With the screw air compressor operation time to add the failure rate of various accessories will also be added. This paper mainly sums up the common faults of screw air compressor accessories their solutions. Secondary reasons for the effectiveness of lubricating oil:

1. The quality of lubricating oil, the quality of lubricating oil will directly determine its application cycle. Only the lubricating oil consumed by the normal track manufacturer qualified in the quality verification can be changed once in 4000H under the standard environment, while the replacement cycle of the inferior lubricating oil is very short; 

2. Air humidity: the higher the air humidity, the more likely it is to cause the deterioration of the lubricating oil, which will affect its service life; 

3. The impact of acid-base gas, which is mainly related to the operating environment of the air compressor. 

4. Impurities, impurities entering with the air impurities occurring outside the air compressor due to friction, etc. will be purified to the lubricating oil, which will lead to the effect of bad handling method of the belt: check the shape of the drive belt. If there is no serious result such as deformation, it is only necessary to stop the corresponding option of the bolt then make it reach the required condition. If there is damage, it should be repaired in time. Note that the belt tension must be consistent.

Disposal method for solenoid valve without action:

1.Check whether the solenoid valve connector of screw air compressor can be loose dropped. The solenoid valve shall be electrified the connector can be tightened to solve the problem.

2. Check whether the solenoid valve of screw air compressor is stuck. In case of jamming, the steel wire can be poked into the head hole to make it bounce back. remove the solenoid valve, take out the valve core valve core sleeve, clean with CCI4, so that the valve core moves sensitively in the valve sleeve. When disassembling, pay attention to the second device of each component.

3. Check whether the solenoid valve coil of air compressor is burnt. If the solenoid valve coil is burnt out, the wiring of the solenoid valve can be removed measured with a multimeter. If it is open circuit, the solenoid valve coil is burnt out.

4. The solenoid valve leaks. Air leakage will cause the lack of air pressure, which makes it difficult to open close the valve. The reason is that the sealing gasket is damaged the slide valve is worn, which makes several cavities blow by. The above are common faults of screw air compressor accessories solutions.
