Technical field
The utility model relates to a kind of gas and oil separating plant, particularly a kind of oil gas pre-separate device of diesel engine.
Background technique
At present, more and more higher along with development of diesel and environmental protection requirement to the separating power requirement that diesel engine oil gas separates, and generally only designed single gas and oil separating plant in the prior art, Oil-gas Separation efficient is lower.For diesel engine provides a kind of oil gas pre-separate device that makes the diesel engine that Oil-gas Separation efficient is high and simple in structure, become and be badly in need of the technical problem that solves in the prior art.It is very important that suitable oil gas pre-separate device is set before deaerator for this reason, can effectively guarantee final oil gas separation.
The model utility content
The utility model is in order to overcome defective in the above-mentioned prior art, can to make the separating effect of oil gas better by the oil gas pre-separate device that increases vortex type pre-separation and mazy type deflector structure.
A kind of oil gas pre-separate device of the present utility model, be located in the gas channel of valve mechanism cover, gas channel is surrounded by valve mechanism cover and resuscitation apparatus cover plate and forms, and gas channel one side is established lubricating cup, establish the vortex type guide plate in the lubricating cup, oil gas is formed the vortex type pre-separation by the vortex type guide plate; The gas channel opposite side sets out tracheae, and the oil return bend pipe is established in the corresponding position of resuscitation apparatus cover plate bottom, steam outlet pipe.
Wherein, in the gas channel, establish the mazy type guide plate between vortex type guide plate and the steam outlet pipe, the mazy type guide plate is to be positioned at the guide plate that the gas channel both sides are provided with at interval, forms the collision type pre-separation of oil gas in the passage.
Preferably, the vortex type guide plate is specially the three fan tangential flow guiding plates that along the circumferential direction evenly are provided with.
Preferably, the oil return bend pipe is the U type, is used for the trapped fuel after separating on the described resuscitation apparatus cover plate is back to diesel engine.
Compared with prior art, oil gas pre-separate device of the present utility model can realize the effect of oil composition (oil droplet) in effective pre-separation gas, and compact structure is simple by the acting in conjunction of vortex type guide plate and mazy type guide plate, installs easily.

Embodiment
Below in conjunction with accompanying drawing the utility model is elaborated:
Use for diesel engine oil gas pre-separate device of the present utility model comprises parts such as valve mechanism cover pad 1, valve mechanism cover 2, resuscitation apparatus cover plate 3, first bolt 4, bullet pad 5, second bolt 6, oil return bend pipe 7, lubricating cup 8, steam outlet pipe 9.Valve mechanism cover 2 is connected fastening with the cylinder head of diesel engine by second bolt 6, and seal by valve mechanism cover pad 1, prevents that oil gas from leaking.The resuscitation apparatus cover plate is connected fastening with valve mechanism cover 2 by first bolt 4 and bullet pad 5, oil return bend pipe 7 is welded on the resuscitation apparatus cover plate 3, and lubricating cup 8 is welded on the resuscitation apparatus cover plate 3.The top of valve mechanism cover 2 is provided with the oil gas pre-separate device.
The oil gas pre-separate device is located in the gas channel of valve mechanism cover, and gas channel is shown in Fig. 3, Fig. 6 arrow, and this gas channel is mainly surrounded by valve mechanism cover 2 and resuscitation apparatus cover plate 3 and forms.Side at gas channel is established lubricating cup 8, establishes the vortex type guide plate in the lubricating cup, as shown in Figure 6.In the present embodiment, the three fan tangential flow guiding plates that this vortex type guide plate along the circumferential direction evenly is provided with can certainly adopt other structural types, as long as can form whirlwind.Can form the vortex type pre-separation to oil gas by this vortex type guide plate; The opposite side of gas channel sets out tracheae 9, and the oil return bend pipe 7 of U type is established in the corresponding position (as shown in Figure 4) of resuscitation apparatus cover plate bottom, steam outlet pipe, the trapped fuel of separating on the resuscitation apparatus cover plate 3 can be back to diesel engine.
In addition, in gas channel, between vortex type guide plate and the steam outlet pipe 9, establish the mazy type guide plate, in the present embodiment, this mazy type guide plate is to be positioned at the guide plate (as shown in Figure 6) that the gas channel both sides are provided with at interval, forms the collision type pre-separation of oil gas in the passage.
Simply introduce the pre-separation process of oil gas below: the oil-containing gases that is come by the diesel engine cylinder head cover bottom forms earlier the vortex type separation through the vortex type guide plate in the lubricating cup 8, carrying out collision type through the mazy type flow guide structure in the cylinder head cover 2 again separates, separate the outside of the clean gas in back by steam outlet pipe 9 guiding diesel engines, the mazy type guide functions flows back to diesel engine at the long-pending oil of resuscitation apparatus cover plate by oil return bend pipe 7 in the cylinder head cover.
The utility model oil gas preseparating structure can reach the effect of oil composition (oil droplet) in effective pre-separation gas, and compact structure is simple by the acting in conjunction of vortex type guide plate and mazy type guide plate, installs easily.
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
