In addition to the performance failure caused by dust attachment in the previous article, and the malfunction or failure caused by pressure fluctuations, bursting discs for dust industry is also facing material selection and installation and maintenance problems in use. These problems will also affect the performance of the rupture disc. If handled improperly, it may also lead to safety hazards and bring potential risks to production.
1. Improper material selection leads to corrosion and damage of bursting discs for dust industry:
In the dust industry, some dust is highly corrosive. If the material of bursting discs for dust industry is not selected properly, it is very prone to corrosion and damage. At the same time, the hardness of the dust will also affect the life of the rupture disc. Hard dust such as quartz sand and emery will scour and wear the surface of the rupture disc under the drive of air flow, especially at the edge of the connection between the rupture disc and the pipeline. Long-term wear and tear will lead to seal failure and leakage problems. Leakage will not only reduce the control accuracy of the system pressure, but may also cause external air to enter the equipment and mix with internal combustible dust to form an explosive mixture, increasing safety risks.
2. Insufficient normative nature of installation and maintenance of bursting discs for dust industry:
The installation quality of bursting discs for dust industry will directly affect the performance, and the common installation problems in the dust industry are mainly reflected in three aspects: the installation direction is wrong, such as the reverse installation of the positive arch type rupture disc, which cannot be raised and cracked normally during overpressure, but is damaged in advance due to the wrong direction of force. Poor sealing, due to the presence of dust particles, the flange connection surface is easily contaminated by dust, resulting in lax sealing between the rupture disc and the flange, and continuous leakage, which not only affects the stability of the system pressure, but also causes dust to overflow from the gap, exacerbating the adhesion problem on the surface of the rupture disc. It does not match the pipeline. In order to reduce costs, some companies choose rupture discs with diameters and pressure levels that do not match the equipment. For example, installing a low-pressure rupture disc on a high-pressure dust pipeline may cause the rupture disc to rupture under normal working pressure, or the pressure cannot be fully released during overpressure. In terms of maintenance, bursting discs for dust industry often creates hidden dangers because of frequent use but little maintenance. Some enterprises have not formulated a regular inspection system, resulting in dust accumulation and corrosion cracks on the surface of the rupture disc that cannot be detected in time. There are also companies that did not replace the new film in order to catch up with the construction period after a blasting of bursting discs for dust industry, but temporarily blocked it, leaving the equipment in a state of no safety protection for a long time.
