Description
Technical field
The utility model relates to water pump mechanical seal and rinses cooling structure, and particularly direct-current transmission converter valve constituent water pump mechanical seal rinses cooling structure.
Background technique
Direct-current transmission converter valve is one of nucleus equipment of direct current transportation, the heat that converter valve is operationally produced, the device temperatures such as valve body can be caused to raise, if do not configure suitable cooling measure, valve body temperature will be made to exceed allowed maximum junction temperature, thus cause device performance degradation and device failure.Due to features such as the thermal conductive resin of pure water and insulating properties, well can be applied to the heat transfer of this high voltage and high power device, thus, adopt the relevant art of pure water cooling also just to arise at the historic moment.Direct-current transmission converter valve constituent adopts pure water cooling technology to solve the secure heat dissipation problem of converter valve under the conditions such as high voltage, strong electrical field, strong jamming, high heat flux, thus when ensureing that device runs, its inner junction temperature remains within the junction temperature of permission.
Early stage direct-current transmission converter valve constituent uses Single Mechanical sealing centrifugal pump to provide power for the whole circulatory system.Mechanical seal is named end face seal again, is to fit in the lower maintenance of elastic force (or magnetic force) effect of hydrodynamic pressure and compensation mechanism to the end face making relative sliding perpendicular to axle by a pair or several and be equipped with auxiliary seal and reach the gland seal device of Drain Resistance.Generally be made up of rotating ring, stationary ring, seal ring of moving ring, stationary ring seal ring, spring, spring seat, Cock screw, stop pin etc.During mechanical seal work, the axial force caused by the elastic force etc. of fluid-encapsulated pressure and elastic element makes rotating ring and stationary ring fit mutually and relative movement, due to closely cooperating of two seal faces, making the boundary between seal face (seal interface) form a micro-gap, when there being piezodielectric by this gap, forming very thin liquid film, produce resistance, stop dielectric leakage, liquid film makes again end face be lubricated simultaneously, obtains long term seal effect.But in direct-current transmission converter valve constituent is run, find direct-current transmission converter valve water-cooling control system often because Leakage of Mechanical Seals in Alumina Plant water sends alarm signal, analyze mechanical seal place percolating water and mainly contain following three kinds of reasons: the dynamic and static plane of a loop of (1) machine envelope is because of reason initiation wearing and tearing such as installation, lack of water or cavitation erosions; (2) mechanical seal glue ageing failure; (3) motor axle journal machining accuracy is poor, size is little, coarse and axle journal corrosion.Under the environmental conditionss such as high voltage, strong electrical field, strong jamming, high heat flux, the reliable operation leaked for converter valve is breakneck factor, so how avoiding pump mechanical seal water to leak is the problem needing solution badly.
Water pump operationally needs to rinse to the direct injection liquid body in position, high pressure side of mechanical seal.The object of rinsing is sealing, Cooling and Lubricator: pass into liquid in (1) sealing Seal cage, thus prevent high temperature media from spilling from pump shaft; Prevent the medium containing solid particle from bleeding in Seal cage, abradable seal face; (2) frictional heat produced when rotating ring and stationary ring work are led away in cooling; (3) lubrication keeps there is one deck liquid film lubricate between sealing surface.Existing mode has three kinds of (1) wet pit endless form, and wet pit endless form is driven by natural circulation or pump, gets back to wet pit, and cooled from Seal cage hydrothermal solution out.Cooled washing solution is got back in Seal cage again, and lubrication is coolant seal face also.After a period of time, because the washing solution in pond by the pollution of pumping liquid, therefore must can be changed it, be not easy to operation, and this system does not process in real time to water quality in wet pit, easily cause corrosion or fouling, damage machine envelope.(2) the acyclic mode of wet pit, washing solution lubrication and seal face, after a period of time, because the washing solution in pond can by the pollution of pumping liquid, therefore must change it, this system is not dispelled the heat.(3) outside washing solution system, washing solution rinses Seal cage, then enters gutter.Washing solution can effective cooling lubrication and seal face, and which is unfavorable for cleaner production.In sum, above three kinds of backwashing manners are not optimal selections.
Model utility content
The purpose of this utility model is the shortcoming overcoming above-mentioned prior art, provides a kind of direct-current transmission converter valve constituent water pump mechanical seal to rinse cooling structure.
The purpose of this utility model is achieved through the following technical solutions:
Direct-current transmission converter valve constituent water pump mechanical seal rinses cooling structure, comprise machine envelope cooling chamber intake pipe and machine envelope cooling chamber outlet pipe, described machine envelope cooling chamber intake pipe access exit of pump flange hole, machine envelope cooling chamber outlet pipe access unit fixed on water pump suction flange hole, described machine envelope cooling chamber intake pipe is provided with ball valve, is used for the flow of conditioner seal cooling water.
In order to better realize the utility model, described machine envelope cooling chamber outlet pipe comprises one section of metallic hose, because machine envelope cooling chamber outlet pipe will stride across FlexbleJoint, is improved the flexibility of pipeline by metallic hose.
In order to better realize the utility model, described unit fixed on water pump suction flange hole is welded with ball valve, and ball valve seals cooling chamber outlet pipe by ferrule fitting and machine and is connected, and facilitates changing machine to seal after Cutoff ball valve.
In order to better realize the utility model, described machine envelope cooling chamber intake pipe is provided with choke apparatus, in order to reduce the pressure of machine seal cooling water.
In order to better realize the utility model, described mechanical seal adopts two mechanical seal series connection.
In order to better realize the utility model, described mechanical seal material is silicon carbide.
Compared with prior art, tool has the following advantages and beneficial effect the utility model:
(1) adopt the cooling of water pump fed sheet of a media to carry out flushing cooling to machine envelope, because water pump fed sheet of a media is through the pure water after ion exchange resin treatment, so pollute very little to machine envelope, there will not be corrosion and scale problems; Structure is simple on the other hand, without the need to external cooling device, cost-saving; Again on the one hand without the need to changing or discharge flushing cooling liquid, be conducive to cleaner production;
(2) adopt the form of two single mechanical end face seal series connection, improve the reliability of mechanical seal;
