What are Vacuum Pumps? Vacuum pumps can be described as mechanical devices that remove air and gas molecules from sealed areas to make it gas-free. Their purpose is generally to seal and clean. It can be either Dry Vacuum Pump or Wet Vacuum Pump, depending on what media is being pumped through them and what the application is? Where can Vacuum Pumps be Used? Vacuum pumps can be used in many industries and applications to remove gas molecules and air from processes (Non Condensable Gasses), including the food and beverages industry, semiconductor and electronic industry, pulp and papers, medical, plastics, and woodworking, to name a few. Vacuum packaging machines, Vacuum picking machines, Vacuum lifting, Filling, holding, and drying components are all common applications of vacuum pumps. A). Vacuum pumps Performance Pumping Speed/Rate: The main factor that determines a vacuum pump’s performance is its pumping speed. This is the rate at which air and gas can be removed from a volume. Pumping speed, also known as volume flow rate, is often expressed in units of volume at the inlet of a vacuum pump. It is important that you note that pumping rates depend on the chemical composition and type of pump being used. Some gasses are more efficient than others, for example, entrapment and momentum pumps. B). Throughput Throughput is another indicator of the performance of a vacuum pump. Throughput is the ratio of pumping speed to the inlet gas pressure. It calculates the number of molecules that are pumped per unit time at a constant temperature. When assessing a system leak, throughput can also be useful. This allows you to calculate the volume leak rate multiplied with the pressure at the leak's vacuum side. The leak throughput can then be compared with the pump throughput. Positive displacement and momentum transfer pumps also maintain constant pumping speeds. However, the chamber's pressure decreases and the volume has less mass. The throughput and mass flow rate fall exponentially, but the pumping speed stays constant. The system's throughput remains constant due to the constant leakage, evaporation and sublimation rates. C). What is the life expectancy of a vacuum pump? Its energy consumption is the most costly component of a vacuum pump's lifespan cost. The average vacuum pump's energy cost is five times higher than the purchase price, while its maintenance costs are around 30%.
D). What is the Vacuum Level for Industrial Vacuum Pumps The quality and desired vacuum level are the most important factors in choosing a vacuum pump. There are three types:
E). What is a Two-stage Vacuum Pump? When producing UHV vacuum levels within an industrial pump capacity, a two-stage vacuum pump design is preferred. Two-stage designs have two sets of rotors or vanes. They can use a low vacuum stage or a high vacuum stage. The high vacuum stage absorbs processed gas and then transfers it to a second low vacuum stage. This lowers the gas to atmospheric pressure, increasing the pump's vacuum performance. A two-stage vacuum pump is the best choice if you require higher pressure and better vacuum performance. F). What Technology is Used in Vacuum Pumps Vacuum pumps can be used in many different environments, some most common industrial vacuum pumps are as follows:
Choosing the wrong selection of your vacuum pump can be a costly mistake and potentially damaging to your operation. Before buying a vacuum pump check out the above points. To find out more about choosing the right vacuum pump for your operation, visit our website.
