Preventive Maintenance for Submersible pumps

Preventive Maintenance for Submersible pump

This article will provide you with all the necessary information on how to make your submersible pump last longer with proper maintenance.

The process of keeping your Submersible pump in good working order is known as Submersible pump maintenance. 

It can be very helpful to have a complete checklist that the maintenance engineer follows while performing Submersible pump maintenance, as this will keep your Submersible pump operating properly and prevents them from breaking down. 

This entails routinely inspecting and maintaining your Submersible pump as well as replacing any worn-out parts.

Modern Submersible pumps are crucial pieces of machinery in the manufacturing and industrial sectors. These tools enable businesses to transport liquids and gases, which can be essential to operations.

Modern Submersible pumps are dependable and rarely need maintenance, although over time they do need some attention.

What are the different types of Submersible pump maintenance?

The process used to create the maintenance plan is the optimal way to categorize Submersible pump maintenance. Based on this, the four important categories of Submersible pump maintenance are as follows:

Remedial Maintenance

The most reactive kind of Submersible pump maintenance, known as corrective maintenance, entails replacing or repairing parts as necessary to keep a Submersible pump operating correctly.

Although this method may be required in some circumstances, it is frequently not the best choice because of its high cost and operational inconvenience.

Maintenance Upkeep

Another typical method of Submersible pump maintenance is preventive maintenance, which emphasizes proactive actions like routine inspections and adjustments.

This can assist prevent potential issues and keep the Submersible pump running as efficiently as possible.

Engineers perform a complete inspection and perform the necessary repair as and when required using a trustworthy checklist for Submersible pump maintenance. Several industries employ this strategy.

Prevention-Based Maintenance

Real-time monitoring of the condition of the Submersible pump and other components is accomplished by predictive maintenance using cutting-edge sensors and technology. 

This makes it possible for customers to identify potential flaws before they develop into major problems that call for pricey repairs or replacements. However, small-scale Submersible pump systems are not ideal for this form of maintenance because it is expensive.

Condition-Based Observation

This more recent method of Submersible pump maintenance evaluates the health of Submersible Submersible pump and other equipment using data gathered from sensors. 

A maintenance strategy that is specifically suited to the requirements of the equipment is then created using the information provided. 

This strategy may be less expensive and more efficient than conventional preventative maintenance plans for the Submersible pump in terms of downtime and expenses. A CBM system might, however, be expensive to set up.

Whether you employ one of these methods or a mixture of them, it is crucial to make sure that your Submersible pump maintenance program is properly created and carried out in order to maximize the functionality and durability of your Submersible pump

Plans for Submersible pump maintenance are also made depending on the systems they are intended to address, such as mechanical, electrical, and hydraulic systems. 

Parts that have worn out or malfunctioned as a result of regular wear and tear often need to be replaced during mechanical maintenance. 

When maintaining an electrical Submersible pump, it’s important to look for any signs of damage to the wiring and swap out any blown fuses. 

Depending on the amount of use, hydraulic Submersible pump maintenance may also require adjusting the fluid level or increasing the viscosity of the oil.

Basic Submersible pump Maintenance Checklist

The key to having a successful maintenance strategy is taking into account all the aforementioned elements and being able to work them into your Submersible pump checklist and timetable.

Daily Checklist for Maintenance

In your daily routine, you should preferably include the following items for your preventative maintenance Submersible pump checklist:

  • Examine the exterior for leaks.
  • Remove any clutter and listen for strange noises or excessive vibration.
  • Check for foaming or color changes in the oil.
  • Check the bearings’ temperature.
  • Check the gasket for any oil leaks
  • Check the self-flushing Submersible pump.
  • Verify heat tracing.
  • Examine water cooling and clean the bearing covers.
  • The primary goal of including a daily checklist in your calendar is to identify those annoying problems that, if ignored, could develop into flaws and costly fixes.

Checklist for Monthly Maintenance

The following items should be on your checklist when you plan your monthly maintenance appointments:

  • Top off the oil, if necessary.
  • Oil-bulb cleaning
  • Examine and replace the guards.
  • Clear the bearings of all dirt and debris.
  • The motor bearings with grease
  • Test the oil levels in the hydraulic governors.
  • Verify for leakage
  • Clear the Submersible pump of any exterior debris.
  • Setting up your monthly maintenance will be more involved than your daily Submersible pump maintenance and involve bigger, potentially time-consuming processes.

Checklist for Quarterly Maintenance

You must remember the following while planning your quarterly planned maintenance to maintain your centrifugal Submersible pump operating at its best:

  • Check for significant vibration damage in the Submersible pump and the motor.
  • Greasing bearings (this is usually done either every 2,000 hours or every three months, whichever comes first)
  • Replace the oil (this is usually done either every 2,000 hours or every three months, whichever comes first)
  • Verify the suction and discharge.
  • Verify the head pressure.
  • Check the tightness of the hold-down bolts.
  • Examine the shaft Submersible pump’s alignment.
  • Your quarterly maintenance is often completed with the change of the seasons and might involve a variety of tasks depending on environmental circumstances. The regularity and timetable of your Submersible pump maintenance program will also be impacted by how harsh your Submersible pump environment is.

Checklist for Annual Maintenance

You will typically go into further detail and assess the Submersible pump function in your annual preventive plan. You should keep track of your annual operations and benchmarking data each year, which could include:

  1. The flow rate of the Submersible pump
  2. Motor Amps
  3. Submersible pump vibration at suction pressure
  4. Submersible pump discharge pressure and head pressure

Your checklist for your annual maintenance should contain the following items:

Make sure your Submersible pump is unplugged from its power source before completing your annual checklist.

  • Verify the exterior for scale, debris, cracks, and rust.
  • clean chase threads
  • Examine the lubricating passageways for obstructions.
  • lubricated with grease
  • Changing out worn housings
  • Verify the stuffing box cover.
  • Analyze the use of energy
  • oil the motor’s bearings.
  • the level of the oil
  • verify flow rate
  • Look for rust in the casing and replace it if necessary.
  • Check the gasket for irregularities.
  • Replace the impeller if it has significant wear or bent vanes after checking it for erosion.
  • Check the shaft for corrosion and excessive wear.
  • Examine the shaft runout for wear.
  • Verify the mechanical seals.
  • Check for pitting in the seal chamber.
  • Inspect the chamber face for scoring.
