Abstract
The invention discloses a high-pressure metering pump plunger sealing filler which comprises an opening type rectangular sealing ring, a V-shaped sealing ring and a jacket aluminum triangular heat radiating sealing ring. In the invention, because different forms of sealing rings with respective characteristics are adopted and combined into a whole, and the sealing rings are made of self-lubricating filling polytetrafluoroethylene, the combination of the three sealing materials ensures that the filler has better self-lubricating property, sealing property and heat radiating property, replaces an original spheroidal graphite cast iron filler, saves an oil injector and cooling water, realizes oil-free lubrication and has good sealing property and long service life.
Description
Technical field the present invention relates to chemical machinery, directly relates to metering pump plunger Oil Free Packing Seals.
Most spheroidal graphite iron ring, nylon ring or the rubber seal of adopting of the metering pump plunger packing that background technique is used at present, wear-resisting property is poor, needs continuous oil injecting lubricating, also needs cooling water to reduce temperature.Sealing effect is poor, and working life is short, and amount of maintenance is big.Study a kind of oil-free lubrication and high voltage bearing stuffing box packing is very necessary.
Summary of the invention purpose of the present invention just provides a kind of PASP solution metering pump plunger oil-free lubrication filler, replaces original spheroidal graphite cast iron filler, has saved oil gun and cooling water, has realized oil-free lubrication, good seal performance, long service life.
The object of the present invention is achieved like this, and PASP solution metering pump plunger oil-free lubrication filler is made up of open type rectangular seal ring, V-shaped ring, overcoat aluminium triangle heat radiation seal ring.
As further scheme of the present invention, the section of described open type rectangular seal ring (1) is a rectangle, dress stretched spring in the semicircle groove of periphery turning, material selection selflubricating filled polytetrafluoroethylene
As further again scheme of the present invention, described V-shaped ring (2) is the self sealing seal ring that a parafacies interworking is closed, material selection selflubricating filled polytetrafluoroethylene
As further again scheme of the present invention, described overcoat aluminium triangle heat radiation seal ring (3) is that a parafacies interworking is closed V-shaped ring, and wherein outer shroud is the aluminium ring, and interior ring is the selflubricating filled polytetrafluoroethylene.
Because the present invention adopts multi-form seal ring, differ from one another, be combined into one, and material adopts the selflubricating filled polytetrafluoroethylene, so the combination of three kinds of seal rings makes this filler have better self lubricity, sealing, thermal diffusivity, has replaced original spheroidal graphite cast iron filler, oil gun and cooling water have been saved, realized oil-free lubrication, good seal performance, long service life.
Appended drawings is the structural representation of PASP solution metering pump plunger oil-free lubrication filler of the present invention.
The embodiment accompanying drawing shows the structure of PASP solution metering pump plunger oil-free lubrication filler of the present invention, and the overcoat aluminium triangle of packing into successively in former stuffing box 2 heat radiation seal ring 3 guarantees that plunger does not sink; Spring 4, rectangular aperture seal ring 5 at the tight lock plug of effect under shed ring of spring force, stop liquid to leak along plunger; V-seal ring 2 is a secondary seal ring that cooperates because of it, under the pressure ring effect, and the auto lock plunger, secondary stops leaked liquid; Triangle seal ring 8 is big because of itself and plunger area of contact, has effectively stoped preceding two groups of a small amount of low pressure liquids of revealing, and aluminum outer shroud 7 has good thermal diffusivity, because of the timely unofficial biography of fricative heat.The seal ring that contacts with plunger is all selected the filled polytetrafluoroethylene with good selflubricating for use, has realized oil-free lubrication, has omitted complicated oiling device.After seal ring installs successively, assembly parts is compressed with pressure ring 9 and gland 10.
