Charge type coalescence separation oil filter

Abstract

The invention discloses a charge type coalescing-separating oil filter, which is characterized by comprising a coarse filter, an oil-pump motor group, a prefilter, an electrostatic oil filtering mechanism, a collector, a coalescing-separating mechanism and an electric control box which are arranged in sequence along an oil inlet, wherein the electrostatic oil filtering mechanism is provided with a positive electrode and a negative electrode; and the coalescing-separating mechanism is provided with a coalescing filter core and a separating filter core. The charge type coalescing-separating oil filter disclosed by the invention has the beneficial effects that the physical and chemical properties of oil liquid are not changed, and the service life of the oil liquid can be prolonged; by loading of positive and negative electrostatic charges to the micro particles, the micro particles are gathered into larger catchable and filterable particles, and are filtered by the collector; by loading of positive and negative electrostatic charges to a trace of soluble water in oil, the soluble water can be gathered into larger filterable water drops, and are filtered when passing the coalescing filter core and the separating filter core, so that the purpose of removing micro particles and the trace of soluble water which can not be removed in the prior art is achieved; and the coalescing filter core is hydrophilic, and the separating filter core is hydrophobic, so that the water can be effectively removed and the water removing efficiency is improved.

Description

technical field [0001] The invention relates to an oil filter, in particular to a charge type coalescence separation oil filter. Background technique [0002] The existence of water in the hydraulic lubrication system will cause the oil to oxidize, deteriorate the oil, reduce the thickness of the oil film, reduce the lubricity, cause the oil to denature and polymerize to form macromolecules, change the viscosity of the oil, form organic acids, and corrode metals The surface reduces or loses the dielectric strength of the oil; mechanical impurities and sludge will destroy the oil film, accelerate the wear of the equipment, block the valve core and filter, and cause equipment failure during operation. Therefore, it is necessary to remove the water and mechanical impurities in the oil to keep the oil in a very clean state, which can reduce the failure rate of the equipment and reduce the replacement of oil products. [0003] For traditional filtration and separation equipment,...

Problems solved by technology

[0003] For traditional filtration and separation equipment, it is particularly difficult to separate one of the liquids from the mixed liquid. The existing technology has many defects: the liquid with a moisture content greater than 5000ppm in the vacuum oil filter evaporates and condenses slowly, and the purification Low efficiency; while the coalescing separation oil filter cannot remove trace moisture and dissolved water in the oil
