是工业流量测量中应用较多的流量测量仪表，广泛应用于化工、制药、石油、轻工业和科研部门。 Glass rotor flowmeter is a flow measurement instrument that is widely used in industrial flow measurement. It is widely used in chemical, pharmaceutical, petroleum, light industry and scientific research departments. Although there are many products for measuring flow, because of the advantages of simple structure, convenient operation, and low price, glass rotor flowmeters are welcomed by users. Especially small and medium-sized enterprises require low degree of automation. The leading product of traffic. I have some suggestions on how to use and maintain the glass rotor flowmeter correctly: 1. When getting the glass rotor flowmeter, first observe whether the glass tube in the glass rotor flowmeter is intact, because the glass tube is very easy to break. The second is to remove the fixed part of the rotor and gently tilt it to see if the rotor can slide up and down freely. If you cannot slide freely, you need to gently vibrate the support plate so that it can generally slide. If you can no longer slide, you need to ask a professional technician to disassemble the machine. 2. When installing on the pipeline, first check whether the upstream and downstream pipelines are in a straight line. If it is not on a straight line, it will not only affect the measurement accuracy of the meter, but also damage the meter. 3. The first two points must be correct before they can be used. The operator should read the manual in detail before using it. When opening the valve, you must open it slowly. If it is estimated that the flow can float the rotor and the rotor does not move upwards, immediately stop the valve and continue to tap the pipe, so that the rotor can rise slowly. Many operators have opened the valve too fast and just installed new equipment. The sudden opening of the valve caused damage to the glass tube in the glass rotor flowmeter. This should be brought to the attention of the user. 4. Safe use. Some operators like to remove the front cover for use. This is not allowed because the glass tube is easy to burst and the cover plays a protective role. Therefore, you cannot remove the cover and use it. 5. Please keep warm during winter use. If you do n’t use it at night, be sure to let out the residual liquid in the flowmeter, so as not to freeze the glass tube.
的安装:1.为便于在使用过程中更换零部件，流量计安装时应留有足够的维修空间。 Installation of glass rotor flowmeter : 1. In order to facilitate the replacement of parts and components during use, sufficient maintenance space should be left when the flowmeter is installed. 2. For inspection, repair, replacement of flow meter and cleaning pipeline, install bypass pipe if necessary. 3. The newly installed pipeline should be flushed when the flowmeter is installed. The flow meter should be installed vertically. 4. When the flowmeter is installed, the pipes connected to the flowmeter should be fixed firmly, so that the stress generated by the pipes is not transmitted to the spinal tube of the flowmeter. 5. If there is backflow in the pipeline, especially the action of water hammer to prevent damage to the flowmeter, a one-way check valve should be installed after the valve downstream of the flowmeter. 6. If the fluid to be measured contains large particles or stolen materials, a filter should be installed upstream of the flow meter as required. 7. If the measured fluid flow is pulsating flow, which causes the float to fluctuate abnormally, a buffer or custom device of appropriate size should be set upstream of the flow meter to eliminate the pulsation. 8. A valve should be installed upstream of the flow meter, and a flow regulating valve should be installed. 5 to 10 times the nominal diameter downstream of the flowmeter. 9. When the flow meter is installed in the pipeline, the minimum graduation value of the flow meter should be below
的使用:1、流量计使用时，应先缓慢开启上游阀门至全开，然后用流量计下游的调节阀调节流量。 Use of glass rotor flowmeter : 1. When using the flowmeter, slowly open the upstream valve to full open first, and then use the regulating valve downstream of the flowmeter to adjust the flow. When the flowmeter is stopped, the valve upstream of the flowmeter should be closed slowly, and then the flow regulating valve downstream of the flowmeter should be closed. 2. The flow meter must read the displayed value after the float is stable. Float reading position: The reading position is at the maximum diameter of the float. 3. Avoid sudden changes in the temperature and pressure of the fluid being tested. Prevent puncture tube from damaging people. 4. Clean contaminated tubes and floats in a timely manner. 5. The working diameter and sharp edge of the float should be recalibrated if damaged. 6. When the flowmeter needs to be disassembled, it should be familiar with its structure, especially when disassembling the gland and the bolts of the support plate, to apply even force to prevent the cone tube from being broken. 7. When the density, temperature, pressure and indexing state of the fluid passing through the flowmeter are different (ie standard state), the displayed value must be corrected. 8. The flowmeter in use should be checked regularly. If leakage is found, the flowmeter should be decompressed first, then the gland should be evenly tightened, and the gland should not be clamped too tightly.
