Application of Turbine Flowmeter in West-East Gas Transmission

Brief Description Turbine flowmeters are used in a wide range of measurement objects: petroleum, organic liquids, inorganic fluids, liquefied gases, natural gas, gas, and cryogenic fluids. In Europe and the United States, the turbine flowmeter is the natural gas meter next to the orifice flowmeter. In the Netherlands alone, more than 2,600 gas turbine flowmeters of various sizes and pressures from 0.8 MPa to 6.5 MPa are used on the natural gas pipeline. Has become an excellent natural gas flow meter. It is also widely used in trade measurement in China's West-East Gas Pipeline, the second line, and the Sichuan-East Gas Pipeline.
Introduction to turbine flowmeter
1. Turbine flowmeter is a speed flowmeter with high precision, good repeatability, no zero drift, high range ratio, simple structure, less moving parts, high pressure resistance, wide measuring range, small size and light weight. , the pressure loss is small, and the maintenance is convenient. Turbine flowmeters have high-quality bearings and are specially designed with baffles, which greatly reduce wear and tear, are insensitive to peaks, and even give reliable measurement variables under harsh conditions. Flow range: 5~25000m3/h, connection diameter: DN50~600, pressure rating: PN10/16/25/40/100.
2, turbine flowmeter category: plug-in turbine flowmeter; gas turbine flowmeter; intelligent turbine flowmeter; liquid turbine flowmeter; clamp type liquid turbine flowmeter; anti-corrosion turbine flowmeter
3. Working principle of turbine flowmeter: When the gas enters the flowmeter, it first passes through the special structure of the leading fluid and accelerates. Under the action of the fluid, because the impeller blade and the fluid flow direction form a certain angle, the turbine generates the turning moment at the turbine. After the customer's resistance torque and friction torque start to rotate, when the moments reach equilibrium, the speed is constant, and the turbine rotation speed is linear with the flow rate. The speed of the impeller is decelerated by a pair of gears, while a sealed magnetic coupling transmits the rotation to a mechanical counter external to the meter. Using the principle of electromagnetic induction, the magnetic flux is periodically changed by the rotating tip of the impeller blade, so that a pulse signal proportional to the volume flow of the fluid is induced at both ends of the coil, and the frequency of the pulse signal is measured to obtain the flow rate. The turbine flow meter is used with a flow computer (or integrated calculator). The flow computer has pulse, temperature and pressure detection channels and is equipped with various communication interfaces.
4. Turbine flowmeter structure: It consists of the body, the guide body (flow deflector), the impeller, the shaft, the bearing and the signal detector.

Turbine flowmeter installation

1. Before installing the turbine flow meter, the gas pipeline should be clean, free of water, dirt and welding slag. These impurities can damage the impeller blades and mechanical parts. When the measured medium is unclean, a filter should be added.
2. The turbine flowmeter is sensitive to the flow velocity distribution distortion and the swirling flow in the pipeline. Therefore, it is necessary to equip the straight pipe section of the necessary length according to the upstream resistance type. Generally, the upstream section should have the length of the straight pipe section of the shortest 10D, and the downstream should have the straight pipe section of the shortest 5D. Length (D is the nominal diameter of the flowmeter). If there are complex chokes such as cyclones, space joints, and pressure regulators upstream of the flowmeter, the rectifier should be installed at the 5D upstream of the flowmeter.
3. The flowmeter should be installed horizontally to avoid vertical installation. If there is water or gas in the pipeline, the flowmeter piping should be inclined so that the liquid can flow out of the flowmeter. If the flowmeter is installed vertically, the flow of fluid should be downward. of.
4. Ensure that the flow direction of the fluid is consistent with the direction of the arrow on the instrument housing and must not be reversed.
5. The measured medium should not be corroded by the turbine, especially at the bearing, otherwise measures should be taken.

Turbine flow meter activation

1. The instrument equipped with the oil pump fills the oil chamber with oil before use and fills the oil according to the cycle requirements; the turbine flow meter without the oil pump does not need maintenance.
2. Before commissioning, check whether the turbine flowmeter verification certificate and the flow meter of the supporting instrument are consistent with the meter coefficient setting.
3. Start-up specifications for turbine flowmeters. Note that during operation, high-speed pressurization that is violently oscillated or too fast can damage the flowmeter.

maintain

1. Check its safety and operating status regularly. If there has been excessive pressure and the device has been vibrating abnormally or otherwise very dirty, the turbine flow meter must be inspected.
2. Regularly check the pulse frequency value of the matching flow computer.
3. For the inspection of the impeller, the inspection of the impeller can be carried out by removing the sensor or dead plug, and turning the impeller to determine whether the rotation is flexible and whether there is a broom phenomenon. Note: Moving the sensor probe will damage the flowmeter's seal.

