Seal ring keeps the termination section (front end) of body 24, as shown in Figure 4, is made of with the 2nd embedding part 24b cylindraceous that links to each other with its cardinal extremity (rear end) the 1st embedding part 24a cylindraceous.The external diameter of two embedding part 24a, 24b is consistent, and the internal diameter of the 1st embedding part 24a is set to larger than the internal diameter of the 2nd embedding part 24b, and the inner peripheral surface 24h of the inner peripheral surface 24g of the 1st embedding part 24a and the 2nd embedding part 24b is linked by the planar annular 24i with the axial direction quadrature.This planar annular 24i, as shown in Figure 4, by termination face (front-end face) formation of the 2nd embedding part 24b.
The annular recess 24c that base end part 23c, the 23d of seal ring main body 23 is chimeric as shown in Figure 4, is made of interior all zones of the 1st and the 2nd embedding part 24a, 24b.The internal diameter of the 1st embedding part 24a be set to can with seal ring main body 23 the 1st by the chimeric size of embedding part 23c, the internal diameter of the 2nd embedding part 24b be set to can with seal ring main body 23 the 2nd by the chimeric size of embedding part 23d.
Seal ring keeps base end part (rearward end) 24d, the 24e of body 24, as shown in Figure 4, engaging keeps ring sealing part 17 in being formed at the annular groove 24f of interior perimembranous, is remaining on the sleeve 13 so that the mode that can move along axial direction is chimeric under the state that clips ring-like sealed member 17.In this embodiment, seal ring keeps the base end part of body 24, as shown in Figure 4, is configured with being separated into main part 24d and spring receiving portion 24e.Main part 24d is and outstanding above-mentioned embedding part 24a, 24b consists of integratedly from the periphery edge of its termination face (front-end face) 24j that having can be along the axis internal diameter chimeric with sleeve 13 movably.The internal diameter of main part 24d is set to, as shown in Figure 4, produce between the outer circumferential face 13d of side face 24r and sleeve 13 within it can make main part 24d can not rock on the outer circumferential face 13d of sleeve 13 along the small gap of the degree of the smooth and easy movement of axial direction.That is, the internal diameter of main part 24d is set to, and can make main part 24d according to chimeric with common " Spielpassung (movable fit) " equal chimeric degree and sleeve 13.Like this, it is micro-gap that seal ring keeps the gap (being the gap between the outer circumferential face 13d of the inner peripheral surface 24r of main part 24d and sleeve 13 definitely) in the telescoping part of body 24 and sleeve 13, thereby the two 13,24 had better not be made of the metal not of the same race that thermal expansion coefficient differs widely.For example, be the occasion in high temperature fluid zone at machine inner region A, if seal ring keeps body 24 to be made of than sleeve 13 little metallic material thermal expansion coefficient, then the two 13, the missionary society of the heat distortion amount that 24 footpath makes progress causes above-mentioned gap to disappear, so that seal ring maintenance body 24 can't be along the smooth and easy movement of axial direction, on the contrary, if seal ring keeps body 24 to be made of than sleeve 13 large metallic material thermal expansion coefficient, then the two 13, the missionary society of the heat distortion amount that 24 footpath makes progress causes above-mentioned excesssive gap, seal ring can produce when keeping body 24 to move towards axial direction and rock, no matter in which kind of occasion, the capital reduces rotating seal ring 16 with respect to the tracing ability of the other side's seal ring (stationary seal ring) 7, and may cause can't be by two seal rings 7, the good sealing function of 16 performances.Therefore, preferably make sleeve 13 and seal ring keep body 24 to be made of the identical or approximate metallic material of thermal expansion coefficient, in this embodiment, sleeve 13 keeps body 24(to comprise spring receiving portion 24e with seal ring) consisted of by identical metallic material (stainless steel etc.).On the other hand, seal ring main body 23, reason owing to its function aspects, can't be by consisting of with sleeve 13 identical type or metallic material similar with it, consisted of by general seal ring material (being silicon carbide in this embodiment) as described above, so, be difficult to avoid and sleeve 13 between produce the poor of radially heat distortion amount.Therefore, as shown in Figure 4, for fear of the difference of such heat distortion amount that cause with interference sleeve 13, the internal diameter of seal ring main body 23 is set as, makes to produce between the outer circumferential face 13d of the inner peripheral surface 23i of seal ring main body 23 and sleeve 13 than slightly large gap, above-mentioned gap (seal ring keeps the gap between the outer circumferential face 13d of the inner peripheral surface 24r of main part 24d of body 24 and sleeve 13).The mobile gesture of the axial direction on the sleeve 13 of rotating seal ring 16 keeps body 24 and the chimeric form of sleeve 13 to decide by seal ring, so even if the gap of 13 in seal ring main body 23 and sleeve becomes greatly also fully no problem more or less.
