Abstract
The utility model relates to an axial flowing transformer oil pump, which belongs to an oil pump used in the large-medium transformer cooling system. An impeller 1 is fixed to an electric machine impeller 2. The electric machine and an outlet box (3) are fixed to a chassis 4. The utility model has the advantages of automatic running system, a breakthrough in the reliability level, excellent heat rejection, longer running service life, a reasonable structure and a wide range of application. This product can be used to substitute the imported products, which fills up the blank at home.
Description
Technical field
The utility model belongs to big-and-middle-sized transformer cooling system oil pump.
Background technique
At present, both at home and abroad the oil pump that uses of power grid construction is the conventional centrifugal transformer oil pump, deficiency such as exist that noise is higher, reliability is lower, environmental protection is relatively poor and automatic control level is lower.
Summary of the invention
The utility model provides a kind of axial flow transformer oil pump, solved that the noise that prior art exists is higher, reliability is lower, environmental protection is relatively poor and deficiency such as automatic control level is lower.The concrete technological scheme that the utility model is taked is: impeller 1 fixedly connected motor 2, this motor and outlet box 3 are fixed on the casing 4.
Advantage of the present utility model is: implement telecontrol, make operation automation, the reliability level of transformer oil pump that breakthrough raising arranged; The design of employing shielding, good heat dissipation effect, service life is long, thereby has improved the reliability engineering level of system; Rational in infrastructure, applied range; Can the import substitution product, filled up domestic blank.
