Pressure gauges play multiple important roles in the operation of hydraulic systems.

Ensure the normal operation of the system: When the hydraulic system is in operation, it needs to work within a specific pressure range to ensure its stable performance. The pressure gauge can display the system pressure in real time. The operator can compare it with the set value to ensure that the system pressure is within the normal range. In the hydraulic system of a crane, the pressure is monitored through a pressure gauge to ensure that the system can provide stable power for the lifting of the boom and the hoisting of goods, guaranteeing the normal operation of the crane.

Achieving precise control: Many hydraulic systems require precise pressure control for their tasks. For instance, in hydraulic forming equipment, different workpieces require different pressure values for forming. Operators precisely adjust the pressure based on the readings of the pressure gauge to ensure that the equipment outputs an appropriate pressure, thereby guaranteeing the forming accuracy and quality of the workpieces.

Ensuring system security: When the system malfunctions and causes excessive pressure, it may lead to safety accidents such as pipe rupture, component damage, and even explosion. The pressure gauge can promptly display abnormal pressure, alerting the operator to take emergency measures such as activating the pressure relief device or stopping the system operation, to prevent accidents and protect the safety of equipment and personnel.
