Description

technical field [0001] The invention relates to the technical field of engine fuel filters, in particular to a constant temperature electromagnetic purification assembly and a constant temperature electromagnetic purification filter. Background technique [0002] According to the standard provisions of my country's diesel engine GB / T18297-2001 performance test method, the economic use indicators, power performance indicators, emission indicators, cold start indicators and service life of diesel engines and various diesel combustion equipment are all the same as those of diesel engines in use. (especially diesel oil with high cetane number) temperature index, microscopic quality index and purity index have extremely important relationship. According to the definition of my country's diesel oil quality standard GB / T19147-2003, it can be known that the temperature index, microscopic quality index and purity index of each grade of diesel oil in use are closely related to the ambi...

Problems solved by technology

The thermal filter has the following disadvantages: (1) The diameter of the inner hole of the hollow bolt connecting the filter fixing seat and the filter element is generally in the range of 8 to 13 mm, and the maximum diesel flow through it can only meet the work of a 65Kw to 360Kw diesel engine. If necessary, a magnetizing purification device is installed in the hole, which obviously reduces the output aperture, increases the resistance, and reduces the output flow, which obviously cannot meet the supply of dyes required for the diesel engine to work; (2) The magnetizer and mandrel are installed on the steel pipe In general, the existing magnetizers generally use permanent magnets, which are not resistant to high temperatures, especially not suitable for environments with large temperature contrasts. Therefore, if the magnetizers are sealed in a thermal filter, the low-temperature diesel will be heated rapidly, which will cause permanent magnets to If the magnetism is lost, the magnetizer will also lose its purification function; (3) Even if the magnetization heating device can be used, as the amount of adsorbed impurities continues to increase, after a certain period of time, the inner hole of the hollow bolt connecting the fixing seat and the filter element will be blocked. ; (4) When the filter is working, diesel oil enters the inner tank of the filter element through the fine filter holes on the filter element, and then outputs through the inner hole of the hollow bolt connected to the filter element through the fixing seat, and is used for engine jet combustion, while the core rod in the patent Installed in the inner tank of the filter element, the heat released by the mandrel cannot heat the diesel oil outside the filter element, resulting in the oil wax grains precipitated by the diesel oil at low temperature being trapped on the surface of the filter element and blocking the fine filter holes, which cannot prevent the low temperature from causing Difficulties in use caused by condensation of diesel oil; (5) The surface temperature of the metal electric heating mandrel is high, which can easily cause coking of oil molecules and reduce the thermal efficiency of combustion
