Fault rate of countrywide medium-sized tractor was on average according to investigation in March 2019 10.09% , rise compared to the same period 0.42% , annulus comparing rises 8.53% . Next graphs pursue to was compared with fault rate of medium-sized in Feburary tractor in January.
| Agriculture machinery small classroom | Medium-sized in March tractor
The tractor began to use gradually March, especially and other places of northwest area, Shanxi enters spring ploughing earlier, begin of spring ploughing in succession as each district, the fault rate of medium-sized March tractor rises apparently, annulus rises considerably than Feburary, fault rate of medium-sized March tractor rises to 10.09% . To tractor industry character, spring ploughing should occupy tractor industry annual about 60% of main workload, and spring ploughing is centered in the Lian Yuan area such as northwest, north more, give priority to with four-wheel drive, to each tractor manufacturer character, the pressure of spring ploughing is greater still, want to make service of good spring ploughing, must from personnel, fittings, car, information 4 respects do good arrangement to attemper, with " fast " the word does good market servive routine for the center, may appear to wait for a problem because of serving to cause an user not in time to complain otherwise. Next graphs were Feburary 2019 countrywide medium-sized tractor histogram of each system fault rate:
Medium-sized this month tractor in each system breakdown, engine and auxiliary unit breakdown are occupied than 22.6% , fault rate is ranked the first; Electric equipment breakdown is occupied than 18.3% , fault rate is ranked the 2nd; Breakdown of system of hydraulic pressure promotion is occupied than 14.9% , fault rate is ranked the 3rd; Rear system breakdown is occupied than 13.0% , fault rate is ranked the 4th. Procrastinate in this month with procrastinate to be compared greatly, each system breakdown takes the engine in comparing and auxiliary unit, it is the first, pull hydraulic pressure to promote systematic breakdown to occupy greatly comparing a rank is the 2nd, pull rank of breakdown of electric equipment system to occupy greatly comparing is the 3rd, ranking the breakdown system of the 4th is rear. Next graphs were March 2019 each system breakdown occupies medium-sized tractor than the graph:
The typical breakdown that appears on tractor of the horsepower in March 2019 has:
Part of output of power of rear of a 804 tractors has Shanxi abnormal knocking
An agency of area of the Shanxi in market survey is mirrorred, a 804 tractors have abnormal knocking, particular case is: After the tractor is started, make an appointment with rear motivation to output the position to have abnormal knocking reputation, if operate the deputy separation and reunion of the tractor,handle is pulled, criterion abnormal knocking disappears, if will deputy separation and reunion operates,handle is put down, no matter dynamical output is hanged in neutral position, or 760 turn / cent or 820 turn / cent position, have abnormal knocking reputation, but abnormal knocking sound also is not too big, output of the power in using also had not appeared breakdown.
Output of power of this 804 tractors is in abnormal knocking, have very much actually representative, this kinds of abnormal knocking not only be have on 804 tractors, the author sees, the spot has listened, such as 904, 804, 704, 604, 504, 404, even 1004, 1204 tractors have similar abnormal knocking reputation, the sound that knock is touched each other between similar gear, somes some car voice are big, have a little bit voice yield a car is small. Affirm above all, this kind of sound belongs to abnormal knocking for certain, abnormal, if voice is too big, suggest to manufacturer the newspaper is repaired, requirement maintenance; But if voice is not big, proposal user is repaired to manufacturer newspaper put on record, in be being operated actually but of short duration is not handled.
We come to an analysis below, why when tractor motivation is defeated by provenance to have slight abnormal knocking, can is of short duration handled?
In real service, we had encountered output of power of a lot of new tractors to be in those who have abnormal knocking, our analysis identifies this abnormal knocking if gear tooth form has clearance of inadequacy of precision of deviation, gear, gear to be caused greatly,give priority to, concern with the structure of tractor itself additionally, that is to say, some abnormal knocking are " the embryo takes " , " congenital " , the service personnel that in the car that batch abnormal knocking exists in the factory you think one to allow tractor plant is handled to you, he does not have this level. Because existence abnormal knocking changes motivation to output complete set gear to the user,I ever had seen, there still is abnormal knocking after the result was changed, and compare return so big, changed to the user again finally, the user is dead also heart, say were not repaired, because this abnormal knocking makes a quality standard and structural decision, bad to repair, also with repair a level to have nothing to do.
General manufacturer is grooming oneself metropolis when serving personnel is told, plant to this do not affect use abnormal knocking, the requirement serves personnel to be not repaired to the user, also repair because of you bad, standard practice is to give an user a consent, tell an user clearly, won't affect use, although be at ease,use, if guide because of this abnormal knocking,damage, manufacturer gives you 3 packets. Serve as an user to also need not be afraid of actually, you are repaired to manufacturer newspaper after putting on record, he is not repaired to you, let you be at ease with, you are used is, if give an issue, the manufacturer that seeks consent can, but if you do not sign up for,repair put on record, the car became bad when looking for manufacturer, he may be met carry you manage. Nevertheless, according to small the experience that makes up more than 20 years looks, dynamical output is in new car to have this kind of slight abnormal knocking, what cause use damage because of this kind of abnormal knocking is true still not much, of course, we or hope tractor do not have abnormal knocking, should not appear to let an user sit to the thing of the Lai Weiquan on tractor bonnet like run quickly more.
Above is all today share, the hope can bring a help for everybody, welcome young associate people leave a message evaluate and to table a proposal oh ~
