Storage battery is agricultural machinery it is easy to in using, be compared the component of occurrence breakdown, agriculture machinery is used in start via what problem of regular meeting occurrence storage battery causes faint, cannot start wait for breakdown. Storage battery to the agriculture machinery such as tractor, mower, the proportion that although be on cost,holds is not high, but the effect that it is having to hold the balance however to whole machine. So, understand storage battery whether good still, change ahead of schedule the storage battery that will discard as useless, the service level that can raise agriculture machinery manufacturer and service station of agriculture machinery maintenance effectively to nod and user satisfaction are spent.
Agriculture machinery small classroom | Batteries breakdown
The commonnest judgement in market service whether the method of storage battery breakdown changes namely antitheses, general meeting checks column of storage battery wiring to be in a contact first good, whether is the line that take iron contacted good, if have,shake a contact undesirable phenomenon, new link tightens the test-drive after solid; If wiring contact is good, can change a new storage battery to try, if start normal, explaining is primary vehicle storage battery has a problem. Have visual examination to tearing open the primary vehicle storage battery below next, if crust rouses phenomenon of the ooze outside bag, crackle, electrolyte, decide basically storage battery already damaged; If storage battery exterior is in good condition, without crust crackle, phenomenon of the ooze outside electrolyte, batteries crust did not beat the issue such as the bag, can undertake charging to primary vehicle storage battery, after charging, primary vehicle storage battery can be used normally, explain primary vehicle storage battery is short report only, if charge hind primary vehicle storage battery still cannot be used normally, show primary vehicle storage battery already " abandoned " , need changes new storage battery.
Change comparative trial law serves actually in agriculture machinery in because go easily simply, do not need measure application wider, but this kinds of method is beyond the mark extensive, via regular meeting occurrence miscarriage of justice, cause needless loss to user, manufacturer, ever manufacturer has made count, in the so called bad storage battery that comes in go back, the batteries of 50% is good actually, what these storage battery need is to charge, is not to change, this part good storage battery, it is the error because of judgement only, go there and back meaninglessly between manufacturer and agency, create waste for nothing. How can you just undertake to storage battery farther essence allows to measure decide? Can use avometer law to be measured simply, if can use professional storage battery discharge instrument is better, more accurate.
Use the method that avometer measures simply, it is to let accumulator fill report, carry for nothing measure voltage of storage battery open a way, be more than 12.45V, storage battery is normal; Be less than 12.45V, storage battery short report, need additional electricity. Did not carry out by the requirement may cause cannot start a tractor, even storage battery has a deficit badly report, create storage battery be no longer in force. 2 it is to let storage battery fill report, start moment to measure accumulator next the voltage of two end, storage battery voltage is right now general cannot under 9.6 bend over, if under 9.6 bend over, it is accumulator has a deficit badly report cannot be used.
Measurement technique of professional accumulator discharge instrument, accumulator discharge instrument is to be used at the professional facility that acerbity to lead accumulator has working ability and healthy state detect, ask to receive fine line by the manual above all, observe the condition of accumulator discharge moment, if show voltage is in,above of 9 bend over is good commonly, if under 9 bend over but watch needle is not moved, explain accumulator is in short report state, need charges in time compensatory. If under 9 bend over, and watch needle still continues to drop, proof batteries inside had had short circuit. If be measured,run to 0 bend over, show accumulator inside had been burned.
Compare rigorous measurement technique, it is to measure CCA value, it represents the electric current of cold start-up moment and capacity, those who say is to be in - 18 degrees of or so moment, the storage battery voltage of 12 bend over drops the electric flow that to 7.2 Fu Qianlian add 30 seconds output. For instance the commonly used 120AH storage battery on the tractor, its CCA value is commonly 760, the delegate is in - 18 degrees of or so moment can export 760 electricity continuously 30 seconds, this CCA value has been jumped over greatly more, if CCA value falls fierce, explain storage battery is washed-up already. 50% what if the CCA of storage battery is worth,had set under former plant, must change storage battery.
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 ~
