Application of damper |
Applications
Cavitation, liquid hammer and pressure peak may occur in air or fluid systems with varying flow rates, such as the rapid closing of the valve or the start and stop of the pump.
Even at relatively low operating pressures, these problems may occur at the entrance and exit.
Medium condition
In the liquid containing particles, nozzle clogging may occur. The vertical mounting of pressure transmitter minimizes the risk of clogging because the flow of fluid is limited to the initial start-up while the volume behind the nozzle is fixed and the nozzle aperture is relatively large (1.2mm).
