How To Scientifically Select Custom Hydraulic Cylinders?

Clarify the basic parameter requirements: The starting point of customized design

Before customizing a hydraulic cylinder, it is necessary to precisely define the basic parameters:

1. Working pressure: Determine the cylinder wall thickness and sealing grade based on the maximum pressure requirement of the system to avoid the risk of overpressure.

2. Stroke length: Calculate the effective stroke based on the equipment's movement trajectory and reserve a safety margin of 10% to 15%.

3. Installation form: Earring type, flange type or foot type must be precisely matched with the structure of the equipment.

4. Load type: Distinguish between thrust and tension loads, dynamic and static working conditions, and optimize the diameter of the piston rod and the guiding structure specifically.

Material and process selection: The core barrier to quality assurance

1. Cylinder block material: Conventional pressure: 45# steel quenched and tempered treatment; High pressure/heavy load: 27SiMn seamless steel pipe, yield strength ≥800MPa;

2. Piston rod treatment: Hard chromium plating + polishing, roughness Ra≤0.2μm;
