Product Description

Product Description

Hydraulic Equipment includes Engineering Hydraulic Cylinder, Hydraulic Cylinder For Metallurgical Equipment, Hydraulic Cylinder For Industry and Thin Hydraulic Cylinder, etc.

1. Cylinder Barrel
The commonly used materials of DGR-MOB Series hydraulic cylinder are seamless steel pipes of 20#, 35#, and 45#, which have been honed or rolled to meet the European roughness requirements of less than 0.4um. Low pressure oil cylinders can use 20# steel pipes, while high pressure oil cylinders can use 45# steel pipes.

2. Piston Rod
There are 2 types of piston rods: CHINAMFG rod and hollow rod. One end of the hollow piston rod should have a vent hole for welding and heat treatment.  The material of the plug rod is 35# and 45# steel, and the material of the hollow piston rod is 35# and 45# seamless steel pipe.
After rough machining, the piston rod is quenched and tempered to a hardness of 229-285HB. If necessary, it is then subjected to high-frequency quenching to achieve a hardness of 45-55HRC.

3. Cylinder Head
Castings for low pressure, HT300 gray iron for medium and low pressure, and 35# and 45# steel for medium and high pressure.
When the cylinder head itself is the guide sleeve of the piston rod, it is best to choose cast iron for the cylinder head. At the same time, brass, bronze. Or other wear-resistant materials should be melted CHINAMFG the guide surface. If a structure with a guide sleeve pressed into the cylinder head is used, the guide sleeve should be wear-resistant cast iron, bronze, or brass.

4. Piston
Commonly used materials are wear-resistant cast iron, gray cast iron (HT300, HT350), steel, and aluminum alloy. The coaxiality tolerance value of the piston and piston rod in the structural diagram should be 0.03mm.

Handling the Challenges of Minimizing Fluid Leaks and Contamination in Hydraulic Cylinders

Hydraulic cylinders face challenges when it comes to minimizing fluid leaks and contamination, as these issues can impact the performance, reliability, and lifespan of the system. However, there are several measures and design considerations that help address these challenges effectively. Let’s explore how hydraulic cylinders handle the challenges of minimizing fluid leaks and contamination:

  1. Sealing Systems: Hydraulic cylinders employ advanced sealing systems to prevent fluid leaks. These systems typically include various types of seals, such as piston seals, rod seals, and wiper seals. The seals are designed to create a tight and reliable barrier between the moving components of the cylinder and the external environment, minimizing the risk of fluid leakage.
  2. Seal Material Selection: The choice of seal materials is crucial in minimizing fluid leaks and contamination. Hydraulic cylinder manufacturers carefully select seal materials that are compatible with the hydraulic fluid used and resistant to wear, abrasion, and chemical degradation. This ensures the longevity and effectiveness of the seals, reducing the likelihood of leaks or premature seal failure.
  3. Proper Installation and Maintenance: Ensuring proper installation and regular maintenance of hydraulic cylinders is essential for minimizing fluid leaks and contamination. During installation, attention should be given to proper alignment, torqueing of bolts, and adherence to recommended procedures. Regular maintenance includes inspecting seals, replacing worn-out components, and addressing any signs of leakage promptly. Proper maintenance practices help identify and rectify issues before they escalate and cause significant problems.
  4. Contamination Control: Hydraulic cylinders incorporate measures to control contamination and maintain fluid cleanliness. This includes the use of filtration systems, such as in-line filters, to remove particles and contaminants from the hydraulic fluid. Additionally, hydraulic reservoirs often have breathers and desiccant filters to prevent moisture and airborne contaminants from entering the system. By controlling contamination, hydraulic cylinders minimize the risk of damage to internal components and maintain optimal system performance.
  5. Environmental Protection: Hydraulic cylinders may be equipped with protective features to safeguard against external contaminants. For example, bellows or protective boots can be installed to shield the rod and seals from debris, dirt, or moisture present in the operating environment. These protective measures help extend the life of the seals and enhance the overall reliability of the hydraulic cylinder.

In summary, hydraulic cylinders employ sealing systems, appropriate seal materials, proper installation and maintenance practices, contamination control measures, and environmental protection features to handle the challenges of minimizing fluid leaks and contamination. By implementing these measures, manufacturers can ensure reliable and long-lasting hydraulic cylinder performance, minimize the risk of fluid leakage, and maintain the cleanliness of the hydraulic system.
