Air quality and water quality monitoring and treatment instruments that were previously only available in professional institutions are now expected to enter ordinary people. The PM2.5 situation in the home environment and the harmful gases left in the home decoration can all be answered at home. Recently, the home monitoring and purification integrated machine developed and manufactured by Sichuan Xianhe Environmental Protection Technology Co., Ltd. is about to go offline and enter the market.
Piston seal is a kind of seal used to seal between piston and cylinder, usually used in hydraulic system and Pressure system. The piston seal can prevent liquid and gas leakage, and also prevent external impurities from entering the system, thus maintaining the normal operation of the system.
Piston seals can be classified based on their structure and material. According to different structures, piston seals can be divided into unidirectional seals and bidirectional seals. A unidirectional seal can only prevent the leakage of liquid or gas from one direction, while a bidirectional seal can prevent the leakage of liquid or gas from both directions. According to different materials, piston seals can be divided into rubber seals, polyurethane seals, polytetrafluoroethylene seals, etc.
In hydraulic systems, piston seals are typically used to seal hydraulic cylinders and pumps. The piston seals in hydraulic systems need to have characteristics such as high temperature resistance, corrosion resistance, and wear resistance to ensure long-term stable operation of the system. In Pressure system, piston seals are usually used to seal cylinders and pumps. The piston seals in the Pressure system need to be resistant to high pressure, low temperature, wear and other characteristics to ensure the normal operation of the system.
In addition to hydraulic system and Pressure system, piston seals can also be used in other industrial fields, such as automobile, aviation, machinery, etc. In the automotive industry, piston seals are commonly used in engines to ensure normal engine operation. In the aviation industry, piston seals are commonly used in the hydraulic system of aircraft to ensure normal takeoff, landing, and flight. In the field of machinery, piston seals are commonly used in hydraulic and press machines to ensure the normal operation of the machine.

The home air monitoring and purification machine developed by Sichuan Xianhe is similar to the air-conditioning fan used in the past. It has a 5-inch large touch screen display through real-time monitoring data in the real air. At the same time, after monitoring, simply press the “Purify†button on the control panel, the purging function is activated, and the front and back changes of the air value can be seen through the monitoring screen.
The air-monitoring and purifying integrated machine developed by Sichuan Xianhe, based on its advanced environmental monitoring technology, is a new patented product that can monitor PM2.5, formaldehyde, VOC, temperature and humidity in real time for civil air environment. The air pollution level, health reminder, etc. are generated, and the purification system includes five-fold filtration and six-fold purification. The pre-filter removes hair and large particles, and can be washed to completely remove dust and harmful gases. The medical grade HEPA filter can remove 0.3 micron. And above dust; military grade carbon crystal filter can absorb formaldehyde, VOC; photocatalyst UV lamp can decompose formaldehyde, VOC kills bacterial virus; finally there is a unique water respiratory system, moisturizing and fresh air while sterilizing and purifying.
In addition to the introduction of purification equipment, Xianhe also developed an intelligent cloud processing system. Users who purchase civilian monitoring and processing equipment, their real-time data will enter the large database in the company's back office, and install the APP client on the customer's mobile phone. If the monitoring data exceeds the standard, the background will automatically generate an alarm and send it to the customer's mobile phone. The equipment is damaged and the background can be monitored and repaired in time. At the same time, the data of thousands of households will also serve as a part of the entire social environment, providing reference for relevant institutions and decision makers.
