THE TOP 3 REASONS CYLINDERS FAIL

摘要

Cylinders can fail for a number of reasons, from wrong specifications to operator error. However, in this day and age with a number of engineering tools available to help reduce spec errors and strong expertise within the fluid power industry, one of the leading causes of cylinder failure is still seals. Whether the seals are sized wrong, incorrect material is spec'd, or just installed wrong, error in sealing can have a major effect on the entire cylinder operation. Cylinder operation is based on precise fluid pressure to both sides of the piston. If a seal breaks down and allows fluid to leak from one side of the piston to the other, or out of the cylinder all together, the pressures change, and your cylinder will no longer operate as intended. With over 100 years in the fluid power industry, Parker engineers have seen countless examples of how seal issues can escalate into much larger problems for a hydraulic system. Seal issues tend to fall into three main categories: hardening, bad installation, and erosion.
