Industry Information
Common faults and causes of pressure gauges in operation
2012-11-20 15:45:46
First, the pressure gauge has no instructions
Reasons: 1. The shut-off valve on the pressure guiding tube is not opened 2. The pressure guiding tube is blocked 3. The spring tube joint is blocked 4. The spring tube is cracked 5. The center tooth and the fan tooth are worn and cannot be engaged
Second, the reason for the large pointer jitter: 1. The pressure of the measured medium is too large 2. The position of the pressure gauge is too shaken

3. Reasons for the beating or sluggishness of the pressure gauge pointer: 1. The friction between the pressure gauge pointer and the scale or the surface glass; 2. The central gear shaft is bent; 3. There is dirt at the meshing of the two gears; 4. The screw between the connecting rod and the fan gear is not flexible.

4. After removing the pressure, the pointer cannot return to zero. Reasons: 1. The pressure gauge pointer is bent 2. The hairspring force is too short; 3. The pressure gauge pointer is loose 4. The transmission gear has friction

Fifth, the pressure indication is wrong or uneven.
Reasons: 1. The spring tube is deformed or malfunctioning 2. The free end of the spring tube and the sector gear, the transmission ratio of the connecting rod is not adjusted properly

Reasons for transmission ratio misalignment: 1. Improper commissioning

7. Reasons for the low indication: 1. Improper transmission ratio 2. Leakage of the spring tube 3. There is friction in the pointer or transmission mechanism 4. Leakage of the pilot line

The pointer cannot indicate the upper limit scale
Reasons: 1. Small transmission ratio 2. Improper movement position 3. Improper spring tube position
