Lubricating the bearing of the sewage mixer is a key step to ensure its normal operation and extend its service life. The following are the specific methods and precautions for lubricating sewage mixer bearings:

First, choose the appropriate lubrication method

There are two main lubrication methods of sewage mixer bearing: grease lubrication and oil lubrication. The choice depends on the specific working conditions and requirements.

Grease lubrication: Grease lubrication can simplify the bearing peripheral structure, suitable for some low-speed, light load or intermittent movement occasions. The filling amount of grease should be determined according to the bearing speed, bearing seat structure, space volume, grease grade and gas conditions of the use environment. In general, grease should be filled inside the bearing and the cage guide surface should also be filled with grease. For the space outside the shaft inside the bearing housing and the bearing, it shall be filled with 1/22/3 or 1/31/2 grease, depending on the limit speed.

Oil lubrication: Oil lubrication has advantages in terms of oil supply, heat dissipation and impurity removal capacity, and is suitable for high-speed, heavy duty or occasions where good heat dissipation is required. Oil lubrication methods include oil bath method, drip oil supply method, splash oil supply method, circulation oil supply method, jet oil supply method and spray oil supply method. The specific choice of which way, according to the bearing speed, working environment and lubrication requirements to determine.

Second, lubrication operation steps

Cleaning the bearing: Before lubrication, the dirt and impurities around the bearing should be cleaned first to ensure the lubrication effect.

Choose the right lubricant: According to the working conditions and requirements of the bearing, choose the right grease or lubricating oil.

Lubrication operation:

For grease lubrication, grease can be filled directly into the bearing and ensure that the cage guide surface is also greased. The amount of filling should be moderate, avoid too much or too little.

For oil lubrication, perform the corresponding operation according to the selected lubrication method. For example, in the oil bath method, the bearing part needs to be immersed in the lubricating oil; In the drip oil supply method, lubricating oil should be added to the bearing through the oil cup; In the splash type oil supply, it is necessary to use the rotating body to splash the oil on the bearing; In the circulating oil supply, the lubricating oil needs to be transported to the part of the bearing that needs lubrication through the oil pump.

Check the lubrication effect: After lubrication, the lubrication effect of the bearing should be checked to ensure that the bearing is fully lubricated.

Third, precautions

Regular lubrication: According to the working conditions and lubrication requirements of the bearing, the bearing is regularly lubricated. For occasions that require frequent lubrication, a reasonable grease port and outlet should be designed in order to replace the deteriorated grease.

Avoid contamination: In the lubrication process, it should be ensured that the lubricant is not polluted, so as not to affect the lubrication effect and service life of the bearing.

Temperature monitoring: During the operation of the bearing, the temperature of the bearing should be regularly monitored to ensure that it is within the normal range. If the temperature is found to be too high, check and handle it in time.

Follow the operating procedures: During the lubrication process, the operating procedures and safety specifications should be strictly followed to ensure the safety of personnel and equipment.

In short, lubricating the bearing of the sewage mixer is an important measure to ensure its normal operation and extend its service life. By choosing the right lubrication method, following the correct lubrication procedures and precautions, you can ensure that the bearings are fully lubricated and protected.
