Causes: 1. The pressure of the measured medium is large; 2. The installation position of the pressure gauge is greatly shaken. Causes: 1. The shut-off valve on the pressure guiding pipe is not open; 2. The pressure guiding pipe is blocked; 3. The dirt in the spring pipe joint is excessively deposited and blocked; 4. The spring pipe is cracked; 5. The center tooth and the fan tooth wear Too much to mesh. Third, the pressure indication error is not uniform. Causes: 1. The spring tube fails to deform; 2. The free end of the spring tube and the sector gear are adjusted improperly. Causes: 1. The pointer collided with the surface glass or scale; the center gear shaft was bent; 3. The two gears were contaminated; 4. The movable screw between the connecting rod and the fan gear was not flexible. Causes: 1. Pointer bending; 2. Short spring force; 3. Loose hands; 4. Drive gear has friction. Reasons: 1. Improper gear ratio; 2. Spring tube leaking; 3. Pointer or transmission mechanism has friction; 4. Pressure guiding pipeline leaks. Reasons: 1. Small transmission ratio; 2. Improper positioning of the movement on the base; 3. Improper welding position of the spring tube.

The common faults and causes of diaphragm pressure gauge during operation:
First, the pointer jitter.
Second, the pressure gauge has no indication.
Fourth, the pressure gauge pointer jump or sluggish phenomenon.
5. After the pressure is removed, the pointer cannot be restored to zero.
Sixth, the transmission ratio is misaligned.
Seven, the pressure gauge indicates low.
Eight, the pointer cannot indicate the upper limit scale.
YN series diaphragm shock pressure gauge has good anti-vibration performance, especially suitable for working environment with mechanical vibration and medium pulsation. It can measure the pressure of liquids, gases, steam and other media without explosion hazard, without crystals, without solidification, and without corrosive effects on copper alloys.
