储气罐里面出现空压机油的正确处理方法

The right ways to deal with the oil flow into the air tank

空压机系统中,储气罐主要起到缓冲作用,另外还能起到对压缩空气的初过滤,正常情况下储气罐的排污阀排掉的主要是水及微量的油份,如果发现排出的油比水多,就应该引起注意,判断是否空压机出现了问题。
In the air compressor system,the effect of the air tank (air receiver) is buffer.and also can Primary Filter the compressored air.Under the normal condition,the drain valve of the air tank mainly discharge the water and traces of oil.if the discharged oil more than the water,it should be noticed,determine whether there was a problem with the air compressor.

1.首先,检查油气桶内的油位,油位是否高于上红线,过量添加空压机油,多出的空压机油就会随压缩空气进入到储气罐。
1.Firstly,check the oil level in the oil barrel,check the oil level above the red line or not.excessive add the compressor oil,the extra oil can be follow into the air tank with the compressored air.

解决方法:将空压机停机,排出多余压缩机油,正常的油位应在空压机运行时,在视油镜油标尺上下线之间为合适油位。
Solution:Stop the air compressor,discharge the extra oil,the oil level should be in proper level between the oil mirror up and down line when the air compressor was working well.

2.油位正常的情况下,检查是否使用了不合格的空压机油,不合格的空压机油在温度升高后同样会随压缩空气进入到储气罐。
If the oil level is normal,check the air compressor oil is unqualified or not.the unqualified oil can follow into the air tank after the temperature rise.

解决方法:确定使用的是合格的空压机油,反之则更换油品,不合格的空压机油不光会增加油耗,还会增加内部积碳等其他不良反应,不能因小失大。
Resolution:make sure the oil is qualified,if unqualified,change the oil,the unqualified oil not only increase the fuel consumption ,but also increase the  internal carbon deposition ,and other adverse reactions .do not set fire to your house to keep yourself warm.

3.检查回油管是否堵塞, 当回油管路有异物堵塞时,分离后凝聚在油分底部的机油就无法回到机头,已经凝聚的油滴又被气流吹起,随着分离后的空气一起被带入储气罐。
Check where the oil returned pipe is blocked,when the oil returned pipes are jammed,the oil condensed in the bottom of the oil separator which after separation  will unable to return to the air end.the condensed oil droplets was blown by the air,enter into the air tank together with the separated air.

解决方法:将空压机停机,待油气桶内无压力时拆下回油管,将异物吹出,使之通畅。
Resolution:Stop the air compressor,removal the oil returned pipe when the oil barrel under no pressure condition.blow out the foreign bodies to make it smooth.

4.检查油分芯是否破损,如果是内置油分,须拆下油气桶盖,取出油分,检查完好程度。
Check whether the oil core is damaged,if it is the built-in type,you must discharge the cover of oil barrel and remove oil separator and check it in good condition or not.

解决方法:更换油分,更换时注意不要有杂质掉入油气桶内
Resolution:When you replace the oil separator,make sure do not have impurities fall into the oil barrel.

Two Stage Screw Air Compressor


Two stage air compressors work in a very similar manner with the primary difference being that they compress the air in 2 steps or stages. During the first step or stage, air is drawn in and compressed to an intermediate pressure. After being compressed in the first stage, the air is piped, usually through an intercooler where the air is allowed to cool, to be compressed in the final or second stage. Two stage compressors are normally good for pressures up to 200psi. Two stage pumps are more efficient at higher pressures because the air is cooled between the stages.
DCFM, SCFM and ACFM
            Displaced CFM (DCFM) is a mathematical formula that calculates the bore, stroke and rpm into a CFM figure(Bore x stroke x rpm/2200=DCFM). This figure will always be the highest CFM because this formula does not take into account variables like temperature, atmospheric pressure, humidity, friction and heat dissipation.
Another CFM term often used is Standard CFM (SCFM).  It defined as the measured flow of free air and converted to a standard set of reference conditions (14.5 PSIA, 68 Degrees F, and 0% relative humidity).
Yet another CFM term is Actual CFM (ACFM). AFCM can be determined in a number of different ways. The most common methods include measuring the volume of air that is moved through an orphic plate or measuring pump up times on large compressor tanks and running through a simple calculation. This CFM number takes in effect all the variables and will give the true output of the pump at the current working conditions (i.e. temperature, altitude, humidity, …).
Often times, CFM numbers are also shown at various pressures.  These numbers can be very useful to help determine if a compressor produces enough CFM for the desired application, but can be confusing when comparing differing pressures or volumes or different compressors.
The best way of comparing compressors is through SCFM. Since all the measurements are calculated back to a set of reference standard conditions, it levels the playing field among the multitude of different manufacturers.
Electric Motors and Horsepower
         Compressors are often rated by Horsepower(HP). As simple as this sounds, there are different variations of HP.  Some compressor manufacturers rate their air compressors by peak horsepower, also known as brake horsepower. Peak horsepower is the maximum output that a motor can produce while the motor has the start windings engaged. Peak HP can be as much as 5-7 times the rated or running HP. Under normal operating conditions, the start windings are only engaged for a small fraction of a second. Therefore, using peak horsepower as a comparison tool can be somewhat misleading since under normal operating conditions the motor only develops this horsepower during startup.  If  a motor drive system causes the start winding to remain engaged for a long period of time, the motor will either overheat if it has thermal protection or fail prematurely.
Most electric motor manufacturers rate their motors by the horsepower developed after the motor has come up to its designed operating rpm’s and disengaged the start windings. This is often referred to as running or rated horsepower and is a true indication of the HP a motor can sustain over a long period of time.
Some other factors to consider when looking at motors is Duty Cycle and Service Factor.  Duty cycle is normally rated as either intermittent or continuous and is defined as the time rating under full load.   In other words can the motor run at full load horsepower continuously or only intermittently. The other of the two noteworthy factors is the Service Factor (S.F.) rating of the motor. It is defined as the percentage of rated horsepower at which the motor can safely operate (i.e. 1.15 SF = 115% of rated HP).  Higher service factors allow motors to handle more varied conditions without causing motor overheating or premature motor failure.  Examples that could cause a motor to run within its Service Factor could be caused by low voltage, higher ambient temperatures, higher startup load …etc.
