From a variety of perspectives, sanitary pads machinery design of the pad have similar
classification methods, and there are usually the following classification
methods:
1. Categorize according to the reason
1) Deterioration: When the machinery and
equipment are put into operation, with the change of time, under the direct
influence of factors, the parts will be damaged, pulled out, and corroded. The
whole process of irreversible changes such as creep and the change of the metal
material structure, the whole process of this transformation will gradually
reduce the effect of sanitary pads machinery
design of the pad over time, which is called a common failure of deterioration.
2) Human factors: Because the management
plan is not perfect, it is applied in violation of application technical
specifications and maintenance technical specifications, such as overweight
applications, overspeed applications and applications that violate operating
procedures. The resulting abnormality is called human factor common failure,
also known as misuse.
2. Classified by duration
1) Temporary: The lack of some partial
effects produced in a very short period of time cannot be applied. After
production, there is no need to repair or replace parts, just adjust the
problem location and repair its missing function.
2) Sustainability: The lack of function of
machinery and equipment has been maintained until abnormal parts are replaced
or repaired, and then the professional ability of machinery and equipment can
be restored.
3. According to the speed of production
1) Sudden: due to the mutual effect of
various unfavorable conditions and coincidental external causes of the
machinery and equipment itself, when such effects exceed the extent that the
machinery and equipment can bear, it will occur quickly. The basic feature of
this is that it occurs at the same time as the facility: the change in situation
is related to the time period in which the machinery and equipment has been
used, and occurs suddenly without significant warning. The time of its
generation cannot be estimated by initial experiments and tests, so it is also
called undetectable.
2) Gradual: It is produced by the whole
process of various aging. The basic feature of this is that the time period of
its generation is related to the time period that sanitary pads machine has
been working. The longer the machine has been in use, the higher the
probability of occurrence. Common failures of this type of delay give the
probability of detection, so they are often referred to as detectable.
4, according to the characteristics of
classification
1) Function: Machines and equipment cannot
continue to perform their setting functions, such as the gas turbine cannot be
started due to an abnormality, the gasoline pump cannot provide oil, and the
reducer cannot transmit motion, etc. This problem is often caused by damaged or
stuck parts of the machine.
2) Main parameters: The main parameters
required by the machinery and equipment exceed the allowable specified values.
For example, the machining accuracy of the CNC lathe cannot meet the
requirements; the high efficiency of the transmission system is reduced; the
hoisting weight cannot meet the index value, etc. Questions about the main
parameters do not prevent the facility from running again, but according to the
specifications of the process data of the machinery and equipment, the
machinery and equipment are in a situation where the professional ability or
working ability of the disaster is significantly reduced.
5. Classified according to adverse effects
1) Destructive: the safety protection
equipment of the sanitary pads machinery, the braking system equipment of the transmission and other
important: serious consequences such as damage to the machinery and equipment
or casualties caused by the parts.
2) General: no non-dangerous factors such
as damage or casualty accidents are caused. However, such a problem is still
likely to lead to adverse effects such as reduced physical properties,
jeopardizing applications, discontinuing manufacturing, or causing approximate
property damage.
6. According to whether it is generated or
not
1) Specific: common faults that have
already occurred in machinery and equipment.
2) Potential: The machine and equipment
itself may have anomalies that are likely to occur. In the production process,
strictly abide by the application and maintenance technical specifications of sanitary pads equipment, and take
corresponding diagnostic measures, which will avoid potential abnormal
development trends and specific common failures.
There are various common failure methods of
sanitary pads machinery, but each of them must
be familiar to the actual operating staff and managers. Only by doing a good
job in maintenance and overhaul can the equipment achieve the best operating
state and reduce the Casualties, property damage.
