Date: 2019-06-09      Hit: 353

Common symptoms and causes

1, failure phenomenon: leakage at the sealing surface. Cause: loose screw thread; sealing surface damage. Remedy: re-tighten the screw; re-grinding polished sealing surface. 

2, fault phenomenon: there is a leak at the valve. Failure: the stem (pin), valve port sealing surface damage. Remedy: repair, replace the stem (pin), valve port. 

3, the failure phenomenon: external magnet rotating inside the magnet does not turn the motor current decreases. Cause: too high temperature within the reactor, cooling circulation, temperature inside the magnet due to magnetic faded. Hydrogenation reaction, sets of cracks within the magnet, the magnet inside the expansion. Remedy: notify suppliers, to replace the internal magnet. 

4, failure phenomena: magnetic coupling with friction inside the transmission noise. Cause: bushings, bearings wear, the gap is too large, rotating magnet inside the beating occurs. Remedy: Contact with suppliers, replacement bearings, bushings.
