Gyntaf o holl, gwirio a yw'r solenoid falf solenoid coil methiant% 3f
Yn y DCS i y dau-safle falf i agored neu gau y signal, a yna gweld whether y solenoid falf i colli pŵer, cyffredinol gwrando y sain yn y olygfa If can not clyw, y coil yn yn problem 2c fel ar gyfer y solenoid falf ei hun yw nid a problem? (Esboniad isod)
Os y solenoid coil problem, cyntaf gwirio y gwifrau i gwel if mae a false connection, or byr cylched ffenomen, if there yw problem ar y llinell yw y solenoid coil llosgi allan, chi can tynnu y solenoid falf gwifrau, defnyddio amlfesur i mesur, if the Open Circuit, The solenoid falf coil llosgi allan. Rhesymau yn coil lleithder, cas inswleiddio yw nid da a magnetig gollyngiadau%, canlyniad yn yn y coil a llosgi, felly atal glaw o mynd i mewn y solenoid falf. Yn ychwanegu, y gwanwyn yn rhy caled, y ymateb grym yn rhy ychydig turns o y coil, nid digon sugno gall hefyd gwneud y coil llosgi.
Second, if the coil is good, it is the solenoid valve itself. Generally can be adjusted manually with a word from 1 to 0 position, so that the valve is open, if it can be opened to show that it is indeed a coil problem, a new coil can be, if you can not open, remove the solenoid valve to see if the spool stuck, or there is a miscellaneous particles blocked, cleaned correctly should be used with CCL4, but taking into account the site is not in a condition, then you can use gasoline, there is no water can be used to clean up the site instrumentation gas blow-drying, remove the solenoid valve, and then the solenoid valve itself, the solenoid valve itself, the solenoid valve itself is not a problem. After cleaning, you can use on-site instrumentation gas to blow dry, when you dismantle it, be sure to remember the order of parts, if you do not pay attention to it, it is very easy to make a mistake when installing, the order of remembering the wrong even if you clean the solenoid valve, even if the solenoid valve is already through it is still not open!
