Magnetic-Assisted Electric Contact Pressure Gauge YXC100, Special
Pressure Gauge For Filter Press
1. In order to ensure that the elastic element of the pressure
gauge can work reliably within the safe range of elastic
deformation, the selection of the pressure gauge range should not
only be based on the size of the measured pressure, but also
consider the speed of the measured pressure change. enough room.
When using a pressure gauge to measure stable pressure, the maximum
working pressure should not exceed 2/3 of the range;
2. Use a pressure gauge to measure the pulsating pressure, and the
maximum working pressure should not exceed 1/2 of the range;
3. When using a pressure gauge to measure high pressure, the
maximum working pressure should not exceed 3/5 of the range. In
order to ensure the measurement accuracy, the minimum working
pressure should not be lower than 1/3 of the range. According to
this principle, after calculating a value according to the measured
maximum pressure, select a measurement range slightly larger than
this value from the product catalog of the pressure gauge.
4. It should be selected according to the working pressure of the
boiler. The limit value of the range scale should be 1.5 to 3.0
times the working pressure, preferably 2 times. In industrial
boilers, the actual situation is that the actual operating pressure
of the boiler is always lower than the rated pressure on the
nameplate, both industrial steam boilers and hot water heating
boilers. For example, for a 4t/h steam boiler, the rated pressure
is 1MPa. If the manufacturer is equipped with a pressure gauge
according to 1.5 times, it should be equipped with a 1.6MPa range
pressure gauge. If the user is required by the production process,
the actual operation can meet the process requirements under the
pressure of 0.5MPa. At this time, when the range is run, the
pointer of the pressure gauge points to a position less than
one-third of the range, and the angle that the pointer rotates is
very high. Small. That is, the range of the pressure gauge selected
is too large.
The same is true for hot water boilers. For example, the rated
pressure of the heating boiler is 0.7MPa, and the pressure gauge
should be 1MPa or 1.6MPa. If the pressure gauge is equipped with
1MPa, it is afraid that the pressure gauge will be overloaded
during the hydraulic test, so it is equipped with a range of 1MPa
or 1.6MPa. 1.6MPa pressure gauge. In actual operation, as long as
0.2MPa can meet the heating requirements, and the pointer of the
pressure gauge points to one-eighth of the range, it is difficult
to make people believe in the accuracy and sensitivity of the
pressure gauge.
5. In order to solve the above problems, two kinds of pressure
gauges should be used, that is, in the hydraulic test, the pressure
gauge equipped by the boiler factory according to the rated
pressure should be used;
6. Equipped with a pressure gauge according to 2 times the actual
working pressure during daily operation. If the working pressure is
0.2MPa, a pressure gauge with a range of 0.4MPa should be used. In
this way, the pointer is in the middle of the dial, vertically
upward. The seat pressure of the safety valve is also adjusted
according to the working pressure, and the pressure gauge still has
enough margin to cope with the overpressure indication.
