Description
Technical field
The utility model relates to Hydraulic Field, more specifically to a kind of automatic cooling controller of hydraulic power unit that can regulate cooling water inflow.
Background technique
During enterprise produces, have many hydraulic stations for the production of transmission and control.General hydraulic station adopts the mode of water quench that the high-temperature liquid force feed of fuel tank is carried out circulating cooling.Concrete operation characteristic, after the oil temperature temperature was increased to setting value, cooling water was started working, and behind the drop in temperature, cooling water quits work.The shortcoming of this mode is, the flow of cooling water is certain, only has water flowing and the two kinds of situations of cutting off the water, and desired temperature is interval large, changes greatlyr, affects the stability of HYDRAULIC CONTROL SYSTEM precision.Do not have at present preferably cooling controller, guarantee that the oil temperature of hydraulic station changes little.
Summary of the invention
The purpose of this utility model is, a kind of pumping plant auto-cool system is provided.Adopt this cooling unit, can guarantee that the hydraulic power unit temperature variation is less, improve the stability of HYDRAULIC CONTROL SYSTEM precision.For achieving the above object, the utility model has adopted following technological scheme:
A kind of pumping plant auto-cool system comprises oil pump, the first temperature transducer, cooler, water pump, three-temperature sensor, the second temperature transducer, fuel tank, automatic control system.Oil pump links to each other with fuel tank through pipeline, and the export pipeline of oil pump is installed cooler, and cooler outlet is taken over the road oil sump tank.Water pump connects rear tube road, water source to cooler.Wherein, described the first temperature transducer is installed in the import of described oil pump, and described the second temperature transducer is installed in the outlet of described cooler.Described three-temperature sensor is installed in the outlet of described water pump.
Described the first temperature transducer, the second temperature transducer, three-temperature sensor connect respectively automatic control system.
Described water pump is by automatic controlling system.
The utlity model has following advantage: can guarantee that the hydraulic power unit temperature variation is less, control hydraulic oil improves the stability of HYDRAULIC CONTROL SYSTEM precision in suitable temperature work.

Embodiment
The below is described in further detail the utility model with the drawings and specific embodiments.
Such as Fig. 1, shown in Figure 2, a kind of pumping plant auto-cool system comprises oil pump 1, the first temperature transducer 2, cooler 3, water pump 4, three-temperature sensor 5, the second temperature transducer 6, fuel tank 7, automatic control system 8.Oil pump 1 links to each other with fuel tank 7 through pipeline, and the export pipeline of oil pump 1 is installed cooler 3, cooler 3 discharge connection road oil sump tanks 7.Water pump 4 connects rear tube road, water source to cooler 3.Wherein, described the first temperature transducer 2 is installed in the import of described oil pump 1, and described the second temperature transducer 6 is installed in the outlet of described cooler 3.Described three-temperature sensor 5 is installed in the outlet of described water pump 4.Described the first temperature transducer 2, the second temperature transducer 6, three-temperature sensor 5 connect respectively automatic control system 8.Described water pump 4 is by automatic control system 8 controls.
In the utility model, start oil pump 1, the hydraulic oil in the fuel tank 7 enters fuel tank 7 through oil pump 1 behind supercooler 3, finish a cool cycles.The first temperature transducer 2 detects the hydraulic oil oil temperature of fuel tank in real time, the second temperature transducer 6 detects cooled hydraulic oil oil temperature in real time, water temperature when three-temperature sensor 5 real-time detection cooling waters are not worked, the data-signal of three temperature transducers is transferred to automatic control system 8.Automatic control system 8 interior set temperature contrast programs, if the oil temperature of the first temperature transducer 2 is far longer than the water temperature that three-temperature sensor 5 detects in real time, then automatic control system 8 is sent the 4 large flows water supply of instruction control water pump, implements cooling.If the water temperature that the oil temperature of the first temperature transducer 2 has just detected in real time greater than three-temperature sensor 5, then automatic control system 8 is sent instruction control water pump 4 small flows and is supplied water the enforcement cooling.The difference size of temperature can be decided according to the situation at scene.The second temperature transducer 6 detects the hydraulic oil oil temperature in real time, also can compare the formation cooling scheme with the water temperatures that the first temperature transducer 2 real-time detection oil temperatures, three-temperature sensor 5 detect in real time.
Cooling unit of the present utility model can guarantee that the hydraulic station temperature variation is less, and control oil hydraulic pump oil improves the stability of HYDRAULIC CONTROL SYSTEM precision in suitable temperature work.One-time investment, simple in structure, easy for installation, can reuse.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described.Although with reference to embodiment the utility model is had been described in detail, will be understood by those skilled in the art that, the technical solution of the utility model is made amendment or is equal to replacement, the spirit and scope that do not break away from technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
