Talking about the Importance of Compressed Air Pipeline Compressed Air Pipeline Faults and Prevention Methods

It is believed that everyone knows that compressed air is the second largest source of power, second only to electricity. Compressed air is used in a very wide range of applications. Its applications range from petroleum, chemical, power, machinery, biochemical, national defense, scientific research and other industries and sectors. Nearly all production, processing and engineering require compressed air. Here we have to introduce: fault prevention methods and the importance of the compressed air line compressed air pipe.

The importance of the compressed air pipeline:

1, the selection of the pipeline is critical

The atmosphere contains corrosive gases, water vapor, hydrocarbons, and other impurities. Each cubic meter of air contains approximately 140 million solid particles. More than 80% of these particles have a particle diameter of less than 2 μm. It is easy to enter the compressed air system through the air compressor and the silencer filter. The air containing all kinds of impurities enters the air compressor after being passed through a simple filter and is compressed. Due to the high temperature and oxidation generated during the compression of the gas, the quality of the compressor's lubricating oil is reduced, and the solid acid is strongly acidic. Compressed air oil and water vapor together into the compressed air pipe network system, such as the use of traditional galvanized pipe or carbon Steel Pipe, the pipe wall will be rusted first, because of its iron is the active chemical properties of It is particularly prone to rusting, and when iron comes in contact with air, it reacts with the oxygen in the air, causing the molecules on the iron surface to become iron oxide, rust. The surface of iron exposed to the air is constantly oxidizing and rusting, making the iron soft and loose. The use of ordinary carbon steel pipe for a long time will naturally have corrosion impurities deposited inside the pipe. The end result is that the pipeline (including the weld site) corrodes and leaks. The contaminated air brings serious damage to the pneumatic equipment, pneumatic instruments and the quality of the end product, increases the maintenance cost of the system equipment, and causes a lot of leakage. funds. Practice has proved that heavy, contaminated and leaky seamless steel pipes and galvanized pipes are slowly being eliminated. The PVC pipes with a large number of safety hazards are also slowly moving away from this industry, replacing them with the new type of FSTpipe. ) Full-performance aluminum alloy compressed air pipeline. With its superior design, materials and production processes, it ensures the delivery of high-quality pure compressed air, protects the safety of end-use gas and the stability of output quality, and uses a high-performance O-ring seal. It also effectively prevents the occurrence of leaks.

2, the design and installation of the pipeline

In domestic factories and enterprises, the compressed air transmission pipelines are all linear and one-way pipelines, which will cause front-end jobs to work properly, and the back-end post pressure and flow supply will be insufficient. In addition, during the installation design, the setting of the sectional zone control valve was not taken into consideration, and failure of one zone or one device caused the entire plant to stop production. During installation, drainage problems are seldom taken into consideration. Many companies have very messy compressed air transmission pipelines. They fly in the air, but they also bury underground. They are complex and cannot drain. Some manufacturers also use PVC or PPR as a delivery pipe, because of its large expansion rate, and did not consider the issue of telescopic mouth. Therefore, in the design and installation of compressed air transmission pipelines, it is imperative to have pressure pipeline qualifications and professional design and installation and companies to design, plan and install. In order to ensure the normal operation of production companies, improve efficiency, reduce costs and ensure quality.

Failure of the compressed air pipeline and its prevention and control methods:

(1) Causes of leakage of safety valve and prevention methods

The safety valve spring bearing surface is not perpendicular to the spring centerline. When the centerline of the valve spring is not perpendicular to the bearing surface, the valve spring will be deflected when it is under pressure, resulting in uneven valve force of the safety valve, warping, leakage and oscillation, and even failure of the safety valve.

Control methods: Adjust the verticality of the valve spring bearing surface and the centerline of the spring and keep them perpendicular to each other. Clean the impurities and dirt between the safety valve and the valve seat. If necessary, re-grind to ensure the contact surface is tight. The valve spring of the safety valve shall be pressed tightly, and the thread and the sealing surface shall be well protected. Where there is damage, the valve shall be scraped and ground.

(2) Causes and Treatment of Air Leakage in Compressed Air Piping System

The reason for the leakage is often due to the poor quality of the materials and accessories used or the poor installation quality. The sinking of the brackets in the pipeline causes severe deformation and cracking of the pipeline. The water in the pipeline freezes to crack the pipe or fittings.

Treatment methods: repair or replace damaged pipe sections and pipe fittings, regularly eliminate water in the pipes to prevent freezing cracks, repair the bracket when the pipe bracket sinks, and adjust the pipe slope to facilitate drainage.
