Abstract
The utility model relates to a vertical ship-used high-temperature double-screw cargo-oil pump assembly consisting of s double-screw pump positioned on a carriage, a connecting frame positioned on the deck and an electric motor positioned on the connecting frame. The pump assembly is characterized in that the double-screw pump is a vertical structure; the vertical double-screw pump is connected with the electric motor through a universal drive shaft coupling; the shaft head of the vertical double-screw pump is connected with the universal drive shaft coupling through a shaft joint; the top of the universal drive shaft coupling is connected with a cabin-partitioned device positioned on the connecting frame through the shaft joint; and the cabin-partitioned device is connected with the electric motor through the shaft joint. The utility model has the advantages that the problem that the ship requires an occupied space of the pump assembly is resolved; when the well-type pump assembly is installed, the power input shaft is ensured to be precisely aligned with the screw pump shaft, thus providing a convenience for the well-type pump assembly installment; the service life of the driving system and the pump assembly are extended; and the ship-delivered high-temperature mediums, such as the asphalt and the residual oil, are realized in the safe transportation.
Description
Technical field
The utility model belongs to volume type screw pump technical field, particularly relates to a kind of compact structure of shipping high temperature media, high temperature twin-screw cargo oil pump unit vertical peculiar to vessel in saving occupation of land space of being applicable to.
Background technique
Two screw pump is a kind of positive displacement pump, has been widely used in each industrial field such as oil, chemical industry and boats and ships at present.In shipping industry, in order to reduce the shipbuilding cost, improve the boats and ships utilization ratio, require to dwindle the occupation of land space of pump or pump group, it is bigger that common two screw pump takies the space of cabin, so can't adapt to; But in the two screw pump of conventional cast, there is not the heat tracing structure, therefore can not the transfer of highly viscous medium, especially in the lower zone of temperature, owing to there is not the heat tracing structure also to influence the working efficiency of pump; In addition because screw pump transmits motion and the moment of torsion between parallel or alternating axis in mechanical transmission, constantly move according to certain rules in the axle center of pump, form a kind of compound motion state, therefore when deep-wall type pump group is installed, the coupling that adopts the common mechanical transmission to use is connected with power input shaft can't guarantee power input shaft and the high-precision centering of screw rod pump shaft, must adopt the coupling with universal transmission agency to satisfy and use job requirements.
Summary of the invention
The utility model provides a kind of compact structure of shipping high temperature media, high temperature twin-screw cargo oil pump unit vertical peculiar to vessel in saving occupation of land space of being applicable to for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
Vertical high temperature twin-screw cargo oil pump unit peculiar to vessel, be included in and be fixed with two screw pump on the lower supporter, be installed in link press span and the motor that is installed on the link press span on the boat deck, it is characterized in that: described two screw pump is a vertical structure, this Vertical Twin pump connects motor by universal driving linked shaft joint, the spindle nose of Vertical Twin pump connects universal driving linked shaft joint by coupling, be connected with the separation device that is packed on the link press span in universal driving linked shaft joint upper end by coupling, the separation device connects motor by coupling.
The utility model can also adopt following technical measures:
Be provided with heating chamber in the middle of in the described Vertical Twin pump, respectively there is a cooling chamber heating chamber both sides, and heating chamber and cooling chamber form the outlet of a cooling chamber import and a cooling chamber by pipeline connection.
Advantage and the good effect that the utlity model has are: because two screw pump of the present utility model adopts vertical structure, solved boats and ships the pump group is required to take up an area of the little problem in space; Between two screw pump and motor, adopted universal driving linked shaft joint to be connected, guaranteed the deep-wall type pump group highi degree of accuracy centering of power input shaft and screw rod pump shaft when mounted, not only the installation for deep-wall type pump group provides convenience, also can prolong the working life of transmission system and pump group simultaneously; The interior centre of two screw pump is provided with heating chamber and the cooling chamber by pipeline connection, can realize the safe transport of shipping high temperature media such as pitch or residual oil.
