Abstract
The invention discloses a rotation shell type hydrogenation water-injection pump driven by a secondary steam turbine, comprising a rotation shell pump (1). The rotation shell pump (1) is driven by an adjustable-speed back pressure steam turbine (2), the steam turbine (2) is connected with the rotation shell pump (1) through a diaphragm coupling (4), and the steam turbine (2) and the rotation shell pump (1) are installed on a common base (3). The structure adopted by the invention can ensure normal and reliable operation of a gasoline hydrocracking water-injection pump assembly, the overhaul period of the assembly is prolonged, the operation cost and the overhaul cost of the assembly are saved, and thus, the production efficiency is increased.
Description
Technical field
The present invention relates to a kind ofly drive turbine-driven rotation shell type hydrogenation water injection pump, as hydrocracking water injection equipment in the large-scale oil refining apparatus based on secondary steam.
Background technique
For centrifugal pump, realize high-lift approach nothing more than two kinds, the one, multipolarity, the 2nd, speed up.For multipolarity, reach 100m as single-stage impeller lift, can be from reaching the requirement of 1800m with 18 impellers, but such pump has 18 impellers, 18 stators, 18 inter-stage covers and two cover machines envelope or the like, size is huge, complex structure, maintenance difficult, maintenance expenses height.For speed up, mainly adopt high speed pump, the rotating speed of pump will reach about 24000r/min, because there are very big disc friction in liquid and housing, the efficient of pump is lower, can only reach about 30%.In addition, multistage pump, high speed pump in use can bring problems such as vibrations, noise and fluctuation of service.
Summary of the invention
The invention provides a kind of simple in structure, efficient is high drives turbine-driven rotation shell type hydrogenation water injection pump based on secondary steam.
The problem that will solve required for the present invention realizes by the following technical solutions: comprise rotary case pump, it is characterized in that: rotary case pump adopts the back pressure steam turbine of variable-speed to drive, connect by diaphragm coupling between steam turbine and the rotary case pump, steam turbine and rotary case pump are installed on the common bed.
The said structure that the present invention adopts, adopt housing and liquid single-stage, the rotation shell type centrifugal pump of rotation synchronously, rotating speed is controlled at about 5000r/min, driving turbine by secondary steam drives, can guarantee gasoline hydrogenation cracking water injection pump unit normal reliable operation, prolonged the unit maintenance cycle, saved the operation cost and the recondition expense of unit, thereby improved manufacturing efficiency.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Accompanying drawing is depicted as structural representation of the present invention
Among the figure 1, rotary case pump 2, steam turbine 3, common bed 4, coupling
Embodiment
By accompanying drawing as can be known, should drive turbine-driven rotation shell type hydrogenation water injection pump based on secondary steam and comprise rotary case pump 1, rotary case pump 1 adopts the back pressure steam turbine 2 of variable-speed to drive, connect by diaphragm coupling 4 between steam turbine 2 and the rotary case pump 1, steam turbine 2 is installed on the common bed 3 with rotary case pump 1.Variable-speed back pressure steam turbine 2 is driven by discarded secondary steam, and steam turbine drives major diameter rotation shell type single stage centrifugal pump, as gasoline hydrogenation cracking water injection pump.
After the hydrogenation water injection pump is transformed into the rotation shell type single stage centrifugal pump, the problems such as vibrations, noise and fluctuation of service in multistage pump, the high speed pump using process have been eliminated.
Obviously, the above embodiment of the present invention only is for example of the present invention clearly is described, and is not to be qualification to embodiments of the present invention.For those of ordinary skill in the field, can also make other multi-form variation or changes on the basis of the above description.Here need not also can't give all mode of executions exhaustive, and these belong to conspicuous variation or the change that spirit of the present invention draws and still are among protection scope of the present invention.
Claims (1)
1. one kind drives turbine-driven rotation shell type hydrogenation water injection pump based on secondary steam, comprise rotary case pump, it is characterized in that: rotary case pump adopts the back pressure steam turbine of variable-speed to drive, connect by diaphragm coupling between steam turbine and the rotary case pump, steam turbine and rotary case pump are installed on the common bed.
