Ever curious about how exactly the submersible water pump at industries, residents, or even the one you are using is working?
What are those components that drive such a great mechanism and work efficiently to meet your requirements.
In this post, we will take a look at a variety of products for submersible pumps, what their roles are, and how they work together.
Submersible water pump
A submersible pump drives the water out of the wells and towards the surface utilizing centrifugal drive. A hermetically fixed engine makes a difference in this activity. It remains associated with the body of the pump. A submersible pump capacities by changing over the revolving movement into motor energy. Kinetic energy is converted into pressure energy with the help of impeller blades. The main feature of this pump is to drive water out of different supplies while remaining submerged in the water or other liquids. This pump is similarly valuable in hot water-heavy oil applications. In this situation, a pressure-driven engine is used in wells rather than an electric engine. Pressure-driven engines are fuelled by pressurized fluid which is driven out by the submersible pumps. No priming is required for this device as it’s completely submersed into the water or other liquids. Less chance of cavitation builds up inside the pump which makes it an excellent choice for the buyers.
For industrial or drainage/sewage purposes single-stage submersible pumps are recommended whereas for municipal, commercial, industrial, or residential applications multi-stage submersible pumps are of greater choice.
The check-valve or non-return valve anticipates the backflow of liquid into the pump. The depth of submersible well-pump configuration is a deciding factor for the work site and the number of check-valves installed. One check-valve on the surface of the wellbore and another at the pump’s outlet section is required when the pump is situated at less than 200 feet depth. In any case, the number of check-valves increments indicates a pump is placed at a depth of 200 feet or more. The following factors are to be considered while or before installing check-valves.
- Friction loss of the piping.
- Pressure drops of the check-valve
- Weight of the submersible pump
- Velocity and volume of water
Easy Tie Adaptors
The easy-tie adapters are threaded into the discharge on the check-valve of the submersible pump and enter the poly riser pipe. At the well-head, it is possible to thread another adapter. After being threaded, an additional adapter is or can be connected to the ‘poly riser’. The protection of the submersible pump in the event of a pipe failure can be done with the support of the safety rope/cable.
The hose clamps seal the poly pipe to barbed insert fittings. This ensures watertight sealing and a secure connection that cannot be pulled off. Excellent corrosion resistance term stands for the clamps made of 300-series stainless steel. Simple maintenance is required for the proper operation of the stainless steel series. The strength of the alloy remains intact even at higher temperatures, which helps to improve the operation life of the working system.
The pump cables supply electrical power to the pump. A submersible pump is associated with a two-wire or three-wire pump.
- The two-wire pump- Starting capacitor is built into the submersible motor.
- The three-wire pumps- No capacitor is built into the submersible motor.
Operations of the submersible pumps are controlled by a pressure switch. The built-in membrane of the pressure switch is movable, it performs backward and forwards to exchange the pressure of the system.
Standard, medium, and heavy-duty are the different models of pressure switches available in the market. Different models of pressure switches are designed to control different levels of pressure and electrical ratings.
The pressure gauge is positioned in the accessory parts of the submersible pump. The functional status of a submersible pump can be checked and evaluated with the help of the pressure gauge.
Torque arrestors help to maintain the position of the submersible water pump, which is the center, and also prevent it from twisting inside the well-casing. They also play a crucial role in protecting the pump cable. They are installed on 1-inch and 1-1/4-inch riser pipes.
The impeller is a rotating component consisting of blades and its purpose is to accelerate fluid outward from the center of rotation, thus transferring energy. These rotating parts convert the kinetic energy of water into pressure energy and drive the water out of its original location. Noryl impellers and stainless steel impellers are widely used in the submersible water pump industry.
Diffusers are the casing to the impellers, role of the diffuser is to reduce the velocity of the water or liquid, give direction to the water or liquid and increase the pressure along the process. Noryl diffusers and stainless steel bowls are widely used in the submersible water pump industry.
Inlet and outlet Valves
- Inlet Valve- Draw the water into the pump.
- Outlet Valve- Release the water from the pump.
Sediments are the hurdles that reduce the efficiency and longevity of the water-treatment equipment. To handle this we need sediment filters, which help to prevent any sediment from getting into the water-treatment equipment.
The drain valves are also termed the boiler drain valves. They are used to collect water samples, collect water from systems and drain the tank.
If the pump components fail to operate it is important to stop the flow of water to the pump-house using ball valves. These valves are placed at the discharge side of the pressure tank.
