Smart city underground pipe network mini gas pump application case

Industry introduction:

With the implementation of smart city construction nationwide, smart underground pipe networks and smart comprehensive pipe corridors have become an important part of smart city business. Through the integration of underground gas, power supply, water supply, and sewer pipe networks, the application of Internet of Things (IOT) technology, Sensor technology and mobile communication technology can realize real-time dynamic detection of the status of underground pipe networks, thus ensuring the safe and smooth operation of the “main arteries” of smart cities.

Mini gas pump application introduction:

As one of the core parts of the smart underground pipe network solution, customers deploy self-developed gas detection smart terminals to analyze toxic, harmful and combustible gas components in the underground pipe network 24 hours a day, and provide real-time alarms, ventilation and emergency response. The mini gas pump product developed by our company is used as the core device of the gas detection intelligent terminal to realize the gas sampling and transportation functions.

Project difficulties:

1. The composition of sewer gas is complex and contains various harmful gases (hydrogen sulfide, methane, ethane, etc.). In addition, the humidity in underground pipelines is high, which easily corrodes the metal parts inside the mini gas pump. The working conditions of the mini gas pump are harsh, which has a negative impact on product quality, material, and resistance. Corrosion capabilities have very high requirements. .

2. The gas contains dust impurities and high humidity, which accumulates for a long time and easily blocks the pipeline, thus affecting the life of the pump body.

3. 24-hour online monitoring requires the mini gas pump to operate continuously for 24 hours without stopping. It requires long life and no shutdown maintenance. It puts forward extremely high requirements for the life, reliability and maintainability of the mini gas pump.

Solutions:

1. Chengdu Hilin Technology C09L quality version mini gas pump has passed the 5500-hour continuous working test. Under 7*24 hours of non-stop maintenance conditions, it can work continuously for more than 200 days, which greatly reduces the inspection and maintenance pressure.

2. Chengdu Hilin Technology C09L quality version of the mini gas pump main control circuit board has all passed moisture-proof and anti-corrosion treatment, which is more suitable for working in harsh environments and avoids PCB corrosion in humid and corrosive environments.

3. The gas contact material of the C09L quality version of the mini gas pump is made of reinforced nylon and EPDM rubber, which has good corrosion resistance to common acids and alkali gases and liquids.
