1. Illumination method on a clear day; use a screwdriver to pick up the lubricant; at a 45-degree angle to the horizontal plane. Check the sunlight; investigate the oil droplets; under the light; clearly see that there is no wear debris in the lubricating oil is outstanding; Continuous effect; if there is too much wear debris; should replace the lubricant.
2. Take a clean white filter paper by oil droplets; a few drops of oil on the filter paper; after the oil leaks; if there is a black powder on the outside; if there is a feeling of resistance by hand contact, it means that the impurities inside the lubricant have been Many; good lubricants are powder-free; they are dry and lubricated by hand; they are yellow.
3. The oil flow survey method takes two measuring cups; one is filled with lubricating oil; the other is empty on the table; the measuring cup filled with lubricating oil is lifted off the tabletop 30-40 cm and tilted; let the lubricating oil flow gradually In the empty cup; investigate the activity status; the quality of the lubricating oil should be slender, uniform, and continuous; if the oil flow suddenly and slowly; sometimes there is a large flow; then the lubricant has been transformed.
4. The hand rubbing method rubs the lubricating oil between the thumb and the index finger repeatedly; the better lubricating hand feels lubricity, less wear debris, no conflict; if you feel a large conflict between the sand between the fingers; Indicates that there are many impurities in the lubricating oil; it can not be reused; it should replace the new lubricating oil.

Steel Structure

Steel structure is composed of iron steel, is one of the main types of building structure. The steel structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel and steel plates. And the joints or bolts or rivets are usually used to connect the components or parts. Because of its lighter weight, and the construction is simple, widely used in large factories, venues, super high-level areas.

Specifications:

1. High material strength, light weight

2. Steel internal organizational structure is uniform, nearly isotropic homogeneous body.

3. Steel components facilitate the manufacture of the factory, site assembly. Factory mechanized manufacturing of steel structural components, high precision, high production efficiency, site assembly speed, short construction period. Steel structure is the most industrialized structure.

4. Steel structure construction building demolition almost no construction waste, steel can be recycled.
