Abstract
The utility model discloses a hydraulic oil cooling device applicable to small loaders below one ton, which pertains to the field of engineering mechanical equipment technology. A hydraulic oil cooling device for small loaders is provided, which can cool the hydraulic oil timely, guarantee the normal work of the machine and improve the work efficiency of the loader. The utility model is characterized in that it consists of the heat radiators connected with the hydraulic oil circuit in serial mode and the pressure cooling system consisting of the fans opposite to the heat radiators, with the fans consisting of the fan blades driven by the electric motor. The advantages are with small volume, good heat dissipation effects, convenient installation and low power consumption, so it can be widely applied in the hydraulic system of small engineering machines for temperature reduction and cooling.
Description
Technical field
The utility model discloses a kind of small sized loader hydraulic oil cooling device below a ton that is applicable to, belong to the engineering mechanical device technical field.
Background technique
Before the utility model is made; small sized loader below one ton is in long time continuous working (more than two hours); especially during the broiling summer; hydraulic fluid temperature raises, and the moved arm lifting or the rotating bucket strength deficiency of equipment occur through regular meeting, and is slow in one's movements; the hydraulic system that situation is serious can not be worked; must stop carry out hydraulic oil cooling after, just can work on, influence the performance and the working efficiency of this machine.
Summary of the invention
At the deficiency of prior art, the technical problems to be solved in the utility model provides a kind of hydraulic oil that makes and in time obtains cooling, guarantees this machine proper functioning, the hydraulic oil cooling device of the small sized loader of the working efficiency of raising loader.
Technical characteristics of the present utility model is in the loop of the hydraulic oil of small sized loader, increases to force cooling heat radiator, so that hydraulic oil is cooled in the course of the work, guarantees the loader proper functioning.
Below introduce structure of the present utility model in detail: a kind of small sized loader hydraulic oil cooling device, it is characterized in that being made of the pressure cooling system that is serially connected in the radiator in the hydraulic oil circuit and form over against the fan of radiator, fan is made up of the flabellum of driven by motor.
During the utility model work, the small sized loader oil pump by multiple directional control valve, is transported to operating cylinder with hydraulic oil, when oil cylinder is finished the work, hydraulic oil turns back in the fuel tank by this cooling unit, can make hydraulic oil obtain cooling thus, guarantees the loader hydraulic system proper functioning.Motor rotates by generator drive driven by motor fan.Perhaps the vee belt connects motor and fan formation power train, is cooled off fully in the time of can making hydraulic oil by radiator, keeps the normal working temperature of hydraulic oil, makes and loads the function continuous operation.
The utility model has the advantages that volume is little, good heat dissipation effect, easy for installation, power consumption is few, can be widely used in the hydraulic system cooling cooling of small engineering machinery.
Description of drawings
Figure of description is use of the present utility model and structural representation.Among the figure: 1-radiator, 2-fan, 3-motor, 4-generator, 5-vee belt.
