Shanghai screw air compressor manufacturer
in Shanghai, there are many manufacturers of screw air compressors, including Shanghai Granklin (Group) Co., Ltd. The following is a detailed description of the company:
SHANGHAI GRANKRIN (GROUP) CO., LTD
product features: Focus on the production of water-lubricated oil-free air compressors. This air compressor uses water as a lubricant to ensure the purity of the compressed air. It is especially suitable for industries with extremely high air quality requirements, such as medicine, food and chemical industry.
Technological innovation: The company has successfully developed a variety of special gas compressors, such as gasoline gas compressors, nitrogen compressors, oxygen compressors, etc., demonstrating its strength in technological innovation.
Energy efficiency performance: its energy-saving permanent magnet frequency conversion oil-free air compressor with two-stage compression improves the energy efficiency of the compressor through two-stage compression technology, saving about 20% energy than one-stage compression. At the same time, the use of two-stage compression can also reduce the heat generation during the compression process and improve the volumetric efficiency of the compressed air.
Product line: In addition to the above-mentioned high-efficiency and energy-saving air compressors, Grankering also provides other types of air compressors, such as low-pressure screw air compressors and medium-pressure screw air compressors, to meet the needs of different industries and application scenarios.
Service and support: The company provides comprehensive pre-sale, in-sale and after-sales services to provide customers with professional technical support and solutions. This helps to ensure that customers are fully supported and guaranteed when selecting and using air compressors.
In summary, Shanghai Grankering (Group) Co., Ltd., as a manufacturer of water-lubricated oil-free air compressors, has shown a high level of technological innovation, product energy efficiency and service support.
The motor speed of screw air compressor varies according to the model and usage scenario. The following is the specific classification and technical analysis: 1. the standard motor speed, the rated speed of two-pole asynchronous motor is 2960 r/min (3% speed difference is allowed, and the actual range is about 2910
Screw variable frequency air compressor and permanent magnet variable frequency air compressor have their own characteristics and advantages, which is better depends on the actual needs and preferences. The following is a comparison of the characteristics of the two air compressors: screw variable frequency air compressor: can be adjusted in real time according to the actual gas consumption
Air compressors, namely air compressors, belong to the category of general machinery and equipment. It is a kind of equipment used for compressed air, which is widely used in various industrial and commercial fields. According to different compression principles and structural characteristics, air compressors can be divided into many types, such as piston air
There are obvious differences between oil-free air compressors and micro-oil air compressors in many aspects: lubrication method: oil-free air compressors do not use lubricating oil at all during the compression process, but use other lubrication methods, such as water lubrication. The micro-oil air compressor will be used in the compression process
Oil-free compressors have been designed with lubrication in mind and have been lubricated in a specific way, usually using water or other non-oil lubricants. Therefore, it may not be appropriate to apply grease on an oil-free compressor. Tools
The use method and precautions of the air compressor are the key to ensure the safe and efficient operation of the equipment. The following is a detailed description of these two aspects: Use method Preparation before starting: Check whether the parts of the air compressor are in good condition, whether the fastening bolts are loose, and the belt Or chain and other transmission parts
Air compressors are widely used in the pharmaceutical industry, and the following are their main uses: The high-pressure air generated by air compressors is a necessary condition for the stable operation of pharmaceutical equipment. For example, dry air is used to transport pharmaceutical raw materials, compressed air is used to drive pharmaceutical equipment, and
Oil-free air compressors can be divided into five categories according to lubrication methods and working principles, and their technical characteristics and application scenarios are significantly different. The following is the specific classification and analysis: 1. water lubricated oil-free air compressor principle: pure water as the lubricating medium, through the screw and star wheel rotating pressure
Confirm whether the air-cooled screw unit is frequency conversion, you can use the following methods: check the model identification: the model of the frequency conversion air-cooled screw unit usually contains the words "frequency conversion" or "BP. Observe external machine: frequency conversion air
The scroll air compressor and screw air compressor are suitable for different scenarios due to differences in structure and design, and the specific selection should be combined with the actual gas demand. Starting from the core characteristics, the following compares the two types of equipment and explains the unique advantages of Granklin water-lubricated single-screw air compressor: vortex air pressure
