The hydraulic system media oil cooling device can save equipment cost and use and maintenance cost.
Description
(1) technical field
The utility model relates to a kind of hydraulic system's media oil cooler.Belong to the hydraulic system technical field.
(2) background technique
At present, the hydraulic system's media oil cooling but, usually design of Hydraulic System person adorns a circulation cooling oil pump and carries out cooling medium fluid at the hydraulic reservoir place, as shown in Figure 1.The leakage high temperature oil of main oil pump, the overflow high temp oil of relief valve are cooled off by the circulation cooling oil pump without the direct oil-feed tank of cooling.So not only increase the oil circulating pump equipment cost, oil circulating pump moves the required electric energy and the maintenance cost of equipment when also increasing the hydraulic system use.
(3) summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of hydraulic system's media oil cooler of saving equipment cost and working service cost is provided.
The purpose of this utility model is achieved in that a kind of hydraulic system's media oil cooler, comprise main oil pump, relief valve, first cooler, second cooler, oil pump drain pipeline, relief valve overflow oil pipe, system oil supply bar, system oil return house steward and fuel tank, described main oil pump has two, two main oil pumps to be arranged in parallel, the oil outlet connecting system oil supply bar of two main oil pumps, the system oil return house steward inserts first cooler, and the oil outlet of first cooler inserts fuel tank; The leakage high temperature oil outlet of two main oil pumps inserts the oil pump drain pipeline, and the overflow high temp oil export of relief valve inserts relief valve overflow oil pipe, and oil pump drain pipeline and relief valve overflow oil pipe insert second cooler, and the oil outlet of second cooler inserts fuel tank.
System oil return house steward's high temperature oil is oil-feed tank after the cooling of first cooler, the leakage high temperature oil of main oil pump, the overflow high temp oil of relief valve oil-feed tank after the cooling of second cooler.
The beneficial effects of the utility model are:
At the hydraulic system performance evaluation, the medium oil liquid temperature of hydraulic system raises and caused by two factors: one, hydraulic system oil hydraulic pump, control valve etc. itself cause hydraulic oil to rise.Two, the ambient temperature radiation causes hydraulic system oil cylinder and hydraulic line inner fluid temperature to rise, by analyzing the utility model these two parts are cooled off, hydraulic system oil temperature just can effectively be controlled, therefore the circulation cooling oil pump be can delete, equipment cost and working service cost saved.
(4) description of drawings
Fig. 1 is the structural representation of hydraulic system's media oil cooler in the past.
Fig. 2 is the structural representation of the utility model hydraulic system's media oil cooler.
Reference character among the figure:
Main oil pump 1, relief valve 2, first cooler 3, second cooler 4, circulation cooling oil pump 5, oil pump drain pipeline 6, relief valve overflow oil pipe 7, circulating cooling system 8, fuel tank 9, system oil supply bar P, system oil return house steward T.
(5) embodiment
Referring to Fig. 2, Fig. 2 is the structural representation of the utility model hydraulic system's media oil cooler.As seen from Figure 2, the utility model hydraulic system's media oil cooler is made up of main oil pump 1, relief valve 2, first cooler 3, second cooler 4, oil pump drain pipeline 6, relief valve overflow oil pipe 7, system oil supply bar P, system oil return house steward T and fuel tank 9.Main oil pump 1 has two, two main oil pumps 1 to be arranged in parallel, and the oil outlet that the oil outlet connecting system oil supply bar P of two main oil pumps 1, system oil return house steward T insert first cooler, 3, the first coolers 3 inserts fuel tank 9; The leakage high temperature oil outlet of two main oil pumps 1 inserts oil pump drain pipeline 6, the overflow high temp oil export of relief valve 2 inserts relief valve overflow oil pipe 7, the oil outlet that oil pump drain pipeline 6 and relief valve overflow oil pipe 7 insert second cooler, 4, the second coolers 4 inserts fuel tank 9.
