Vertical impact breaking sand machine is a very important equipment in the sand aggregate industry, and the impeller is the core of the vertical impact breaking. The maintenance and maintenance of the impeller is related to the service life and efficiency of the sand making machine. In this paper, the maintenance of the impeller of sand making machine is simply sorted out for the reference of users.
Impeller assembly is the main wear parts of equipment, therefore, the key to impeller maintenance is to check and replace the wear parts. When the wearing parts of the equipment can not meet the production of the next shift, they must be replaced, otherwise it will lead to serious damage. The main parts are as follows:
1, check wear-resisting body: wear-resisting body alloy in the inner position or the most serious wear position wear up to 95%, must be replaced.
2, check the chute plate: when the worn chute plate can not effectively protect the screw head, it is necessary to replace the chute plate.
Note: when replacing the main and secondary wear-resisting bodies and the slip plates, the weight of the three groups must be the same to ensure the balance of the impeller.
3, check the upper and lower runner lining plate: if the thinnest position of the upper and lower runner lining plate is only 3-5mm, it must be replaced.
4, check the cloth cone: when wear to the head of the screw in the vertebral body, or the thickness of the thinnest place is only 3-5mm, it should be replaced immediately. ,
5, the material port wear: the most likely to occur in the position of the launching port, when the thinnest place is only 3-5mm, should be replaced. Note that the material mouth has three wear position cycles, when a position wear period is used, it can be rotated by an Angle, so as to maximize the life span.
6. Check the baffle plate and the central feed pipe. The part of the central feed pipe extending into the feed port should be replaced when worn out. The retaining plate is the core part of the impeller. Regular replacement can extend the life of the wear-resisting body to the maximum extent.
7. Check the outer edge of the impeller upper disc and the outer edge of the lower disc, as well as the impeller upper disc anti-wear plate.
