Empty many types of air compressors. Generally speaking, we habitually divide it into oil-free screw air compressors and oil-injected air compressors. In addition to different lubricating oil methods, what is the difference between the two? When it comes to oil-free air compressors, many people's first reaction is oil-free, so do you know how oil-free screw machines work? Oil-free air compressors are usually used in food processing plants, medical machinery, textile mills and other occasions that require high quality of compressed gas. These occasions require higher oil content in the air. If the compressed air contains oil, or increase the defective rate of the product, it will also damage the gas equipment. At this time, oil-free screw air compressors are required to help production. With the development of various industries, the demand for oil-free air compressors is also increasing.
In fact, there is no difference in structure between the two. The bearings are the same. However, it works differently. The oil-free compressor does not need lubricating oil when working, and is mainly lubricated with pure water. Ordinary oil-bearing compressors pass lubricating oil and dissipate heat. Therefore, even with post-processing equipment, the compressed air will carry more or less part of the oil, so it is only suitable for some working conditions.
As we all know, air compressors generate a lot of heat during high-speed operation. If this part of the heat cannot be dispersed in time, it will cause the high temperature of the equipment. Ordinary air compressors generally need to use lubricating oil to reduce the temperature of the unit and reduce the friction of each component. So, how does the oil-free air compressor solve the high temperature problem?
The oil-free screw air compressor uses pure water or other thermally conductive materials instead of oil, which solves the high temperature problem of the compressed air compressor and enables the air compressor to operate at high speed. If the quality requirements of the compressed air produced by the enterprise are not high, we can choose ordinary screw air compressors.
A factory wants to produce at scale, such as food, which is our most common item. In the process of food production, if we still use the piston air compressor, can you still eat the food produced?
Industrial production requires high air cleanliness. Industrial air compressors need to be oil-free, water-free, and highly clean compressed air. In order to meet the production process of food and other industries.
Granklin water lubricated oil-free air compressor, through water lubrication, air compressor head operation process, do not need lubricating oil. Compressed air does not contain oil, in order to meet the modern, large-scale safety production.
This article makes a concise summary of the shortcomings of various brands of screw air compressors, which is convenient for everyone to purchase.
How much does it cost to maintain an air compressor? There are many things to refer to for the cost of one maintenance. For example, according to the degree of maintenance, air compressor maintenance itself can be divided into large maintenance, small maintenance and medium maintenance. And different air compressor brands,
The first-line brand of permanent magnet frequency conversion screw air compressor is also widely used in the industry. In order to ensure the better and stable operation of permanent magnet frequency conversion air compressor, users also need to know the daily maintenance methods of permanent magnet frequency conversion air compressor. Timely adjust the permanent magnet variable frequency air compressor
With the improvement of users' requirements for the quality of compressed air sources, oil-free air compressors are more and more widely used in some industries that require higher quality of compressed air sources, such as biology, medicine, electronics, food, medical, Automotive, chemical and other fields, requiring
The operating environment of air compressor shall be below 38 ℃. Improve the ventilation system of the air compressor room, and increase the exhaust fan in the air compressor room to discharge the hot air, thereby reducing the temperature. (Note: A heat source with high temperature cannot be placed around the air compressor) If the temperature around the machine is relatively high, the temperature sucked by the machine will be too high, so that the oil temperature and exhaust temperature will also increase accordingly. These are all needs in summer. Attention
After a period of time, the after-sales personnel of the screw air compressor will overhaul the air compressor once, replace some filter materials with short time periods of the air compressor once, and overhaul and maintain the air compressor. 1. Clean the valve, clean the valve seat, valve cover carbon deposition, cleaning
When you need "oil-free air compressor" to provide "oil-free air" for the production of enterprises, will fall into a difficult problem of choice, so many types and brands of "oil-free air compressor", pick the eye. We can look at the difference between "power frequency air compressor" and "frequency conversion air compressor" to decide how to choose and purchase. If you need "water lubricated air compressor" or "oil free air compressor" may wish to contact us "Shanghai granklin group".
Most of the ordinary energy-saving air compressors are permanent magnet variable frequency air compressors. Generally speaking, the air compressor has a great chance of running for a long time under full load, so the design capacity of the limit motor to meet the demand of the air compressor will be too large. In fact, the proportion of light load operation is very high. If an oil-free screw air compressor is used, it can be continuously adjusted according to the load, and various parameters can be kept at stable values.
The food industry has high requirements for the selection of oil-free air compressors. The oil-free air compressor used in the food industry is usually divided into non-contact, indirect contact and direct contact. No matter which one, it requires the purity and sterility of the air environment, and the reduction of microbial content is strict. Food health is directly related to the health of consumers. Once a bad air compressor is used, the impact on product quality, the threat to consumer health, and the impact on the company's reputation are very huge.
View detailsThe specific application of screw air compressor in food and pharmaceutical fields, the application of air compressor in various industries is very extensive, but the requirements of different industries for screw air compressor are also different. The application and light of screw air compressor in food and pharmaceutical fields are introduced in detail below.
