Crane tube loading metering system

Abstract

The invention relates to a crane tube loading metering system. The crane tube loading metering system comprises a vertical tube, an oil pump, a flow meter and a controller, and further comprises a measuring rod vertically arranged on the periphery of the vertical tube, a feeler lever arranged on the measuring rod in a sleeving mode, an electronic bin arranged at the top of the measuring rod and afloater, wherein a small magnet close to the measuring rod is arranged in the feeler lever, and the feeler lever can freely move up and down along the measuring rod; and the floater comprises a floating switch arranged at the bottom end of the measuring rod and a protective shell arranged on the periphery of the floating switch and the periphery of the bottom of the measuring rod in a covering mode, and the protective shell can float on the oil surface and cannot fall off from the bottom of the measuring rod. According to the crane tube loading metering system, errors caused by different tanktruck heights can be eliminated, the flow meter or manual control can be replaced, start-stop control over the oil pump is achieved, and control is more accurate.

Description

technical field [0001] The invention belongs to the technical field of liquid metering and loading, and in particular relates to a crane pipe loading metering system. Background technique [0002] Liquid materials are ubiquitous in the petrochemical industry. In the loading metering station, in order to meet the normal operation of the loading system, it is necessary to measure and adjust the flow of oil products; common oil metering methods include rail scale weighing and truck scale weighing , ruler measurement or flowmeter measurement, the weight of the vehicle needs to be weighed before loading, and then the weight of the heavy vehicle is weighed after loading. The weight of the heavy vehicle minus the weight of the empty vehicle is the weight of the oil product; The measurement is to measure the oil level with a measuring ruler after loading, and calculate the weight of the loaded oil according to the density of the oil. The above two measurement processes are cumbersom...
