Pressure transmitters are commonly used instruments and equipment in modern industrial control, and their normal operation affects the normal operation of industrial production. However, whether it is a domestic transmitter or an imported transmitter, some faults will inevitably occur during use, such as the working environment, improper human operation, or the transmitter itself. Therefore, good daily maintenance can extend the service life of the product. The editor will take you to learn how to regularly maintain the pressure transmitter:
1. Patrol inspection
Check the instrument indication for any abnormalities and see if it fluctuates within the specified range; Some transmitters do not have on-site indications, so you need to go to the control room to check their secondary readings. Whether there is debris around the instrument or whether there is dust on the surface of the instrument, it should be promptly removed and cleaned. There are errors, leaks, corrosion, etc. between the instrument and process interfaces, pressure pipes, and various valves.
2. Regular inspection
(1) For some instruments that do not require daily inspection, regular inspections should be conducted at intervals. Regular zero-point inspection is convenient and does not require too much time as the transmitter has a secondary valve, three-valve group, or five-valve group. Regularly carry out sewage discharge, condensation discharge, and venting.
(2) Regularly purge and inject isolation fluid into the pressure pipes of easily clogged media.
(3) Regularly check that the transmitter components are intact and free from serious rust or damage; Nameplates and markings are clear and accurate; The fasteners should not be loose, the connectors should have good contact, and the terminal wiring should be firm.
(4) Regularly measure the circuit on site, including whether the input and output circuits are intact, whether the circuit is disconnected or short-circuited, and whether the insulation is reliable.
(5) When the transmitter is running, its casing needs to be well grounded. Transmitters used to protect the system should have measures to prevent power outages, short circuits, or output open circuits.
(6) During the winter season, the insulation and heat tracing of the instrument source pipeline should be checked to avoid damage to the source pipeline or the measuring components of the transmitter due to freezing.
During the use of products, there may be major or minor malfunctions. As long as we operate and correctly maintain them, we can extend the service life of the product. Of course, daily maintenance is important, but product selection is even more important. Choosing the right product can avoid many unnecessary troubles.
