Discussion on the domestic substitution of specialized oils for imported brand air compressors, refrigeration units, and other specialized equipment
Thread Content
Popular imported brands for air compressors include Atlas, Fusheng, Ingersoll Rand, and Sulzer. Popular imported brands for refrigeration units include GEA, York, Carrier, and LG. Each of these brands uses its own lubricants, which are extremely expensive; moreover, their distribution channels are well-protected, making it difficult to negotiate prices. It is understood that some oils are sold as originally imported products, while others are repackaged after being imported originally and then sold. Some brands add their own additives to the originally imported oils, claiming that they have proprietary oils that must be used with their own machinery; otherwise, the equipment is prone to damage. If alternative oils are used, no maintenance service will be provided, leaving users in uncertainty and preventing them from replacing the oils arbitrarily. Currently, many domestic companies use these brands, but the subsequent maintenance costs are quite high; sometimes the cost of a major repair exceeds half of the original purchase price, and just replacing the lubricant can cost hundreds of thousands. Therefore, there is a large market for oil replacement. Over the past decade or so, domestic oil brands such as Great Wall and Kunlun have invested significant resources in developing alternatives to foreign oils, and they have achieved considerable success in this regard. For example, Great Wall’s fully synthetic lubricant 4502N32 can replace Ingersoll Rand’s GoldTech oil; tests on various performance indicators show that there is little difference between them, with some indicators even being higher than those of the foreign oil. Actual testing after using this alternative lubricant confirms that it meets the requirements of the equipment, thereby **reducing procurement costs**. Currently, large enterprises such as Sinopec and CNPC have already replaced them with domestically produced fuels, which saves half of the costs associated with lubricants alone; however, a large number of companies are still in the process of evaluating whether to make such replacements. So I’d like to create a discussion thread to talk about the issue of replacing specialized oils with alternatives. If any of you out there have relevant experience, please share it; those with actual cases can also go ahead and discuss them. This can serve as a reference for those who are considering doing this or working on such projects, as well as an opportunity for those interested to learn more. At the same time, fellow sailors can also discuss the replacement of commonly used imported oils (such as Shell Resist S4 WE220, etc.)! My writing skills are not good; please forgive me. If there are any mistakes in the text, I ask for your understanding and corrections!
It’s all a trick; in fact, as long as the various indicators are close to the required values, there’s no need to use original engine oil
Makes sense; the more you use these tactics, the more experience you gain!
A despicable trick. But some people like to fall for this trick.
The topic is good; I don’t entirely agree with the viewpoints. There are so many tactics that it’s hard to keep up with them. I’m not sure if my own arguments also contain some kind of manipulative tactic! As a member of the chemical manufacturing industry, which is more important: cost investment in production or the stable operation of the equipment? The imported brand units under discussion are certainly the key core equipment of the installation; the cost of shutting down the plant once is completely incomparable to such investment costs. Of course, some might ask: Does using domestic oil necessarily lead to downtime? Well, I would say that domestic compressors can also be used, and it’s not certain that domestic ones will operate unstably; so why buy expensive imported units? Isn’t it because the main consideration is ensuring the stable, long-term, and optimal operation of the device? Of course, I’m not saying that domestic products cannot replace imported ones. What I mean is that whether substitution is possible depends on factors such as what type of unit it is and its role in the overall production process; the key lies in determining what aspects should be given priority (in fact, I could buy a Mercedes and convert it to run on gas as well). Maybe I was tricked into it.
It’s normal for everyone to have their own priorities when discussing things; it’s understandable that Haiyou thinks more deeply about the issue. What’s important is also to take into account the significance of the equipment. Large chemical companies use many imported pieces of equipment, and they are exposed to them on a large scale. Before replacing such equipment, feasibility analyses, actual oil sample tests and comparisons, as well as expert opinions, must all be considered – only after being confident can the replacement be carried out! It’s not absolute; regarding the two types of equipment mentioned above, I believe that air compressors are as technologically mature as standard components, so replacement should not be a problem. As for refrigerators, factors such as the refrigerant need to be taken into consideration, and it may be necessary to consider different brands depending on the situation. These opinions are provided for discussion only!
For moving equipment that falls under the category of utility systems, backup units are usually available. When choosing imported equipment, energy efficiency is also taken into consideration! Overall, consider comprehensiveness and cost-effectiveness! Lowest total operating cost! It feels like we’re off topic…
In my opinion, for critical equipment, it is recommended to use the original oil during the warranty period; otherwise, if a problem arises, the manufacturer might use this as an excuse to deny warranty coverage, which would be a loss. After the warranty period expires, it is advisable to have a qualified laboratory conduct tests and provide recommendations for alternative oils. For non-critical equipment, other brands with equivalent performance can be considered, but the original oil should first be thoroughly cleaned out
Domestic lubricants, if they come from reputable manufacturers, are not much different from imported ones； Of course, if one focuses solely on price, domestic options can be unbelievably cheap; in such cases, the quality cannot be guaranteed – the specifications won’t meet standards! Most important! What does the warranty period mean? It’s simply a way to make more profit
