是计量流经管道内液体流量总和的容积式流量计，我公司的流量计具有测量精度高,受液体粘度影响小，表前不需要安装直管段,，广泛用于石油、化工、医药卫生等油类及高粘度介质的累积流量测量。 Oval gear flowmeter is a volumetric flowmeter that measures the sum of the liquid flow in the pipeline. Our company's flowmeter has high measurement accuracy and is not affected by the viscosity of the liquid. There is no need to install a straight pipe section before the table. It is widely used in petroleum, chemical, Cumulative flow measurement of oils and high-viscosity media such as medicine and health.
正确安装后的椭圆齿轮流量计，使用时可保证足够的精度，是一种较为准确的流量计量仪表。 The elliptical gear flowmeter after the elliptical gear flowmeter is correctly installed can ensure sufficient accuracy when used, and is a more accurate flowmeter. However, if the flow rate of the measured medium is too small during use, the effect of the leakage error of the instrument will be prominent, and sufficient measurement accuracy cannot be guaranteed. Secondly, when using an elliptical gear flowmeter, pay attention to the temperature of the measured medium must not be too high, otherwise it will not only increase the measurement error, but also may cause the gear to jam. After long-term use, the gears inside the oval gear flowmeter will be corroded and worn, which will affect the measurement accuracy. Therefore, it is necessary to pay attention to observation and take it apart regularly for inspection. If conditions permit, it is better to perform calibration regularly. The flow measurement has nothing to do with the flow state of the fluid. This is because the elliptical gear flowmeter relies on the pressure head of the measured medium to push the ellipse gear to rotate for measurement. The elliptical gear flowmeter has high measurement accuracy and is suitable for measuring the flow of high-viscosity media, but it is not suitable for fluids containing solid particles. Clean the pipes before installing the flowmeter. If the liquid contains solid particles, a filter must be installed upstream of the pipeline; if there is gas, an exhaust device should be installed. During installation, the elliptical gear rotation axis of the flow meter should be parallel to the ground.
由于属于比较精密的仪器，容易出问题的地方大多是在内部，因为内部有齿轮工作，齿轮对流动液体的清洁度有要求。 Oval gear flowmeters are relatively sophisticated instruments, and most of the problem-prone parts are inside, because there are gears inside, and the gears have requirements for the cleanliness of flowing liquids. It is easy to be stuck, and there are problems such as no display or large display fluctuation. The common faults and processing methods are as follows: 1. The degree on the display remains at a certain value. The fault processing method: first determine whether the signal feedback system is faulty. Turn off the power and check whether the signal feedback loop is on and whether the voltage is normal. If the fault is not removed, you can clean the pipes and filters. If the filter or pipeline is damaged, the flow meter can be disassembled and inspected to remove impurities. When disassembling, remember the entry points of the upper and lower gears, and install them as they are. 2. The degree is unstable on the display, and the troubleshooting method is to check whether the flow rate display system is vibrated; or turn the gear of the flow meter by hand to see if the display reading has changed. Generate a limited feedback signal. 3. When the flow is small, the error is relatively large, and the troubleshooting method may be that the gear sleeve is worn or corroded by the medium, and the flowmeter casing is deformed. At this time, you can generally hear a clicking noise when the flowmeter is working. 4. The error is very large or small. Actually, the troubleshooting method is because the fluid may contain gas, or the zero signal voltage is abnormal. Need to stop the operation to recalibrate the flowmeter. 5. There is a leak in the liquid. Fault handling method: If there is a leak, the fault must be caused by the aging of the seal ring. Just replace the seal ring.
