Discussion on Problems Caused by Suspected Oil in Compressor

Discussion on Problems Caused by Suspected Oil in Compressor

Editor's note: In the process of using compressors, in order to achieve the purpose of normal and high-efficiency production, most of the time, we give more choices and maintenance to the host and spare parts, but often ignore the safety Wait for some details of the situation to understand and grasp. It should be noted that "the destruction of a thousand-mile embankment in an ant's nest" seems to be a small problem. If carelessness is not paid, it will not only cause unnecessary waste, but even lead to a major accident one day. Therefore, when the compressor travels far, no matter how big or small the problem is, it needs to be paid attention and thoroughly understood and solved. This is the prerequisite to ensure that the compressor can maintain safe and effective operation.

　　 Then, we started with a product contamination incident caused by a user's suspected compressor oil problem during the application process, and initiated a solicitation of opinions and discussions among industry insiders for the purpose of mutual agreement and mutual benefit. In this issue of the forum, let's listen to the heated discussions among netizens.

　　 Wide participation, sincere communication, many difficulties and problems will be solved, this is the power of the network.

　　Welcome to the okmarts.com forum:

　　 Ask every teacher: I have a customer who uses compressed air to break and stir phosphors, air compressor, air storage tank, refrigeration dryer, and 4-stage filtration are all equipped. Not long ago, I accidentally found that the phosphor after stirring appeared light yellow. I changed the pipeline and the 4-stage filter. After a long time, it turned light yellow again. What's the matter? What is the main reason? Thank you.

　　ID: jldzhong

　　 What will the phosphor turn yellow when it meets? Maybe it's not the compressor problem, you have to figure out if there are other reasons.

　　ID: zhangtianshi

　　 It is certain that the color of the air compressor oil that the customer originally used is yellow. Could it be an oil problem that caused the oil spill pollution?

　　ID: white and black

　　 It is very possible. It is recommended to use an oil-free machine.

　　ID: jysx5127

　　 Is your customer a new system equipment? If so, the air source is very demanding. It is recommended to change the refrigeration dryer to a suction dryer.

　　ID: JQLJPL

　　 Still need to find a way to improve the quality of compressed air, this should solve the problem.

　　ID: zhangtianshi

　　 To add, the machine has been used for more than a year, but it became like this after changing the oil some time ago. Originally, it was filtered by level 2. I suggest changing to level 4. The original oil used was yellow, but I changed to transparent and colorless. All pipes were replaced with stainless steel and cleaned. My method just got better for a long time, and then it became the same again. A friend suggested that the oil should be changed first. I asked, the oil was just changed. Ask everyone, what should I do? ? ? Thank you.

　　ID: Air compressor Wu

　　 The following is a statement quoted from "jysx5127": Is your customer a new system equipment? If it is, the air source is very demanding. It is recommended to change the refrigeration dryer to a suction dryer.

　　 I personally think that this method is feasible, try it.

　　ID: zhangtianshi

　　 But, as far as I know, the drier only has an effect on moisture, and has no effect on oil. Is this possible?

　　ID: adsl65362408

　　You can install a high-efficiency degreaser with a comparable flow rate between the air storage bag and the refrigeration dryer to control oil. Changing the refrigeration dryer to a suction dryer is to strengthen the absorption of moisture, but I don’t know which effect is it?

　　ID: diavyang

　　 The following is a statement quoted from "white and black": It is very possible, it is recommended to use an oil-free machine, after all, it is difficult to clean the system after the system is filled with oil.

　　 I support this point of view, it should be better to deal with this.

　　ID: zhangtianshi

　　 If you want to use an oil-free machine, should you change the post-processing (refrigerator, filter, air tank)?

　　ID: diavyang

　　 is not necessarily, if there is no oil pollution, in fact, it does not need to be replaced.

　　ID: cold fire

　　 This issue seems complicated, but there is no suspense. In the final analysis, it must be oily.

　　ID: hnfysh

　　Personally, it is very likely that there is a problem with your oil product/oil return system/oil separator, please check and rule it out carefully.

　　ID: li321123

　　 I also think there is a problem with the compressor oil.

　　ID: hyldgzj

　　 It is recommended to check carefully to see if the air compressor is running out of oil?

　　ID: huli

First consider whether the oil is replaced with a substitute. If it is, check whether the temperature of the air compressor is normal (the same as the previous temperature. If it is abnormal, change the oil. If it is normal, add another adsorption dryer. In addition, you should also consider whether the quality of the filter element of your several stages of filtration is not a problem.

　　ID: tzw200859498

　　 First, figure out why the phosphor turns yellow? Only in this way can it be targeted!

　　 A suction dryer is used for more water, and the suction dryer is not for oil processing. If there is a lot of oil, the solution is to change the oil-free machine once and for all. After all, there are too many places to check in this system.

There are a lot of reasons for running oil in the forum, I repeat: 1. Check the configuration, whether the filter processing capacity is not enough, 2. The oil itself and whether there is too much oil, 3. The oil and the oil return pipe, 4. The system pressure is low, 5. . If there is a bypass in the post-processing, see if the bypass valve leaks. 6. The quality of the filter itself.

　　ID: Southern Mouse

　　 Is the filtration area of your pipeline filter too small, because the flow rate is high and it can't filter at all.

　　ID: wzhy.m@163.com

The oil return effect is not good, the separation is not good, and the air contains a lot of oil. It is best to explain which manufacturer and which model it is. This will be targeted and facilitate communication and solve problems, because different manufacturers have different models. There are differences.

　　ID: fujunok

　　Excuse me, does your customer's machine use a lot of oil?

　　 If the gas requirements are really high, then you can only use an oil-free machine, which will save a lot of trouble. Don't be superstitious about the filter, its effect is not as good as the sample.

　　ID: leoyong199

I personally think that the main reason is that the oil content of the air compressor is not handled well (the quality problem itself), because the installation of a 4-stage filter will not work. It can be seen that the oil content of the air compressor is too high. It is recommended to replace a good brand air compressor. . 　　ID: wxf

　　The oil return effect is not good, the separation is not good, and the oil content is problematic.

　　ID: shilubin

　　 As mentioned above, if the oil content is the main problem, there are other aspects besides the oil content, such as the position of the oil return pipe in the oil separator, whether the oil return pipe is unobstructed, etc. The main reason is serious oil running.

　　ID: zhangtianshi

　　 Later, there was no adsorption type refrigeration dryer, just replaced with an air compressor. But how to deal with the original two air compressors? Should it be replaced with a better oil, or was it scrapped?

　　ID: zjscq

　　 You have to find the problem first and replace it blindly. If the expected effect is not achieved, the customer will get angry, and you will lose yourself.

　　ID: zhangtianshi

　　 Yes, thank you for your reminder, I am waiting for the customer's reply.

　　ID: WDNGCTA

　　 Although the problem has been solved by replacement repair, I still recommend checking three items when encountering such problems: whether the exhaust temperature is too high, whether the injection temperature is too low, and whether the pressure maintenance valve is long open (damaged). Also, check the tilt of the machine? Look at the oil return pipe, the connection section is transparent, and the oil return can be seen when it is turned on.

　　ID: Yunnan Bolet all

　　You can install a high-efficiency degreaser with a comparable flow rate between the air storage bag and the refrigeration dryer to control oil, and change the refrigeration dryer to a suction dryer to strengthen the absorption of moisture.

　　ID: Foshan Zhongkong

　　 Look for the specific problem, and then sort it out. Our customers have also experienced similar problems. Solution: Check from the gas end to the machine. At that time, the problem was that the secondary oil return pipe was half blocked by a strainer joint before the one-way valve.
