is determined by the remaining gas pressure. The number of weak molecules per cm3 increases with decreasing pressure. The vacuum quality is improved as a consequence.
- The technology used is also important when selecting a vacuum pump. Vacuums are generally powered by electricity, gasoline, or oil.
- The lubrication used is another aspect to consider prior to purchasing a vacuum pump. Vacuums that use oil-based lubrication do not require replacement as often as those with water-based lubricants, making them more cost-effective. Additionally, ensure that the pump you select is compatible with any chemicals it may come into contact with in order to prevent damage or malfunction.
- Chemical resistance is especially crucial if the vacuum will be used in medical or industrial applications. Vacuums vary significantly in price depending on their features, but prices can range from a few hundred dollars to several thousand. The cost of the vacuum should reflect its quality; cheaper vacuums may lack reliability
- The vacuum level and flow rate are other aspects to consider when selecting a vacuum pump. Vacuum levels range from 100 bar (rough vacuum) to 0.1 bar (high vacuum). The level of the chamber should accommodate the required flow rate, which is determined by the application.
- The required flow rate is measured in liters per minute (LPM). The amount of air displaced in the chamber should equal the required flow rate.
In conclusion, when selecting a vacuum pump for home use, consider the type, technology, lubrication, chemical resistance, vacuum level, and flow rate requirements. Once you have considered all these variables, you can select the best vacuum pump for your needs.
