What kind of oil should be used in a vacuum packaging machine?

[ArcherMarie]

Vacuum packaging machines require vacuum pump oil. Below is relevant information about vacuum pump oil: Introduction to vacuum pump oil: Vacuum pump oil refers to a specialized lubricant developed for vacuum pumps on vacuum equipment, which is divided into mineral oil and synthetic oil. Application scope of vacuum pump oil: Vacuum pump oil is suitable for use in reciprocating booster pumps, mechanical booster pumps, and oil-sealed mechanical vacuum pumps, among others. It can also be used in various diffusion vacuum pumps. It is recommended for vacuum pumps in fields such as crafts, ceramics, and chemistry. Performance characteristics of vacuum pump oil: Oxidation stability; rust and corrosion prevention; ability to quickly separate water entrained in the oil to achieve the required vacuum level. It has a low vapor pressure, preventing oil from flowing back and diffusing from the pump's inner cavity into the vacuum system, which could cause oil backflow.

I've found that refueling a vacuum packaging machine is not something to be taken lightly, as the machine needs proper lubrication to function correctly. I recommend using light machine oil or sewing machine oil, as these are standard choices that prevent complex substances from sticking to the components. If the machine is used for food packaging, it's best to opt for food-grade lubricating oil to ensure the sealing process doesn't contaminate the products. Before each refueling, clean the oil holes and check if the sealing rings have aged; otherwise, oil leakage may occur, affecting efficiency. Regular maintenance can extend the machine's lifespan—avoid using heavy oil or non-specialized oil, as these can easily cause parts to jam. For DIY operations at home, always refer to the manual first to see what oil the manufacturer recommends. Generally, refueling once a month is sufficient. If you notice increased noise or slower vacuuming, it might indicate a lack of oil or the wrong type being used.

I've been using a vacuum packaging machine for several years and know that improper oiling can cause trouble. Lightweight lubricating oil is sufficient, such as sewing machine oil or special vacuum pump oil, which is cheap and easy to find. For kitchen use, I prioritize food-grade oil to prevent contamination. Remember to turn off the power before adding oil to avoid electric shock, then use a small funnel to drip a few drops into the oil hole—don’t pour too much to avoid overflow. If you frequently package hot food, pay attention to the oil's high-temperature resistance. I’ve found that delayed oiling leads to component wear, weakens the machine’s vacuum suction, and results in poor sealing. Regularly check the oil level and keep it clean, and the machine will work smoothly.

Adding oil to a vacuum packaging machine isn't difficult. I recommend using light machine oil or food-grade lubricant for simplicity and efficiency. First, clean the oil port, then add a small amount as per instructions—avoid using regular motor oil. This helps prevent malfunctions.

From an economic perspective, choosing the right oil for vacuum packaging machines can save you money. For example, light machine oil or sewing machine oil offers great cost performance, extends the machine's lifespan, and reduces maintenance. Avoid using expensive specialized oils unless absolutely necessary. Always check the user manual before adding oil to prevent waste and potential damage to the machine. Regular maintenance helps avoid unnecessary expenses.
