Hydraulic cylinders are essential components in hydraulic lifts and lifting platforms, playing a crucial role in the selection of fuel tanks. In this article, we'll explain our approach to selecting hydraulic cylinders and fuel tanks for optimal performance and reliability.
A hydraulic cylinder is a mechanical device that converts hydraulic energy into linear motion. It works by using pressurized fluid to move a piston inside a cylinder, which in turn drives a rod to perform work. These devices are known for their simplicity, durability, and efficiency. By eliminating the need for deceleration mechanisms in hydraulic elevators, they provide smooth and precise movement with no transmission gaps, making them ideal for various industrial applications.
The force generated by a hydraulic cylinder depends on the pressure of the fluid and the area of the piston. The basic structure includes a cylinder body, cylinder head, piston, piston rod, sealing elements, and sometimes a buffer or exhaust system. While buffers and exhausts may vary depending on the application, the core components are always necessary for proper operation.
When selecting a fuel tank, there are several important factors to consider:
1. **Tank Capacity**: For mobile equipment, the tank should hold 2 to 3 times the maximum pump flow rate. For fixed systems, it should be 3 to 4 times the pump flow. This ensures sufficient oil volume for cooling and circulation.
2. **Oil Level Management**: The oil level must not drop below the minimum when all cylinders are extended, and it should not exceed the maximum when the cylinders are retracted. Proper oil levels prevent overheating and ensure efficient system operation.
3. **Tank Design**: Traditional fuel tanks often have partitions that do not effectively separate contaminants. Instead, a vertical partition aligned with the tank's axis is recommended. This design allows for better sedimentation and oil circulation. The baffle should leave space at one end to allow communication between the two sides, while the pump’s inlet and outlet ports should be placed on opposite ends of the baffle. This increases the distance between the oil intake and return, improving system efficiency.
In addition, the fuel tank should also provide adequate heat dissipation to maintain stable operating temperatures.

Heavy Steel Rail on a railway or railroad, also known as the permanent way, is the structure consisting of the rails, fasteners, railroad ties (sleepers, British English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable surface for their wheels to roll upon.
Tee Rail & Light Rail
Tee rail sections are used in a wide variety of applications ranging from transit authority systems to Heavy haul railways.
Light rail sections (85 lb/yd and less) are used for mining, industrial, and crane applications.
