What to Do When Oil Temperature Rises Excessively in Hydraulic Cone Crushers

During operation, hydraulic cone crushers must prevent excessive oil temperature to avoid impacting production efficiency.

1. Effects of Excessive Oil Temperature:

Excessive oil temperature can cause numerous adverse effects on the hydraulic system, such as reduced viscosity, thinning and easier damage of the lubricating oil film, diminished lubrication performance, low volumetric efficiency of the crusher, accelerated mechanical wear, accelerated aging of the crusher's rubber seals, and consequent deterioration of sealing performance.

2. Solutions:

(1) Maintain normal oil levels in the tank to ensure sufficient oil for circulation and cooling within the system.

(2) Immediately relieve system pressure when actuators malfunction.

(3) Regularly clean cooling devices to maintain optimal performance.

(4) Select hydraulic oil viscosity based on ambient temperature: use high-viscosity oil in high temperatures and low-viscosity oil in low temperatures.

(5) During high ambient temperatures, avoid prolonged continuous operation of the crusher. Typically, when temperatures exceed 30°C, continuous operation should not exceed 4 hours.