Summary Turbine flowmeters are used as trade meters, and proper use and maintenance minimizes service life and accuracy.

Portable Hydrogen Water Bottle

What is a hydrogen-rich water bottle?

The hydrogen-rich water bottle mainly produces hydrogen by electrolyzing water, and then pressurizes the hydrogen molecules into the water molecules to form hydrogen-rich water rich in hydrogen molecules. The emergence of hydrogen-rich water bottles has greatly met the needs of people who pursue healthy drinking water. While meeting basic drinking water needs, they can also replenish sufficient hydrogen molecules into the body.

So what are the effects of hydrogen molecules on the human body, and why do we drink hydrogen-rich water?

There are many ways to replenish the body with extra hydrogen molecules, such as inhaling hydrogen, drinking hydrogen water, taking hydrogen water baths, injecting high-concentration hydrogen salt water, hydrogen molecule tablets, etc. Different methods have different effects, but the ultimate goal is to use the selective antioxidant properties of hydrogen molecules. Here are some benefits of drinking hydrogen water

1. Antioxidant effect

Free radicals are constantly produced in the human body, and too many free radicals can damage cells, causing various chronic diseases and aging processes. The hydrogen in hydrogen water has selective antioxidant capacity, which can neutralize harmful free radicals in the body, such as hydroxyl free radicals and peroxynitrite anions, and reduce the damage of oxidative stress to the body.

2. Relieve fatigue

Under high-intensity work, exercise or mental stress, the human body is prone to fatigue. Some studies have shown that drinking hydrogen water may help relieve fatigue. Hydrogen may improve the body's anti-fatigue ability by regulating the body's metabolism and energy production process, making people feel more energetic.

3. It may have an auxiliary therapeutic effect on certain diseases

1. Metabolic diseases: Studies have shown that hydrogen water may have a certain auxiliary therapeutic effect on metabolic diseases such as diabetes and hyperlipidemia. Hydrogen may play a certain inhibitory role in the development of these diseases by improving insulin resistance and regulating blood lipid metabolism.

2. Neurological diseases: For some neurological diseases, such as cerebral ischemia, Parkinson's disease, Alzheimer's disease, etc., hydrogen water may also have a certain protective effect. Hydrogen may protect nerve cells and improve nervous system function by reducing neuroinflammation and inhibiting oxidative stress.

3. Sports injuries: For sports enthusiasts, drinking hydrogen water may help relieve muscle soreness and fatigue after exercise and promote body recovery. Hydrogen may accelerate the repair of sports injuries by reducing oxidative damage and regulating inflammatory responses.

How to choose a trustworthy hydrogen-rich water bottle for yourself, your family, and your friends?

When you want to try a hydrogen-rich water bottle and open the webpage, you will see a wide range of products. They are of different shapes and prices vary greatly. At this time, you only need to place an order according to your needs. But you need to avoid those products that are of poor quality and may be harmful to the body.

1. Electrolyzer. The electrolyzer is the core component of the hydrogen water bottle. It is mainly responsible for electrolyzing water into hydrogen ions and hydroxide ions, and then filtering hydrogen molecules through the exchange of proton membranes to form hydrogen gas. Hydrogen gas then enters the water molecules under pressure to become hydrogen water. The electrode sheets and proton exchange membranes used in some cheap models are not of high quality, and may also cause the production of substances that are harmful to health, such as ozone and hypochlorous acid. Our suyzeko portable hydrogen water bottle uses titanium electrode sheets and platinum-coated proton exchange membranes to ensure that every customer drinks healthy hydrogen water without impurities.

2. The concentration of hydrogen water. Generally, hydrogen water with a concentration of more than 800ppb can be called hydrogen-rich water, but hydrogen molecules can easily escape from water, so you need to drink the hydrogen water in a short time. You can choose the product with the concentration you want. Generally, the higher the concentration, the higher the production technology requirements, so the cost will be more expensive. Our suyzeko's latest generation of hydrogen water bottles can produce 6000ppb hydrogen water, with 5-minute mode (about 3000ppb) and 10-minute (about 6000ppb) working modes.

3. Material. Because hydrogen is extremely small, it can penetrate glass and most metals, and it can easily escape from water, resulting in a lower concentration of hydrogen water. Aluminum bottles can store hydrogen water for a longer time. Our suyzeko hydrogen water bottles use aerospace aluminum shells and food-grade PC, which are lighter and can delay the escape of hydrogen from water.
