Abstract
The utility model provides a heat dissipation device for the hydraulic oil of an excavator. The heat dissipation device comprises a cooling fan, a fixed base, a housing, a fan shaft, a shaft sleeve, a connecting plate and a bearing sleeve, wherein the fixed base is fixed on one side of the housing and welded on the housing; a shaft hole is formed in the middle of the housing; the fan shaft penetrates through the shaft hole formed in the middle of the housing; the fan shaft is connected with the housing through the bearing sleeve; the cooling fan is mounted at the end, inside the housing , of the fan shaft, and mounted on the connecting plate through retaining screws; the connecting plate is fixed on the fan shaft; the shaft sleeve is mounted at the end, outside the housing, of the fan shaft; the shaft sleeve is connected with a driving motor. According to the utility model, the heat dissipation device is novel in structure, long in service life, easy to manufacture and low in utilization cost; in addition, the temperature of the hydraulic oil can be controlled finely to enable a hydraulic system to work stably for a long time, so that the service life of the hydraulic system is prolonged, and the production cost is reduced.
Description
Technical field
The utility model relates to heat sink technology field, is specially a kind of excavator hydraulic oil heat abstractor.
Background technology
Excavator is a kind of of engineering machinery, is widely used in the engineering fields such as building, road, mine, and Main Function is to carry out digging operation; The shape assumption diagram of the excavator of prior art, as shown in the figure, the working portion of excavator, mainly comprise scraper bowl, dipper and swing arm, and these workpieces all promotes by hydraulic jack.Because excavator often needs the work of long-time high power consumption, so hydraulic system need to be carried out good heat radiation.The hydraulic system of existing excavator, motor provides power for oil pump, oil pump offers each hydraulic jack by the hydraulic oil in hydraulic oil container, used hydraulic oil need to be back in hydraulic oil container, to the heat radiation of hydraulic system, is wherein mainly that hydraulic oil radiator by being arranged on oil return circuit is realized.
Generally, hydraulic oil radiator is a water tank, has full of twists and turns hydraulic oil path in casing, makes flow through hydraulic oil and the water tank generation interchange of heat of path, thereby reduces the temperature of hydraulic oil.Oil-in at hydraulic oil radiator is provided with pressure valve, and when pressure is greater than its threshold value, pressure valve is opened, and allows hydraulic oil to enter hydraulic oil radiator., so prior art only limited minimum oil pressure, do not limit MTP, when hydraulic fluid pressure is larger, can cause the damage of hydraulic oil radiator.Therefore, how effectively to protect hydraulic oil radiator to remain problem to be solved.
Utility model content
