Failure of a submersible motor is never convenient. At best, it is a nuisance. At worst, it can mean disaster. In this article, we will discuss some of the common reasons for the failure of a submersible motor, as well as solutions to this common problem. This article was originally published on Dec. 27, 2021 and has been updated for clarity. To help you decide if a submersible motor is right for your needs, we've broken it down into sections.

 

Submersible pumps are used in oil production and are available in different speds and depths. However, they tend to dry out when the fluid level drops below a certain minimum. A common cause of submersible motor failure is overheating, which damages the motor. A submersible pump is highly efficient and uses less energy to pump water than a conventional pump. It also saves energy because it is enclosed in oil.

 

Another disadvantage of submersible motors is that they are not cooled. The motor is completely enclosed and has no external shaft-mounted fan to dissipate heat. This means that the motor will not reach its efficiency peak if it isn't used for the right duty. This is why it's important to purchase a submersible motor with a heavy-duty cast iron frame. The frame of the motor should be large enough to move heat away from the motor.

 

Similarly, a submersible pump uses an electric motor. However, it also needs special overload protection. This will prevent the motor from stalling by cutting the power before the windings are damaged. This prevents any damage to the motor, which is important for its longevity. A submersible pump needs a mechanical seal to avoid fluid from flowing into the motor. If it fails, it might even fail. So, before purchasing a submersible pump, read on to learn about the important factors that determine the performance of your submersible pump.

 

A submersible motor is designed specifically for submersible applications. They are designed to be watertight and have a long life. Submersible motors must also be gas or air-operated, have a 15-minute duty cycle, and have appropriate hazardous environment certifications. They can also run safely in pump equipment. These benefits make submersible motors a popular choice for pumping equipment. If you're looking for a reliable and long-lasting submersible motor, make sure to contact an expert in the industry to help you choose the right one.

 

A submersible pump's casing may be made of different metals or polymers. The casing should be hermetically sealed to prevent liquid from leaking into the pump casing, causing a malfunction or even a short. Some pumps use double mechanical seals for tougher jobs. The cable used to power a submersible pump is typically about 50 feet, though it can be much longer in industrial settings. A float switch affixed to the casings may trigger the pump's activation.

 

Submersible pumps are ideal for applications such as seawater handling, sewage treatment plans, firefighting, and mine dewatering. If they are used in an electrically hazardous location, they must be rated for electrical hazards, such as those found in mines and oil fields. If they are used in an electrically-dangerous location, their design should also ensure that they do not spark when liquid is mixed with the water.

 

To power the submersible pump, you need an electric source that is of high voltage (between three and five kV). Previously, the electric cable had to be routed through jointed tubing, which was cumbersome to install. The new coiled tubing umbilicals allow the electric cable to be deployed with ease and sensor and control data to be transmitted. This means you can save time and money while installing your submersible pump.

 

A submersible motor has many advantages over its surface mounted counterpart. Its lower efficiency is offset by fewer mechanical and hydraulic losses and is often more durable. Additionally, submersible motors have a lower starting voltage, and a greater voltage range. Despite this, their general performance and protection are similar to that of standard squirrel cage motors. These factors can prevent unexpected failures and costly downtime. However, they do require a specialized knowledge of water pumps and their installations.

 

A submersible pump is an electric water pump with a submersible motor that is fully submerged in water. The motor is hermetically sealed and closely connected to the pump body. The fluid inside the submersible pump pushes water to the surface. The submersible pump works by converting rotary energy to kinetic energy. A submersible pump uses a diffuser to channel the water. The motor and the pump are submerged in water, making it suitable for use in a variety of situations.
