Stainless steel pressure gauge Y-100BF

Y-100BF stainless steel diaphragm pressure gauge

Diaphragm pressure gauge, also known as micro pressure gauge. The structural principle is to weld two concentric diaphragms together to make a hollow diaphragm box for the displacement of the diaphragm and the sensitivity of the pressure gauge. The diaphragm box is used as an elastic element to measure small pressure gauges called diaphragm box pressure gauges.

The membrane box pressure gauge consists of a measuring and rotating indicator mechanism and a housing. The working principle of the instrument is based on the elastic deformation of the end of the corrugated membrane box under the pressure of the medium, which is then amplified by the rotation of the pulling rod gear rotating mechanism. The measured value is gradually indicated on the dial by the pointer fixed on the gear shaft.

Product Usage

The membrane box pressure gauge uses a membrane box as a component for measuring small pressures. Suitable for measuring micro pressure and negative pressure of copper alloys that do not corrode and do not contain hazardous gases, widely used in boiler ventilation, gas pipelines, devices, and other similar equipment. The stainless steel diaphragm pressure gauge is made of stainless steel material according to the pressure and housing. Applied to the measurement of micro pressure and negative pressure of various gas media in processes with high corrosion resistance requirements. The stainless steel diaphragm pressure gauge is a micro pressure gauge with corrosion resistance developed based on the structural characteristics of the original diaphragm pressure gauge. Applied to equipment such as boiler ventilation and gas pipelines, measuring the micro pressure and negative pressure of various gas media in processes with high corrosion resistance requirements. Degree level: 2.5.

Precautions for using pressure measuring instruments

(1) The instrument should be installed perpendicular to the horizontal plane; (2) Is the measurement point of the instrument located at the same horizontal position as the instrument installation considering the correction of additional height errors; (3) The distance between the instrument installation site and the measuring point should be as short as possible to avoid slow indication; (4) Ensure sealing and prevent leakage, especially for flammable and explosive gas media as well as toxic and harmful media.

Additional devices should be added to the instrument when used in the following situations, but no additional errors should be generated, otherwise correction should be considered.

(1) In order to ensure that stainless steel pressure gauges are not corroded by the measured medium or affected by high viscosity or crystallization, isolation devices should be installed;

(2) To ensure that the instrument is not affected by rapid changes or pulsating pressure of the measured medium, a buffer is installed. Especially during sudden increases and decreases in pressure, it is easy for pressure instruments to be damaged or scrapped, and even for spring tubes to crack and leak;

(3) In order to ensure that the instrument is not affected by vibration, pressure instruments should be equipped with vibration reduction devices and fixing devices;

(4) In order to ensure that the instrument is not affected by the high temperature of the measured medium, a full bend device should be installed;

(5) Special instruments are strictly prohibited from being used for other purposes, and measurements must not be made without special and reliable devices. It is even more strictly forbidden to use general pressure gauges for pressure measurement of special media;

(6) For newly purchased pressure detection instruments, it is necessary to perform metrological calibration before installation and use to prevent vibration, damage, or other factors affecting the accuracy of the pressure instruments during transportation.

Widely used in industrial sectors such as petroleum, chemical, synthetic fiber, metallurgy, power plants, etc., where high requirements for corrosion resistance and vibration resistance are needed, to measure the pressure of various fluid media.

structural principle

A stainless steel pressure gauge consists of a pressure gauge (including a connector, spring tube, flow limiting screw, etc.), a gear transmission mechanism, a reading device (pointer and dial), and a housing (including a case, cover, glass, etc.). The outer shell is of an airtight structure, which can effectively protect the internal components from being affected and contaminated. For instruments that are filled with liquid (usually silicone oil or glycerin) inside the casing, they can resist the effects of severe working vibrations and fluctuations in medium pressure.

The main feature of Sinumerik 808D is its complexity and ease of use. This product is jointly created by engineers from China and Germany. Siemens has stopped research and development of its existing leading CNC product development platform based on local market demand, and the product cost has been strictly stopped in accordance with German regulations, ensuring high popularity of CNC.

Meanwhile, 2017 also made an appearance at this conference. The concepts of intelligent manufacturing and Industry 4.0 are being highly promoted, corresponding to the release of "Manufacturing 2025" in the middle of last year. In the transition from manufacturing to intelligent manufacturing, the limited business opportunities included in "factories" have already impressed the business community, which is one of the early multinational enterprises to smell the huge business opportunities.

The second-generation SIMATIC HMI panel adopts a 7-inch or 9-inch high brightness 16 million color widescreen display with an aspect ratio of 16:9, which enables highly complex and specific process flows... Siemens SINAMICSG120 series frequency converter SINAMICSG120 is a modular frequency converter that includes various functional units.

We tracked a group of people who moved from the suburbs to the city because there were many construction sites in the suburbs, and the PM2.5 concentration in the air was actually higher than in the city. But after our physical examination, we found that these people's blood pressure, inflammatory factors, coagulation targets, and lung function improved after entering the city.

The Ministry of Environmental Protection believes that with the implementation of the "Ten Measures for Air Quality on Chinese New Year's Eve" and related measures, the overall air quality in 74 cities has improved, and the air quality in the Beijing Tianjin Hebei region has improved significantly. In addition, in the first half of 2014, the monitoring results of key pollution sources showed that the compliance rate of major pollutants from nationally controlled key pollution sources was slightly higher. Three measures, including appointing community and administrative village cadres as food safety information officers, have strengthened the responsibilities of the authorities.
