Fault analysis and elimination: Cryogenic Liquid Pump is installed on the main power switch and compressor switch. When starting the compressor you should turn on the main power switch, if the main power switch or compressor switch trips immediately, it means that the power supply voltage or phase sequence error error, need to access the correct power phase sequence and voltage. If the main power switch and compressor switch has not tripped, check for proper remote controller installation and use.

Therefore, the compressor cannot be started error is usually due to a power or remote controller is not installed properly. Of course, compressor circuit damage and PSA Oxygen Generator mechanical damage can also cause the compressor not running, is the most common fault due to a power supply phase sequence error, there will be a phase detector, a component is damaged. ]]> https://ameblo.jp/gasindustry/entry-11977819103.html Fri, 16 Jan 2015 11:30:46 +0900 High Purity Nitrogen Plant in the large-scale equipment of constant force, King size air separation plant has entered the era of nationalization.

Initially, the production scale of air separation plant in China can only produce 20m3/h (oxygen) of oxygen. Later developed into 20000m3/h, 30000m3/h, 50000m3/h and 60000m3/h of large scale air separation equipment capacity. But now, China has 60,000 grade LNG Cryogenic Liquid Pump-rich operating experience. Four empty branches are delivered in China, has made gratifying progress. Kaifeng air separation group and group completed 80,000 level of Sichuan air separation unit ASU technology research and development, and into the prototype stage; Hangzhou hangyang AG last year with the Iran card group signed up to 120,000 level design of air separation plant has been completed, signed a contract with Guangxi putting 80,000 this year ranks ASU enters the installation phase.

The history of air separation unit in China show that, Water Bath Vaporizer like larger, but with international air separation units compared to the more than 100-year history, domestic in both technology and equipment level, there are still some gaps and, therefore, still needs to strengthen independent innovation and domestic research and development, to snap the international advanced level. ]]> https://ameblo.jp/gasindustry/entry-11967600955.html Mon, 22 Dec 2014 13:02:06 +0900

China has only 20m3/h from the early production of the Air Separation Plant size (oxygen) of oxygen. Developed to produce 20000 m3/h, 30000 m3/h, 50000 m3/h and 60000m3/h the ability of large scale air separation equipment, and has completed the research phase, upcoming manufactured 80000m3/h large air separation plant capacity.

ASU is a large and complex system, consists of the following subsystems: dynamical systems, purification systems, refrigeration systems, heat exchangers, distillation systems, conveyor systems, liquid storage and control systems, and so on. Mainly refers to the raw material air-compressor. LN2,LO2,LAr,LCO2,LNG Tank products such as oxygen and nitrogen by Cryogenic separation of air, is essentially done through energy conversion. Of energy is mainly determined by the raw material chosen for an air compressor. Accordingly, total energy consumption of air separation required mostly raw materials and energy consumption of the air compressor.

Air cooling systems (cooling system) and molecular sieve purification systems (purification system). Raw material by compression of the air temperature is high, air cooling system through contact with the heat exchanger reduces the temperature of the air, as well as washing the acid and other harmful impurities. Molecular sieve purifying system to remove moisture from the air, carbon dioxide, acetylene, propylene, propane and nitrous oxide and other substances harmful to the operation of air separation equipment.
Refrigeration system: LO2/LN2/LAr Cryogenic Liquid Pump through expansion of refrigeration, refrigeration of the entire ASU strictly follow the classic refrigeration cycles. But usually refers to ASU refrigeration equipment, mainly refer to: Expander. ]]> https://ameblo.jp/gasindustry/entry-11964969562.html Mon, 15 Dec 2014 12:43:34 +0900
