The interlayer space formed with the gas-permeable rod.The beneficial effect of generation is that this double cavity structure is by reducing air velocity and increase
The mode of residence time helps to reach preferably cooling condensation effect.
Further, the radiating sleeve outer surface is disposed with cooling fin.The beneficial effect of generation is the heat dissipation effect of radiating sleeve
It is strengthened, internal oil gas condensation effect is more preferable.
Preferably, the heat dissipation set upper side is removably connected with the internal top connection for being disposed with through-hole, under the radiating sleeve
End is removably connected with the internal lower contact for being disposed with through-hole.
Preferably, inside is disposed with the observation lid of through-hole and the lower contact is detachably connected, and the observation lid is arranged in
Gear-box opening communicates the cavity of gear-box with the cavity inside the condensing unit.
Preferably, the observation covers and is disposed with oil baffle.The beneficial effect of generation is can effectively prevent in gear-box
Lubricating oil splash enter condensing unit and Ventilated cap.
Preferably, being disposed with the particulate Si for adsorbing moisture in oil gas in airflow channel inside the Ventilated cap
Glue.The beneficial effect of generation is to adsorb to the moisture in gas, enters gear-box corrosion gear to prevent large quantity of moisture.
Preferably, being disposed with the molecular sieve for adsorbing moisture in oil gas in airflow channel inside the Ventilated cap.
The beneficial effect of generation is to adsorb to the moisture in gas, enters gear-box corrosion gear to prevent large quantity of moisture.
Preferably, the lower disposed in Ventilated cap interior air-flow channel has spongy layer.The beneficial effect of generation is sponge layer
On the other hand the particle of adsorption moisture can be supported not fall into gear-box with adsorption coagulation oil gas.
Preferably, the top in Ventilated cap interior air-flow channel is disposed with strainer.The beneficial effect of generation is that strainer can
Further filtering condensation is carried out to oil gas.
Compared with prior art, beneficial effects of the present invention:
1, solve the problems, such as that gear box venting structure is easy blocking.By increasing condensing unit and oil baffle, make to come from
After the oil gas of gear-box first obtains pretreatment in condensing unit, the content of lubricating oil is substantially reduced in oil gas, greatly reduces
The workload of Ventilated cap solves the problems, such as that Ventilated cap is easy blocking substantially.
2, ventilating structure has good economic effect and easy to maintain.Condensing unit is detachable, so that a kind of ventilative
Cap is matched by the condensing unit with different size can be applied to a variety of gear-boxes, in addition clean to the maintenance of condensing unit
It is very convenient, avoid financial burden caused by frequently replacement Ventilated cap.
