Description

Technical Field

[0001] The present invention relates to the technical field of mechanical fusion machines, and in particular to an air seal detection device for a mechanical fusion machine. Background Art

[0002] The mechanical fusion machine uses external mechanical force to make one material completely attached (or embedded) on another material, thus creating a new material. This new material contains the characteristics of two or more materials. The coating of nano powder is mainly achieved by mechanical fusion machine. However, because the nano powder particles are too small, the traditional sealing components cannot achieve complete sealing. After the machine body is used for a certain period of time, the particles of nano powder will enter the motor spindle and bearings through the gap of the sealing component, thereby increasing the friction between the spindle, bearings and other components. Since there is powder in the cavity (powder is corrosive), the powder will leak outward axially along the outer diameter of the wear-resistant sleeve during the rotation of the shaft, affecting the service life of the machine body. When the powder leaks into the matrix through the sealing component, it is impossible to know the internal situation of the mechanical fusion machine body in time during use, and the spindle will generate a lot of heat during the operation of the spindle.

Through the design of the cooling and detection component 4, a high-pressure environment can be formed in the cavity 33, so that the pressure in the cavity 33 is greater than the pressure in the cylinder 2, so that the powder will not leak out, forming airflow protection; the flow of air in the cavity 33, on the one hand, these gases can play a cooling role, when the main shaft 1 rotates, the wear-resistant sleeve 11 rubs against the lips of the first sealing component 5 and the second sealing component 6, which will generate heat and carry out the heat generated at the first sealing component 5 and the second sealing component 6.

By observing the substances in the air output after passing through the cavity 33, it is possible to judge whether there is a leakage at the first sealing component 5, avoiding the problem of difficulty in observing and identifying the sealing condition of the first sealing component 5 during use or under normal conditions.

[0018] like Figure 2 As shown, the cooling and detection component 4 includes an air inlet connector 41, an air inlet cavity 42, an air outlet connector 43, an air outlet cavity 44 and a filter 45.

Through the gas flow meter 410, the gas pressure in the cavity 33 of the air seal seat 3 can be controlled to be always greater than the pressure in the cylinder 2, thereby improving the protection effect. In the process of air output from the cavity 33, on the one hand, these gases can play a cooling role, the first sealing component 5 and the second sealing component 6, on the other hand, the dust particles will be carried away with the air flow, thereby avoiding further wear of the main shaft and the bearings. The air output from the cavity 33 enters the air outlet cavity 44, the air outlet connector 43, the filter 45 and the gas flow meter 410 at one time, and the impurities in the air are filtered through the filter 45, and the filter 45 is checked regularly. If there is powder in the filter 45, it means that the lip of the first sealing component 5 is worn and needs to be replaced in time, thereby avoiding the problem of difficulty in observing and identifying the sealing condition of the first sealing component 5 during use or under normal conditions.
