The door lock assembly on a front-load washer mechanism locks the washer door to prevent the door from opening during the wash cycle or the high-speed spin cycle. The door lock assembly includes the door latch which grabs the door strike and switches that signals to the control system whether the washer door is closed or open, locked or unlocked.

agitation, which r equires relatively high energy consumption per unit of volume (Doran, 1995). Th ere is a great variety of impellers that are described, which produce different flow
Effect of agitation speed on generation of submicron size bubbles in 1 mM KCl solution of pH = 6.0. The agitation time was fixed at 30 min (measured with DLS) [ 39 ]. It is worth noting that agitation is one of the key steps in flotation, since it has been proved that high-intensity conditioning (HIC) improves the flotation performance.

After calculating the various scores or values for your three main components, you can multiply all three values to determine your OEE. In this case, if the quality is 97.5% or 0.975, performance is 95.8% or 0.958, and your availability score is 91.7% or 0.917, your OEE measurement should be 85.7% or 0.857.
