Why Construction Machinery Need Automatic Lubrication?

Construction equipment operates outdoors for extended periods, and prolonged friction in various components can lead to wear and damage. Automatic lubrication systems can reduce friction, extending the lifespan of these components. Moreover, automatic lubrication systems can dispense grease at scheduled intervals and in precise quantities, reducing the operational challenges for maintenance personnel.

Maximizing Efficiency and Longevity with Automatic Lubrication Systems

Regular lubrication is only guaranteed with an automatic lubrication system. We recommend it for routine maintenance, while manual lubrication is suitable for points needing attention every 250 hours or more. Centralized lubrication offers numerous benefits: it saves 30-45 minutes of maintenance time daily by lubricating while the machine runs, ensures longevity and reduces costs through precise lubrication, minimizes grease waste, remains unaffected by environmental factors, and enhances the equipment’s resale value. The automatic system provides consistent and efficient lubrication during operation, creating a grease seal around pins and bushings to prevent contamination and ensuring equal oil usage in each cycle, contrasting with manual methods.

The pins and bushings must be lubricated daily.

To extend the lifespan of pins and bushings, we recommend frequent lubrication to ensure sufficient lubricant protection inside the bushings, thus reducing wear. This also effectively prevents dust, sand, and water from entering. These contaminants have a detrimental impact on the pins and bushings, leading to abnormal downtime and increased maintenance costs. If manual lubrication is used, each machine should be lubricated for no less than 30 minutes daily.

Manual lubrication every day can be challenging due to:

  • Weather conditions.
  • Production demands (centralized lubrication can be performed while the machine is operating).
  • Safety (staff must lubricate various points on the machine).
  • Logistics (manual lubrication equipment may not always be available).
  • Excessive lubrication points.
  • Not all staff can ensure proper lubrication.

Failure to lubricate each point or meet each lubrication requirement can damage the machine, making the “timeliness” of maintenance very important.

Common problems when manually lubricating a set of bearings include:

  • Uneven distribution of grease within the bushing.
  • Incomplete lubrication (insufficient oiling).

Costs incurred due to improper manual lubrication include:

  • Maintenance and replacement part costs.
  • Downtime due to unexpected failures.
  • Increased wear of bushings, pins, and other components.
  • Reduced equipment lifespan.
  • Grease wastage and environmental pollution caused by over-lubrication.

Efficient Lubrication Systems for Construction Machinery
What component in the automatic lubrication system?

Construction machinery lubrication systems are crucial for distributing lubricants, such as oils and greases, to parts of the machinery prone to friction. The key components of these systems include:

  1. Automatic Pump: The pump is the core of the system. In construction machinery, pumps with capacities of 4kg and 8kg are commonly used. Sometimes, we also equip these with a 5-meter extension cord for added flexibility.
  2. Controller: We offer two types of controllers: one with a metal casing and another with a plastic casing. The plastic-cased controllers are generally placed in the cabin, allowing the operator to set lubrication times and monitor the system.
  3. Metering Devices: On construction machinery, we typically use integrated progressive working plates. The advantage of these plates is the ability to adjust the oil output at each point on-site. They contain no rubber parts, making them suitable for extreme weather conditions.
  4. Hoses: For the hose system, we usually select high-pressure resin tubes with an external diameter of 8.6mm and an internal diameter of 4mm. These tubes are made from glass fiber reinforced materials and can withstand an explosion pressure of up to 80Mpa. For parts subject to more friction, we can add protective spring sleeves to safeguard the tubes.
  5. Fittings: The fittings are generally made of steel, and the standard sizes for construction machinery are mostly PT standard, 1/8 or 1/4. The specifications include right-angle or straight-through fittings.

Each of these components is designed to work in unison, ensuring efficient and reliable lubrication in various operating conditions, thereby prolonging the lifespan and performance of the machinery.

