Cautions for Use of Tanker Flowmeters (2)

Xiagong Chu wins refueling vehicles also known as: tank cars, oil tankers, tankers, oil trucks. Mainly include: Dongfeng Freka Tanker, Dongfeng Tianjin Refueler, Dongfeng Dooligo Tanker, Dongfeng Tianlong Qianyihouba 8 Tanker, Dongfeng 145 Tanker, Dongfeng 153 Tanker, Futian Xiaocayou Tanker, Futian Auman top four after eight tanker, Liberated J6 tanker, Shaanxi Auto Delong tanker, rear Double Bridge tanker, front four rear eight tanker, semi-tank tanker, etc. Wait. Oil tankers (oil tankers) are mainly used for the transportation and storage of petroleum derivatives (gasoline, diesel, crude oil, lubricating oil, coal tar, etc.).
In the process of using the oil tanker, there are many places to pay attention to. Today, the technical staff of the XCMG Chu Sheng Technical Department talks about the use of the flow meter of the oil tanker.
First, in a piping system with a flow meter, it is necessary to avoid generating or entering air, otherwise it will cause inaccurate metering. Therefore, the flowmeter should be used when the entire system is full of oil. Flow meter system precision instrument, the measurement room, the detection element gap is very small. Therefore, large particles and other impurities must not enter the flowmeter. It is forbidden to use the flowmeter without a filter.
Second, the flowmeter must not exceed the specified flow rate and pressure range. In continuous operation, the flow in the pipeline should not exceed 600-800L/min. The maximum flow rate is regulated in order to accommodate the sudden increase in flow and other conditions. Use it for a short time or in a moment. The flowmeter has a zero-return knob on the meter head. Before the work, check whether the count and the pointer are back to zero. After each refueling operation, turn the knob clockwise to return the hands and one count to zero. It is forbidden to move the pointer when the flowmeter is working.
Third, the flowmeter should avoid working under pressure surges and overload surges. Therefore, it is necessary to switch the fuel ball valve and the refueling gun smoothly and slowly during use, and prevent the measured medium from flowing back into the flow meter. When the flow meter is installed, the shaft of the waist wheel should be installed horizontally, and the flow direction through the flow meter should be consistent with the direction indicated by the arrow on the housing; the flow meter should not be subjected to expansion, contraction, deformation and vibration of the pipeline.
