What is the purpose of the trap in Figure 2-17 and the watch glass in Figure 2-20?
Short Answer
The trap, as shown in Figure 2-15, prevents the backing of tap water into the suction flask from the aspirator. It also prevents liquid in the suction flask from being sucked up into the vacuum system. Figure 2-18 shows how the watch glass is used to reduce dust contamination.
Step by step solution
Definition of vacuum system
Vacuum systems are made out of vacuum pumps and tanks positioned on a skid or a vehicle. A vacuum pump generates a vacuum in the tank, and the oil flows straight from the skimmer or the source of the oil to the tank through a hose or pipe.
