Drive chain lubricant should have the following characteristics: 1. viscosity low enough to penetrate the lubricating oil lubricated surface; 2, in the normal bearing pressure can be maintained sufficiently high viscosity lubricant film or adding an appropriate additive; 3, clean and free of corrosive materials; 4, under normal operating conditions, the ability to maintain lubrication quality. Typically, it refined from petroleum, detergent-free high-quality lubricants, to meet these requirements. Generally we do not need detergents, but preferably contain anti-foaming, rust and increased film strength additives. Avoid the use of low-quality or impure oils, low quality lubricants can provide effective lubrication, and wherein the acidic substance or abrasive particles damaging chain enables standard lifting chain, not repairable. Heavy oil or grease too thick can not penetrate the inner chain, it should not be used. Lifting equipment is used in most of the sling lifting chain, but a chain of drawbacks is susceptible to rust and rusty chain-related equipment after very bad for our normal operations are unfavorable lifting chain, so we need to learn rust. In fact, the chain of corrosion protection is very simple, as long as we avoid wet working environment can, if forced to operate under special circumstances, that we would just wipe the chain after use a clean and dry, then apply a layer lifting chain lubricant production, the thickness of the lubricant should be appropriate, no protection is too small, too much can also play a counterproductive. Lifting chain rust is a very deep knowledge, that it is relatively simple lifting chain parameters, in fact, inside there are a lot of details need to pay attention, if not pay attention to detail, our work is wasted, pay attention: the chain during We must pay attention to the gap at the special treatment, which we most easily overlooked, and is the most dangerous place. Lifting chain parameters, Chen power lifting chain (certification), Dalian lifting chain sling from Hebei chen Manufacturing Limited. Hebei chen sling Manufacturing Co., Ltd. (www.wuzhouds.com) Hebei Baoding, forestry machinery leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Chen led force in a sling with the staff warmly welcome all inquiries negotiations to create chen sling a better future.
