Application of constant current pump in ink-jet printing machine

Constant flow pump can transport all kinds of inks with high viscosity, and its suction distance and Yang distance can be more than 5 meters Moreover, constant flow pump can change the conveying direction at will and also has the function of stop valve It can cancel the configuration of one-way valve in the pipeline The conveying accuracy can reach 1%, and the speed regulation is not always convenient Therefore, as an ink pump, constant flow pump is a very ideal choice In the process of high-speed ink-jet printing, ink needs to be continuously delivered to the nozzle, and the ink in the ink cartridge will be continuously reduced In order to ensure the continuous supply of ink, the ink tube is usually inserted into the external ink barrel to pump the ink to the secondary ink cartridge for transfer Ink jet printer usually uses diaphragm pump as ink delivery pump, or uses diaphragm pump to collect and discharge waste ink Although this kind of pump is cheap, but for some solvent based inks or inks with high viscosity, the pump will be damaged or the flow rate will be unstable in the process of transportation, at the same time, it will also bring problems such as ink dead angle residue in the pump 104k / ZL is a constant speed micro constant current pump, which is driven by 12V or 24V DC power supply, and the flow size can be selected (select motors with different speeds) The 104k / ZL constant current pump is equipped with a DC decelerating gear motor, which ensures that the 104k / ZL constant current pump always maintains super high reliability and stability in the process of delivering ink, and will not cause the phenomenon of no liquid or no ink pumping due to the abrasion of the pump pipe There are some constant current pumps without reducer, which surround three wheels outside the motor shaft The shaft is very small, the wheel is large, and the shaft rotates at high speed, driving three wheels to do planetary operation All of them are driven by the friction between the shaft and the wheel If the pump pipe is worn and the wheel is worn, the pump will stop discharging liquid, even when the outlet resistance increases.
