The choice of medical air compressor is one of dry oil-free air compressor and water lubricated oil-free air compressor, which scheme will be better.
I need to talk about the advantages and disadvantages of the two schemes in order to better choose a suitable medical air compressor.
the advantages and disadvantages of dry oil free screw air compressor:
advantages: it has been put into the market for nearly half a century, and most of the imported brands have been relatively mature.
Disadvantages: As the technology has been relatively long, the congenital technical defects existing in itself cannot be changed (the structure of the whole machine is complex, the rotating speed of the main engine is as high as 9000~18000 r/min minutes, the working temperature of the main engine is as high as 200 degrees, the main engine has large leakage, large noise, low efficiency, high energy consumption, complicated operation and high maintenance cost).
the advantages and disadvantages of water lubricated oil free screw machine:
advantages: After summarizing the congenital structural design defects of the dry oil-free screw compressor, the advanced oil-free screw compressor technology developed and put into the market in the past ten years. The host and piping system are made of 304 stainless steel or copper alloy. The main engine speed is 2980 r/min minutes, the main engine working temperature is less than 50 degrees, the water sealing efficiency is high, the operation and maintenance is simple, the maintenance cost is low, and the noise is low.
Disadvantages: some water lubrication host shell using copper alloy material, corrosion resistance is poor. Although advanced water lubrication technology is also the main development direction of oil-free screw compressors, a large amount of capital has poured into this industry, resulting in a large number of low-quality immature products flowing into the market in the past two years, causing unnecessary losses to users.
In the choice of air compressor, to meet the requirements of the project as the first, easy maintenance, low failure, high cleanliness of compressed gas.
The medical industry must not have any sloppy, water lubricated air compressor in the forefront of air cleanliness, for the country's medical, chemical, food and other high gas requirements of the industry to provide oil-free air.
1. Air compressor maintenance personnel shall deal with the recent operation of the machine and the corresponding problems according to the crew's reflection; 2. Air compressor maintenance Check whether there is water leakage, air leakage and oil leakage in the air pressure system, and stop the machine for maintenance if necessary; 3. Check the normal drainage of the automatic drainage device, air storage cylinder, dryer and filter of the air compressor when overhauling the air compressor. Whether the discharged water is in normal condition, and if there is blockage and flying oil, deal with the relevant components;
View detailsThe structure is reasonable and has ideal force balance: the screw of the oil-free air compressor is equipped with a star wheel symmetrical structure on both sides, so that the oil-free air compressor not only has no unbalanced inertial force, but also uses the axial force on the screw. The radial force also cancels each other out, making it ideal
There is a complete set of procedures for the installation of screw air compressors. Although the standards of various manufacturers are different, the general steps are similar. On the basis of summarizing the installation and debugging experience of many air compressors, the author now writes down the general steps and matters needing attention in an article to provide reference for peers to smoothly carry out the installation and debugging of air compressors.
Shanghai Granklin Group produces water-lubricated air compressor series products, including water-lubricated permanent magnet variable frequency air compressor and water-lubricated power frequency air compressor. From 5.5KW-250KW models have production, you can call at any time to customize your needs. In the process of continuous gas consumption, the permanent magnet frequency conversion air compressor is actually not much different from the power frequency air compressor, so when the gas consumption reaches a certain value, the permanent magnet frequency conversion air compressor is used together with the power frequency air compressor, which can well reduce the energy consumption of the enterprise.
Buy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
Choosing among different types of air compressors is a relatively difficult problem. Here are the advantages and disadvantages of "oil-free scroll air compressor" and "screw air compressor" for your reference. If you need to purchase "water lubricated air compressor" can contact us [Shanghai granklin group], we are a professional manufacturer of "oil free air compressor.
What are the brands of air compressors? Manufacturers that can produce air compressors, there are many large overseas factories and small factories, and there are at least thousands of domestic screw air compressor manufacturers. Do a good screw air compressor brand has
As a commonly used power source in factories, air compressors mainly supply pneumatic valves, instruments, cylinders and other equipment to provide effective protection for the normal operation of production. However, the air compressor system often has some problems, and even seriously affect the production. In this paper, some snail
For customers who need to save electricity and energy consumption, how to spend less money to buy a good quality oil-free permanent magnet air compressor and reduce the energy consumption expenditure of enterprises is the concern of users. So how much does it cost to buy an air compressor?
[Structure diagram of single screw compressor] [Figure [Analysis Single screw air compressor belongs to positive displacement compressor. By compressing the gas in a variable volume, the volume of this part is reduced and the pressure is increased. The core structure of the compressor is finished by a special machine tool and consists of a screw with six spiral grooves, with one on both sides.
