How to fix a hydraulic cone crusher oil circuit blockage?

The hydraulic cone crusher's oil circuit features are primarily reflected in the design of its lubrication system. Its core function is to implement overload protection, discharge opening adjustment, and automatic cavity clearing through the hydraulic system, while also ensuring safe and intelligent operation of the equipment.
 

The hydraulic cone crusher's lubrication system utilizes a thin oil circulation system and primarily consists of an oil tank, oil pump, filter, pressure gauge, and safety valve. Lubricating oil circulates through two lines, lubricating key components such as the spherical bearings, main shaft bearings, and eccentric bearings, before ultimately returning to the oil tank. So, how to fix a hydraulic cone crusher's oil circuit blockage?

1. Check the oil circuit. First, turn off the power to the hydraulic cone crusher to ensure safety. Inspect the hydraulic system's oil circuit for blockage, including components such as the oil pipes, filters, and valves.

2. Clean the filter. If the oil pressure differential exceeds 0.04 MPa, the filter may be clogged and requires cleaning. Temporarily bypass the filter to confirm whether the filter is the cause of the blockage. Remove the filter, clean it, and reinstall it.

3. Check the oil line connections. Check that all oil line connections are tight and leak-proof.

4. Check the oil pump. If there is a problem with the oil pump, it may also cause oil line blockage. Check that the oil pump is working properly and replace it if necessary.

5. Change the oil. Sometimes poor oil quality can cause oil line blockage. Check that the oil meets specifications and consider replacing it with new hydraulic oil.
