1. depends on the qualification of manufacturing enterprises. A strong brand-name enterprise, the qualification and honor is not ordinary enterprises can be compared. Although some small enterprises have the manufacturing license of pressure vessels, the overall equipment is old and the management is not very standardized. The gas storage tanks produced are prone to potential safety hazards. Therefore, the general users should buy them. It is best to have a more comprehensive understanding of the various qualifications of the enterprise so as to avoid unnecessary troubles.
2. look at the appearance. The appearance of the product reflects its grade and value. Only the formal and powerful manufacturers have advanced equipment guarantee and good quality assurance system to ensure the appearance of the product. The trademark of a high-quality gas tank is very obvious, and the brand of the gas tank can be clearly known 50 meters away from the gas tank. Approaching the gas storage tank, the tank itself is bright in color, uniform in surface treatment, flat welds and clear lines, so it is best to buy newly produced products.
3. look at the product nameplate. The nameplate should indicate the name and production date of the production enterprise and supervision and inspection unit, whether there is a seal of the supervision and inspection unit in the upper right corner of the nameplate, and the nameplate must indicate the product number, weight, volume size, maximum pressure and working pressure to bear and the pressure of hydraulic test, as well as the medium of the gas storage tank, and the steel seal number of the product must be indicated directly below the nameplate of the whole tank, moreover, the stamp number and the number on the nameplate must be consistent. If the two numbers are found to be inconsistent, it is best not to buy them.
4. look at the quality guarantee. According to the relevant regulations of the state, each gas storage tank must be equipped with a quality guarantee. The quality guarantee is an important certificate to prove that the gas storage tank is qualified. If there is no quality guarantee, even if the gas storage tank is cheap, in order to ensure the safety of use, users are advised not to buy it.
5. should choose large enterprises, well-known brands of products. The products of these enterprises not only strictly implement the GB150-98 "steel pressure vessel" standard, but also form their own enterprise standards. At the same time, the products of these enterprises have advanced production equipment, strict production process management and good quality of raw materials. Although the price of these companies' products may be relatively expensive, they can guarantee the products when they are used and can be used with confidence. In addition, through a variety of quality system certification of the enterprise production of products is also the focus.
Shanghai granklin group has many cases in the food industry. food factories that need oil-free screw air compressor can contact us for inquiry. In recent years, the food industry has developed rapidly, and the automation level of food factory equipment has also been continuously improved. Machine, electricity, gas and other integrated technologies are increasingly applied to the food industry, oil-free screw air compressor is one of them.
View detailsStructural aspect: The twin-screw air compressor has few moving parts and simple structure. The rigidity of the male rotor is higher than that of the female rotor, but the male rotor also bears most of the load. The rigid load ratio of the male and female rotors is close, the deformation is uniform, and the volume coefficient is high. The single screw air compressor has three rotating shafts
Screw air compressor has the characteristics of simple structure, small size and light weight. It has continuous exhaust, small exhaust pulsation, small vibration, and low requirements for installation foundation; few wearing parts, convenient use and maintenance; compact structure and stability Good, reliable operation, long life
It is very difficult to make a brand, from the brand name to the registered brand, as well as the design of the product LOGO. The most important thing is whether the products to be produced by the enterprise have enough technology accumulation to complete the quantitative change and qualitative change of the enterprise brand. Shanghai granklin group in continuous research and development of products, improve products at the same time there are various patent certificates, such as all kinds of "water lubricated oil-free air compressor" certification, in the air compressor brand we have always been serious, dare not have the slightest slack.
View detailsThe food industry has high requirements for the selection of oil-free air compressors. The oil-free air compressor used in the food industry is usually divided into non-contact, indirect contact and direct contact. No matter which one, it requires the purity and sterility of the air environment, and the reduction of microbial content is strict. Food health is directly related to the health of consumers. Once a bad air compressor is used, the impact on product quality, the threat to consumer health, and the impact on the company's reputation are very huge.
View detailsWith the blockade of China's high-tech technology and equipment by the United States in recent years, such as the recent mention of advanced technology and equipment used in the semiconductor and chip industries: Japan's Shin-Yue, the United States Dow, Asmai, etc. However, the realization of the semiconductor and chip industry's gradual national
In the field of oil-free air compressor, there is also an air compressor called water-lubricated oil-free air compressor, water-lubricated oil-free screw air compressor, which uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil participation. Therefore, what is provided is 100% oil-free
It is understood that the use of screw air compressor users more or less, or large or small are almost experienced host or motor overload. When the screw air compressor is running under unloading conditions, its energy consumption rating is 30%-40%. The energy saving effect of permanent magnet motor is better than that of power frequency and ordinary frequency conversion in the case of low load.
In the compressed air industry, one of the most important developments is the use of oil-filled and oil-free air compressors. Each has advantages, depending on the application. Both are major markets. A key difference is that oil-free compressors are not as easy as oil-injected compressors.
What are the functions and functions of the screw air compressor control panel (1) Basic operation buttons: 1) Start. Start the air compressor under normal working conditions. 2) Stop. Stop the air compressor under normal working conditions
