Abstract
The utility model relates to a mechanical sealing device under a grain oil condition. The mechanical sealing device under the grain oil condition comprises static ring assemblies, a movable ring and a movable ring base, wherein the movable ring is embedded in a step surface of the movable ring base. The mechanical sealing device under the grain oil condition further comprises a spring and a gland, wherein the number of the spring is one, the spring is installed on step surfaces of the static ring assemblies through a spring washer, and a static O-shaped ring is arranged between the static ring assemblies. According to the mechanical sealing device under the grain oil condition, a plurality of small springs are changed into the single large spring, the interval between circles of the single large spring is large, elastic force is high, the spring is not blocked by grease easily, and the problem that the spring is often blocked by grease under the grain oil condition is resolved.
Description
Technical field
The utility model relates to a kind of mechanical seal device, relates in particular to a kind of for the mechanical seal device under the grain and oil operating mode.
Background technique
At present, what in mechanical sealed driving device, use is many springs, little spring sealing, but also improper in the operating mode of grain and oil; little spring often can be stopped up by grease, makes the spring lost its bounce, and seal ring loses compensation; cause leaking, reduced sealing reliability and sealing life.
The model utility content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of simple installation is provided, improve sealing life for the mechanical seal device under the grain and oil operating mode.
The utility model technical solution problem adopts following technological scheme:
A kind of for the mechanical seal device under the grain and oil operating mode, comprise static components, rotating ring, rotating seat, described rotating ring is installed in the step surface of rotating seat, also comprise spring and gland, described spring is single spring, it is arranged on by compression spring on the step surface of static components, is provided with stationary ring O type circle between described static components.
As preferably, be provided with groove in described gland, place gland O type circle in groove, described gland links together by hexagon socket cap head screw and gland cover plate.
As preferably, described rotating seat is provided with radial groove towards rotary component one end, its built-in rotating seat O type circle, and the step surface place that described rotating seat is connected with rotating ring is provided with rotating seat O type circle.
Compared with prior art, the beneficial effects of the utility model are: the utility model is by changing to single big spring to a plurality of little springs, gap between the circle of single big spring and circle is large, elastic force is large, be not easy to be stopped up by grease, solved the problem of often being stopped up by grease at grain and oil operating mode medi-spring.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation for the mechanical seal device under the grain and oil operating mode of the utility model.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
