| Problems with the pressure gauge during use |
| 2011-10-27 16:51:08 |
，目前市场上的压力表主要部件是由弹簧管、接头、机芯组成。 As we all know , the main components of the pressure gauge on the market are composed of spring tubes, joints and movements. 4 种：比如氩弧焊接、铅锌焊接、白银焊接、特种焊接等等。 There are four main types of pressure gauge welding : such as argon arc welding, lead-zinc welding, silver welding, special welding and so on. The working principle of the pressure gauge is through the deformation of the spring tube; the fan teeth and the sun gear work (the movement) drives the pointer to display the pressure of the measured medium on the scale on the panel.
10 万次；而在压力表使用过程中会经常出现以下几个问题；例如： The pressure sheet reed tube currently works normally 100,000 times; the following problems often occur during the use of the pressure gauge; for example:
. 压力表 指针在管道或者设备卸压后不归到零位； 指针 . The pressure gauge pointer does not return to zero after the pipeline or equipment is depressurized;
. 另外压力表扇型齿再工作一段时间会出现磨损现象； ⑵ In addition, the pressure gauge fan teeth will wear for a period of time;
. 加隔离片解决压力表指针不回零位问题； (3) Adding spacers to solve the problem that the pointer of the pressure gauge does not return to zero;
. 离片扇型齿加宽 , 解决压力表接触面 , 抗磨损以达到使用寿命延长的功能； 离 . Widening of the fan-shaped teeth to solve the contact surface of the pressure gauge and anti-wear to achieve the function of extended service life
. Alas . The pointer of the pressure gauge increases the instantaneous pulse of the measured medium and pushes the pointer below the stop.
：压力表的心脏部件是压力表的机芯， 压力表损坏是由于机芯损坏而导致仪表不能正常使用；已经占 80% 以上。 Note : The heart part of the pressure gauge is the movement of the pressure gauge. The damage of the pressure gauge is caused by the damage of the movement and the instrument cannot be used normally; it already accounts for more than 80% .
By adding a limit pin spacer to the pressure gauge movement based on the existing instrument technology, this solves the problem of pressure gauge pointer jumping.
