The low cost way to keep your cooling system trouble-free.
More than 40% of all engine troubles begin with cooling system problems. Once these problems start, they spread through your engine, transmission, and hydraulic system. As a result, power is drained, productivity is decreased, and major breakdowns can occur. Our S-O-S 冷却剂分析 detects potential problems before damage occurs. It is a two-level analysis that verifies the proper make-up of your coolant and diagnoses the condition of your cooling system. This allows you to correct coolant deficiencies inexpensively before costly problems arise.
发动机S-O-S冷却剂分析
Engines are obviously the most likely to suffer problems from poor cooling system maintenance. More than half of all engine problems are caused or accelerated by poor cooling system maintenance. 在引擎, overheating can contribute to reduced lubricity and rapid deterioration of the oil. This may manifest itself as a component failure (ring and liner wear, bearings, valves, etc.) which masks the fact that cooling system maintenance was a contributing factor.
S-O-S 冷却剂分析 for Transmission and Hydraulic Systems
Transmission and hydraulic component life are also dependent upon a properly functioning cooling system. 事实上, high oil temperatures can cause early oil deterioration and damage to components in any oil washed system.
在照顾猫讲座期间, we often advise customers that their hydraulic systems will perform well if they keep them “Clean, 关闭, 酷.“如果这三个因素都实现了, the hydraulic oil will last until the recommended change period and the system components will last their design life. 然而, even if the oil is kept clean and closed, it will deteriorate if it is overheated. A poorly maintained cooling system can allow hydraulic oil to overheat, 导致氧化, 添加剂的消耗, 失去了润滑性. The result is short pump life, valve wear, and seal failure. S-O-S oil analysis can spot the oil deterioration, but this alone may not identify the cause. S-O-S coolant analysis can determine if the cause of the problem is poor cooling system maintenance.
Similarly, transmission oil can deteriorate as a result of overheating. In transmissions, the process can be accelerated by clutch slippage.
恶化的冷却剂
冷却剂/防冻剂本身会随着时间的推移而变质. 过热会加速这种恶化. The periodic addition of Supplemental Coolant Additive (SCA) to the standard coolant/antifreeze is intended to replenish the additives (primarily nitrites) which protect the engine parts from corrosion and erosion. 如果SCA浓度过低, 腐蚀/侵蚀将发生, eventually resulting in a pinhole in a cylinder liner, 导致戏剧性的失败.
然而, 如果SCA浓度太大, the silicates and phosphates can precipitate out forming abrasives which cause water pump seal failure. This seal failure allows coolant to enter the engine’s lubrication system. Therefore, it is imperative to achieve a proper balance within the coolant chemistry. 猫erpillar Extended Life Coolant eliminates this particular problem.
On-site test strips and quick tests are not fully adequate to assure a safely protected cooling system. Thus, there is a need for a more comprehensive means of analyzing coolant.
环境问题
Another factor that has focused more attention on coolant is the worldwide emphasis on the environment. Ethylene glycol is extremely hazardous if ingested by humans or animals. 因为这个原因, some machine owners operate their coolant longer to reduce the need for disposal. Disposal of used antifreeze can be difficult and expensive.
因为所有这些原因, 猫erpillar recognized the need to introduce coolant analysis into the S-O-S program.
两个层次的分析
There are two levels to the S-O-S coolant analysis program. The simpler of the two, Level 1, is recommended after every 500 hours of machine operation. Level 2 is recommended every 1,000 hours, or a minimum of once a year or as dictated by Level 1.
一级是基本的冷却液维护检查. It determines if the coolant has the right balance for proper heat and corrosion/erosion control. 这些试验是为了检查乙二醇的含量(冻结) & 煮保护), SCA浓度(腐蚀/侵蚀防护), pH值(酸), 和电导率.
二级是全面的冷却系统分析. It includes all of the Level 1 tests and goes one step further. It completely analyzes the coolant and its effect upon the cooling system. 这些测试可以确定金属的腐蚀情况, 其他污染物, and built-up impurities which point to corrosion and scaling problems before they lead to more costly repairs. 更多详情请联系您最近的猫经销商.
