Judgment method only need to use multimeter to measure motor leads are, and zero line, the resistance between the normal about l6O & amp; Omega; , such as the deviation is too big or too small coil has been burned. ( 2) Split phase capacitance volume is too large. 2, electric valve every analysis will melt broken guarantee: ( 1) Metal wire insulation damage motor coil, coil winding body contact and short circuit. Multimeter found comprised more than available. ( 2) Split phase capacitor lose effectiveness or breakdown, split phase capacitor was broken, the motor will not start, the multimeter easily seizing split-phase capacitance. Disposal method is to move the micro switch, with the valve stem position suits. If normal, seizing a current change in voltage circuits. Sometimes split phase capacitance volume is too large, starting current is big, will burn out, judgment method to choose with alternating current measuring its current value. Using the background is not good, the water to a short circuit or motor rotor death, motor coil heat, burn out. Disposal method for multimeter is seizing the zero volume, adjustable potentiometer resistance change or destroy. 2. The logo output stem lines or electric operator on stem line break. When regulator action, journey to zero and full, micro switch should be closed, the current does not flow through the machine, to try to take care of motor Marine valves, such as micro switch to open, the valve lever action has reached zero or full, still can not fracture micro switch, then the current electricity flow through machine. Comprised as follows: 1. Feedback signal and feedback coil break line. ( 3) Two micro switch position is not suitable. Q: a: electric regulator several common faults and disposal measures to electric regulator malfunction phenomenon is numerous, cite several common phenomena and disposal measures: 1, the motor does not turn the Industrial Valves is not action, as follows: ( 1) The motor coil burn out. 4, the valve can not stable: as the zero error, kill car body too loose, damaged or adjust potentiometer. Judgment way Nordic table of measuring winding resistance. 。 3. Any supply feedback circuit of power. Seizing the brake tightness degree. 3, a transmission, the regulator is in the midst of the whole paper or seated position. At a time when the motor has no way to turn, will make motor stalling a burn out. Notes to the order: The national standard) A, A: B: product name, model, nominal size medium and temperature, pressure range C: whether there is attachment, delivery time, and special requirements so that we can correct selection for you. Second, if the valve has been selected by design unit of our company model, please order according to the valves parameters directly with our sales center.
