Oil-free screw air compressors are divided into two types, one is a dry oil-free screw air compressor, and the other is a water lubricated oil-free screw air compressor.
1. dry oil-free screw air compressor is also called oil-free screw air compressor, mostly twin screw air compressor, which means that only air is absorbed in the rotor, and the lubrication and sealing of the rotor are carried out by brushing the coating on the surface of the rotor teeth. The power range of dry screw air compressors sold in China is generally 15-900kw.
① There are two kinds of coatings, one is Teflon with general performance, and the other is a lot of molybdenum disulfide. No matter which one of the above, it has a service life and has a high requirement for water. Therefore, this kind of oil-free screw machine needs to rotate the machine frequently when not in use, so as to avoid the machine from being stuck due to the long-term immobility of the main machine. The frequent occurrence of host card failure is caused by such reasons. The main engine exhaust temperature is very high, the main engine exhaust temperature of the general oil-free screw machine can reach 180 +, the general factory will do some protective measures before leaving the factory, but in the operation or pay special attention to high temperature parts, so as not to cause burns and even fire danger.
At present, except for the oil-free mainframe maintenance proposed by IR, other manufacturers require direct replacement of the mainframe, and the cost of replacing the mainframe is very high.
2. water-lubricated oil-free screw air compressor is also called water-jet screw air compressor, that is, screw air compressor, there are also twin-screw air compressors, which means that while air is sucked in in the rotor chamber, water is also sucked in (the role of lubricating the rotor and sealing) to mix water and air and compress it.
① Water-lubricated oil-free air compressor is generally screw air compressor, screw water-lubricated oil-free air compressor is characterized by the use of water as a compressor lubrication medium is water, water-based as a seal, completely oil-free, pure oil-free compressed air, completely changed the production environment of some industries.
Because it is to the compression cavity spray water, the temperature is only about 40-50 degrees, constant temperature compression, volume efficiency is higher, than the dry oil-free screw air compressor efficiency increased by 15%.
The maintenance cost of oil-free water lubrication screw air compressor is low, only need to replace the water, water filter, air filter.
Water lubricated oil-free screw air compressor brand which? The market's numerous water lubricated oil-free screw air compressor merchants make many customers dazzled, really want to pick out an efficient, high-quality, affordable water lubricated oil-free screw air compressor in a short period of time is really not an easy thing, especially for many of the first time to buy water lubricated oil-free screw air compressor customers, the first time to buy oil-free screw air compressor is more.
Although the saying goes: foreign river chanting, but from the right time, right place, with right people. and other aspects, the local oil-free screw air compressor has a more competitive advantage. Which domestic oil-free screw air compressor? First of all, we have to ask, which domestic water-lubricated oil-free screw air compressor brands? At present, China's enterprises producing water-lubricated screw air compressors are doing relatively well, and the Granklin air compressor produced by Shanghai Granklin Group has a good reputation.
Customers have the most say, users have the most right to defend. Product quality is the most important, and corporate reputation accounts for a large proportion. This is also the reference standard for customers when selecting oil-free screw air compressors. From the product quality, corporate reputation, market evaluation and other aspects for reference, Shanghai Granklin Group is an enterprise specializing in lubricating screw air compressors. The water-lubricated screw air compressors we produce are 100% oil-free.
Many friends want to buy "good" gas tank, good gas tank should be how to distinguish? Here are a few comments for a few points, for your reference:
The oil-free and water-lubricated single-screw compressors produced by Shanghai Granklin Group have unparalleled advantages in terms of gas quality, energy saving, easy maintenance and reliability, and are widely used in food and beverage, medicine and medical care, and precision manufacturing., Instrumentation, fuel cells, microelectronics, biology and other industries with extremely high gas demand.
View detailsWhen choosing an air compressor, when transitioning from an oil-injected screw air compressor to an "oil-free screw air compressor", we will always have doubts about unknown products that we do not understand ". After all, air compressor family after years of development, has produced many kinds of compressor. The "water-lubricated screw air compressor" produced by Shanghai Granklin Group is one of the "oil-free screw air compressors.
A large amount of condensed water will be produced during the working process of the air compressor, which must be discharged in time in order not to affect the normal operation of the unit. There are two main ways of condensate discharge, manual discharge and automatic discharge. Manual discharge has a disadvantage. If the staff forgets to discharge, it will lead
If the maintenance of the air compressor is not timely, it will have a great impact on the air compressor. The screw air compressor will have a first guarantee for 500 hours of operation and a maintenance for 2000 hours after operation. Screw air compressor oil is good or bad on the oil injection screw
A good brand of domestic oil-free air compressor, Shanghai granklin group provides you with a quotation for oil-free screw air compressor, which is a high-quality product and brand in the domestic air compressor industry. we sincerely invite peers who want to act as agents for oil-free air compressor and win-win cooperation.
View detailsThe gas supply pressure required by the glass industry is relatively small. If the conventional air compressor on the market is used, it will cause a waste of resources. The conventional pressure on the market is 0.7-1.0mpa, and the glass industry is 0.3-0.5mpa. This requires accurate selection during selection without wasting too much energy consumption. When your air pressure is 0.2 -- 0
The oil-free screw compressor produced by Shanghai Granklin Group provides pure compressed gas to prevent bacteria and bacteriophages from breeding in the gas. In the electroplating industry, there are some problems in the production process, such as the surface of the coating, burning, cracks and so on. People use stirring to solve such problems, and the stirring needs the support of compressed air.
View detailsFood companies should consider the impact of various potential risks, if the use of 100 oil-free compressor, can minimize the potential risk of compressed air from the air compressor, to provide protection for enterprise production. Finally, food companies must ensure that compressed air systems are safe for the health of consumers. Consumers pay great attention to the safety of the purchased food, so in the production process, all operations with the air compression system should be recorded to avoid unnecessary trouble!
Oil-free air compressors are often used in production and life. Many companies will purchase them, but there are some parameters that need to be understood when purchasing. The precautions for choosing oil-free air compressors are as follows: 1: First of all, you must choose a truly oil-free air compressor. There are many types of oil-free air compressors on the market, but there are not many that can be completely oil-free, granklin water lubricated air compressor when running
