Description

Multifunctional mask respirator holder device with gas channel

Technical field

The invention belongs to engine accessory mechanical part, be specifically related to the mounting bracket device of a kind of Diesel engine respiratory organ.

Background technology

The harm mankind caused along with the aggravation of environmental pollution is also increasing, and various countries take measures to reduce disposal of pollutants one after another. Motor vehicle exhaust emission is one of important polluter, forces internal combustion engine industry that more advanced technology must be adopted to meet emission regulation demands. Along with more new techniques application on the engine such as waste gas recirculatioies (EGR), the structure making electromotor becomes complex, and parts also get more and more, and causes that machine shape strengthens, engine cabin assembly space seems not enough, and cost also can accordingly increase. For reducing machine shape size as far as possible, make complete machine structure compacter, it is necessary to electromotor peripheral element carries out reasonable Arrangement and optimization, reduce amount of parts as far as possible, accomplish that single-piece is multi-functional. Respiratory organ is parts indispensable on electromotor, is generally all arranged on electromotor periphery, so will cause that machine shape size increases, and therefore respiratory organ arranges that the unreasonable car load that will directly affect mates.

A kind of respiratory organ mounting bracket that the present invention proposes, except being used for installing respiratory organ, but also can install other parts, support have the gas channel vertically drilled through, and seals structure, make complete machine structure compacter, and machine shape is smaller.

Summary of the invention

It is an object of the invention to provide a kind of Multifunctional mask respirator support with gas channel, it is possible to make electromotor profile reach densification.

In order to realize this purpose, principles of the invention and structure be: with the Multifunctional mask respirator holder device of gas channel, including respiratory organ support, air inlet pipe, respiratory organ, stand type support, inlet pipe connection support, inlet suction port, gas inlet rubber tube, hoop, wire harness bracket, cushion rubber, crankcase and bolt etc. Respiratory organ support is arranged above with vertical channel hole, and the right flank of respiratory organ support is provided with hole, horizontal channel, and oil gas carries out 90 degree of turnings in the access opening of vertical and horizontal. Respiratory organ support is arranged on the boss of air inlet pipe side, and respiratory organ is secured by bolts on the installing hole at respiratory organ support right flank two ends. The front end of respiratory organ support is provided with stand type support, is provided with vertical boss after respiratory organ support vertical access opening, and hole, horizontal channel is connected with respiratory organ air inlet.

The structure of this respiratory organ support is entirely and is designed according to specific arrangement space, vertical channel in respiratory organ support and horizontal channel, makes oil gas realize 90 degree of turnings in very narrow space, makes respiratory organ press close to air inlet pipe to greatest extent. Compared with traditional steel pipe bending gas channel, this geometries shrink bending space, make machine shape width significantly reduce. The gas channel simultaneously vertically drilled through, is conducive to the machine oil steam in oil gas to beat in passage corner, condenses into lubricating oil and separate from fuel-air mixture, improve oil-gas separation efficiency.

Feature and the generation of the present invention provide the benefit that: respiratory organ support is entirely and designs according to specific arrangement space, simple and compact for structure, function is integrated, and machine shape is little. Respiratory organ support is simultaneously provided with wire harness bracket and the installation site of inlet pipe connection support, makes structure compacter. Vertical gas channel contributes to Oil-gas Separation, improves separation efficiency, and respiratory organ has oil return function simultaneously, decreases engine oil consumption, also reduces the pollution to air of machine oil and crankcase waste gas simultaneously.

Detailed description of the invention

Below in conjunction with accompanying drawing and by specific embodiment, the structural principle of the present invention is described further, but the content that the present invention contains is not limited to following embodiment.

With the Multifunctional mask respirator holder device of gas channel, its technical pattern is: respiratory organ support 1 is arranged above with vertical channel hole 2, and the right flank of respiratory organ support is provided with hole, horizontal channel 3, and oil gas carries out 90 degree of turnings in the access opening of vertical and horizontal. Respiratory organ support is arranged on the boss 4-1 of air inlet pipe 4 side, and namely this support is fastenedly connected with two screwed holes on air inlet pipe boss by bolt. Respiratory organ 5 is fixed on the installing hole at respiratory organ support right flank two ends by bolt 6. The front end of respiratory organ support is provided with stand type support 7, and wire harness bracket 14 is secured by bolts in stand type support. Being provided with vertical boss 8 after respiratory organ support vertical access opening, the hole, horizontal channel of respiratory organ side face is connected with respiratory organ air inlet 9, and access opening is sealed with respiratory organ air inlet by cushion rubber 16.

Inlet pipe connection support 10 is secured by bolts in vertical boss. Upper end, vertical channel hole is equipped with inlet suction port 11, and one end of gas inlet rubber tube 12 is anchored on inlet suction port by hoop 13, and the other end of gas inlet rubber tube is connected with the crankcase ventilation mouth of electromotor. In order to effectively alleviate engine body load-bearing, the side of respiratory organ support level access opening is provided with duplicate removal groove 15.

For four-cylinder diesel engine, respiratory organ support is formed by the casting of gray iron material, is arranged on the boss of air inlet pipe side by respiratory organ support by the bolt of two M10. The internal diameter in the oil gas vertical channel hole on respiratory organ support is �� 20mm. Having inlet suction port at vertical channel hole place by interference fit, inlet suction port is the steel pipe manufacturing of 2mm by wall thickness, and its lower end interference fit loads in access opening, uses sealant sealing. The internal diameter in hole, respiratory organ support right flank horizontal channel is �� 16mm, and aperture place is provided with O-ring seals groove and seals. Respiratory organ is arranged on the side of respiratory organ support by the bolt of two M8. The stand type support of respiratory organ support front end is provided with two M8 installing holes, with bolt, wire harness bracket is fixed. The vertical boss that respiratory organ support stretches out above is provided with the bolt hole of two M8, is used for installing fixing inlet pipe connection support.

During electromotor work, from the oil gas mixed air that engine crank case ventilation mouth is discharged, respirator interior is entered through gas inlet rubber tube, inlet suction port, vertical channel hole, respiratory organ air inlet is tangent with respiratory organ inner chamber, oil gas mixed air tangentially enters respiratory organ inner chamber, is formed along respiratory organ inwall and rotates, and oil gas mixed air is beaten under the influence of centrifugal force on respiratory organ inwall, make oil vapour condense into liquid, stay along inwall. Respirator interior has filter element 17, oil gas mixed air passes filter element from surrounding, oil gas mixed air is filtered separating by filter element, condenses and the machine oil separated converges in oil return opening 18 place bottom respiratory organ with liquid form under gravity, finally flow back in engine sump tank. The gas separated is discharged in air by the air vent 19 of respiratory organ top.

Multifunctional mask respirator holder device with gas channel is applied on 4102-CE4B diesel engine, and effect is very good.
