Follower Plate Pump
{{Unreferenced, date=June 2019, bot=noref (GreenC bot) image:Schoepfkolbenpumpe mit Vakuumplatte.png, 250px, A scooping piston pump used with follower plate. The red arrows show the flow of the material, the blue ones the movement of the piston and the white arrows show, how the air is sucked out underneath the disposable follower plate A follower plate pump is a device to pump highly viscosity, viscous material directly from barrels. So it sometimes is called a barrel follower plate pump. It is applied in food manufacturing, resin dispensing {{Unreferenced, date=May 2009 A resin dispensing system is a technical installation to process casting resin for the purpose of filling, sealing, covering or soaking technical parts, especially in the field of electricity and electronics like tran ..., gluing and so on. The principle If an ordinary intake socket is lowered into highly viscous material, the material will flow so slowly, that after short time, the pump will soak up air, becau ...

Viscosity
The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness": for example, syrup has a higher viscosity than water. Viscosity quantifies the internal frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's axis than near its walls. Experiments show that some stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube with a constant rate of flow, the strength of the compensating force is proportional to the fluid's viscosity. In general, viscosity depends on a fluid's state, such as its temperature, pressure, and rate of deformation. However, the dependence on some of these properties ...

Resin Dispensing
{{Unreferenced, date=May 2009 A resin dispensing system is a technical installation to process casting resin for the purpose of filling, sealing, covering or soaking technical parts, especially in the field of electricity and electronics like transformers, LCDs and other devices of various size. Due to progressing miniaturization and introduction of electronics into new areas, quality requirements for the parts are rising, and thus the quality of dispensing must be increased as well. To obtain the required quality, on one hand, the resin system has to be developed and optimized accordingly. On the other hand, the resin dispensing system has to work more and more precisely to obtain best dispensing. Because of continuously increasing cost pressure, casting devices must be capable of increased quality, while also becoming faster and more reliable. Requirements for good dispensing First of all, by dispensing, electrical and electronic parts have to be insulated reliably and penet ...
