Abstract

The invention relates to an oil-gas separation circular arc type inside engaged gear combined oil pump which comprises a pump body (1), the bottom of the pump body (1) is provided with an oil suction hole (1.1) and an oil suction hole check valve (12); the lower part in the pump body (1) is provided with an oil inlet cavity (1.2); the middle in the pump body (1) is provided with an oil inlet chamber (1.3), an eccentric body (4), an oil outlet chamber (1.4) and an oil-gas separation chamber (14), wherein, the eccentric body (4) is internally provided with a combined pump spindle (6) which is provided with a circular arc type inside and outside gear set (5), the wall of a shell of the eccentric body (4) is provided with an eccentric body oil inlet (4.1) and an eccentric body oil outlet (4.2); the upper part in the pump body (1) is provided with an oil outlet channel (1.5); the top of the pump body (1) is provided with a pump cover (13), the top of which is provided with an oil outlet (13.1); the oil outlet channel (1.5) is internally provided with an oil-gas separation pipe (8); the lower part of the oil-gas separation chamber (14) is provided with an oil return float valve (15), and a gas bleeder (16) and a gas bleeding float valve (17) are arranged on the top of the pump cover (13) arranged above the oil-gas separation chamber (14). The combined oil pump has stronger oil-gas separation capability and compacter structure.

Description

(1) Technical field [0001] The invention relates to a light fuel oil delivery pump-an oil-gas separation arc type internal meshing gear combined oil pump. It belongs to the technical field of fuel oil delivery equipment. (2) Background technology [0002] In the prior art, the combined oil pump is one of the core components of the fuel oil delivery equipment commonly used in each gas station. For example, the oil and gas separation capacity of the combined oil pump used before is relatively low. The original structure adopts the volume of the gas-liquid separation chamber is large enough, so that the flow rate is reduced, and the gas and liquid are separated by the difference in the specific gravity of the liquid and the gas. The gas is discharged through the extrusion pipeline, and the liquid is sucked into the impeller through the return valve hole and then combined with the gas. Mix and circulate sequentially until the gas in the suction line is exhausted, then the pump...
