Embodiment Construction

[0022] The present invention will be further explained below in conjunction with specific embodiments.

[0023] A double-layer sealing device with damping energy mainly includes: a cooling system, a shock-absorbing bearing support mechanism, a main fixing body and a double-layer sealing mechanism.

[0024] Specifically, such as figure 1 As shown, the main fixed body is a main fixed round shaft sleeve, and its front end is a water-cooled disc 1. The shock-absorbing bearing support mechanism mainly includes a spring shock absorber 2, a sliding rail slider 3, a limit device 12, a spring compression bolt 14 and a support bearing. The fixed round shaft sleeve 4 is machined with positioning dimensions and threaded holes for installing the front shock-absorbing bearing support mechanism and the double-layer sealing structure, and 4-6 rigid support bearings 11 are distributed along the circumference of the fixed round shaft sleeve 4. The double-layer sealing mechanism mainly includes an i...

Abstract

The invention relates to a double-layer dynamic seal device with a damping function. According to an existing dynamic seal, a rigidity mechanism is adopted for support, huge noise is generated, and adverse influences are generated to the environment. In addition, most of existing dynamic seals adopt single-layer seal structures, and consequently the production efficiency is low. The double-layer dynamic seal device comprises a main fixing round shaft sleeve, and is characterized in that a front damping bearing supporting mechanism is arranged at the front end of the main fixing round shaft sleeve, a double-layer seal structure is fixed to the rear end of the main fixing round shaft sleeve and comprises an inner-layer seal mechanism and an outer-layer seal mechanism, and independent seal performance of the inner-layer seal mechanism and the outer-layer seal mechanism can be adjusted through an adjusting mechanism. The double-layer dynamic seal device solves the problems that due to sealring abrasion, continuous feeding cannot be achieved, and due to repeated vacuum pumping, the production efficiency is low.

Description

Technical field [0001] The invention relates to metallurgical equipment for manufacturing metal powder, in particular to a double-layer dynamic sealing device with shock absorption function in a plasma rotating electrode atomization powder making process. Background technique [0002] The plasma rotating electrode method is one of the methods for preparing high-quality metal powders. The prepared powders have low oxygen content, high purity, high sphericity, little / no hollow powder, and satellite sphere structure, which can be used for powder metallurgy near net forming In technology, such as the manufacture of aircraft turbine disks and gas turbine power plants, it can also be used in metal additive manufacturing (3D printing), laser green remanufacturing, surface modification and other processes. [0003] The raw material used for the preparation of metal powder by the plasma rotating electrode method is rods. The processing process is generally: raw materials are processed into ...
