Submersible Pump
Submersible Pump: Workhorse in Action
An electrical submersible pump uses a tightly sealed motor. This means that the pump and the motor are encased in an airtight container. This is to prevent air and water from seeping into the motor.
This is very important because the whole device is submerged underwater, thus its moniker submersible pump. Any leak, however small, can short- circuit the device’s electrical components causing heavy damage to the pump and motor.
An air-tight seal protects the motor and prevents the formation of air bubbles. Bubbles in a liquid disturb the balance of pressure, thus when a bubble collapses or bursts it creates a shock wave causing pressure imbalance within the pump. This will then produce an irregularity that will damage the submersible pump.
Electrical submersible pumps produce an even and regular pumping function. It is therefore more balanced and stable. It is common knowledge that the absence of air bubbles protect and prolongs the life of the pump.
Force, Pressure and Power
The (hermetically) sealed motor is entirely submerged in water or liquid and is usually placed in the lowest level of a pond, pit or tank. Knowing the exact location is of very crucial since the electrical submersible pump can push water more effectively when it is placed in the lowest part of the liquid container.
Electrical submersible pumps perform more effectively at pushing water up to the surface as opposed to external pumps like jet pumps that forces water from the ground up.
The force exerted in pushing the liquid is lower than the force needed to hoist or pull the water to the surface. Thus electrical submersible pumps are designed to haul in the liquid with minimal opposing force that can damage the pump. This saves the user from the hassle of unnecessary maintenance cost and allows the pump to have a longer life span.
Aside from efficiency and dependability in performance, the electrical submersible pumps are made to be tough to withstand for long periods of use without part replacements and repairs.
Constant Pressure and Harsh Environment
The reason for making submersible pumps highly durable is because the pump is subjected to constant underwater use, making repairs and replacements difficult to do and labor intensive.
Manufacturing companies thus spend a lot of funding on design and research to guarantee the continued development at reinforcing and strengthening parts and their capacity.
In addition, the varying degrees of pressure and harsh environment to which submersible pumps are subjected to require such thorough research and study.
Aside from the stability of pressure, strength of parts, and
capacity of a submersible pump
, another reason why makers choose these types of pumps is because it is powered by electricity, which is in relatively constant supply.
