Description

Unit loading type calcium plaster excavationg pump rotary shaft sealing
Technical field
The utility model relates to a kind of mechanical rotation shaft sealer, particularly relates to a kind of unit loading type calcium plaster excavationg pump rotary shaft sealing.
Background technique
Up to now, mechanical seal device miscellaneous is arranged on the market, to be applicable to various working environment.But, existing seal arrangement and product, still can satisfy the demand to general operating conditions, and meet bad working environment, as medium be that fine particle is corrosive, under the high-temperature and high-pressure conditions, sealed product commonly used just is difficult to be competent at, its sealing effect is relatively poor, working life is short, and defectives such as equipment operation poor stability are completely exposed.Therefore, the application area of seal arrangement commonly used is restricted.
Summary of the invention
The purpose of this utility model, exactly in order to overcome the defective of prior art, a kind of demand that can satisfy particular job environment is provided, adapts to fine particle medium, corrosion-resistant, rub resistance, good seal performance, long service life, the Security of raising equipment operation, be easy to form the integrated form calcium plaster excavationg pump rotary shaft sealing of industrialized mass.
To achieve these goals, the technological scheme of the related unit loading type calcium plaster excavationg pump rotary shaft sealing of the utility model is such: it is made of machine end-blocking lid, machine big envelope, stationary ring, rotating ring, rotating seat and spring.It is characterized in that machine end-blocking lid is stepped, stationary ring be installed in end cap lower step shape the space in, be provided with in the stepped space of the groove of stationary ring and end cap an O type circle and with stationary ring, end cap interference fit, stationary ring and end cap are fixed by locating steel pin; Rotating ring is placed in the stepped space, rotating seat the right, be provided with therebetween an O type circle and with rotating ring, rotating seat interference fit, rotating ring groove and rotating seat are located by the location steel pin, the right side of rotating ring contacts with the left side of stationary ring; Rotating seat left side end face is equipped with spring, and the bottom end of rotating seat is close in the spring outer, and the spring lower end is embedded in the machine big envelope groove, is provided with an O type circle between machine big envelope and the rotating seat; Be connected by the exoskeletal oil sealing of V-type between rotating ring and the machine big envelope; Positioning block links to each other with end cap by bolt, and outside framework oil seal is equipped with in its continuous corner; Machine big envelope and pump shaft cover are connected and fixed by fastening screw; The cooling water nozzle penetrates straight-through Seal cage from the top of end cap, and cooling water enters from water nozzle, under the state of the flushing of cooling water, guarantees that stationary ring and rotating ring have a good working environment, has protected quiet, rotating ring not to be subjected to frictionally damage; Because V-shaped mouthful of the exoskeletal oil sealing of V-type under cooling water impacts, outwards expands the V-type mouth, stops cooling water to enter the pump housing, plays good sealing effect; O type circle is equipped with at step groove place, the end cap left side, seals.Rotating seat cooperates spring, gives reasonable pressure of rotating ring, makes quiet, even, the good sealing effect of rotating ring cooperation pressure, and the life-span is long.
The unit loading type calcium plaster excavationg pump rotary shaft sealing that the utility model is related is characterized in that rotating seat is butterfly and the exterior edge face is streamline.
The unit loading type calcium plaster excavationg pump rotary shaft sealing that the utility model is related is characterized in that spring is the butterfly spring.
The unit loading type calcium plaster excavationg pump rotary shaft sealing that the utility model is alleged has reasonable in design, process specification, is easy to make, and non-environmental-pollution is suitable for characteristics such as industrialized mass; Have corrosion-resistant, wear-resistant, good sealing effect, long service life, guarantee operational outfit safely, be suitable for the advantages such as use of particular surroundings.The utility model utilizes the structural design of butterfly rotating seat and butterfly spring, rationally by the pressure of medium, promotes rotating seat equably to the axial displacement of stationary ring end, has guaranteed sealing effect better; It is extremely tired for a long time and reduce the effect of pressure to slow down simultaneously the butterfly spring again, has effectively prolonged the working life of butterfly spring; On the other hand, the Seal cage internal pressure is given butterfly spring aux. pressure, and the butterfly spring is increased the service life, and gives the rotating seat uniform pressure all the time, guarantees that the pressure balance of rotating ring and stationary ring is even, effectively stops the fine particle medium by quiet, rotating ring end face.The utility model can be widely used in fields such as metallurgy, electric power, chemical industry, mine, is particularly useful on the equipment of power plant desulfurization and fine particle medium.
