7.2.7. Accumulators with a magic eye
The magic eye gives the chance receptions of the information on level of electrolit and about level of gymnastics of the checked accumulator (fig. 7.12
Three various colour indications are possible.
It is necessary to consider that if АКБ is more senior 5 years and the colour indicator of "a magic eye is decoloured, it is necessary to replace the accumulator new.
At accumulator additional charge, and also during movement under a magic eye air vials can be formed. They deform indications of the colour indicator of "a magic eye.
Procedure for test
If accumulators are for technical reasons equipped by stoppers these stoppers are stuck by a polymeric film.
Before carrying out of control survey it is necessary slightly and to knock cautiously with the screw-driver handle on a magic eye – thus air vials disappear.
Consider indications of the colour indicator of "a magic eye.
Control survey of the storage battery
Before carrying out of measurements, for example, pressure of a current of rest, density of electrolit or accumulator check under loading, it is necessary to spend control survey of the accumulator.
If the accumulator case is damaged – because of case damage probably вытекание electrolits.
If polar conclusions of the accumulator (conclusions АКБ) are damaged – because of damage of polar conclusions of the accumulator contact of connections of cables is not provided. Thereof there can be an ignition of a cable and occur failure in an electric equipment.
If its original stoppers are twisted in the accumulator – stoppers should be supplied by a sealing ring. At утере or damage it is authorised to use only original stoppers of the same design.
