Application of micro diaphragm pump in inkjet printing industry

Background Introduction
Inkjet printers, which are used to spray ink droplets onto a printing medium to form words or images.
There are two main types of inkjet printing technology: continuous inkjet (CIJ) and on-demand inkjet. Continuous inkjet technology is mainly used in industrial and professional printing systems. On-demand inkjet is a random inkjet system in which ink is sprayed only when printing is needed, which has a relatively wider application range.
Regardless of the type of inkjet printer, professional inkjet technology requires the perfect combination of all technical components to achieve the perfect printing effect.In order to achieve this goal, the micro diaphragm pums plays a vital role.

The roles of diaphragm pumps in inkjet printing equipment
- To vacuum and pressurize the feeding system;
- Conveying water and solvent-based inks;
- Refill ink container;
- Remove excess ink from the print head and remove ink-breaking material for the storage tank;
- Clean the print head and ink drain system.

The application difficulty of diaphragm pump in inkjet printer
1. Continuous inkjet (CIJ) process uses a pressure pump to pump the ink jet into the nozzle. If it is continuous inkjet printing, the operation time is longer, the air pump needs to be in the working state for a long time, and the pump life requirements are higher.
2. Inkjet needs stable pressure, which requires the pressure system to maintain stable pressure when working for a long time. It has high requirements on pump durability, stability and reliability.
3. Different ink components may contain additives that will decompose diaphragms, connectors or pipes and other parts of the pump, which puts a high requirement on the chemical resistance of the pump's materials.
4. Because the ink solvent is volatile and flammable, there are safety risks, and the pump is required to run without sparks and static electricity.
