Check Method for Self-start and Stop Problems Found by Permanent Magnet Variable Frequency Air Compressor?
1. Electrical parts:
the permanent magnet variable frequency air compressor suddenly stops during operation. First check whether there is a fault prompt, and check if there is a fault prompt. If it does not continue to start, check the reason. When using an air compressor, it is recommended to check whether the permanent magnet variable frequency air compressor is normal, whether there is a focus on electric shock, and replace new parts if there is one.
2. Controller:
the controller has a shutdown delay during use, which means that the main controller is broken and needs to be replaced. Since no one presses the shutdown switch while working, it is impossible for the machine to display the shutdown delay. Remember that there are no signs of failure at this time.
3. Fuse:
when the permanent magnet variable frequency air compressor starts normally, during the star-delta conversion process or when the load operation is shut down, first check whether the fuse is a fuse and whether it is a fuse. Check again whether the motor and head are stuck. At this time, the overcurrent should be stopped, and it is recommended to check the motor and magnetic head.
4. Intake valve failure:
the valve cannot be closed during unloading while still inhaling, causing the high pressure to close.
5. Oil core blockage:
the quality of lubricating oil is poor, and long-term use of lubricating oil may cause oil blockage. The internal pressure of the machine is high, and the oil is lower than the high temperature of the machine. Under normal circumstances, the internal and external pressure difference between the oil core and the core shall not exceed 1kg.
6. Fault of emergency stop switch:
if the emergency stop switch fails, the machine will also stop working, and the failure of the pressure or temperature sensor will cause the machine to stop working.

The use of any machine is to the correct maintenance, in order to make the machine life long. Permanent magnet variable frequency screw air compressor is no exception, the correct maintenance of permanent magnet variable frequency screw air compressor service life and maintenance costs have a great impact, this point from the actual interests of the enterprise is very necessary.
View detailsOil-free air compressors have now been applied to pharmaceutical factories, mainly because the performance and characteristics of oil-free air compressors meet the requirements of pharmaceutical factories, oil-free air compressors have great use value in pharmaceutical factories. In the pharmaceutical factory, the use of compressors
Shenzhen air compressor factory direct sales, Shenzhen what factory in the air compressor machine at low temperature and at room temperature, the service life of the oil filter is not the same, low temperature models will greatly slow down the carbonization of filter paper, prolong the invalid use of filter paper time; In addition, poor filter paper is invalid.
It is obvious to all that the oil-free water lubrication air compressor is excellent. As a category of air compressor, the sales volume is increasing year by year. Users who do not understand its advantages can read this article. 1. The compressed gas of the non-oil-water lubricated air compressor is 100% oil-free, the whole structure of the air compressor is more reasonable, and the cost of maintenance consumables is less;
Is there really a "oil-free air compressor manufacturer" with 100% oil-free compressed gas? For companies that have not used "oil-free air compressors", it is normal that they do not understand "oil-free air compressors".
Air compressor is the abbreviation of "air compressor. As early as 1640 AD, the first (mechanical) vacuum pump made in Germany, now, with the improvement of technology, air compressors have been busy in all walks of life, such as food, tobacco and other metallurgy, petrochemical, chemical fiber, pharmaceutical and so on.
The medical air compressor must be controlled within 60 decibels, and the sound of the general household air-conditioning compressor (about 55 decibels), medical staff will not feel uncomfortable working in such an environment. In view of the relatively quiet environment required by the hospital, air compressors with noise higher than 60 decibels cannot be used in hospitals.
View detailsThe specific application of screw air compressor in food and pharmaceutical fields, the application of air compressor in various industries is very extensive, but the requirements of different industries for screw air compressor are also different. The application and light of screw air compressor in food and pharmaceutical fields are introduced in detail below.
There are so many domestic air compressor manufacturers, and the number is large. Before purchasing, it is best to look at the factory scale, production capacity, and various certifications and user cases of the product, and evaluate whether the air compressor manufacturer can meet its own needs.
View detailsGranklin Group is a domestic manufacturer of self-produced water-lubricated air compressors. We can achieve a pressure of 0.15-4Mpa. Water-lubricated air compressors can provide pure oil-free compressed air for enterprises. Energy saving inverter control of the air compressor and the traditional control of the air compressor, the energy saving version is the most important and the most important, according to the demand for compressed air to adjust the supply of air compressor running state.
