Maintenance method of fire-resistant oil filter

It can regenerate and purify deteriorated fire-resistant oil, and effectively remove acid, pigment, gas, moisture and impurities in phosphate fire-resistant oil. It uses materials compatible with fire-resistant oil and oil purification technologies such as vacuum dehydration, multi-stage precision filtration, and new adsorbent deacidification to effectively ensure that the filtered fire-resistant oil meets the qualified indicators.

The maintenance points of fire-resistant oil are:

1. Dry the vacuum pump oil regularly to remove water from the vacuum pump oil. At this time, close the vacuum valve and start the vacuum pump for 30 minutes.

2. Check the vacuum pump oil level. When turbidity occurs, the special vacuum pump oil should be replaced in time.

3. Check the connection of the inlet and outlet oil pipes.

4. During operation, when the pressure difference between pressure gauge 1 and pressure gauge 2 exceeds 100 KPa, the differential pressure alarm will sound, or the filter element will be replaced according to the actual use.

5. When the pressure difference between pressure gauge 2 and pressure gauge 3 exceeds 100 Kpa, clean or ｒｅｐｌａｃｅ the vacuum diffuser core according to the actual use.

6. When the pressure difference between pressure gauge 3 and pressure gauge 4 exceeds 100 Kpa, the differential pressure alarm will sound, or the core will be cleaned or replaced according to the actual usage.
