In boilers, fluid systems (gases or liquids) and
machinery, pressure gauges and
valves are key to control and monitoring. Pressure gauges analyze the force
applied by a liquid or gas to a surface, indicating whether the system is
operating properly or adjustments should be made to increase or decrease
pressure and maintain safety at all times.
Although they do not require much maintenance, it
is necessary that they receive a periodic calibration, review and monitoring to
avoid that the pressure causes them to fail due to the natural wear and tear
generated by the gases and liquids, which will cause downtime or malfunctions
that are dangerous. Below we will give you some tips to avoid possible failures
and keep them in optimal condition.
1. REDUCE
VIBRATIONS
All machinery vibrates at different levels and most
gauges are designed to withstand a certain amount; however, excessive
mechanical vibration can damage the meter mechanism. Reducing machinery
vibrations is the best way to avoid damage and failure; you can also opt for
liquid-filled meters or direct drive meters, which have a single moving part,
which makes them ideal for resisting vibrations.
2. PULSATION
AND OVERPRESSURE
Overpressure peaks often occur when pulsation
occurs within pressure systems; when they are sporadic they do not usually have
an effect on the measuring devices, although when they are constant the
internal parts can break and fail. For this reason, it is important to regulate
fluctuations with the use of a pressure damper, which will help prevent
pulsation by absorbing pressure shocks.
3. EXTREME
TEMPERATURES
The pressure gauges have an operating range in
terms of temperatures, when it is exceeded, its internal components can be
damaged, mainly the metallic ones that expand and those of polymers that melt.
For less control of the temperature in the pressure gauge in Shanghai,
it is recommended to have cooling elements, such as air flow or temperature
adjustments with fluid.
4. BEWARE OF
CORROSIVE MATERIALS
If corrosive materials are handled in their
machinery, piping systems, boilers, tanks, among other systems where pressure
gauges are used, it is necessary that they purchase meters that have materials
that resist corrosion and thus avoid obstruction, damage and failure.
