【 Jiaxing bearing small classroom 】 Several types of centrifugal compressor bearings, you know?

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Centrifugal compressor on the requirements of the bearing is safe and reliable, stable running, good vibration resistance, long service life. Were adopted at present domestic centrifugal compressor bearings are mostly belongs to the high speed light load fluid dynamic pressure sliding bearing lubrication. Commonly used on compressor bearings, which has two kinds of the radial and thrust bearings. 1, 1) radial bearing Round tile bearing has the advantage of simple structure, but the poor stability, is now rarely used. 2) Elliptic net tile bearing compared with circular tile bearing, its advantage is first and foremost, it has good stability, if under the shaft, shaking in the operation, such as moving upwards, the above gap become smaller, the oil film force of k, the following gap get bigger, the oil film pressure decreases, the two parts of component force change will reduce the journal back into its original position, the shaft running stability; Secondly, because of the large side clearance, along the axial flow of oil quantity is big, good heat dissipation, lower the temperature of the bearing; But the bearing capacity is low, because the upper and lower two oil film, power consumption is big, in the vertical direction vibration resistance is good, but in the horizontal direction vibration resistance is poor. 3) More oil wedge fixed bearing is bearing the direction vibration resistance is better, the bearing temperature rise is low, not easy to happen the oil film oscillation, is often used in the old compressor. 4) Tilting tile bearing compared with other bearing, its advantage is each piece of tile are free to swing, under any circumstances can become the best oil wedge, high-speed stability is very good, not easy to happen the oil film oscillation, widely used in the centrifugal compressor. Tilting tile bearing mainly made up of bearing body, on both sides of the oil seal and segment. 2, 1) thrust bearing M wedge, thrust bearing thrust tile direct contact between the base ring, is a single layer. When thrust tile thrust under, can automatically adjust the position of the thrust tile forming favorable oil wedge. The thrust plate on both sides of the division main thrust tile and vice thrust tile. Under normal circumstances, the axial force of the rotor by thrust plate through the oil film to the main thrust tile, then passed to bearing base ring. But in starting or reverse axial thrust may occur during load rejection. The thrust will be bear by vice thrust tile. Thrust tile side in contact with the rotor thrust plate lined with ba jin alloy. The thickness should be less than 1 - 1. 5mm。 And tilt in the direction of the rotation of the rotor, so check out through the rotor disc and the relative movement of the thrust tile surface, between them can form a bear axial thrust oil wedge. 2) Mirra ginsburg ray thrust bearing thrust tile has a block on the level, below the level. And then the base ring, belongs to the three layer structure. Thrust tile with cushion below the standard block, the next level block and the base ring. Adopts spherical pivot contact between them to ensure that the thrust tile, standard piece is free to swing, uniform load distribution. 25 copper commonly used thrust tile. The casting babbitt, alloy thickness for 1 - commonly 1. 5mm。 Thrust plate with gaps between thrust tile, the clearance work is often referred to as the total amount, generally is 0. 25 - 0. 40 mm, it can ensure the push plate of oil wedge formed between phase segment, under the axial thrust of the rotor. Lubricating oil from the bearing into the gap between the shell and the clearance between thrust tile and thrust plate. Discharge of oil is by centrifugal force thrust plate rotates, oil was thrown, from the top of the bearing seat. Mirra ginsburg ray thrust bearing has the advantage of uniform load distribution between tile, flexible adjustment, the deflection of the rotor can automatically compensate; Defect is complex, need a longer axial installation dimension.
