After a period of use and pressure, some deformation and wear will inevitably occur in the mandrel of the pressure gauge, and various errors and faults will occur in the pressure gauge. In order to ensure its original accuracy without distortion of value transmission, it should be replaced in time to ensure that the instructions are correct, safe and reliable.
Pressure gauges should be cleaned regularly. Because the pressure gauge interior is not clean, it will increase the wear and tear of various parts, thus affecting its normal work, serious pressure gauge failure, scrap.
The medium in the pressure measuring part fluctuates greatly, is frequently used, requires higher accuracy, and requires stricter safety factors. The verification period can be appropriately shortened according to specific conditions.
Pressure gauges installed in equipment or pipelines with toxic, flammable and explosive media should be regularly checked for air tightness in order to prevent harmful media from leaking and causing potential safety hazards.
Regular rust removal and anti-rust paint are applied to the metal casing of the pressure gauge to protect the internal parts from damage.
The glass of the dial of the pressure gauge should be well treated for anticorrosion, dust prevention and oil pollution prevention so as to facilitate staff observation. The location of the label should not interfere with reading, and the content on the label should be clear and legible.
The condensate pipes of steam pipes should be well protected against freezing, and the condensate water should be blown out after shutdown in winter to prevent the damage of pressure gauges.
The scrapped pressure gauges should be submitted to the warehouse for disposal in time. No excess pressure gauges should be placed in disorder on the production and operation site.