Rotating seal ring 16, be used for making seal ring main body 23 and seal ring to keep the annular recess 24c of body 24 physically chimeric, thereby O RunddichtringO 25 is become and radially in opposite directions side face 23f, 24g and the in opposite directions end face 23g of axial direction, the state that 24i flexibly contacts, and seal ring main body 23, seal ring keep the chimeric following of body 24 to carry out.
Namely, little with the 2nd diameter of section that is set as under the nature (not acting on the state of compression load and tension load) than O RunddichtringO 25 by the spaced radial of the outer circumferential face 23f of embedding part 23d the inner peripheral surface 24g of the 1st embedding part 24b, O RunddichtringO 25 between above-mentioned inner and outer circumferential surfaces (in opposite directions side face radially) 23f, 24g than nature compression established amount, pushed the namely zone of interior week of embedding part 24a, 24b of annular recess 24c that (being pressed into) seal ring keeps body 24 by embedding part 23c, 23d with seal ring main body 23 under this state.Described pushing has been compressed in the 1st at O RunddichtringO 25 and finished by the moment between the in opposite directions end face of embedding part 24b (the in opposite directions end face of axial direction) 23g, 24i by embedding part 23c and the 2nd.That is, described pushing finished in the moment that the complete cycle of O RunddichtringO 25 contacts with in opposite directions end face 23g, 24i.
And seal ring main body 23, seal ring keep body 24 under chimeric as described above state, and its telescoping part is by sealing with radially in opposite directions side face 23f, 24g and the in opposite directions end face 23g of axial direction, the O RunddichtringO 25 that 24i flexibly contacts.The sealing function mainly obtains by O RunddichtringO 25 and in opposite directions side face 23f radially, the contact action of 24g, also auxiliarily obtains by O RunddichtringO 25 and the in opposite directions end face 23g of axial direction, the contact action of 24i.
So, because the inner peripheral surface 24g of the 1st embedding part 24a is formed the cylndrical surface that is concentric with the 2nd by the outer circumferential face 23f of embedding part 23d, so as mentioned above, by O RunddichtringO 25 is clipped in this inner and outer circumferential surfaces 23f under compressive state, push the annular recess 24c that seal ring keeps body 24 between 24g and in lower seal ring main body 23 of this state, make thus the complete cycle of the O RunddichtringO 25 that non-compression elastic material makes and radially in opposite directions side face 23f, 24g contacts equably, the result, seal ring main body 23, seal ring maintenance body 24 can be not chimeric under the inconsistent state of axis, and will inevitably be chimeric under concentric state.That is, O RunddichtringO 25, in the above-mentioned sealing function of performance, also performance makes seal ring main body 23, seal ring keep body 24 to carry out chimeric locating function under the consistent state of axis.In addition, rotation side sealing end face 23a with by embedding part 23c, interface between 23d (with the 1st face that is linked by the outer circumferential face 23f of embedding part 23d by the outer circumferential face 23e of embedding part 23c and the 2nd) 23g and with embedding part 24a, interface between 24b (face that the inner peripheral surface 24h of the inner peripheral surface 24g of the 1st embedding part 24a and the 2nd embedding part 24b is linked) 24i is formed on the planar annular with the axis quadrature, so, as mentioned above, in seal ring main body 23 towards moment that pushing of annular recess 24c is through with, the in opposite directions end face 23g of the complete cycle of the O RunddichtringO 25 that non-compression elastic material is made and axial direction, the 24i even contact, the result, seal ring main body 23, seal ring maintenance body 24 just can not be chimeric under the inconsistent state of their axis, and will inevitably be at rotation side sealing end face 23a and above-mentioned in opposite directions end face 23g, chimeric under the state of 24i and identical axis quadrature.That is, the O RunddichtringO has played so that the mode that the seal face 23a of seal ring main body 23 and seal ring keep the axis quadrature of body 24 and form concentric planar annular is used for seal ring main body 23, seal ring are kept the chimeric locating function of body 24.
