Oil delivery pump with sealing and tightening functions after butt joint for oil equipment

Abstract

The invention discloses an oil delivery pump with a sealing and tightening function after butt joint for oil equipment, and relates to the technical field of oil delivery pumps for oil equipment, the oil delivery pump comprises a pump body and a sealing and tightening assembly, a thermal insulation layer is fixed to the inner side of the pump body, and a flowing inner cavity is formed in the middle of the interior of the pump body; a liquid inlet and a liquid outlet are distributed in the two sides of the flowing inner cavity, fixing pipes are fixed to the outer sides of the liquid inlet and the liquid outlet, butt joint pipes are fixed to the outer sides of the fixing pipes, inner pipes are integrally arranged in the butt joint pipes, and the sealing tightening assemblies are arranged between the butt joint pipes and the inner pipes. An external pipe is installed on one side of the butt joint pipe, and a locking bolt penetrates through the butt joint pipe and the external pipe. According to the oil delivery pump with the sealing and tightening function after butt joint for the oil equipment, the external pipe and the butt joint pipe can be connected in a sealed mode, elastically tightened and locked and fixed, so that oil is prevented from leaking out of the joint, the oil can be filtered, impurity removal and pollution discharge can be conducted, and functionality is good.

Description

technical field [0001] The invention relates to the technical field of an oil delivery pump for oil equipment, in particular to an oil delivery pump with the function of sealing and tightening after docking. Background technique [0002] Oil equipment is a special equipment and special tool used for oil storage, transportation, filling and technical support in oil support. In the process of using the oil equipment, the oil needs to be pumped by the oil pump. The function of the fuel pump is to ensure that the diesel oil circulates in the low-pressure oil circuit, and supply sufficient quantity and certain pressure of fuel to the fuel injection pump. The fuel delivery volume should be 3-4 times the maximum fuel injection volume at full load. Oil transfer pumps are divided into gear oil transfer pumps, diaphragm oil transfer pumps, plunger oil transfer pumps, pipeline oil transfer pumps and so on. [0003] The existing oil pump for oil equipment cannot seal and tighten the c...

Problems solved by technology

[0003] During the use of the existing oil pump for oil equipment, when it is docked with the external pipe of the oil equipment, the joint cannot be sealed and tightened, and oil leakage is prone to occur. Therefore, we propose an oil equipment Use an oil transfer pump with the function of tightening the seal after docking
