How to prevent pressure gauge movement deformation? After a period of use and pressure, the pressure gauge movement will inevitably appear some deformation and wear, the pressure gauge will produce a variety of errors and failures. In order to ensure its original accuracy and not make the value of the transmission distortion, should be replaced in time to ensure that the indication is correct, safe and reliable. So, how to prevent the pressure gauge movement deformation? Let's find out.
How to prevent pressure gauge movement deformation? The method to prevent the deformation of the pressure gauge movement:
The pressure gauge should be cleaned regularly. Because the internal pressure gauge is not clean, it will increase the wear of each machine, thus affecting its normal work, serious pressure gauge failure and scrap.
If the medium in the pressure measuring part fluctuates greatly, is used frequently, the accuracy requirement is high, and the safety requirement is strict, the verification period can be shortened appropriately according to the specific situation.
The pressure gauge installed on the equipment or pipeline with toxic, flammable and explosive media should be checked regularly to prevent the leakage of harmful media and cause safety risks.
The metal casing of the pressure gauge is regularly derusting and coated with anti-rust paint to protect the internal parts from damage.
The dial glass of the pressure gauge should be treated with anti-corrosion, dustproof and anti-oil so as to facilitate the observation of the staff. Label position should not interfere with the reading, the content on the label should be clearly discernible.
The condensate pipe of the steam pipeline should take anti-freezing measures, and the condensed water should be blown away after the production is stopped in winter to prevent the damage of the pressure gauge.
Discarded pressure gauges should be sent to the warehouse in time for disposal. Excess pressure gauges should not be piled up in the production and operation site.
