Abstract
This utility model relates to a boiler slag pump mechanical sealing device in the mechanical sealing device field, designed to solve the problem that similar mechanical sealing elements change vulnerable parts and the maintenance work amount is relatively large. This device comprises a pump shaft, a shaft sleeve, a moving ring part and a stationary ring part, wherein the moving ring part comprises a moving ring and a moving ring sealing gasket, the stationary ring part comprises a stationary ring, a stationary ring seal ring, a throw-out collar, a spring and a spring base, characterized in that the moving ring employs a pull ring of the axle sleeve as a gripper ring, the moving ring sealing gasket employing a L-shaped rubber gasket is pressed into the axial sleeve, the stationary ring is connected with the spring base via driving pin locating, the stationary ring part is permanently connected with a gland via screws and integrated with the gland, the stationary ring part and the moving ring part are respectively sleeved with the axle sleeve and is plugged into the axial sleeve guiding slot via a restriction plate, the axle sleeve and a throat ring are sleeved into the pump shaft and screwed connected with the fixed pump body, and an inner flushing hole is connected with an inner flushing device. This utility model is applicable to cleaning furnace slag in steel plant and sealing of boiler slag devices in heat power plant.
Description
Technical field
The utility model relates to the mechanical sealing element field, is applicable to the cleaning of Iron And Steel Plant slags, the slag tap sealing of equipment of heat power plant boiler.
Background technique
At present, the boiler pump seal of slagging tap generally adopts packing seal, owes because of working environment, causes service life of equipment to become short.In recent years along with the raising of country to environmental requirement, the attention of enterprise's environmental pollution, the boiler pump seal of slagging tap substitutes packing seal with mechanical seal gradually.But since boiler to go out pulp pump applying working condition condition poor, the common mechanical seal durability also has only three months, and change easily damaged parts, maintenance load is bigger.
Summary of the invention
The purpose of this utility model is the problem at above-mentioned existence, provides a kind of boiler pump mechanical sealing device of slagging tap to related domain, and it is poor to make it can solve the applying working condition condition, and working life is shorter, the relative cost technical problems of high.The purpose of this utility model is to adopt following technological scheme to realize.
A kind of boiler pump mechanical sealing device of slagging tap, this device comprise pump shaft, axle sleeve, rotating ring part, stationary ring part.The rotating ring part is made up of rotating ring 4, rotating ring sealing gasket 3, it is bearing ring that rotating ring is stretched circle 2.1 with the edge of axle sleeve 2, rotating ring 4 is pressed in the axle sleeve by rotating ring sealing gasket 3, and the rotating ring sealing gasket adopts L shaped rubber pad, the damage that the pump shaft swing causes when having solved traditional O-ring seals sealing owing to work.The stationary ring part is made up of stationary ring 5, stationary ring seal ring 6, throw-out collar 7, spring 8 and spring seat 9, and the stationary ring seal ring seals.Stationary ring is prevented because the relative friction of rotating ring causes the rotation of stationary ring by driving pin 15 spring seat that is located by connecting.Stationary ring partly passes through screw 14 fixedly connected glands 13, and fuses with gland.Stationary ring part, rotating ring part are inserted in axle sleeve respectively, and insert the guiding groove of axle sleeves by limiting board 16, the boiler pump mechanical sealing device of slagging tap.Axle sleeve, restrictor ring 1 are inserted in pump shaft 18, and bolt 11 is fastened on the pump housing 10, and by 12 sealings of 0 shape B circle.Restrictor ring shown in Figure 1 is made with teflon, and wear resistance is good, and its effect is the gap of reducing between the pump housing and the axle sleeve, makes the pressure difference between Seal cage and the pump chamber.To prevent that the assorted slag in the pump chamber from entering Seal cage too much.Rinsing unit 20 in Seal cage pressure is connected by interior flushing hole 19, the drafting of Rinsing unit in omitting among the figure.Axle sleeve is axle sleeve both ends of the surface extruding location at the pump internal fixation, the leakage between 0 shape A circle, 17 sealing pump shafts and the axle sleeve.
The utility model adopts the mechanical seal integrally assembled type, has overcome the shortcoming of conventional seals part installation and maintenance difficulties.Rinsing unit combines with restrictor ring in increasing, and guarantees Seal cage pressure greater than pump chamber pressure, stops the assorted slag in the pump chamber to enter Seal cage, and mechanical seal device is always worked in the clear water of relative clean.The utility model belongs to integrally assembled type mechanical seal, and it is relatively poor therefore to have solved the applying working condition condition, and working life is shorter, the relative cost technical problems of high.Can substitute the slag cleaning of existing Iron And Steel Plant, the slag tap Sealing of equipment of heat power plant boiler.

Embodiment
Mechanical seal device goes out pulp pump with boiler and is connected comparatively easy, the integrally assembled type mechanical seal device need only be inserted in the pump shaft, restrictor ring 1 penetrates gland 13 with bolt 11 again near the pump shaft 18 and the pump housing 10, and the internal thread in the outside thread of bolt and pump housing hole screws and gets final product.
