Pressure gauge needle jumping

Pressure gauge in the process of industrial process control and technology measure, due to the flexibility of general pressure gauge sensor has high mechanical strength and production convenient, installation simple reading convenient features, makes the general pressure gauge is more and more widely used. General pressure gauges for measuring no explosion, crystallize, solidify, for copper and copper alloy non-corrosive effect of the liquid, gas or steam pressure and vacuum. Pressure gauge is a sensitive element (by table Bourdon tubes, bellows, bellows) Elastic deformation, the pressure deformation by the transformation of movement in table to Pointers, cause the hands to display the pressure. Pressure gauges in use jump needle? Below small make up for you to analyse the reason: why a pointer and dial friction maintenance methods: straightening pointer, adjust the spacing. Reason two, center shaft bending repair methods: gear shaft straightening or replace gear shaft. Three reasons have defiled, the gear meshing repairs method: wash the gear. Reason four, adjusting screw inactivity value for maintenance methods: down thin thickness of the connecting rod. According to the small make up the above introduction, we don't have to worry about pressure gauge needle jumping.
