A precise weighing system for floor scales

Abstract

A precision weighing system for ground scales includes a fixed weighing system beneath a square tank. The tank has an inlet and an outlet. The weighing system comprises a small switch, an AC contactor, a microcomputer, a power strip, weighing sensors, and a display. The small switch connects to 220V AC mains power and is connected to the AC contactor and the microcomputer. The AC contactor is connected to the microcomputer, and the power strip is connected to the weighing sensors and the display. Pumped oil enters through the inlet and is preheated by a boiler truck to prevent the crude oil from solidifying due to low temperatures. The materials inside the small weighing system are deformed by compression, causing changes in the resistance strain gauges inside the sensors. This converts gravity into an electrical signal, measuring the weight, which is then displayed on the screen. The small switch connects to the AC contactor and the microcomputer, and the AC contactor connects to the power strip. Under the control of the microcomputer, the display and sensors are automatically charged. This system improves the accuracy of oil well production data, providing fundamental data for calculating various subsequent oilfield data and evaluating the effectiveness of related oilfield development measures.

Description

Technical Field

[0001] This utility model belongs to the field of oil well construction technology, specifically relating to a precision weighing system for ground scales. Background Technology

[0002] Low production and measurement issues have long plagued grassroots staff in the eastern oilfields. The Xinyao Oil Production Team of the Nanniwan Oilfield uses various oil storage tanks, including underground tanks, semi-underground tanks, four-sided metering tanks, and eight-sided surface tanks. Traditionally, measurement is done by inserting a wooden stick into the tank to gauge the crude oil depth, then removing the stick and measuring with a steel tape measure. This method is prone to oil spillage, polluting the environment, wasting resources, and introducing measurement errors. Accurate oil well metering is crucial, providing real, accurate, and effective first-hand data for subsequent secondary development, water injection effect evaluation, and dynamic analysis. Therefore, a precision metering system using a ground scale was designed to accurately measure the dynamic production capacity of oil wells. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a precise weighing system for ground scales, improve the accuracy of oil well production data, and provide basic data for the calculation of various data in the next step of oilfield development and the evaluation of the effects of relevant oilfield development measures.

[0006] The square tank (1) is equipped with a preheating coil (5), which is heated by a boiler truck.

[0007] The beneficial effects of this utility model are:

[0013] The present invention will be further described below with reference to the accompanying drawings and working principle.

[0014] like Figure 1 , 2 As shown, a precise weighing system for floor scales includes a square tank (1), characterized in that a floor scale system (2) is fixed below the square tank (1); the square tank (1) is provided with an inlet (3) and an outlet (4); the floor scale system (2) consists of a small switch (6), an AC contactor (7), a microcomputer (8), a power strip (9), a floor scale sensor (10), and a display (11). The small switch (6) is connected to 220V AC mains power and is connected to the AC contactor (7) and the microcomputer (8); the AC contactor (7) is connected to the microcomputer (8); the AC contactor (7) is connected to the power strip (9); the power strip (9) is connected to the floor scale sensor (10) and the display (11).

[0015] The square tank (1) is equipped with a preheating coil (5), which is heated by a boiler truck.

[0016] Implementation:

[0017] 1. A 1000mm x 1000mm square concrete base plate is used as the base, ensuring the surface is level. When a square can is placed on the smaller base, the material will be compressed and deformed. This deformation causes a change in the resistance strain gauge inside the sensor, which in turn converts gravity into an electrical signal output. This achieves the process of force-to-electricity conversion.

[0018] Second, the display screen data receiving section has a time-controlled charging function, which can charge the display screen and sensors simultaneously, with a single charging time of no less than 5 hours.

[0019] The working principle is as follows: the oil pumped up enters through the inlet and is heated by the boiler truck to the preheating coil, preventing the crude oil entering the tank from solidifying due to low temperature. The materials inside the small weighing scale are squeezed and deformed, causing the resistance strain gauge inside the sensor to change, which in turn converts gravity into an electrical signal output, measures the weight, and displays it on the display. The small switch is connected to the mains power, and the small switch is connected to the AC contactor and the microcomputer. The AC contactor is connected to the power strip, and under the control of the microcomputer, it works with the AC contactor to charge the display screen and the sensor.
