Abstract

Hinder husky seal assembly is the sealed and oil recovery sealing technique of high -pressure reciprocating pump, and it has overcome other technological shortcomings, and it is by sealed main part, sealing washer, hinder husky ring, the guide ring assembles and forms, and sealed main part is installed at sealed letter internally to the cover forms the no clearance fit who hinders husky ring and plunger, then is installing in proper order in one side of sealing washer and hindering husky ring sum guide ring on the plunger.

Description

Hinder husky black box

Technical field:

The utility model relates to high pressure reciprocating pump sealing and oil recovery sealing technique, especially hinders husky black box.

Background technique:

At present, during known high pressure reciprocating pump return water, the part and the seal life-span that there is motion are short, the phenomenon that cost is high, the basic reason forming this phenomenon is, considerable impurity is had in sewage, the composition 60 percent of these impurity is various hard stone grains, under the compressing of high hydraulic pressure, these hard stone grains stick to the surface of sealing material, and the movement parts contacted with it just suffers breakage, and the breakage of movement parts exacerbates again the more holocaust power to sealing material, finally causing seal failure, also there is same state in oil pumping polish rod sealing.

Summary of the invention:

It is simple that the purpose of this utility model is to provide a kind of structure, the husky black box of resistance of long service life, which overcome the shortcoming of other technology, the purpose of this utility model realizes like this, it is assembled by sealed body, seal ring, the husky ring of resistance, guide ring, and sealed body is arranged in sealed letter body, and is enclosed within plunger, form the blind-mate of the husky ring of resistance and plunger, then in the side of seal ring order, the husky ring of resistance and guide ring are installed.

The husky ring of described resistance, it has an opening around ring.

Application process of the present utility model is, when plunger moves reciprocatingly, hinder husky ring under the effect of seal ring, adhere to plunger surface tightly, make plunger surface and hinder between husky ring internal diameter to form blind-mate, seal ring forms elastic compensating to the husky ring of resistance and reaches the husky object of resistance, block minitype particle and enter sealant surface, solve the breakoff phenomenon of above-mentioned generation, great effect is created to the reliability of high pressure sealing under guarantee motion state, extend the working life two to three times of related accessory, reach energy-saving and cost-reducing remarkable result; Increase the benefit 50%, reduce the labor intensity of operator.

Accompanying drawing illustrates:

Fig. 1 is the structural representation hindering husky black box, in figure 1, sealed body 2, seal ring 3, hinders husky ring 4, guide ring 5, plunger.

Fig. 2 is the structural representation hindering husky ring, in figure 3, hinders husky ring.

Embodiment:

Embodiment 1, the utility model be by sealed body 1, seal ring 2, hinder husky ring 3, guide ring 4, plunger 5 are assembled, sealed body 1 is arranged in sealed letter body, and be enclosed within plunger 5, form the husky ring 3 of resistance and the blind-mate of plunger 5, then in the side of seal ring 2 order, the husky ring 3 of resistance and guide ring 4 are installed.

Embodiment 2, the husky ring 3 of described resistance, it has an opening around ring.
