A peristaltic pump is a type of positive displacement pump used for pumping a variety of fluids, they are also commonly known as roller pumps. The fluid is contained within a flexible tube fitted inside a circular pump casing (though linear peristaltic pumps have been made). A rotor with a number of "rollers", "shoes", "wipers", or "lobes" attached to the external circumference of the rotor compresses the flexible tube. As the rotor turns, the part of the tube under compression is pinched closed (or "occludes") thus forcing the fluid to be pumped to move through the tube. Additionally, as the tube opens to its natural state after the passing of the cam ("restitution" or "resilience") fluid flow is induced to the pump. This process is called peristalsis and is used in many biological systems such as the gastrointestinal tract. Typically, there will be two or more rollers, or wipers, occluding the tube, trapping between them a body of fluid. The body of fluid is then transported, at ambient pressure, toward the pump outlet. Peristaltic pumps may run continuously, or they may be indexed through partial revolutions to deliver smaller amounts of fluid.[Wikistä]
Peristaltic pumps are a type of positive displacement pump used for pumping a variety of fluids. The fluid is contained within a flexible hose or tube fitted inside the pump casing. The actual pumping principle, called peristalsis, is based on alternating compression and relaxation of the hose or tube, drawing content in and propelling product away from the pump.
A rotating shoe or roller passes along the length of the hose or tube creating a temporary seal between the suction and discharge sides of the pump. As the pump’s rotor turns this sealing pressure moves along the tube or hose forcing product to move away from the pump and into the discharge line. Where the pressure has been released the hose or tube recovers creating a vacuum, which draws the product into the suction side of the pump, the priming mechanism.
Combining these suction and discharge principles results in a powerful self-priming positive displacement action.
Peristaltic Pump Filling Machine Principle
Peristalttinen pumppu koskettaa ajoittain vain kirurgisen (tuote)letkun ulkopintaa, joten tuote koskettaa vain letkun sisäpintaa. Täytön päätietokone seuraa itsenäisesti peristalttisen pumpun pään #-kierrosta, jotta se tietää tarkalleen, kuinka paljon tuotetta on syötetty. Kun tavoiteltu täyttömäärä saavutetaan, pumppu pysähtyy eikä jäljellä oleva tuoteneste tipu ulos pipetin toiminnan vuoksi. Tietokone tallentaa kaikki täyttöparametrit muistiin nopeita vaihtoja varten.
Sovellus:
Suunniteltu erityisesti suurten arvojen ja pienten tilavuuksien täyttöihin erittäin suurella tarkkuudella. Sopii vesipitoisille ja muille kevyen viskositeetin omaaville tuotteille.
Esimerkkejä:
Lääkevalmisteet, hajusteet, eteeriset öljyt, reagenssit, musteet, väriaineet ja erikoiskemikaalit.
Edut:
Nestekanava on kertakäyttöinen; helppo puhdistaa ja ristikontaminaatio-ongelmien välttäminen. 0,5%:n tarkkuus on saavutettavissa alle 1 ml:n täyttötilavuuksilla.
VKPAK automatic peristaltic pump filling system is an easy to use table-top filling system. It’s suited for small volume fills involving light viscosity products. Its ease of use, quick change over, and no risk for cross contamination make it an ideal filling option for pharmaceutical preparations, perfumes, fragrances, reagents, essential oils, inks, dyes, thin paint, and various other specialty chemicals. This automatic peristaltic pump filling system can be easily be upgraded to as many as 24 channels to meet larger filling needs should they arise. A variety of tubing materials and sizes are available to match your specific product and budgets. Very inexpensive tubing can be used and then discarded, saving costly clean-up time, also, the system pumps most products directly from your bulk tank which eliminates transfer of product from one tank to another.
Täyte: Bottle by oscillation tidy up the bottle opener for positioning disk thick, by positioning disk again intermittent drive to filling, stoppering, cover, screw cap. Solution by peristaltic pump suction by silicone pipe, at the filling station again by the needle can be moved up and down automatically filling liquid in the bottle.The needle every move up and down, to complete a filling.
Rajoitus: Kiinnitä pullo uudelleen asettamalla pulloon kiinnitettävä levy, kierrekorkki ja kiinnitä samalla periaatteella. Puristaminen tapahtuu sylinterin avulla. Se peittää eri kokoisia pulloja jatkuvasti pyörivillä ruuvikansilla alla ja tekee kaiken ylös ja alas. Kun pullo pysähtyy oikein, kierrekorkin viimeistely estää pyörimisen. Kierrekorkin runko on suunniteltu jatkuvalla vääntömomentilla pullonkorkin ja pullon kierteiden mukaan. Näin ruuvikorkin kierre kiinteys voidaan säätää automaattisesti paikalleen asettamisen jälkeen. Tämä mahdollistaa pullon sulkeutumisen.
