Description
Technical field
The utility model relates to a kind of motor car engine air-strainer, and its filter core belongs to parallel-connection structure.
Background technique
The big more horsepower of motor that requires of the load-carrying of automobile is big more, and the air inflow of motor is also just big more, and air inflow is big more, and the resistance that air-strainer produces is also just big more.According to traditional design method, increase the main diameter that charge flow rate just must increase air-strainer.Because the restriction of vehicle complete vehicle topology layout and gas handling system resistance, the rated flow of mass flow air filter cleaner is generally at 1800m at present
3Below/the h.How increasing filter area and throughput under the situation of the main diameter that does not increase air-strainer is the current problem that needs solution.
The model utility content
The purpose of this utility model provides a kind of air-strainer, in order to solve the problem that is difficult to increase filter area and throughput under the existing structure situation.
For achieving the above object, scheme of the present utility model is: a kind of air-strainer, comprise housing, case top offers the plural filter cleaner suction port that communicates with enclosure interior, described housing one side offers the filter cleaner relief opening, be provided with upper and lower plural cylindrical filter core arranged side by side in the housing, the side face of filter core is towards the filter cleaner suction port, and the end face of filter core is towards the filter cleaner relief opening.
The utility model has adopted many filter cores parallel-connection structure, has increased filter area and does not increase main diameter, also the part of automobile free time is used, and has increased whole height, can not only increase air inflow, can also reduce flow resistance.
All correspondence is provided with a strainer on described each filter cleaner suction port, and the air outlet of strainer links to each other by the tracheae of being located on the filter case with described filter cleaner suction port, and tracheae is provided with the larynx hoop that is used for fixing described strainer.Be set up in parallel about described each strainer.The air inlet side of described strainer is to outwardly, and strainer suction port end is provided with screen, and strainer comprises the coarse filtration tube that is communicated with described strainer air outlet, and coarse filtration tube upstream is provided with impeller, and the downstream is provided with the dust discharge valve.Described each filter core includes the safe filter core of outer field main filter core and internal layer, is provided with the interior lining panel that is fixed in described filter case inside between main filter core and the safe filter core.
Description of drawings
Fig. 1 is overall structure figure of the present utility model;
Fig. 2 is strainer configurations figure.
Embodiment
The utility model is described in more detail below in conjunction with accompanying drawing.The numbering title is as follows with effect among the figure: 1 strainer: elementary dedusting, the large granular impurity of draining; 2 main filter cores: the secondary filter assembly, the end-filtration device is responsible for impurity screening, for motor provides clean, safe air, makes motor that mill early can not take place; 3 safe filter cores: more during the change owner filter core, guarantee that impurity does not enter the downstream of filter cleaner; 4 bonnets: compress filter core, and be fixed on the filter case; 5 filter cases: main body, protection filter core; 6 interior lining panels: be fixed in filter case inside, for filter core provides the fixed position; 7 coarse filtration shells: the gas-entered passageway of gas; 8 screens: stop big dust, as leaf, the scraps of paper etc.; 9 impellers: primary filter, by the centrifugal force dust-separating; 10 coarse filtration tubes: steady air flow, with the dust guiding dust discharge valve of impeller separation; 11 dust discharge valves: the dust that impeller separates is discharged; 12 larynx hoops: strainer is fixed on the filter cleaner; 13 tracheaes are arranged on the filter case.
The two cartridge air filter cleaners of a kind of parallel connection as shown in Figure 1 are made of two strainers 1 on top and a twin-core filter cleaner of bottom.The twin-core filter cleaner comprises filter housing 5, and filter housing 5 outsides offer the filter cleaner relief opening, and inside is provided with upper and lower two cylindrical filter cores arranged side by side, and the side face of filter core is towards the filter cleaner suction port, and the end face of filter core is towards the filter cleaner relief opening.Each filter core includes the safe filter core 3 of outer field main filter core 2 and internal layer, is provided with the interior lining panel 6 that is fixed in filter case 5 inside between main filter core 2 and the safe filter core 3.As shown in Figure 2, two strainers about 1 are set up in parallel, each strainer 1 top is provided with side direction suction port outwardly, the bottom is provided with the air outlet, each strainer 1 air outlet is connected by the tracheae on the filter case 5 13 with corresponding twin-core filter cleaner suction port, tracheae 13 is provided with larynx hoop 12, and two strainers 1 are fixed on the filter case 5; Strainer 1 suction port is provided with screen 8, and the below is communicated with the air outlet and is provided with coarse filtration tube 10, and coarse filtration tube 10 upstreams are equipped with impeller 9, and the downstream is provided with dust discharge valve 11.
The rated flow of twin-core filter cleaner is 2200m
3/ h, the flow resistance under its rated flow is no more than 3KPa, and the rough and careless efficient of strainer surpassed 80%, meets the requirement of JB/T 9755-1999 " internal-combustion engine papery cartridge air filter assembly technical specifications " fully.The twin-core filter cleaner does not increase main diameter, but the part of automobile free time is used, and has increased whole height, for Europe V, Europe VI vehicle gas emission device have been saved the space later on.This filter core parallel-connection structure disposes the first-selection that high-power starts up the car after must being.
Except the structure of above-mentioned pair of filter core, can also increase filter core quantity arranged side by side and filter cleaner suction port quantity, further increase and filter and air inflow; In actual the use, can not establish strainer yet and directly use filter cleaner.
The assembling of the two cartridge air filter cleaners of this parallel connection is divided into assembling of filter cleaner main body and strainer assembling.Filter cleaner main body installation step is as follows: interior lining panel 6 is fixed on the filter case 5, and two main filter cores 2 and safe filter core 3 are sealed and matched with interior lining panel 6 interference, and bonnet 4 assembles and compress the rear end cover of main filter core by bolt and filter case 5.The strainer installation step is as follows: after impeller 9 is put into coarse filtration tube 10 along slot, be assembled to coarse filtration shell 7(together slot equally also arranged) on, with tapping screw the three is coupled together, (there is the hangnail boss this position, prevents that screen 8 from coming off then screen 8 to be anchored to the square orifice place of coarse filtration shell 7; Have anti-dislocation projection to prevent screen 8 loading errors), at last dust discharge valve 11 is fixed to the dust discharge mouth of pipe of coarse filtration tube 1; At last two strainers 1 are fixed in the suction port place of filter case 5 by larynx hoop 12.
The working principle of the two cartridge air filter cleaners of this parallel connection is, atmosphere enters strainer 1 simultaneously from two screens 8, produces centrifugal force by impeller 9, and dust moves to the direction rotation of dust discharge valve 11 along the inwall of coarse filtration tube 10, is finally discharged by dust discharge valve 11.Clean gas is because light weight, and the negative-pressure sucking that produced by motor enters filter case 5, behind the fine filtering of gas through main filter core 2 and safe filter core 3, enters pressure-increasing machine by the exhaust pipe of twin-core filter cleaner.
