70AH Battery Capacity and Bilateral Tolerance

70AH Battery

Capacity Calculation

• The capacity of a 70AH battery is calculated by measuring the amount of electric charge it can supply over a certain period of time.
• The formula to calculate capacity is: Capacity (Ah) = Total Amount of Charge (Amps) x Time (Hours)
• For a 70AH battery, this means it can supply 70 amps of electric current for 1 hour, or 35 amps for 2 hours, and so on.

What is Bilateral Tolerance?

• Bilateral tolerance refers to the allowed variation in the capacity of a battery from its rated capacity.
• In the case of a 70AH battery, the bilateral tolerance might be ±10%, meaning the actual capacity could be between 63AH and 77AH.
• This tolerance is determined by the manufacturer and is usually specified in the battery's datasheet.
• Bilateral tolerance is important to consider when designing systems that rely on batteries, as it can affect the overall performance and reliability of the system.

Pump Parts

Impellers

• Increase pressure and flow rate of fluid
• Three types: Open, Closed, and Semi-open
• Open impellers: vanes attached to a central hub, not enclosed
• Closed impellers: vanes attached to a central hub, enclosed by a shroud
• Semi-open impellers: combination of open and closed impellers

Seals

• Prevent fluid leakage and maintain pressure
• Three types: Mechanical seals, Lip seals, and O-rings
• Mechanical seals: use rotating and stationary components to create a seal
• Lip seals: use a flexible lip to create a seal
• O-rings: use a circular cross-section ring to create a seal

Shafts

• Connect the driver to the impeller
• Made from stainless steel, carbon steel, or alloy steel
• May be coated with a protective layer to prevent corrosion

Bearings

• Support the shaft and allow smooth rotation
• Three types: Sleeve bearings, Rolling element bearings, and Magnetic bearings
• Sleeve bearings: use a cylindrical sleeve to support the shaft
• Rolling element bearings: use balls or rollers to support the shaft
• Magnetic bearings: use magnetic forces to levitate and support the shaft

Bilateral Tolerance

• Allows for variation in both directions (e.g., ±)
• Example: a shaft with a bilateral tolerance of ±0.1 mm can be 0.1 mm larger or smaller than nominal size
• Important for ensuring proper fit and function of pump parts
