Abstract
The utility model discloses a main shaft sealing device of a vertical centrifugal machine. The main shaft sealing device comprises a main shaft sleeve (1), a space ring (2), a sealing ring (3), an upper gland (4), a bearing (5), a bearing block (6) and a main shaft (7), wherein the main shaft sleeve (1) is installed on the main shaft (7), the main shaft (7) and the bearing (5) are installed in the bearing block (6), the sealing ring (3) and the space ring (2) are installed in the upper gland (4), air inlets (8) are arranged on the space ring (2) and the upper gland (4), the sealing ring (3) is made of modified polytetrafluoroethylene materials, and a ceramic coating is sprayed on the outer surface of the main shaft sleeve (1). According to the main shaft sealing device of the vertical centrifugal machine, the service life of the sealing ring is long, the maintenance period is long, and the using cost is lowered.
Description
Technical field
The utility model relates to a kind of main shaft sealing device, especially relates to a kind of vertical centrifugal machine main shaft sealing device.
Background technology
Centrifuge is a kind of separation machinery that is used for industrial Separation of Solid and Liquid; Through rotating the centrifugal force that produces at a high speed; Reach a kind of equipment of solid phase and liquid phase separation, in use contact with gas with corrosive liquids for a long time, must guarantee the validity at main shaft seal place reliably; Guarantee the centrifuge operate as normal, prolong maintenance period; Present most of producer adopts conventional backbone sealing ring as main shaft seal, but backbone sealing ring is easy to wear, and life cycle is short, and maintenance period is short, and sealing validity is poor.
Summary of the invention
The purpose of the utility model provides a kind of vertical centrifugal machine main shaft sealing device, can solve the problem of the technology that main shaft seal service life is short, reliability is low.
The problem of the required solution of the utility model is to realize through following technical scheme: comprise collar bush, spacer ring, sealing ring, upper press cover, bearing, bearing block and main shaft; Collar bush is installed on the main shaft; Main shaft, bearing are installed in bearing block inside, and sealing ring and spacer ring are installed in upper press cover inside, it is characterized in that spacer ring and upper press cover are provided with air inlet; Sealing ring is the modified Teflon material, collar bush outer surface spraying ceramic coat.
The beneficial effect of the utility model is: the sealing ring wearability is good, and long service life is multi-sealed, and sealing reliability is high.
Description of drawings
Below in conjunction with accompanying drawing the utility model is done further explanation:
Accompanying drawing 1 is depicted as the structural representation of the utility model
1. collar bushes, 2. spacer rings, 3. sealing rings, 4. upper press covers, 5. bearings, 6. bearing blocks, 7. main shafts, 8. air inlets among the figure.
The specific embodiment
Can know that by accompanying drawing this vertical centrifugal machine main shaft sealing device comprises collar bush 1, spacer ring 2, sealing ring 3, upper press cover 4, bearing 5, bearing block 6 and main shaft 7; Collar bush 1 is installed on the main shaft 7; Main shaft 7, bearing 5 are installed in bearing block 6 inside, and sealing ring 3 is installed in upper press cover 4 inside with spacer ring 2, and said spacer ring 2 is provided with air inlet 8 with upper press cover 4; Sealing ring 3 is the modified Teflon material, collar bush 1 outer surface spraying ceramic coat.
This vertical centrifugal machine main shaft sealing device, with sealing ring 3 and spacer ring 2 overlapping upper press cover 4 inside that are installed in, collar bush 1 is installed on the main shaft 7; Collar bush 1 contacts with sealing ring 3, and main shaft 7 drives collar bush 1 rotation, and upper press cover 4, sealing ring 3 are installed on the bearing block 6 to static; Air inlet 8 feeds pressure-fired gas, is injected in the middle of the sealing ring 3, in 3 air chamber that form a pressure-fired of sealing ring; The lip limit and the collar bush 1 of sealing ring 3 are fitted tightly, and the outside liquids and gases of sealing device can not get into sealing device, and sealing is reliable; Long service life has prolonged maintenance period, has reduced use cost.
Obviously; The foregoing description of the utility model only be for explain clearly that the utility model does for example; But be not used for limiting the scope of the utility model; All technical schemes that are equal to also belong to the category of the utility model, and the scope of patent protection of the utility model should be limited each item claim.
