Abstract
Set-load high temperature bellows mechanical seal ring is the mobile components, static Central components, such as corrugated metal pipe components composed of spindle with the front sleeve, bushings on the front of a cylindrical package jets , bushings on the back-end cylindrical ring with dynamic components, dynamic components ring and the other end of corrugated metal pipe connecting components, the use of corrugated metal pipe welding double wave-use corrosion-resistant, heat-resistant chromium Ni-Fe alloys, metal bellows and the other end of components Static ring connecting components; sets installed in the diversion of corrugated metal pipe components, static components of the inner circle ring, sets the right side of diversion set up a gland; pressure cover, set up a floating expenditure lateral bushing. The present invention can transfer high temperature, corrosion, a special dielectric particles circumstances, the pump has played safe, reliable, long life sealing effect.
Description
Technical field: the present invention relates to pallet high-temperature-resisting corrugated pipe mechanical seal.It is applicable to high temperature pump, the oil pump of carrying high temperature, burn into to contain granule medium.
Technical background: mechanical seal for pump, adopt spring type mechanical sealing usually, combination is simple, only is applicable under the normal temperature condition to use.Meet the pump of carrying high temperature, high pressure or granule medium being arranged, even select general bellows mechanical seal for use, rotating ring in the course of the work, stationary ring are because medium temperature height (only needing 250 ℃-300 ℃) causes mechanical seal short working life because of reasons such as the expansion coefficient of material is big produce phenomenons such as " decylizations ", cause leakage, security incident takes place easily and influence environment.It is technician's problem anxious to be solved of the industry.
Summary of the invention: purpose of the present invention will provide a kind of pallet high-temperature-resisting corrugated pipe mechanical seal exactly, it can solve the problem that present mechanical seal for pump exists well, the object of the present invention is achieved like this, pallet high-temperature-resisting corrugated pipe mechanical seal is by moving ring assembly, static components, corrugated metal pipe components, the water conservancy diversion cover, nockbush floats, gland, the larynx cover, axle sleeves etc. are formed, it is characterized in that: the front end of main shaft is provided with axle sleeve, the front end cylindrical of axle sleeve is provided with the larynx cover, the rear end cylindrical of axle sleeve is provided with moving ring assembly, one end of moving ring assembly contacts with the axle sleeve step end face, the other end and corrugated metal pipe components are joined, metal bellows adopts double-deck welding, wave plate is selected for use corrosion-resistant, resistant to elevated temperatures inconel, the other end and the static components of corrugated metal pipe components are joined; Water conservancy diversion is set on the inner ring of corrugated metal pipe components, static components, and the right side of water conservancy diversion cover is provided with gland; The inside front of gland is provided with flushing, quenching apparatus and gland pad, and the gland pad adopts special Expanded graphite composite pad, and the interior side-lower of gland is provided with tapping equipment, and the arranged outside of gland has unsteady nockbush.The present invention can carry high temperature, have burn into to have under the special media situation of particle, and pump is played the seal action safe, reliable, that the life-span is long.
Description of drawings: Fig. 1 is a structural representation of the present invention;
1. moving ring assembly, 2. corrugated metal pipe components, 3. static components, 4. gland, 5. water conservancy diversion cover, 6. float nockbush, 7. gland pad, 8. larynx cover, 9. axle sleeve.
Embodiment: the invention will be further described below in conjunction with accompanying drawing;
In the drawings, pallet high-temperature-resisting corrugated pipe mechanical seal of the present invention is by moving ring assembly 1, static components 3, corrugated metal pipe components 2, water conservancy diversion cover 5, nockbush 6 floats, gland 4, larynx cover 8, axle sleeve 9 is formed, it is characterized in that: the front end of main shaft is provided with axle sleeve 9, the front end cylindrical of axle sleeve 9 is provided with larynx cover 8, the rear end cylindrical of axle sleeve 9 is provided with moving ring assembly 1, one end of moving ring assembly 1 contacts with axle sleeve 9 step end faces, the other end and corrugated metal pipe components 2 are joined, metal bellows 2 adopts double-deck welding, wave plate is selected for use corrosion-resistant, resistant to elevated temperatures inconel, the other end of corrugated metal pipe components 2 and static components 3 are joined; Water conservancy diversion cover 5 is arranged on the inner ring of corrugated metal pipe components 2, static components 3, and the right side of water conservancy diversion cover 5 is provided with gland 4; The inside front of gland 4 is provided with flushing, quenching apparatus and gland pad 7, and gland pad 7 adopts special Expanded graphite composite pad, and the interior side-lower of gland 4 is provided with tapping equipment, and the arranged outside of gland 4 has unsteady nockbush 6.During concrete enforcement; metal bellows adopts double-deck welding; wave plate is selected for use corrosion-resistant, resistant to elevated temperatures inconel; the gland pad adopts special Expanded graphite composite pad; but corrosion protection, anti-450 ℃ of high temperature; the fastness of machine envelope rotating ring, stationary ring, firmly to hard cooperation, adopt unique hot insert technology, guarantee that machine is enclosed in long service life under the worst hot case.Water conservancy diversion is set on the inner ring of corrugated metal pipe components, static components, chilled water (chw) or low service system are played guide functions, improve the chilling effect and prevent chilled water (chw) or low pressure steam directly washing away simultaneously machine envelope bellows inboard, and can take away machine envelope just in case during micro-leakage and the coking or the crystalline solid that bring prevent side clearance in the obstruction machine envelope bellows thereupon.The energy-conservation lining that floats is arranged on the outside of gland, adopts high quality carbon graphite, is designed to radial floating, and the wearing and tearing of compensation graphite bushing can short-term intercept because machine envelope moment catastrophic failure causes the leakage of medium, prevent the security incident generation or influence environment." flushing, chilling " and " discharging " are the auxiliary system devices of machine envelope, because it is general that high temperature pump, oil pump are carried all is high temperature between 300-420 ℃, and have solid and urge medium through agent particle, coking, so adopt cooling and flushing auxiliary device, to reach the Coolers envelope and to prevent that the attached suction of particle in the medium from sealing up at machine.
