Description
Technical field
The present invention relates to a kind of PEMS test methods of crawler-mounted excavator.
Background technique
As the requirement that emission regulation discharges pollutants for non-rice habitats mechanically moving is increasingly strict, it is desirable that carry out vehicle
PEMS (portable system for testing discharge) test, so that it is determined that the emission level under vehicle actual use operating condition, for further drop
Low vehicle exhaust emission.In terms of for current non-rice habitats field PEMS test method the case where basic blank.
The PEMS test in current non-rice habitats field lacks a kind of test side that can be used as standard in the research starting stage
Method.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
The purpose of the present invention is to provide a kind of PEMS test methods of crawler-mounted excavator, can design a kind of crawler belt
Formula excavator PEMS test method, under conditions of fully demonstrating the Drainage feature under crawler-mounted excavator actual job operating condition,
The repeatability of Enhancement Method, compares convenient for different schemes, and has the advantages that strong operability, easy to use.
To achieve the above object, the present invention provides a kind of PEMS test methods of crawler-mounted excavator, including following step
It is rapid:
Step 1: installing and debugs PEMS test equipment;
Step 2: crawler-mounted excavator starts to carry out earthwork from A point to B point;
Step 3: then the earthwork of crawler-mounted excavator successively reduces gear and carries out the earthwork since highest gear
Until operation carries out earthwork until minimizing gear, the duration of the earthwork of each gear is identical;
Step 4: being repeated several times step 3, and crawler-mounted excavator can be carried out when carrying out earthwork from A point to B point
Fine tune job position;
Step 5: when the general power of the engine output of crawler-mounted excavator reaches test specified value or earthwork
Between have reached test the stipulated time until;And
Step 6: data processing is carried out, PEMS test result is obtained.
In a preferred embodiment, the earthwork of crawler-mounted excavator is in the continuity of each gear a length of 10 points
Clock.
In a preferred embodiment, the test specified value of the engine output general power of crawler-mounted excavator is to start
Machine NRTC recycles 5-7 times of function.
In a preferred embodiment, the test stipulated time of crawler-mounted excavator is 2 hours.
Compared with prior art, the PEMS test method of crawler-mounted excavator of the invention has the advantages that this
PEMS test method, method is easy, strong operability;Test loop operating condition is formulated, the row under the conditions of actual job can be represented
Feature is put, test repeatability is good, the contrast test being convenient under different schemes, needed for reduction crawler-mounted excavator PEMS test
Time;The data regularity of acquisition is strong, reduces data and analyzes workload.
Detailed description of the invention
Fig. 1 is the test schematic diagram of the PEMS test method of crawler-mounted excavator according to an embodiment of the present invention.
Specific embodiment
With reference to the accompanying drawing, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention

Schematic diagram.A kind of PEMS test method of crawler-mounted excavator according to the preferred embodiment of the present invention, including the following steps:
Step 1: it before test, installs first and has debugged PEMS test equipment;
Step 2: crawler-mounted excavator is first begin to carry out earthwork from A point to B point;
Step 3: then the earthwork of crawler-mounted excavator successively reduces gear and carries out the earthwork since highest gear
Until operation carries out earthwork until minimizing gear, the duration of the earthwork of each gear is 10 minutes.
Step 4: being repeated several times step 3, and crawler-mounted excavator can be carried out when carrying out earthwork from A point to B point
Fine tune job position;
Step 5: when the general power of the engine output of crawler-mounted excavator reaches test specified value or earthwork
Between have reached test the stipulated time until;And
Step 6: data processing is carried out according to the requirement of non-rice habitats emission regulation, obtains PEMS test result.
In some embodiments, the test specified value of the engine output general power of crawler-mounted excavator is engine
NRTC recycles 5-7 times of function, and the test stipulated time of crawler-mounted excavator is 2 hours.
Above-mentioned time data are merely exemplary, and the present invention is not limited thereto, in testing can be according to specific requirement
Carry out appropriate adjustment.
In conclusion the PEMS test method of crawler-mounted excavator of the invention has the advantage that
