Noiseless Oil-Free Air Compressor Faq And Maintenance
In this article, we will mainly talk about the common problems and maintenance of noiseless oil-free air compressor. In addition to the noiseless oil-free air compressor on the market, the most common oil-free silent air compressors are also called air pumps! Oilless air compressor is large machines, and their failure problems are more complicated! Today, we will talk about the common failures of small oil-free silent air pumps!
First,the current of the air compressor is too large. The common causes of this type of failure are as follows:
1. Main engine failure.
2. Exhaust pressure is too high.
3. Low voltage: Generally, the power of oil-free air compressors is rated power, so low voltage will inevitably cause high current.
Second,common causes of insufficient air supply failure of noiseless oil-free air compressor:
1. Leakage.
If there is a sound of gas leakage in the external pipeline of the air compressor, it must be handled in time. In addition, it is necessary to check whether the joints such as the air supply pipeline, one-way valve, safety valve, and pressure switch are leaking.
2. Wear of the head leather cup: Generally, the leather cup has a life of about 3 years and must be replaced after expiration.
3. Machine overload.
4. Exceeding the rated flow.
Third,oilless air compressor works intermittently and the air supply is insufficient:
The causes of this failure are:
1. Leakage of the starting capacitor.
When leaking, the compression head can also start, but the speed is slow and the current is large. Because the current is large, the head heats up quickly, and the head can be quickly protected and stopped. The solution to this problem is to replace it with a new one, and it is necessary to pay attention to the same UF number.
2. It is insufficient voltage.
There is a buzzing sound when starting. If you observe that the running current is too large at this time. Starting will cause the head temperature to rise. The terminal protection stops. Until the temperature drops, start again. For areas where voltage fluctuates frequently, it is recommended to install an automatic voltage stabilizer.
Fourth, there is a lot of noise during operation.The causes of this fault are:
1. The oilless air compressor fixing device or accessories are loose.
2. The running current is abnormal.
3. The motor bearing is seriously worn.
4. The leather cup is damaged.
Every time the oilless air compressor works, the air pressure of the air tank can only be started at zero air pressure, otherwise it cannot be started. When the power is turned on, you can see that the head rotates slowly, the buzzing sound, and the current is large. The cause of this fault may be the blockage of the one-way valve. The one-way valve of the oilless air compressor is installed between the exhaust pipe of the air compressor and the air tank. Its main function is to make the gas generated by the head only enter the air tank, and the gas in the air tank cannot come out. The spring and film are the parts. If dirt sticks to the film, it will cause reverse leakage, and the secondary start of the machine head will cause the high pressure to be suppressed and unable to start. The solution is to open the one-way valve on the valve body by hand, and then wash the valve cover and install it again.
The above are the problems and maintenance methods that may occur when using the silent oil-free air compressor. I hope it can be helpful to everyone!
