The bearings in all parts of the equipment are severely corroded, and the rust parts have a certain regularity. The bearing is mounted on the wall of the gearbox and consists of two rows of balls, one in the inside of the gearbox and one in the outside of the gearbox. The end face of the ball cylinder on the inside of the gear box is severely rusted; the end face of the ball cylinder on the outside of the gear box, except for a few rust, most of the smooth and non-corrosive signs. Fund Projects: Some of the special funds for the National Key Basic Research (G19990650) have rust on the circumferential surface of the side and the outer ball cylinder. The inner surface of the inner ball is more rusted and the outer side of the ball is less corroded. The ball on the inside is more rust than the bottom. There is also a similar corrosion condition in the bearing bush, and there is basically no sign of corrosion on the outside, and the inside is rusted and the other is smooth, which basically corresponds to the rust of the ball. Corrosion was also observed on the arc of the bearing frame base bearing frame, and the rust portion was on the upper side. The bottom of the bearing frame is bright and rust-free. Corrosion of the bearing frame, bearing bush and ball is indicated by the rust of the ball above the bearing. (Finish) Electric Portable Air Compressor
Electric portable screw air compressors are widely used in mining, hydropower, urban construction, shipbuilding and other industries. With the advantages of portable screw models, they are more consistent with lightweight, miniaturization of the development trend of screw compressors. New type electric portable screw air compressors have greater breakthroughs in terms of system and configuration than the traditional ones. They have achieved high efficiency, high stability and low energy consumption. It is more easy to operate and more convenient to maintain.
