Abstract

The invention discloses a hydraulic pressure oil tank interior pressure control system and a mining dump vehicle. The hydraulic pressure oil tank interior pressure control system comprises a hydraulic pressure oil tank, a filter, an air inlet device and an air exhausting device, wherein the air inlet device and the air exhausting device are communicated in a one-way mode and communicated with the filter and the hydraulic pressure oil tank respectively. The communicated direction of the air inlet device is from the exterior of the hydraulic oil tank to the interior of the hydraulic oil tank, the air outside the hydraulic oil tank enters the hydraulic oil tank through the air inlet device after filtered by the filter. The communicated direction of the air exhausting device is from the interior of the hydraulic oil tank to the exterior of the hydraulic oil tank, and the air inside the hydraulic oil tank is exhausted out of the hydraulic oil tank through the air exhausting device after filtered by the filter. The hydraulic pressure oil tank interior pressure control system has the advantages of reducing the contact probability of hydraulic oil inside the hydraulic oil tank and the exterior air and improving the anti-pollution capacity of the hydraulic pressure oil tank.

Description

technical field [0001] The invention relates to a pressure control system, in particular to a pressure control system inside a hydraulic oil tank and a mining dump truck. Background technique [0002] Mining dump truck refers to a non-highway heavy dump truck used in open-pit mines to complete the tasks of rock and earth stripping and ore transportation. It is suitable for all kinds of mines and water conservancy projects; it has the characteristics of harsh environment, large dust and rock dust. Most of the hydraulic oil tanks of mining vehicles now use the method of continuously improving the filtration accuracy of the filter to control external pollution, which is used to minimize the entry of external impurities and dust into the oil tank during the operation of the hydraulic system; but this method not only needs to improve the accuracy of the filter Excessive investment in work cannot fundamentally solve the problem of external impurities and dust entering the fuel ta...
