A vacuum oil-filling machine is a device used to inject oil into machinery. It operates by using a vacuum pump to evacuate air from the machine's interior, creating negative pressure; this allows the lubricant to fully penetrate every corner of the internal space during injection, thereby achieving superior lubrication. Additionally, the vacuum extraction process removes impurities and moisture from the machine, ensuring the purity and stability of the lubricant and further enhancing lubrication performance.
Although these machines are highly effective at oil injection, the lubricant level within the machine will gradually decrease over time, necessitating periodic replenishment. The machine achieves this replenishment through a specially designed oil reservoir and piping system, allowing oil to be added without disrupting the machine's lubrication process.
