Turbine flowmeter is well known flowmeter, positive displacement flowmeters and Coriolis mass flowmeters are three types of repetitive accuracy the best products, and turbine flowmeter also has its own characteristics, such as simple structure, less machining parts , light weight, easy maintenance, large flow capacity and adaptability to high parameters. Changzhou Chengfeng's LWGY series turbine flow meter also draws on the advanced design of advanced flow meter technology at home and abroad, featuring high accuracy, good reproducibility, responsiveness, and ease of installation and maintenance. If it is equipped with a display instrument with special functions, it can also perform quantitative control, over-alarm, etc. It is an ideal instrument for flow measurement and energy saving. Turbine flowmeters have a lot of small problems in the installation and operation, but they must pay attention to these details to ensure the accuracy of the flowmeter. If you do not pay attention to many details, you will find it difficult to find the problem when you use it. Today, we have summarized the problems that are easily overlooked. We hope that it will attract everyone's attention. 1, the piping requirements: The inner diameter of the upstream and downstream piping of the turbine flow meter device point is the same as the inner diameter of the flow meter. 2. Requirements for straight section: The necessary degree of the flow meter is installed on the pipeline (the pipeline is inclined within 50 degrees). When the device is installed, the flow meter axis should be concentric with the pipeline axis, and the flow direction should be different. The length of the pipeline upstream of the flowmeter shall have a straight pipe section of not less than 2D. If the installation site permits, the upstream straight pipe section is 20D and the downstream is 5D. 3, the requirements of the bypass pipe: In order to ensure that the turbofan meter does not affect the normal operation of the medium during maintenance, the valve (cut-off valve) should be installed on the front and rear pipelines of the flowmeter, and a bypass pipeline should be provided. The flow control valve should be installed downstream of the flowmeter. When the flowmeter is used, the shutoff valve installed upstream must be fully opened to prevent the upstream local fluid from generating unstable flow. 4. Requests for the external environment: The flowmeter is best to be installed indoors. When it is necessary to install it outdoors, sunscreen, rain, and lightning protection measures must be adopted so as not to affect the service life. Requirements for impurities in the medium: In order to guarantee the service life of the turbine meter, a filter should be installed in front of the straight section of the flow meter. 5, in the selection requirements: The selection is within the regular flow range to avoid over-speed operation to ensure the desired accuracy and guarantee the normal service life. When the flowmeter is running, it is not allowed to open the front and rear cover at will, and the related internal parameters are changed. Otherwise, the normal operation of the flowmeter will be affected. Beware of the device gaskets to ensure that no protrusions enter the pipe to avoid interference with normal flow measurements. The flowmeter collects pressure on the flowmeter pressure port at the time of calibration. The debris in the pipeline should be cleared before the turbine front of the installation: debris, welding slag, rock, dust, etc. The filter introduced in the upstream device 5 micron mesh is used to block the droplets and sand. When the flowmeter is put into operation, the front valve should be slowly opened first, and then the rear valve should be opened to avoid damage to the turbine due to airflow shocks. Plus smooth oil should be operated according to the signboard. The number of refueling depends on the clean level of temperament, usually 2-3 times a year. The flowmeter may be damaged due to test pressure, purge piping or exhaust gas forming a turbine overspeed, and the turbine operating in reverse flow. Changzhou Chengfeng flow meter is three decades in the industry, Cheng Feng meter footprints all over the country, to understand the actual needs of customers, targeted to give them the best solutions and the most suitable products, the right is the best . 1. Welding Machines - A welding machine is an essential tool for any welding job. It is used to create a welding arc that melts the metal being joined, allowing it to fuse together.

2. Welding Electrodes - Welding electrodes are metal rods that are used to conduct electricity and create an arc. They are coated with a flux that helps to protect the weld from contamination and oxidation.
3. Welding Wire - Welding wire is used in the MIG welding process to feed the welding arc with a continuous supply of wire. It is available in different thicknesses and materials, such as stainless steel, aluminum, and mild steel.
4. Welding Helmets - Welding helmets are designed to protect the welder's eyes and face from the intense light and heat produced during welding. They come in different styles and designs, including auto-darkening helmets that automatically adjust to the brightness of the welding arc.
5. Welding Gloves - Welding gloves are used to protect the welder's hands from heat, sparks, and other hazards associated with welding. They are made from materials such as leather and Kevlar and come in different sizes and styles.
6. Welding Safety Glasses - Welding safety glasses are designed to protect the welder's eyes from the intense light and UV radiation produced during welding. They are available in different shades and styles.
7. Welding Filler Metals - Welding filler metals are used to add material to the weld joint to create a strong, durable bond. They come in different materials, such as stainless steel, aluminum, and bronze.
8. Welding Clamps - Welding clamps are used to hold the metal being welded in place during the welding process. They come in different sizes and styles, including C-clamps, locking pliers, and magnetic clamps.
9. Welding Flux - Welding flux is used to protect the weld from contamination and oxidation during the welding process. It is available in different types, including powder, paste, and liquid.
10. Welding Gas - Welding gas is used in the TIG and MIG welding processes to shield the welding arc from contamination and oxidation. It is available in different types, including argon, helium, and carbon dioxide.
