Embodiment Construction
[0019] The structure and working principle of the friction ring of the mechanical seal device of the present invention will be further described in detail below with reference to the accompanying drawings.
[0020] Such as figure 1 , 2 , 3, 4 and 5, a friction ring of a mechanical seal device includes a ring body 1 in a pair of friction pairs, and the end face of the ring body 1 corresponding to the end face of the other ring body is provided with a number of evenly distributed The main groove 2 on the annular surface, there is a distance between the main groove 2 and the inner edge and the outer edge of the end face of the ring body 1, and a diversion groove 3 is respectively arranged between adjacent two main grooves 2, and the diversion groove 3 is respectively connected to the The ring edges on the same side of the end face of the ring body 1 are connected. The main groove 2 and the diversion groove 3 are arranged symmetrically and evenly according to the center of the ri...

The invention discloses a friction ring of a mechanical sealing device, comprising a ring body; a plurality of main grooves, which are uniformly distributed, are arranged on a ring body end surface corresponding to the other ring body end surface, and the inner edges and the outer edges of the main grooves and the ring body end surfaces are respectively separated by distances, diversion trenches are respectively arranged between two adjacent main grooves, the diversion trenches are respectively communicated with ring edges at the same side of the ring body end surfaces, the main grooves and the diversion trenches are symmetrically and uniformly arranged according to the circle centers of the ring bodies, the bottom parts of the main grooves are circular arc shapes, the bottom parts of the main grooves are close to the inner edges of the ring bodies, and side grooves are respectively arranged at two ends of the main grooves, close to one side of the inner edges of the ring bodies; the friction ring has the advantages that: the washed-away fluid can be pumped secondarily, the leakage amount can be effectively controlled, the opening force of a sealing end surface can be effectively improved, the operating stability of the equipment is enhanced and the service life is prolonged.
Description
technical field [0001] The invention relates to a mechanical sealing device for fluid dynamic pressure and static pressure sealing, in particular to a friction ring ring surface structure between mechanical sealing surfaces formed by a moving ring and a static ring in the mechanical sealing device. Background technique [0002] Mechanical seals are mainly used for shaft end seals of rotary equipment. Ordinary mechanical seals generally use liquid to block liquid or liquid to block gas. More advanced mechanical seals use dry gas seals and upstream pumping mechanical seals. Dry gas seals A relatively complex air source control system must be used, and there are very strict requirements on the pressure, flow rate and impurities in the air source. Therefore, the sealing device has a complex structure and high manufacturing and use costs, so it is widely used More troublesome. [0003] The traditional mechanical seal device with upstream pumping function mostly has better mechan...
