Equipment seals for mine drilling and air extraction

Abstract

The invention discloses a sealing element for mine drilling air extraction equipment, which comprises: a support plate, and a sealing main body is arranged on the outside of the support plate, the sealing main body is fixedly connected with the support plate, and an external sealing body is installed on the outside of the sealing main body The detection bracket, the external detection bracket and the sealing main body are arranged in an integrated structure; the sealing installation part is arranged on the side of the external detection bracket close to the support plate, and the sealing installation part and the external detection bracket are arranged in an integrated structure ; leakage holes, which are arranged at the lower end of the external detection bracket, and the leakage holes are provided with four; the air pressure transmission sensor, which is arranged inside the sealing installation part, and the sealing installation part and the air pressure transmission sensor pass through the card Groove connection, which realizes that the sealing effect of the equipment used for mine drilling and air extraction is better, and it is in a harsh working environment for a long time. In the event of leakage, the staff can quickly know and avoid unnecessary losses.

Description

technical field [0001] The invention relates to the technical field of seals, in particular to a seal for mine drilling equipment for air extraction. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. The storage room temperature of the seals is best below 30 degrees Celsius to avoid high-temperature aging of the seals. Although the rubber and plastic seals are small, their functions make them an important part of the national economy such as national defense, chemical industry, petroleum, coal, transportation and machinery manufacturing. Basic components and accessories in major industries occupy a very important position in the development of the national economy. In recent years, with the rapid economic growth, the manufacturing industry of rubber and plastic seals has maintained...

Problems solved by technology

[0003] The sealing effect of the existing mine drilling and air extraction equipment seals is poor, and it is in a harsh working environment for a long time. Once a leak occurs, the staff cannot quickly know it, and it is easy to cause unnecessary losses.
