In the petroleum storage industry, centrifugal oil transfer pumps need to use mechanical seals of the crude oil flushing drive end and the non-drive end from flushing pipelines to take away heat generated by high-speed rotation friction of the centrifugal oil transfer pumps, and the centrifugal oil transfer pumps are prevented from being thrown out due to overhigh temperature of the mechanical seals. The mechanical seal leaks crude oil to the outside of the pump body at a leakage speed of less than 5mL/h, and the crude oil is collected by a leakage elbow and conveyed into a leakage tank and finally discharged into a dirty oil tank; when the high viscosity oil or the high condensation oil is transported in winter, because the temperature is extremely low and the flow rate of leaked crude oil is very low, the crude oil at the bent pipe of the leakage bent pipe below the mechanical seal or in front of and behind the leakage tank is easy to solidify and accumulate to block the pipeline, so that the leaked crude oil is emitted from the mechanical seal or the leakage tank opening.

At present, the conventional solution of the leakage elbow blockage is to pour hot water into a machine seal cavity, a leakage tank or the outside of a blocked pipeline, reduce viscosity of crude oil under the action of high temperature and improve fluidity, and then open a machine seal cover to repeatedly plug and pull the leakage elbow from an inlet and an outlet of the leakage elbow by using a thin iron wire until the blockage is removed.
