A quick method to release the pressure gauge of breakdown time: 2019 - 04 - Read 30 times: zero

A customer asked the little sister meeting lots of people before fault how to rule out and determine the pressure gauge? , now the meter huashi, share with everyone we summarize the method of operation of the common faults and pressure gauge and a pointer jitter reasons: 1. Test medium pressure; 2. Pressure gauge installation position of vibration. Second, the pressure gauge no order reasons: 1. Cutting pressure on the valve did not open; 2. Pressure pipe blockage; 3. Spring pipe joint in excessive dirt deposition and jam; 4. Spring tube cracking; 5. Center of tooth and tooth wear sector is overmuch, make its can't mesh. Three, uneven pressure indication error reason: 1. Spring tube deformation failure; 2. Spring tube free end and fan gear, connecting rod transmission ratio improper adjustment. Four, gauge pressure is to beat or dark phenomenon reason: 1. Pointers and glass surface or scale by friction; 2. Center gear shaft bending; 3. Two meshing gear and dirt; 4. Between link and fan gear active screw is not flexible. Fifth, after eliminate stress, pointer cannot return to zero. Reason: 1. Pointer bending; 2. The strength of wire short; 3. A pointer is loose; 4. Drive gear friction six, transmission ratio imbalance gauge indicates low reasons: 1. Transmission ratio imbalance; 2. Spring tube leakage; 3. Pointers or has friction transmission mechanism; 4. Pressure pipe leaking. Seven, Pointers can't indicate limit ratio reasons: 1. Transmission ratio; 2. Chassis location fixed improper movement; 3. Inappropriate position of spring tube welding.
