An armored vehicle closed oil tank ventilation device

Abstract

The invention discloses an armored vehicle closed type engine oil tank ventilation device which comprises an upper ventilation cavity 1, a lower ventilation cavity 2, a gas-oil mixture inlet 3 communicated with an engine oil tank, an air outlet 4 communicated with the external environment, and an oil return opening 5 communicated with a diesel engine. The upper ventilation cavity 1 is communicated with the air outlet 4, the bottom of the lower ventilation cavity 2 is communicated with the oil return opening 5, and the middle portion of the lower ventilation cavity 2 is communicated with the gas-oil mixture inlet 3; the upper ventilation cavity 1 is communicated with the lower ventilation cavity 2 through a steel plate 6 with holes; a layer of foam removing board 7 is arranged on the upper portion of the lower ventilation cavity 2 and an iron wire screen 8 is arranged between the foam removing board 7 and the steel plate 6 with the holes. The armored vehicle closed type engine oil tank ventilation device can solve the problem that due to the fact that the pressure of waste gas is high, the engine oil tank is deformed and cracked; the work intensity of a respirator of the diesel engine is reduced, the reliability and the safety of the operation of an armored vehicle are improved, and the armored vehicle closed type engine oil tank ventilation device has the advantages of being simple in structure, low in cost, high in universality and the like.

Description

technical field [0001] The invention belongs to the technical field of armored vehicle engine lubricating systems, and in particular relates to a ventilator for a closed oil tank of an armored vehicle. Background technique [0002] At present, the oil tanks used by armored vehicles are all closed oil tanks, and the oil tank itself has no ventilation measures, and the suction capacity of the diesel engine oil return pump is relatively strong, resulting in high exhaust gas pressure inside the oil tank, which is easy to cause deformation of the oil tank and cracking, and will increase the working pressure of the diesel engine's own respirator. In light cases, when the working pressure of the diesel engine's self-contained respirator increases, it will cause frequent oil leakage, and the sprayed lubricating oil will splash on the surrounding sensors, causing some sensors to fail, causing their wrong measurement and judgment, and causing driving problems. If the operator cannot ...

AI Technical Summary

Problems solved by technology

[0002] At present, the oil tanks used by armored vehicles are all closed oil tanks, and the oil tank itself has no ventilation measures, and the suction capacity of the diesel engine oil return pump is relatively strong, resulting in high exhaust gas pressure inside the oil tank, which is easy to cause deformation of the oil tank and cracking, while increasing the working pressure of the diesel engine's own breathing apparatus

In light cases, when the working pressure of the diesel engine's self-contained respirator increases, it will cause frequent oil leakage, and the sprayed lubricating oil will splash on the surrounding sensors, causing some sensors to fail, causing their wrong measurement and judgment, and causing driving problems. If the operator cannot correctly determine the condition of the vehicle, it is easy to drive the vehicle "sick" and perform unnecessary maintenance on the vehicle in good technical condition; in addition, if the lubricating oil splashes on the exhaust pipe of the diesel engine, it is easy to cause the engine compartment to catch fire , seriously affecting the normal use of the vehicle chassis

In severe cases, it will cause deformation and cracking of the oil tank, resulting in the failure of the lubrication system of the armored vehicle, which will inevitably cause the diesel engine to fail to operate normally, and further cause damage to the diesel engine

[0003] If the suction capacity of the oil return pump is reduced, it cannot meet the timely oil return requirements of the dry oil pan under special working conditions such as vehicle pitch and roll, which is also very unfavorable to the normal use of the vehicle.