Therefore, also be not limited to a rotating seal ring 16 and be separated into seal ring main body 23 and seal ring maintenance body 24 ground formation, keep body 24 physically chimeric and form the such composite construct of one seal ring main body 23, seal ring, can be by the above-mentioned locating function of O RunddichtringO 25, rotating seal ring 16 correctly is assembled into the parts same with integrally formed phase, its assembling operation does not need the skilled of height yet, can easily carry out.In addition, because seal ring main body 23, seal ring keep body 24 across the 25 chimeric links of O RunddichtringO, that is to say, radially chimeric carried out across O RunddichtringO 25, so, can as the described situation seal ring main body, seal ring being kept the body link by shrink fit of literary composition head, not be out of shape because seal ring main body 23, seal ring being kept body 24 chimeric seal ring main body 23 and even the rotation side sealing end face 23a of causing.And then, because seal ring main body 23, seal ring keep the material of body 24 different, so in the inferior occasion of high temperature condition, seal ring main body 23, seal ring keep the telescoping part of body 24 to occur sometimes radially and/or the significant heat distortion amount of axial direction poor, but, the problem that the difference of this heat distortion amount causes can be prevented by the resiliently deformable (pooling feature) of O RunddichtringO 25, even if also can suitably guarantee the function of rotating seal ring 16 under harsh temperature conditions.For the pooling feature of the such O RunddichtringO 25 of effective performance and above-mentioned locating function (below be referred to as " O RunddichtringO function "), must O RunddichtringO 25 be seated in the telescoping part that seal ring main body 23 and seal ring keep body 24 allowing under the state that produces the resiliently deformable that radially reaches axial direction in the mode that can bring into play O RunddichtringO function.Therefore, in this embodiment, keep in the telescoping part of body 24 at seal ring main body 23 and seal ring, as shown in Figure 4, the two 23,24 namely the 1st of seal ring main body 23 the kept between the inner peripheral surface 24g of the 1st embedding part 24a of body 24 by the outer circumferential face 23e of embedding part 23c and seal ring between side face in opposite directions, and seal ring main body 23 the 2nd by between the inner peripheral surface 24h of the 2nd embedding part 24b of the outer circumferential face 23f of embedding part 23d and seal ring maintenance body 24, form gap (gap radially), this gap is, radially (above-below direction among Fig. 4) of allowing O RunddichtringO 25 to be can bringing into play the mode generation resiliently deformable of O RunddichtringO function, and the two 23,24 can not produce rock along relatively move the swimmingly gap of degree of (can seal ring main body 23 swimmingly the chimeric recess 24c of embedding sealing ring holder 24) of axial direction.In addition, keep in the telescoping part of body 24 at seal ring main body 23 and seal ring, as shown in Figure 4, in the two 23,24 namely the 2nd of seal ring main body 23 the kept by cardinal extremity face (ear end face) 23j of embedding part 23d and seal ring between the termination face 24j of main part 24d of body 24 between end face in opposite directions, such as described later, form and to allow that O RunddichtringO 25 is with the mode that can the bring into play O RunddichtringO function enough gaps along axial direction (left and right directions among Fig. 4) resiliently deformable.
In addition, to keep the axial direction length (the axial direction degree of depth) of the chimeric recess 24c of body 24 to be set to larger than the axial direction length of base end part 23c, the 23d of seal ring main body 23 for seal ring.That is, as shown in Figure 4, be constituted as, keep in seal ring main body 23, seal ring under the chimeric status of body 24, in the 2nd gap that is kept some axial directions of existence between the termination face 24j of main part 24d of body 24 by the ear end face 23j of embedding part 23d and seal ring.Therefore, in the occasion to the too much axial direction compressive force of rotating seal ring 16 effects, namely the axle direction thrust too high occasion of rotating seal ring 16 towards stationary seal ring 7 pushings, the resiliently deformable of O RunddichtringO 25 changes the axial direction interval of in opposite directions end face 23g, the 24i of axial direction, and this axial direction compressive force is relaxed.That is, O RunddichtringO 25 has played and can not become too high and pooling feature that adjust for two seal face 7a, 23 surface of contact are pressed.
