First, determine the best opportunity for ina bearing repairs to roll the bearing operation to what kind of situation into the repair is better; this should be judged from the damage rules and characteristics of the ina bearing. The most used small and medium ina bearing damage; usually in sets Excessive fatigue and excessive wear of the ring or rollover. When the ina bearing rolls over the surface into wear for the third period; or has pitting and falling off; the ina bearing will quickly become ineffective; at this moment the damage of the raceway appearance has been Very serious; repair is very difficult; or has lost the repair value. But ina bearing before the above period; wear is more subtle; fatigue can only occur within a few micrometers to tens of micrometers of the outer surface of the tumbling appearance; therefore at this moment The machine will repair the bearing; it can obtain better repairing effect with a small value. In general, the repair period of the ina bearing-rolling bearing is for a period of time when the ina bearing has been operating properly; it has been fully utilized; It is most appropriate to enter the repair before the damage is presented. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
Second, the ina bearing repair opportunity determination method ina bearing can be repaired in detail; that is, the ina bearing has been fully utilized and the near-damage is presented in detail as follows:
1) Using the ina bearing working condition monitoring instrument, such as the iron spectrometer or SPM or I-ID 1 type bearing working condition monitoring instrument to judge the bearing working condition and the resolution of the ina bearing should be repaired; this is the most convenient and reliable Way. For example, when using the HD 1 type instrument; when the pointer is close to the danger zone by the warning area; and the pointer does not come back after adopting the method of improving the smoothness, etc.; it can be found that the problem of the ina bearing itself; at this moment, when the danger zone is not entered The ina bearing repairs. After all, it is far from the danger zone to start repairing; can be adjusted by experience. Use such instruments; can fully utilize the bearing operation potential; timely repair the ina bearing; and prevent the occurrence of the disease; it is safe and economical.
2) Use simple things to monitor in the case where the above instruments are not available; the operator can hold the round bar or the wrench and the like to conflict with the outer casing of the ina bearing; the ear is ashamed to monitor the sound of the ina bearing from the thing. Of course, the use of medical stethoscope modification can also be. Normal ina bearing work sound should be uniform, smooth and not sharp sound, but the normal ina bearing work sounds have a variety of intermittent, impact or sharp sound. First of all, you should get used to the normal ina bearing work sound, and then you can grasp the abnormal sound of the ina bearing work; then the accumulation of practical experience; and further can distinguish what kind of abnormal sound corresponds to what kind of ina Bearings are not normal appearance. There are many types of abnormal sounds in the bearings of the bearings; it is difficult to say; it is mainly based on experience accumulation.

2. The width and size of the goggles should suit the user's face shape;
3, lens wear rough, lens frame damage, will affect the vision of the operator, should be replaced in time;
4. Goggles should be specially used to prevent eye diseases;
5, the filter and protection of welding goggles should be selected and replaced according to the requirements of the specified operation;
A. Anti-cementing debris
Mainly used to prevent metal or sand debris and other mechanical damage to the eyes. Lenses and frames should be of solid construction and resistant to impact. The frame of TDAF001 sky shield is equipped with a shielding edge, and there shall be ventilation holes on it. Protective lens can choose toughened glass, adhesive glass or copper wire mesh protective lens.
B. Antichemical solution
Mainly used to protect the eyes from chemical damage caused by irritating or corrosive solutions. Ordinary flat lens can be used, and the frame should be covered to prevent the solution from splashing into. Usually used in laboratories, hospitals and other places, general medical glasses can be universal
