A radial impeller is installed in a shell body of the pipeline pump, a flow passage with a sawtooth structure enables an inlet and an outlet of the pipeline pump to be coaxial, the circulating and cooling efficiency is high, the installation is convenient, both the pipeline pump shell and a motor shell adopt high intensity aluminum alloy for casting, a motor end cover with a spoke structure enables a stator and a rotor of the motor to be completely immerged in flowing transformer oil, which not only guarantees cooling of the motor stator, but also guarantees lubrication of a bearing, the service life of an oil pump motor can be intensified, the pipeline pump which adopts the structure can be convenient for the selection of motor parameters and impeller size in design, and ideal water power performance parameter demands can be satisfied.
Description
Technical field
The utility model relates to a kind of transformer pipeline mounted pump that is used for forced oil-circulation cooling usefulness such as high-power transformer, reactor.
Background technique
The transformer forced oil-circulation adopts the radial impeller centrifugal pump mostly with oil pump at present, and oil pump case all adopts iron structure, cast steel structure and welded-steel plate construction are arranged, so weight is big.With the passing of time steel structure oil pump surface is prone to rusty stain, discontented toe ring guaranteed request.Though the Oil pump electrical machinery winding is immersed in the oil, transformer oil herein is that the several apertures from the electric motor end cap flow into, the little oil in hole mobile bad, so the cooling effect of motor stator winding is bad.The inlet of existing in addition radial impeller centrifugal pump with export into 90 °, so the installation difficulty of pipeline is big.
Summary of the invention
The purpose of this utility model provides a kind of in light weight, installs easily, and hydraulic performance is good, the operational reliability height, and the life-span is long is used for the pipeline mounted pump that the high-power transformer forced oil-circulation is used.
The utility model comprises the pipeline mounted pump housing, coupled electric machine casing, junction box body, electric motor end cap is the spoke architecture of tape spool bearing, in the electric machine casing Y type motor stator and rotor, in the pipeline mounted pump housing radial impeller is housed, the runner of band saw toothing makes the import of pipeline mounted pump coaxial with outlet, and pipeline mounted pump housing and electric machine casing all adopt the high tensile aluminium alloy cast; The steel blanking cover of tape spool bearing adopts interference fit to connect with electric machine casing.
The utility model is because housing all adopts the high tensile aluminium alloy cast, and weight is very light; The steel blanking cover of tape spool bearing adopts interference fit to connect with housing, can guarantee the sealing of mating part, and the rigidity of bearing support can guarantee the reliable operation of motor; The electric motor end cap of spoke architecture is immersed in the mobile transformer oil motor stator and rotor fully, has both guaranteed the cooling of motor stator, has guaranteed the lubricated of bearing again, and strengthened the working life of Oil pump electrical machinery; The coaxial pipeline mounted pump of inlet/outlet adopts radial impeller, and circulation cooling effectiveness height is easy for installation, and desirable hydraulic performance parameter request is satisfied in the selection of the parameter of electric machine and impeller size when adopting the pipeline mounted pump of this structure conveniently to design.
Description of drawings
Fig. 1 is the utility model structural representation.
1 is impeller among the figure, and 2 is electric motor end cap, and 3 is Y type motor stator, and 4 is rotor, and 5 is the steel blanking cover, and 6 is electric machine casing, and 7 is the pipeline mounted pump housing, and 8 is junction box body.
Embodiment
As shown in Figure 1, the utility model comprises pipeline mounted pump housing 7, coupled electric machine casing 6, junction box body 8, electric motor end cap 2 is the spoke architecture of tape spool bearing, is Y type motor stator 3, rotor 4 in the electric machine casing, radial impeller 1 is housed in the pipeline mounted pump housing, the runner of band saw toothing makes the import of pipeline mounted pump coaxial with outlet, and circulation cooling effectiveness height is easy for installation; Pipeline mounted pump housing and electric machine casing all adopt the high tensile aluminium alloy cast, the steel blanking cover 5 of tape spool bearing adopts interference fit to connect with electric machine casing 6, the electric motor end cap of spoke architecture can conveniently flow in the electric machine casing transformer oil, the motor stator and rotor are immersed in the mobile transformer oil fully, both guaranteed the cooling of motor stator, guaranteed the lubricated of bearing again, strengthened the working life of Oil pump electrical machinery.
