MICROPOMPA SI PROCEDEU DE REALIZARE A ACESTEIAMICROPUMP AND PROCEDURE FOR MAKING IT
Rezumat: Invenția se refera la o micropompa si la un prpocedeu de realizare a acesteia. Micropompa, conform invenției este constituita din următoarele parti componente: doua valve electromagnetice identice (1), fixate intr-un circuit imprimat (2), dintr-un actionator termopneumatic format dintr-un tub închis la un capat (3) care prezintă un strat de metal depus pe suprafața exterioara a acestuia (4), dintr-o folie de polidimetilsiloxan (5) in care sunt practicate doua canale perpendiculare unul pe celalalt (6). La unul din canale se conectează actionatorul termopneumatic. Păduri feromagnetice (7) sunt atașate perpendicular pe unul din canalele (cel poziționat deaupra electromagnetilor) practicate in folia de PDMS.Abstract: The invention relates to a micropump and to a process for its realization. The micropump according to the invention consists of the following components: two identical solenoid valves (1), fixed in a printed circuit (2), of a thermopneumatic actuator formed by a closed tube at one end (3) having a layer of metal deposited on its outer surface (4), of a polydimethylsiloxane foil (5) in which two channels perpendicular to each other are applied (6). The thermopneumatic actuator is connected to one of the channels. Ferromagnetic forests (7) are attached perpendicular to one of the channels (the one positioned above the electromagnets) practiced in the PDMS foil.
Descrierea invențieiDescription of the invention
Invenția se refera la o micropompa constituita din doua valve electromagnetice care ationeaza in tandem cu un actionator termopneumatic si la un procedeu de realizarea a acesteia.The invention relates to a micropump consisting of two solenoid valves that operate in tandem with a thermopneumatic actuator and a method of making it.
Transportul fluidelor in format microfluidic are o arie imensa de aplicatii, cum ar fi sinteza chimica pentru mici cantitati de substanțe, procese biotehnologice, analize de laborator, imprimerie tipografica etc. Pentru a se realiza acest transport de lichide se utilizează pompe miniaturale sau micropompe care, in majoritatea cazurilor conțin piese (cum ar fi pistoane, roti dintate etc.) prin mișcarea carora se realizează pomparea lichidului. Aceste tipuri de pompe avand piese in mișcare sunt predispuse la uzura de frecare, cu consecința scăderii fiabilității echipamentului care conține o astfel de micropompa. Ele au deasemenea o construcție complicata.The transport of fluids in microfluidic format has a huge range of applications, such as chemical synthesis for small quantities of substances, biotechnological processes, laboratory analysis, printing, etc. Miniature pumps or micropumps are used to carry out this transport of liquids, which in most cases contain parts (such as pistons, gears, etc.) by the movement of which the liquid is pumped. These types of pumps with moving parts are prone to frictional wear, with the consequence of decreasing the reliability of the equipment containing such a micropump. They also have a complicated construction.
In patentul SUA nr. 7 299 815/2007 este descrisa o micropompa care utilizează fenomenul piezoelectric pentru transportul lichidelor. Pompele piezoelectrice prezintă dezavantajul ca necesita tensini de lucru de ordinul zecilor sau sutelor de volti.In the US patent no. 7 299 815/2007 describes a micropump that uses the piezoelectric phenomenon to transport liquids. Piezoelectric pumps have the disadvantage that they require operating voltages of tens or hundreds of volts.

Micropompa, conform invenției, înlătură dezavantajele pe care alte tipuri de micropompe le au, prin aceea ca utilizează un actionator termopneumatic in tandem cu doua valve elecromagnetice miniaturale.The micropump, according to the invention, removes the disadvantages that other types of micropumps have, in that it uses a thermopneumatic actuator in tandem with two miniature solenoid valves.
Micropompa, conform invenției, prezintă următoarele avantaje:The micropump, according to the invention, has the following advantages:
- necesita o tensiune mica de lucru (mai mica de 10 V);- requires a low working voltage (less than 10 V);
- are un consum energetic redus;- has a low energy consumption;
- are o construcție simpla; .- has a simple construction; .
- elementul actuator termopneumatic nu are elemente in mișcare, ceea ce permite efectuarea unui număr mare de acționari fara uzura.- the thermopneumatic actuator element has no moving elements, which allows a large number of actuators to be carried out without wear.
Se da in continuare un exemplu de realizare a invenției, conform Figurii 1.An embodiment of the invention is given below, according to Figure 1.
