Bush pumps pump pump boiler circulating pump bearing materials are usually softer pump bearings, inner cylindrical surface grinding method should not be used for machining the bearing points, you can use boring, Diamond boring, scraping or grinding process. Should not be used with a shaft diameter grinding with research methods, but you should use a special size and pore size of the bush like a pestle. Scrapers used for part of the tile bearing, with a wide blade scraper scraping machine. When manual scraping, scratches should be shallow. The complex shape of the inner surface of the bearing bush change should be using a special method of boring this sphere watt maximum mechanical parts used in the cement according to the specific shape of the situation by observing their burning bush found, the cause of problems is spherical bush improper use, but the problem is that in the assembly session. Many people think that contact with the spherical seat tile and tile to a full range of contact should be better, but in fact this is not true, but because of long-standing friction produces heat and burning may occur.
