Abstract
The invention relates to a cascade combined type coarse and fine granule grading filter cartridge and a combination method thereof, which aim to overcome the defect that a single-stage filter cartridge which is universally used is easy to block and short in duration time of designed overflowing capacity in the prior art. The surface of the single-stage filter cartridge is adhered by various impurity granules of different sizes in oil liquid easily and quickly, so that the oil passing capacity of the single-stage filter cartridge is reduced; and if the condition is developed to a certain degree, users are forced to shut down a machine and replace the filter cartridge to prevent an oil pump from being damaged by gas etching due to insufficient oil absorption, or oil return resistance is increased to improve the energy consumption of a system or an oil return check valve is opened to make oil return to an oil tank directly. In the cascade combined type coarse and fine granule grading filter cartridge, a primary filter cartridge consists of a filter screen, wherein the filter screen is used for filtering larger impurity granules; and a secondary filter cartridge is a fine filter cartridge for ensuring the cleanness of the system. A coarse filter cartridge filters the larger impurity granules, so the oil filter capacity and the service life of the fine filter cartridge are ensured effectively. The installation size of the filter cartridge is the same as that of the conventional accessory, and the cost of the filter cartridge is close to that of the conventional accessory, so the cascade combined type coarse and fine granule grading filter cartridge is an effective substitute product of the conventional filter cartridge.
Description
One, technical field:
The present invention relates to the filter core of a kind of hydraulic system with oil purifier.The hydraulic system that is particularly useful for the high cleanliness requirement is used fuel filter element.Also be applicable to the filter core that other various fluid filter systems are used.
Two, the state of the art:
Hydraulic Power Transmission System has been adopted in modern various machinery and heavy equipment widely.In all kinds of Hydraulic Power Transmission Systems for the performance reliability and working life of the various hydraulic element in the protective system effectively; Must filter be set at the return opening of the inlet port of hydraulic-pressure pump or system and come the various impurity particles in the filtering fuel tank fluid neutralized system, guarantee the turbidity test of system's inner fluid.
Fuel filter element technology in the present all kinds of hydraulic system all is the one-level filter core, the different just difference of the filter precision grade of filter core.The filter type of this single-stage filter core can guarantee the requirement of system to the filtering traffic and the turbidity test of fluid at the use initial stage; But prolongation along with service time; Various impurity particles not of uniform size can promptly stick to the surface of filter core in the fluid, make it cross oily ability and greatly reduce.This situation develops into certain degree, or forces the user to shut down more renew cartridge, otherwise can cause the oil pump oil suction not enough, produces cavitation erosion and damages oil pump; The oil return resistance increases, and increases the energy consumption of system or open the direct oil return oil purifier of return check valve to lose efficacy.These several kinds of situations reality use the direct result produced be main oil pump and element early stage damage or control fails and filter core replacing frequently.
Three, goal of the invention and solution:
The object of the invention is exactly to easy a kind of series mould assembly thickness gradation filter core and the combined method thereof of stopping up and designing oily ability endurance weak point and develop of existing single-stage filter core.The first filter level that is connected on the Combination filter element is made up of coarse filter element, by the bigger impurity particle of its filtering; Secondary filter core is only the fine filtering core into guaranteeing that system's turbidity test require.Since the coarse filter element filtering bigger impurity particle, the bur on the fine filtering core has only stayed less impurity particle, the speed of being stopped up cartridge surface by their greatly lowers, its oil strain ability with obtained assurance effectively working life.The two-stage filter core of this thickness Combination filter element is installed in series on same skeleton, and its boundary dimension and installation method are all with former identical with the single-stage filter core.
Solution of the present invention is: series mould assembly thickness gradation filter core is combined by skeleton 1, fine filtering core 2, coarse filter element 3, and coarse filter element 3 all is fixed on the skeleton 1 with fine filtering core 2.Different is: this Combination filter element divides internal-suction type and outer suction formula: the coarse filtration level of internal-suction type filter core is installed on the cylindrical of Combination filter element; The coarse filtration level of outer suction formula Combination filter element then is installed in the endoporus of Combination filter element.
Classified filtering of the present invention is compared with existing single-stage filtering technique; Because thickness impurity is by classified filtering; The oil filling capacity and the working life of filter core have been promoted effectively; The more former single-stage filter core of its cost of production increases few, and installation is identical with it with method for using, is the upgrading regeneration product of single-stage filter core.
Four, description of drawings:
Accompanying drawing 1 is the structural drawing of internal-suction type Combination filter element of the present invention.
Accompanying drawing 2 is structural drawing of outer suction formula Combination filter element of the present invention.
Five, mode of execution:
Embodiment of the present invention is: when starting oil pump, the interior or intrasystem fluid of fuel tank must be earlier after coarse filter element 3 filterings be coarser than the particle of 1-2 grade of fine filtering core, and the fine filtering core 2 of could and then flowing through filters, and is inhaled into oil pump or flows back to fuel tank.
