Recently, we have seen more and more air compressor brands on the market, so that many customers have no choice, how to choose? What brand of screw air compressor is better? Xiaobian thinks: what brand of screw air compressor to choose is not important, the important thing is to start from the needs of customers. If the user needs an affordable screw air compressor, there are no too strict regulations on product requirements, and you can choose a relatively well-known brand on the market. If the customer wants the product quality and the company's perfect screw air compressor, you need to choose some well-known screw air compressor brands, because the brand is well-known because of the use of more people, and most people can be recognized as the leading brand of the screw air compressor industry.
　　
　　Xiaobian warm reminder, when choosing a screw air compressor for your company, you need to pay attention to:
　　
　　1. The air consumption of the company's production line corresponds to the exhaust volume of the screw air compressor;
　　
　　2. According to the corresponding exhaust volume of the screw air compressor, choose the appropriate power;
　　
　　3. Because the installation of air compressors also needs to pay attention to the laying of pipelines, the larger the pipeline passage, the fewer turning points, and the less loss. 　　Common faults and solutions:
　　
　　1. Jumping caused by excessive temperature of the head: due to the high ambient temperature caused by jumping, it is necessary to improve the ambient temperature and reduce the ambient temperature by reasonably improving the ventilation device; The lubricating oil level is abnormal, and the lubricating oil level is normal through the standard; The temperature difference of the oil cooler is not normal, check the oil cooler, the temperature difference between the lubricating oil before and after the oil cooler should be about 18 °C, if the temperature difference is too low, the oil cooler should be cleaned, if the temperature difference is too high, it means that too little lubricating oil passes through the cooler, and the oil circuit should be checked whether it is blocked: the oil is blocked, replace the oil concern; Check whether the thermostatic valve is working properly; Check whether the oil shut-off valve is working normally; If the temperature is too high during unloading, check whether the control gas path of the oil is leaking, causing the base oil pressure to be too low.
　　
　　2. High oil content at the outlet (under normal working conditions: 2-3PPM): first of all, the exhaust pressure of the air compressor shall not be lower than 4Bar; Using paper cups or glasses for sampling judgment, it is normal to have scattered oil sprays on the water surface, and if there is oil-water stratification, the oil content is too high; Check whether the oil level is too high and whether the lubricating oil is too dirty; Check whether the oil return pipe is blocked, eccentric, and too short; Check whether the check valve in the return pipe is stuck or reversed; Check whether the oil return hose to the bottom of the rotor is unblocked; Check whether the oil and gas separator shroud is damaged; Check the oil and gas separator for breakage.
　　
　　3. The lubricating oil of the oil-injected screw machine contains water: the unit is unloaded for a long time, the air consumption is adjusted, and the loading time of the air compressor is increased; Thermostatic valve failure, thermostatic valve maintenance or replacement; The cooling water temperature is too low, avoid using chilled water; Water cooler leakage, repair or replacement of water cooler.
　　
　　4. High oil content at the outlet of the machine head: the oil level is too high, and the oil is put to the standard height; If the oil temperature is too high, check the temperature control valve, cooling water, cooling water pressure, oil cooling efficiency; The 2mm small hole of the oil return pipe is blocked and dredged; The return pipe is bent or deviated, adjusted or replaced by the return pipe; The oil and gas separator is damaged, replace the oil and gas separator.
　　
　　5. The air compressor does not load: the solenoid valve action is a mechanical failure, determine whether 10% of the control gas exists, if it exists, it is the unloading valve failure, and the unloading valve is maintained. If it does not exist, check whether the minimum pressure valve is leaking, whether the air pipe is blocked or leaking; If the solenoid valve does not operate, it is an electrical failure, the solenoid valve is damaged, the solenoid valve is repaired, or the contact is poor and reconnected.
