2.Salt Spray Testing on Rod

Chrome Plated Rods

Chrome Plated Rods are produced from medium carbon cold-finished or hot rolled steel bars usually in Steel 1045/1050 or 10v45 grades. The bars need to be polished, and chrome plated to a minimum thickness of 0.0005″, and 0.001″ per side. Chrome Plated Rods are specifically designed to be used for most piston rod applications in hydraulic cylinders.

 

Nikrom Rod

As some of customers’ machines working environment is highly corrosive conditions, which required very high corrosion resistance. HangZhou LD provides an option of Nikrom rod.
Due to the presence of natural micro cracks in the chromium layer, erosion may penetrate the coating. In corrosive environments or strictly safe applications, exposure to the risk of mechanical damage, oil film alone is not enough to protect in the field.

 

This is especially true if the piston rod remains elongated for a long time as the oil film dries out. By combining the chromium plating with the lower nickel layer. Nikrom can greatly improve the corrosion resistance regardless of the overall oil film protection state of the piston rod.

Nitrided-Treating Rods

Compared with chrome plated rods, Nitrided rods’ black colored surface finish is very hard, and the hardness can be above 55 HRC. The process of liquid nitriding begins with the cleaning and super-polishing of the material to a surface roughness of 6 to 10 Ra.

 

The improved corrosion resistance can reach the requirements of 500-1000 Hours by Salt Spray Testing (ASTM B117), the nitrided rods are normally sufficient to protect the shaft during its entire life. Nitrided rods are cost effective alternative way for longer time salt spray testing requirements.

4.Forging Fabrication For Hydraulic Cylinder Components

 

What is the process of Forging ?

Forging is the process of working or forming metal to the desired shape by impact or pressure from hammers, presses or forging machines. The metal object produced through this process is termed a forging.
 

Forging Advantages ?

Forgings are superior over castings and fabrications as the structural integrity can withstand the higher forces that exist in a rigorous or high duty cycle application.
 

Why Choose Forging ?

Forgings are best used in high duty cycle or more rigorous applications where a more durable, high quality hydraulic cylinder is required. This could be within markets such as construction, mining, refuse etc. Forged hydraulic cylinder components provide the best impact resistance due to the improved directional strength of the grain structure created through the forging process. Forgings can also reduce cost in material, machining and even warranty due to it’s superior quality.

How do hydraulic cylinders contribute to the efficiency of agricultural tasks like plowing?

Hydraulic cylinders play a crucial role in improving the efficiency of agricultural tasks, including plowing. These cylinders provide several benefits that enhance the performance and productivity of agricultural machinery. Let’s explore how hydraulic cylinders contribute to the efficiency of plowing and other agricultural tasks:

  1. Powerful Force Generation: Hydraulic cylinders are capable of generating high forces, which is essential for tasks like plowing. The hydraulic system supplies pressurized fluid to the cylinders, converting hydraulic energy into mechanical force. This force is then utilized to drive plow blades through the soil, overcoming resistance and facilitating efficient soil penetration. The power generated by hydraulic cylinders ensures effective plowing, even in tough or compacted soil conditions.
  2. Adjustable Working Depth: Hydraulic cylinders allow for easy and precise adjustment of the plow’s working depth. By controlling the extension or retraction of the hydraulic cylinder, farmers can adjust the depth of the plow blades according to soil conditions, crop requirements, or their specific preferences. This adjustability enhances efficiency by ensuring optimal soil tillage and minimizing unnecessary energy expenditure. Farmers can adapt the plowing depth to different field areas, optimizing the use of resources and promoting uniform crop growth.
  3. Responsive Control: Hydraulic systems offer highly responsive control, enabling farmers to make quick adjustments during plowing operations. Hydraulic cylinders respond rapidly to changes in hydraulic pressure and valve settings, allowing for immediate modifications in the plow’s position, depth, or angle. This responsiveness enhances efficiency by facilitating on-the-go adjustments based on soil variations, obstacles, or changing field conditions. Farmers can maintain precise control over the plow’s performance, ensuring effective soil tillage and minimizing the risk of crop damage.
  4. Implement Versatility: Hydraulic cylinders enable the attachment of various implements to agricultural machinery, expanding their functionality and versatility. In the context of plowing, hydraulic cylinders allow for the attachment and detachment of plow blades or other tillage implements. This versatility enables farmers to adapt their equipment to different soil types, field sizes, or specific plowing requirements. By using hydraulic cylinders, farmers can easily switch between different implements, optimizing their equipment for specific tasks and maximizing efficiency.
  5. Efficient Time Management: Hydraulic cylinders contribute to time efficiency in agricultural tasks like plowing. With hydraulic systems, farmers can operate plows at higher speeds while maintaining control and precision. The responsive nature of hydraulic cylinders allows for efficient turning, maneuvering, and repositioning of plows, minimizing downtime and optimizing field coverage. This time efficiency translates into increased productivity and reduced overall operational costs. Farmers can accomplish plowing tasks more quickly, allowing them to cover larger field areas in less time.

In summary, hydraulic cylinders significantly contribute to the efficiency of agricultural tasks like plowing. Through powerful force generation, adjustable working depth, responsive control, implement versatility, and efficient time management, hydraulic systems equipped with cylinders enhance the performance and productivity of agricultural machinery. These contributions allow farmers to accomplish plowing tasks more effectively, optimize field operations, and achieve improved overall efficiency in their agricultural practices.
