Description

Technical Field

[0001] The utility model belongs to the technical field of power oil monitoring and purification, and in particular relates to an intelligent fire-resistant oil processing device. Background Art

[0002] Phosphate ester fire-resistant oil is the main medium for transmitting energy and cooling the generator set. As the running time increases, the oil will inevitably deteriorate and deteriorate, accompanied by oil quality problems such as particle pollution and water pollution. The deterioration of oil is mainly manifested in unqualified volume resistivity; and the main reason for unqualified oil particle size is system wear and seal damage. At the same time, it is easy to cause free water inside the oil due to the influence of environmental humidity. Unqualified resistivity may cause servo valve corrosion, unqualified particles may cause servo valve jamming, and unqualified water content will damage the lubricating oil film, which will cause corrosion of metal parts of the lubrication system and make the additive function ineffective, and other serious consequences.

[0003] The oil used in equipment will deteriorate and become polluted due to the wear of the equipment system and poor sealing, so it is necessary to regenerate, dehydrate and filter the deteriorated and polluted oil. However, when the volume resistivity, particle size and water content of the oil exceed the standard, the monitoring results of the oil quality are not timely and accurate, which makes the oil quality treatment have obvious lag, which will cause damage to the oil-using equipment and increase the cost.

[0004] When the volume resistivity of oil exceeds the standard, the regeneration treatment method can be used to restore the volume resistivity. When the particle size exceeds the standard, the filtration treatment method can be used to purify the particulate matter in the oil. When the water content exceeds the standard, the dehydration purification method can be used to dehydrate the water in the oil. However, the current oil regeneration, filtration and dehydration methods are usually based on the results of on-site sampling and testing. The representativeness of the sampling and the sampling interval seriously affect the oil treatment efficiency. Usually, after the sampling test is qualified, the over-treatment method is used to continue the treatment for a period of time to ensure that the oil quality indicators are qualified. This method causes excessive consumption of consumables such as filter elements. Utility Model Content
