Abstract
The utility model discloses dump truck hydraulic oil container air-breather, comprise hydraulic oil container (3), the integrated lid of hydraulic oil container, namely the hydraulic fuel tank cap (1) containing air filter (2), it is characterized in that: with the hydraulic oil casing of the integrated lid opposite position of hydraulic oil container above set up an independently air-breather, this air-breather comprises and communicating and all-in-one-piece breathing pipe (4) affixed with hydraulic oil container with hydraulic oil casing, breathing pipe top is fixedly connected with dust guard holder (5) by screw thread, dust guard holder top is provided with through hole, air filting material layer (6) is filled with between dust-proof cover (7) inner side and dust guard holder.The utility model Throughput is large, even.Preparation process is simple, and topology layout is reasonable, does not increase manufacture cost, effectively solve the hypoventilation because of hydraulic oil container, the hydraulic oil container inside occurred produces negative pressure or back pressure, makes hydraulic pressure execution device not smooth for shortage of oil, oil extraction, the phenomenons such as hydraulic oil container vibrations.
Description
Technical field
The utility model relates to a kind of dump truck hydraulic fittings technical field, especially dump truck hydraulic oil container air-breather.
Background technique
The hydraulic oil container of heavy dump truck is arranged on operator cabin vehicle frame below, it is the oil-stocking equipment in hydraulic executing system, innage is between 56-78 rises, hydraulic oil container air-breather is arranged on the top of hydraulic oil container, Main Function is in order to anti-hydraulic pressure execution device is in the operation of oil suction, oil extraction, negative pressure or back pressure are produced to hydraulic oil container inside, make hydraulic pressure execution device not smooth for shortage of oil, oil extraction, cause hydraulic pressure execution device to shake, flexible dumb, the faults such as hydraulic oil container distortion produce.Existing hydraulic oil container air-breather adopts the integrated ventilating mode of hydraulic fuel tank cap, vent only has φ 6mm, when the moment oil suction of hydraulic pressure execution device, oil drain quantity reach 5-10 liter/second, the hypoventilation of hydraulic oil container vent, very easily occur that hydraulic oil container inside produces negative pressure or back pressure, make hydraulic pressure execution device for the not smooth phenomenon of shortage of oil, oil extraction, cause hydraulic pressure execution device to shake, flexible dumb, the faults such as hydraulic oil container distortion produce.
Model utility content
The purpose of this utility model is to overcome prior art shortcoming, provides one hydraulic oil container can be prevented inner because hypoventilation produces negative pressure or back pressure, makes hydraulic pressure execution device for the dump truck hydraulic oil container air-breather of the not smooth phenomenon of shortage of oil, oil extraction.The purpose of this utility model is realized by following technical proposals, the utility model comprises hydraulic oil container, the integrated lid of hydraulic oil container, namely the hydraulic fuel tank cap containing air filter, it is characterized in that: with the hydraulic oil casing of the integrated lid opposite position of hydraulic oil container above set up an independently air-breather, this air-breather comprises and communicating and all-in-one-piece breathing pipe affixed with hydraulic oil container with hydraulic oil casing, breathing pipe top is fixedly connected with dust guard holder by screw thread, dust guard holder top is provided with through hole, air filting material layer is filled with inside dust-proof cover and between dust guard holder.
Adopt the utility model scheme, preparation process is simple, and the own wt of hydraulic oil container air-breather only has 0.5kg, and fabricating cost is at about 3 yuan, and available remaining material secondary utilizes, and has saved resource.Simultaneously the utility model device, is dispersed in the position near hydraulic oil container two ends with the position of hydraulic fuel tank cap, the large and uniform balance of Throughput, avoids hydraulic pressure execution device for the not smooth problem of shortage of oil, oil extraction, effectively prevents hydraulic oil container seismism.From above-mentioned situation, the purpose of this utility model can realize completely.
Accompanying drawing explanation
Fig. 1 is the utility model increase independently hydraulic oil container air-breather.
Embodiment
The utility model is described in further detail in conjunction with the embodiments with reference to the accompanying drawings below:
Embodiment as shown in Figure 1, the utility model comprises hydraulic oil container 3, the integrated lid of hydraulic oil container, namely the hydraulic fuel tank cap 1 containing air filter 2, to it is characterized in that: with the hydraulic oil casing of the integrated lid opposite position of hydraulic oil container above set up an independently air-breather, this air-breather comprises and communicating and all-in-one-piece breathing pipe 4 affixed with hydraulic oil container with hydraulic oil casing, breathing pipe top is fixedly connected with dust guard holder 5 by screw thread, dust guard holder top is provided with through hole, is filled with air filting material layer 6 inside dust-proof cover 7 and between dust guard holder.
