Abstract
A combined-type sealing structure of a pump comprises a sealing body (1), a locking collar (2) and a pump shaft (9), wherein the locking collar (2), a pressure plate (3) and a plurality of oil seals (5) are sequentially arranged on the pump shaft (9) from the left to the right; the oil seals (5) are arranged in an oil seal seat (6); the sealing body (1) is arranged at the outer ring of the oil seal seat (6); the locking collar (2) and the sealing body (1) are in threaded connection; a sleeve (4) is welded at the outer ring of a small flange of the sealing body (1); a cooling water in-out port is formed on the sleeve (4); the sleeve (4) and the sealing body (1) form a cooling water tank; an oil cup (7) is arranged on a large flange of the sealing body (1); and a plurality of grooves are formed in the inner hole of the sealing body (1), and a plurality of lubricating through holes are formed in the oil seal seat (6) at the position corresponding to the grooves. The sealing structure is reasonable, decreases frictional force, improves sealing performance and prolongs service life.
Description
Technical field:
The utility model relates to industrial pump, refers more particularly to a kind of combined seal structure of pump.
Background technique:
Traditional Sealing used for pump generally adopts mechanical seal or packing seal, and the mechanical seal sealing is reliable, applied widely, but one-time investment is high, installs with replacing cumbersome; Packing seal structure is simple, cost is low, but working life is short, sealability is not so good.When pumping was corrosive the medium of impurity particle, mechanical seal was worn and torn easily, and filler leaks easily.
Summary of the invention:
Order of the present utility model provides a kind of surface friction drag that reduces, and improves the combined seal structure of sealability and the pump in working life.
The utility model is achieved in that the combined seal structure of pump, comprise seal, retainer, pump shaft, it is characterized in that: described pump shaft from left to right is disposed with retainer, pressing plate and several oil sealings, oil sealing is arranged in the oil sealing base, the oil sealing base outer ring is provided with seal, and retainer and seal are threaded connection, and the little flanged outer ring of seal is welded with cover, put and be provided with cooling water outlet and inlet, cover forms a cooling water tank with seal; Be provided with lubricating cup above the large flange of seal; The seal endoporus is provided with several grooves, and oil sealing base respective slot place is provided with several and lubricated uses through hole, and described oil sealing and pump shaft contacting point are provided with one section conical surface.
The utility model is rational in infrastructure, has reduced surface friction drag, has improved sealability and working life.
Description of drawings:
Fig. 1 is the utility model structural representation.
Among the figure 1, seal, 2, retainer, 3, pressing plate, 4, cover, 5, oil sealing, 6, oil sealing base, 7, lubricating cup, 8, phenyl tetrafluoride pad, 9, pump shaft.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
With reference to accompanying drawing, the combined seal structure of pump, comprise seal 1, retainer 2, pump shaft 9, it is characterized in that: described pump shaft 9 from left to right is disposed with retainer 2, pressing plate 3 and several oil sealings 5, and oil sealing 5 is arranged in the oil sealing base 6, and oil sealing base 6 outer rings are provided with seal 1, retainer 2 is threaded connection with seal 1, seal 1 little flanged outer ring is welded with cover 4, is provided with cooling water outlet and inlet on the cover 4, and cover 4 forms a cooling water tank with seal 1; The seal 1 large lubricating cup 7 that is provided with above the flange; Seal 1 endoporus is provided with several grooves, and oil sealing base 6 respective slot places are provided with several lubricated through holes of using, and described oil sealing 5 is provided with one section conical surface with pump shaft 9 contacting points.During implementation, realize sealing by linear contact of special oil sealing and running shaft, grease-added to oil sealing from seal groove and oil sealing base by lubricating cup between oil sealing and the oil sealing, reduced surface friction drag, improve sealability by increasing oil sealing quantity.The outside logical cooling water of seal is taken away oil sealing and the fricative heat of axle, the working life of having improved oil sealing.
