Refueling system convenient to use on construction site and taking weight as metering unit

Abstract

The invention discloses a refueling system convenient to use on a construction site and taking weight as a metering unit. The refueling system comprises a hardware part and a software part, the hardware part comprises a shell, an oil pump is arranged in the shell, an inlet of the oil pump is connected to an oil tank through an oil pipeline, an outlet of the oil pump is connected to an oil gun through a refueling pipe, and an oil gun switch is arranged on the oil gun and is connected to an oil gun state control module. According to the refueling system, a weighing tank is arranged on the oil pump and an oil gun oil pipe of a refueling machine, an electronic scale is arranged under the weighing tank, so that the density of oil at the current temperature can be calculated by utilizing the weight and the volume of the weighing tank, the weight of refueling each time is further calculated by utilizing the density and the refueling volume fraction, so that the system is used for a construction site gas station to realize weight input and weight output of the oil, statistics and accounting of a management department are facilitated, meanwhile, errors caused by temperature can be reduced by utilizing the calculated actual density, and refueling is more accurate.

Description

technical field [0001] The invention belongs to the technical field of refueling equipment application, and in particular relates to a refueling system with weight as the unit of measurement that is convenient for construction sites. Background technique [0002] With the popularization of mechanization, the existing large-scale construction sites will be equipped with many heavy construction machinery during the construction process. In order to facilitate the refueling of heavy construction machinery vehicles, engineering contractors will choose to set up site gas stations in the construction area. During use, because the construction site is equipped with a weighbridge, the tanker tows the purchased oil to the gas station on the construction site, and the weighbridge weighs the tanker before and after unloading the oil, and the company finances to pay the oil delivery company through the weight of the oil. After the purchase of oil products, the existing tankers mostly us...

AI Technical Summary

Problems solved by technology

[0003] 1. It is inconvenient for the oil depot management department to make statistics on the incoming and outgoing oil products, and cannot directly obtain the remaining oil volume, which leads to untimely purchase of oil products

[0004] 2. The conversion error between volume calculation and weight calculation leads to a large error in the data of oil in and out of each tank, and there is an imbalance between the in and out accounts

[0005] 3. The existing fuel dispensers measured by volume are greatly affected by temperature, resulting in large differences in refueling volume at different times. For large engineering vehicles, the difference will be more obvious due to the large amount of refueling, which will lead to relatively large settlements. big problem
