Abstract
The utility model relates to a mechanical sealing device, in particular to a cartridge type mechanical sealing device. A static ring, a movable ring, a spring and a static ring pressing cover are arranged on a shaft sleeve, the movable ring is in tight contact with the static ring, the shaft sleeve is in clearance fit with the movable ring through a rubber L-shaped pad, the static ring is connected with a static ring seat which is connected with the static ring pressing cover through a drive pin, an O-shaped sealing ring and the spring are arranged between the static ring seat and the static ring pressing cover, and the spring is arranged in a spring groove of the static ring pressing cover. The mechanical sealing device is compact in structure, convenient to disassemble, repair and maintain, and high in installation accuracy.
Description
Technical field
The utility model relates to seal arrangement, relates in particular to a kind of integrated mechanical sealing device.
Background technique
But the existing play unit loading type of order slag stock pump mechanical sealing element, work a period of time, because the wearing and tearing of the pump housing cause pump shaft cover generation axial displacement, Sealing is proper functioning also, but has realized play design of rubber seal function.But because dismounting, maintenance, maintenance inconvenience and installation precision are not high, thereby broken, must remove a plurality of links and could replace this part because of an easily damaged parts.So not only time-consuming, effort also influence working efficiency.
Summary of the invention
The utility model provides a kind of integrated mechanical sealing device at above deficiency, makes it solve existing like product dismounting, maintenance, maintenance inconvenience, the technical problem that installation precision is not high.
The technological scheme that the utility model adopted is:
A kind of mechanical seal device, axle sleeve is provided with stationary ring, rotating ring, spring, seal end plate, rotating ring closely contacts with stationary ring, axle sleeve is by rubber L pad and rotating ring interference fit, stationary ring connects stationary seat, stationary seat connects seal end plate by driving pin, is provided with O RunddichtringO and spring between stationary seat and the seal end plate, and spring places in the spring groove of seal end plate.Stationary seat is connected with seal end plate, and seal end plate is fixedlyed connected with the pump housing, i.e. seal end plate restriction stationary ring rotates, and when pump shaft rotated, pump shaft drove rotating ring and rotates, and rotating ring and stationary ring are realized sealing for the friction rotation.
Described seal end plate is provided with water outlet.
Be provided with the O RunddichtringO between described axle sleeve and pump shaft, make to produce sealing between axle sleeve and the pump shaft, prevent liquid or gas leakage.
Be provided with limited ring between described seal end plate and the positioning ring, this limited ring plays position-limiting action to seal end plate.
The utility model beneficial effect is:
Compact structure, dismounting, maintenance, maintenance are comparatively convenient, and installation precision is higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure 1, axle sleeve, 2, stationary ring, 3, rotating ring, 4, spring, 5, seal end plate, 6, stationary seat, 7, the O RunddichtringO, 8, the pump housing, 9, positioning ring, 10, limited ring.
Embodiment:
As shown in drawings, a kind of mechanical seal device, axle sleeve 1 is provided with stationary ring 2, rotating ring 3, spring 4, seal end plate 5, rotating ring 3 closely contacts with stationary ring 1, axle sleeve 1 is by rubber L pad and rotating ring 3 interference fit, and stationary ring 2 connects stationary seat 6, and stationary seat 6 connects seal end plate 5 by driving pin, be provided with O RunddichtringO 7 and spring 4 between stationary seat 6 and the seal end plate 5, spring 4 places in the spring groove of seal end plate 5.Stationary seat 6 is connected with seal end plate 5, and seal end plate 5 is fixedlyed connected with the pump housing 8, and promptly seal end plate 5 restriction stationary rings rotate, and when pump shaft rotated, pump shaft drove rotating ring 3 and rotates, and rotating ring 3 is realized sealing with stationary ring 2 for the friction rotation.
Described seal end plate 5 is provided with water outlet.
Be provided with O RunddichtringO 7 between described axle sleeve 1 and pump shaft, make to produce sealing between axle sleeve 1 and the pump shaft, prevent liquid or gas leakage.