In addition, seal ring main body 23, seal ring keep body 24 by with the friction apply power of the O RunddichtringO 25 that is clipped in its telescoping part be used for stoping relative rotation, and in this embodiment, as shown in Figure 4, rearward end (the 2nd by the rearward end of embedding part 23d) in seal ring main body 23 forms engaging recessed part 23h, and keep the termination face 24j of the main part 24d of body 24 to give prominence to the driving pin 24p that setting engages with engaging recessed part 23h at seal ring, be used for by the two 23h, the snap action of 24p further stops seal ring main body 23 reliably, seal ring keeps the relative rotation of body 24.The engaging of the two 23h, 24p is along with seal ring main body 23 is pushed and will inevitably occur towards annular recess 24c.
Linking member 5, as shown in Figures 2 and 3, be used for Stationary side seal element 3 is connected to the form identical with the use form (form shown in Figure 1) of mechanical sealing element with rotation side sealing element 4 temporarily, metal plate 27 is set by a plurality of (only illustrating 1), be used for the base end part that plate 27 respectively is set be fixed on the bolt 28 of the termination section (front end) of mounting box 6, the annular recess 13c that is formed on the 13a of termination section of sleeve 13 consists of.Annular recess 13c, as shown in Figures 2 and 3, two seal elements 3,4 are positioned in the situation of position relationship with the position of the use homomorphosis of mechanical sealing element on its axial direction, to be positioned at the mode of the position that the termination section that plate 27 respectively is set on the mounting box 6 that is installed in engages, be formed on the peripheral part of the 13a of termination section of sleeve 13.In addition, the degree of depth of annular recess 13c is configured to, can be under the state that is installed in the termination section that plate 27 respectively is set on the mounting box 6 and its bottom surface butt, so that the mode of the use homomorphosis of two seal elements 3,4 position relationship radially and mechanical sealing element links two seal elements 3,4.The quantity of plate 27 is set, for two seal elements 3,4 to link along axial direction and radially the position relationship mode with the use homomorphosis of mechanical sealing element, needs are preferably more than 3 more than 2.In addition, the circumferentially spaced equal intervals that plate 27 is preferably in mounting box 6 being set installs.In this embodiment, the plate 27 that arranges that 4 (only illustrating 1) stainless steels are made is installed in the circumferentially spaced equal intervals of mounting box 6.
The mechanical sealing element that consists of as described above, the boxlike that is assembled in the following order use form sealing function and mechanical sealing element (form shown in Figure 1) same modality that can bring into play regulation is constructed.
At first, clip O RunddichtringO 11a, the chimeric stationary seal ring 7 in 11b ground at the interior perimembranous 6a of mounting box 6, assembling Stationary side seal ring element 3.
Then, after assembling rotating seal ring 16, this rotating seal ring 16 inserted from the 13a of its termination section lead to sleeve 13, and, spring members 18 between rotating seal ring 16 and spring holder 15, loaded.The assembling of rotating seal ring 16 is by carrying out among the annular recess 24c that seal ring main body 23 is fitted to seal ring maintenance body 24, as mentioned above, keep the telescoping part of body 24 to clamp O RunddichtringO 25 at seal ring main body 23, seal ring, so, keep the chimeric link of carrying out of body 24 not need the proficiency of height by seal ring main body 23, seal ring, can easily and accurately carry out.
And, so, the sleeve 13 that has loaded rotating seal ring 16 and spring members 18 in rearward end 13b side, from the slotting Stationary side seal element 3 that leads to of the rearward end 6c side of mounting box 6, at the chimeric stopper ring 20 of the 13a of termination section towards the outer outstanding sleeve 13 of mounting box 6, then, fastening the 1st screw 21a and stopper ring 20 is fixed on the 13a of termination section of sleeve 13.
And then, by bolt 28 plate 27 that respectively arranges that is stuck close in the chimeric recess 13c of sleeve 13 is installed on the mounting box 6, assemble rotatable seal element 4 and two seal elements 3,4 are linked (with reference to Fig. 3).
This two seal element 3,4 link form, for the form of the use homomorphosis of mechanical sealing element, by two seal elements 3,4 are linked the assembling of finishing mechanical sealing element.
The assembling operation of such mechanical sealing element, outside rotating equipment, carry out, and be installed on the mounting box 6 by the plate 7 that arranges that handle engages with annular recess 13c, thereby two seal elements 3,4 so that its axial direction and radially position relationship become the mode of the use form of mechanical sealing element links, so do not need the skilled of height, can easily and correctly carry out.
