7.2.9. Check of level of electrolyte – joint stock bank with traffic jams

ATTENTION
At the treatment of electrolyte it is necessary to observe surely instructions on prevention of accidents.


Fig. 7.13. The device for check of level of electrolyte in joint stock bank



It is necessary to wear special protective clothes.
You make illumination of internal space of the case of the accumulator only by means of a pocket small lamp.
It is strictly forbidden to highlight internal space of the case of the accumulator by means of an open flame.
Stay with an open flame or with the burning cigarette near accumulators is strictly forbidden.
The correct level of electrolyte of the accumulator is the important factor exerting impact on duration of operability of the accumulator.
In accumulators with clearly mark of a minimum visible outside and a maximum only external visual check of level of electrolyte of the accumulator is required.
Level of electrolyte has to be over a minimum mark, however it is not allowed that it was above a maximum mark.
Turn off traffic jams on accumulators on which external marks of a minimum and a maximum are indistinctly looked through or visibility of level of electrolyte is not provided because of insufficient transparency of the case of the accumulator.
Check electrolyte level, having glanced in the accumulator.
Electrolyte has to be at the level of an internal mark (a cross-piece from plastic). It corresponds to an external tag of the maximum level

Too low level of electrolyte
At too low level of electrolyte because of drying of plates of the accumulator there is a loss of capacity (loss of power) of the accumulator. If plates of the accumulator are not in electrolyte (water solution of sulfuric acid), then there is a corrosion of plates, crossing points of a plate and connectors of sections. This corrosion worsens operability of the accumulator – the accumulator fails.

Fig. 7.14. Capacity for filling of electrolyte in joint stock bank


At too low level of electrolyte to add the distilled water by means of capacity for filling of the VAS 5045 accumulators to a max. mark (fig. 7.14).

NOTE
The design of a jellied branch pipe of capacity for filling of the VAS 5045 accumulator prevents overflow of section of the accumulator and an exit of electrolyte outside. At achievement of max. level of filling supply of the distilled water in accumulator section stops.
Not to allow pollution of electrolyte of the accumulator conducting to the raised self-discharge it is allowed to add only the distilled water.

Twirl traffic jams of sections of the accumulator.

ATTENTION
To provide tightness of various systems of covers of accumulators, in openings of the accumulator the original traffic jams relating to the accumulator have to be screwed up. At loss or damage it is allowed to use only original traffic jams of the same design.

Traffic jams have to be supplied with a sealing ring.

Too high urovenyelektrolita
If the level of electrolyte is too high (the accumulator is crowded), then because of an electrolyte exit (water solution of sulfuric acid) damage is caused to an accumulator environment.
If the level of electrolyte is over an internal mark of level of electrolyte (a cross-piece from plastic) and, respectively, over an external mark of a maximum, then electrolyte should be pumped out without fail.
Turn off traffic jams of sections of the accumulator.
Pump out sulfuric acid a usual pipette until its level is not established at height of a plastic cross-piece or max. mark.
Twirl traffic jams of sections of the accumulator.

ATTENTION
To provide tightness of various systems of covers of accumulators, in openings of the accumulator the original traffic jams relating to the accumulator have to be screwed up. At loss or damage it is allowed to use only original traffic jams of the same design.
Traffic jams have to be supplied with a sealing ring.
