Description
Technical field:
The utility model relates to Hydraulic Power Transmission System, refers more particularly to a kind of big flow cooling unit.
Background technique:
Hydraulic transmission is to transmit the energy and the kind of drive of controlling with liquid as working medium; Hydraulic transmission has many outstanding advantages; Therefore its application is very extensive, yet hydraulic transmission is comparatively responsive to the temperature variation of fluid; The temperature of fluid generally is controlled at the scope about 60 ℃～80 ℃ in the hydraulic transmission, the highest should be above 85 ℃.In the hydraulic transmission after the oily temperature rise, the lubricant film attenuation of relative motion surface, the hydraulic element expanded by heating has increased mechanical wear, and the pump valve class component increases wearing and tearing, even is stuck; After the oil temperature rise, the viscosity of fluid reduces, and the cohesive force of fluid reduces, and leakage increases; Machine run speed is unstable, is easy to generate and creeps, and the stability of a system is affected; Reduce operating accuracy, influence proper functioning, so hydraulic transmission should not be worked under very high temperature.
Summary of the invention:
The purpose of the utility model provides a kind of big flow cooling unit, and the temperature of fluid in the controlled hydraulic system has good energy-saving effect effectively, can guarantee the machine steady running simultaneously, reduces production costs.
The purpose of the utility model is to realize like this; A kind of big flow cooling unit; Comprise valve plate, dual-axle motor, fuel tank; It is characterized in that: described dual-axle motor two ends are provided with plunger pump, and plunger pump is provided with plunger pump filler opening, plunger pump oil outlet, and the plunger pump filler opening is connected through pipeline with fuel tank; The fuel tank left side is provided with cooling unit, and cooling unit is provided with cooling filler opening, cooling oil outlet; Valve plate is provided with valve plate filler opening A, valve plate filler opening B, valve plate return opening; The plunger pump oil outlet is connected with valve plate filler opening A, valve plate filler opening B respectively, and the valve plate return opening is connected through pipeline with the cooling filler opening, and the cooling oil outlet is connected with fuel tank through pipeline.
The described cooling unit of the utility model adopts air cooling or water cooling.
The utility model can controlled hydraulic system in the temperature of fluid, energy saving guarantees the machine steady running, reduces production costs.
Description of drawings:
For the content that makes the utility model is expressly understood more easily,, the utility model is done further detailed explanation below according to specific embodiment and combine accompanying drawing:
Accompanying drawing is the utility model structural representation.
Among the figure 1, the plunger pump oil outlet, 2, plunger pump, 3, dual-axle motor, 4, the plunger pump filler opening; 5, valve plate filler opening A, 6, valve plate, 7, cooling unit, 8, the cooling filler opening; 9, cooling oil outlet, 10, relief valve, 11, valve plate filler opening B; 12, selector valve, 13, the valve plate return opening, 14, fuel tank.
Embodiment:
Below in conjunction with accompanying drawing the utility model is described further:
With reference to accompanying drawing; A kind of big flow cooling unit comprises valve plate 6, dual-axle motor 3, fuel tank 14, it is characterized in that: described dual-axle motor 3 two ends are provided with plunger pump 2; Plunger pump 2 is provided with plunger pump filler opening 4, plunger pump oil outlet 1, and plunger pump filler opening 4 and fuel tank 14 are connected through pipeline; Fuel tank 14 left sides are provided with cooling unit 7, and cooling unit 7 is provided with cooling filler opening 8, cooling oil outlet 9; Valve plate 6 is provided with valve plate filler opening A5, valve plate filler opening B11, valve plate return opening 13; Plunger pump oil outlet 1 is connected with valve plate filler opening A5, valve plate filler opening B11 respectively, and valve plate return opening 11 is connected through pipeline with cooling filler opening 8, cools off oil outlet 9 and passes through pipeline and be connected with fuel tank 14.As another mode of execution of the utility model, described cooling unit 7 adopts air cooling or water cooling.During practical implementation, hydraulic system has adopted dual-axle motor two ends plunger pump, and the two ends plunger pump feeds valve plate filler opening A, valve plate filler opening B directly from the fuel tank oil suction; This two-way filler opening drives two groups of selector valves respectively, and relief valve carries out work, because two groups of oil circuits carry out work simultaneously; Therefore in the course of the work, the oil temperature constantly raises the hydraulic oil of rising; Get into cooling unit through the valve plate return opening, oil returns fuel tank from the oil outlet of cooling unit after supercooling.
