Technical Field
The invention belongs to the technical field of battery detection, and particularly relates to an exhaust alkaline washing metering device suitable for a valve control type sealed lead-acid storage battery column type safety valve.
Background
The lead-acid storage battery can generate gas due to the reaction of electrolytic water in the later charging period, although the accumulation of electrolytic gas can be reduced by the cathode absorption action, the gas in the storage battery can be slowly accumulated along with the proceeding of float charging and the existence of overcharge in the later period, and if the gas pressure in the storage battery exceeds the valve opening pressure of the safety valve, the gas accumulated in the storage battery can be discharged through the safety valve, so that the internal pressure of the storage battery is reduced. Acid liquor in the storage battery is brought out in the form of acid mist in the gas discharging process. The escape of acid mist can cause the loss of acid liquor of the storage battery, and the output capacity and the service life of the storage battery are influenced; meanwhile, the acid mist can also corrode other equipment and even damage human health when escaping to the outside. On the other hand, the air discharge amount from the safety valve is an important index for measuring the electrolyte loss, if the air discharge amount is large and the air discharge frequency represents that the operation condition of the storage battery needs to be adjusted urgently, the frequent air discharge can also aggravate the water evaporation of the electrolyte, and the failure risk of the battery is further increased.
