The operating condition or operating condition of the flow meter directly affects its metering performance. The most direct influence of the operating pressure or temperature change on the flow meter is the change of its metering cavity. Changzhou Chengfeng introduces you to the performance of electromagnetic flowmeters and turbine flowmeters:
1. Electromagnetic flowmeters: Changes in physical properties such as viscosity and density of the measured medium can have indirect effects, but indirect effects can be considered when correcting the effects of physical properties. Because of the complexity of the structure and shape of the flow meter and the discreteness of the processing and assembly, it is generally impossible to use a calculation method to accurately correct the cavity with the change of the operating conditions, and the data for the flowmeter is fitted out according to the test data. It is also not possible to have an empirical formula that meets the accuracy requirements.
2. In a broad sense, the flow conditions of the measured medium's uniformity, gas (liquid) content, and impurity content also fall within the scope of the flowmeter's operating conditions, but its influence on the performance of the flowmeter is even more complicated, sometimes online. Real-flow verification is also difficult to solve.
Turbine flowmeter: For volumetric flowmeters, in the type identification, prototyping test, or quality control spot check of a flow meter, after the natural aspirated engine is converted to a supercharged engine, whether it is using exhaust gas turbocharger Or the supercharger, vortex flowmeter will encounter the problem of high intake air temperature, naturally aspirated engine intake air temperature no matter what the state of the engine is no big change, whether it is installed in the air flow meter There is not much difference between the inlet manifold or the wind box not far from the throttle; for the speed turbine flowmeter, the change of operating conditions will cause the flow area to change, which will cause the change of the meter coefficient. If the operating condition of the flow meter is checked to be the same as or close to the actual use, the offline verification can meet the requirements. However, due to the complexity and variability of operating conditions, off-line verification often cannot reproduce actual operating conditions. Only on-line real-flow verification can solve high-accuracy flow measurement problems, otherwise additional errors should be considered.
Changzhou Chengfeng Flow Meter Co., Ltd., as a well-known electromagnetic flowmeter manufacturer in China, has a history of more than 30 years. The electromagnetic flowmeter developed and produced by the company has sophisticated materials, superior quality, and exquisite technology. The sampling rate of continuous sampling inspection is 100%. The service life of each high-precision electromagnetic flowmeter is 5-8 years, and the failure rate is extremely low. After a long period of use, it can still work stably after failure maintenance. Maybe you will feel that this is a matter of course. Indeed, Cheng Feng also understands it so that it strives to achieve the same quality as imported. These are all unmatched by some low-priced products in the current market. After an impetuous production and put into the market, they will be damaged for 1-2 years and cannot be repaired. From the perspective of environmental protection, it is undoubtedly a large amount of industrial waste. In terms of after-sales service, Changzhou Chengfeng Instrument provides 24-hour gold medal service in the most user-friendly mode, which truly allows customers to buy with confidence. Changzhou Chengfeng made a real domestic high-end electromagnetic flowmeter.
Metal alloy powders are commonly used in thermal spray processes to coat surfaces with a protective or functional layer. These powders are typically made by combining different metal elements in specific compositions to achieve desired properties such as corrosion resistance, wear resistance, or thermal conductivity.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
