There are significant differences between oil-free and oil-injection machines in many aspects:
operating principle: The oil-free machine adopts oil-free lubrication technology and will not inject oil into the air when compressing air. The fuel injection machine will inject oil into the air during the compression process to achieve gas cooling, sealing and lubrication of the rotor.
Compressed air quality: Because there is no oil injection, the quality of the compressed air is higher, and there is almost no oil stain. The fuel injection machine due to fuel injection, will make the compressed air containing oil stains, the need for post-processing devices to reduce the oil content of the gas.
Maintenance: Due to its oil-free design, the maintenance workload is relatively small. The maintenance workload of the fuel injection machine is relatively large, because the oil and filter need to be replaced regularly.
Scope of application: Oil-free machine is suitable for applications with high requirements for compressed air quality, such as food and pharmaceutical industries. The oil injection machine is suitable for applications with low requirements on compressed air quality, such as industrial fields.
Energy consumption and noise: oil-free machines are usually more energy-efficient than oil injection machines, and the operating noise is relatively low. The operating noise of the fuel injection machine is relatively high.
Cost: The initial purchase cost of an oil-free machine is usually higher than that of an oil injector, but in the long run, the total cost of ownership of an oil-free machine may be lower due to its low maintenance cost and high energy efficiency.
The explosion-proof air compressor is an air compressor specially designed for use in working environments where flammable and explosive gases or dust are present. Through specific safety design and technical measures, it prevents possible internal or external explosion events and ensures that the equipment is safe in dangerous environments.
In the food industry, in order to ensure the hygiene and safety of the production process, oil-free air compressors are usually the preferred equipment. This is because the oil-free air compressor can avoid oil pollution, ensure that the compressed air is clean and sterile, and meet the requirements of food safety. granklin, shanghai
Answer: Most of the air compressor brands are more durable, the first thing to do is to do a good job of maintenance. Water lubricated screw air compressor after years of development, good maintenance of the case is also very durable. Shanghai Grank
Condensed water will be produced during the operation of the air compressor. If it is not treated in time, it may cause equipment corrosion and compressed air quality degradation. The following is a systematic scheme for drainage treatment: the causes and hazards of 1. condensate air is compressed
Air compressors are widely used in many industries. The following are some major industries and their specific usage: Manufacturing: Air compressors are widely used in manufacturing. For example, in machining, sandblasting, steelmaking and other processes, air pressure
The 20kg air compressor is widely used in many industries. The following are some of the main industries: Automobile manufacturing industry: In the automobile manufacturing process, air compressors are used for various tasks, such as baking, painting, cleaning and assembly. 20kg of air compressor capacity
The operating range of equipment compressed air pressure fluctuations usually varies according to specific equipment and application scenarios. Generally speaking, the normal working pressure range of compressed air has a certain standard, but it may also be adjusted due to the specific needs of industrial equipment and processes.
The oil content of compressed air depends on the industry demand and equipment configuration, and is usually graded by ISO 8573-1 standard. The following is the key information: 1. oil content grade standard grade oil content (mg/m & sup3;) applicable scenario level 1 ≤ 0.
Air compressors, namely air compressors, are widely used and are mainly used in the following industries and fields: Power industry: In the power industry, air compressors are mainly used to drive various pneumatic tools and pneumatic machinery, such as control instruments, Automation devices, etc. In addition, can also
