We have made targeted improvements to the problems of the original seal, including: (1) The size of the inner ring of the seal ring near the media side is reduced from the original 15-20 gap to 10-15. The main purpose of this is to minimize the amount of steam leaking into the compressor, as excess steam leaking into the compressor can cause styrene in the compressed gas to polymerize, causing equipment failure. (2) A smooth transition is made to the edge of the floating ring. Originally, during the installation of the compressor rotor, the shoulder of the shaft often damaged the edge of the seal ring. After the smooth transition of the sealing ring, the shoulder of the shaft will not damage the end face of the floating ring during the installation process. If the multi-oil wedge bearing oil film is not formed well and the oil supply pressure is unstable, it will cause oil film instability failure. Take the catalytic device YL3000 type flue gas turbine as an example. Its radial bearings are fixed four-oil wedge bearings, bearing structure and oil wedge principle. It can be seen that the oil wedge formed by the bearing blocks 1, 2, 3, 4 is like four damping springs, which improves the stability of the rotor. The bearing blocks 1, 2 are the main bearing bushes of the bearing, and the oil wedge formation is good or bad. Stability, at the same time, the bearing load direction is located between the lower two oil wedges, and its bearing capacity and oil film stability are directly different from the load acting directly on the lower oil wedge bearing. Therefore, the formation of the oil wedges of 1, 2 watts is directly related to the stability of the bearing oil film. According to the conventional bushing method, the contact areas of the blocks 1 and 2 are located at the lower ends of the lower part of the middle. At this time, the oil wedge convergence area and the diffuser area formed by the 1 and 2 watt blocks are relatively short, and the oil wedge is difficult to form. Or unstable. The correct bearing area of ​​the bearing bush should be two blocks close to the middle position. At this time, the oil film of the four bushings is the most stable. (a) bearing structure diagram (b) oil wedge principle diagram 2 fault treatment method For oil film instability failure of multi-oil wedge bearing, due to its high oil film stability, it is generally adjusted by adjusting lubricating oil pressure and oil temperature. If the effect is not obvious, the bearing clearance and bearing preload should be adjusted.
L(R) series pumps are cantilevered horizontal, centrifugal slurry pumps ,which are also called Light Duty Slurry Pumps. They are designed for continuous pumping of lower abrasive and lower density slurries. The liner and impeller of this type pump can be replaced with wear-resistant metal or rubber material. They are widely used in metallurgical, coal, mining, building material.
