Abstract
The invention discloses a sealing member for a runner blade of a motor. The sealing member is arranged between a paddle rotary shaft (1) and an runner body (2), and comprises an oil sealing ring (3) and two water sealing rings (4), which are both V-shaped sealing rings; the V slot of the oil sealing ring (3) faces a water inlet end (6); and the V slots of the two water sealing rings (4) face an oil releasing end (7). The sealing member for the runner blade of the motor has the beneficial effects that one oil sealing ring and two water sealing rings are adopted in the sealing member, the sealing member is consistent with the old sealing structure in amount, and lubricant oil is not leaked and the waterproof effect is improved under the basis of not changing the whole structure.
Description
Technical field
The present invention relates to sealing configuration, particularly relate to a kind of Sealing for motor runner wheel blade.
Background technique
Such as Fig. 1, V-shaped seal ring comprises two sealing lips (5), two sealing lips (5) have a certain degree, form a V groove, V-shaped seal ring generally is used for rotating shaft sealing, a sealing lip (5) applying rotating shaft, the inside of another sealing lip (5) applying housing is when rotating shaft is rotated, if adopt the O RunddichtringO, may be excessive because of frictional force, cause the O RunddichtringO often to damage, and adopt V-shaped seal ring, because the V groove between two sealing lips (5), so that sealing lip (5) pushes when being under pressure, thereby guaranteed working life of V-shaped seal ring in the V groove.
Bulb type generator set is started late in China's research and development, and design deficiency is more.The wheel blade Seal Design of existing bulb-generator adopts reliable V-shaped seal ring; one deck water shutoff; two layers of oil sealing; under guaranteeing that strict Replacement procedure requires; through repeatedly more renewing the wheel blade sealing; all can not get effectively solving the water inlet problem; repeatedly cause lubricant oil water inlet stopping accident; the wheel blade sealing should seal river and not enter web; the lubricant oil that seals again in the web is not leaked in the river; repeatedly changing novel sealing river still occurs and enters web and oily leakage problem do not occur; get rid of assembling and material from the design angle problem analysis; sealing place is apart from 7.1 meters of fuel heads, and apart from 20.5 meters of water surface elevations, hydraulic pressure is higher than oil pressure far away; and river contains silt etc. makes the water shutoff environment be worse than the oil sealing environment far away; and the sealing of water shutoff only has one deck, oil sealing be two layers on the contrary, be the main cause that causes web sealing water inlet.
Summary of the invention
The object of the invention is to overcome the shortcoming and defect of above-mentioned prior art, the Sealing that is used for motor runner wheel blade is provided, it is bad to solve existing bulb type generator set runner wheel blade sealing effect, river occurs easily and enters the interior problem of web.
Purpose of the present invention is achieved through the following technical solutions: the Sealing that is used for motor runner wheel blade, be arranged between blade rotating shaft and the web, comprise an oil seal ring and two watertight seal rings, described oil seal ring and watertight seal ring all are V-shaped seal ring, the oil seal ring is a sealing lip with the watertight seal ring and contacts with the blade rotating shaft sealing, another sealing lip contacts with the inner wall sealing of web, one of them sealing lip that is the oil seal ring contacts with the blade rotating shaft sealing, another sealing lip of oil seal ring contacts with the inner wall sealing of web, one of them sealing lip of watertight seal ring contacts with the sealing of blade rotating shaft sealing, another sealing lip of watertight seal ring contacts with the inner wall sealing of web, the V groove of described oil seal ring is towards feed-water end, and the V groove of two watertight seal rings is all towards the draining end.The old Sealing that is used for motor runner wheel blade adopts two oil seal rings and a watertight seal ring, but sealing place is apart from 7.1 meters of fuel heads, apart from 20.5 meters of water surface elevations, hydraulic pressure is higher than oil pressure far away, so a watertight seal ring does not have good water-proof function, and an oil seal ring has enough stoped oil to leak, so among the present invention, change original two oil seal rings into an oil seal ring, a watertight seal ring changes two watertight seal rings into, do not changing on the integrally-built basis like this, both guaranteeing that lubricant oil do not reveal, promoting again waterproofing effect.
Further, above-mentioned oil seal ring is arranged at the end near feed-water end, and two watertight seal rings all are arranged at an end of close draining end, like this when waterproof, water is first by the oil seal ring, and when grease proofing, oil is first by the watertight seal ring, and the V groove end sealing effect of V-type ring will differ from upper a lot compared with the back side, but also has certain sealing effect, so the oil seal ring is when grease proofing leakage, the V groove face by the watertight seal ring carries out once slightly poor sealing first, and like this also the time during watertight seal ring waterproof.
Further, spaced apart by support ring between described oil seal ring and two the watertight seal rings, the shape of described support ring cooperates with the oil seal ring that touches and water-stop annular shape, guarantee not interact between oil seal ring and the watertight seal ring, because, the V groove of oil seal ring and watertight seal ring all is V groove shape all towards the outer end so support ring touches the end face of oil seal ring and watertight seal ring.
Further, the V groove end of above-mentioned oil seal ring is provided with a pressure ring A, the shape of pressure ring A cooperates with the oil seal ring that touches, be that pressure ring A is the triangle standing shape towards an end of oil seal ring, in the middle of pressure ring A and support ring are clamped in the oil seal ring, thereby the oil seal ring is fixed, and the oil seal ring is under the compressing of pressure ring A and support ring, the edge of sealing lip can contact with sealed fully; Two superimposed arrangements of watertight seal ring, the V groove end of the watertight seal ring of close feed-water end is provided with a pressure ring B, the shape of pressure ring B cooperates with the watertight seal ring that touches, in the middle of pressure ring B and support ring are clamped in two watertight seal rings, thereby two watertight seal rings are fixed, and the effect of pressure ring B is consistent with pressure ring A's.
Further, above-mentioned oil seal ring and watertight seal ring all adopt butyl rubber to make.
Further, two sealing lip angulations of above-mentioned oil seal ring are 80 °, and two sealing lip angulations of watertight seal ring are 80 °, and this angle sealing effect is relatively good.
The invention has the beneficial effects as follows: the Sealing for motor runner wheel blade of the present invention, adopt an oil seal ring and two watertight seal rings, quantitatively consistent with old sealing configuration do not changed on the integrally-built basis like this, both guaranteed that lubricant oil do not reveal, promoted again waterproofing effect.
