Bimetallic thermometer common failures and solutions

one Tube dirt deposition and block; Sector gear and small gear resistance is too large; Two gear wear too much, not mesh; Wash dirt spring tube, wire; Adjust the fit clearance to moderate; Change the two gear; two Transmission of fit clearance is too small, not flexible; 2. Transmission activity site had product between a corrupt, ineffective; 3. The free end connected to the connecting rod is not flexible; 4. Pointer and dial friction; Increasing the tolerance clearance, or appliance watch oil; 2. Cleaning rust removal, in addition to dirt or replacement drive; 3. Adjust the connection until flexible; 4. Correct the pointer, thickening glass lining below; 3. Sector gear tilt; Pointer shaft bending; Plywood bent; Strut tilt, cause splint is not parallel to the up and down; Correct or replace gear; 2. Alignment pin shaft; 3. Calibration plate straightness; 4. Correction pillar, add and subtract washer splint parallel; Four. Transmission mechanism of the fastening screw loose; Spring tube produce permanent deformation; Tighten the set screw. 2. Reshipment pointer, if necessary, replace the new spring tube; Five. Pointers can't indicate limit scale reasons: 1. Transmission ratio; 2. Inappropriate position of spring tube welding; Move the hinged bolts into; 2. To welding.
