拖拉机的 Kubota 液压压力调节

在外面工作的感觉是独一无二的。你辛辛苦苦地工作，用双手建造或重塑事物时，往往会有一种永恒的目标感和自豪感。拖拉机是帮助我们进行户外活动的绝佳工具，无论是工作相关的还是业余爱好和其他充满激情的项目。

与您的汽车或卡车一样，拖拉机也需要基本维护，了解如何检查和正确维护拖拉机中适当的液压油液位非常重要。

什么是流体静力学？

流体静力学是处理静止流体的物理学，特别是流体中的压力或流体施加的压力，通常在活塞等封闭系统中。

流体动力学将处理流动的流体。约翰迪尔拖拉机的液压系统根据流体静力学原理运行。不可压缩流体（如水或油）产生的巨大压力具有在封闭系统中做功的巨大能力。您的 John Deere 拖拉机和您的汽车中的制动器都采用了这一原理。

压力系统，如液压系统，非常有用，但如果处理或维修不当则可能非常危险。拖拉机移动铲斗或操作反铲的液压缸需要适当维护。否则，它们会构成真正的安全隐患，并可能导致昂贵的维修费用。

使用适当的液压设备是对拖拉机进行适当检查的关键步骤。在您信任网上的随机品牌之前，您可能应该看看久保田和约翰迪尔等成熟的专业品牌——这些品牌受到使用这些拖拉机谋生的专业人士的信赖。

为什么液压对拖拉机很重要？

拥有液压系统可以让您的拖拉机操作许多不同的工具，并让它们由同一台发动机提供动力。柴油发动机将为泵提供动力以产生压力来移动气缸。没有压力，你就没有工作能力。

反铲或铲斗和铲刀等标准拖拉机附件均采用液压系统操作，而您看到膨胀或收缩的气缸是包含不同量液压油的活塞。如果包含加压液压流体的管线变得太低，那么您就有发生灾难性故障的风险。

同样，太大的压力也会使线条破裂。拖拉机是一种复杂的机器，就像您的汽车或卡车一样。然而，与您的汽车或卡车不同，许多系统使用不同的充满液压流体的压力系统来移动巨大的负载。

现代拖拉机设计还可以采用静液压传动，使用加压液压油代替传统的皮带和齿轮传动来传输发动机的动力。提供许多扭矩优势的静液压传动装置，如为反铲提供动力或提升铲斗的活塞，需要液压油绝对清洁。大约每 500 个工作小时需要更换或清洁过滤器，如果不是更频繁的话

什么是液压压力表？

使拖拉机保持运转的最佳工具是液压压力表。它监测管路中的压力。

压力太小，气缸将无法移动，您可能会损坏泵。太大的压力同样不利于表现。您的拖拉机旨在使用特殊类型的液压油在特定的狭窄压力范围内发挥最佳性能。

如果压力表不工作，切勿操作拖拉机！高压下的系统本质上是一颗等待爆炸的炸弹。液压系统中有很多能量，如果充电过高，某处的结构缺陷可能会导致爆炸性减压或爆炸！

但是，您的液压表并不是一个非常智能的工具，尽管它记录了适当的压力，但气缸可能不会移动。稍后会详细介绍。

有许多液压油可用于不同的用例，但对于拖拉机，您需要特定的化学成分和粘度，或液压油的稠度。粘度是流动阻力的术语。 Compared to water, oil flows more slowly; thus, it is more viscous. Molasses is very viscous. It is essential only to use the proper hydraulic fluid in your tractor, or you risk premature wear and tear that will shorten the useful life of your tractor.

Kubota hydraulic pressure adjustment options

Hydraulic pressure test kits are an essential tool for tractor maintenance as well as an emergency repair. Specially designed for hydraulic fault-finding as well as reporting purposes, they check reliability, safety, and leak tightness of pressure systems like those on your tractor. These hydraulic pressure testers perform operational checks, including the ability to accurately assess:

• Oil flow
• Hydraulic fluid pressure
• Temperature
• Diagnose poorly operating parts

To operate one, disconnect the pressure line in question and connect it to the tester. It will diagnose issues that otherwise can go unnoticed.

Although expensive, the return on investment is significant. More so, if you use it as part of a warranty claim, helping you to replace faulty components, and avoid machine downtime and out-of-pocket expenses. Unlike your basic pressure gauge mentioned earlier, these hydraulic pressure testing kits give you an expert level diagnosis of common and uncommon faults with your tractor.

There are many hydraulic pressure adjustment options. Which one is best for you depends heavily on the use-case you have with your tractor. If you are a farmer or work in construction, then the ability to diagnose issues quickly is worth paying more money for a more professional-oriented kit with more components and the ability to diagnose problems across a wide pressure spectrum. For the home-gamer type, this type of kit may be overkill, and a cheaper kit with only a couple components is needed.

Regardless of the type of tester you have, repairing and replacing parts is not the same as diagnosing the issue. Unless you are a certified professional, it is strongly recommended that you do not perform certain repairs yourself. With pressure systems like hydraulics, a part that is improperly installed or is accidentally damaged when replacing another can create a dangerous feedback effect that could result in an accident.

Final thoughts

Your tractor is likely a cherished possession. Whether you use it to mow your field, build homes, or farm the land, your tractor is a niche tool that most people will have no active need for. But, as any tractor owner will attest to, if the need for a tractor arises, they can in minutes to hours perform tasks that would require dozens to hundreds of man-hours of labor.

Therefore, it is imperative to make sure that your tractor is adequately maintained. The diesel engine is little different than other internal combustion engine machines you have used, but the hydraulics are a different beast entirely.

Pressurized systems like hydraulic cylinders are tremendously powerful, but if not properly maintained, they are a significant safety hazard. Knowing how to check the various hydraulic fluid levels in your tractor, be it John Deere, Kubota, or something else, is extremely important when it comes to ensuring your tractor is working properly and avoiding costly machine downtime for extensive repairs.

You need to be well qualified to repair your tractor, but every tractor owner and operator should know how to check the basic hydraulic fluid levels.
