Shanghai packaging machine
ry of gas switch installed reversible motor repair;
For mechanical equipment, no need maintenance, packaging machine
ry, vacuum packaging machine has become the important assistant of food packaging, occupies an important position in the food packages installed.
with the improvement of packaging machinery automation, automatic vacuum packaging machine, stretch film packaging machine and gas switch installed more and more get the favour of enterprise;
Gas switch installed can take out the packing container by gas, into the inert gas to extend the shelf life and keeping fresh of the food, preserved food nutrients.
Capacitive reversible motor common faults
Automatic vacuum packaging mechanical and electrical capacitance of non-uniform clearance of reversible motor stator and rotor, bearing quality is bad or bearing wear, with the shaft vibration and sound in operation, serious when even to rotate the motor can't.
Automatic vacuum packaging mechanical and electrical capacitance reversible motor slowdown in the gear processing, assembly meshing is bad, or there is friction, make the motor rotation slowly or jitter, can't even turn.
Automatic vacuum packaging mechanical and electrical capacitance reversible motor for use for a long time not to clean and smooth, speed reducer with dust and dirt from the other, and thus lose lubrication, this will make the friction increase, reduce sensitivity, even can't turn the
The fault checking and removing the
Air vacuum packaging machine of reversible motor rotation: first, should check whether the stator winding circuit, circuit, if the winding should be open motor for inspection.
If open circuit in the outside of the coil, can again the good welding, coated with insulating paint and package (yellow silk, in case of short circuit.
If local coil short-circuit, insulation can be fitted, coated with insulating paint drying processing;
Such as short circuit area is too big, should be back around the same wire coil.
reversible motor automatic vacuum packaging machine, if there is no break, just check whether the rotor is stuck, stuck the reason may be due to the long operation time, shaft and bearing wear, and partly due to the deformation of shaft and the clearance between the rotor and stator is not uniform, or because of bad caused by the wear reduction gear meshing and the rotor shaft end pinion and rotor shaft installation is not strong.
If it is found that the rotor shaft and bearing loose due to wear and tear, can replace the bearing or replace small rotor shaft;
Another shaft by the wear and tear will also be part of the chrome plating, then the part of the plating inscription mill to cooperate with bearing size.
If the rotor shaft deformation, can be on a lathe or small presses,
Use thousand if found stuck or friction reducer phenomenon, this basically is the reduction gear and shaft wear loose or shaft and deformation table)
Correction to restore the original precision.
, can replace the worn gear and shaft.
Also may be not the small gear on the rotor shaft tightening up on the shaft and cannot drive the retarding mechanism, this is the place where it's easy to ignore, check discovered shall be binding.
Automatic vacuum packaging machine of reversible motor, because of the speed reducer gear and shaft sludge or lack of oil, increase the friction force and make the motor speed is reduced, the sensitivity is reduced, the rotation is not flexible, so with detachable motor, wash clean with gasoline or other volatile oil, volatile after filling oil for gasoline.
Reversible motor rolling vacuum packaging machine, measuring excitation winding voltage, under normal condition should be about 150 v, if less than this number a lot, may be local short circuit in the winding.
Field winding in the concatenated normal on both ends of the capacitor voltage should be 220 ~ 250 v, if less than this value, could be capacitor leakage.
