In order to fully utilize the drum pump bearings and maintain their proper performance for a long time, regular maintenance (regular inspection) must be performed. By properly checking the drum pump regularly, it is important to detect the failure to prevent accidents in the early stage, which is very important for improving the productivity and economy of the drum pump.

1. When cleaning and removing the bearing of the barrel pump, first take a look at the appearance with photography. Also check the amount of lubricant remaining and sample the lubricant before cleaning the bearings.
1. The cleaning of the bearing is carried out by rough washing and fine washing, and a metal mesh frame can be placed on the bottom of the used container.
2. Remove the grease or adhesive with a brush or the like in the oil during rough washing. At this time, if the bearing is rotated in the oil, be careful that the rolling surface will be damaged by foreign matter or the like.
3. Slowly rotate the bearing in the oil during fine washing. Care must be taken. The commonly used cleaning agent is neutral non-aqueous diesel or kerosene, and a warm alkali liquid or the like is sometimes used as needed. Regardless of which cleaning agent is used, it is often filtered and kept clean. Apply anti-rust oil or anti-rust grease to the bearing immediately after cleaning.
Second, inspection and judgment In order to judge whether the removed barrel pump bearing can be reused, it is necessary to check its dimensional accuracy, rotation accuracy, internal clearance and mating surface, raceway surface, cage and seal ring. The inspection results can be judged by the use of a conventional bearing or a master bearing. The criteria for judging the drum pump vary depending on mechanical properties and importance, inspection period, and the like. If the following damage occurs, the bearing must not be used and must be replaced with a new one. Http://?420.html
1. Breakage and defects of bearing components.
2. Peeling of the rolling surface of the raceway surface.

Carbon steel forged blind Lap Joint Flange
Usually used the suitable for transport by sea, rail, air and other suitable for import and export customs clearance of free fumigation wooden box or free fumigation wooden pallets (precision products used the collision cladding coating layer in the packaging box , to ensure the goods safe enough)
Flange is an element connecting pipe to pipe, which used for connecting one pipe end to another. Equipment import and export for two devices is also connected to each other by a flange, gasket and bolt as a group of combined sealing structure of detachable connection. The flange is used in pairs, low-pressure pipeline can use Threaded Flange, pipeline pressure above four kilograms should use welding flange. Flange with different pressure is attached with different bolt.
