DKF electric air vent

First, use WFB series of electric air control valve is used to block a special exhaust system WFB series self-priming pump siphon phenomenon. Second, the principle Kai pump: motor power operation, the control module is energized, the magnetic pull promote stem the sealed chamber closed, the pump inlet tube to form a vacuum pump suction. Stop the pump: The motor stops running, the control module is energized, magnets and push the stem by the spring reaction airtight chamber is opened, air enters the pipette from the hermetically sealed chamber of the pump chamber and the inlet pipe siphon liquid separation block, ensure that the pump chamber has Water suck liquid enough to prepare once again self-absorption. Third, the model and equipped with electric air control valve model DKF- DN15-A DN20-A DN25-A DN30-A DN32-A DN40-A DN48-A DN50-A DN60-A DN15-B DN20-B DN25-B DN30 -B DN32-B DN40-B DN48-B DN50-B DN60-B DN15-C DN20-C DN25-C DN30-C DN32-C DN40-C DN48-C DN50-C DN60-C equipped with pumps 16WFB-65WFB 80WFB-125WFB 150WFB-800WFB electric automatic air valve function: electric control valve is one important part of self-priming pump, start the pump when the pump suction solenoid valve closed air inlet tube on that Self priming chamber forming a vacuum inside, complete self-absorption process. When the pump stops solenoid valve is open, air from entering the pump suction mouth sealed within the lumen of the rapid isolation dielectric liquid inside the pipette with a total flow of the pump chamber, to ensure that the media does not pump cavity with aspiration lumen of the media down to wash pool in order to eliminate the siphon purpose, ensure that the secondary priming pump self-absorption and self-absorption to normal operation. Electric air control valve is a self-priming pump WFB Series sealed an important part. It has designed, compact, sensitive, safe and reliable, high degree of automation. Solenoid valve advantages: 1, the electronically controlled valves sealed package using polypropylene, rubber piston, has a good dust, corrosion resistance. 2, the electromagnetic coil using high-voltage startup, low retention work. Avoid long-term electromagnetic coil easy to heat damage due to high pressure instability. 3, solenoid AC input, low voltage DC power supply coil, thus greatly reducing the power consumption of the solenoid valve.
