What kind of computers are used in the control systems of ammonia synthesis?
Thread Content
:'(Gentlemen, I have a question that I’d like to ask everyone!) The Dell computers used in our ammonia synthesis control system break down very easily; the problem is mainly with the motherboards, which suffer from severe corrosion – when those motherboards are taken out, they are completely black. I wonder if there is any better machine or a good solution? Please give me some advice! Thank you
Be careful to protect it. All I’ve seen are DELL machines, nothing else.
DELL. None of them is,
In harsh environments, industrial PCs can be considered.
Here we have a DELL mobile engineer station (I think that’s what it’s called), a THINKPAD T61 (that’s how I think it’s spelled)
It is also recommended to purchase an industrial computer; you can check it out at http://www.cechina.cn/.
It’s still better to use Advantech industrial computers, but their hard drives are prone to corrosion; it’s advisable to request that both the motherboard and the hard drive be treated to prevent corrosion at the time of purchase. The motherboards of the Advantech industrial computers used in our company have never failed, but the hard drives often do
We all use Dell systems, and they’re still from the 2000 series – it’s unbelievable! ! ! ! !
We used a Dell one, and it broke in less than a year. Seeing other companies use Lenovo’s products, I just bought one to give it a try. I heard that the central control DCS has replaced Dell with Lenovo.
If the conditions are very harsh, industrial computers can be considered; it is advisable to choose those with anti-corrosion features, or one can carry out anti-corrosion treatment oneself (by spraying the motherboard). If conditions permit, purchasing imported industrial computers such as Siemens models will yield much better results. Based on my experience with Advantech’s industrial PCs, they are not much better than DELL’s commercial PCs. DELL workstations offer a higher quality standard than commercial computers, so they merit consideration first. Personally, I feel that vertical chassis are more reliable than desktop-style ones, as the motherboard being mounted vertically makes it less likely for dust to accumulate compared to a horizontal setup. Larger chassis are also more reliable than smaller ones, mainly because they offer better heat dissipation; too small chassis inevitably lead to excessive concentration of components in one area. Additional note: Instrument air can also be used to provide slight positive pressure ventilation for the control cabinets and operation consoles, which helps prevent corrosion. In the case in question, the components inside the control cabinets were not corroded; only the main unit of the operation station was affected. It is likely that the cabinets in question have already been treated (with anti-corrosion components or through positive pressure ventilation). If no such treatment has been applied, corrosion and damage to the components could occur quite quickly. This post was last edited by hxmhn on 2009-4-2 20:23]
We also use DELL computers; it’s not as serious as what the original poster said. The computers here have been in use for three to four years, and they’re still in good condition.
