The intuitive method is a method of
checking and judging adult diaper machine faults by looking, smelling,
listening and other means according to the external manifestations of
electrical faults, and can quickly know the simple faults of diaper machine. .
(1) Inspection steps for adult diaper
machine faults:
Investigation: Inquire about the situation
of the operator and the personnel present, including abnormal external
manifestations, general location, and environmental conditions when the
abnormality occurs. If there is no abnormal gas, open flame, whether the heat
source is close to the electrical appliance , whether there is corrosive gas
intrusion, whether there is water leakage, whether anyone has repaired it, the
content of the repair, etc.
Preliminary inspection: According to the
investigation, check whether there is any external damage to the electrical
appliance, whether the connection is open or loose, whether the insulation is
burnt, whether the fusing indicator of the spiral fuse jumps out, whether the
electrical appliance has water, grease, and switch position. Is it correct etc.
Test drive: After preliminary inspection,
it is confirmed that the failure will further expand and cause personal and
equipment accidents. Further test drive inspection can be performed. During the
test drive, pay attention to whether there are serious flashovers, abnormal
smells, abnormal sounds and other phenomena. Once found, stop immediately. Cut
off the power. Pay attention to check whether the temperature rise of the
electrical appliance and the action procedure of the electrical appliance meet
the requirements of the electrical equipment schematic diagram, so as to find
abnormal parts.
(2) Inspection method for adult diaper
machine faults:
Observe sparks: The contacts of electrical
appliances will generate sparks when closing or breaking the circuit or when
the wire ends of the wires are loose, so you can check the electrical problems
according to the existence and size of sparks. For example, when a spark is
found between a normally fastened wire and a screw, it means that the wire head
is loose or has poor contact. When the contacts of the electrical appliance are
closed or disconnected, the circuit will flash, indicating that the circuit is
connected. When two phases of the main contact of the contactor controlling the
motor have sparks and one phase has no sparks, it indicates that the contacts
of the first phase without sparks are in poor contact or the circuit of this
phase is open; the sparks of two phases of the three phases are larger than
normal, and the other phase If it is smaller than normal, it can be
preliminarily judged that the motor is short-circuited or grounded; if the
three-phase sparks are larger th an normal, it may be that the motor is
overloaded or the mechanical part is stuck. In the auxiliary circuit, after the
contactor coil circuit is energized, the armature does not pull in. It is
necessary to distinguish whether the circuit is broken or the mechanical part
of the contactor is stuck. You can press the start button. If there is a slight
spark when the normally open contact of the button is disconnected, it means
that the circuit is connected, and the problem is in the mechanical part of the
contactor; if there is no spark between the contacts, it means that the circuit
is open.
Action program: The action program of the
electrical appliance should meet the requirements of the electrical
instructions and drawings. If the electrical appliances on a certain circuit
act too early, too late or do not act, it means that the circuit or electrical
appliances are abnormal .
Using the intuitive method can not only
determine the simple abnormality, but also reduce the more complex adult diaper
machine faults to a smaller scope. Therefore, as a staff member, we must master
the diaper mechanical visual inspection method.
