Have you ever bought and used an oxygen compressor? In fact, even if it is simple, using an oxygen compressor is not an easy task. However, the maintenance of the oxygen compressor is equally important.

How to use an oxygen compressor?
Using an oxygen compressor is not as complicated as you think, it is actually very simple. After the compressor is installed, it can run normally after normal testing. If you want to adjust the parameters, please follow the steps below:
1. Pressure switch set point adjustment
The machine usually has 2 pressure switches. To find the equipment you need to adjust, you not only need to know how to use the oxygen compressor, but also need to know the maintenance of the oxygen compressor, because it is related to normal use. Control principle: loading pressure (starting pressure) + differential pressure = stopping pressure.
l When adjusting, take the pressure gauge as the standard and loosen the fastening nut;
l Reduce the loading pressure: turn the pressure adjustment screw clockwise (pointer up, pressure decreases) for half a circle, and observe whether the loading pressure meets the requirements (because the pressure difference is not adjusted, the stop pressure will change accordingly), otherwise, adjust appropriately.
l Increase the pressure difference: turn the pressure difference adjustment screw counterclockwise (the pointer moves down, the pressure difference increases) for half a circle, if there is no adjustment, observe whether the pressure difference is the stop pressure.
l After resetting each pressure value, lock the nut and correct the parameter once. As mentioned above, increase the loading pressure or decrease the pressure difference and reverse the adjustment. The adjustment method of the inlet pressure switch is basically the same, but the wiring method is different. At this time, the stop pressure = start pressure-differential pressure. It is strictly forbidden to operate the machine above the rated exhaust pressure.
2. Temperature controller adjustment
Each stage of the compressor is equipped with a temperature controller, which is installed on the control cabinet panel and set in the factory.
Set up, if you need to reset, please refer to the manual of the intelligent temperature controller.
3. Thermal relay adjustment
Thermal relay is used as motor overload protection. Sometimes, the motor will stop rotating. If it is determined that the set value is faulty, it should be properly adjusted through professional electrical work and the running current should be measured. When the compressor is working normally, there is less work that needs to be maintained, but it must be handled by a special person. Each shift should be patrolled twice to observe whether the compressor has abnormal heat, abnormal vibration, abnormal sound, etc. If necessary, stop the operation immediately. After confirming the troubleshooting, you can continue to run. At the end of each gear shift, the power should be turned off and the intake valve should be closed. In order to ensure the long-term reliable operation of the machine, the machine must be inspected regularly.
Daily maintenance and precautions of oxygen compressor
1. The compressor must be carefully inspected and inspected during operation, monitor the compressor's operating conditions, closely monitor the suction, discharge pressure and temperature, discharge volume, cooling water temperature and other control indicators, pay attention to abnormal sounds, and Record from time to time.
2. During the operation, strictly prevent the process gas from being pressed into the low-pressure cylinder and other gas pipelines by the high-pressure cylinder to prevent the entry of oil, water and liquid.
3. It is forbidden to run the compressor under over-temperature, over-pressure and over-speed. If there is any abnormality, please troubleshoot carefully and report it in time.
4. Air leakage When the vehicle stops in an emergency, the substation should cut off the power supply.
5. When servicing the equipment, please carefully check the maintenance license and related safety inspection regulations to ensure the safety of the inspection.
6. When using an oxygen compressor, do not use oily sand to wipe the equipment, pipes, valves and accessories. Do not be contaminated by oil. After inspection, degreasing treatment should be carried out, and flammable gas leakage monitoring equipment should be provided.
7. Check the machine room and stack flammable materials at will.
in conclusion
You don't have to worry about the quality of the compressor, because our oxygen compressors, nitrogen compressors, carbon dioxide compressors, etc. have passed the EU CE certification and are recognized as the safety of compressors. If you still don't know how to use it, you can consult us. But we must pay attention to maintenance work.
