Description
Technical field
The utility model relates to a kind of engine rig test main oil gallery temperature precise control device, belongs to engine test technical field, particularly engine test-bed engine oil outer circulation domain of control temperature.
Background technology
At present, in the process of exploitation engine, need to carry out various stand function test to development and to standard specimen machine, in bench test process, need external oil circulation, lubricating system state in accurate Control experiment process.
In bench test process, the oil temperature of engine main oil gallery is the key factor affecting engine mechanical loss, and existing bench test engine oil recycle system only possesses simple heating and cooling function.
Summary of the invention
The purpose of this utility model is to provide a kind of engine rig test main oil gallery temperature precise control device, and it can realize long-range fine adjustment, control the main oil gallery oil temperature under different rotating speeds in engine rig test process.
The technical solution of the utility model is achieved in that a kind of engine rig test main oil gallery temperature precise control device, by engine body, oil sump, engine main oil gallery, temperature sensor, variable ratio frequency changer lubricating oil pump, dielectric heater, heat-exchange device, cooling tower, remote temperature regulating system forms, it is characterized in that: temperature sensor is connected on the engine main oil gallery of engine body, remote temperature regulating system receiving end connects temperature sensor, remote temperature regulating system control end connects heat-exchange device, heat-exchange device is connected with dielectric heater and cooling tower, the oil pipe pipeline of oil sump is through heat-exchange device, the oil pipe pipeline of oil sump there is variable ratio frequency changer lubricating oil pump.
Good effect of the present utility model is that its end in machine oil outer circulation adopts the mode quick adjustment of control medium temperature to enter the oil temperature of engine, and according to the temperature of engine main oil gallery temperature sensor feedback, by the mode of remote adjustment, ensure the accurate control of main oil gallery oil temperature under different rotating speeds in engine test process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as shown in Figure 1, a kind of engine rig test main oil gallery temperature precise control device, by engine body 1, oil sump 2, engine main oil gallery 3, temperature sensor 4, variable ratio frequency changer lubricating oil pump 5, dielectric heater 6, heat-exchange device 7, cooling tower 8, remote temperature regulating system 9 forms, it is characterized in that: temperature sensor 4 is connected on the engine main oil gallery 3 of engine body 1, remote temperature regulating system 9 receiving end connects temperature sensor 4, remote temperature regulating system 9 control end connects heat-exchange device 7, heat-exchange device 7 is connected with dielectric heater 6 and cooling tower 8, the oil pipe pipeline of oil sump 2 is through heat-exchange device 7, the oil pipe pipeline of oil sump 2 there is variable ratio frequency changer lubricating oil pump 5.
Engine, in bench test process, is accurately controlled engine main oil gallery temperature by whole heat-exchange system and tele-control system.
When engine carries out bench test, hypothesis test standard regulation engine outer circulation machine oil is 90 ± 1 DEG C.When the engine speed is lower, the heat that engine running itself produces is less, now need, by described remote temperature regulating system 9, the heating-up temperature of whole system is adjusted to more than 90 DEG C, and according to the different adjustment heating-up temperature of engine speed, along with the rising of rotating speed, heating-up temperature moves closer to 90 DEG C.Make main oil gallery temperature stabilization at 90 ± 1 DEG C, and after every speed temperature stabilization acquisition test data.And when engine speed is higher, the heat that engine running itself produces is very large, now need, by described remote temperature regulating system 9, the heating-up temperature of whole system is adjusted to less than 90 DEG C, and along with the rising of engine speed, continue the heating-up temperature of reduction system, the intervention passing through told cooling tower 8 reduces this heat produced in systems in which in time running up of engine.According to rotating speed different adjustment heating-up temperature, when waiting engine to reach rated speed, system heating temperature may far below 90 DEG C.This system also regulates the oil temperature in whole loop at any time by told remote temperature regulating system 9, meet the demand of different tests to main oil gallery oil temperature.
