Technical field
The present invention relates to seal technical field, specially a kind of back up seal part of the housing of fluid machinery.
Background technology
Mechanical sealing member belongs to one of Mechanical Fundamentals element accurate, that structure is complex, is various pump classes, reaction synthesis
The critical component of the equipment such as kettle, turbocompressor, submersible motor, mechanical sealing member belong to machinery accurate, that structure is complex
One of base components, it is the critical component of the equipment such as various pump classes, reaction synthesis reactor, turbocompressor, submersible motor.It is sealed
Performance and used life depends on many factors, such as precision of type selecting, machine, correctly installs and uses.Work is pressed in mechanical seal
Make condition and the difference of medium character, there is high temperature resistant, low temperature resistant mechanical seal, high pressure resistant, corrosion-resisting mechanical seal, resistance to particle is situated between
Mechanical seal of light hydrocarbon medium that matter mechanical seal and adaptation easily vaporize etc., different structure type should be chosen according to different use
The mechanical seal of formula and material.Mechanical sealing member is widely used in enterprise of all circles.
But most seal feature is all relatively simple in the market, it is also very inconvenient to use, due to
Traditional seal is typically made of acid bronze alloy or ferrous alloy, and seal surface slickness is good made of acid bronze alloy,
Coefficient of friction is low, but structural strength is relatively low, and service life is short, and cost is higher, and existing seal work one section when
Between after, its lubricant can not play lubrication well, main reason is that lubricant works as table than bearing body quick abrasion
After the lubricant attrition in face is fallen, enough lubrications can not be provided in follow-up a very long time, O-ring is easily caused and invades oil
Expansion or accelerated ageing, cause to seal premature failure.
The content of the invention
It is an object of the invention to provide a kind of back up seal part of the housing of fluid machinery, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the present invention provides following technical scheme：A kind of back up seal part of the housing of fluid machinery,
Including gland and shell, the case surface is provided with one end and is provided with adjustment layer, and the adjustment layer lower end is provided with chromium
Layer, the shell end surface are provided with neck, and the neck surrounding is provided with gland, and the gland outer wall surface is provided with close
Seal, the gland inwall are provided with locating piece, and the neck side is provided with locating slot, and the locating slot side is provided with through hole,
The through hole inner upper end is provided with counterbalance spring, and described counterbalance spring one end is provided with kollag, and the shell is another
End is provided with stationary ring.
Preferably, the shell snaps connection with gland.
Preferably, kollag is kollag made of bar-shaped graphite or molybdenum disulfide.
Preferably, 0.1-0.5mm gaps are left between kollag and through hole.
Preferably, shell is fixedly connected with chromium layer.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is inlaid with kollag in through hole, has self-lubricating property by the kollag of setting.In addition,
Kollag is propped up by counterbalance spring, because counterbalance spring has certain decrement, in use, kollag
It can outwards be extruded by counterbalance spring with abrasion, compensate wear extent automatically, remain good lubricant effect, simultaneously because
Kollag is located at one end of counterbalance spring, therefore can play more preferable lubricant effect, avoid causing O-ring invade oil expansion or
Accelerated ageing, cause to seal premature failure, there are good market prospects.
2nd, the present invention passes through the chromium layer of setting, it is possible to increase the overall intensity of seal, toughness, hardness, it is wear-resisting and
Rust-resisting property, while can also reach the protection to environment, the service life of seal is improved, it also avoid the waste of resource.
3rd, the present invention is by the locating slot of setting, and when gland is arranged on shell, locating piece can be stuck in locating slot, energy
Enough precisions for improving installation, installation situation devious is prevented, ensure that the using effect in seal later stage, be adapted to big
Batch production uses.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：A kind of back up seal part of the housing of fluid machinery, bag
Gland 1 and shell 4 are included, the surface of shell 4 is provided with one end and is provided with adjustment layer 10, and the lower end of adjustment layer 10 is provided with chromium
Element layer 9, the end surface of shell 4 are provided with neck 3, and the surrounding of neck 3 is provided with gland 1, the outer wall table of gland 1
Face is provided with sealing ring 2, and the inwall of gland 1 is provided with locating piece 12, and the side of neck 3 is provided with locating slot 8, the positioning
The side of groove 8 is provided with through hole 7, and the inner upper end of through hole 7 is provided with counterbalance spring 11, and described one end of counterbalance spring 11 is provided with solid
Body lubricant 5, the other end of shell 4 are provided with stationary ring 6.When gland 1 is arranged on shell 4, locating piece 12 can be stuck in fixed
In the groove 8 of position, it is possible to increase the precision of installation, prevent installation situation devious, ensure that the use in seal later stage
Effect, it is adapted to produce use in enormous quantities.
The shell 4 snaps connection with gland 1；Kollag 5 is solid made of bar-shaped graphite or molybdenum disulfide
Lubricant；0.1-0.5mm gaps are left between kollag 5 and through hole 7；Shell 4 is fixedly connected with chromium layer 9.
Operation principle：When gland 1 is arranged on shell 4, locating piece 12 can be stuck in locating slot 8, it is possible to increase installation
