What is the function of a bypass valve of gear pump in the fuel dispenser?
Bypass valve is a parts of the gear pump in the fuel dispenser. It is mainly used to limit the maximal pressure of hydraulic system
and protect it from damage by the high pressure.It also could adjust flow rate of the fuel dispenser.Bypass valve is important in the
hydraulic system through which oil is pumped to maintain an even pressure and keep the system operating.It is crucial mechanisms
for controlling the flow and pressure of liquids.
The bypass valve is triggered by a springloaded mechanism that opens when fluid pressure becomes too high or too low. As long
as the pressure is the same on both the inlet and the outlet side of the spring, the switch remains closed. But if the pressure builds
up too much on one side, the spring is compressed, causing the switch to open. Without bypass valve, the pump may be still running ,
the oil could create too much pressure with nowhere to flow out, leading to a stalled engineor an explosion. But before that happens,
the bypass valve opens to vent the pressure and divert the oil back to the pump’s reservoir.
