Common Methods For Checking Whether Skf Bearing Grease Can Degenerate

Degenerate

In the process of using SKF imported bearings; Grease is very important If yes; The use of metamorphosed Degenerate grease; Not only can it not achieve the desired effect; It will also damage SKF imported bearings The following is an analysis of some common methods for checking lubricating grease

① Oil flow survey method

Take two measuring cups; In the meantime, one is filled with Degenerate lubricating oil to be checked; The other one is empty on the table; Lift the measuring cup filled with lubricating oil 30-40 cm away from the desktop and skew it;

Let the lubricating oil gradually flow into the empty cup; Observe their Degenerate activities; The lubricating oil with good quality shall be slender, uniform and continuous; If the oil flow is fast or slow; Sometimes large pieces flow down; The lubricating oil has degenerated

② Hand twisting

Twist the lubricating oil between thumb and index finger for repeated grinding; Better lubricating oil, less wear debris and no conflict; If you feel a greater sense of conflict such as sand between your fingers; It indicates that there are many Degenerate impurities in the lubricating oil; No more; Replace with new lubricating oil

Common Methods For Checking Whether Skf Bearing Grease Can Degenerate

③ Illumination method

On sunny days; Lift up the lubricating oil with a screwdriver; At an angle of 45 degrees to the horizontal Control sunlight; Investigate the condition of oil droplets; Under light; It can be clearly seen that there is no wear debris in the lubricating oil; Sustainable effects; If there is too much wear debris; Replace the lubricating oil

④ Oil drop trace method

Take a clean white filter paper; Drop several drops of oil on the filter paper; After the lubricating oil leaks; If there is black powder on the surface; There is a sense of astringency when touching with hands; There are many impurities in the lubricating oil; Good lubricating oil without powder; Dry and lubricated by hand; And yellow trace

Quenching the surface layer of parts by means of solid-state phase transformation and rapid heating is called surface heat treatment, commonly known as surface quenching. Including flame heating quenching, high (medium) frequency induction heating quenching, laser heating or electron beam heating quenching, etc.

The characteristics of these methods are: local heating and quenching of the surface, small deformation of the workpiece; Fast heating speed and high production efficiency; The Degenerate heating time is short, and the surface oxidation decarburization is very slight.

1) continuous vacuum dryer, which is developed from the characteristics of spray drying and freeze-drying. The working process is carried out in a Degenerate low-temperature environment. The dry environment should maintain a low-temperature state.

First, the equipment itself should be equipped with high-performance cooling parts. Second, the heat dissipation performance of the equipment itself is better, which requires that the performance of the bearing must meet the requirements of low-temperature resistance and high heat dissipation.

2) Vacuum disc continuous dryer is mainly used to dry heat sensitive materials, and its drying process is Degenerate carried out under negative pressure. In the processing process, due to the different space pressure,

the equipment may have a small amount of expansion and contraction changes, which will have a great impact on the equipment components for a long time, which requires the bearing to have higher toughness and the performance that the clearance can be adjusted freely in a small range.

To ensure that the above performance bearing products are purchased, it is necessary to further understand the bearing code interpretation.
