Should the CO2 gas fire extinguishing weight loss system be networked with the alarm host?

The high-pressure carbon dioxide fire extinguishing system is composed of a fire extinguishing subsystem and a fire detection and alarm subsystem, which are linked to realize the functions of automatic detection, alarm and fire extinguishing protection for the protection area.

High-pressure CO2 fire extinguishing system.

1. There are two forms of fire extinguishing system in engineering application: combined distribution system and unit independent system.

1. Combined distribution system.

High-pressure CO2 fire extinguishing system.

The combined distribution system is a fire extinguishing system in which a set of gas extinguishing agent storage devices composed of several groups of extinguishing agent bottles is selected and distributed through the pipe network to protect two or more protection areas. This method of application is relatively economical, emphasizing that there will be no fire in several protection zones at the same time.

2. Unit independent system.

High-pressure CO2 fire extinguishing system.

The unit stand-alone system is a set of gas extinguishing agent storage devices composed of several groups of extinguishing agent bottles, which protects a protective area through fixed pipes and nozzles.

Second, the main components.

1. Fire extinguishing agent bottle group.

Composition: The fire extinguishing agent bottle group is composed of a fire extinguishing agent, a container, a container valve and a weighing leak detection device.

Uses: It is usually used to store CO2 gas fire extinguishing agent, and in case of fire, the stored fire extinguishing agent is released by opening the container valve. The bottle pack has pneumatic and manual start-up functions, and has overpressure protection, false injection protection and leakage alarm functions.

Warning: The bottle group should be set up in a cool and dry place to prevent exposure to the sun and rain, to prevent collision, non-professional filling units are strictly prohibited from filling, and non-professionals are strictly forbidden to use valves.

Of course, it is necessary to network the alarm host, so that it is more convenient to transmit information between functions.

This fire extinguishing weightless system needs to be connected to the machine with a robbery device, as long as you have an alarm device networked, it can be automatically lost.

The important system of carbon dioxide gas fire extinguishing is that the host is connected to the host, and then it is also possible, but it is necessary after the networking. Consider how feasible and safe it is.

Inspection, maintenance and use of CO2 gas fire extinguishing system 1The personnel on duty carry out daily visual inspection of the whole system every day, and check whether the function of the fire extinguishing controller is normal; 2.Maintenance personnel monthly gas cylinders, pipelines, valves,

The gas fire extinguishing clock system should not be networked with the alarm host.

Law, Finance, Computer, Medicine. All are good majors, and they are all easy to employ.

It depends on what major you want to choose, and what school has accepted you.

There are many popular majors for studying in the United States, and there are countless majors with good development prospects and good salaries, but the ability and energy of international students are limited, so the choice of major has become a big problem for studying in the United States.

The choice of major to study in the United States refers to personal interests and hobbies.

The choice of major not only determines the completion of later studies, but also may affect the career planning of a lifetime, so if you do not have a clear direction, you can first consider your personal interests and personality characteristics, as well as what kind of career direction you want to engage in in the future, what industry you want to be in, whether you do academic or practical, what disciplines you are not good at, etc., and determine a general direction for yourself first.

The choice of study abroad major in the United States refers to the cost of study.

The cost of learning includes the cost of time and the cost of economy. In terms of time cost, it generally takes four years to study in the United States, but unlike China, the United States adopts a credit system, and most school students can apply for graduation as long as they complete 144 credits. There are also special majors that require five years or other years.

In the United States, the master's degree is generally two years, but the duration of business is relatively short, and the graduate students of general business majors are about one year, or even a few months. In terms of economic costs, the cost of living is mainly related to the area and personal consumption level, generally the more prosperous the area, the higher the cost of living. The main difference in economic cost is in tuition fees, which in turn is related to the cost of time.

In general, tuition at American universities is between $15,000 and $35,000 per year, and graduate school is a bit more expensive than undergraduate, with some majors being more expensive, which can be as high as $20,000 to $50,000.

Choosing a major to study in the U.S. refers to the difficulty of applying.

Generally speaking, the higher the ranking of the target institution, the more popular the major, and the larger the span with the original major, the more difficult it is to apply.

The above are the elements that need to be referred to when choosing a major to study in the United States, the choice of a major to study in the United States is not only related to the learning content in the next few years, but also related to future career development, and may even affect a lifetime.

