Oil-free water lubrication screw air compressor has always enjoyed a high reputation in the market. The frequency conversion oil-free system selected by the device can not only reduce the oil content in the compressed air, but also be stable in use. Therefore, the correct use of oil-free air compressor has become a topic of concern to users, no matter what kind of equipment in the operation process are inevitable problems. Therefore, enterprise users need to understand the causes of various types of frequency conversion air compressor failure in time, so as to deal with it in time. The following is one of the common faults of oil free air compressor high pressure problems. The main reasons for the high working pressure of the oil-free variable frequency screw air compressor are:
1. The exhaust valve or safety cap is not sealed or leaked, which increases the suction pressure of the screw air compressor.
2. The efficiency of the compressor conveying gas is reduced, the gas transmission is reduced, the gap is increased, the sealing ring is worn too much, and the suction pressure is increased.
If the heat load of the warehouse suddenly increases, the cooling capacity of the screw air compressor is insufficient, which will cause the suction pressure to be too high.
4. The expansion valve of the system is not adjusted correctly, or the temperature sensing bag is fastened, the oil suction pipe or throttle valve is opened too much, the float valve fails or the ammonia pump system circulates too much. Cause excessive liquid supply, compressor suction pressure is too high, when the screw air compressor pressure is too high or too low, you must promptly check whether the intake valve is fully open, whether the current is in the normal range, the external useful air volume, whether there is air leakage, etc.
At present, many users will be online oil-free screw air compressor, we must verify the manufacturer's brand and qualification when buying online. When it comes to money issues, don't trust the seller's excuses and rhetoric. You should examine the comprehensive strength of the selected manufacturers in many ways, choose manufacturers with guaranteed quality and high after-sales service quality, and after determining the air compressor model, Sign a formal contract so as to guarantee our rights and interests.
Granklin water-lubricated air compressor has obtained a number of certifications to ensure that the gas provided is 100% oil-free, and the compressed air provided to users to meet the needs of users for high-quality air sources. If there is no local after-sales service center or entrusted distributor, you can directly contact the head office for warranty service.
When Xiao Chen purchased the screw air compressor for the company, he hesitated between "power frequency air compressor" and "frequency conversion air compressor" because Xiao Chen did not know the difference between the two. According to Xiao Chen's description, Xiao Shen of Shanghai granklin group recommended "power frequency air compressor" to Xiao Chen. why not recommend "permanent magnet frequency air compressor" and mainly push "power frequency air compressor?
The filter elements of the air compressor include air filter, oil filter and oil filter. The three perform their respective duties and play different roles. Any failure of the filter element may cause problems in the operation of the air compressor. Today we will talk about the three filter elements of the air compressor. The air filter element and oil filter element of the air compressor are made of high-precision filter paper. Under normal circumstances, the service life is about 2000 hours. The filter element must be replaced as soon as possible to avoid damage to the host.

Select the air compressor manufacturer quotation, the first choice of qualified air compressor manufacturers, the factory in the after-sales service and technical support is not the same. Most large-scale projects such as chemical manufacturing and medical equipment production will choose to find "Shanghai Granklin Group" and communicate with sales and technical departments to adopt appropriate technical solutions.
View detailsThe screw air compressor needs to be drained every once in a while, which is recognized by the industry. Even so, there will still be users will ask, do not drain, what will happen? Today we will answer this part of the user's questions. Undrained will first lead
Common types of oil-free compressor are: oil-free scroll air compressor, dry oil-free air compressor, water lubrication oil-free air compressor. Different oil-free screw air compressor models, exhaust pressure, power and exhaust volume parameters are different. The medical water-lubricated air compressor produced by Shanghai Granklin Group is 100% oil-free.
View detailsThe common faults of screw air compressor are: insufficient exhaust, abnormal pressure, abnormal start, high temperature and even combustion. During daily operation and use, impurities and dust in the air enter the air compressor, or the parts of the air compressor are worn, which will cause
For the screw air compressor should be how to select, you first need to know the work flow of the screw air compressor, and then determine how to select. Generally speaking, there are three steps:(1) first determine the working pressure;(2) then set the corresponding volume flow;(3) finally, the power supply capacity. Selection of working pressure (exhaust pressure):
Generally, there are relevant installation manuals for the installation of mechanical equipment. The same is true for silent oil-free air compressors. Whether the environmental quality is good or not, the silent oil-free air compressors need to pay attention to the installation environment and whether it affects the installation effect. need in sufficient light
