Abstract
The invention discloses a tight positioning magnetic mechanical sealing element. A sealing cushion body is sleeved on a sealing static ring body; at least two linkage positioning grooves are formed symmetrically on an outer ring of a sealing movable ring body; the inner ring surfaces of the linkage positioning grooves are provided with pressure-regulating positioning holes; at least four magnetic beads are arranged symmetrically on a face, which faces a tight positioning ring body, of the sealing movable ring body; the tight positioning ring body is provided with a tight positioning bolt for installing and positioning; meanwhile, a face facing the sealing movable ring body is provided with opposite supercharging magnetic balls which correspond to the magnetic balls on the tight positioning ring body; the tight positioning ring body is provided with a projecting linkage positioning step which is used together with the linkage positioning grooves; the linkage positioning step is provided with a pressure-regulating positioning bolt which corresponds to the pressure-regulating positioning hole in the sealing movable ring body. The tight positioning magnetic mechanical sealing element is simple in structure, and can be widely applied to the fields of various types of pumps, kettles, ventilators, blowers, speed reducers, gearboxes and the like.
Description
Technical field
The present invention relates to technical field of sealing technology, especially a kind of positioned magnetic mechanical seal part that presses closer.
Background technique
Sealing is the kernel component of pump class most critical; the validity height of Sealing is directly determining the length problem in working life of pump; seal holder part part positioning precision height directly affects wearing and tearing degree of one-tenth and the working life of sealing ring surface, mostly mechanical seal because the sealing positioning precision is poor, spring force is inhomogeneous, frequently open, the undesirable element such as shutdown causes sealing ring surface serious eccentric wear to occur and leakage liquid.
Summary of the invention
In order to solve, existing machinery sealing positioning precision is poor, spring force is inhomogeneous, the problem of easily serious eccentric wear, the invention provides a kind of positioned magnetic mechanical seal part that presses closer, not only positioning precision is high, and removes spring structure, adopts magnetic force mechanism to place the eccentric wear phenomenon occurs.
Described a kind of positioned magnetic mechanical seal part that presses closer, by the sealing pad, stationary seal ring body, moving sealing ring body, press closer the location ring body connect to form successively, it is characterized in that: the sealing pad is sleeved on the stationary seal ring body, be symmetrical arranged at least two interlock locating slots on the outer shroud of moving sealing ring body, on the inner ring surface of interlock locating slot, the pressure regulation positioning hole be set; The moving sealing ring body is symmetrical arranged at least four magnetic beads on the face that presses closer the location ring body; Press closer on the ring body of location and be provided with and press closer holding down bolt for location is installed, at the face towards the moving sealing ring body, opposed supercharging magnetic bead corresponding with the magnetic bead on pressing closer the location ring body is set simultaneously; Press closer the location ring body and projection interlock positioning step is set is used in conjunction with the interlock locating slot, and it is corresponding with the pressure regulation positioning hole on the moving sealing ring body on the interlock positioning step, the pressure regulation holding down bolt to be set.
Described a kind of positioned magnetic mechanical seal part that presses closer, by the sealing pad, stationary seal ring body, moving sealing ring body, press closer the location ring body connect to form successively, it is characterized in that: shaft sealing can be set to the metal frame sealing, also can be set to 0 type seal with elastometic washer.
The invention has the beneficial effects as follows: not only simple in structure, and the balanced magnetic force that makes to press closer positioned magnetic mechanical seal has substituted the extremely unstable elastic force of mechanical seal spring, thereby extended the working life of sealed member, can be widely used in the fields such as all types of pumps, still, ventilator, blower, speed reducer, gear-box.
The accompanying drawing explanation
Fig. 1 is the positive perspective view of the present invention; Fig. 2 is the back side of the present invention perspective view.
Wherein, 1. seal pad; 2. stationary seal ring body; 3. moving sealing ring body; 4. press closer the location ring body; 5. press closer holding down bolt; 6. magnetic bead; 7. shaft sealing; 8. pressure regulation holding down bolt; 9. opposed supercharging magnetic bead; 10. interlock positioning step; 11. interlock locating slot; 12. pressure regulation positioning hole.
Embodiment
As shown in Figure 1 and 2, sealing pad 1 is sleeved on stationary seal ring body 2, is symmetrical arranged four interlock locating slots 11 on the outer shroud of moving sealing ring body 2, on the inner ring surface of interlock locating slot 11, pressure regulation positioning hole 12 is set; Moving sealing ring body 3 is symmetrical arranged six magnetic beads 6 on the face that presses closer location ring body 4; Press closer on the ring body 4 of location and be provided with and press closer holding down bolt 5 for location is installed; At the face towards moving sealing ring body 3, opposed supercharging magnetic bead 9 corresponding with the magnetic bead 6 on pressing closer location ring body 4 is set; Press closer location ring body 4 and projection interlock positioning step 10 is set is used in conjunction with interlock locating slot 11, and it is corresponding with the pressure regulation positioning hole 12 on moving sealing ring body 3 on interlock positioning step 10, pressure regulation holding down bolt 8 to be set.
Working procedure: the present invention is as Fig. 1, shown in Fig. 2: press closer holding down bolt 5 and will press closer location ring body 4 precisions and be locked in exactly on pump shaft, by pressing closer common magnetic force that the opposed supercharging magnetic bead 9 of location on ring body 4 and magnetic bead 6 on moving sealing ring body 3 produce all on the seal ring friction surface that is urged to stationary seal ring body 2 of spoon, make sealing surface on moving sealing ring body 3 and the sealing surface on stationary seal ring body 2 be in contact with one another automatic-sealed, its moving sealing ring body 3 has the interlock positioning step 10 that presses closer setting on the ring body 4 of location to connect location, pressure regulation holding down bolt 8 cooperations of installing on its interlock positioning step 10 press closer holding down bolt 5 and regulate the pressure between moving sealing ring body 3 and stationary seal ring body 2, by the shaft sealing 7 arranged on moving sealing ring body 3, liquid and pump shaft are isolated, make shaft sealing 7 and pump shaft form a kind of slidably type seal, effectively prevent leak of liquid.
