[0002] The transformer oil pump is a crucial component of a transformer, primarily used to circulate transformer oil to various parts to ensure the transformer's normal operation. The working principle of the transformer oil pump involves an electric motor driving the pump to rotate, generating pressure and flow rate to draw transformer oil from the low-pressure area to the high-pressure area, thus achieving oil circulation.
[0003] A transformer oil pump mainly consists of an electric motor, pump body, impeller, bearings, and seals. The electric motor is the power source, driving the pump body and impeller to rotate. The pump body is the main load-bearing component; its internal cavity draws in transformer oil and pumps it out through the pump's rotation. Due to limited installation space in transformers, existing transformer oil pumps cannot adjust their mounting mechanisms according to the transformer's installation location, making installation difficult.
[0004] Therefore, a large transformer oil pump that is easy to fix is proposed here. Utility Model Content