The number of young Chinese students studying in the United States is increasing rapidly, and many Chinese students come to the United States to study finance with the dream of entering Wall Street, but the result is often disappointed. The following is an introduction to what majors are easy to find a job in the United States.

Purely academic and professional.

There are many students studying pure academic studies in China, who are difficult to give up their preferences for a certain major and deeply worried about their employment prospects on the other hand. In addition to the contradictions, they often consider going abroad to seek more outlets, but they don't know what the threshold is? Based on the previous student cases, it can be seen that different majors in the pure academic category are also different.

Physics: Relatively speaking, this is a category of majors that are easy to go abroad, and it is also relatively easy to get scholarships. However, the way out for physics students may not be much clearer than in China.

It is recommended that if students have a good foundation in mathematics and physics, they can take some finance courses at the same time, and after graduation, it is quite a good employment path to do quantitative analysis in financial institutions.

Chemistry: It's also an industry that is relatively easy to go abroad, and the job prospects in the U.S. are quite good. Among them, graduates majoring in organic chemistry have a high hope of entering large pharmaceutical companies, such as Pfizer.

However, students should pay attention to accumulating skills in various aspects during their studies, such as writing, language, and attending industry academic seminars. In addition, graduates of analytical chemistry can also go on to various pharmaceutical companies, analytical instrument companies, etc.

Biological Sciences: It's easy to go abroad, but the job opportunities can be described as "dire and dire". It is difficult to find a master's degree in biology, and it usually takes many years to work hard to become a professor after graduating from a doctorate.

After graduating from a few universities with a Ph.D. in top biology majors, you can join well-known consulting firms, such as McKinsey, BCG, etc.

Communication Engineering.

Engineering & Technology: Most students can find suitable jobs in the United States. Among them, there are many employment pathways in biomedical engineering, telecommunications and computer engineering, industrial and manufacturing engineering, mechanical engineering, chemical engineering, and petroleum, while employment in civil engineering, materials, nuclear energy, aerospace and other categories is relatively difficult.

Computer & Telecommunications Science: There are many majors in the field of computer science, and most of them have good employment prospects. Such as software, database, network, hardware, chips, wireless communications, etc., can absorb a large number of high-quality talents.

Generally, graduates with a doctoral degree go to large companies to do scientific research, and the annual salary can reach 100,000 US dollars. Graduates with a master's degree can mostly start as developers, with an annual salary of $50,000 to $80,000.

Other categories. Sociology: Acceptable job prospects. Students are reminded to pay attention to accumulating statistical skills during their studies, so that even if they can't join a consulting company after graduation, they can still find a job with solid statistics.

Accounting: It's relatively easy to find a job, but the salary in a general company is not high, about $40,000 to $50,000. If you do audit work, the salary will be slightly higher.

What major depends on your own requirements.

The following majors are available for studying in the United States:

1. Civil Engineering:

Engineering majors have always been popular among international students, and civil engineering programs in the United States are internationally renowned, and the employment rate and salary of graduates of this major are also quite optimistic. At the same time, the U.S. market is in high demand for civil engineers. According to statistics, there are currently more than 280,000 civil engineers, but they are still far from meeting the needs of society.

In addition, for students who want to return to China for development, the prospects of this major are also very good.

2. Biomedical Engineering:

With the development of the era of science and technology, the prospect of biomedical engineering is gradually on the right track. Seeing the aging of the "baby boomer" in the United States, there will be a need for more biomedical instruments on the market. At the same time, due to the wide range of applications of this profession, the employment situation in China is also good.

3. Nursing: In the United States, nursing staff have always been the best in the market. Their high employment rate and salary are often coveted by students in other majors. Especially with the aging of the population, nursing talents have entered a critical situation.

Therefore, nursing positions are often referred to as the American version of the "iron rice bowl".

4. Computer Science:

It is no secret that computer science is one of the most popular science and engineering majors in the United States. It is not difficult to see that computer science has long become a compulsory subject in all walks of life. And professional computer talents are even more promising.

5. Finance & Economics:

For students who aspire to work on Wall Street, this should be the most ideal major. In addition to the wide range of employment, the wages are also attractive. In the United States, the annual salary of people engaged in finance-related industries can generally reach more than 80,000 US dollars.
