There is a reason for the failure of permanent magnet variable frequency air compressor. When the equipment fails, we must quickly find out the cause of the failure, restore the normal operation of the machine as soon as possible, and reduce the loss of the factory.
Common faults and solutions of permanent magnet variable frequency screw air compressor:
1. air compressor loading fault
1. When the pressure exceeds the rated air pressure, there is no need to take measures to cut off the pressure regulator. When the unit operating pressure is too low, the equipment is automatically loaded.
2. Disassemble and check the solenoid valve failure, and replace it with a new one if necessary.
3. If there is leakage in the pipeline, check the pipeline and joints. If there is leakage, repair is required.
High temperature of 2. unit
1. Check the use of lubricating oil in the unit. If there is no oil or the oil level is too low, it is necessary to add oil in time.
2. Replace the oil filter when the oil filter is blocked.
3. If the oil cut-off valve fails, check that the valve core is stuck.
4. The filter element of the oil and gas separator is blocked or the resistance is too large. Clean and replace it with a new one in time.
5. Check the surface blockage of the oil cooler and clean it if necessary.
3. permanent magnet variable frequency air compressor has high fuel consumption
1. If the oil level is too high, check the oil level and drain the oil to the normal position after pressure relief.
2. Check and replace the oil.
3, the use of inferior lubricating oil.
4. Oil return pipe joint of oil and gas separator filter element is blocked and needs to be cleaned.
4. air compressor host abnormal sound
1. Remove and replace the damaged bearing.
2. Remove and replace the motor and damage the bearing.
3. Low exhaust pressure.
4. Check the connection of the equipment and deal with the leakage in time.
5. Remove the blocked air filter for cleaning or replacement.
6. Disassemble the safety valve for leakage inspection. If it is not sealed and replaced after repair.
7. There is leakage in the control pipeline between the oil-gas separator and the discharge valve.
The above are the common faults and solutions of permanent magnet variable frequency air compressor, for reference only.
The choice of air compressor with oil or without oil depends on the specific application requirements and working environment. The following are some comparisons between the two: Oil air compressor: Advantages: good lubrication effect, good cooling performance, able to withstand higher working pressure and temperature, stable operation
Answer: oil-free air compressor oil content is 0.01ppm, why the gas will still appear in the oil, we breathe in the atmosphere more or less there will be a little oil, for the human body is very, very little. On
The first maintenance of screw air compressors (first warranty) is essential to ensure the long-term stable operation of the equipment. The first service usually includes a series of inspections, adjustments and replacement of parts to ensure that the air compressor can achieve the best performance during the initial operation phase.
There is a close relationship between air compressor gas production and air consumption, but they are not completely equivalent concepts. Gas production refers to the volume of compressed air that an air compressor can produce per unit time, usually in cubic meters per minute (m & sup3;/min) or cubic English
The oil content of the compressed air of the oil-free air compressor can reach level 0. According to industry standards such as ISO 8537-1 or ISO 8573-1, Class 0 requires an oil content of less than 0.01 mg/m & sup3;, which is usually considered equivalent to the oil content grade of oil-free compressed air.
When choosing an air compressor, the question of whether to use two frequency converters or fixed frequencies actually depends on a number of factors, including use requirements, energy efficiency considerations, cost budget, and maintenance convenience. First of all, from the point of view of energy efficiency, variable frequency air compressors usually have higher energy.
Micro-oil compressed air cannot be used in the fermentation process of amino acid raw materials, and oil-free compressed air must be used. Granklin water-lubricated single screw air compressor is the preferred scheme to meet the requirements of the process. Compressed air as the core power in the fermentation process of amino acid API
How long after the air compressor is turned on, it mainly depends on the specific operation process and equipment requirements. Generally speaking, the air compressor and the cold dryer are used together, and the starting sequence and time interval between them can be adjusted according to the actual situation. The following
Screw air compressor working pressure, but a very interesting and important topic! Did you know that the pressure limit of the screw air compressor is usually between 6 and 10Bar. It's like a strong weightlifter, and while he can lift very heavy barbells, there are
In the air compressor market, the comparison between power frequency and frequency conversion screw air compressor has never stopped, so which is better, power frequency and frequency conversion screw air compressor? What is the good thing about frequency conversion screw air compressor? Insert: The main area of power frequency and frequency conversion screw air compressor
