Several skills to sand making machine maintenance

The vsi6x sand making machine is the main equipment for producing machine-made sand. Bearings, rotors, impact blocks and impellers are the key components of the sand making machine. In the process of use, the correct operation of the sand making machine is very important, and the maintenance and maintenance of key components is also very important. Regular maintenance and repairs are scheduled to give full play to the greater performance of the equipment and increase the service life of the sand making machine.

1. Bearing

The shaft of the sand making equipment bears the full load of the negative machine. Regular lubrication directly affects the service life and operating speed of the equipment, so regular lubrication is required, and the injected lubricating oil must be clean, the seal must be good, and the lubricating oil must be used in strict accordance with the instructions standard.

The bearing is not smooth, which directly affects the service life and efficiency of the sand making machine. Therefore, we need to pay special attention when using it, and check and maintain it regularly. The general approach is as follows:

The sand making machine needs to add lubricant to the bearing when it works for about 400 hours; if it runs for 10 hours a day and starts up for 20 days a month, it will be added once every 2 months; if it is not used for a long time, it must be first before turning on the machine. Lubricate the bearings of the sand making machine;

After running for 2000 hours, carry out dust removal and cleaning of the bearing; after conversion, if it has been used all the time, it will be cleaned once every six months (6 months);

After 7200 hours of operation, new bearings need to be replaced; those that are used frequently should be replaced once every 3 years, and those that are not frequently used should be replaced once every 4 years;

The bearing oil temperature is not easy to be too high. If it is summer, it is recommended that the continuous operation should not exceed 12 hours, and the machine can be shut down properly.

2. Rotor

The rotor is the component that drives the high-speed rotation of the sand making machine. In production, the top, inner side and lower edge of the rotor are easily worn out. Check whether the machine is running normally every day, and check whether the transmission triangle tape is tightened regularly. If it is too loose or too tight, it should be adjusted appropriately to ensure that the triangle tape should be grouped and matched, and the length of each group should be as consistent as possible. If the rotor is unbalanced during operation, vibration will occur, which will wear the rotor and rotor bearings.

3. Impact block

The impact block is a part of the sand making machine that wears severely during work. The cause of the wear is also related to the inappropriate material selection of the impact block, unreasonable structural parameters or inconsistent material properties. The impact blocks corresponding to different types of sand making machines will be different. It is necessary to ensure that the sand making machine and the impact block are matched with the corresponding models. Abrasion is also related to the hardness of the material. If the hardness of the material exceeds the bearing range of the sand making machine, the friction between the material and the impact block will increase, resulting in the wear of the impact block. In addition, the gap between the impact block and the counterattack plate should also be adjusted.

4. Impeller
The impeller is one of the important parts of the sand making machine, and it is also a fragile part. Protecting the impeller and improving its stability can not only effectively improve the working efficiency of the sand making machine, but also extend the service life of the sand making machine.

The direction of rotation of the impeller device should be counterclockwise from the feed port, otherwise the motor wiring position should be adjusted; the feed should be uniform and continuous, and the size of the river pebbles should be strictly in accordance with the equipment regulations. River pebbles with too large particles will cause the impeller to malfunction. Balance and wear the impeller; stop feeding when shutting down, otherwise it will cause the impeller to be crushed and damage the impeller; it is also necessary to check the wear of the impeller device regularly, and replace the worn impeller in time to ensure the normal operation of production.
