Common Problems and Maintenance of Air Compressor

with the development of technology, air compressors are widely used in various industries, but no matter what type of air compressor, there will be some problems in the process of use. The following editor now introduces some common faults and maintenance methods, let's take a look.

Methods:

1. The air compressor is still working, but the air supply is insufficient. The air compressor works at a certain pressure and stops the gas tank.

Use your ears to listen to the air leakage links such as the pipelines outside the air compressor, the compressor air supply pipeline above the air storage tank, the one-way valve, the safety valve, the pressure switch, etc. If the above problems are eliminated, it may be that the scalp bowl is worn or the rated flow rate is exceeded, and the machine is overloaded. As for the damage of the leather bowl, the leather bowl must be replaced. The life of an ordinary leather bowl is about 3 years.

2. The air compressor works intermittently and the air supply is insufficient.

This fault is caused by insufficient voltage. There started to be a buzz. For example, the operating current at this time is too large. The minimum working voltage of the oil-free head is 200 volts, which is difficult to start. Frequent start-ups can cause the head temperature to rise. Final short circuit shutdown. When it turns on again, it should wait for his temperature to drop and turn on. For areas where voltage fluctuations often occur, it is recommended to install an automatic voltage stabilizer.

3. Start capacitor leakage.

When leakage occurs, the compression head can also be started, but the speed is slow and the current is large. Due to the large current, the head of the machine heats up, and the head of the machine will soon be closed. This problem can be changed to a new one, but we should pay attention to the same number of ultrafiltration membranes, too large or too small.

Every time the air compressor works, the air pressure of the air storage tank must be reduced to zero pressure before starting. Otherwise, it will not start. When the power is turned on, you can see that the head rotates very slowly and there is a hum. The current is also very large.

This is because the one-way valve is blocked, its position is connected to the water outlet pipe (or high pressure pipe), and the other end is connected to the gas storage tank, which has three outlets. Its function is to allow the gas discharged from the engine to only enter the air tank, but the gas in the air tank cannot come out. Inside is a spring and a film. If dirt sticks to the film, it will cause reverse leakage. Use the handle to open the bonnet behind the check valve. Please wash it and put it back as it is.

The air compressor can work, but the noise is significantly greater than the original noise.

This phenomenon checks whether the running current of the loose parts on the machine is normal after removal. If it is normal, the machine is usually used for several years. The oil-free air compressor should be placed in an environment away from dusty places. Regularly unplug the power supply and use high-pressure air to blow out the dust on the surface and two fan blades. The noise is too loud because the four bearings are worn by dust, so the cups will also be affected. Replace the tools and accessories that require a special oil-free air compressor.

Air compressor safety matters

the operation of the air compressor system is very safe. Danger is rare, but in rare cases it occurs due to human error. In order to reduce the possibility of human error, the following safety considerations must be kept in mind:

① Read the operating instructions carefully. Understand the working conditions of each part of the compressor by carefully reading the user operation manual provided by the manufacturer.

② Before starting the machine each time, carefully check the external state of the pipeline, joints, control parts and the entire system. It is forbidden to use it when there is a problem.

③ Use a suitable power socket. Using an improperly grounded socket can cause damage to the electrical part. A well-grounded triple socket must be used.

④ Ensure that the surface of the compressor is dry at all times. The compressor should be placed in a place where there is dry, clean flowing air. Avoid dust, dirt and diffuse paint mist splashing on the surface of the compressor.

Most compressors can be automatically turned on and off, and the power supply must be cut off when the equipment is repaired.

⑥ Be careful not to touch the working parts with hands. High-speed rotating parts will hurt the human body. When the compressor is working, take care to remove the hand. Don't wear wide clothes to prevent being caught by rotating parts. Pay attention to unplug the power plug before servicing the compressor.

⑦ Do not remove the protective cover of the transmission belt, ensure that other safety protection devices are connected reliably, and pay attention to keep them in good working condition. Remember that the temperature is extremely high when the compressor is working, do not touch the body.

⑧ Be careful when releasing high-pressure gas. Use an air pressure regulator to reduce the air pressure. High-speed airflow will blow up dust and other foreign matter.

⑨ Avoid knots on the gas pipeline, and be careful not to let the gas pipeline, power cord and external wiring touch sharp objects, spilled chemicals, oil and wet ground. All this leads to danger.

⑩ When removing the pressure of the air storage tank, moving the air transmission pipe or replacing the pneumatic tool, ensure that the reading value of the pressure regulator instrument is zero. Caution: Do not release the high pressure gas too quickly, otherwise it will cause danger.
