Embodiment

[0030] Embodiment: a kind of energy-saving electric pump (see figure 1 ), characterized in that it includes a base 1, a check valve 2, a suction port 3, a pump 4, a guide bearing seat 5, an inner oil suction cover 6, an outer oil suction cover 7, a motor 8, a flange body 9 and a joint 10; The base 1 has the inlet I A of the main channel and the inlet IIB of the bypass large flow channel; the inlet I A of the main channel corresponds to the inner space of the inner oil suction cover 6, and the inlet IIB of the bypass large channel corresponds to the inner oil suction cover 6. Between the cover 6 and the outer oil suction cover 7, an annular space is formed correspondingly; a suction inlet 3 is installed above the inlet 1 A of the main channel; a pump 4 is installed on the suction inlet 3; the above pump 4 is connected with the motor through the guide bearing seat 5 8 connection; the upper part of the motor 8 is connected to the joint 10 through the flange body 9; a check valve...

Abstract

The invention relates to an energy-saving electric pump, which is characterized in that the energy-saving electric pump comprises a base, a check valve, a suction inlet, a pump, a guide bearing seat, an inner oil suction hood, an outer oil suction hood, a motor, a flange body and a joint; the inlet of a main flow passage, the suction inlet, the pump, the flow passage of the guide bearing seat, a flow passage between the shell of the motor and the inner wall of the inner oil suction hood, the flow passage of the flange body and the inner flow passage of the joint form the main flow passage; and the inlet of a bypass large flow passage, a flow passage formed by the check valve and the base, an annular flow passage formed between the inner oil suction hood and the outer oil suction hood and the side flow passage of the joint form the bypass large flow passage. The working method of the energy-saving electric pump is characterized in that: during unloading, oil firstly enters the main flow passage of the energy-saving electric pump, then the check valve is opened, the oil enters the bypass large flow passage and the two flow passages deliver the oil; and during loading, a filling accessory opens the check valve and the two flow passages deliver the oil. The energy-saving electric pump has the advantage that the air resistance in an oil delivery pipe is thoroughly eliminated because a suction system is changed to work in a positive-pressure oil delivery mode instead of the original negative-pressure oil suction mode.

Description

(1) Technical field: [0001] The present invention relates to an electric pump for conveying oil, in particular to an electric pump which submerges in the oil and runs in the oil to save energy. (two) background technology: [0002] At present, the oil products that are generally sold and used in the market are usually transported by tanker trains and special tankers for water and land transportation. After the oil products are transported to the oil depot or oil terminal, a special oil delivery system for loading and unloading oil products is equipped in the loading and unloading operation area. The conventional oil transportation system uses movable oil pipelines, that is, loading and unloading crane pipes, which are inserted into these movable oil tanks or storage tanks to suck oil, and then pass through fixed oil collection pipelines and pipeline pumping stations and other facilities. , to transport the oil to the fixed oil storage tank in the oil depot (see attached fi...
