With the development of technology, one-way pneumatic diaphragm pumps in the printing industry is also more and more widely used as an essential part of the ink circulation device. One-way pneumatic diaphragm pump in the printing industry in the United States, Japan, Germany, Italy, the printing machinery are equipped with this pneumatic pumping device. Cartons and plastic printing machines in our country have been equipped with one-way pneumatic diaphragm pumps since the mid-1990s to replace electric pumps that are prone to sparks during the work and are prone to bubbles of ink. The one-way pneumatic diaphragm pump has the characteristics of safety, energy saving, high efficiency and durability. Due to the use of compressed air as the driving force, no spark, static electricity or electromagnetic interference occurs in the working process and is suitable for flammable and explosive applications. Media flow according to the needs of the printing press, through the pump needle valve stepless adjustment. After the pump starts to work, the ink continuously reciprocates to prevent the ink in the ink tank from crusting, so as to improve the printing quality. The pump body and filter are made of alloy casting. All parts in the pump are made of high quality corrosion-resistant materials. The special diaphragm and corrosion-resistant ink tube are resistant to ester, ketone, benzene, alcohol and other solvents. The working principle of the one-way pneumatic diaphragm pump: under the action of compressed air, the reciprocating motion of the air-chamber auxiliary mechanism in the pump drives the diaphragm to compress and compress the medium (such as ink, glue, solvent, etc.) Extraction, play the purpose of transporting media.