And, two seal elements 3,4 of the use form that is assembled in this wise mechanical sealing element, as shown in Figure 3, insert and lead to running shaft 2, and, the slotting bolt 8 of giving prominence to from shaft seal section case 1 that leads to of each bolt hole 6b of mounting box 6, as shown in Figure 2, the fastening nut 9 that is screwed up on each bolt 8 is installed to mounting box 6 on the shaft seal section case 1, thereby, can under the state of the use form that connects to mechanical sealing element, be assembled into two seal elements 3,4 on the rotating equipment.
And, after being installed to mounting box 6 on the shaft seal section case 1, the fastening the 2nd arranges screw 21b and stopper ring 20 is fixed to (with reference to Fig. 2) on the running shaft 2, and then, plate 27 is set finishes the assembling (with reference to Fig. 1) of mechanical sealing element towards rotating equipment by pulling down.
Such mechanical sealing element is towards the assembling operation of rotating equipment, this mechanical sealing element is assembled into form with the use homomorphosis of mechanical sealing element in advance as described above, so, with two seal elements 3, each component parts of 4 separately the occasion of assembling compare very easy, even if unskilled person assembly failure can not occur yet, can suitably assemble.
Therefore, based on the mechanical sealing element that is assembled into like this, although rotating seal ring 16 keeps body 24 to link by seal ring main body 23 and seal ring, also with by shrink fit seal ring main body 23, the occasion that seal ring keeps body 24 to link is different, can not produce distortion in seal ring main body 23 and the seal face 23a that forms thereon, in addition, as the seal face 7a of stationary seal ring 7 with the in opposite directions end face of rotating seal ring 16, parallel with suitable face press contacts of 23a, relatively rotation can be passed through sealing end face 7a under the concentric, the relative rotational slide contact action of 23a is carried out excellent sealing to sealed fluid mass A and atmosphere zone B.
So, because the fluid pressure of sealed fluid mass A acts on the rotating seal ring 16 as back pressure, so when sealed fluid mass A becomes high pressure because of pressure oscillation etc., this back pressure so that the pushing force of 16 pairs of stationary seal rings 7 of rotating seal ring (acting on the axial direction thrust on the rotating seal ring 16) uprise, the surface of contact of two seal face 7a, 23a is pressed higher than needs of becoming, and the problem of the abnormal wear, heating etc. of seal face 7a, 23a may occur.But, as mentioned above, under the pooling feature effect that the resiliently deformable (compressive strain) of the O RunddichtringO 25 between in opposite directions end face 23g, the 24i of the axial direction in the telescoping part that is loaded in seal ring main body 23 and seal ring maintenance body 24 produces, the pushing force of 16 pairs of stationary seal rings 7 of rotating seal ring that back pressure produces is relaxed, that is to say, the axial direction compressive force that acts on the rotating seal ring 16 is relaxed, and the surface of contact of two seal face 7a, 23a is pressed and suitably kept.In addition, because O RunddichtringO 25 is made of incompressibility elasticity material, so the resiliently deformable of above-mentioned O RunddichtringO 25 (compressive strain of axial direction) so that 25 pairs of seal ring main bodys 23 of O RunddichtringO, seal ring keep in the body 24 radially in opposite directions the contact of side face 23f, 24g press and uprise, that is to say, improved the sealing force that O RunddichtringO 25 pairs of seal ring main bodys 23, seal ring keep the telescoping part of body 24, even if sealed fluid mass A becomes high pressure, seal ring main body 23, seal ring keep the telescoping part of body 24 also can access excellent sealing.In addition, in above-mentioned mechanical sealing element, as shown in Figure 1, by from the opening portion 12a of flushing path 12 towards the suitable washing solution of two seal face 7a, 23a ejection, quenching liquid cooling liquids such as () clear water 12b, thereby prevent from as far as possible following abnormal wear that the relative rotational slide contact of two seal face 7a, 23a produces, heating etc.
