(a) Component Identification:
- A: Pressure gauge
- B: Hydraulic motor
- C: Relief valve
- D: Directional control valve
- E: Filter
- F: Reservoir
- G: Pump
- H: Strainer
(b) Strainer vs. Filter in Hydraulic Circuits:
While both strainers and filters remove contaminants from hydraulic fluid, they differ in their level of filtration and purpose:
Strainer:
- Function: Removes large particles like dirt, debris, and metal chips to protect pumps and other sensitive components from damage.
- Micron rating: Typically has a larger micron rating (50-200 microns), allowing smaller particles to pass through.
- Cleaning: Usually cleaned periodically by removing and emptying the collected debris.
Filter:
- Function: Removes finer particles and contaminants that could cause wear and tear on components.
- Micron rating: Has a smaller micron rating (10-25 microns) to capture smaller particles than strainers.
- Cleaning: May be replaceable or cleanable, depending on the type.
In essence, a strainer acts as the first line of defense against large debris, while a filter provides finer filtration for optimal system protection.
