Description
Technical field
The utility model belongs to anticorrosion antiwear pump field, specifically, relates to a kind of mechanical seal structure.
Background technique
In the running shaft end that a few thing rotating speed is very high, the mode of mechanical seal is used to get more and more.Mechanical seal is compared with traditional soft packing seal, and it is lightweight, and shared space is less, and will grow working life a lot; Mechanical seal is compared with traditional labyrinth seal, and its size is compacter, easy for installation, reliability is high, can be good at the seal request meeting high-speed drive component.
At present, mostly the structure that mechanical seal adopts is that rotating ring and stationary ring match, but existing mechanical sealing element exists obvious defect.One is the end contact imprecision of rotating ring and stationary ring, easily causes fuel oil or lubrication leakage.Two is situations that rotating ring and stationary ring can go out heating after working long hours, and cause damage, especially stationary ring, such sealing effect will reduce greatly.
So, the previous problem demanding prompt solution of order is the mechanical seal structure that innovation and creation are applicable to anticorrosion antiwear pump, reasonable in design, environmental protection is reliable, structure is simple, and low cost of manufacture, has good seal action simultaneously, avoid pump housing work or idle time have foreign material or greasy dirt to enter, have influence on the effect of sealing; In addition, can make after dynamic and static ring surface of contact is worn, can promote stationary ring and move vertically, remain and fit tightly, and cooling cover add heat diffusion area, be conducive to heat radiation, meanwhile, the use of oil sealing strengthens sealing effect greatly.
Model utility content
The technical problems to be solved in the utility model overcomes above-mentioned defect, a kind of mechanical seal structure is provided, reasonable in design, environmental protection is reliable, structure is simple, and low cost of manufacture, has good seal action simultaneously, avoid pump housing work or idle time have foreign material or greasy dirt to enter, have influence on the effect of sealing; In addition, can make after dynamic and static ring surface of contact is worn, stationary ring can be promoted and move vertically, remain and fit tightly, and cooling cover adds heat diffusion area, be conducive to heat radiation, simultaneously, the use of oil sealing strengthens sealing effect greatly, practical, is suitable for promoting.
For solving the problem, the technological scheme that the utility model adopts is:
A kind of mechanical seal structure, corresponding with the pump housing, it is characterized in that: comprise the axle sleeve be connected on the pump housing, axle sleeve is provided with rotating ring and static components; Described static components comprises the stationary seat be socketed on axle sleeve, and by stationary ring that stationary seat is installed; Described axle sleeve is provided with cooling cover structure; Pad is provided with between described cooling cover structure and static components.
As a kind of technological scheme of optimization, described cooling cover structure comprises cooling cover, is provided with spring assembly between cooling cover and axle sleeve; One end of described cooling cover is connected with axle sleeve by cooling cover gland.
As a kind of technological scheme of optimization, described spring assembly comprises the spring be arranged between cooling cover and axle sleeve, and is provided with spring seat between cooling cover and stationary seat.
As a kind of technological scheme of optimization, one end of described pad is arranged between stationary ring and spring seat, and the other end is fixed between the cooling cover pump housing.
As a kind of technological scheme of optimization, described cooling cover, between axle sleeve and cooling cover gland, be provided with oil sealing.
Owing to have employed technique scheme, compared with prior art, the utility model is reasonable in design, environmental protection is reliable, structure is simple, low cost of manufacture, the pad be arranged between stationary ring and cooling cover can play good seal action, avoid pump housing work or idle time have foreign material or greasy dirt to enter, have influence on the effect of sealing, and the utility model spring and spring seat coordinate and can make after dynamic and static ring surface of contact is worn, promote stationary ring to move vertically, remain and fit tightly, simultaneously, cooling cover adds heat diffusion area, be conducive to heat radiation, simultaneously, the use of oil sealing strengthens sealing effect greatly, practical, be suitable for promoting.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
Embodiment
Embodiment:
As shown in Figure 1, a kind of mechanical seal structure, corresponding with the pump housing, corresponding with the high-speed rotary part on the pump housing specifically.Mechanical seal structure comprises the axle sleeve 10 be connected on the pump housing, axle sleeve 10 is provided with rotating ring 1 and static components.Described static components comprises the stationary seat 2 be socketed on axle sleeve 10, and by stationary ring 3 that stationary seat 2 is installed.Described axle sleeve 10 is provided with cooling cover structure.Pad 4 is provided with between described cooling cover structure and static components.
Described cooling cover structure comprises cooling cover 5, is provided with spring assembly between cooling cover 5 and axle sleeve 10.One end of described cooling cover 5 is connected with axle sleeve 10 by cooling cover gland 8.
Described spring assembly comprises the spring 7 be arranged between cooling cover and axle sleeve, and is provided with spring seat 6 between cooling cover 5 and stationary seat.
One end of described pad 4 is arranged between stationary ring 3 and spring seat 6, and the other end is fixed between cooling cover and the pump housing.Pad can play good seal action, avoid pump housing work or idle time have foreign material or greasy dirt to enter, have influence on the effect of sealing.
Described cooling cover, between axle sleeve and cooling cover gland, be provided with oil sealing 9.The effect of oil sealing 9 avoids allowing the seepages such as lubricant oil, and impact normally works.
The utility model is reasonable in design, environmental protection is reliable, structure is simple, low cost of manufacture, the pad be arranged between stationary ring and cooling cover can play good seal action, avoid pump housing work or idle time have foreign material or greasy dirt to enter, have influence on the effect of sealing, and the utility model spring and spring seat coordinate and can make after dynamic and static ring surface of contact is worn, promote stationary ring to move vertically, remain and fit tightly, simultaneously, cooling cover adds heat diffusion area, be conducive to heat radiation, simultaneously, the use of oil sealing strengthens sealing effect greatly, practical, be suitable for promoting.
