Causes of Overheating Engine in Vertical Slurry Pumps

2026-04-15

To resolve the issue of engine overheating in vertical slurry pumps, it is first necessary to identify the root causes. Given the wide range of potential triggers, the most convenient troubleshooting method is elimination inspection.

First, check whether the water temperature gauge is malfunctioning. Replace it if it is inaccurate or defective.
Next, inspect for insufficient coolant in the water tank, and check for cracks or leaks in the inlet pipes and radiator. In addition to direct visual inspection, an air pressure test can be used to locate leak points.
Leaks on the radiator can be repaired by soldering; if a radiator tube is severely damaged, both ends can be clamped and sealed.
If minor leakage occurs during operation, it can be temporarily blocked with soap until maintenance is performed after shutdown.

When the engine of a vertical slurry pump overheats during operation, observe the fault symptoms carefully to identify and eliminate the cause. If the problem is not attributed to the above reasons, further inspect the engine body for cracks, check the condition of the water stop rings, and verify for leaks at the water pump drain hole. Finally, inspect the exhaust valve of the radiator cap; replace it if it is ineffective.
