Petroleum pump device capable of precisely metering flow

Abstract

The invention discloses a petroleum pump device capable of precisely metering flow. The petroleum pump device capable of precisely metering flow is provided with a round-tube-shaped pump body, a piston is embedded in the inner wall of the pump body, an oil inlet one-way valve and an oil outlet one-way valve which are opposite in direction are arranged at the top end of the pump body side by side,the bottom end of the piston is connected with a crankshaft through a connecting rod, the two ends of the crankshaft are connected with an electric motor and an encoder correspondingly, the electric motor drives the crankshaft to rotate through a reducer casing, the piston is driven by the crankshaft to reciprocate in the pump body, petroleum is sucked in from the oil inlet one-way valve, and is extruded out from the oil outlet one-way valve, after one cycle is finished, the volume of the pump body is the size of the pumped petroleum, at the moment, the encoder precisely records the ring number of the crankshaft, the volume of the pumped-out petroleum can be calculated, the problem that an existing petroleum conveying pump is poor in functionality is solved, and the good practical value isachieved.

Description

technical field [0001] The invention relates to a petroleum pump, in particular to a petroleum pump device for accurately metering flow. Background technique [0002] Petroleum is one of the most important sources of power for modern industry. It is the blood of industry. Human beings cannot live without oil. However, oil reserves are widely distributed on the earth. People not only develop oil fields on land, but also Many drilling platforms have been built in the ocean to develop oil. The petroleum extracted in various places needs to be smelted. The petroleum refining industry is the industry that processes crude oil into various petroleum products through the petroleum refining process. Including petroleum refineries, petroleum refining research and design institutions, etc. [0003] During the storage and transportation of oil, it needs to be metered. Different from solid objects, the measurement of petroleum is mostly determined by volume, such as liters, gallons, b...

Problems solved by technology

[0004] The present invention proposes a petroleum pump device for accurately metering flow, which solves the problem of insufficient functionality of existing petroleum delivery pumps. A circular tube-shaped pump body is provided, and a piston is installed in the pump body. Two check valves with opposite directions are installed side by side. The piston reciprocates in the pump body driven by the crankshaft, sucking oil from one check valve and extruding it from the other check valve. After completing a cycle , the volume of the pump body is the volume of the pumped oil
