What Is a Compressor Pressure Switch?

Compressor ^[1] (compressor) is a driven fluid machine that promotes low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. It sucks low-temperature and low-pressure refrigerant gas from the suction pipe, compresses the piston by running the motor, and then discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle.

The compressor is seen as

The compressor can be divided according to its principle ^[3]

Compressor accessories are as follows ^[4]

The specifications of the compressor are

The first load operation of the compressor was in an empty car

The compressor is

With the development of industry, the pollution to the earth is becoming more and more serious. Environmental protection has become an important issue of global concern. Preventing the destruction of the atmospheric ozone layer and

The compressor capacity should be determined according to the total mechanical load of each evaporation temperature system multiplied by the operating time coefficient. Except for special requirements, equipment is generally not used. ^[11]

How to distinguish new compressors from old compressors or refurbished compressors. In fact, this is the same as the RMB identification method, which requires some expertise ^[13]

Absolute pressure ^[14]

"The next ten years will be a crucial period for China to transform from a manufacturing country to a manufacturing power, and realize the transformation from Chinese manufacturing to Chinese creation and Chinese manufacturing ^[1] .

Linear compressor technology replaces traditional compressors because of its high efficiency, zero noise, zero pollution, and simple structure. It is a truly green industrial technology.

Six manifestations of the development of China's manufacturing industry in the next ten years

First, manufacturing has become the backbone of China's national economy. The added value of the manufacturing industry accounts for about one-third of the country's GDP and 80% of all industries; taxes paid account for 90% of all industries; exports of manufactured goods account for 90% of total national foreign trade exports; 90% of all industries. "From the perspective of development trends, there will be some changes in the next ten years, but manufacturing will still occupy a relatively important position in the national economy."

Second, China's manufacturing industry will maintain a certain rate of growth in the next ten years.

Third, the total volume and scale of China's manufacturing industry has ranked first in the world, and it will rank first in the world in the next ten years.

Fourth, transformation and upgrading and structural adjustment will be the main theme of China's manufacturing industry in the next decade. China's manufacturing industry will face five major changes in the future: namely, the transformation from relying on investment to relying mainly on technological progress and improving the quality of workers; from the focus on expansion of production capacity to the accumulation of technology capacity; from production-oriented manufacturing to service-oriented manufacturing ; From the low end of the world manufacturing value chain to the high end of the world manufacturing value chain; from the squeeze on the environment to the environmentally friendly transition.

Fifth, the integration of information technology and China's manufacturing industry is moving forward in depth and breadth. Integration of informatization and industrialization ... "Informatization of manufacturing is the focus and convergence point of the integration of the two industries." The integration of manufacturing with information technology and high technology can promote the transformation and upgrading of traditional manufacturing to modern manufacturing. Among them, intelligence is very important: the realization of digitalization of products and equipment is to provide intelligent tools to various sectors of the national economy, thereby improving the level of social productivity in China and increasing the international competitiveness of China's equipment manufacturing industry. The research centers in this field include the National Independent Third-Party Research Center for Major Technical Equipment-China National Major Machinery and Equipment Network.

Sixth, green manufacturing, intelligent manufacturing, and service-oriented manufacturing will become the direction of China's manufacturing industry. Green manufacturing is the concept of green in our manufacturing products and the entire life cycle, from design, production to remanufacturing. For example, develop energy-saving products, energy-saving technologies, and energy-saving processes; develop products and processes with less pollution, no pollution, and low emissions; promote low-carbon development and a circular economy; reduce resource consumption and save resources; and protect the ecology. Intelligent manufacturing systems will eventually shift from a human-machine harmonious system with human beings as the main decision-making core to autonomous operation with machines as the mainstay.

For example, the development of intelligent products (smart machine tools); the automation and intelligence of the production process; the development of industrial automatic control technologies and products (sensor elements, automation instruments, PLC, DCS, FCS, fieldbus, numerical control systems), remote monitoring, testing , Diagnosis, etc. Observing the development trend of the industry in the past year, the compressor companies have changed a lot. Whether from the sales channel or the internal management of the company, reforms have been made. This is also the main reason for the rapid recovery of compressor companies.