In addition, from rotating equipment dismounting mechanical sealing element, can by with assemble opposite order towards above-mentioned rotating equipment and carry out, can equally easily carry out with this assembling.That is, by plate 27 respectively is set two seal elements 3,4 are linked, then, screw 21b is set to the 2nd and unclamps, releasing stopper ring 20 is fixing towards running shaft 2, and, mounting box 6 is pulled down from shaft seal section case 1, thereby just can all directly be pulled down mechanical sealing element from rotating equipment.Like this, by two seal elements 3,4 are installed and removed rotating equipment under the state that connects to the form of the use homomorphosis of mechanical sealing element, can carry out easily so that comprise the assembling of mechanical sealing element and the upkeep operation that decomposes.In addition, even if the seal face 23a of rotating seal ring 16 abrasion or damage, also just change the seal ring main body 23 that is formed with seal face 23a and get final product, do not need to change the integral body of the rotating seal ring 16 that comprises seal ring maintenance body 24, can seek to cut down maintenance cost.And, since rotating seal ring 16 seal ring main body 23 chimeric with seal ring maintenance body 24 under the state of O RunddichtringO 25, so the replacing operation of seal ring main body 23 also can easily be carried out.
Therefore, spring holder 15 can be constituted as, and be fixed on the sleeve 13 by screw is set as the individual components that separates with sleeve 13, but so, sleeve 13 is thin-walled, just may cause the generation of following problem.That is, if sleeve 13 is thin-walled, the fastening situation that screw is set may cause sleeve 13 distortion, especially in the situation that the worker is unskilled person, and the fastening screw that arranges exceedingly.Therefore, in the situation that spring holder 15 is fixed on the sleeve 13 by screw is set, must be set as the wall thickness of sleeve 13 greater than certain thickness, so, the diameter that can cause inserting logical stationary seal rings 7 with the chimeric rotating seal ring 16 of sleeve 13 and sleeve 13 becomes excessive, and then causes the become weight of large footpathization, mechanical sealing element of mounting box 6 significantly to increase.
But as mentioned above, if integrally formed with the rearward end 13b of sleeve 13 spring holder 15, then can make as far as possible sleeve 13 be thin-walled, and can not produce the problems referred to above.In addition, when making sleeve 13 for thin-walled, can reduce the outside dimension of the rotating seal ring chimeric with it 16, that is to say, can reduce to give prominence to and be inserted into from mounting box 6 outside dimension of the rotation side sealing element 4 in the shaft seal section case 1, therefore (for example in shaft seal section case 1, loaded the rotating equipment of gland packing, shaft seal section case is the rotating equipment of the Stuffing box structure of filling gland packing) in, do not need other design alteration, transformation, just can easily be altered to gland packing the mechanical sealing element of high sealing function.
In addition, as sleeve fixed component 14, can by being set, screw directly be fixed on the 13a of termination section of sleeve 13 on the running shaft 2, but so, the through hole of screw must be set at sleeve 13, therefore consider to make sleeve 13 to be heavy wall from intensity.But, as mentioned above, if at the chimeric stopper ring 20 of the termination of sleeve 13 13a of, stopper ring 20 is arranged screw 21b by the 2nd be fixed on the running shaft 2, just can make as far as possible sleeve 13 be thin-walled, enjoy the benefit that above-mentioned sleeve thin-walled property brings.
In addition, seal ring keeps body 24 also can be constituted as integrally formed thing, and still, so, the ring sealing part 17 that is maintained among the annular groove 24f just is restricted to the parts that can produce diametrically large resiliently deformable as the O RunddichtringO.But, if as described above, keep seal ring body 24 to be configured with being separated into embedding part 24a, 24b and body 24d, spring receiving portion 24e, that is to say the rearward end opening that can make annular groove 24f, then can ring sealing part 17 not occured from this opening portion 14n to load in the situation of large distortion diametrically.Therefore, as ring sealing part 17, except the O RunddichtringO, at the sealed member that radially can not produce large resiliently deformable (for example can also use, the V word Sealing that the teflon that the cross section is in the shape of the letter V is made etc.), can be according to air-proof condition choice for use ring sealing part 17.
[industrial utilizability]
In the above-described embodiment, the present invention is applicable for passing through two seal face 7a, the relative rotational slide contact action of 23a is brought into play the end contact formula mechanical sealing element of sealing function, but the present invention also can be suitable for and be the non-contact mechanical seal spares such as gas seal, this non-contact mechanical seal spare is constituted as, at seal face 7a, 23a forms the groove of trickle helical etc., make seal face 7a, produce the dynamic pressure that the fluid by sealed fluid mass A forms between 23a, seal face 7a, 23a is held in the contactless state that is formed with betwixt micro-gap.In addition, mechanical sealing element of the present invention can be used for the vertical vertical rotating equipment of the horizontal rotary equipment of running shaft 2 levels and running shaft 2.
