Specific embodiment

Below with reference to accompanying drawing, specific embodiment of the utility model is described in detail.

Existing ESP producing line for aforementioned proposition pushes away the useless bearing damage measuring on roller, body of roll deformation, leak and nothing The problems such as method meets generation needs, the utility model proposes a kind of ESP producing line pushes away useless measurement roller, empty using compression inside the body of roll Air cooling；Roll surface is provided with helical groove；Bearing block increases metal on the basis of being sealed in original outside framework oil seal and folds ring sealing group, this Sample is designed to the needs solving to produce now.

Measure the structure of roller in order to illustrate that the ESP producing line that this utility model provides pushes away to give up, Fig. 1 to Fig. 3 is respectively from different angles The structure that the ESP producing line that degree provides to this utility model pushes away useless measurement roller has carried out exemplary sign.Specifically, Fig. 1 shows Useless measurement roll structure is pushed away according to the ESP producing line of this utility model embodiment；Fig. 2 shows according to this utility model embodiment ESP producing line pushes away useless measurement roller side-looking structure；Fig. 3 shows that pushing away useless measurement roller according to the ESP producing line of this utility model embodiment cuts Face structure.

As Fig. 1 to Fig. 3 is jointly shown, the ESP producing line that this utility model provides pushes away useless measurement roller and includes the body of roll 10, is arranged on The bearing block 4 of the roll neck 17 at the body of roll 10 two ends, the bearing 6 being set on roll neck 17 and fixing bearing 6, wherein, in the body of roll 10 Portion is provided with two passages, respectively passage 14 and passage 14 ', and the compressed air within the cooling body of roll 10 passes through ventilation Hole 14 and passage 14 ' enter inside the body of roll 10；The surface (roll surface) of the body of roll 10 is provided with some helical grooves 16, in bearing The side of seat 4 is provided with for the oil nozzle 3 to bearing 6 oiling；It is respectively arranged with outside framework oil seal 8 and skeleton in the both sides of bearing 6 Oil sealing 8 ', is respectively arranged with metal in the outside of outside framework oil seal 8 and outside framework oil seal 8 ' and folds ring sealing group 9 and the folded ring sealing group of metal 9’.

Wherein, the outside folding ring sealing group in metal is provided with transparent cover, and transparent cover is fixedly connected with the bearing seat by bolt.Just It is to say, the outside folding ring sealing group 9 in metal is provided with transparent cover 2, and transparent cover 2 is fixedly connected with bearing block 4 by bolt 1；In gold The outside belonging to folded ring sealing group 9 ' is provided with transparent cover 2 ', and transparent cover 2 ' is fixedly connected with bearing block 4 by bolt.

Wherein, bearing 6 side away from the described body of roll 10 is provided with locating ring 5, is only provided with the outside of locating ring 5 Washer 11 and round nut 12.

In this utility model, because the internal cooling of the body of roll 10 adopts pressure-air cooling, therefore the inside of the body of roll 10 sets Put two hole passages 14 and passage 14 ', passage 14 is connected with breather 15, and passage 14 ' is connected with through-hole pipe 15 ', Wherein, the gas outlet of through-hole pipe 15 and through-hole pipe 15 ' is all oppositely arranged with bearing block.That is, body of roll compressed air inside Cooling, using bilateral air agreement, give vent to anger in eight roads, the cooling of venthole aiming axis bearing and purging oxide skin etc., solves leak shutdown and asks Topic.

In one specific embodiment of this utility model, the surface of the body of roll 10 is provided with some helical grooves 16, spiral The design of groove 16, by increasing capacitance it is possible to increase air knife film-cooled heat, reduces and tropical contact area, reaches more preferable cooling effect.

In one specific embodiment of this utility model, be internally provided with mandrel 13 in roll neck 17, bearing block 4 pass through into Enter the cooling water cooling of described mandrel 13.That is, bearing block 4 cools down still using cooling water cooling it is contemplated that gas circuit is cold But, Selection of Bearings big clearance bearing and the high bearing of high temperature resistance grade.

In addition, in embodiment of the present utility model, bearing block 4 sealing uses and sets respectively at the two ends of bearing block 4 It is equipped with outside framework oil seal 8 and outside framework oil seal 8 ', and is provided with metal outside outside framework oil seal 8 and fold ring sealing group 9, in outside framework oil seal It is provided with metal outside 8 ' and folds ring sealing group 9 ', even if outside framework oil seal 8 and outside framework oil seal 8 ' damage, also can keep grease lubrication Normally.Meanwhile, metal folds ring sealing group 9 ' and metal is folded ring sealing group 9 and deadened the debris such as extraneous iron scale entrance bearing 6 Interior.

Wherein it is desired to explanation, the concrete structure of above-mentioned one end for roll neck of the present utility model, of the present utility model The structure of the both sides of roll neck is identical, then the structure of the roll neck other end no longer repeats one by one.

Additionally, in embodiment of the present utility model it is contemplated that measurement roller assembling online may damage, change often be with Support connection pipe fitting to be removed up and down together is more, arduously time-consuming, and measurement roller therefore of the present utility model adopts split type knot Structure, that is, measure roller and be assembled into individual components, be bolted during design, faying face water flowing adopts O-ring to seal.During replacing Only tear roller assembling open, very simply light and handy.And, the size of body of roll design originally is φ 140x400, through measuring and calculating, the body of roll Now be changed to φ 200x400, bearing when so working, seal from the torrid zone slightly remote some, also increase the wear-resistant time measuring roller And anti-deformation.

Useless measurement roller is pushed away by the ESP producing line that above-mentioned embodiment can be seen that this utility model offer, adopts inside the body of roll With pressure-air cooling, bilateral air agreement, give vent to anger in eight roads, the cooling of venthole aiming axis bearing and purging oxide skin etc., solves leak Halting problem；Roll surface is provided with helical groove, increases air knife film-cooled heat, reduces and tropical contact area, optimizes cooling effect； Bearing block increases metal on the basis of being sealed in original outside framework oil seal and folds ring sealing group, reinforces the effect of sealing, and can deaden The debris such as extraneous iron scale enter in bearing.

Above with reference to accompanying drawing describe in an illustrative manner according to the utility model proposes ESP producing line push away useless measurement roller. It will be understood by those skilled in the art, however, that the ESP producing line being proposed for above-mentioned this utility model pushes away useless measurement roller, also may be used To make various improvement on the basis of without departing from this utility model content.Therefore, protection domain of the present utility model should be by The content of appending claims determines.
