为什么润滑脂是从机器中获得最大的关键

正确的润滑对于重型采矿设备的最佳功能至关重要。雷电竞Viva Energy Gease技术专家Mick Castle谈到如何确保您充分利用您的挖掘机。

When it comes to lubrication for heavy mining equipment, making sure that the grease being used is appropriate for the machinery is of primary importance. It’s also important to check that the grease is within the OEM (original equipment manufacturer) recommendations and guidelines for the lube system and settings, to avoid any impact on warranties.

工厂安装的自动润滑系统（ALS）旨在将适量的润滑剂分配到机器上的所有点，当需要时。但是，为了优化性能，需要定期正确设置和监控系统。

When setting up, every point on the system needs to be physically checked, and the amount of lubricant being dispensed to each point noted. That information should then be measured against the OEM specification and setting to ensure the correct amount of grease is being dispensed relative to the metering device setting. If there’s a discrepancy in output higher or lower than the specification, you may need to change out that injector. Certain injectors, such as Lincoln SLVs and SL-V XLs, can be configured with colour-coded spectrum sleeves; this makes it easy to maintain the correct injector output settings during future injector change outs.

环境因素还会影响系统如何设置和维护。可能是OEM推荐特定量的润滑脂到一个点，但细粉尘或真正的粗糙或湿材料可以将油脂从销和衬套接头中洗涤。在这种情况下，建议调整所应用的润滑脂量，以确保这些点被充分润滑。

维护拯救了金钱

要安排常规检查是否有磨损，并进行预防性维护非常重要。仅在压力下工作的一天，润滑脂不足可能会造成显着的损坏，并将机器放在使用中，导致不必要的下降时间和额外的财务支出。

每个检查点都应该有一个新鲜，均匀的润滑脂，包括摆动轴承的底部密封，臂脚销，动臂到贴销，棍棒和所有其他灌木丛附件。

If there are any dry points, the problem could be a broken grease line, an injector not functioning properly or even that the whole system was not set up correctly in the first place.

The performance of a machine can be greatly reduced if any of the injectors are under-lubing and there’s not enough product getting down to the pins. For instance, you might find you’re only getting 1500–2500 hours out of a set of bucket pins and bushes, when you would normally expect 12,000 hours or the life of your bucket.

另一方面,如果喷油器疲惫不堪nd ‘bypassing’, or dispensing extra grease to every point, you will quite likely find that far more grease is being used than is necessary, and it’s all ending up on the ground. It is possible under these circumstances that a 600-tonne machine that should be using around 1.5 kilograms of grease an hour might in fact be consuming up to four kilos in the same amount of time.

在设备的寿命期间，应该不需要改变臂脚销或摆动轴承等组件，只要：

• The right product is being used.
• 它们正在正确润滑。
• 润滑系统正常运行。

A quick, regular audit has the potential to save considerable wastage and cost, especially if you have multiple excavators working on site.
