Mining Equipment Maintenance Tip: Sandvik Drill Rig Hydraulic System

Common Fault and Solution: Low Tramming Speed on Sandvik DL431 Drill

Issue: A Sandvik DL431 underground production drill rig experiences significantly reduced tramming speed, even when the engine is running at the correct RPM and the hydraulic oil is at the optimal temperature.

Root Cause Analysis: Low tramming speed is often related to a loss of pressure or flow in the tramming circuit. Potential culprits include worn-out hydraulic pumps or motors, a blocked filter element (e.g., 55043779), or, commonly, a failing relief valve or solenoid valve (e.g., 55194637) that is dumping pressure prematurely. A crucial inspection point is the pilot pressure line for blockages or leaks (possibly due to a deteriorated seal or O-ring, like 70011539 or 70012330).

Solution:

1. First, check the pressure setting of the main tramming relief valve.

2. Inspect and replace all hydraulic filter elements, ensuring the replacement filter is the correct specification.

3. Test the solenoid valves (55194637 or its coil 55044056) for proper switching.

4. If the problem persists, the hydraulic tramming pump may need to be serviced or replaced. Regular use of high-quality Sandvik Parts like seals (2835380, 55059887) and O-Rings (462527) during maintenance prevents such failures.

Understanding the Importance of a Washer

A Washer (Part Number 70801050) is a thin plate (typically disk-shaped) with a hole in the middle. Its primary function is to distribute the load of a threaded fastener, such as a bolt (e.g., C120004344, 15252438, 56205328) or screw (e.g., 2943590), which helps to prevent damage to the material being fastened. They also serve as a spacer, spring (wave washer), locking device (lock washer), and, in some applications, reduce vibration. The material and dimension of the Sandvik Washer (70801050) are crucial for the high-vibration environment of underground drilling equipment. Using a premium quality substitute like Hugeminer’s 70801050 ensures the fastener assemblies remain tight and reliable.
