The Machinery Section has introduced the \"Question of the Day\" feature, which not only helps to foster an active atmosphere for technical exchanges and guide the direction of such discussions but also provides users with financial rewards, enabling them to experience various cool features. 【Daily Question】Push-type mechanical seals are generally divided into single-spring and multi-spring mechanical seals; they are mechanical seals that use springs to apply pressure in order to compensate for wear on the sealing surfaces. The characteristics of a single spring (large spring) are (), while the characteristics of multiple springs are (). A. Suitable for high-speed operation B. Uneven pressure on the end surfaces C. The spring also serves as a transmission element D. Not suitable for high-speed operation E. Even pressure on the end surfaces F. The spring cannot serve as a transmission element. Answers: BCD, AEF. Based on the number of springs in the compensation mechanism, mechanical seals can be divided into multi-spring and single-spring types. The sealing mechanism that features multiple springs is known as a multi-spring mechanical seal ； A mechanical seal that contains only one spring in its compensation mechanism is called a single-spring mechanical seal. The multi-spring mechanical seal, also known as the small-spring mechanical seal, has a smaller axial dimension. The elastic force can be adjusted by changing the number of springs, resulting in a more uniform axial force. It is suitable for high-speed mechanical seals, but it is not appropriate for use in corrosive media. The single-spring mechanical seal, also known as the large-spring mechanical seal, has a relatively simple sealing structure. Some sealing types also use springs to transmit torque. Domestic seals make use of large springs frequently, but they cannot be used at high speeds. Requirements and tips for answering questions: Please reply with the answer you believe to be correct.
