Embodiment
Be clearly and completely described to the technological scheme in the embodiment of the present invention below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.
A kind of sealing configuration of low-pressure injection molding dedicated gear pump torque input shaft, a kind of sealing configuration of low-pressure injection molding dedicated gear pump torque input shaft is provided, as Fig. 1, shown in Fig. 2 and Fig. 3, comprise gear pump and spring energy-storage seal ring 5, described gear pump comprises the first gear pump sheet 1, second gear pump sheet 2 and Three gear pump sheet 4, gear 3 is provided with in the second described gear pump sheet 2, gear pump torque input shaft 7 and gear minor axis 9 is provided with in described gear pump, described spring energy-storage seal ring 5 to be arranged on gear pump torque input shaft 7, described gear pump torque input shaft 7 is provided with pump shaft end cap 6 in one end of gear pump, described spring energy-storage seal ring 5, gear pump torque input shaft 7 and pump shaft end cap 6 coordinate fixing, one end of described gear minor axis 9 is provided with plug 8.
Described spring energy-storage seal ring 6 comprises spring energy-storage seal ring body and energy-storaging spring 11.Described spring energy-storage seal ring body comprises endoporus sealing labial surface 10, cylindrical sealing labial surface 12 and pump sheet end face seal face 13.Described energy-storaging spring 11 is arranged between endoporus sealing labial surface 10 and cylindrical sealing labial surface 12.Described spring energy-storage seal ring body is made up of ptfe composite.
Spring energy-storage seal ring is a kind of PTFE(teflon) composite material, and adopt U-type groove built with the high-performance sealed part of special spring, system fluid pressure is added by suitable spring force, sealing labial surface is ejected, and push down by the metal covering sealed gently, to generate very excellent sealing effect.The actuating effect of spring can overcome the slight eccentricity in metal combination face and the abrasion of sealing labial surface, and continues the sealability of possessing expection.With the end cap of pump shaft, the end face of spring energy-storage seal ring is tightly pushed down, sealing while defining endoporus sealing labial surface and cylindrical sealing labial surface simultaneously.The seal ring of this composite material can long-term work at 250-300 DEG C, solve the common problem troubling this industry for a long time.
The beneficial effect of the sealing configuration of low-pressure injection molding dedicated gear pump torque input shaft of the present invention is: the sealing configuration of low-pressure injection molding dedicated gear pump torque input shaft of the present invention adopts ptfe composite to make, sealed by many-sided simultaneously, there is excellent sealing effect, and wear-resistant, long service life.
The foregoing is only embodiments of the invention; not thereby the scope of the claims of the present invention is limited; every utilize description of the present invention to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
