Definitions
- the invention refers to a sealing technique and may be used for the sealing of moving elements with diverse profiles of pressing surfaces.
- the most similar analogue is the method of sealing of moving elements realized in a rotary screw hydraulic motor, according to the method the sealing between a metal rotor and a stator is performed with the fixing of the elastic membrane, for example, made of rubber, fastened on the stator and mounted on the rotor, with rotation capability of a rotor in relation to it.
- Screw downhole motors Reference book - M.: OJSC Nedra Publishing office, 1999, 375 page; Patent RU N° 2011778, IPC E 21 B 4/02 dated 30.04.1994; Patent RU J S 2119035, IPC E 21 B 4/02 dated 20.09.1998), but they appear from them, become known, are disclosed in regard to the part where the operation (performance) of these ma- chines is described. These methods are at the heart of the principle of the operation of these machines under review. The methods drawn out from the reference data (Baldenko D.F., Baldenko F.D., Gnoevykh A. Screw downhole motors: Reference book - M.: OJSC Nedra Publishing office, 1999, 375 page; Patent RU JYS 2011778, IPC E 21 B 4/02 dated
- Patent RU JNs 2119035, IPC E 21 B 4/02 dated 20.09.1998) are the means of the same purpose as the proposed invention in regard to the method, the methods are characterized with accumulation of features, the most similar with the accumulation of essential features of applied for object in regard to method.
- ibidem Patent RU JN° 21 19035, IPC E 21 B 4/02 dated 20.09. 1998 the device applied in a rotary screw hydraulic motor in which as a contact springy sealing aid between a metal rotor and a stator the elastic membrane fastened on the stator and mounted on the rotor, with rotation capability of a rotor in relation to it, is used.
- the elastomer-rubber has such ineffective mechanical- and-physical characteristics, for example in comparison with steel, as a high coefficient of friction for the pair rubber-steel, low tensile strength, low heat-resistance (Patent RU N° 2145012, IPC F 16 F 15/00 dated 27.01.2000 and Chemical Encyclopedic Dictionary / Head editor I. L. Knunyants - Moscow: Soviet encyclopedia, 1983. - 791 page).
- sealing aids applied in them are characterized by increased wear, reduced strength, reduced heat-resistance, not wide range of temperatures and pressures for the operation, impossibility of efficient management of temperature of sealing aid for the constant maintenance of its operational temperature, the exception of its overheat what can result in rubber failure, impossibility of efficient management of hold-down of sealing aid for the constant maintenance of reliable pressurization in the contact point, the usage of rubber for the sealing of moving elements in the devices impairs effectiveness and reliability of pressurization and reduces performance factor of the devices.
- the engineering problem of invention is the implementation of a new method of sealing of moving elements and the device for its realization, which remove the within-named disadvantages of known objects providing the improvement of effectiveness and the sealing reliability; the improving of performance factor of the devices used a proposed invention.
- a contact springy sealing aid between moving elements;
- the multi-layer sealing aid which has the number of layers not above six formed with springy strips of a strong material, for example of metal, which are able to flex under the forcing in accordance with a shape of pressed parts is used , the maintenance of operational temperature in multi-layer sealing aid and the transfer of pressure to the pressed parts of a moving element is arranged by means of cooling medium.
- the operational temperature of multi-layer sealing aid is maintained with the cooling medium supply arrangement with one of the following options.
- the operational temperature of multi-layer sealing aid is maintained with the cooling medium supply arrangement through all the layers at the same time.
- the operational temperature of multi-layer sealing aid is maintained with the cooling medium supply arrangement in a sequential order from a layer to a layer.
- the operational temperature of multi-layer sealing aid is maintained with the arrangement of two separate moving streams of two cooling media in such a manner that media are moving in neighboring layers in a sequential order alternately according to loop- shaped path of motion.
- liquid or gas in case of usage of one cooling medium as a cooling medium the liquid or gas is used, in case of usage of two cooling media a couple of media either liquid-liquid, or liquid-gas, or gas-gas is used.
- the hold-down ?i is developed within limits of greater than or equal to P 2 and less than P 3 , where P 2 - pressure of an isolated space, P 3 - pressure meeting the limit of elastic deformation of a strip.
- the device for the realization of a proposed method of sealing of moving elements including a contact springy sealing aid contains a thermostatic apparatus, a supercharger and as a contact springy sealing aid contains the multi-layer sealing aid which has the number of layers not above six formed with springy strips of a strong material, for example of metal, which are able to flex under the forcing in accordance with a shape of pressed parts, the springy strips in gaps between layers of which are spring-controlled and the opposite side butt-ends of strips of which are hermetically fixed to side springy sliding plates, the oppo- site end butt of strips are fastened with end springy sliding plates, meanwhile springy sliding plates are furnished with suitable holes depending on the arrangement of the moving of cooling medium.
- the device For the case of usage one cooling medium - liquid or gas - the device contains a thermostatic apparatus and a supercharger, for the case of two cooling media - either a cou- pie liquid-liquid, or a couple liquid-gas, or a couple gas-gas - the device contains a supercharger and a thermostatic apparatus for each medium separately.
- the device for the sealing of moving elements 1 has a thermostatic apparatus 2, a supercharger 3, a four-layer sealing aid 4, containing springy strips 5, springs 6, plates 7.
- the invention is realized as follows.
- a multi-layer sealing aid 4 containing springy strips 5 and springs 6 between them to provide free passage of cooling medium, which strips butts 5 are fastened on the plate 7 with the possibility of moving of these ends in one moving plane in order to enhance the effectiveness of strips sag, the tightness of strips to hold-down surfaces is mounted between two moving elements 1.
- the operational temperature of a multi-layer sealing aid 4 is maintained with the cooling medium supply arrangement with one of the abovementioned options using the suitable type of a device, in which springy sliding plates 7 furnished with suitable holes depending on the arrangement of the moving of cooling medium.
- a thermostatic apparatus 2 and a supercharger 3 By means of a thermostatic apparatus 2 and a supercharger 3 the supply and circulation of cooling medium in a multi-layer sealing aid 4 is carried out, as well as the operational temperature is maintained and hold-down is transferred to the outer strip 5, which is contacting with a moving element 1. Meanwhile hold-down Pj is developed within limits of greater than or equal to P 2 and less than P 3 .
- the specified range of pressures is substantiated that at Pi less than P 2 the pressure in an isolated space overpowers hold-down and the seal failure takes place, and at Pj greater than or equal to P 3 for a metal strip the elastic range ends, and a plastic deformation is developed, that also results in the seal failure.
- the device For the case of usage of one cooling medium - liquid or gas - the device contains a thermostatic apparatus and a supercharger, for the case of usage of two cooling media - either a couple liquid-liquid, or a couple liquid-gas, or a couple gas-gas - the device contains a supercharger and a thermostatic apparatus for each medium separately.
