In general, there are some problems with nitrogen production opportunities as follows:
1), air filter, freeze dryer, air storage tank does not have normal drainage.
2) The freeze dryer is not cooled and no personnel are found in time.
3) There is no activated carbon degreaser in the front of the nitrogen generator.
4) The nitrogen generator muffler has a large amount of black particles ejected.
5) Some pneumatic valves are damaged.
6) The air filter cartridge has not been replaced until now.
Solve the problem as follows:
1) Install a timed drain on the air storage tank drain to reduce the post-load pressure.
2) The normal use of the equipment should pay attention to check whether each timed drainer is properly drained, whether the air pressure meets 0.6Mpa or more, and whether there is a cooling effect when comparing the inlet and outlet of the dryer. Check if the nitrogen purity is stable.
3) The air filter must be done at a frequency of 4,000 hours.
4) The activated carbon filter can effectively filter the oil and can extend the service life of the high-quality carbon molecular sieve. The activated carbon needs to be replaced once in 3000 hours or 4 months.
5) Pneumatic valve and solenoid valve of nitrogen generator are recommended for each model of action components to prevent future troubles.
Nitrogen machine maintenance and construction Our company's on-site guidance steps are divided into:
1) Preparations Your company is responsible for on-site construction, 5 personnel, a set of tools, welding machines, cutting machines, corresponding pipelines, and a set of parts purchased by our company.
2) Construction steps: simply clean the site, cut off the gas and power off, the two remove the suction tower head, the two remove all the pipes of the nitrogen generator, remove the waste in the adsorption tower, need to be cleaned, check the top and bottom of the adsorption tower of the nitrogen equipment Whether the manifold is damaged or damaged and repaired in time. All pipes should be cleaned with compressed air, pneumatic valves should be checked for damage to the seals, and pneumatic valves need to be replaced. The air treatment part of the filter is updated, and the activated carbon filter pipeline is modified by one person for simultaneous construction. All work is completed, all pipes and valves are installed, ventilation is energized, the entire system pipe is purged once, and the carbon molecular sieve charging operation is started. The on-site instructor guides, after starting the charging, the nitrogen generator is started, and the interfaces are checked for leaks. Gas, while testing nitrogen purity and productivity.
3) After all the projects are completed, the on-site instructors will introduce the daily use and precautions to the responsible personnel of your company.
After the equipment repair and transformation is completed, your company will strictly follow the precautions, and then the problem will be repeated. Our company promises as follows:
1) Nitrogen machine purity: 98%
2) Nitrogen generator capacity: 200 cubic meters per hour
3) Nitrogen pressure: adjustable between 0-0.65Mpa
4) The service life of carbon molecular sieves is reduced by 5% per year (because carbon crystallization is aging, it is inevitable)
5) CMS-220 carbon molecular sieve service life manufacturer recommends 5-6 years, our company recommends 4 years to replace.
6) All parts of our company are guaranteed for one year, except for normal consumables, except for powdered carbon molecular sieves for 4 years, except for normal aging capacity.
7) The carbon molecular sieve warranty will not be sprayed within one year. Except for improper use (such as: maintenance under the maintenance plan specified by our company), we will provide maintenance service for nitrogen machine for free. Http://news.chinawj.com.cn
