Description
Technical field
The present invention relates to pump for liquid salts apparatus structure fields, in particular to a kind of effluent seat of pump for liquid salts.
Background technique
It requires in metallurgy, chemical industry, solar light-heat power-generation and energy storage field using the fused salt circulatory system, pump for liquid salts is
Essential key power-equipment in the fused salt circulatory system.Its feature is exactly to convey high-temperature molten salt medium, each under hot conditions
A critical component can all generate certain deformation, can have an impact to the levelness of the installation of other components and to center, thus
Generate de-stabilising effect factor.Effluent seat is the portion of unique and high-temperature liquid state fused-salt medium contact in pump for liquid salts unit supporting structure
Part, the critical issue of pump for liquid salts set steady are that displacement and deformation, meeting can be generated under the influence of high temperature by installing support member
Influence unit operation stability.
Pump for liquid salts critical support component effluent seat annular pumping chamber and surrounding components structure interconnect in the prior art, Yin Wen
Degree factor can cause the deformation of surrounding structure, especially bearing housing base-plate to be deformed under the influence of high temperature, directly result in
The service life of bearing is reduced, and the influence that the support member contacted with annular pumping chamber is deformed by annular pumping chamber, is led
Pump for liquid salts set steady is caused to be deteriorated.And pump for liquid salts effluent seat pumps effluent seat, bulky, waste of resource using core.
Through retrieving, the selection of document solar energy thermal-power-generating field high-temperature melting salt pump and application (the solar energy thermal-power-generating such as Liu Lei
The selection of field high-temperature melting salt pump and apply [J] universal machine, 2018 (12): 14-15.) elaborate pump for liquid salts in light in a text
Selection and application in heat power generation, do not propose to improve to structure division.(kingly way is red for a kind of vertical high-temperature long axis pump for liquid salts of document
A kind of equal vertical high-temperature long axis pump for liquid salts [P] .ZL201420829104.9. of) in the pump for liquid salts that proposes using not improving
Water leak seat structure.That is the prior art does not overcome the above problem.
Summary of the invention
It is an object of the present invention to provide a kind of pump for liquid salts effluent seats, it can solve the above technical problem.
The technical scheme adopted by the invention is that: a kind of effluent seat of pump for liquid salts, comprising: support baseboard is fixedly connected on
Annular pumping chamber, bearing housing base-plate, water outlet on support baseboard；It is characterized in that: the support baseboard passes through support
Gusset is connect with bearing housing base-plate；It is disposed with annular from bottom to up between support baseboard and bearing housing base-plate
Pumping chamber, flange；The annular pumping chamber is that cover board, inner sleeve insertion support are arranged above inner sleeve by inner sleeve is arranged in housing
It is formed in bottom plate vestibule；Water outlet, the water outlet inner cavity and annular pumping chamber phase are provided in the housing outside cylinder
It is logical.
The flange and bearing housing base-plate is disconnected relationship.
The cover board setting is fixedly connected below flange with inner sleeve and housing.
The bearing rib and annular pumping chamber, water outlet, housing is disconnected relationship.
The inner sleeve (9), housing (6), cover board (3), water outlet (8), support baseboard (7) are by High-temperature resistant alloy material
It is made.
Beneficial effects of the present invention；Compared with traditional structure:
1. pump for liquid salts effluent seat in the prior art pumps effluent seat using core, bulky, raw material are wasted, due to pumped (conveying) medium
Influence, surrounding components are easily-deformable, reduce service life；The present invention is due defeated by design calculating pump for liquid salts effluent seat
It send efficiency, reduces annular pumping chamber size, using the minimum cavity design scheme for ensuring maximum pump discharge within the unit time,
Independent annular pumping chamber sole body is formed, than traditional endless pumping chamber volume reducing 15-20%.Compared with conventional cavity design,
Keep the unit time in cavity minimum to the heat of external diffusion, annular pumping chamber is influenced also to drop by heat transmitting and heat radiation
It is low.The reduction that heat transmitting and caloradiance that surrounding components structure is subject to can be achieved, plays the role of thermal resistance, to reduce ring
Shape pumping chamber surrounding components are influenced by high-temperature liquid state fused-salt medium.
2. solve the problems, such as pump for liquid salts critical support component structural stability under the high temperature conditions, by by the ring of effluent seat
The form that shape pumping chamber is isolated with surrounding components structure, the change of surrounding components structure caused by controlling because of temperature factor
Shape, and the influence that the support member that contacts with annular pumping chamber is deformed by annular pumping chamber.
3. changing the water leak seat structure of pump for liquid salts, reduced zero around annular pumping chamber by the change of component structural
Modular construction due to temperature by being influenced, and the influence of heat transmitting and heat radiation, play to surrounding components structure every
The purpose for improving support construction operation stability is realized in the effect of heat, thermal resistance, and present invention saves raw material, is reduced costs,
Substantially prolong the service life of equipment.
Detailed description of the invention
