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 frequency is 20-50 times/min. In order to ensure smooth movement and prevent wear, a suitable amount of lubrication is 0.1 to 0.3 L/min. It is difficult to achieve the required oil supply by drip lubrication, and forced lubrication with oil pump type will cause excessive lubrication. The pneumatic intermittent circulation lubrication device can perform good intermittent automatic lubrication with the sliding sleeve reciprocating motion. 1. Working principle Pneumatic intermittent circulation lubrication device is shown in the figure. It consists of solenoid valve 1
