Description
Technical field
The present invention relates to the domain of control temperature of coke vehicle hydraulic oil, and in particular to a kind of coke vehicle hydraulic oil temperature intelligence
It can temperature control system.
Background technique
In coke making process, coke vehicle is important equipment, is mechanically moving, and hydraulic system is coke vehicle
Main logic unit, but since condition limits, it is domestic at present generally to use natural wind circulation cooling form without sufficient water source on vehicle
Cooling hydraulic system, it is ineffective.Due to the Effect of Hyperthermic Environment of surrounding, instead summer causes hydraulic at system heating device
System oil temperature is high, seriously affects production run, while oil temperature harm is even more serious on hydraulic system influence.Coking production
When, ambient temperature is high, and machine side is close to long-term 80 DEG C of furnace body side cylinder surface temperature or more, coke pushing during pushing coke operation
200 DEG C or so of vehicle furnace body side, often there are 70 DEG C of high temperature alarms in oil temperature in hydraulic system, causes High Temperature in Hydraulic System to be shut down, to life
It produces and hydraulic device causes hidden trouble.Therefore, the prior art is upgraded, a kind of coke vehicle hydraulic oil temperature intelligence is set
Temperature control system is just particularly important.
State Intellectual Property Office discloses the patent document of Publication No. CN 207178364U, a kind of hydraulic fluid temperature control

Controller and electron assistant oil pump controller, control electron assistant oil pump and electron assistant water pump adjusts automatic transmission oil stream amount
And cooling water flow, realize the function of automatic transmission fluid temperature control.
By retrieval it can be found that there are problems in above-mentioned open source literature is as follows:
CN 207178364U is not configured to that the return gas channel of gas is recycled, and mainly uses PID controller
It realizes the integral element that dynamic controls, in PID control, to the significant effect for inhibiting constant value disturbance, but when undisturbed, integrates ring
For section so that the dynamic characteristic of system is deteriorated, this is certain deficiencies when realizing system control using PID controller；
Hydraulic oil liquid level is measured dependent on liquid level sensor in CN 206190643U.When hydraulic oil liquid level is lower than safe liquid
When position, stop falling the work of the set heater of its invention thoroughly to prevent unexpected situation, this kind of mode is only applicable to the invention
Temperature control of the stretching machine being applicable in stretching process, and in the coking process that the present invention will apply to, Che Shangwu fills
Sufficient water source and long-term 80 DEG C of ambient temperature or more, 200 DEG C or so of pusher machine furnace body side during pushing coke operation, it is seen that
The mode of the measurement hydraulic oil liquid level of CN206190643U is difficult to stabilize to the realization of coke making process vehicle offer feedback signal normally
Work；
Automatic transmission fluid temperature control method in CN 109058441A, be to rely on automatic transmission oil temperature and flow,
Cooling water temperature and flow information combine the oil cooler heat exchange amount spectrum and automatic transmission being stored in control unit of engine
The oil temperature section of efficient operation obtains that the oil stream amount controlled and cooling water flow is needed to be precisely controlled purpose to reach, than
For playing the present invention, invention needs reach temperature control by measuring flow information, cool down purpose, and the dress of measuring flow information
Set and be difficult to steady operation in coke vehicle operation process, thus the invention can not solve it is to be solved by this invention in coke oven
Charging car, pusher machine, the purpose that hydraulic oil temperature temperature control system is run on coke guiding locomotive.
