Maintenance of pressure sensor in use
Sms Spunmelt Nonwoven Production Line The sms non-woven fabric production line is used to produce polypropylene fiber spun webs and hot-rolled reinforced non-woven fabrics. Using polypropylene as the main raw material, supplemented by color masterbatches and additives such as anti-oxidation, anti-pilling, and flame retardant, we can produce polypropylene spunbonded hot-rolled non-woven fabrics with different colors, different properties, and suitable for various purposes. It has different uses and is widely used in medical treatment, sanitation, agriculture, construction, geotechnical industry, making non-woven protective clothing, etc.
Various special treatments are carried out on non-woven fabrics to meet the requirements of customers for various special properties of non-woven fabrics. The treated non-woven fabric has anti-alcohol, anti-blood, and oil-resistant functions, and is mainly used in medical surgical gowns and surgical drapes. Antistatic treatment: Antistatic non-woven fabrics are mainly used as materials for protective equipment that have special environmental requirements for static electricity. Absorbent treatment: Absorbent non-woven fabrics are mainly used in the production of medical consumables, such as surgical drapes, surgical pads, etc. Flame-retardant treatment: Flame-retardant non-woven fabrics are widely used in furniture products and aviation products. Antibacterial deodorization and photocatalyst effect treatment: This kind of non-woven fabric is mainly used in the field of household products. Anti-ultraviolet treatment: Anti-ultraviolet, anti-aging non-woven fabrics are mainly used in agricultural covering fabrics, car covers and other fabrics where sun protection and anti-aging effects are required. Fragrance treatment: Fragrance non-woven fabrics are used in sanitary products (mint, lemon, lavender, etc.).

First, prevent the dross from depositing inside the duct and the sensor coming into contact with corrosive or overheated medium.
Second, when measuring gas pressure, the pressure tap should be open at the top of the process pipe, and the sensor should also be installed in the upper part of the process pipe so that the accumulated liquid can be easily injected into the process pipe.
Third, when measuring the liquid pressure, take the pressure port should be opened in the side of the process pipeline to avoid deposit residue.
Fourth, the pressure tube should be installed in a small temperature fluctuations.
Fifth, when measuring the liquid pressure, the sensor should be installed in a location where the impact of the liquid (water hammer phenomenon) should be avoided so as to avoid over-voltage damage to the sensor.
6. When winter freezing occurs, sensors installed outdoors must adopt anti-freezing measures to avoid the loss of the sensor due to the volume expansion of the ice in the pressure-inducing port.
VII. When wiring, pass the cable through the waterproof connector or the coiled tube and tighten the sealing nut to prevent rain water from leaking through the cable into the transmitter housing.
8. When measuring steam or other high-temperature medium, a condenser such as a buffer tube (coil) must be connected, and the operating temperature of the sensor should not exceed the limit.
The composite production line can be replaced with different configurations to produce S, SS, SSS and other series of products to meet the needs of customers in the polypropylene spunbond non-woven market for different purposes.
