Valve positioner is an essential part of many industrial environment, sometimes in life there are a wide range of applications, because more and more people know the valve positioner, there are more and more people use, so there will be the occasional unprofessional workers don't know how to deal with the problems of the equipment, this article will first introduce how should when valve positioner output to screen,
Please follow the steps below:
Is there something stuck between 1, check the armature and the coil;
2, check the balance spring debug location is reasonable;
3, check that the baffle with nozzle position is appropriate;
4, check the coil electromagnetic component;
5, check the signal wiring is correct;
6, see if have feedback pole falls off and air pressure within the prescribed scope,

Valve positioner output such as tortoise speed screening methods:
Open the valve locator before cover: 1, 2 check baffle position, will check diaphragm 3 Fang Daqi apart, have without block 4, constant orifice check feedback spring elasticity,
Open the cover of a valve positioner: listen to the voice, by listening to the voice of the check whether there is any leakage on the input air chamber; The air pipe with and without crack cause leakage, can judge the naked eye,

Above is the common problem check method, the subsequent we will update related knowledge of industrial control small, welcome attention!
