Some worm gearboxes on the market usually have temperature rise, vibration, and noise increase for a period of time. At the same time, the current continues to rise, and different fluctuations are generated. In severe cases, pumps can be found. The stroke becomes smaller.Over time, the abnormal wear of the worm gear box is very serious. So what is the reason for this?
After investigation, it was found that because the worm gear box regulating valve stem was relatively slender, straightness was difficult to maintain, and it was bolted to the socket, and it was difficult to maintain coaxiality after several disassembly and adjustments.Therefore, when the pump plunger stroke is adjusted, the original design of the fine-tuning process has changed. Adjustment lag and jamming often occur. Frequent axial displacement causes abnormal wear between the crankshaft and the inner hole of the worm gear sleeve, such as partial wear and jamming.As a result, the oil temperature rises, and the oxidation deterioration of the lubricating oil accelerates.The viscosity is reduced, and diffusion and adsorption occur between the friction surface molecules, which causes the structural changes of the surface materials, the metal softens, and the particles fall off into the oil.Friction surface will produce friction particle movement, local oil film is destroyed, causing abnormal blind damage.This forms a vicious circle, and the lubrication conditions continue to deteriorate, causing the worm gear box connecting rod bushing and the eccentric wheel, the crankshaft head and the socket to continue to wear, fall off, and the clearance exceeds the standard. The vibration and noise are significantly increased and larger, and the N-type crankshaft head The two connecting bolts bear a large moment, loose or fatigue fracture.The stroke of the pump plunger could not be adjusted, and the liquid level of the absorption tower was difficult to balance, and the pump was forced to be overhauled.
The above is the reason for the abnormal wear of the worm gear box. If there is a problem when using the worm gear box, please check and repair it in time to avoid this situation like the above.
