For hydraulic valves in oily medium, oil selection is very important. Russian client accepted AAK's suggestion on the selection of hydraulic oil, and successfully got the trust back from their customers.
 
The quality of oil will also affect the service life of the hydraulic valves. At present, many users in the market use HL32 hydraulic oil. It has the lubrication of circulation system and is also cheap. At the same time, it can prolong the oil change cycle. Compared with machine oil, it can save 1 / 3-1 / 2 of lubricating oil, so it has become the first choice of many users.
 
When the lubrication effect of hydraulic oil is poor, impurities are easily entered, which leads to severe wear of valve spool. At the same time, the air release value, anti bubble property and poor water separation performance easily lead to rust and scrap, and shorten the service life of the hydraulic valves. Many users often ignore the oil quality, and the manufacturers of hydraulic valves do not give the guidance on the use of hydraulic oil. This will affect the quality and also the service life of the hydraulic valves.
 
Some time ago, in a chat, a Russian client asked why the same batch of AAK hydraulic valves had different service lives. The client promised the users that the quality guarantee period of AAK hydraulic valve is 1-2 years, but problems came out in only about 8 months, some users complained about the quality.
 
I am very surprised. After further depth communication, I learned that the "cause" is that the medium has affected the service life of the hydraulic valves. At present, the oily medium used by the users who complained is HL32 hydraulic oil. I analyzed the instability of No. 32 hydraulic oil to the client. Due to its poor air release value, anti bubble property and water separation performance, it is easy to cause rust and scrap of hydraulic valves. This oil quality is only suitable for lubrication of bearing boxes and low-pressure circulation systems of various machine tools without special requirements for oil quality, and is not suitable for hydraulic valve system.
 
After listening to my analysis, the Russian client said that no supplier had ever mentioned about the requirements of hydraulic oil, and asked me how to make the guidance for the users. We advised that these problems can be solved as long as HM46 hydraulic oil can be used, it can quickly separate the water mixed in the oil, has excellent oxidation stability and hydrolysis stability, and can resist the influence of air, moisture, high temperature, high pressure and other factors.
 
After half a year, the Russian client did not mention this problem. A phone call came in one day, and I knew that after listening to my analysis that day, he immediately suggested that the user try to change the hydraulic oil to improve the service life of the hydraulic valve. This call mentioned that the effect was obvious and he got the trust back from the users successfully. He appreciated that we found an effective solution for the problem.
