Introduction A 12V DC water pump is powered by a 12V 20Ah battery. Considering various efficiencies, how much water can be pumped to a 20-foot-high field at a time? Depending on the conditions you give, the energy that the battery can provide

A 12V DC water pump is powered by a 12V 20Ah battery. Considering various efficiencies, how much wat

According to the conditions you gave, the energy that the battery can provide is obtained by w=pt=UIt=UQ

w=12v×20Ah=12v×20A×3600s=864000j< /p>

Lift water of mass m to a height of 20 feet and overcome gravity to do the work. This can be obtained from w=mgh

m=w/(gh)=864000j÷10m/s? ÷6m=14,400 kg

p>

In theory, 14,400 kilograms (14.4 tonnes or 14.4 cubic meters) of pure water can be pumped simultaneously to a 6 meter field from above. Taking into account the heat loss of the internal resistance of the battery, the motor efficiency of 60-80%, the water pump efficiency of 65% and the water density (l The water is impure and contains impurities but > 1), the actual volume of water pumped. should be between 5.6 tonnes and 8 tonnes.

When we talk about the normal voltage range of a 12 V generator, we peIt is generally assumed that its voltage must be between 13.4 and 16 V. This autonomy is measured with the generator operating normally and the battery connected. If there is no battery connected and the generator load is reduced, the voltage may increase slightly to 14.3 V at idle. However, in this case the data is inaccurate and the system needs to be initialized, so this is usually not discussed. .

When the generator is running and the battery is connected, the measured battery voltage is usually above 13.4 V. If the battery voltage is below 13.4 V, it There may be a problem with the battery, causing difficulty starting. In addition, the charging current at the battery end voltage is generally higher than 15.5 V. Especially when charging with high current, the voltmeter reading can even reach 16 V.

When using the generator, there are someSome points to note: After starting, the oil pressure, water temperature, voltage and other parameters should be checked to ensure stable operation of the unit. After starting, the idle time should not be too long to avoid damage to generator components. Also check oil lines, water lines and electrical appliances for leaks to ensure connections are tight and free of play and vibration. During operation, attention should be paid to protection and monitoring devices to ensure that various parameters are within the normal range and avoid overload. The above is the normal voltage range of 12V generator and some precautions when using it.
