The gas turbine flowmeter is a high-precision testing instrument. Pay more attention to the aspects of transportation, loading, unloading, and storage. Minor errors are likely to cause counterfeiting of equipment or data errors that endanger the equipment. In the specific application, the seal must be completely removed, and the logo must be removed. How to check the gas turbine according to simple methods such as anger to distinguish the gloss and flexibility. Before installation, especially when new natural gas pipelines are in use, they should be completely cleaned up in advance to clean up metal hose installation and connection residues, rust, etc. If the pipeline contains residues, it will not only endanger the flow rate measurement, but also continue to cause the total flow rate of the pipeline to collapse. After the pipeline is cleaned, a static pressure test should be carried out. Before and after the experiment, the solid state in the pipeline must be clean and tidy, and no residue, otherwise the gas turbine flowmeter will be destroyed. If the test cannot be omitted; the gas turbine flowmeter should be replaced with another component; and re-check during the test period to ensure that there is no liquid residue in the pipeline system software.
Plus a gas turbine flow meter. If the system software stipulates that the flow meter has its own refrigeration system, it is stipulated to ensure that the nozzle of the subject active component faces upwards during the entire process of application and installation. In addition, before use, check the inflow from the side of the flowmeter from top to bottom. Under all conditions, the pipe should be placed on the upper side of the hole of the opposite gas turbine flowmeter, and the pipe diameter should not be less than or equal to the three-dimensional N. In addition, the middle pipeline or elbow should be placed symmetrically with the middle and downstream of the above pipeline, and the total width should not be less than or equal to 3DN. Before the gas turbine flowmeter is installed, the opening of the gas slowing pressure pipe and the shunt pipe should be less than 30° to ensure low gas transportation and maintenance costs. The bypass valve tube is set on the flow meter. When operating the gas turbine, the working pressure speed of the phase should be kept slow. If the working pressure is too fast, the relevant index values of the turbine blades and the turbine flowmeter will be damaged.
When it is necessary to weld the gas turbine flowmeter installation pipe by electric welding, the flowmeter must be basically cleaned before electric welding. The gas turbine flowmeter is likely to be destroyed by the high temperature caused by the welding quality of electric welding, resulting in unavailability and other adverse effects. During operation and installation, it should be noted that the fluidity method of the gas in the pipeline is consistent with the orientation marked on the flowmeter casing. If it is inconsistent, please download it again for free immediately, otherwise the turbine blades of the flowmeter will turn over. The gas-gathering station pipeline should be kept vibration-free and not mixed with residues in the gas to ensure the cleanliness of the gas. If the gas and debris are mixed together, the increase may be destroyed. If the cleanliness level of liquid transportation will not be manipulated, the gas filter device should be placed before the gas flowmeter. When installing outdoor gas pipelines and adding additional gas turbine flow meters, the corresponding wind-proof, cold-proof and warm-keeping equipment should be set according to the specific conditions. Generally speaking, the specific scope of application should be in the middle of 20 to 80 percent. The gas turbine flowmeter can be loaded to a certain level in a short period of time, but the specific load cannot exceed 20% of the larger flowmeter, the load time should be within 0.5h, and the rubber seal should be applied according to the design plan.
