Abstract
The utility model relates to a mechanical sealing device for a cauldron, which can be used for sealing a strong corrosion cauldron. The utility model comprises a stationary ring (7), a moving ring (9), and a lubrication tank (6) wound at the contact position of the stationary ring and the moving ring. The utility model is characterized in that the bottom part of a cavity body of the lubrication tank (6) is provided with a lubricating oil pipeline (17), and the lubricating oil pipeline (17) is communicated with a liquid level window (13) which is outwards connected. The situations of the oil quality and the oil level in the lubrication tank can be visually observed by using the utility model, which is convenient for charging, discharging, washing, replacing and controlling the liquid level. The utility model is convenient to install and debug. The utility model can reduce the situation that the ceramic stationary ring is broken because a bolt is unevenly pressurized.
Description
The utility model relates to a kind of sealing device for rotary shaft.
The vesselseals device is a kind of desirable seal that solves rotary seal, it is by at least one pair of end face perpendicular to spin axis, under the cooperation of the effect of the elastic force of hydrodynamic pressure and compensation mechanism and auxiliary seal, keep fitting and slide relative and constitute the device that prevents escape of liquid.The 212 type mechanical seals of producing as Wenzhou mechanical industry school trial (demonstration) plant in the prior art are to add gland on the stationary ring of silicon ceramic material, the periphery of gland is a lubricating oil tank, this lubricating oil tank is airtight, and whether the lubricant oil in the case needs to change or filling needs the lubricant oil case lid is opened just and can be known.
The purpose of this utility model is to provide a kind of situation that can observe lubricating oil tank easily, and the vesselseals device that can be lubricated the oil filling easily or change.
The technical solution of the utility model is: it comprises stationary ring, rotating ring and around the lubrication box of dynamic and static ring contacting point, the cavity bottom of lubrication box has lubricating oil pipeline, and this lubricating oil pipeline is connected with external level window.The bottom of described level window is provided with the oil discharge screw plug.The bottom of described lubrication box extends radially inwardly the formation pressure ring, and this pressure ring is pressed on the stationary ring.Be connected to a fixed with bolt between the extension part of the cooler bin of described extension part and below.
The utility model compared with prior art has following advantage:
(1). level window selects for use transparent material to make, and observes level window and can observe lubricating oil tank interior fluid position situation and oily situation intuitively, is convenient to timely filling, cleaning, replacing and liquid level control, needs only filling in level window during filling.
(2). level window below is provided with the oil discharge screw plug, turns on this bolt plug lubricant oil of can releasing.
(3). the bottom of lubrication box has pressure ring to be pressed on the stationary ring, in the lubrication box outside with bolt with cooler bin and lubrication box relative fixed, because the space in the lubrication box outside is very big,, can reduce owing to the crush situation of the stationary ring that the silicon pottery makes of the inhomogeneous pressurization of bolt so be convenient to the bolt adjustment.
The utility model will be further described below in conjunction with drawings and Examples:
Accompanying drawing is structure master's sectional view of the present utility model; Wherein:
［ 1 ］. water intake; ［ 2 ］. cooler bin; ［ 3 ］. pad; ［ 4 ］. bolt; ［ 5 ］. pad; ［ 6 ］. lubrication box; ［ 7 ］. stationary ring; ［ 8 ］. dust cover; ［ 9 ］. rotating ring; ［ 10 ］. retaining ring; ［ 11 ］. stirring shaft; ［ 12 ］. the lubrication box cavity; ［ 13 ］. level window; ［ 14 ］. the attaching nut; ［ 15 ］. the level window contiguous block; ［ 16 ］. the oil discharge screw plug; ［ 17 ］. lubricating oil pipeline; ［ 18 ］. water outlet; ［ 19 ］. pressure ring; ［ 20 ］. spring.
Referring to accompanying drawing, the utility model uses with sealing as the deep-etching still.It comprises stationary ring ［ 7 ］, rotating ring ［ 9 ］ and around the lubrication box ［ 6 ］ of dynamic and static ring contacting point, the cavity bottom of lubrication box ［ 6 ］ has lubricating oil pipeline ［ 17 ］, the bottom of described lubrication box ［ 6 ］ extends radially outwardly, described lubricating oil pipeline ［ 17 ］ promptly is located at this extension part, and this lubricating oil pipeline ［ 17 ］ is connected by attaching nut ［ 14 ］ with external level window ［ 13 ］.This level window ［ 13 ］ is made with transparent material, indicates scale and number above.This level window ［ 13 ］ is in identical horizontal position with lubrication box ［ 6 ］, and promptly the bottom of the bottom of lubrication box ［ 6 ］ and level window ［ 13 ］ is same horizontal position.The liquid level of level window ［ 13 ］ can demonstrate the liquid level of lubrication box ［ 6 ］ intuitively like this, is convenient to liquid level and observes, controls.The bottom of described level window ［ 13 ］ is provided with oil discharge screw plug ［ 16 ］.Turning on this bolt plug can bleed off the oil in the lubrication box ［ 6 ］.The bottom of described lubrication box ［ 6 ］ extends radially inwardly and forms pressure ring ［ 19 ］, and this pressure ring ［ 19 ］ is pressed on the stationary ring ［ 7 ］.Be provided with pad ［ 5 ］ between described pressure ring ［ 19 ］ and the stationary ring ［ 7 ］.Be provided with water intake ［ 1 ］ and water outlet ［ 18 ］ with a plurality of bolts ［ 4 ］ cooler bin ［ 2 ］ that is connected to a fixed between the extension part of the cooler bin of described extension part and below ［ 2 ］, cooling water constantly enters the temperature that can reduce seal arrangement in the cavity of cooler bin ［ 2 ］, prevents from high temperature to damage.The cooler bin ［ 2 ］ of described lubrication box ［ 6 ］ and below be can two parts, is the disassembly-type connection.Cooler bin ［ 2 ］ surface can Glassed Steel or lining teflon or make of other corrosion resisting alloy like this, reach corrosion-resistant desired structure, and lubrication box ［ 6 ］ but precision machining, reach the effect of sealing, application of slip glass deformation, low precision, the bad shortcoming of sealing effect when bringing when having avoided both for integral body.Retaining ring ［ 10 ］ is fixed on the stirring shaft ［ 11 ］, is provided with the spring ［ 20 ］ of compression between it and the rotating ring ［ 9 ］, and rotating ring ［ 9 ］ is closely contacted with sealing surface between the stationary ring ［ 7 ］, prevents to leak.
