AI Technical Summary

Technical Problem

In traditional multi-cylinder hydraulic cone crushers, dust can easily enter the labyrinth seal during operation, leading to lubricating oil contamination and oil leakage. The existing positive pressure dustproof structure cannot effectively prevent dust from entering and the pressure is uneven, causing the lubricating oil to become dirty quickly and shortening the replacement cycle.

Method used

An air passage is set inside the main shaft, and two positive pressure dustproof fans are connected to the air passage and the air inlet respectively to form a complementary gas path, so as to balance the pressure inside and outside the labyrinth seal, prevent lubricating oil leakage and enhance the dustproof effect.

Benefits of technology

It effectively prevents dust and oil leakage from the lubricating oil, extends the lubricating oil replacement cycle, reduces equipment maintenance frequency, and lowers environmental pollution and economic costs.
