Abstract
The invention discloses a hydraulic cooling loop system which comprises an oil tank (1), wherein a hydraulic cooling loop is connected to the oil tank (1) and is connected with an oil cylinder; the oil tank (1) is connected with the hydraulic cooling loop through an input header pipe (2) and a reflowing header pipe (3); and the hydraulic cooling loop comprises two hydraulic cooling branches. According to the hydraulic cooling loop system provided by the invention, the input pipeline is separated from the reflowing pipeline, therefore, the highly-frequent friction of the hydraulic oil to the same pipeline can be reduced, and the heat can be fundamentally reduced; and a radiating device is additionally arranged, so that the temperature of the hydraulic oil is further reduced, thus, the whole equipment can run for a long time, and as a result, the service efficiency is greatly improved, and the input cost is saved.
Description
Technical field
The present invention relates to a kind of oil hydraulic circuit, relate to specifically a kind of fluid pressure drop temperature loops system.
Background technique
At present, oil hydraulic circuit in the sanitation engineer all is by same pipeline when hydraulic oil exports oil cylinder to and is back to fuel tank from oil cylinder from fuel tank, and the hydraulic oil of high pressure can rub with tube wall through same pipeline repeatedly, and produce a large amount of heats, wherein the latus rectum of valve seat and spool is usually little than stimulating the menstrual flow of hydraulic pipe line, formation tightens phenomenon, the generation heat is very big, and when heat is too high for the use safety of equipment, must stop using equipment, limit to greatly the use of equipment, caused a large amount of wastings of resources.And the cooling system of prior art all is outside cooling, only be that attached cooling system (such as radiator, radiation fan etc.) externally is set, and the cooling rate of outside cooling system is slower, cooling demand in the time of can't satisfying actual use far away, the speed that can only delay to heat up can not fundamentally solve the problem of intensification.The complex structure of outside cooling system, maintenance and repair inconvenience, the effect utilization ratio is low, also can greatly increase simultaneously the energy consumption of integral device, can not satisfy the demand to equipment.
Summary of the invention
In view of this, the invention provides a kind of fluid pressure drop temperature loops system, with input and backflow the pipeline of process separate, thereby reduced hydraulic oil same pipeline high frequency is rubbed, from basic few generation that has reduced heat, and be aided with sink, further reduced the temperature of hydraulic oil, from so that integral device can be moved for a long time, greatly improved the efficient of using, saved input cost.
For solving above technical problem, technological scheme of the present invention is:
Fluid pressure drop temperature loops system comprises fuel tank, it is characterized in that, is connected with the fluid pressure drop temperature loops on the described fuel tank, and this fluid pressure drop temperature loops also links to each other with oil cylinder.
Further, above-mentioned fuel tank links to each other with the fluid pressure drop temperature loops with return header by the input house steward.
As preferably, described fluid pressure drop temperature loops comprises two hydraulic pressure cooling branch roads.
As preferably, described hydraulic pressure cooling branch road comprises intake line and return line.
Further, above-mentioned intake line links to each other with input house steward and return header respectively with return line.
Further, described oil cylinder comprises large consumption oil cylinder and little consumption oil cylinder, and large consumption oil cylinder links to each other with a hydraulic pressure cooling branch road respectively with little consumption oil cylinder.
As preferably, be provided with two solenoid valves and a relief valve on the described hydraulic pressure cooling branch road.
Preferred as another kind, also be provided with one-way valve on the described step-down cooling branch road.
In addition, also be provided with power source and pressure transducer on the described input house steward.
Simultaneously, also be provided with radiator on the described return header.
Compared with prior art, the present invention has following beneficial effect:
The present invention is provided with intake line and two pipelines of return line, so that being divided into two different pipelines when inputting from backflow, hydraulic oil advances, avoided the hydraulic oil same pipeline that rubs back and forth, thereby reduced greatly the heat that hydraulic oil produces in running, separate simultaneously the surface of contact that pipeline has also strengthened pipeline and air, and then improved the effect of pipeline self to external world's heat radiation, further controlled the lifting of temperature;
The present invention also is provided with radiator on return header, when hydraulic oil refluxes to fuel tank, can further reduce the temperature of hydraulic oil, can better control the rising of oil temperature;
The present invention is provided with one-way valve at return line, large flow oil cylinder hydraulic oil return is arrived fuel tank by the direct oil return of the one-way valve on the return line, reduce the heat that hydraulic oil produces by multichannel valve seat and spool, and one-way valve also reaches the purpose that control hydraulic oil flows to, avoid hydraulic oil generation adverse current, thereby guaranteed the normal operation of hydraulic system.
Description of drawings
Fig. 1 is system schematic of the present invention.
Embodiment
Core thinking of the present invention is, a kind of fluid pressure drop temperature loops system is provided, with input and backflow the pipeline of process separate, thereby reduced hydraulic oil same pipeline high frequency is rubbed, from basic few generation that has reduced heat, and be aided with sink, further reduced the temperature of hydraulic oil, from so that integral device can be moved for a long time, greatly improved the efficient of using, saved input cost.
In order to make those skilled in the art understand better technological scheme of the present invention, the present invention is described in further detail below in conjunction with the drawings and specific embodiments.
