The lubrication of oil-free screw air compressor mainly adopts water lubrication. The following is a detailed explanation on the lubrication of oil-free screw air compressor:
lubrication method:
oil-free screw air compressor mainly uses water as lubricant. In this way, the four major effects of lubrication, cooling, sealing and noise reduction are realized. Water is used to cool and lubricate the seal, which not only ensures air quality, but also allows the speed to be maintained at about 3000 rpm.
Environmental advantages:
the oil-free screw air compressor with water lubrication will not produce oil pollution during operation. The discharged water does not require special treatment and meets environmental protection requirements, which is particularly important for environmentally sensitive application scenarios.
Performance characteristics:
due to the action of water, the compression process becomes an ideal isothermal compression. The water film effect effectively prevents air leakage, so that the amount of air discharged is increased by 25% compared to a dry screw compression.
Precautions for use:
when using a water-lubricated oil-free screw air compressor, special attention should be paid to preventing the compressor from starting under pressure, setting up the compressor to protect the grounding wire, and regularly maintaining and cleaning the filter.
Applicable scene:
oil-free screw air compressors are especially suitable for areas that require high-purity compressed air, such as food, medical, and pharmaceutical industries, because these industries have strict restrictions on the oil and other pollutants in compressed air.
In summary, the water lubrication method of the oil-free screw air compressor is not only environmentally friendly but also efficient, and is especially suitable for application scenarios with high air quality requirements. During use, following the correct operation and maintenance guidelines is the key to ensuring the long life and stable performance of the machine.
When choosing an air compressor, gas consumption is a very important consideration. The following are some professional suggestions to guide you to choose the air compressor according to the air consumption, and try to use soft and professional terms to explain: determine the air consumption: first
Fermentation air quality requirements standards mainly include the following aspects: Microorganism content: microorganisms in the air (including bacteria, molds and yeasts, etc.) play an important role in the fermentation process, but their content needs to be controlled within an appropriate range to avoid
The oil-free compressor realizes oil-free lubrication through special design or materials, and its lubrication requirements mainly focus on the four cores of material selection, lubrication mode, sealing and cooling, and maintenance management. The details are as follows: 1. Material Selection: The wide application of self-lubricating materials Oil-free compressor
In the field of air compressors, oil-free air compressors have significant advantages over traditional oil-injected air compressors. Especially for the water-lubricated oil-free air compressor of Shanghai Granklin Group, its benefits are multifaceted and prominent. First, oil-free air
Air compressors are widely used in hospitals, mainly in the following aspects: 1. Operating room: In the operating room, air compressors are mainly used to drive various surgical instruments, such as electric knives, suction machines, anesthesia machines, etc. These devices require a stable and reliable gas supply
In winter, the air compressor needs to take a series of protective measures to ensure its normal operation and prolong its service life. The following are some recommended winter protection measures: Maintain proper lubrication: In winter, the decrease in temperature may cause the viscosity of the lubricating oil to increase, and the lubrication
For the question of whether protective measures need to be set up around the air compressor, this is actually a comprehensive consideration involving equipment safety, operator safety and production efficiency. First of all, from the perspective of equipment safety, the air compressor will produce vibration during operation
Companies that need to use air compressors usually involve the following industries and fields: Power industry: Air compressors are widely used in the power industry, such as compressed air systems for instruments, compressed air systems for ash removal, and compressed air systems for miscellaneous factories. These systems are
Electroplating is a process that uses the principle of electrolysis to plate a thin layer of other metals or alloys on the surface of certain metals. In this process, electroplating needs to use air compressor to provide compressed air, which has many applications in the electroplating process: control the reaction rate
Compressed air standards for industrial use focus on its cleanliness, dryness, pressure stability and other core indicators, these standards are designed to ensure the safety, stability and product quality of compressed air in various industrial applications. The following from the quality indicators, the industry should be
