The function of the steam-water separator is to remove the moisture in the steam and provide steam that keeps the drying coefficient constant. The baffle type steam separator has high efficiency. During its working process, the water droplets are mainly blocked by the baffle, and the low-speed steam also ensures that the water droplets will not re-enter the gas flowmeter. A steam trap at the bottom of the separator will allow the water to exit the separator quickly. Use of environmental issues. Especially for the sensor part installed in the ground well, due to the high ambient humidity, the circuit board is damp. Through corresponding technical improvement measures, some sensors with high ambient humidity have been re-separated from the probe part and the conversion part. Type sensor, so the working environment is improved, and the table runs well. If there are two 90° elbows on different planes upstream of the sensor installation point, then: the upstream straight pipe section ≥ 40D, and the downstream straight pipe section ≥ 5D. The regulating valve should be installed beyond 5D downstream of the sensor. If it must be installed upstream of the sensor, the straight pipe section upstream of the sensor should not be less than 50D, and the downstream should not be less than 5D. The piping upstream and downstream of the installation point should be concentric with the sensor, and the coaxial deviation should not be less than 0.5DN. Water hammer can cause damage to the gas flow meter, and the water separator can prevent this phenomenon. There are many faults in this part, including: there is a disconnection on the circuit board of the primary instrument, some digits of the range setting are displayed badly, and some digits of the K coefficient setting are displayed badly, making it impossible to determine the range setting and the K coefficient setting. By fixing the corresponding glitches, the problem is resolved. Quad line connection problem. There is always no indication in the circuit due to the failure of the secondary instrument flat shaft cable. Due to the long-term operation and the influence of dust, the flat-axis cable is faulty. The problem can be solved by cleaning or replacing the flat-axis wire. Because the secondary instrument shows that the fixing screw of the meter head coil is loose, causing the meter head to sink, the friction between the pointer and the case is large, and the movement is not effective. Adjust the meter head and fix it again. Choose the installation site and environment reasonably. Avoid strong power equipment, high-frequency equipment, and strong power switching equipment: avoid the influence of high-temperature heat sources and radiation sources, avoid places with strong vibrations and strong corrosion environments, etc., and at the same time consider the convenience of installation and maintenance. 2. There must be enough straight pipe sections upstream and downstream. If there are two 90° elbows on the same plane upstream of the sensor installation point, then: the upstream straight pipe section ≥ 25D, and the downstream straight pipe section ≥ 5D. Some circuits seem to be well connected on the surface. Check carefully. Some connectors are actually loose and the circuit is interrupted; interruption. The connection problem between the secondary meter and the subsequent meter. Due to the problem of the follow-up instrument or the maintenance of the follow-up instrument, the mA output circuit of the secondary instrument is interrupted, especially for the follow-up recorder. When the recorder is damaged for a long time and cannot be repaired, it must be short-circuited to the secondary instrument. output.
Given the important role played by in ensuring proper functioning of tuning fork liquid density meter, every individual must take an interest towards improving rosemount vortex flow meter.
