Description
Technical field
The invention belongs to testing laboratory's engine operating state monitoring technical field, be specifically related to not reduction of speed machine oil sample sampler of a kind of engine.
Background technology
Engine is that a kind of friction pair is many, lubricating status is complicated, working environment difference large, parts use the numerous and diverse machine of kind, and it is carried out to monitoring running state, prevents the generation of significant trouble and accident, cost-saved, shortens the design R&D cycle.Oil analysis is as the main method for monitoring operation states of engine, and the key of its accuracy is promptness and the accuracy of oil sample sampling.Sampling method now is mainly divided into 3 kinds: sample valve method, fuel outlet valve method, needle tubing sampling method.Sample valve method refers at certain position of test diesel engine loads onto sample valve, and this method samples easily, cleans, is not subject to the impact of working environment, can carry out simple failure prediction.But the shortcoming of this method is to realize not reduction of speed sampling of engine, and sampling standard is poor, is difficult to carry out synchronous assay; Fuel outlet valve method refers to and adopts diesel engine oil pan bottom fuel outlet valve to sample.The advantage of this method is need to be on diesel engine not another made component, as long as there is the diesel engine of fuel outlet valve all can use.But the oil sample of getting is subject to the impact of environmental baseline larger, and oil sample can not represent the concentration of each element in true operation process, has delay phenomenon, and accuracy is poor, and still cannot realize not reduction of speed sampling; Needle tubing sampling method (also claiming vacuum sampler sampling method) is to adopt disposable syringe to extract oil sample, and the oil in return line is delivered to safety place by flexible pipe, carries out field working conditions synchronized sampling.This method low cost of manufacture, replacing, easy to carry, simple to operate are the methods of the on-the-spot synchronized sampling nowadays comparatively commonly used.Shortcoming is in engine operation process, can have the oil sample of undesired operating point in elongated flexible pipe, need manually be drawn into oil drum, then extract by rule of thumb the oil sample of actual condition point, workload is larger, and different people is also different sample time, and oil sample accuracy is poor.
Summary of the invention
Technical matters to be solved by this invention is inaccurate and inconvenient for the sampling of engine operation process fluid, and not reduction of speed machine oil sample sampler of a kind of engine is provided.
The present invention solves the problems of the technologies described above the technical scheme of employing: a kind of engine is reduction of speed machine oil sample sampler not, comprises micropump 1, oil-feed oil guide pipe 2, fuel-displaced oil guide pipe 3, temperature sensor 4, three-way solenoid valve 5, sampling jar 6, controller 7 and level monitoring inductor 8.The oil-feed oil guide pipe 2 being connected with described engine oil return pipe is connected with micropump 1, micropump 1 is connected with the entrance of three-way solenoid valve 5, an outlet 9 of three-way solenoid valve 5 is connected by fuel-displaced oil guide pipe 3 with the sump on described engine oil inlet pipe, temperature sensor 4 is arranged on fuel-displaced oil guide pipe 3 the connection outlet place with described sump, two outlets 10 of three-way solenoid valve 5 are communicated with sampling jar 6 through switch valve 11, and sampling jar 6 is outside equipped with level monitoring inductor 8.Wherein micropump 1, temperature sensor 4, three-way solenoid valve 5 and level monitoring inductor 8 are connected with controller 7 respectively.
Further, oil-feed oil guide pipe 2 stretches into certain distance in described engine oil return pipe, becomes miter angle with described engine oil return duct fluid flow direction.
The present invention compared with prior art its beneficial effect is:
(1) the present invention adopts micropump undesired oil sample in pipeline can be delivered in fuel tank, and can provide certain pump oil pressure for sampling spot, is convenient to carry out machine oil sampling between high engine speeds on-stream period;
(2) three-way solenoid valve can cause scavenge pipe place machine oil respectively OPS's sampling spot and engine oil return case, to avoid, because sampling causes the minimizing of engine motor oil amount, affecting engine running;
(3) temperature sensor passes through to judge that whether oil-feed oil guide pipe outlet temperature is close with engine oil return temperature, thus the actual oil sample can clearly know draw oil sample into engine running in the time of sampling time; The sampling end time can judge by level monitoring inductor; Whole sampling process can complete in OPS, has both improved promptness and the accuracy of sampling, has guaranteed again staff's safety;
(4) the present invention has realized not reduction of speed machine oil sample sampling of engine, low cost of manufacture, safe coefficient is high, and can be in time to oil recovery sample carry out assay, realize real time fail monitoring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, not reduction of speed machine oil sample sampler of a kind of engine, comprise micropump 1, oil-feed oil guide pipe 2, fuel-displaced oil guide pipe 3, temperature sensor 4, three-way solenoid valve 5, sampling jar 6, controller 7 and level monitoring inductor 8, the oil-feed oil guide pipe 2 being connected with described engine oil return pipe is connected with micropump 1, micropump 1 is connected with the entrance of three-way solenoid valve 5, an outlet 9 of three-way solenoid valve 5 is connected by fuel-displaced oil guide pipe 3 with the sump on described engine oil inlet pipe, temperature sensor 4 is arranged on fuel-displaced oil guide pipe 3 the connection outlet place with described sump, two outlets 10 of three-way solenoid valve 5 are communicated with sampling jar 6 through switch valve 11, sampling jar 6 is outside equipped with level monitoring inductor 8, wherein micropump 1, temperature sensor 4, three-way solenoid valve 5 is connected with controller 7 respectively with level monitoring inductor 8.Described oil-feed oil guide pipe 2 stretches into certain distance in described engine oil return pipe, becomes miter angle with described engine oil return duct fluid flow direction.
Principle of work: first through oil-feed oil guide pipe 2, oil sample reserved pipeline is delivered to sump, adopt temperature sensor 4 monitoring streams to cross the oil temperature of sump, the oil temperature of C.T. sensor 4 measured temperatures and stand actual measurement, when the two is basic identical, switching three-way solenoid valve 5 valve position make oil sample deliver to sampling jar 6 through fuel-displaced oil guide pipe 3.Adopt level monitoring inductor 8 to monitor the variation of engine oil level in sampling jar 6, while reaching requirement, automatic switching three-way solenoid valve 5 valve position make oil sample flow to sump through fuel-displaced oil guide pipe 3, and the pump control switch on controller 7 is closed, and stop sampling.
The sampling start time judges according to 4 temp. displaying functions of temperature sensor, and the sampling end time judges according to level monitoring inductor 8; If it is approaching that oil temperature starts rising or temperature and engine actual engine oil temperature in the fuel-displaced oil guide pipe 3 in sump place, start to get oil, otherwise do not get oil.If machine oil liquid level, higher than the set liquid level of level monitoring inductor 8, stops getting oil in sampling jar 6, otherwise proceed to get oil.
