The characteristics and advantages of oil-free and water-lubricated screw air compressors, Shanghai Granklin Group is engaged in the production and sales of water-lubricated air compressors, oil-free air compressors and screw air compressors.
1, reasonable structure, with ideal force balance
each side of the screw of the oil-free air compressor is equipped with a star wheel symmetrical structure, so that the oil-free air compressor not only has no unbalanced inertial force, but also the axial force and radial force used on the screw cancel each other out to make it have ideal force balance.
2, high efficiency
in theory, the oil-free air compressor has no clearance volume, large single machine capacity and ideal isothermal compression. Due to the good thermal conductivity of water, the temperature of lubricating water will drop to 45 ℃ when it is injected into the compression chamber, close to the suction temperature.
3, without oil
replacing oil with water to achieve lubrication, cooling, sealing, noise reduction and other effects, providing high-quality oil-free air, no pollution, and the discharged water does not require special treatment to meet environmental protection requirements
4. Low noise and small vibration
the superior power balance system of the oil-free air compressor can effectively suppress the vibration source, and the operation is stable. There is no special requirement for the foundation. The star wheel adopts a special customized polymer material. The working cavity is sprayed with lubricating water intermediate transmission gear, so the operating noise is low.
5, the host long life
the symmetry of the structure and the possibility of setting the flow hole make the radial and axial forces generated by the compressor work balanced, so the rotor bearing load is small and can run for 50000 hours, and the star wheel made of resin material can be used for 2-30000 hours.
Granklin oil-free lubrication screw air compressor has low maintenance cost and is widely used in health, textile printing, painting, electronic instruments, sandblasting, nitrogen production, chromatographic analysis, food processing, PTEE bottle blowing and other fields. The main features of Grantklin oil-free screw air compressor are: reasonable structure, ideal force balance; no radial and axial force during operation, only rotational force. Single-stage compression ratio is high, the shape of the structure size is small: high speed light load, easy to establish hydrodynamic lubrication.
View detailsAir compressor which brand is good? If you don't care about the price, it is certainly good to buy air compressors in Europe and America and Japan. But in the case of limited budget, the preferred domestic air compressor brand words, recommended Shanghai Granklin Group. Granklin air compressor brand, in the domestic price is still very high. Fully independent production of air compressor head, quality assurance, after-sales is also very good.
View detailsOil-free, clean, dry and hygienic gas source creates a good treatment environment for doctors and patients; lasting and stable gas source ensures the operation; low noise, energy saving, high-quality parts, reduce end customer expenses and increase service life.
Screw air compressors are increasingly used in all walks of life. Enterprises have been looking for better air compressors, hoping to purchase air compressor products with higher efficiency, fewer failures and lower maintenance rates. The oil-free air compressor produced by Shanghai Granklin Group is modular, streamlined in structure and stable in gas supply. It is a product that has won unanimous praise from users.
View detailsAir compressor, full name air compressor (English: air compressor) is the main body of the air source device. It is a device that converts the mechanical energy of the prime mover (usually an electric motor) into gas pressure energy. It is a pressure generator for compressed air. Is one of the most commonly used in industrial and mining enterprises to provide air power equipment. Usually, the air compressor is divided into screw type air compressor, piston type air compressor and so on.
The water lubricated oil-free air compressor uses pure water lubrication that meets the drinking water standard, and the entire compression process is completely free of oil. Thus, 100% oil-free clean compressed air is provided. Product features: 1. High efficiency, high reliability, 100% pure oil-free
The water-lubricated air compressor uses water to lubricate the head of the air compressor. The whole machine is made of stainless steel, and the compressed gas does not contain oil. Shanghai Granklin Group, the production of [water lubricated air compressor] in the summer is as low as possible to run [oil-free air compressor]];
Air compressor is one of the indispensable gas equipment in the production activities of enterprises, which plays a boosting role in the production process. When selecting screw air compressors, we all want to choose brand and good quality machines, so which air compressor is a good product
Before the start of the 1. operation 1. Check to confirm whether the valves of each part are in the correct position. 2. Check whether all protective devices and safety accessories are in good condition. 3. Check whether the lubricating oil level meets the standard. 2. operation steps
Air compressor is one of the main mechanical power equipment of many enterprises, and it is very necessary to maintain the safe operation of air compressor. Strict implementation of the air compressor operating procedures will not only help extend the service life of the air compressor, but also ensure the safety of the air compressor operator.
