As the title suggests, regarding the pressure gauge installed at the pump outlet, how can we avoid the damage caused by vibrations?
1 A shock-proof pressure gauge can be installed. 2 Add shock absorption as well
It is recommended to install the pressure gauge after the pump has started operating and its vibration has decreased, in order to avoid damage to the gauge caused by shocks. If the vibration is severe after the pump is started, it is recommended not to install a pressure gauge, or to move it to a location where the pipeline vibration is reduced before installation.
1. From a selection perspective: Choose a shock-resistant pressure gauge with an oil-filled dial； 2. From an installation perspective: A U-tube or coiled tube can be installed between the pressure gauge and the root valve; if there are no crystals or deposits in the fluid, a buffer tank can also be placed between the pressure gauge and the device being measured.
In our factory, isolation tanks are installed in front of most pumps, but it’s quite troublesome – during winter, you have to replace the fluid in those tanks with antifreeze. We are a chemical manufacturing company located in the north. . .
Switch to a diaphragm remote transmitter! Since pressure is transmitted to the pressure gauge through a diaphragm and capillary, the gauge can be installed in another location, thereby avoiding any impact on the mechanical vibrations at the pump outlet. If the pressure at the pump outlet is pulsating, it is necessary to use a pressure gauge designed to withstand vibration.
Use an anti-vibration pressure gauge; add support if there is severe vibration.
Install a damping valve, use an anti-vibration pressure gauge
Many people have mentioned shock-resistant pressure gauges. What is the principle behind shock-resistant pressure gauges? What structure enables it to resist earthquakes? Are dampers installed?
1. Install a damper in front of the pressure gauge; 2. Use an oil-filled pressure gauge. Apply both measures simultaneously.
