9. Expand the use of other areas

In addition to the above industries， nitrogen generators are also widely used in coal mines， injection molding， brazing， tire nitrogen filled rubber， rubber vulcanization and many other fields. With the progress of science and technology and the development of society， the application field of nitrogen devices is becoming more and more extensive. Field gas (nitrogen generator) has gradually replaced the traditional nitrogen supply methods such as liquid nitrogen evaporation and bottled nitrogen because of its advantages of low investment， low cost and convenient use.

About motion energy consumption

1. Action and energy saving effect of nitrogen generator

The adsorption tower of the nitrogen generator is switched once a minute， and the pressure rise time of each switching is only 1 ~ 2 seconds， that is， the instantaneous gas consumption is very large. Without the buffer effect of the air storage tank， the compressed air directly enters the system and can not process a lot of compressed air in an instant. In this way， a lot of compressed air containing water and oil directly enters the nitrogen generator， which must poison the molecular sieve， Shorten the service life of molecular sieve， reduce the gas production rate and add the user's application cost.

2. Provide stable air source

If there is an air storage tank in the nitrogen generator system， the output air of the main engine has a buffer， the air source can be better maintained at a set value， and the gas consumption system can obtain a stable pressure， which is very necessary for the application of modern chemical plants.

3. Good air quality

The compressed air from the nitrogen generator is mainly sent to the air storage tank. The air here will stay for a certain time， which can accumulate impurities， water and other foreign matters in the air， and the temperature of the compressed air is also reduced. Even without a freeze dryer， it can send out relatively high-quality air.

4. In fact， the role of savings is the same as a reservoir. The air compressor is a gas source， while the air tank is a reservoir. The air storage tank can set the air pressure balance within a certain pressure scale according to the setting， buffer the instability of the air pressure and reduce the launching times of the main engine. Other air storage tanks can also play the role of accumulating impurities， water and other foreign matters in the air.

About safe use

1. Do not put it in the sun， rain， wind or places with relative humidity greater than 85%. Do not place in dusty， corrosive or combustible gas environment. Do not place it in a place where there is a risk of vibration and condensate freezing. Do not be too close to the wall to prevent poor ventilation. It is not necessary to use it in the environment with corrosive gas. The dryer with copper pipe antirust treatment or the dryer with stainless steel heat exchanger shall be selected. It should be used under the ambient temperature of 40 ℃.

2. Do not connect the compressed air inlet incorrectly. In order to facilitate the repair， a bypass pipeline shall be set to ensure the repair space. Prevent the vibration of the air compressor from being transmitted to the dryer. The weight of piping shall not be directly added to the dryer.

3. Don't stand the drain up， discount or flatten it.

4. The power supply voltage should not be less than 10%. Leakage circuit breaker with appropriate capacity shall be set. It is necessary to be grounded before use.

5. When the inlet temperature of compressed air is too high， the ambient temperature is too high (above 40 ℃)， the application flow exceeds the rated air handling capacity， the voltage is not firm by more than 10%， and the ventilation is too poor (ventilation is also required in winter， otherwise the room temperature will rise)， the protection circuit will play a role， the indicator light will be off and the operation will be interrupted.

6. When the air pressure is higher than 0.15Mpa， the drain port of the normally open automatic drain can be closed. The drainage capacity of the cold dryer is too small， the drainage outlet is open， and air is blown out.

7. The compressed air is of poor quality. If mixed with dust and oil， these dirt will adhere to the heat exchanger， reduce its operation efficiency， and the drainage is also easy to fail. It is expected to set a filter at the inlet of the dryer， and it shall be recognized that the drainage shall not be less than once a day.

8. The vent of the dryer should be cleaned with a vacuum cleaner once a month.

9. Turn on the power supply， and then turn on the compressed air after the operation is stable. After intermittent operation， it is necessary to wait for more than 3min before starting.

10. If automatic drainer is used， its drainage function shall be checked frequently. Always clean the dust on the condenser. Often check the pressure of the refrigerant to judge whether the refrigerant leaks and whether the capacity of the refrigerator has changed. Check whether the temperature of the condensate is normal.

Service reminder

1. Maintenance time of air compressor: 500 hours for the first maintenance， and every 3000 hours for future work.

2. Maintenance content of air compressor: replace the oil of air compressor and replace the internal accessories: oil filter， air filter and oil core.

3. Maintenance of air purification end: the filter element needs to be replaced for four-stage air filtration， depending on the surrounding environment. Generally， the replacement of filter element is about 6000 hours.

4. Freeze dryer: generally not required. Add refrigerant when necessary.

5. Maintenance of adsorption dryer: replace the raw material activated alumina or molecular sieve， depending on the use frequency. Generally， the replacement time is 1 to 2 years.

6. Booster equipment maintenance: regularly replace the piston ring， add grease， etc.
