Problems solved by technology

[0002] In coal liquefaction, with the operation of the coal liquefaction reactor and the circulating pump, the sealing performance between the coal liquefaction reactor and the circulating pump sealing surface will become worse and worse, which requires grinding and repairing of the sealing surface to improve the sealing performance. The sealing performance of the sealing surface, the current grinding tool, when the grinding tool and the workpiece to be ground are assembled and connected to the grinding ring, it is impossible to check, check, and the working conditions during grinding at any time, and it is impossible to adjust the synchronization between the grinding tool and the sealing surface of the reactor. Axiality, the problem of being unable to accurately control the size of the grinding advance, and the problem of overloading and reducing the life of the grinding tool due to the unevenness of the surface to be ground during the grinding process and inconsistent resistance everywhere

Abstract

The invention relates to the technical field of grinding tools, and discloses a grinding tool comprising a grinding part (1), a first drive unit (2) capable of driving the grinding part (1) to rotate, and a A buffer part (3) between a drive unit (2) and the grinding part (1), the buffer part (3) is set to enable the grinding disc (11) to recede axially to reduce the working resistance and reset the grinding disc (11) after the overload is lifted. During the grinding process, it can effectively prevent overloading and jamming and protect the grinding tools.

Description

technical field [0001] The invention relates to the technical field of grinding tools, in particular to a grinding tool. Background technique [0002] In coal liquefaction, with the operation of the coal liquefaction reactor and the circulating pump, the sealing performance between the coal liquefaction reactor and the circulating pump sealing surface will become worse and worse, which requires grinding and repairing of the sealing surface to improve the sealing performance. The sealing performance of the sealing surface. With the current grinding tools, when the grinding tool and the workpiece to be ground are assembled and connected to the grinding ring, it is impossible to check, check, and the working conditions during grinding at any time, and it is impossible to adjust the synchronization between the grinding tool and the sealing surface of the reactor. Axiality, the problem of inability to accurately control the size of the grinding advance, and the problem of overloa...
