The water remote pressure gauge hands swing frequently do?
1, pointer rotation slow or jitterReason:1, the transmission parts of the clearance is too small, the transmission is not flexible, increase the gap, or add a little Watch Oil2, moving parts between the active parts of fouling, transmission is not working, cleaning, rust removal, in addition to dirt or replacement transmission3, the free end and connecting rod connection is not flexible, adjust the connection mode until flexible4, the pointer with the dial, table cover friction, correct the pointer, thicken the glass lining below2, the needle rotation is not smoothReason:1 、 the sector gear tilts to correct or replace the gear2, the needle axis bending, straightening needle axis3, plywood bending, correcting the flatness of plywood4, the pillar tilts, causes the upper and lower plywood not to parallel, correct the strut, the addition and subtraction washer, causes the splint parallel3, pointer jitter bigReason:1, measured medium pressure fluctuations, close the valve opening2, the gear is not good, adjust the gear with the state3, the needle sleeve and shaft coordination is not good, adjust repair pointer sleeve and shaft clearance gap
1) without instructionReason: 1 the dirt in the pipe is blocked up and the dirt in the reed pipe is removed2, the sector gear and pinion resistance is too large, adjust the clearance to moderate3, two gear wear too much, unable to mesh, replace the two gear(2) the pointer is turning slow or beatingReason: 1, the transmission parts of the clearance is too small, the transmission is not flexible, increase the gap, or add a little Watch Oil2, moving parts between the active parts of fouling, transmission is not working, cleaning, rust removal, in addition to dirt or replacement transmission3, free end and connecting rod connection is not flexible, adjust the connection mode until flexible4, the pointer and dial, table cover friction correction pointer, thicken the glass lining below(3) the rotation of the pointer is not smoothReason: 1 fan gear tilt, correct or replace gear2 needle shaft bending alignment pin shaft3 plates, bending, correcting, flatness of plywoodThe 4 pillar tilts and causes the upper and lower clamping plates to be not parallel to correct the pillar, and the gasket is added and added so that the splint is parallel(4) the pointer jitter is largeReason: 1 medium pressure fluctuation, close the valve opening2, the gear is not fit well to adjust the gear matching condition3, the needle sleeve and the shaft do not match well, adjust the matching gap between the pointer sleeve and the shaft(5) the pointer deviates from the zero position and the error exceeds the allowable valueReason: 1. The fastening screws of the drive mechanism are loose and tighten the fastening screws2 fast buck, pointer bent or loose, tightly trimmed updated pointer and slow down3 spring tube has permanent deformation, reinstall the pointer, replace the new spring tube if necessary(6) indication is too highReasons: 1, transmission imbalance, re adjust the transmission ratio2 positive zero indication, partial Ambassador pointer to zero to negative zero allowed range