In heavy machinery, lubricants are used to reduce friction, prevent wear, dissipate heat, and protect the moving parts from corrosion and damage. The type of lubricant used in heavy machinery depends on various factors such as the specific application, operating conditions, equipment design, and manufacturer recommendations.

Generally, heavy machinery relies on lubricants that can withstand high loads, extreme temperatures, and harsh environments. Here are some common types of lubricants used in heavy machinery:

1. Mineral Oil-based Lubricants: These are traditional lubricants derived from petroleum and are commonly used in heavy machinery. They offer good lubrication properties, suitable viscosity, and can provide protection in moderate operating conditions. However, they may require more frequent oil changes and maintenance.

2. Synthetic Lubricants: Synthetic lubricants are chemically engineered to provide enhanced performance and durability compared to mineral oil-based lubricants. They offer better resistance to high temperatures, oxidation, and have improved viscosity characteristics. Synthetic lubricants are often used in heavy machinery operating under extreme conditions or requiring extended oil change intervals.

3. Greases: Greases are semi-solid lubricants consisting of oil and a thickening agent (usually a soap). Greases are commonly used in heavy machinery applications where a solid or semi-solid lubricant is preferred over liquid oils. Greases provide excellent adhesion, water resistance, and can stay in place even under high loads and vibrations. They are often used in bearings, gears, and hinges of heavy machinery.

4. High-Performance Additives: In addition to base lubricants, heavy machinery lubricants may include additives to enhance their performance. These additives can include anti-wear agents, extreme pressure additives, antioxidants, corrosion inhibitors, and viscosity modifiers. These additives further improve the lubricant’s ability to protect and extend the life of the machinery.

It is important to note that the selection of the lubricant for heavy machinery should comply with the equipment manufacturer’s recommendations and guidelines. They often specify the type, viscosity, and other important factors to ensure optimal performance, reliability, and longevity of the machinery. Regular maintenance and monitoring of the lubricant condition are also crucial to avoid potential issues and costly equipment failures.

The choice of the best lubricant for heavy equipment depends on several factors, including the specific application, operating conditions, equipment design, and manufacturer recommendations. While there is no one-size-fits-all answer, here are some commonly recommended lubricants for different components of heavy equipment:

1. Engine Lubricant: For heavy equipment engines, it is generally recommended to use high-quality diesel engine oils that meet industry standards like API (American Petroleum Institute) classifications. These engine oils should have the appropriate viscosity grade for the operating temperature range and provide excellent protection against wear, oxidation, and deposits.

2. Gear Lubricant: Gear lubricants are used in heavy equipment transmissions, differentials, and final drives. Heavy-duty gear oils with proper viscosity grades, such as SAE (Society of Automotive Engineers) 75W-90 or 85W-140, are typically recommended. These gear oils should have robust EP (Extreme Pressure) additives to withstand high loads and protect gear teeth from wear and pitting.

3. Hydraulic Lubricant: Hydraulic systems in heavy equipment require hydraulic fluids that can provide lubrication, corrosion protection, and efficient power transmission. High-quality hydraulic fluids with the right viscosity, such as ISO VG (Viscosity Grade) 32, 46, or 68, are commonly used. These fluids should have good anti-wear properties and be compatible with seal materials used in the hydraulic system.

4. Greases: Grease is commonly used for heavy equipment components such as bearings, pins, bushings, and linkages. The choice of grease depends on factors like load, temperature, speed, and water resistance requirements. Lithium complex greases are often recommended for heavy equipment due to their excellent performance in various conditions.

It is crucial to follow the equipment manufacturer’s recommendations for lubricants and adhere to proper maintenance practices. Regular oil analysis, monitoring lubricant condition, and adhering to recommended oil change intervals are essential to ensure optimal performance and longevity of heavy equipment.

Additionally, consulting with lubricant suppliers, industry experts, and equipment manufacturers can help in identifying the best lubricant for specific heavy equipment applications.
