subject: Different Types Of Marine Pump Animations [print this page] You can learn quite a bit from looking at pump animations for marine pumps online. If you are confused about the way that pumps work, even after reading description after description, remember that a picture is worth a thousand words, and you will probably be able to sort everything out with a quick glance of a picture.
Take the diaphragm pump animation, for example. Trying to describe the way that these work with words can get confusing pretty quickly. A picture, and a moving picture at that, is an excellent way to get an accurate idea of how the different mechanisms work. Even though there are many different variations of this type of pump, it is a positive displacement mechanism that uses the reciprocating properties of rubber, thermoplastic or Teflon diaphragms and check valves to pump fluids of different kinds for different applications. Confused yet? Now get on the Internet and do an image search for diaphragm pump animation and take a look at it. Simple, isnt it?
Even though reading a description of how these systems work can seem confusing, taking a look at a good pump animation can sum everything up and answer a lot of your questions in just a matter of minutes. Something else that can be confusing is the fact that different mechanisms can be addressed by different identifying names. For example, the previously mentioned diaphragm pump is also known as a membrane pump. In addition to that, there are three main types of these! The first type is one that uses volumetric positive displacement, where the main mover of the diaphragm works through a geared motor drive or a crank and is electro mechanical. Many people like this method because it flexes the membrane through simple, easy to maintain actions. Also, one side of the membrane is open to air. Which type of device are you looking at a diagram of? Make sure that any diagrams that you look at are labeled so that you know exactly what you are looking at!
Another type of system is one where the membrane is sealed with one side in air or hydraulic fluid and the other is in the fluid that is to be pumped. The membrane flexes, causing the volume of the inner chamber to increase and decrease. These models should always have a system pair of non return check valves so that the reverse flow of fluids is prevented. If you think all of this sounds confusing and you are all but lost, be sure that you look at pump animations to achieve a crystal clear idea of what you need to know.
