Compressed air is ubiquitous in modern industry. Electronics, medicine, food, chemical and many other fields have high requirements for the quality of compressed air, requiring pure oil-free and dust-free compressed air. Water-jet screw oil-free air compressor is an emerging technology. It has attracted people's attention with many characteristics. The role of water in the water jet screw is cooling, sealing, and lubrication. Compared with the dry oil-free screw compressor, it has low compression temperature, small internal leakage, and high compression efficiency. Due to the action of water, the operation noise of the water spray screw is very low. If the water lubricated bearings are used again, the quality of oil-free compressed air can be guaranteed.
But it is also because of the water, food, medical users will worry about whether there will be microorganisms in the compressed air. So the water screw has such a risk?
Before answering this question, we need to understand the living conditions of microorganisms. The survival and reproduction of microorganisms requires several conditions: nutrition, temperature, pH, oxygen content, moisture, radiation, etc. Two conditions of temperature and moisture are involved in the compressor. Then look at the two conditions of the compressor is suitable for the growth and reproduction of microorganisms.
Temperature: Environmental microorganisms can be divided into three categories: low-temperature microorganisms, medium-temperature microorganisms and high-temperature microorganisms according to their growth temperature range. Their survival temperatures are -12~30°C,10~45°C and 25~70°C, respectively. High-temperature microorganisms are suitable for growing at temperatures above 45-50°C, and their distribution in nature is limited to certain areas, such as hot springs, sunny soil surface, compost, fermented feed and other decaying organic matter, such as compost. The temperature can reach 60-70°C. Pasteurization is to use 62~65 degrees or 75-90 degrees can kill 99% of the microorganisms in food.
The water-jet compressor evaluated the risk of microbial survival by simulation tests. Although there is water in the air compressor and the temperature is about 60°C, the microorganisms will die in the running compressor when they are under pressure due to the compressor conditions (temperature, pressure). It can be seen from the air produced by the compressor that even under the condition of serious water pollution, no microorganisms remain in the discharged air.
Need to purchase water lubricated oil-free screw air compressor can contact us, contact phone number: 18964858538, we will provide you with suitable compressed air solutions.
Water lubricated screw air compressor host, water vapor cylinder, water filter and air filter, intake valve, cold dryer, air storage tank, etc. are integrated into one, forming an integrated air compressor system. The built-in three filters are easy to maintain, and there is no pipeline loss inside. It takes up very little space and is the key first step in forming a small lightweight air compressor; at the same time, it also provides
Compressors are classified according to different structural forms as follows: According to their principles, they can be divided into: reciprocating (piston) compressors, rotary (rotary) compressors (turbine, water ring, turbine) compressors, and axial flow Compressors, jet compressors and screw compression
I believe everyone has experienced the air compressor host or motor overload, maybe it is a small problem for you, maybe you are troubled by this fault. The reasons for the failure are: 1. The voltage is too low: the rated working voltage of the general compressor is 380V, and the upper and lower levels are allowed to float at about 5%.
Oil-free air compressor to choose domestic, inexpensive, more after-sales service on an insurance. Domestic oil-free air compressors are getting better and better. The sales of mature and stable products in the domestic market are also increasing year by year. Domestic industrialization is also constantly upgrading and updating, in order to meet the demand for gas. The oil-free air compressor (full name: water-lubricated oil-free air compressor) produced by Shanghai Granklin Group is also increasing in sales in the domestic market.
1. The possibility of the screw air compressor failing to start the air compressor failing to start causes this problem is much more likely than price, but experienced engineers generally consider the problem from the following aspects: First, whether the fuse is burned out, this is a common question.
Screw air compressor consumes a lot of electricity in the whole factory. Guangzhou screw air compressor manufacturers can greatly reduce the cost of the factory by converting part of the consumption of screw air compressor into renewable energy. For example, the condensate recovery of screw air compressor, Guangzhou screw air compressor manufacturers collect the heat energy of screw air compressor through other equipment for everyone to take a bath, etc. This equipment is the condensate recovery equipment.
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.
If you determine the size and type of compressor, but there is a problem is the choice of oil lubrication or oil-free air compressor. In order not to make the answer too complicated, your choice should be based on the application of compressed air. Do I need an oil-free compressor?
When 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.
Users who use screw air compressors often complain about the accumulation of water in the head of the air compressor, and some even appear on the new screw air compressor that has just been used for a short time, causing the head of the screw machine of the air compressor to rust or even get stuck and damaged, and losing money and time.
