Screw pumps are important pieces of equipment for transferring fluids in industrial manufacturing, which has the features of easy mobility, small size, and other benefits that have made it popular. Nevertheless, the issue of increased noise during the screw pump's regular operation emerged out of nowhere. This could signal an equipment failure in addition to interfering with regular output. In order to assist you in quickly fix the issue, we will discuss the causes of the noise the screw pump is making in this post along with the corresponding ways of elimination.
I. Adjust operating parameters: Every screw pump specification has unique performance parameters that must be met. Noise issues may arise if the operating parameters—such as flow, pressure, etc.—exceed certain limits. Thus, one of the most efficient approaches to address the noise issue is to modify the operating settings to ensure that they fulfill the equipment's performance requirements.
II. Examine noise and vibration: Under normal circumstances, screw pumps run very smoothly and silently during operation. When a noise issue occurs, first check whether there is an unusual vibration present as well. Unusual vibrations can be caused by a variety of issues, such as damaged couplings, loose connection nuts, installation positions that are incorrect, and inadequate foundation connections. All that has to be done at this point is correct, tighten, or replace the matching damaged parts.
III. Check the internal wear and damage: Extended periods of operation can also cause wear and tear on components in screw pumps, which can lead to noise. This necessitates removing the machinery and examining the wear and tear of moving parts like gaskets and bearings. To get the equipment operating normally again, seriously damaged or deteriorating parts need to be replaced.
IV. Inspecting safety valves and filters: Clogged filters or unusual safety valve pressure settings are two more frequent sources of noise issues. To make sure the safety valve satisfies the equipment's operating requirements, it must have its pressure setting checked. Meanwhile, guarantee the fluids are transported smoothly, simultaneously check if the filter is clogged with foreign objects and clean or replace it as needed.
V. Add lubrication: Maintaining the progressive cavity pump's smooth operation requires proper lubrication. It's crucial to make sure that enough lubricant is provided, especially for new pumps or pumps that have been reactivated after an extended shutdown. To guarantee uniform lubrication dispersion, the unit should also be physically rotated a few times before commencing with tools.
By following the above methods, the issue of noisy screw pumps can be looked at and resolved one at a time. To guarantee operation safety, disconnect the power supply before beginning any maintenance or inspection. Most noise issues can be properly resolved to guarantee the screw pump operates steadily and efficiently with attentive inspection and maintenance.
