Rubber Rubber Processing: Rubber processing consists of four basic steps: (1) mastication, when the elastomer is sheared and the molecules are broken down to give easier flow, (2) mixing, usually carried out immediately after mastication, when additives are incorporated, (3) shaping of the viscous mass, for example, by extrusion or molding, and (4) curing, when the polymer molecules become
Elastomeric pump couplings consist two metal hubs that attach to both the motor and pump shaft. Between them is a hard rubber, EDPM Neoprene or urethane insert. Spacer designs are sometimes needed if a large distance between shaft ends exists. There's no maintenance necessary with this coupling, as it does not need lubrication.
Some advantages of this method include being suitable for rubber compounds with large surface areas, and the ability to be used for rubber compounds with high viscosity and poor flow properties. On the down side, the process is time consuming with a low production rate. Some of the common products made with the compression molding process
Pumps, Traditional Water devs, including pumps, are used for moving or lifting water from one location to another. Simple water devs have been in existence for thousands of years and were used for irrigation,domestic water needs, and livestock production.
Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another.They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities. There are many different types of hand pump availe, mainly operating on a piston, diaphragm or rotary vane principle with a check valve
Apr 30, 2020· A Squeeze Pump. You can buy one of these online or you can make your own. If you want to make your own, you need to find a rubber ball and a plastic tube. Then follow these steps: Cut a circular hole in the rubber ball with the same outer diameter as the plastic tube that you're using. Stick the tube into the rubber ball, but not all the way.
Dec 17, 2011· The basic construction of the most flexible couplings consists of two flanges or hubs, which attach to the shafts being coupled, and a connecting element that may be metallic (such as in disc couplings), or a sleeve made from elastomeric material such as EPDM rubber, neoprene, Hytrel or urethane, or a mechanical connection (as in a u-joint or gear coupling).
Chain pumps were also used in ancient China by at least the 1st century A.D. In China, they were also called dragon backbones. One of the earliest accounts was a description by the Han Dynasty philosopher Wang Chong (A.D. 27–97) around A.D. 80. Unlike those found in the West, chain pumps in China resembled the square-pallet type instead of the pear-shaped bucket [dubious discuss].
