Maintenance of common faults in pressure gauge calibration
The maintenance of various types of instruments is different because of its structural principle, and the actual maintenance methods are not the same. Talk about pressure gauge maintenance today.
The on-site pressure gauge has many models to choose from depending on the installation situation and the measurement medium. The most commonly used is the spring tube pressure gauge, in addition to stainless steel pressure gauges, pressure gauges, diaphragm pressure gauges. These pressure gauges, regardless of structure, problems, or need to know their accuracy, require an instrument pressure calibrator.
The most likely problem with on-site pressure gauges is that pressure indications are inaccurate, high or low indications are displayed, and indications do not return to zero. These problems are mostly experienced by field workers, telling maintenance personnel that a certain pressure gauge is broken. Maintenance, so the instrument personnel to open the calibration room repair. When you open the pressure gauge, you can roughly determine what the problem is. For example, if the indicator does not return to zero, there will be indications on the pressure gauge after dismantling. Of course, this situation may also be misjudged. This may be due to the viscous medium in the spring tube. Also, be careful when taking apart the pressure check valve. Causes the pointer not to return to zero. The pressure gauge at the outlet of the pump should be drained prior to disassembly to prevent leakage of medium. The pressure gauge after dismantling should discharge the medium in the spring tube for further maintenance. One is to completely reset the spring tube and the other is to clean the pressure gauge so that the dirty media does not contaminate other equipment.
When the pressure gauge is calibrated, it is connected to the calibration interface. According to the steps of pressure calibration, the indication and accuracy are accurate. If it is inaccurate, do echo adjustment. If all adjustments fail to meet the requirements, the spring tube will be scrapped. Other parts and components may be used as accessories according to specific conditions.
Pressure gauges are also very broad in practical industry applications. The problems encountered are far more than this, but in any case, the purpose of Anhui Weinstr is to do its best to serve every customer, no matter how much or less, Play a little bit to be satisfied!

Filter mesh refers to small aperture metal mesh or other materials with smaller apertures for a variety of different filtration, dust removal and separation requirements. They are widely used in shower panel, sanitary pipe systems, purifiers, electronic components, to remove contaminants or in applications, such as coffee machine, soya milk machine, to extract a filter cake. Because the metal mesh filters are one of the most durable filter media available, the material is mainly made of copper, iron, steel, nickel, stainless steel, alloy. It is acid resistant, alkali resistant, temperature resistant and wear resistant.
We customize diverse patterns metal microporous mesh with drawings provided by customers. We are equipped with professional metal etching equipment and exposure development equipment. Chemical metal etching filter mesh is a double-sided and simultaneous processing technology, which can make the product surface (positive and negative) smooth, without bumps, pits, burrs, warps, and flat mesh without deformation. Below are the advantages for customized metal filter mesh:
Flow Rate
One of the most significant advantages metal mesh has over most filter media used today is its ability to deliver an adequate flow rate. This is achievable as the wire diameter and mesh opening can be customized to perfectly match the contaminants you are filtering out, providing you with an enhanced level of filtration surface area.
Durability
300 series stainless steel is predominantly used. This helps create a filter that can withstand a wide range of impurities, pressure variations, and extreme temperatures without hindering the filter's accuracy. In addition, stainless steel is a very pliable material, allowing the filter to be formed to fit your filter system and hold its shape after several uses.
Accuracy
The weaving process used to construct mesh filters is heavily monitored from start to finish. As a result, the pore openings of the filter are exact and uniform throughout the filter. These precise pore opinings ensure that the end product, whether a filtered substance or a filter cake, is consistent and complies with industry standards.
Clean ability
As metal mesh features accurate pore openings, blinding and plugging are significantly reduced. This, combined with the enhanced flow rate, means system operators can clean the metal mesh easily. These two properties allow the mesh filter to be backflushed and purged of any unwanted debris with minimal pressure.
