Abstract
The utility model discloses the dilution system of a kind of filter capability test, comprise fuel tank, primary polishing filters and secondary purification filtrator, injection pump, extraction pump and dilution system, described fuel tank is the first fuel tank and the second fuel tank, extraction pump and secondary purification filtrator is provided with successively on the pipeline that dilution system exports between the first fuel tank, to the pipeline the import of described dilution system, injection pump and primary polishing filters is provided with successively from the second fuel tank, pipeline from the first fuel tank to the second fuel tank is provided with successively ebullator and the filtering accuracy high-precision filter higher than the filtering accuracy of described primary polishing filters and secondary purification filtrator.The remarkable advantage that the accuracy requirement that the utility model has primary filter and secondary filter easily meets.
Description
Technical field:
The utility model relates to a kind of detection technique, the dilution system of particularly a kind of filter capability test.
Background technology:
The dilution system of existing metre filter performance test is made up of (see accompanying drawing 1) injection pump primary filter, dilution system, extraction pump, secondary purification filtrator and fuel tank.This dilution system is high when the filtering degree of secondary filter and primary filter, easily causes the top hole pressure of extraction pump to increase; When the filtering accuracy of above-mentioned two-stage filter is low, then can not ensure again the requirement of the cleanliness of fluid in fuel tank, thus, to the selection and comparison difficulty of two-stage filter precision.
Summary of the invention:
The utility model object is to provide a kind of primary depuration filter and secondary purification Filter Precision requires the dilution system that low a kind of filter capability is tested.
Realizing the technical solution of the utility model is, a kind of dilution system of filter capability test, comprise fuel tank, primary polishing filters and secondary purification filtrator, injection pump, extraction pump and dilution system, it is characterized in that: described fuel tank is the first fuel tank and the second fuel tank, extraction pump and secondary purification filtrator is provided with successively on the pipeline that dilution system exports between the first fuel tank, to the pipeline the import of described dilution system, injection pump and primary polishing filters is provided with successively from the second fuel tank, pipeline from the first fuel tank to the second fuel tank is provided with successively ebullator and the filtering accuracy high-precision filter higher than the filtering accuracy of described primary polishing filters and secondary purification filtrator.
The remarkable advantage that the accuracy requirement that the utility model has primary filter and secondary filter compared with the prior art easily meets.
Accompanying drawing illustrates:
Fig. 1 is prior art systems structural representation; Fig. 2 is system schematic of the present utility model.
Embodiment:
In order to overcome the above-mentioned defect that prior art exists, the utility model adopts following technical proposals,
Pipeline between the outlet of dilution system and the first fuel tank 1 is provided with extraction pump 7 secondary purification filtrator 8 and is located on the pipeline between described discharge delivery side of pump and the first fuel tank, be located on the pipeline between the second fuel tank 2 outside the first fuel tank and the import of dilution system and be provided with injection pump and primary depuration filter 6 from the second fuel tank successively to dilution system, the pipeline from the first fuel tank to the second fuel tank is provided with successively ebullator 3 and high-precision filter 4.
Principle of work of the present utility model is, the filtering accuracy of above-mentioned high-precision filter 4 should higher than elementary and precision that is secondary purification filtrator; From the first clean fuel tank, after high-precision filter 4, enter the fluid of the second fuel tank more clean compared with the oil in the first fuel tank for fluid out, get back in the first fuel tank from the fluid the second fuel tank through primary polishing filters and dilution system and secondary purification filtrator, namely the cleanliness of this fluid can not reduce.Thus, to the non-constant width of the accuracy requirement of firsts and seconds polishing filter, hold very much and select.
Claims (1)
