Pneumatic intermittent circulation lubrication device

Friction pairs in various types of machinery often require intermittent lubrication, such as sliding sleeves and guide rods in the film-drawing mechanism of a vertical bag-making machine. The sliding sleeve is linearly reciprocated on the guiding rod by the crank and the connecting rod, and the fre ......

Make GM technology safer

Most of the soybeans on the market today are genetically modified soybeans, which have been transferred to a certain kind of genes, which makes soybeans resistant to herbicides or pests. This facilitates field management, reduces the use of pesticides, and reduces production costs. It also protec ......
