Standard specification for vacuum pump oil filter element

‌The standard specifications of vacuum pump oil filter mainly include the following aspects :

Filtration accuracy : The filtration accuracy of the vacuum pump oil filter element is usually expressed in microns (μm), and the common accuracy range is from a few microns to several hundred microns. The high-precision filter element is suitable for vacuum pump equipment with high requirements for oil quality, which can effectively filter out small impurities, but the risk of blockage is high, and it needs to be replaced regularly; Medium precision filter is suitable for general industrial use, can filter out most impurities, long replacement cycle; Low precision filter element is suitable for occasions where the oil quality is not high, the filtration effect is general, but the price is low ‌.

Material : vacuum pump oil filter element material usually includes glass fiber filter paper, different sources of material price and quality are different. For example, German glass fiber filter paper is of higher quality but higher price, while Italian glass fiber filter paper is of lower price but lower quality ‌.

Technical parameters : The technical parameters of the vacuum pump oil filter element include high temperature resistance (≤100℃), high pressure resistance (can withstand the pressure difference of 2MPa), corrosion resistance, small volume and easy handling, large processing gas, small gas consumption during backblowing cleaning, small energy consumption and so on. In addition, the filtration efficiency of the filter element is usually above 99%, the initial pressure difference is less than 0.02Mpa, and the life of the filter element is between 5000 and 10000 hours ‌.

Replacement and maintenance : The replacement and maintenance of vacuum pump oil filter element needs to be determined according to the specific use. When the exhaust back pressure exceeds 0.6kgf or white fog is observed in the exhaust, the filter element needs to be replaced. In order to prevent dust and particulate matter in the pump oil from entering the pump chamber, some processes require a continuous filtration device while the pump is running. The pressure gauge on the filter can be used to monitor whether the filter element is blocked, and the filter element needs to be replaced or cleaned when the pressure rises ‌.

In summary, the standard specifications of the vacuum pump oil filter cover the filtration accuracy, material, technical parameters, replacement and maintenance, etc., to ensure that it can meet the working needs of the vacuum pump during use and extend the service life of the equipment.
