Before the start of air compressors, it is necessary to make some of their checks to rule out hidden faults. Inspection before the start of main power supply voltage of checks and check oil level. 

Check supply voltage: Fluctuations in supply voltage range of about ¡À 5% called for. 

Check oil level: Oil-bit general subject matter in oil 1 / 3 to 2 / 3 is appropriate. Lower than the oil standard 1 / 3, should be promptly added through a filter of the same grade lubricating oil, compressor oil 13 # is preferred in winter, summer application of 19 # compressor oil. Temperature above 10 ¡æ with SAE30, 10 ¡æ SAE10 the following can be used.

Second, the air compressor exhaust and maintenance and fault reduction methods:

Fault: Air compressor displacement reduction:

Failure: Short of petroleum

Reduce the displacement has a direct relationship with the claims details. Once we have in production, lower air compressor displacement on the fault occurred, not only can not press the roller down, and accompanied by some Knocking sound.

Maintenance Methods: We first check the air silencer, and their cleaning, and then observe the oil level and found that the oil level of less than 1 / 3 of oil standard position, immediately filling the same brand of oil, and then start the power switch, a test drive, or a percussion sound. Later, parts of sports bodies crankshaft, connecting rod, piston, cylinder 11 open, it was discovered that the crankshaft had a crack, see fast break, and presumably short of petroleum has been for some time. Because short of petroleum, dry friction occurs moving parts, so that all parts of overloading operation damaged to varying degrees. We damage the moving parts cleaning, grinding, serious change, and then re-install, test machine, Knocking sound disappeared, displacement is also normal. Shows that oil is absolutely indispensable, otherwise no end of trouble. 

Failure: Air filter and muffler bad valve tightness 

Maintenance Methods:Displacement of the lower air-silencer with filter and the tightness of the valve. Noise filter to the air handling cleansing. On the valve plate and the valve on the washing dirt is beneficial to ensure the normal displacement of air compressor. Every 200 hours Conventional under a filter should be cleaned every 500 to 800 hours should be cleaned once a valve.

failure reasons:Poor quality lubricants

Maintenance Methods:Lubricants will cause poor quality piston rings are suck, thus reducing the displacement. Therefore, we should select high-quality lubricating oil. After a long work, may contain impurities in oil, dust, etc., so we need another filter. In general, every 500 ~ 800 hours should be replaced once the oil, and the first use of the oil filter.

Fault: The temperature of exhaust

Maintenance Methods:Also cause the exhaust temperature of the piston ring is suck, cause displacement decreased. As long as the lower temperature, they can solve the problem. Here are two points to note: 

(1) Environmental temperature is not high, usually less than 40 ¡æ. 

(2) If the valve leakage, high temperature exhaust gas will return to the cylinder. At this time we should carefully check valves, grinding disc or replace the valve, remove leakage phenomenon, it was possible to solve the temperature of the problem.
