Smms Spunmelt Nonwoven Production Line
SMMS non-woven fabric belongs to the technical extension of SMS non-woven fabric. Before there was no SMS one-step equipment a few years ago, people had no relevant concept of SMMS. With the promotion of SMS online one-step equipment technology and equipment, the popular SMMS non-woven fabrics and higher-end SSMMS, SMMMS, SSMMMS, SSMMSS and other multilayer composite high-performance non-woven fabrics have been extended. SMMS is made of spunbond nonwoven fabric + meltblown nonwoven fabric + meltblown nonwoven fabric + spunbonded nonwoven fabric, four-layer fiber web hot rolled. Have all the characteristics of ordinary SMMS non-woven fabric; anti-alcohol up to level 10 (ie 100% anti-alcohol); anti-static ability up to 108-1012; anti-oil; anti-plasma; mainly used in surgical gowns, surgical drapes, surgical kits Cloths, medical bed sheets, hand-washing suits, isolation suits, laboratory suits, advanced protective suits and other protective products can be made in different colors according to different customers' preferences. SMMS covers all the performance of SMS, and greatly expands the performance of SMS: bacteria isolation, hydrostatic pressure, strength, uniformity, softness, application areas. It can be concluded that the future application fields of SMMS will radiate and replace all aspects of people's lives.

The HN800 series eddy current sensor is a combination of a preamplifier and an eddy current probe. It is a non-contact linearized sensing system. The eddy current sensor is mainly used to measure the static and dynamic distance between the probe and the measured object. The object to be measured is generally ferrite. The alternating electromagnetic field of the probe is absorbed by the ferrite. The electronic circuit of the sensor senses and processes the change. Thereby, the displacement amount of the measured object is obtained. It has the advantages of long-term work reliability, wide measuring range, high sensitivity, high resolution, fast response, strong anti-interference ability, and no influence from oil and other media. Therefore, HN800 series eddy current sensor monitors on-line condition of large rotating machinery. Widely used in troubleshooting.
Axial position measurement: It indicates the possibility of wear of the thrust bearing or potential bearing failure.
Radial vibration measurement: The HN800 series eddy current sensor can indicate the working condition of the bearing and can detect mechanical faults such as rotor imbalance, misalignment and shaft crack.
The average radial position of the shaft in the bearing: it can be used to determine the azimuth, which is also an indication of whether the speed is stable and the shaft is centered.
Key phase signal: It is used to measure the rotational speed of the shaft and the phase angle.
Eccentricity: For large and small turbomachines, the shaft bending, ie the eccentricity, needs to be measured at start-up.
The SH-08 eddy current sensor debugging frame sensor is mainly used to measure the static and dynamic distance between the probe and the measured object. The measured object is generally ferrite, and the alternating electromagnetic field of the probe is absorbed by the ferrite. The electronic circuit of the sensor The amount of change is sensed and processed, thereby obtaining the displacement of the measured object, the displacement of the rotating mechanical shaft system, the vibration, the rotational speed, the expansion, the eccentricity, the oil film thickness on-line monitoring, the mechanical size, thickness, and surface roughness detection of the product.
The limit, counting and other precision control of industrial process automation can be widely used in petrochemical, metallurgy, steel, electric power, aerospace, pharmaceutical, machinery manufacturing and other industries.
The sensor can dynamically and non-contactly measure the relative vibration displacement (such as shaft vibration, etc.) of the metal conductor to be tested and the end face of the probe.
The sensor can measure the relative displacement (such as axial displacement, differential expansion, etc.) of the metal conductor to be tested and the end face of the probe in a static and non-contact manner.
In engineering vibration, the operating state and operational failure analysis of rotating machinery and reciprocating operating machinery, using vibration monitoring is an authoritative method of Zui, which has a time-reality. The imbalance of the rotor, the misalignment of the two connected rotors, the bearing wear, the shaft cracks and the dynamic and static friction of the rotor blades with the casing are mainly reflected in the changes in the amplitude, phase and frequency of the vibrations. It is the key information of Zui and it is easy to measure. YH-DO-A1-B60-D1 eddy current sensor eddy current displacement sensor has long-term high reliability, non-contact measurement, strong anti-interference ability, is not affected by oil and water and other media, and has wide application range and simple structure. It is often used for long-term real-time monitoring of shaft vibration, axial displacement, shaft speed, housing expansion, etc. of large rotating machinery, and effectively protects the safe operation of equipment. Trend analysis and fault diagnosis of monitoring data can also be performed to predict maintenance and troubleshooting. Radial vibration measurement of the sensor: It indicates the working condition of the bearing and can measure the axial position measurement of mechanical faults such as rotor imbalance, misalignment and shaft crack: it can indicate the wear or potential of the thrust bearing The possibility of bearing failure The average radial position of the shaft in the bearing: it can be used to determine the azimuth, which is also an indication of whether the speed is stable and the shaft is centered.
Eccentricity: For large and small turbomachines, the shaft bending, ie the eccentricity, needs to be measured at start-up.
Key phase signal: It is used to measure the rotational speed of the shaft and the phase angle.
