Air compressors are used in various production fields. Due to the different quality of equipment, they will be reported for repair more or less. Common faults mainly include high-temperature shutdown, frequent loading and unloading, and failure to start when the voltage is too high. When the air compressor fails, many users often do not know how to deal with it. The following summarizes the countermeasures that the pressure of the screw air compressor is too high to start and the voltage is too low.
1, the voltage is too high to start
screw air compressor units are equipped with voltage protection devices, general equipment low-voltage automatic start, high-voltage automatic shutdown is a normal phenomenon. Pressure-related are automatically controlled by pressure switches or pressure sensors. Therefore, if the machine has a pressure problem, it is generally only necessary to adjust the pressure of the air compressor, adjust the action range of the pressure switch and the starting pressure set on the sensor. The pressure switch has a RANGE and DIFFE. Adjust range according to the production needs of the enterprise, diffe generally does not move. Adjust the start-stop pressure value set by the pressure sensor. The pressure setting selection can be found on the air compressor panel for adjustment.
2. The voltage is too low
this is a problem that many users are prone to, and the harm is often greater. If an enterprise uses a power frequency air compressor, the voltage can only be changed by adjusting the transformer. For example, if the power grid voltage is only 360V, then the transformer needs to be replaced from 380V to 220V. However, as the cost of replacing the transformer for the motor is often high, it is recommended to consult the manufacturer's motor whether it can afford it, and then decide on the subsequent method.
If it is frequency conversion air compressor solution is more. For variable frequency models, due to the internal circuit principle of the inverter: the inverter changes the output power by changing the output voltage, but this voltage cannot be higher than the input voltage. if,
the input voltage is only 360V, then a 380V rated voltage machine can only output to 360V, the voltage is not enough, the inverter will raise the current. In fact, as long as the current is not too large, it can also be used. If the current is too large, the upper limit frequency can also be reduced to ensure the normal operation of the machine.
Screw air compressor in the use of the process of failure is inevitable, only to master the basic fault handling methods to ensure the normal operation of the unit.
Shanghai granklin group produces water-lubricated air compressors, which use water-lubricated air compressor heads. The whole air compressor does not contain oil, and the following problems with oil screw air compressors will not occur.
View detailsBuy products preferred big brand, good service quality manufacturers. From foreign to domestic, there are only a few enterprises that can make water-lubricated air compressors in the screw air compressor industry. "Shanghai granklin Group" is one of them. granklin Do not forget your initiative mind strove forward on the road of water-lubricated air compressors.
There are many types of air compressors, and they are generally subconsciously divided into oil-free screw air compressors and oil-free air compressors. This two in addition to the lubricating oil method is not the same as what is not the same? Mentioned oil-free air compressor many people's first reaction is not oil,
The "water-lubricated oil-free air compressor" produced by Shanghai Granklin Group is widely used in all aspects of the medical industry. The "medical air compressor" cannot tolerate a trace of carelessness, and the exhaust must be oil-free.
Where there is a screw air compressor in Guangzhou, where there is a screw compressor in Guangzhou to buy in the air, because of the factors of airflow and strong wind, where there is a screw air compressor in Guangzhou, the air always contains different degrees of dust, lime sand and other impurities.
The water-lubricated oil-free air compressor produced by Shanghai Granklin Group adopts single-screw technology to replace oil with water to achieve lubrication, cooling, sealing, noise reduction and other effects, providing high-quality oil-free air, no pollution, and the discharged water No special treatment is required to meet environmental protection requirements.
Shanghai Granklin Group produces water-lubricated air compressors. Water-lubricated air compressors do not use lubricating oil. Water is used as a lubricant with less pollution, better environmental protection and cleaner exhaust gas. Today's society promotes environmentally friendly travel. If the distance to work is not too far, more and more people choose to walk and ride bicycles as their main mode of travel. Environmental protection is the eternal theme of life. A high-quality environmental protection air compressor will bring convenience and quickness to your work.
View detailsThe variable frequency air compressor adopts variable frequency speed regulation, the permanent magnet synchronous motor has good efficiency, high power factor, wide efficiency range, which can ensure extremely high operating efficiency and greatly improve the power saving rate in the entire speed regulation range. The permanent magnet synchronous motor (PMSM) runs with low noise. Air compressor frequency conversion
Speaking of how much is the water-lubricated oil-free air compressor? This problem, granklin's Shen is a professional counterpart. The main product of our Granklin Group is the water-lubricated oil-free air compressor. Under this topic, Granklin Group, as a senior enterprise in the industry, still has a little experience.
Air compressors that can be used in medical systems need to be oil-free, and the air cannot contain any grease. In the production process of medicines and medical devices, air products containing oil and gas are unqualified.
