Technical field
The utility model relates to a kind of rotary drilling rig, relates in particular to a kind of rotary drilling rig hydraulic oil temperature cooling unit.
Background technique
Rotary drilling rig is a kind of large-scale engineering machinery equipment, and its action drives by oil hydraulic motor and hydraulic jack, and hydraulic system is due to throttling and spill losses in addition, and oil temperature rises very fast, needs radiator cooler.Some rotary drilling rigs in order to reduce oil temperature, have all been installed the oil temperature cooling unit at present, and the working principle of these devices is that after rotary drilling rig started, cooling fan was with regard to full-speed operation.But two shortcomings are arranged like this: the one, the temperature-controlled fan full-speed operation, energy loss will increase, and the 2nd, the electric fan of long-term full-speed operation easily produces fatigue, has reduced the working life of oil temperature cooling unit.
The model utility content
Technical problem to be solved in the utility model is: a kind of rotary drilling rig hydraulic oil temperature cooling unit is provided, can automatically regulate cooling fan rotation speed according to the height of hydraulic fluid temperature, rotating speed that also can manual tune hydraulic pressure cooling fan extends its working life.

A kind of rotary drilling rig hydraulic oil temperature cooling unit, comprise hydraulic oil container 1, gear pump 2, proportional electromagnetic valve 3, temperature control motor 4, oil cooler 5, working oil path 6, temperature transducer 7, programmable controller 8 and display device 9, gear pump 2, proportional electromagnetic valve 3 are connected with hydraulic oil container 1 by temperature control motor 4, and working oil path 6 is connected with hydraulic oil container 1 by oil cooler 5, and proportional electromagnetic valve 3 is connected with display device 9 by programmable controller 8 with temperature transducer 7.
Between described oil cooler 5 and hydraulic oil container 1, return filter 10 is set, is used for filtering the impurity in oil circuit.
Described programmable controller 8 is the PLC programmable controller.
Automatic speed regulation interface 11 and manual governing interface 12 are set on described display device 9, and this interface can carry out automatic speed regulation and manual governing is switched.
Described display device 9 is liquid crystal display.
Working principle of the present utility model: gear pump is followed engine running work, is the wound oil cooling circuit fuel feeding, and gear pump is from the hydraulic oil container oil suction, connects respectively the temperature control motor loop and by the bleed-off circuit of proportional solenoid valve control.Programmable controller receives the voltage signal of temperature transducer, programmable controller calculates hydraulic fluid temperature, just export variable current signal according to Temperature numerical and drive proportional electromagnetic valve, namely export larger electric current when temperature is high, output small electric stream when temperature is low, when temperature during lower than 50 ° of C, no current output.The open amount of proportional electromagnetic valve reduces with the increase of the output current of control programmable controller.Namely when oil temperature was low, small electric stream was exported in programmable controller output, and the proportional electromagnetic valve open amount is large, the most of passing ratio solenoid valve of cold oil this moment by-pass throttle, and fraction oil driving temperature control motor carries out cooling to oil cooler, and at this moment fan speed temperature is slower; When oil temperature is high, the larger electric current of programmable controller output output, the proportional electromagnetic valve open amount reduces, this moment cold oil fraction passing ratio solenoid valve by-pass throttle, most of oil drives the temperature control motor and oil cooler is carried out cooling, at this moment fan speed temperature is very fast.When there is no output current, the proportional electromagnetic valve standard-sized sheet, the whole flows of gear pump are through the solenoid valve off-load.
The beneficial effects of the utility model are: temperature control motor full-speed operation rate reduces, thus the working life of having improved the temperature control motor; Avoid simultaneously under the low-temperature condition temperature control motor to run up and also played the effect of environmental protection and energy saving, when the temperature-controlled fan automatic speed regulating function lost efficacy, also can control by the display device manual tune rotating speed of temperature control motor.
