Fig. 1 is the structural representation of mechanical seal in prior art;
Fig. 2 is the structural representation of integrated mechanical sealing in this utility model.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in detail.
Embodiment 1:
Present embodiments provide for a kind of integrated mechanical sealing, as shown in Fig. 2 this mechanical sealing static ring 1, rotating ring 2, tool
It is made up of the gland 5 of water inlet 501 and outlet 502, bearing 7 and bearing gland 8, wherein stationary ring 1, rotating ring 2, bearing 7 and
Bearing gland 8 is sequentially sleeved on mechanical axis 4, and stationary ring 1 is fixed with the external flanges 3 being enclosed within mechanical axis 4, and therebetween
Sealed by pad 10, between rotating ring 2 and stationary ring 1, face contacts, sealed by oil sealing 9 between bearing 7 and rotating ring 2, bearing 7 and machine
Pass through o type circle 11 sealing between tool axle 4 to fix, gland 5 is enclosed within stationary ring 1 and rotating ring 2 periphery, and gland 5 and stationary ring 1 and rotating ring
Form seal cavity 6 between 2, it is fixing to pass through hexagon socket cap head screw 12 between one end of gland 5 and flange 3, with stationary ring 1 it
Between sealed by pad 10, it is fixing that the other end of gland 5 and bearing gland 8 pass through hexagon socket cap head screw 12, and passes through o type
Circle 11 sealing.
Above-mentioned rotating ring 2 is main to be made up of corrugated tube 202, drag ring 201 and point half snap ring 203, therein point of half snap ring 203
By hexagon socket cap head screw 12, corrugated tube 202 is pressed abd fixed on mechanical axis 4, one end intercalation of drag ring 201 is in ripple
In stricture of vagina pipe 202, between the other end and stationary ring 1, face contacts, and this contact surface is the flour milling between rotating ring 2 and stationary ring 1, in corrugated tube
202 peripheries are also cased with the elastomeric element 204 being made up of spring 2041 and spring base 2042, and spring base 2042 is the cup of one end open
Body structure, one end of spring 2041 is located in spring base 2042, and the other end reaches outside spring base 2042, in order to prevent spring
2041 are contaminated by dust, and stretch out in spring 2041 and are additionally provided with dust cover between one end of spring base 2042 and point half snap ring 203
205, due to the elastic force effect of spring 2041, spring base 2042 is compacted to be stuck between spring 2041 and corrugated tube 202, dust cover
205 are stuck between spring 2041 and point half snap ring 203;Corrugated tube 202 has certain elasticity in itself, can be in above-mentioned flour milling
Long-time rub after ensure in sealing contact between stationary ring 1 and drag ring 201, add the effect of spring 2041 so that stationary ring 1 with
In sealing contact even closer between drag ring 201, sealing effectiveness is more preferable.
The operation principle of this mechanical seal is as follows:
Before mechanical axis 4 rotates, cooling water is injected into seal cavity 6 by water inlet 501, then rotates mechanical axis 4,
The rotation of mechanical axis 4 drives rotating ring 2 and bearing 7 to rotate together, drag ring while rotating, in stationary ring 1 and rotating ring 2
All surround cooling water around flour milling between 201, and this cooling water can be flowed out by outlet 502 and form circulating cooling
So that the temperature on flour milling will not raise, after mechanical axis 4 rotates a period of time, mechanical axis 4 left end has liquid through stationary ring to water
Gap between 1 and mechanical axis 4 reaches around flour milling, because the temperature difference between flour milling temperature now and liquid is not
Very big, thus flour milling temperature will not the rapid drawdown because of the arrival of liquid, effectively prevent the cracking of flour milling, prevent liquid from letting out through flour milling
Leakage, this is first seal point;Due to all there being pad 10 to seal between flange 3 and stationary ring 1 and stationary ring 1 and gland 5, so liquid
Body will not be through the clearance leakage between flange 3 and stationary ring 1 and stationary ring 1 and gland 5, and this is second seal point;In addition, rotating ring
Corrugated tube 202 in 2 is fixed on outside mechanical axis 4 by point half snap ring 203 clamping, so between corrugated tube 202 and mechanical axis 4
It is sealing, prevent liquid through the clearance leakage between corrugated tube 202 and mechanical axis 4, this is the 3rd seal point;Above three
The sealing function of aspect makes the sealing effectiveness of this mechanical seal reach most preferably.Pass through o type circle 11 between bearing 7 and mechanical axis 4
Sealing, can prevent the outside moisture on mechanical axis 4 right side from entering mechanical seal through the gap between bearing 7 and mechanical axis 4, and o type
Circle 11 can carry dynamic bearing 7 to follow mechanical axis 7 and rotate together.
Embodiment 2:
Present embodiment is the improvement further of embodiment 1, mainly thes improvement is that: in embodiment 1, in order to
It is easy to assemble, typically can will leave certain gap between bearing 7 and mechanical axis 4, so when mechanical seal is in outdoor application,
The gap that rainy day rainwater is easily accessible between bearing 7 and mechanical axis 4 leads to bearing 7 to get rusty, bearing after getting rusty 7 and machinery
Frictional force between axle 4 is larger, is easily caused when o type circle 11 rotates with mechanical axis 4 and dynamic bearing 7 cannot be carried to rotate,
And o type circle 11 can be led to be damaged by friction, the integral sealing effect of impact mechanical seal;And the mechanical seal in present embodiment
It is additionally provided with pin 13, in point half snap ring 203, the other end blocks bearing 7 for one end intercalation of this pin 13, so, when point half
When snap ring 203 rotates with mechanical axis 4, pin 13 also concomitant rotation, and then carry dynamic bearing 7 also and then to rotate, it is to avoid o type
Relative displacement between circle 11 and bearing 7, effectively prevents o type circle 11 to be worn, lifts the integral sealing effect of this mechanical seal.
Above-mentioned embodiment is only that technology design of the present utility model and feature are described, its object is to allow and is familiar with this skill
The people of art will appreciate that content of the present utility model and implements according to this, can not limit protection domain of the present utility model with this.
All equivalent transformations being done according to this utility model spirit or modification, all should cover protection domain of the present utility model it
