In use process, failure is inevitable.
In addition to want to do a good job of protection and maintenance of the machine, and the correct use of vacuum packaging machine
However, there are some simple fault, we should learn to judge and deal with.
In particular, our technicians need to know something about the vacuum packaging machine
, in order to better service and maintenance of the equipment.
Each of the equipment failure and vacuum packaging machine in the same fault.
Today, I want to look at some simple fault vacuum packaging machine at home and abroad.
fault generally refers to the equipment or system in abnormal running process, can't meet the performance requirements for reservation, or parameter Settings exceed the prescribed limits.
A kind of phenomenon, may lead to loss of some or all of the equipment function.
Sometimes use & other;
This particular word.
If the equipment failure due to corrosion, also belong to failure categories.
Overall, the two are synonymous.
But strictly speaking, there is a difference between failure and error.
In general, all failures are false, but not all the mistakes are failure.
due to the diversity of the electrical and mechanical equipment, also have different failure forms.
Classification of the main fault forms are as follows:
According to the degree of fault in
the temporary fault classification.
A kind of heat pumping air into vacuum state, sealing, cooling the one-time completed function, apply to food, aquatic products, chemical raw materials, electronic components, precision parts and other products of vacuum sealing, can prevent oxidation, mildew, corrosion, moisture, but also extend the product with good quality fresh storage life of the machine.
this kind of failure has discontinuity, is the system under certain conditions by adjusting the system parameters or the operation parameters and the functional failure.
Take out of air inside the bag, to the expected after vacuum degree, complete sealing process.
Is used widely in food industry, vacuum packaging, all kinds of cooked products, such as chicken, ham, sausages, grilled fillet, beef jerky, etc;
Pickled products such as all kinds of pickled vegetables and soy products, dried fruit, etc are used more and more various need fresh food vacuum packaging.
After vacuum packaging of food freshness long, greatly extend the shelf life of food.
Without replacement parts to restore the normal function of the system.
permanent fault is caused by some parts damaged, must be replaced or repair in order to eliminate the fault.
This kind of failure can be divided into complete failure and partial failure, including local fault lead to loss of local functions.
According to the process of fault occurrence and development,
sudden fault in fault before there is no obvious sign of the early trials or it is difficult to carry on the forecast.
The failure time is short, usually is destructive, such as rotor faults.
Workers wrong operation equipment damage is caused by such failure.
in use process, due to fatigue, corrosion, wear and so on, the gradual decline in the performance of some parts, f value eventually exceed allowable values, this type of failure accounted for a large proportion of the, has a certain regularity.
The condition monitoring and fault prediction of early can effectively prevent the occurrence of this phenomenon.
Although the two types of fault is different, but they can be converted.
If parts wear to a certain extent, can also cause sudden fault, this is should be paid attention to in the operation of the equipment.
